THE VICES OF SOCIAL MEDIA ON STUDENTS SUCCESS AT THE ADAMAWA STATE POLYTECHNI...ijcsit
Social media and social networking web sites have continued to gain supremacy in determining the
student’s success in education. It captures the attention of students and their tutors over the years. A social
media network is only an electronic links amongst its users which turned out to be a habit for students,
youngsters,
and even the grown person. The influence of social media on students is alarming and doing more harm
than good. The aim of the paper is to analyze the vices of social media on the academic success of students
of Adamawa State Polytechnic, Yola. The survey method of research was adopted to achieve the objectives
of the study. Some research questions were presented to the respondents where the results revealed that so
many (96 percent of them) usually spent much time on the social networking sites than to their academics.
As such, the academic success of the students suffers setbacks which lead to poor performance in the
student’s academics. It is therefore recommended that the networking sites should be built in such a way to
support student’s educational activities in a positive way, as this will help in attracting the students to ge
Impact of Social Media among Students’ Behaviors in Tertiary Institution of A...IJSRP Journal
The impact of social media among students behavior in tertiary institution has become worrisome. Social media is a means of connections among people in which they create, share, and exchange information and ideas in virtual communities and network. This craze for social media has led to a host of question regarding its impact among students behavior particularly in tertiary institution. This paper is set to study the impact of social media among students in tertiary institution in Adamawa State, Nigeria. A 5 likert scale questionnaire comprises of 19 questions was used as an instrument for data collection. 300 respondents sampled from 6 selected tertiary institutions in Adamawa State formed the population of the study. Descriptive statistics was used to analyze the data. The study revealed that social media has positive impact as well as negative impact on students behavior. The study further recommended that students need to be trained on better usage of social media so as to minimize its misused, School management should train and encourage students on how to use skype and other video conferencing tools to have discussion with lecturers and group members academically.

This study was carried out to ascertain the perception of students on the use of social media for
educational purposes. It was conducted in three tertiary institutions in Rivers State. The sample comprised 200
respondents randomly selected from three tertiary institutions in Rivers State. Five research objectives and four
null hypotheses were used for the study. Mean scores, ANOVA, multiple comparison test using schaffer model,
and Correlational Analysis were the statistical tools used in the study. The study found that social media is used
in the study. The study found that social is used for educational purposes in terms of communication, sharing
and exchanging ideas with improved engagement with technology. The study also revealed that social media is
frequently used for interactions with friends for classroom assignment, communication in and outside
classroom, promoting interactions during lectures, promoting informal learning, enhance course grades,
facilitating language exchange, video conferencing, creating room for educational and video sharing. In terms
of attitude of students, respondents generally have favourable attitude towards use of social media. The study
revealed significant differences exist in social media usage across the three universities involved in the study
and significant differences exist in usage of social media between male and female respondents; and in attitude
of students towards social media. Based on these findings, the study recommend that the use of social media
should be incorporated into the curriculum for enhanced universities education.

Usage of YouTube Content among Chennai Urban Women.pdfPugalendhiR
Abstract: The majority of YouTube users are college students, therefore it's critical to understand their usage patterns,
goals, and any potential psychological and behavioural effects. In order to determine the current trends in YouTube usage
among female undergraduate students in Chennai City, this study will examine the devices used, memberships subscribed
to, purposes used, and identity formation time spent networking, negative impacts experienced, and educational usage.
Data from a survey were analysed with SPSS-Statistic 19.0 software, and the findings were compared to the examined
literature. According to the survey, students' YouTube networking habits will eventually win out over parents' and
teachers' attitudes, and although while cell phones are currently prohibited in many college buildings, they will
undoubtedly be utilised in classrooms in the near future. The discoveries provide the current study in this area more depth.

How has social Media affected today’s Youth?
Social Media is a prominent part of today's life, especially among young people. Unfortunately, the users of social media do not stop to think about the effects it has on their lives. For instance, people are becoming anti-social while they are at the same time desperate to make more friends on Facebook or get more followers on Twitter. People need to know the impact of social media, both negative and positive, rather than just engage blindly. While there are many positive aspects of social media, the negative aspects are equally many. To help make the right choices, this paper will be an analysis of the effects of social media on youths, and how the negative effects can be handled.
This paper will help youths and parents understand the dangers of social media and know the boundaries they should use as they use it. Failure to do so will cause them to fall to varying traps and dangers that will have negative consequences. Social media is one sector of the internet that is greatly used by criminals. On this site, youths get exposed to cyberbullying, online predators and sexting. These dangers should be discussed to let people know their damaging effects and how they can be avoided. Other than the above-mentioned dangers of using social media, there are effects that are rarely discussed. For instance, teens are not aware of the dangers of exposing their address on public platforms. This paper will expose these dangers and many more as well as provide the most appropriate solutions.

Abstract
There are numerous ways, positive and negative, in which social media impact college students.
Understanding sheer volume of time and the type of activities for which college students use social
networking sites is crucial for higher education administrators. Researchers have begun to empiri-
cally examine impacts on students’ well-being and have found some preliminary results that call for
more research. They find that social media are not the problem—the problem is the specific use and
purpose of social media activities that make the difference.

Social Media networks have broad acceptance in current status. Almost everyone who has access with internet is linked with some kind of social communication using available social medias. Now social Medias are providing lots of utility to its users. This paper studies utility of its are useful for all learners . So the paper explain usefulness of any type of media in any field of education. Youth gain lot's of knowledge through technology in society .That why it is important for young learners Social media can be used effectively to build brand awareness, as well as by people to share brand positives and negatives. The point is that no matter how you slice it social media isnt a passing fad. It is becoming a standard communication platform that has dramatically changed the way that brands and consumers interact with one another. Mrs. Madhu | Miss. Shreya | Miss.

The design of Farm cart 0011 report 1 2020musadoto
This report describes the best designing of a 200cc FARM CART MACHINE which will be useful to the farm fields due to the fact that, the purchase, repair and maintenance are affordable to all level of income earners. Despite the cost effectiveness of the machine, the report also tries to justify that the machine can be used multipurposely as it serves the purposes of been used as farm transport, mowering machine, boom spraying and or mini planter with two rows. All these can be achieved as long as the implements are attached with respect to the power capacity of the farm cart.
The report tells only the design and testing of machine excluding its farm implements design. Some best reviews from other study projects done by other people in the world provided a good reference for designing and implementation of this project. The project is initially costly because it needs to develop a prototype and test the different first ideas.
The project report describes the important of choosing to use the designed farm cart machine compared to other farm machines at the market which are most efficiently to be used by farmers in their fields.
The challenges are inevitable in any project, here in designing of this 200cc farm machine, the major issue is the funding because the fund for this project is from the pocket which is always insufficient as it depends to the meals and accommodation money distribution sponsored from the HIGH EDUCATION STUDENTS LOAN BOARD (HESLB) thus it takes longer to accomplish the project by waiting another quarter of the semester to continue with the project which affects the other part of normal life(in terms of meals and accommodation).
The report recommends that, the department of engineering sciences and technology and Sokoine University of Agriculture as a whole should invest into this technology by utilizing fully the idea and funding the project for more better improvement so as to attain the desired standard that can with stand the different farm field factors. These when taken into consideration there is a possibility to achieve the industrialization policy in our country and thereafter it is a better approach to modern agriculture.

Hardeninig of steel (Jominy test)-CoET- udsmmusadoto
Controlling a material’s properties during processing is pivotal for any engineering field. A specific hardness for a metal is often a desirable characteristic for many applications, so controlling hardness is important during processing. To increase the hardness of steel, it is often quenched from a high temperature to form martensite, a hard yet brittle phase of iron. The extent of martensite formation, including hardness and depth of formation, is known as hardenability. This practical provides an experiment for measurement of hardenability in plain carbon steel and an alloyed steel according to, the Jominy End-Quench Test , (ASTM A255 – 10). The demonstration exercise involve quenching one end of a heated steel sample ,comparing and evaluating the hardness distribution using measurements obtained at different locations(distance interval) on the sample(specimens) surface.
1.1 The aim of the experiment
The aim of the experiment is to test the usefulness of the ultrasonic waves, by passing them through different
solids one can find out a lot of physical properties like young’s modulus , defects, Poisson ratio, Velocity of
sound in respective material this is due to the response of the received ultrasonic waves.
1.2 Theory of experiment
Ultrasonic testing (UT) is a family of non-destructive testing (NDT) techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion.
Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution. It is used in many industries including steel and aluminium construction, metallurgy, manufacturing, aerospace, automotive and other transportation sectors.

DIESEL ENGINE POWER REPORT -AE 215 -SOURCES OF FARM POWERmusadoto
The diesel engine (also known as a compression-ignition or CI engine), named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel which is injected into the combustion chamber is caused by the elevated temperature of the air in the cylinder due to mechanical compression (adiabatic compression). Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel that is injected into the combustion chamber ignites spontaneously. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to petrol), which use a spark plug to ignite an air-fuel mixture. In diesel engines, glow plugs (combustion chamber pre-warmers) may be used to aid starting in cold weather, or when the engine uses a lower compression-ratio, or both. The original diesel engine operates on the "constant pressure" cycle of gradual combustion and produces no audible knock.

The diesel engine has the highest thermal efficiency (engine efficiency) of any practical internal or external combustion engine due to its very high expansion ratio and inherent lean burn which enables heat dissipation by the excess air. A small efficiency loss is also avoided compared to two-stroke non-direct-injection gasoline engines since unburned fuel is not present at valve overlap and therefore no fuel goes directly from the intake/injection to the exhaust. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) can have a thermal efficiency that exceeds 50%.[1][2

ENGINE POWER PETROL REPORT-AE 215-SOURCES OF FARM POWERmusadoto
What is an Engine?
Before knowing about how the Petrol Engine works, let's first understand what an engine is. This is common for both petrol and diesel engines alike. An engine is a power generating machine which converts potential energy of the fuel into heat energy and then into motion. It produces power and also runs on its own power.
The engine generates its power by burning the fuel in a self-regulated and controlled „Combustion‟ process. The combustion process involves many sub-processes which burn the fuel efficiently and results in the smooth running of the engine.
These processes include:
The suction of air (also known as breathing or aspiration).
Mixing of the fuel with air after breaking the liquid fuel into highly atomized / mist form.
Igniting the air-fuel mixture with a spark (petrol engine).
Burning of highly atomized fuel particles which results in releasing / ejection of heat energy.
How does an Engine work?
The engine converts Heat Energy into Kinetic Energy in the form of „Reciprocating Motion‟. The expansion of heated gases and their forces act on the engine pistons. The gases push the pistons downwards which results in reciprocating motion of pistons.
This motion of the piston enables the crank-shaft to rotate. Thus, it finally converts the reciprocating motion into the 'Rotary motion' and passes on to wheels.
A petrol engine (known as a gasoline engine in American English) is an internal combustion engine with spark-ignition, designed to run on petrol (gasoline) and similar volatile fuels.
In most petrol engines, the fuel and air are usually mixed after compression (although some modern petrol engines now use cylinder-direct petrol injection). The pre-mixing was formerly done in a carburetor, but now it is done by electronically controlled fuel injection, except in small engines where the cost/complication of electronics does not justify the added engine efficiency. The process differs from a diesel engine in the method of mixing the fuel and air, and in using spark plugs to initiate the combustion process. In a diesel engine, only air is compressed
TRACTOR POWER REPORT -AE 215 SOURCES OF FARM POWER 2018musadoto
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery used in agriculture or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage, but nowadays a great variety of tasks. Agricultural implements 0may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised.
The word Tractor is derived prior to 1900, the Machine were known as traction motor (pulling-machine).After the year 1900 both the words are joined by taking ‘Tract’ from Traction and ‘Tor” from motor calling it a Tractor.
In our Country tractors were started manufacturing in real sense after independence and at present we are self-sufficient in meeting demand of country’s requirement for tractors. Our country is basically an agricultural country where 75% of our population is directly or indirectly connected with agriculture. This cannot be produced with our conventional bullock pulled agricultural implements. Tractor is one of the basic agricultural machines
used for speeding up agriculture production.
WIND ENERGY REPORT AE 215- 2018 SOURCES OF FARM POWERmusadoto
Wind is the flow of gases on large scale. On the surface of the earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases and charged particles from the sun though space, while planetary wind is the outgassing of light chemical from a planet’s atmosphere into space. Wind by their spatial scale, their speed, the type of force that cause them, the region in which they occur and their effect. The strongest observed winds on planet in solar system occur on Neptune and Saturn. Winds have various aspects, an important one being its velocity, density of the gas involved and energy content of the wind.
Wind is almost entirely caused by the effects of the sun which, each hour, delivers 175 million watts of energy to the earth. This energy heats the planet’s surface, most intensively at the equator, which causes air to rise. This rising air creates an area of low pressure at the surface into which cooler air is sucked, and it is this flow of air that we know as “wind”. In reality atmospheric circulation is much more complicated and, after rising at the equator air travels pole wards. As it travels the air cools and eventually descends to the earth’s surface at about 30° latitude (north and south), from where it returns once again to the equator (a closed loop known as a Hadley Cell). Similar cells exist between 30° and 60° latitude (the Ferrell Cells) and between 60° latitude and each of the poles (the Polar Cells). Within these cells, the flow of air is further impacted by the rotation of the earth or the "Coriolis Effect". This effect creates a sideways force which causes air to circulate anticlockwise around areas of low pressure in the northern hemisphere and clockwise in the southern hemisphere
In summary, the origin of winds may be traced basically to uneven heating of the earth’s surface due to sun. This may lead to circulation of widespread winds on a global basis, producing planetary winds or may have a limited influence in a smaller area to cause local winds.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. Abstract
This study was carried out to investigate the use of social media among the
undergraduate students of Sokoine University of Agriculture(SUA).In the context of
today’s electronic media,socialmedia have come to mean individuals, using the internet
and web application to communicate in previously impossible ways.This is largely the
result of a culture wide paradigm shift in the uses and possibilities of the internet.the
objectives of study are to examine various categories of social media used by
undergraduates, also the benefits and dangers of using social media .Data were collected
via questionnaire and observation from the sample of 100 undergraduates.
3. 1. INTRODUCTION
1.1 Background of the study
Social networking sites are fast becoming very popular means of both interpersonal and public
communication in Tanzania. Social networking sites are modern interactive communication
channels through which people connect to one another, share ideas, experiences, pictures,
messages and information of interest. Boyd and Ellison (2007) define social networking sites as:
‘‘Web based services that allow individuals to construct a Public or semi- public profile within a
bounded system (2) articulate a list of other users with whom they share a connection and
(3)view and traverse their list of connections and those made by others within the system.(pp.78-
100.) They are interactive networks which information and communication technology (ICTs)
bequeath to the modern society through the instrumentality of the Internet and the
telecommunication gadgets. The Internet makes it possible to expand the networks and to
increase the possibilities for communicating with wider audiences on the globe. The interactive
aura of the new media confers an unprecedented popularity on them. Also the ubiquity of the
social networking sites within their short period of arrival is unparalleled in the annals of media
industry.
The Social networking sites at the Sokoine University of Agriculture started to be widely used
around 2011 when there was wide spread of smartphones, free wireless networks like TWIGA,
TSUNAMI,BIOPROCESS,DASP,SNAILand cheap internet bundles like University offer
bundles. Thus since inception the social networking sites which are widely used at SUA among
undergraduates are like Facebook,Whatsapp,Instagram,Yahoo,Google+,Jamiiforums and Gmail
also there is SUA Student Information System(SUASIS) which was created in 29 August 2013.
Thus since inception social networking sites like Facebook, WhatsApp etc are widely used for
Communication purposes and sharing various information while others like Google, Email sites
like Yahoo, Gmail, Hotmail, Rocket mail are widely used for study purposes like Searching for
learning materials and submitting class assignments.
1.2 Statement of the problem
Over the years, social networking sites have metamorphosed from few-user-based sites into
phenomena that have become niches for billions of users. The growth and popularity of social
networking sites have generated concerns among school authorities, communication experts and
socio-psychological researchers about the benefit and potential risks facing undergraduates, as
they engage in online social networking to cater for their social and information needs rather
than oral or face-to-face communication. Throwing further light on the risk of social networking
sites on oral communication among their users, Sherry Turkle (2012), the founder and director
of the MIT initiative on technology and self, asserted that the convenience the social networking
sites give users to communicate with one another can damage their interpersonal communication.
4. Also, social networking sites make the users see one another as “objects” to be accessed and only
for the parts that the users find useful, comforting amusing. What is more, addiction to social
networking sites can establish feelings of loneliness and increase feelings of insensitivity to
disconnection, according to John J. Cacioppo, a neuroscientist at the University of Chicago
(Cacioppo, 2009). Hence, there is the need to fashion out some means of selecting and using the
right social networking site responsibly. This study is concerned with the trend of use of the sites,
what benefits students derive from using the sites, the dangers associated with them and ways to
avert such dangers.
1.2.1 Objectives of the study
The general purpose of the study is to find out the place of the use of social network sites by
undergraduate students of the Sokoine University of Agriculture. The specific purposes of the
study are as follow:
1. To examine the various categories of social networking sites.
2. To examine the extent of usage of social networking sites by the undergraduate students
of the SUA.
1.2.2 Research Questions
1. What are the various categories of social networking sites?
2. To what extent do the undergraduate students of the Sokoine University of Agriculture use
the social networking sites?
5. 2. LITERATURE REVIEW
Social networks are online services, platforms or sites that focus building and reflecting social
relations among people, who, for example, share interests and or activities. Social networking
sites are websites that allow those who have account with them to communicate with a selected
group of friends (Awake,2011). Social networks comprise a representation of each user (often a
profile), his or her social links, and a variety of additional services (wikipedia, 2011). Most of the
social networks are web-based and provide mean for their users to interact via the Internet, such
as e-mail and instant messaging; social networks allow activities, events and interact within their
individual networks.
The inception of social networking sites, to facilitate new forms of computer-mediated social
interaction, evolved from early suggestions. Measure and efforts to support social networks via
computer-mediated communication (CMC) were made in many early online services; include
unset, bulletin board service like America online, prodigy, and CompuServe. Early social
networking on the World Wide Web began in the form of generalized online communities such as
the glob.com (1995), Geocities (1994) and Tripod.com (1995) (wikipedia, 2011).
Characteristically, many of these early communities focused on bringing people together to
interact with one another through chat rooms and encouraged users to share personal information
and ideas via personal web pages by providing easy-to-use publishing tools and free or
inexpensive web space. Some network such as classmates.com, Facebook, Twitter etc. took a
different approach by simply having people link to each other through e-mail addresses. New
social networking methods were developed at the end of the 1990’s and many sites began to
design more advanced features for users to find and manage friends. This newer generation of
social networks began to blossom with the emergence of six degrees.com in 1997, followed by
make out club in 2000, freinster in 2002 and myspace in 2003. Social networking sites have
become a new means through which individuals can interact and communicate with friends in
distance places. As at September, 2011, facebook had a total number of 800 million active users
(wikipedia, 2011). Today, it is estimated that there are now over 200 active social networks using
a wide variety of social networking models. In Tanzania, the number of social network users is
on the high side. According to social bakers, a facebook statistics site, according to the site,
facebook has an estimate of over 4 million Tanzania users, with the males dominating 65% while
the females have a 33% domination.
6. 3. METHODOLOGY
This is the systematic, theoretical analysis of the methods applied to field of study. The
methodology is going to present the area of study ,sample used as well as data collection tools.
3.1 Area of study
The area of study is Sokoineuniversity of agriculture (SUA) which is located in Morogoro
region. The choice of the area was for proximity and to ensure effective distribution and
collection of data through the use of observation and interview. The population of the study
comprises the entire undergraduate students of Sokoine University of agriculture. The population
figure of students at Sokoine university of agriculture is eight thousand eight hundred and thirty
seven (8837) (suanet, March 2017). Simple random sampling was used as the method of drawing
a sample of 100 students from the population so that each member of the population is given an
equal and independent chance of being selected.
3:2 Data collection methods/ tools
3:2:1 Questionnaire
The instrument for data collection was a self constructed questionnaire .It was titled the use
of social networking sites among undergraduates students of Sokoine University of
agriculture.The questionnaire consist of two parts, part A and B. Part A is on the background and
characteristics of the respondents while part B was divided into six clusters. Cluster 1 contain
various networking sites used by the respondent with sixteen items while cluster 2 deals with the
extents of used of social networking sites by the respondents with sixteen items. Cluster 3 is all
about the level of agreement as to the purpose of using social networking sites with eleven items
while cluster 4 is on level of agreement as to benefits of social networking sites with seven items.
Cluster 5 is danger encountered in using social networking sites with nine items while cluster 6 is
on strategies for ameliorating the dangers of social networking with six items. The questionnaire
was homogeneously keyed in a 4-poing scale and the subjects were guided to respond to each
items thus: SA-strongly agree; A- agree; SD-stronglydisagree;D-disagree. VGE-very great
extent; GE-great extent; LE-little extent; NA-not at all.
One hundred copies of questionnaire were distributed to the respondent (undergraduate students
of SUA) and were collected.
3:2:2 Observations
The method was constructed to observe various categories of social networking sites used by
SUA undergraduates, the extent of using social networking sites and the purpose of using social
networking sites. Also to determine benefits of using social networking sites and to identify the
dangers associated with social networking sites

In this Chapter, the research findings were discussed in line with the research questions and
literature review. Various categories of social networking sites used by undergraduate students of
Sokoine University Of Agriculture .The percentage representing the rate of agreement in the
questionnaire reveal that the Categories of social networking site used by undergraduate student
of Sokoine University of Agriculture include Facebook, Whatsapp, Googl+, YouTube, Yahoo,
Skype, Blackbery messenger, Blog.
The respondents responded positively on purpose of using social networking sites. The findings
of this study show that Sokoine University of Agriculture undergraduate students use social
networking sites for different purposes and the sites often favour them. The investigation
revealed that Sokoine University of Agriculture undergraduate students use the social networking
sites to communicate with friends, watching movies, for discussing national issues like politics,
economy and religious matter and for academic purposes.
Conclusion
The results obtained from this study have shown that a reasonable number of Sokoine
University of Agriculture Undergraduate students use the social networking sites. Therefore, the
popularity of the social networking usage by undergraduate students of university of Sokoine
University of Agriculture and the benefits it has on the student –users have been confirmed from
the findings of this study. There are also various purposes for which the students use the social
networking sites to achieve and that have been investigated.
Finally, from the results. Technology is a double-edged sword can be used in ways beneficial
and otherwise, its power for bad and good resides in the user it is instructive to note that the
relevant government authorities and other sponsors of the students, have to take good measures
to ensure that they(student) are made to be aware of how and why they use the social networking
sites.
Recommendations
Based on the findings drawn from this study the following are recommendations to the university
authorities and the students at Sokoine University of Agriculture.
Recommendation to University Authorities
1. Regulation of the use of GSM Phones during lectures: Hence the students access the various
social networking sites through their mobile phones, it is advisable that Sokoine university of
9. Agriculture governing councils and the University senate has to enact laws, making students’ use
of phones during lectures an offence which shall attract drastic punitive measures for the culprits.
2. Tertiary institutions should organize a seminar to enlighten students on the not too-good
aspects of using social networking sites as media of interaction. This can be done by exposing
students to the importance of face to face communication in the creation of real communication
or message sharing. Seminars would be helpful here.
3. Motivation to bravura and scrupulous users of the social Networking sites: One of the most
Popular social networking sites, facebook(which is one of the most successful business
enterprise in the world) was said to be developed by Boyd and Ellison(2007).He founded
facebook by hacking Harvard’s database containing identification images of students. From
this Sokoine University of agriculture students have to be motivated that any of the students who
invents a useful device through the usage of the social Networking sites will be rewarded by the
university.
4. Provision of laws on the content of social media: There has to be laws guiding the
students’ use of the social networking sites and what they disseminate through the media.
