In the past, Since learning of basic knowledge was very important. The behaviourist approach was generally use as traditional instruction. In this instructional approach, knowledge is merely abstracted and the “learning” and “teaching” process is viewed as individual process, and “learning” is conceived as the accumulation of stimulus-response association. Drill and practice play an important role in this process. Also, the assessment practice is mainly based on testing, basic knowledge. Because, the proof of learning
generally is seen as changing the behaviors and increasing the right answer in test,

The essence of this research was to investigate the influence of self-esteem on students’ academic success in Calabar metropolis of Cross River State of Nigeria. Two hypotheses were raised to guide the study. Literature review was carried out accordingly based on the variables of the study. The random sampling technique was adopted which sampled three hundred and forty-five (345) students who were drawn from fifteen secondary schools which represented all the public secondary schools in the area of study. The Self-Esteem and Academic success questionnaire (SEASO) and Achievement Test in mathematics and English Language (ATMEL) were used to collect data. The independent t-test analysis was used to test the hypotheses of the study. The findings showed that there is a significant difference in the academic success of students with positive self-esteem than those with negative self-esteem. This implies that self-esteem significantly influences students’ academic success. Based on findings of the study, it was recommended that students should boost their self-esteem as it is an important factor that strengthens the prediction of academic success in Mathematics and English Language. There should be school counseling intervention in improving self-esteem among students. Students should be trained on how to improve greatly in their self-esteem and academic efficacy.

Analysis of Students’ Error in Learning of Mole Concept among Selected Senior...iosrjce
The purpose of the study was to determine the students’ error in learning mole concept A total of 120
Senior Secondary 2 chemistry students randomly selected from two private schools in Zaria with a mean age of
17 constituted the sample size for the study. The Chemistry achievement tests (CAT) and Mole concept
diagnostic test (MDT) were used as the instruments for the study . Diagnostic interview and semi-structured
questionnaire were also used to identify at which level students’ errors occur in solving problems and the
perception of students towards mole concept was that success can be achieved in problem solving with a good
grasp of the subject and an above average mathematical ability. The type of error analyzed were based on the
modified Newman Error Hierarchy Model that includes reading type error, comprehension, transformation,
process skill, and encoding error. Data was analyzed using mean, percentage, frequency, Duncan’s (MultipleRange)
and Wilcoxon test at P< 0.05. The study found out among others that the error most students make
involving transformation and process skill in solving problems in mole concept was significant (P<0.05) .There
was no error found in reading. The number of students who made encoding error and carelessness was small.
The students’ error in solving problems in mole concept was due to their weaknesses in stoichiometry and basic
arithmetical operations. The need for an appropriate and friendly pedagogical approach in the learning of mole
concept was proposed and recommendations were made based on findings
READING COMPREHENSION AND PROBLEM SOLVING SKILLS OF GRADE SEVENSTUDENTS: A MI...AJHSSR Journal
ABSTRACT: The purpose of this study was to determine the relationship between the extent of students‟
reading comprehension and problem solving skills and identify teaching strategies that would address the
problem in teaching problem solving in Mathematics. The research utilized mixed explanatory design. The
subject consists of 189 grade 7 students who were part of the general section enrolled at Davao City National
High School. Purposive sampling was used in identifying the respondents taking the reading comprehension test
and problem solving test while random sampling was used in identifying participants for the key informant
interview. The result of the study revealed that students reading comprehension and problem solving skills were
at developing level. Moreover, reading comprehension skill was a predictor of problem solving skill. This
means that students‟ problem solving skill is dependent on their reading skills. Results also showed from the
conducted focus group discussion that students gave importance to vocabulary and main idea in learning
problem solving. Furthermore, using differentiated instruction was the identified best teaching strategy to
understand problem solving.
This study aims to investigate whether student anxiety about the subject of mathematics has any effect on the achievement of middle-school students in Amman, Jordan. It also aims to investigate whether student gender plays a role. The study sample consists of 180 seventh grade students enrolled in Amman public schools during the 2018/2019 academic year. These are distributed into three levels of anxiety as displayed by the students: low, middle, and high. Then, math anxiety measurements are collected, the validity and reliability for which are verified. The results reveal that there are statistically-significant differences in achievement between the middle level of math anxiety and the two other extremes. It is found that middle anxiety level have a positive effect on achievement, whereas for low and high math anxiety levels, no differences in achievement are perceived. In addition, no statistically significant differences (α≤0.01) were found between males and females with regards to math anxiety; and there is no interaction between the level of math anxiety and gender in achievement.

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.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

CHAPTER I
INTRODUCTION
Background of the Study
Quantitative Literacy, as defined by the Mathematical Association
of America (MAA), is the ability to apply the minimum computational
competency or fluency to solve problems in the real world
(http://www.maa.org/college-algebra). It is implicit that when a person
is quantitatively literate, he is able to use his mathematical skills in
dealing with situations in his life, whether it is in the complex line of
business, economics, and politics or in the simple context of time
reading, scheduling, and many others. Indeed, Mathematics is
necessary.
One mathematics subject that is necessary to person’s life is
College Algebra. Packer (2004) explains that College Algebra is the
introductory mathematics subject to any university or community
college. He added that College Algebra is the starting course for students
to be trained logically as they would deal with algebraic expressions,
axioms of equations, functions and the like. Furher, Leeyn (2009)
exemplifies that College Algebra is a critical element to 21st century jobs
and citizenship. Gateschools staff (2013) also asserts that it is the
gatekeeper subject. It is so because it is used by professionals ranging
from electricians to architects to computer scientists. Robert Moses
8. 2
(2009), founder of the Algebra Project, says that learning College Algebra
is no less than a civil right. As such, College Algebra is really very
important.
However, no matter how important College Algebra is, it is still
considered by most students as a non-helpful subject. According to a
paper presented in the Mathematics Association of America (MAA)
conference in the year 2009 which revealed that College Algebra is the
last mathematics course many students take. A majority entered the
classroom having already decided that it would be their final
mathematics course. Data, contained in the same conference report,
indicated that only one in ten College Algebra students go on to take
other higher math subjects. Many would skip College Algebra if they did
not have to pass it to get the degree they need to enter their chosen
career field. In addition, enrollment in this subject tends to fall
dramatically when colleges make quantitative reasoning or intermediate
algebra the requirement. It was also reported that, a few years after
finishing the course, the students cannot recall anything they learned.
All of these pinpoint to the fact that college algebra seemed hard for most
students (http://www.maa.org/college-algebra). As a result, readiness,
evident in their performances, declines. According to the New York
Times, in the last fall of 2013, results from national math exams stirred
9. 3
up a tempest in a standardized test. It turned out that math scores
declined more quickly. It was also mentioned that math scores haven’t
improved since 2007 (http://www.nytimes.com/). In addition, Shepherd
(2005) revealed that most students do not excel in their Algebra course.
Most of them cannot perform indicated operations, especially when
fronted with word problems. Students find it hard to solve problems in
Algebra. Some just do not answer at all. These situations reflect poor
understanding of and performance in the course (The Journal of
Language, Technology & Entrepreneurship in Africa, Vol. 2, No.1,
2010).Moreover, Kuiyuan (2009) also mentioned that in University of
Florida, the student’s success rate in College Algebra is more than the
desired level. Kuiyan (2009) stressed that with this trend in dismal
performance, the readiness of students in such subject is very low.
In the Philippines, College Algebra is a pre-requisite subject in all
course curricula. CHED Memorandum Order 59 series of 1996 mandates
the inclusion of College Algebra as a basic subject in all courses. The
country is not exempted from the predicaments on College Algebra
performance. A recent study of on the readiness graduating high school
students of Marian Schools in College Algebra revealed that their
readiness is only at the moderate level. This means that the students did
10. 4
not yet fully attain the desired competence to be able to hurdle the
demands of College Algebra.
In the provincial scene, the recent study of Ragma (2014) revealed
that the students have only poor performance in College Algebra. In
Saint Louis College, the study of Oredina (2009) revealed that the
students had only moderate performances. Additionally, the mathematics
instructors, the researchers of the study, observed that most students
enrolled in College Algebra are not yet ready for the subject. This is
shown in their quizzes, exams and grades. In fact, in a class of 50, more
than 40% have failing grades in their prelim grades. The state of dismal
performances in this subject point out to the fact that the students are
not ready to take up College Algebra.
The foregoing situations encouraged the math instructors to
embark on assessing the level of readiness of SLC students in College
Algebra for school year 2013-2014 as basis for formulating learning
activity sheets.
Theoretical Framework
E. Thorndike (1978) proposed the law of readiness. The readiness
theory states that a learner’s satisfaction is determined by the extent of
11. 5
his preparatory set. It implies the need of acquisition of necessary pre-
requisite skills so that learners will be ready to tackle the succeeding
lessons and at the same time, they can anchor the new lessons to the
previous ones. This theory serves as the main foundation of the proposed
study since it looked into the level of readiness of students in College
Algebra.
Central to the theory of readiness are the concepts where the
theory is founded. According to the theory, there are several factors
affecting readiness. These include maturation, experience, relevance of
materials and methods of instruction, emotional attitude and personal
adjustment. In addition, the same theory proposes several strategies in
building readiness skills. These strategies include the analysis of skills
using diagnosis or pre-assessment and the design of an instructional
intervention programmed to match the individual’s level of readiness.
This central concept of the readiness theory provided the justification of
formulating a College Algebra readiness test as a form of diagnostic
assessment among students.
Moreover, Jeane Piaget (1964), a Swiss psychologist and biologist
formulated one of the most widely used theories of cognitive
development. Piaget’s theory stresses that the potentials of formal
operational thought develop during the middle school years. These
12. 6
potentials can be actualized by ages 14, 15, or 16 years. Apparently,
learning mathematics involves formal operational thought. The research
of Piaget shows that individuals are formal operational thinkers by ages
15 or 16, the usual ages of college freshmen in the Philippines. In this
connection, this study utilizes this Piaget’s theory to investigate whether
a group of college freshmen performs at the expected level of formal
thought, in other words, if they are ready to take up collegiate courses in
Mathematics.
The law of readiness and its central concept laid the concepts in
structuring the research. The cognitive development theory, on the other
hand, gave additional foundations in formulating the learning activity
sheets.
The learning activity sheets are worksheets that contain the topic,
its objectives, activities with the teacher and activities for group and
independent learning.
Conceptual Framework
Teaching and learning mathematics becomes more meaningful and
directed when the teachers know the level of the learners’ preparation
and when the learners are ready to grasp concepts presented in the
teaching-learning process. In this manner, the teachers know where to
13. 7
start, how to start and what concepts need to be more emphasized;
students, on the other hand, know when to study more and where to
focus on.
As part and parcel of improving performance, instructional
materials such as worktext, activity books and activity sheets are
inevitable. The learning activity sheets are instructional support
materials that provide supplements to classroom instruction and give
opportunities for students to study on their own and deal with some
more additional exercises. These materials provide avenue for the
students to enhance more their competencies required in each topic by
providing relevant activities pertinent to the full understanding of the
topic. Students can even have advanced studies and make study work
using the learning activity sheets.
It is in this light that this study is formulated and thought of. The
research paradigm in figure 1 highlights the relationship of the indicated
variables. The input incorporates the profile of the respondents along
sex, high school graduated from and the mathematics high school final
grade. It also includes the level of readiness of the students along
elementary topics, special products, factoring, rational expressions,
linear equations, systems of linear eqautions and radicals and
exponents.
14. 8
The process includes the interpretation and analysis of the profile,
the level of readiness of the students, the strengths and weaknesses
based on the level of readiness, the correlation between the profile
variables and the level of readiness, and the difference among the level of
readiness among the three colleges: ASTE-IT-CRIM, CCSA, CEA.
The output, therefore, are validated learning activity sheets in
College Agebra.

along the specified topics in College Algebra. This is categorized into:
highly ready, ready, slightly ready and not ready.
Strengths. An area under readiness level is considered strength
when it has a decriptive equivalent of highly ready and above.
Validated Learning Activity Sheets. This is the output of the
study. It consists of the rationale, the learning objectives and the varied
activities that address the needs of the students based on the identified
level of readiness.
Weaknesses. An area under readiness level is considered a
weakness when it has a decriptive equivalent of ready and below.

CHAPTER II
METHOD AND PROCEDURES
This chapter presents the research design, the sources of data,
data analysis and ethical considerations.
Research Design
The descriptive method of investigation was used in the study.
Calmorin (2005) describes descriptive design as a method that involves
the collection of data to test hypothesis or to answer questions regarding
the present status of a certain study. This design is apt for the study
since the study is aimed at describing the level of readiness of students
in College Algebra.
Further, since the comparisons on the level of readiness among the
three departments and the relationship of profile and the level of
readiness were established, the descriptive-comparative and the
descriptive-correlational methods were employed, respectively.
Sources of Data
Locale and Population of the Study
22. 16
The total population of 1,349 students enrolled in College Algebra
for the first semester, school year 2013-2014 was surveyed. Since the
population reached 500, random sampling was conducted. The sample
population of the study was computed using the Slovin’s Formula. The
formula is: n =
where:
n = the sample population
N = the population
1 = constant
e = level of significance @ 0.05
Thus, the sample population is 309 students distributed according
to the three departments: 72 for CASTE-IT-CRIM, 155 for CCSA and 82
for CEA.
Table 1 shows the distribution of the number of specified
respondents.

CCSA 675 155

Instrumentation
Documentary analysis was used to get the needed data for profile,
specifically for gender, high school Math IV final grade and type of
high school graduated from.
To gather the data pertinent to the level of readiness, a researcher-
made test was made. The researcher-made test is 50-point item test
covering all the topics in College Algebra. (Please see appended table of
specifications)
The readiness test was administered by all the Mathematics
instructors during the 2nd week of June in their respective classes. A
one-hour period was allotted to each student. The instructors
guaranteed that calculators were not utilized in taking the readiness
test.
Data Analysis
24. 18
The data which were gathered, collated and tabulated were
subjected for analysis and interpretation using the appropriate statistical
tools. The raw data were tallied and presented in tables for easier
understanding.
For problem 1, frequency counts and rates were used to determine
the status of the profile of the respondents along gender, high school
Math IV final grade and the type of high school graduated from. The
rates were obtained by using the formula below:
R = n x 100
N
where: R - rate
n - number of frequencies gathered in each item
N - the total number of cases
100 – constant
For problem 2, mean and rates were utilized to determine the level
of readiness in College Algebra. The formula for mean is as follows
(Ybanez, 2002):
M = ∑x
N
Where: M – mean
x – sum of all the score of the students
25. 19
N – number of students
For problem 3, the Pearson-r moment of correlation was used to
determine the significance of relationship between profile and the level of
readiness in College Algebra. The formula according to Ybanez (2002) is:
where: X – observed data for the independent variable
Y – observed data for the dependent variable
N – size of sample
r – degree of relationship between X and Y
The computed correlation coefficients were subjected to
significance; thus the formula used
(http://faculty.vassar.edu/lowry/ch4apx.html) was:
where: r – computed correlation coefficient
n-2 – degree of freedom
t – degree of significance for r
For problem 4, t-test independent (t-test between means), taken
two at a time was used to determine the difference in the perceptions of
26. 20
the respondents. The formula for t-test for means
(http://en.wikipedia.org/wiki/Student%27s_t-test) is:
where:
= estimator of the common standard deviation of the two
samples
n = number of participants, 1 = group one, 2 = group two.
n – 1 = number of degrees of freedom for either group
n1 + n2 – 2 = the total number of degrees of freedom, which is used
in significance testing.
t = degree of difference
For problem 5, the major strengths and weaknesses were deduced
based on the findings, particularly on the level of readiness in College
Algebra through statistical ranking. An area was considered strength
when it received a descriptive rating of highly ready; otherwise, the area
was considered a weakness.
27. 21
The MS Excel Data Analysis Tool was employed in treating the
data.
Data Categorization
For the profile of the students along high school grade in Math IV,
the scale system was used:
Grade range Descriptive Equivalent
92.6-97.00 Outstanding Performance
88.2-91.59 Very Satisfactory Performance
83.8-88.19 Satisfactory Performance
79.4-83.79 Fair Performance
75-79.39 Poor Performance
For the level of readiness in each topic in College Algebra, the Scale
System was utilized.
Elementary Topics/ Factoring
Score Range Level of Readiness/ DER
7.20-9.00 very highly ready
5.40-7.19 highly ready
3.60-5.39 fairly ready
1.8-3.59 slightly ready

5.60-7.00 very highly ready
4.20-5.59 highly ready
2.80-4.19 fairly ready
1.40-2.79 slightly ready
0.00-1.39 not ready
Rational Expressions/ Linear Equations in One Variable
Score Range Level of Readiness/ DER
6.40-8.00 very highly ready
4.80-6.39 highly ready
3.20-4.79 fairly ready
1.60-3.19 slightly ready

1.20-1.59 highly ready
0.80-1.19 ready
0.40-0.79 slightly ready
0.00-0.39 not ready
29. 23
For the general level of readiness, the scale below was used:
40.00-50.00 80%-100% very highly ready
30.00-39.99 60%-79.99% highly ready
20.00-29.99 40-59.99% fairly ready
10.00-19.99 20-39.99% slightly ready
0.00-9.99 0-19.99% not ready
For the strengths and weaknesses, an area was considered
strength if it got descriptive equivalent rating of highly ready and above;
otherwise, it was considered a weakness.
Parts of the Learning Activity Sheets
The learning activity sheets comprise of the rationale, the learning
objectives, the subject matter, the learning activities and sheets.
The learning activities are either with the help of the teacher or are
designed for independent learning.
Ethical Considerations
To establish and safeguard ethics in conducting this research, the
researchers strictly followed and obeyed the following:
The respondents’ names were not mentioned in any part of this
research. The respondents were not coerced just to answer the test.
30. 24
Proper document sourcing or referencing of materials was done to
ensure copyright.
A communication letter was presented to the registrar’s office to
ask authority to get the needed data on profile.
31. 25
CHAPTER III
RESULTS AND DISCUSSION
This chapter presents the data analysis and interpretation of the
gathered data.
Profile of the Students
The first problem of the study is on the profile of the students in
College Algebra.
Table 2 presents the profile of the students along sex, type of high
school graduated from and their high school final math grade. It shows
that out of 309 students, 161 or 52.10% are males while 148 or 47.90%
are females. This means that there are more male respondents than the
females. This is easy to understand since the courses which include
college algebra in their curriculum for the first semester are along
engineering, architecture, business administration and criminology.
Massey (2011) highlights that male students are more inclined to
enrolling to a course aligned to mathematics, engineering, architecture,
business management and criminal education. Registrar records as of
July 2013 also indicated that there were really more males than females.
32. 26
Further, out of 309 students, 125 or 40.45% graduated from
public schools while 184 or 59.55% graduated from private schools. This
means that majority of the students came from private schools in and

outside of La Union. This is because majority of the students came from
families that can afford education offered in the private schools. A
testament to this is their enrolment in SLC, a private HEI.
Lastly, it also shows the grade range of the students in their high
school mathematics subject. It reveals that 39 or 12.62% have grades
ranging from 75-78%, interpreted as poor performance, 106 or 34.30%
have grades ranging from 79-84%, interpreted as fair performance, 92 or
29.77% have grades ranging from 85-88%, interpreted as satisfactory
performance, 64 or 20.71% have grades ranging from 89-93%,
interpreted as very satisfactory performance and only 8 or 2. 59% have
grades ranging from 94-97, interpreted as outstanding performance. It
means that majority of the students had fair-satisfactory performance in
their high school mathematics. This points out to the fact that the
students had not fully mastered the desired learning competencies of
34. 28
Mathematics IV. The finding of the study jibes with Oredina (2011)
stating that students in College Algebra had not fully mastered the
competencies.
Level of Readiness in College Algebra
The second problem of the study is on the level of readiness of the
students in College Algebra.
Table 3 shows the level of readiness of students in College Algebra.
It is shown that the students have a mean score of 2.87 or 31.88% in
elementary topics, 3.70 or 52. 86% in special product patterns, 3.6 or
40% in factoring, 3.84 or 48% in rational expressions, 3.36 or 42% in
linear equations in one variable, 2.8 or 40% in systems of linear
Table 3. Readiness in College Algebra

equations and 1.13 or 56.50% in exponents and radicals. Thus, the
students were slightly ready in elementary concepts while ready in the
other remaining topics which include special products and factoring,
rational expressions, linear equations, systems of linear equations and
exponents and radicals. This means that the students were not so much
prepared to hurdle topics on sets, number line, operations on integers,
algebraic expressions and polynomials. Further, this means that the
students were prepared to apply special product and factoring patterns,
manipulate rational expressions, solve linear equations and systems and
deal with expressions involving exponents and radicals. However, since
36. 30
the rates of the mean scores are only between 30-57%, the students still
lack the necessary mastery to be able to hurdle the challenges of the
specified topics in College Algebra.
Generally, the students’ mean score is 21.3, equivalent to 42.60%,
interpreted as ready. Thus, students are generally ready for the course
content of College Algebra. They are familiar with the course contents
since majority of the contents of the course are just a review of high
school mathematics. However, it can be construed that students have
not really mastered well the competencies required in each topic.
Testament to this is the fair-poor performance of the students based on
their high school math grades.
This finding of the study corroborate with Kuiyuan (2009) stating
that the level of readiness of the students in College Algebra is at the
moderate level only. It was mentioned that students did not possess the
needed pre-requisite skills.
Correlation between Profile and Level of Readiness
The third problem of the study is on the significant relationship
between the profile and the level of readiness of the students.
Table 4 shows the relationship between profile and the level of
readiness of the students. It shows that the correlation coefficient
between sex and the level of readiness is 0.18, interpreted as negligible

correlation. This negligible correlation is significant at 0.05 level of
significance. This signifies that sex does not significantly affect the level
of readiness and vice versa. Thus, sex does not determine the level of
readiness in college algebra.
Further, it also shows that the correlation coefficient between type
of high school graduated from and the level of readiness is 0.05. This
negligible correlation is significant at 0.05 level of significance. This
denotes that the type of high school graduated from does not
significantly affect the level of readiness and vice versa. Thus, the type of
38. 32
high school graduated from does not necessarily determine the level of
readiness. This is true since schools, regardless of type, offer the same
curriculum provided by the Department of Education, hence, the
students still learned the same content in their secondary schools.
Moreover, it also divulges that the correlation coefficient between
high school math grade and level of readiness in College Algebra is 0.63.
This marked correlation is significant at 0.05 level of significance. This
means that high school math grades significantly affect the level of
readiness. This means that the high school mathematics performance of
students affect their level of readiness in College. This is easy to
understand since the high school mathematics subjects provide solid
foundation for students to hurdle the course contents of College Algebra,
especially so that the contents of the course are review of the high school
topics. This finding of the study corroborates with the study of Kuiyuan
(2009) stating that high school GPA strongly correlates to college
readiness.
This finding run parallel to the study of Kuiyuan (2009) revealing
that high school and college GPA had strong correlation with the
students’ level of readiness in College Algebra, while the other factors
such as national exam scores, type of school graduated from had weak
correlations.
39. 33
Comparison on the Level of Readiness of the Students in the
Three Colleges
The fourth problem of the study is the significant difference
between the level of readiness of the students in the three colleges,
CASTE-IT-CRIM, CCSA, and CEA.
Table 5. Comparison on the Level of Readiness

Table 5 reveals the comparison of the level of readiness of students
in the three (3) departments of SLC, the CASTE-IT-CRIM, the CCSA, and
40. 34
the CEA. It shows that the comparison on the level of readiness of
students from CASTE-IT-CRIM and CCSA has a computed t-value of
1.80. This is not significant at 0.05 level of significance since the p-value
is larger than 0.05. Thus, it can be inferred that the mean difference of
2.173 is not significant. This denotes that there is no significant
difference in the performance of the students in the CASTE-IT-CRIM and
the CCSA. Thus, it is safe to construe that students in CASTE-IT-CRIM
are not better than CCSA students, and vice versa. This finding runs
parallel to the hypothesis of the study that there is no significant
difference in the performance of the students in the two identified
departments.
Further, it shows that the comparison on the level of readiness of
students from CASTE-IT-CRIM and CEA has a computed t-value of 3.09.
This is significant at 0.05 level of significance since the p-value is smaller
than 0.05. Thus, it can be inferred that the mean difference of 3.82 is
significant. This denotes that there is a significant difference in the
performance of the students in the CASTE-IT-CRIM and the CEA. This
finding does not run parallel to the hypothesis of the study that there is
no significant difference in the performance of the students in the two
identified departments. Thus, students in CEA are better in College
Algebra than the students in CASTE-IT-CRIM. This is easy to understand
41. 35
since students enrolled in engineering and architecture courses are
inclined to mathematics.
It also shows that the comparison on the level of readiness of
students from CCSA and CEA has a computed t-value of 1.43. This is not
significant at 0.05 level of significance since the p-value is larger than
0.05. Thus, it can be inferred that the mean difference of 1.64 is not
significant. This denotes that there is no significant difference in the
performance of the students in the CCSA and the CEA. This means that
students CSA are not better in College Algebra than students in the CEA,
and vice versa. This finding runs parallel to the hypothesis of the study
that there is no significant difference in the performance of the students
in the two identified departments.
Strengths and Weaknesses in the Level of Readiness in College
Algebra
The fifth problem of the study is the strengths and weaknesses in
the level of readiness of the college students.
Table 6 shows the strengths and weaknesses of the students in
College Algebra as culled out from their level of readiness. It can be seen
from the table that all the content areas under College Algebra are
considered as weaknesses of the students. This means that the students
are not that prepared in taking the subject. This implies that they did not
42. 36
possess yet the needed skills needed to hurdle the demands of the
course.
This finding of the study harmonizes with the study of Leongson
(2001) that students’ performance in College Algebra is alarming. It was
mentioned that the students were at the poor-fair levels only.
This finding also corroborates with the study of Ragma (2014)
revealing that all content areas in College Algebra are found to be
constraints. He explained that the students were not able to successfully
imbibe the skills in algebraic concepts and manipulations.

Recommendations
Based on the conclusions of the study, the researcher recommends
the following:
1. The learning activity sheets should be adopted by mathematics
instructors.
2. The readiness test used in this research should be utilized as a
diagnostic tool by all College Algebra instructors before starting the
formal lessons every start of the school year.
3. Students who wish to enroll in mathematically-inclined subjects
should be really good in mathematics.
4. A future study looking into the effectiveness of the learning activity
should should be conducted.
