Department of Physics, Dhing College, Dhing, Nagaon, AssamAbstract:. Young children have curiosity about the conductor is also associated with a magnetic field,phenomena taking place around them and which is used in electrical bells.teachers have the responsibility to create an The elementary school years especially areenvironment so that a positive attitude grows up important because this is the time in which childrenamong the pupils in their early stage of learning. develop a foundation of science for entire life. So itSince electrical energy is the basic need of is very important to guide them carefully. Electricitymodern age, students must have to enhance in primary classes is the basic of science. If thestorehouse of knowledge about electricity. status of science education is to changed then theTherefore in order to make teaching electricity education of teachers who have the responsibility foreffective & yet interesting, several techniques teaching those children will be a critical factor.may have to be adopted. Elementary school teachers were far more sanguine about their working conditions, when compared toIntroduction their middle and high school counterparts and The importance of science education in the Teachers who report relatively low levels ofearly childhood / elementary years is very important satisfaction with their professional developmentif we are to expect the young people of this nation to often do not have access to the kinds of training theybecome active & interested in science and believe they need. Teacher must have sufficienttechnology. The school years are very important content knowledge and skill in different teachingbecause it is this precious years children develop a techniques, an ability to evaluate and use appropriatefoundation of science. Here the prime responsibility tools to supplement the text. In elementary, middleof the teachers is to make science interesting to the and secondary school education, the study suggestsstudents from the early years of schooling. These that the activity of story telling has an impact onskills are required for processing information in to a Participants interpersonal relationships, empathy,developing system of knowledge. and senseof“Connectedness" in the classroom and It is here that an assessment needs to be built teacher-student friendly relation regardingdone regarding the effectiveness of teaching education and knowledge. Teachers who intend toprocedure, additional requirements of the school leave their schools and teaching are more likely tochildren and the teachers and the reforms that are have grave concerns about their lack ofneeded to make science an enjoyable learning empowerment, poor school leadership, and the lowsubject. levels of trust and respect inside their buildings (Barnett Berry, Mark Smylie & Ed Fuller,ELECTRICITY-AN INTRODUCTION: November 2008).

While testing the basicknowledge of the students questions were asked Conclusion and Recommendations:from the questionnaire, It was found that 48% During our project period, our team wantedcorrect answers was given by the students, which to visit 6 schools in Batadrava Block. But, due towere very basic. Al most 70% of the students have time constrain, it was not possible to collect datanot been handled electrical devices although the from all schools.

The learning abilities (i) Although the phenomenon of electricity isof the students to a large extent are dependent upon very interesting but students are not eager enough tothe way the teacher is able to make his /her views learn because the teaching-learning process ismore easily acceptable as well as interesting. examination oriented. The tests of students revealedTeaching electricity is never very easy since it that they are not able to answer basic questions.

It may be noted that the necessary battery, wires, ammeter, voltmeter etc. the topicfurniture‟s, laboratory facilities are very essential for seems to be very easy to learn. But there are fewteaching and learning. Since the schools do not have schools which provide such equipments.laboratory facilities with Laboratory equipments, it iii) This may suggest that not all teachers areis not possible to impart “practical base knowledge confident in their ability to use available laboratoryin electricity” to the students. They just go through equipment. The survey administered to seventy-ninethe usual process i.e. black board and text book, thus science teachers asked if they are comfortable usingmaking the learning process monotonous which is the following: microscopes, Bunsen burners,also reflected in the survey which shows that 55% of balances, thermometers, autoclaves.

Therefore at least 30% of AUTHORS the annual marks must be based on student First Author–Debabrata Debnath, M.Sc. activity in laboratory, project work, Associate Professor, Dhing College, participation in science exhibition etc. Dhing,Nagaon,Assam.  The quality of text book needs to be looked Second Author- Rabindra Sarmah Baruah, into especially paper quality, illustrations, M.Sc. Associate Professor, Dhing College, ray diagrams, definitions etc. The text book Dhing,Nagaon,Assam. needs to be scientifically and professionally reviewed.  The other important basic needs of schools are – Drinking water facility Ideal teacher- student ratio Class room infrastructure and desk- bench Well equipped laboratory facility Power supply in class room  Other issues, directly related to science teaching process – (a) Mandatory participation of the students in different projects, science exhibition etc. (b) Establishment of periodic and compulsory feedback mechanism by the students about teaching methods. (c) Organizing regular science quiz, preparation and handling electric circuit and devices and science related tours to create interest in science. (d) Publication of annual school science magazine with the involvement of students will help create an interesting learning environment. (e) For nightly holding a “Science awareness day and exhibition”.Final Word: Teaching electricity in primary classes withthe usual & monotonous way of teaching is of nohelp. The simplest way of teaching is thedemonstration of electrical phenomenon with thehelp of lab equipment‟s and electrical devices.REFERENCES 1.
