Abstract:
The purpose of this researchis to provide better understanding to
representelectric circuits using various symbols and for various
conditions. This has been done through variety of teaching methods like
discussion, demonstrationmethod, heuristic method, inquiry method,
remedial teaching and use of ICT Toollike showing videos and
PowerPointpresentation. Upon completion of the researchwe found
that students were facing problems because they were not able to
practically representit due to lack of practice.
Introduction:
I found that students are having difficulties in understanding technical
concepts ofelectricity viz; where to attach the different components of the
electric circuit . This is because theyhave not understood the concepts
clearly. Severalchallenges were there to find solutions for making the
concepts clear. Scienceis a dynamic, expanding body of knowledge. It is
common knowledge that exceptfew, hardly does any Science teacher
encouragesa student to go beyond the contentand concepts given in the
textbook. This is making the subject boring and dull. To overcome the
boredom & dullness of the concerned topic i. e electricity. I was supposed
to adopt a suitable methodology. Although I have to make a choice for a
method which is economicallyconvenient for me to conduct within the
classroom. So I decidedthat I will be executing some experimental
investigations with the help of some articles used frequently in our daily
lives. Also I used the technologybasedstrategyas students candevelop the
understanding about electricity by visualizing the conceptwhich would
6. 6
help them to retain the concepts in their mind. Some important concepts to
be taught to them in this context were,
� It is convenient to represent electric components by symbols. Using
these,
an electric circuit canbe representedby a circuit diagram.
� When an electric current flows through a wire, the wire gets heated. It is
the heating effect of current. This effecthas many applications.
� Wires made from some specialmaterials melt quickly and break when
large electric currents are passedthrough them. These materials are
used for making electric fuses which prevent fires and damage to electric
appliances.
� When an electric current flows through a wire, it behaves like a magnet.
� A current carrying coil of an insulated wire wrapped around a piece of
iron is calledan electromagnet.
� Electromagnets are usedin many devices.
Now the question arises is why student of sevenstandards don’t know this
ground level basics? Is problem lies in teaching methods adopted by
previous teachers? Is teachernot able to deliver the information
effectively? Is there lack of interest from students or from teacher? Oris
the contenttoo high as per the age level?
To be clearer, some researchhas been done to know whether there is any
difference betweenIndian education curriculum and international
curriculum or not. This researchwas able to answerthe question : ―Is
really this content too high for sevenstandard children?‖ And
surprisingly we found that in Indian curriculum the most of the content
that is included in seven standard, that in international curriculum were
taught in fifth standard only.
Basedon some backgroundliterature, three possible reasons canbe
7. 7
suggestedthat might be making this contentdifficult. First, it’s hard
because ofnature of discipline- its characteristic,how it relates to other
field, how it is studied. Second, the ways the content is taught can make it
difficult. And finally, what student students bring to learning the content,
including prerequisite backgroundknowledge, relevantexperiences,
attitude about learning in generaland beliefs about themselves as learners,
can make learning something difficult.
After finding the diseases,now it’s the turn of the remedy: what helps
students overcome the difficult aspects oflearning this content? How
can I make this contenteasyto students? How can I make this content
interesting so that it engagesstudent’s brain?
There are various teaching methods that can be used by prior researchers
like discussionmethod, demonstration method, project-basedmethod,
heuristic method, inquiry method, remedial teaching method, ICT
learning etc. Evidence from a number of disciplines suggests thatoral
presentations to large groups of passive students contribute very little to
real learning. In physics, standard lectures do not help most students
develop conceptualunderstanding of fundamental processesin electricity
and in mechanics (Arons, 1983;McDermottand Shaffer, 1992;
McDermottet al., 1994).
Although many of the methods mentioned in above are consistentwith
what experts know about how students learn, they may not be welcomed
by all of the students in a class. There are severalways to help students
make the transition from passive listeners to active participants in their
own learning (Orzechowksi, 1995)
8. 8
Becausethe compositions oftoday’s classroomare arguably the most
diverse as they ever have been, either choice ofdifficulty leaves a number
of students disengagedwith the lessonpresented. In his ground-breaking
work on flow, researcherMihaly Csikszentmhalyidescribedflow state in
the following graphic Figure1 (Hunicke & Chapman, 2005). Froma
pedagogicalperspective, whenthe challenge of the assignedtask is higher
than the skilllevel of the student, the student will experience increased
levels of frustration and ultimately disengagement. Conversely, if a
student’s assignedwork is substantially below his or her ability, boredom
and again, disengagementwill occur.
A researchprojecttitled ―What Did You Do in SchoolToday?‖ examined
the engagementlevels of Canadian secondarystudents. The central
premise of the researchconductedwas that student engagementis key to
greaterachievementin their education and that all students need to receive
effective and intellectually challenging materials to complete in the
classroom(Levin, 2010). The study found that overall levels of socialand
academic engagementin secondaryschoolsare low, and levels of student
engagementdecline steadily throughout middle and secondaryschool
grades and that many students had a low levels of interest and generally
9. 9
were unsure of the relevance of assignedschoolwork in language arts and
mathematics (Willms, Friesen& Milton, 2009). While many of us in
educationstate that we want students to become lifelong learners, the lack
of engagementfound in today’s high schoolstudents is alarming.

Research setting:
Method to find out problematic topics
I implemented survey method to identify the difficult topics which need action research
to be done. I circulate a form in the class where they have to write difficult chapter and
the specific topic of that chapter. Students had different opinion. I got 4 majority topics
in which they find most difficult. Around 80% students mentioned the topic as
representation of electrical circuits (using various symbols). So finally with help of
consensus the topic was decided.
Then the question was in electric current and its effects what the difficult part was.
Each student one by one was askedabout the difficulty in chapter so majority of them
had difficulty in representing or expressing circuit diagram for various conditions
given.
The experimental investigations involved the students to perform the activity & to find
the result for the investigation on their own without traditional method of teacher
centered teaching. To promote a better understanding amongst the students such hands
on experimental investigation is effective which made me use & implement this method.
Also questionnaire were used to measure the knowledge & attitude of learners.
The experimental investigation on electricity ( electric circuit diagrams emphasised
more on symbols ) comprised of following: The requisition of the investigation will be
brought up by students itself on prior announcement of the teacher. Teacher will ask
the group of students so formed to perform the experimental investigations.
Preparationof plan
Finally the floor plan was prepared from my end as follows-:
I will first clear the basics about light through remedial teaching method and
demonstration method. Then I had made them perform the following activity in class.
11. 11
TITLE: DEMONSTRATION OF ELECTRIC CIRCUIT DIAGRAMS
1. Hands on experiment on how to make the circuit diagrams
You will need: A bulb, wire, cell or a battery, switch , conductors and insulators
What to do:
1. Join all the components correctly.
2. Observe the bulb when switch is on and when switch is off.
3. Draw the same circuit on paper using symbols of the same .
Then the next step that I had taken was to provide them with a pamphlet consisting of
various symbols used for different electric components which was as follow:
12. 12
Circuit Components Table:
Then I took viva of students and found that just merely showing teaching aids and
experiments does not ensure understanding and remembering. So I decided to show
them a PowerPoint presentation and a video explaining how electric circuits works and
the flow of current in the circuit with its direction.
SHOWN VIDEO ON WORKING OF ELECTRIC CIRCUIT DIAGRAMS, HOW THE
CURRENT FLOWS. ( TECHNOLOGY BASED )
Instrument –laptop and a projector
You will need: 1-2 Videos on working of circuit diagrams for better understanding.
What to do:
1. Set the video on the projector and make the students sit quietly so that they can
view the video with full concentration

This research study aimed at identifying the impact of remedial teaching on improving
the competencies oflow achieving students in Mannar district of Sri Lanka. For this
purpose, ninety seven students from rural and urban area were selected from four
different schools in Mannar Education Zone. The selection ofthe primary grade is
decided to ensure the effectiveness ofthe program in primary education.
Objectives of this program are to investigate the reasons for the low achievement
of students in this zone, to assess the effectiveness of the remedial teaching and to
recommend possible actions to be carried out for improvement. The data were
collected by interviewing relevant authorities and from the secondary records.
Findings show that the socio economic condition of the family and physical and
psycho social status of the student cause low achievement.
The implemented remedial program proved to be effective with recovering ninety four
percentages of students in Tamil Language and ninety three percentages of students in
Mathematics. Continuous capacity development of teachers on concept and skills of
remedial teaching and strengthening the Referral mechanism to find solution for the
socio economic and psycho social reasons to ensure the sustainability of the recovery
are strongly recommended.

Title: Implication of Technology in the Classroom
About the author: Jeff Brown, S. Ojara, G. Kimbugwe, A. P. Adrawa, December 8,2010
The author talks about impact of technology on brain and how it helps in learning. The
first area of research investigated will be the impact that technology use has on the
brain. In order to cope in the often-overwhelming online environment, we have adopted
strategies of multi-tasking and power skimming to process such a high flow of
information. A recent series of articles in the New York Times discussing the impacts
that multi-tasking while using technology has on the physiological operations of the
brain gives us a glimpse of what impact these choices have on brain function. Scientists
have found that multitasking while on Internet connected devices undermines our
ability to focus (Richtel, 2010) because we are consistently bombarded with new emails,
Facebook updates, and Twitter posts.
According to the research done by Jeff Brown:-
54% of 21st century kids start using mobile devices when they are 5 to 8 years old.
30% of the apps on parents’ mobile are downloaded specially for their children’s usage.
77% of the parents accept that usage of tablet increases children’s learning & creativity.
72% of iTunes top selling apps are designed for pre-schoolers and elementary students.
By observing these statistics, we can easily estimate how greatly technology influences
elementary education. Educational Technology includes all the approaches of
technology that are utilized to enhance learning. The axiom ―beauty is in the eye of
the beholder‖ applies to technology use in the schools.

content so easy and effective to the participants that they no more have any
difficulties regarding to this chapter.
Demonstration of certain experiment like formation of electric circuit on my own in
front of them using conducting wires, bulb and battery. Given them a pamphlet
consisting a table consisting of various symbols used foe electrical components. Shown
them an activity to show flow of electric current. Taught them heating and lightening
effect of electric current using the teaching aids made in class(circuit). Video was also
shown to enhance their understanding related to the concept.
To be more effective we take the help of technology by showing PowerPoint
presentation and video that make eternal impression on student’s brain.

Data collection tools:
We have taken oral interviews as well as a Survey. Interview and survey was taken to
find difficult area in their preferred topic. We have also taken oral conventional class
test as Pre-test to know their level of difficulties and to find their misconception about
the topic. At the end Post-test has been conducted to confirm their understanding
after applying appropriate strategies.
Process of data collection:
The first phase of the project involves a screening interview of students that has been
done through survey form and also through oral discussion in the class. Further to be
more specific a pre-test of 25 minutes has been conducted. After strategizing and
17. 17
implementing appropriate solution a post-test has been conducted to determine success
or failure of actions.
Analysis of Data:
Analysis of survey:-
Taken to analyze difficult topic that student want to learn again. Results says 80% of
students have difficulty in electric current and its effects chapter, about 12% have
trouble in Acid and Base chapter, 7% in Reproduction and 1% of students are
facing problem in motion chapter. This result clearly indicate the most problematic
chapter that students wants to learn again.

Research findings:
After action is taken 78% of students in class score more than 50% in the
test, i.e. maximum numbers of students have concept clarity.
Students score more in post-test as compared to pre test.
Only 26% students were able to draw the ray diagrams , but after action is taken i.e.
when students are made to sit and draw on paper in class and it is related
with puzzle then 89% students draw and label the ray diagram.
86% of students were able to explain the use of a particular mirror or lrns in a
particular instrument. So collectively it is found that majority had improvement
in performance after action plan was implemented
Conclusion:
Children remember the concept of circuit formation using various symbols for electric
components; the technology helped me to make them remember diagrams. Remedial
teaching and demonstration method plays a key role in the whole study. Showing video
to children helped a lot to make them understand the chapter. Use of Teaching aids
was fruitful.
