A Comparative Study of two ways specifically construct Mapping & Lecture technique on learning ideas

Introduction

Bluetooth technology in computers and WAP (Wireless Application Protocol) in physical science and human ordination in life science square measure simply a couple of of the many advances that have taken place recently.

These advances indicate that science plays a significant role in fashionable society. Thence it becomes essential for the science specializer to reinforce purposeful learning, as today's student’s square measure future architects of contemporary society. Thence the investigator has adopted construct mapping in concert of the ways to introduce the ideas Semiconductor Heterostructures, IC that honour has been awarded throughout the year 2000.

Concept Map

A Concept Map could be a schematic device for representing a group of construct meanings embedded during a framework of propositions. During a construct Map, the lot of general, a lot of inclusive ideas ought to be at the apex of the construct Map, with {progressively|increasingly|more and a lot of} more specific, less inclusive ideas organized below them. Since the ideas square measure organized hierarchically, purposeful learning precedes a lot of simply as new ideas or construct meanings square measure subsumed below broader a lot of inclusive ideas.

Present Study

In the gift study the investigator introduced the two ideas specifically Semiconductor Heterostructures, IC through 2 completely different strategies specifically construct Mapping technique and Lecture technique. The XIm commonplace students of N.K.T.National Girls' Higher Gymnasium, Republic of India (where the investigator is working) learning below State Board programme fashioned the sample. The category was divided into 2 teams of twenty students every and was treated as management cluster (CG) and Experimental cluster (EG). Two B.Ed. trainees (K.R.Kavitha and N.V.Jaya Bharathi) of N.K.T.National faculty of Education carried the experimental a part of the analysis studydeveloped by the investigator. Ms N.V.Jayabharathi instructed the 2 ideas to manage cluster through Lecture technique whereas Ms.K.R.Kavitha instructed a similar ideas to Experimental cluster at a similar time through construct Mapping technique.

Objectives of the Study

1.To find the effectiveness of construct Mapping strategy over Lecture technique on accomplishment in Physics of XI commonplace students.

2.To study the impact of Scientific perspective on accomplishment in Physics of scholars learning through Lecture technique.

3. to check the impact of Scientific perspective on accomplishment inPhysics of scholars learning through construct Mapping technique.

Data assortment

A pre-test was administered for each the teams to assess the

students' initial information. Then the 2 ideas were

introduced by 2 completely different strategies to individual teams. Finally

a post-test was administered to each the teams. The

Experimental style, that is pre-test- treatment - post-test is

shown in Table one

The two B.Ed. trainees carried the analysis programme

simultaneously at a similar time and got one hour to

complete the programme. By cooccurring implementation of the

programme any error thanks to fatigue etc is neglected. A Science

Attitude Scale developed by Dr. Mrs. Avinash Grewal was additionally

administered at the tip of the session.

Achievement take a look at

The accomplishment take a look at consisting of twenty five multiple-choice queries

was developed by the investigator and every question carries one

mark. The accomplishment take a look at served as each pre-test and

post-test. The investigator utilised the Scientific perspective

Scale (SAS) developed by Dr. Mrs. Avinash Grewal to see

the attitudes of XI commonplace students collaborating within the

research programme. The Science perspective Scale (SAS) consisted

of twenty things wherever ten positive things (S.No

2,4,6,8,10,12,14,16,18,20) and ten negative things (S.No.

1,3,5,7,9,11,13,15,17,19) square measure gift.

Scoring

Each of the ten positive things on the dimensions is allotted a weight

ranging from four (strongly agree ) to zero (strongly disagree). In

the case of ten negative things the dimensions evaluation is reversed

ranging from zero (strongly agree) to 4(strongly disagree). The

attitude score of a subject matter is that the assemblage of scores all told

twenty things within the scale. therefore a most of eighty scores will

be obtained by the topic.

Concept Maps

Seven construct Maps referring to the two ideas below

consideration were developed by the investigator.

Lesson arrange

A Lesson arrange consistent with that the ideas were introduced by

Lecture technique was additionally developed by the investigator.

Data Analysis

The analysis was performed by teaching the 2 ideas to 2

groups specifically management cluster (CG) and Experimental cluster (EG)

through Lecture technique and construct Mapping technique. Before

commencing the lesson the pre-test was given and once the

lesson was instructed the post-test was once more administered.

The Gain Score of Lecture technique is given by GL = LPO - LPR

where GL is gain score of Lecture technique LPO is post-test score

of Lecture technique LPR is pre-test score of Lecture technique

The Gain Score of construct Mapping technique is given by gigacycle per second = CPO - kiss of life

where gigacycle per second is gain score of construct Mapping technique CPO is

post-test score of construct Mapping technique kiss of life is pre-test score

of construct Mapping technique

Analysis of essential Ratios

Critical Ratios were calculated to check the importance of

difference between the pre-test and post-test scores in Lecture

Method and construct Mapping technique.

Critical magnitude relation between the

pre-test and post-test scores in Lecture technique

The essential magnitude relation calculated in respect of pre-test and

post-test several management cluster instructed by Lecture technique is

The results of Table two indicate that there's important

difference between the post-test and pre-test several students

of management cluster instructed by Lecture technique. Since the post-test

score is bigger than the pre-test score we are able to conclude that

the performance of scholars is considerably above their

performance in pre-test.

The results of Table three indicate that there's important

difference between the post-test and pre-test several students

of Experimental cluster instructed by construct Mapping technique. Since

the post-test score is bigger than the pre-test score, we can

conclude that the performance of scholars in post-test is

significantly above their performance in pre-test.
