COMPUTER ASSISTED INSTRUCTION IN CHEMISTRY IN RELATION TO LEARNERS’ PERSONALITY Dr.R.Sivakumar
Abstract
The aim of this study was to find out the effectiveness of Computer Assisted Instruction in Teaching Chemistry In Relation To Learners’ Personality. The sample consisted of 40 students in Control group and 40 students in Experimental group. The data were collected using appropriate tools and it was analyzed by t’ and F’ test. The finding is that the achievement scores of Experimental group Students were higher than the Control group Students. Introduction

Today is an era of Computer. Computer finds a big place in educational technology. Many research studies proved CAI has been effective in realizing the instructional objectives. But there is dearth of studies in establishing relative effectiveness among different modes of computer based instruction. The studies have also proved the effectiveness of different media changes with respect to individual differences among learners. Under this circumstance it is inoperative to establish whether the personality of learners has any influence in determining the media effectiveness. The investigator has thus chosen computer as the medium to teach Chemistry. The Investigator has also measured the effectiveness of teaching Chemistry through computer over the conventional method namely lecturing 2

Computer Assisted Instruction
The most exciting innovation in the Educational Technology is Computer Assisted Instruction. It is a development of systematic programmed learning and teaching machine. It is a self-instructional device with the principle of atomization. Computer Assisted Instruction as “Computer applications applied to traditional teaching methods such as drill, tutorial, demonstration, simulation and instructional games”. It is an effective media and an indispensable aid in the teaching-learning process. The instructional process carried out with the help of computer is known as Computer Assisted Instruction. It is not merely a sophisticated type of programmed instruction but a different kind of instruction altogether. It uses programmed instruction electronic data processing, data communication, concepts of audio-visual and media theory, communication theory, system theory and learning theory. Computer technology is likely to influence education enormously and can play an important role in enhancing the efficiency of the teaching-learning process. C.A.I. is perhaps the best, because it offers:  Individualized instruction

 Effective interaction with the learner and
 Immediate feed back
Science
In common usage, the word science is applied to a variety of disciplines or intellectual activities, which have certain features in common. Usually a science is characterized by the possibility of making precise statements, which are susceptible 3

of some sort of check or proof. This often implies that the situations with which the special science is concerned can be made to recur in order to submit themselves of check, although this is by no means always the case. There is observational science such as astronomy or geology in which repetition of situation at will is intrinsically impossible, and the possible precision is limited to precision of description. Science Education

It we throw a bridge between science and education, using psychology, we arrive at the concept of science education, which bluntly speaking, is an integrated concept. If so it is then, within the realm of possibility to link the most powerful concepts of science to the growing minds of children through active experimental pedagogy. In that case, science education need no longer remain a single dimension activity. It would be our job then to develop the scientific and technical capabilities of our school going pupils. We may be then able to win our race in education in the 21st century. The field of science education is thus coterminous with life. This view promotes as well the inherent value system...
