The prime concern of the study is to determine the impact of visual aids on the academic achievement of 7th Grade learner .The design of the study is definitely a type of experimental design, it is mainly of non-equivalent control group design of the Quasi experimental type(as it is not possible to have two absolutely equivalently schools) which is employed to study the impact of visual aids on the academic achievement and achievement motivation of 7th grade learners. The sample of the present study comprised of 78 students of 7th class from two schools namely, Govt. Senior Secondary School, Panjgain and Govt. Senior Secondary School, Barmana as the control group and experimental group respectively and 34 students were assigned to each group. The experiment was conducted for 30 days by using visual aids to the traditional method of teaching. The parallel form of achievement tests (Form A and Form B) prepared by the investigator was used. In the present study the obtained (t=3.81) which is greater then the expected 2.72 at 0.01 level of significance so it is concluded that teaching through visual aids had significant impact on the academic achievement.
KEY WORDS: Visual aids, Academic Achievement
We live in an unusual world marked by great and rapid changes. Since the appearance of man on
this planet, thousand of years rolled by silently before any technological discovery could be made. With an abrupt increase in the number of teachers and learners, the educational pattern of the country has changed immensely and the ineffectiveness of traditional method to meet the growing demands in the field of education there is a great need for novel methods and ways for providing instructions by the well wishers of educational field. The use of visual instruction provides enrichment of education and learning through maximum use of sense of sight. Visual aids means those sources in which only visual organs are used or applied that is knowledge is mainly achieved through visual organs that helps to make teaching and learning more interesting, more stimulating, more reinforcing and more effective.
- The visual aids are potent starters and motivators.
- The visual aids help the pupil in making association and recalling ideas.
- The visual aids should be meaningful purposeful and accurate in every aspect.
- The visual aids help in classifying various points and concepts.
- They help to reduce the verbalism.
- Visual aids contribute to increase retentively as they stimulate response of the whole organism to the situation in which learning takes place.
The dictionary meaning of ‘achievement’ is to ‘accomplish’ or to bring successful issue. In the present study the word achievement has also been used with the same meaning i.e. something achieved by the students through class room teaching. Academic achievement is the amount of knowledge derived for learning, in an educational institution. Any behavior that is learned may come with in the scope of achievement. Academic achievement has found to be related to the acquisition of principles and generalization and also the capacity to perform efficiently certain manipulations of objects, symbols and ideas. Learned and Wood (1938) concluded based on their study that education was unavoidably intellectual in which knowledge was the dominating feature of educational outcomes.

REVIEW OF RELATED LITERATURE
Lock and garden (1945) reported that the percentage of usable films for primary elementary and junior high schools and senior schools, college and adult grades were 42%, 20.8%, 62.9%, 81% and 71.7% respectively. Dale (1969) pointed out that the audio-visual aids can generally improve teaching. Dawyer, Francis, M (1975) found the use visualization to complement programmed instruction is an effective instructional technique. Anderson, R.B (1994) concluded that both the visual information and verbal information improved recall of non essential information struction is an effective instructional
RATIONALE OF THE STUDY
The present study the attempt has been made to study the impact of visual aids on academic achievement and achievement motivation. The use of visual aids helps in the enhancement of the achievement level and motivation level of the learners thus, this work assumes more significance. This study will also help to raise the use of visual aids at lower level of learning. Students at lower level are more interested and feel motivated to learn by seeing then by the use of traditional methods of teaching the use of visual aids will positively affect their future thinking toward the scientific knowledge and this will help in increasing the perceptual thinking and enhancement. According to psychologist, the simplest type of learning is the formation and development of perceptual process. The stimulation of sense organs on path are logically and genetically the beginning of learning process. Such stimulation leads to the organization of the perceptual experience. Perceptual development demands the careful analysis of objects into their elements through observation and the fusion, of there elements into whole which can be achieved by the visual aids.
OBJECTIVE OF THE STUDY
- To develop the instructional visual aids for teaching science to the students of class 7th.
- To assess to the impact of visual aids on the achievements in science of class 7th
- To assess the differential impact of visual aids on the academic achievements of boys and girls of 7th
H1 There is no Significant difference on Academic Achievement scores of control and
experimental group at pre test.
H2 There is no significant difference between pre-test and post-test scores on academic
achievement of boys and girls of control group.
H3 There is no significant difference on academic achievement between boys and girls of
H4 There is no Significant difference on academic achievement scores of the control and
experimental groups at post –test.
H5 There is no Significant difference between pre-test and post-test on academic
achievement of both the control and experimental groups.
DESIGN OF THE STUDY
The prime concern of the study is to determine the impact of visual aids on the academic achievement of the 7th Grade learner .The design of the study is definitely a type of experimental design, it is mainly of non-equivalent control group design of the Quasi experimental type (as it is not possible to have two absolutely equivalently schools) which is employed to study the impact of visual aids on the academic achievement.
Sample of 68 students of 7th class of Govt. senior secondary school of Panjgain and govt. senior secondary school of Barmana were taken in the present study . The 34 students of 7th class of Govt. senior secondary school of Panjgain were taken as control group. They were only exposed to the traditional lecturing- based teaching of science by their regular teachers only and The 34 students of 7th class of govt. senior secondary school of Barmana were taken as experimental group. In the present study, teaching through visual aids is the treatment given to the experimental group.
- Researcher used self made Questionnaire for Achievement Test.
It may be interpretive that the initial mean difference that exists between the control and experimental groups with regard to academic achievement is not significant as such both the groups may be considered to have almost equal level of academic achievement. In other words both the groups may be considered to be equivalent so far as their academic achievement is considered.
Therefore, it may be interpreted that the significance of difference between pre as well as post test scores of boys and girls of the control group are not significant .As such it may be concluded that the mean scores of boys and girls of control group do not vary on academic achievement .In this context, the hypothesis H3 that is, the boys and girls of class 7th do not differ significant on a academic achievement may be rejected.
Therefore, from the result it may be interpreted that the difference between boys and girls of experimental group on academic achievement is not significant. As such, both the boys and girls of the experimental group may be considered to have almost equal level of academic achievement. As such, the hypothesis that is the boys and girls of 7th class of experimental group differ significantly on academic achievement may be accepted.
Means, S.D and t-ratios for post-test of academic achievement scores of control and Therefore, it may be interpreted that the difference that exists between the control and experimental groups with regard to academic achievement is significant .As such, both the groups may not be considered to have equal level of academic achievement and since the , mean scores of experimental group is higher than the control group, it may be concluded that the subjects of experimental group do better under the experimental treatment.
Therefore, it may be concluded that the difference between the said mean scores of the control group is significant. In other words it may be concluded that teaching through traditional method had significant impact on academic achievement of 7th grade learners.
On the contrary, the study of significant of difference between the pre and post test mean scores of the experimental group on the variable academic achievement as presented in table 5 give at t value of 3.81 it may be mentioned here that the critical values of t ratios to be significant at 0.05 and 0.01 levels of significance need to be 2.03 and 2.72 respectively with 33 degrees of freedom.
In the present case since the obtained t value of 3.81 is greater than the expected 2.72, at
0.01 level of significance, it may be concluded that there exists significant difference between the pretest and posttest scores of the subjects of experimental groups. On the basis of the result the investigator feels to conclude that the teaching through visual aids had also significant impact on academic achievement of the learners. However, a close look on the mean scores of the control and experimental group reveals that teaching through visual aids is found to be more influential in comparison to the traditional method of teaching.
Findings of the study
The major findings of the study are presented briefly as follows,
- The use of visual aids was found to be effective in enhancing the academic achievement.
- The traditional method of teaching was found to be useful in enhancing the academic achievement of the learners.
- The use of visual aids was found to be more effective than the traditional method of teaching in enhancing the academic achievement of the learners.
- The use of visual aids in teaching process found to be effective in enhancing the achievement of learners in science.
It may be concluded that use of visual aids in teaching has significant importance in enhancing academic achievement among seventh class learners. Teaching through visual aids is more effective for the development of academic achievement traditional lecturing method .It also shows that it is one of the potent way of imparting science education and communicating science and technological advancement in the integrated and holistic manner, Hence special emphasis should be given for the use of visual aids in science education.
