A study on level of Teacher Effectiveness of Secondary Schools Science Teachers

: This study was designed to study the level of Teacher Effectiveness of Secondary School Science Teachers. Samples of 610 Science teachers were selected from 360 schools of Mandya district in Karnataka. Descriptive statistics, t-test, one way ANOVA and TUKEY’s HSD post hoc procedures were used for statistical analysis. This study reflects that, 15.08% of Secondary School Science Teachers showed high Teacher Effectiveness. 66.88% of Secondary School Science Teacher showed medium Teacher Effectiveness and 18.3% of Science Teachers of Secondary Schools showed low Teacher Effectiveness. There exists no significant difference between Male and Female Physical Science and Biological Science Teachers with respect to Teacher Effectiveness. It was found that there was significant difference between the Junior and Senior Science Teachers of Secondary School with respect to Teacher Effectiveness. This study also revealed that there was significant difference between Government and Private aided Government and Private unaided also Private aided and private unaided Science teachers of Secondary Schools.


INTRODUCTION:
Teacher Effectiveness is the salient concern for researchers, policy makers and practitioners. Being one of the significant factors of education it plays a pivotal role in bringing reformation in education system. As a result, whole system of education is concentrating on the movement of Teachers Effectiveness.
We know that Teaching is a very complex process. As it involves the significant factors such as Teachers, Pupils and Subject matter in a dynamic interaction, teachers acts as 'trailblazers' in the lives of learners in the process of education.

Significance of the study:
Modern world is very much influenced by the expectations of the communities. As a result, inventions takes place in various fields to meet the requirements of the society and when the demands arise respective changes are introduced by the inventions of various kinds. Accordingly changes should be introduced in the education system to meet the growing demands of the society through molding its future citizen.
We know that Teacher Effectiveness is one of the significant parameters of education. So, it is the chief concern of educationists to bring about improvement in this parameter to enhance the quality of teachers and their performance. This in turn helps teacher's community to enhance the quality of output. Thus investigator selected this parameter to study.

Reviews: -
The following reviews throw light on the earlier efforts and their relationship on the present study. Rabinowitz and Travers (1953), Rayn (1949Rayn ( , 1953bRayn ( , 1957 as well as Rammers (1952), argued that Teacher Effectiveness could be understood as the effects on students as student gains, student growth and changes in student. Dhillon and Navdeep (2010) explored that there is no significant difference in the value patterns of Male and Female teachers and Government and Private School Teachers. Sawhney and kour (2010) while examining Teacher Effectiveness in relation to self-concept of elementary School Teachers found that there is significant relationship between Teacher Effectiveness and Self-concept of Male and Female elementary School Teachers.

Operational definition:
In this study, Teacher Effectiveness refers to "competencies of teachers in relation to parameters and planning for teaching. Classroom management, discipline, motivation, interaction and evaluation, knowledge of subject, its delivery and presentation including black-board summary, personality characteristics of teachers, interpersonal relations of teachers with others". Tools used for the study: -To study the level of Teacher Effectiveness the investigator has used "kulsum Teacher Effectiveness Scale (KTS)", which is developed by Umme Kulsm.

Objectives of the study:-
Section-I 1.1 Analysis of data relating to the level of Teacher Effectiveness of Secondary School Science Teachers.

2.3: Level of Teacher Effectiveness between Junior and Senior Secondary Schools Science
Teachers.

SECTION III 3. Analysis of data related to Teacher Effectiveness of secondary Schools Science Teachers. 3.1 Hypothesis -1
There is no significant difference between the mean scores of Male and Female Science Teachers of Secondary Schools with respect to Teacher Effectiveness.
To test the hypothesis 1, mean, standard deviation and t-value were calculated.

Hypothesis 2
There is no significant difference between the mean scores of Government, Private-aided and Private-unaided Secondary Schools Science Teachers with respect to Teacher Effectiveness.
To test this hypothesis, one way ANOVA test was applied and the result are presented in table 3.3  Table 3.3 it is evident that, the calculated value of F is 4.078 which is greater than table value at 0.05 levels. Hence, the null hypothesis is rejected and the alternative hypothesis is accepted. This means that there is significant difference between the mean scores of Government, Private-aided and Private-unaided Secondary Schools Science Teachers with respect to Teacher Effectiveness.
F is significant, to know the pair wise comparison of Type of School with respect to Teacher Effectiveness of Secondary School Science Teachers, Tukeys HSD post hoc procedures were followed. It was found that there was no significant mean difference between Private-unaided and Private-aided Schools, Science Teachers. It was found that mean difference in the Teacher Effectiveness between Government and Private-unaided Secondary Schools Science Teachers is significant at 0.05level.

Hypothesis 3
There is no significant difference between the mean scores of Junior and Senior Science Teachers of Secondary Schools with respect to Teacher Effectiveness.
To test the hypothesis 3, mean, standard deviation and t-value were calculated.  Table 3.4 it is evident that the obtained t-value (2.158) is greater than the table value at 0.05level. Hence the null hypothesis is rejected and the alternative hypothesis is accepted. This means that there is significant difference between the mean scores of Junior and Senior Science Teachers of Secondary Schools with respect to the Teacher Effectiveness.

Hypothesis 4
There is no significant difference between the mean scores of Physical and Biological Science Teachers of Secondary Schools with respect to Teacher Effectiveness.
To test the hypothesis 4, mean, standard deviation and t-value were calculated. The studies of Indira (1997) Dillan and Navdeep (2010) support the result that there is no significant difference between Govt. and Private aided Teachers in their level of Teacher Effectiveness.
Discussion: -To sum up, Teacher Effectiveness of Secondary School Science Teachers is not influenced by Gender, Experience and Subject Stream in the present study. Where as in case of Type of Schools there is mixture of result when pair wise compression was made significant difference was found between Govt. and Private-unaided Science Teachers of Secondary Schools. Significant difference was found between Government and Private aided as well as Private aided and Private un-aided Science Teachers of Secondary Schools. Further, it is observed that the relationship between Gender and Teacher Effectiveness is still a matter of controversy because of inconsistent result. The result obtained regarding experience is also contradicting with the earlier research work. So, researcher felt the need of further research regarding aspects, discussed.
