1. DELIA A. ARCISO Researcher The Effect of Using Multimedia and Team Teaching on the Science Achievement Level of Fourth Year Students of Libertad National High School

2.  Education encounters over population, education philosophy development and the change of teacher’s role, the spread of illiteracy, lack of staff and the technological development and mass media. RATIONALE OF THE STUDY

3.  Welch, Bownell and Seridan(1999) described team teaching as a restructuring of teaching procedures in which two or more educators who possess distinct sets of skills, work in a co- active and co-ordinate fashion to jointly teach academically and behaviorally heterogeneous groups of students in an educationally integrated classroom setting. RATIONALE OF THE STUDY

4. This study is focused in finding out the effect of using multimedia and team teaching and its uses in education on thestudent’s academic achievement, especially the fourth year students of Libertad National High School in comparison with their colleagues who benefit from this curriculum through traditional education.

17. 1. There is no significant difference between the mean of the experimental group and that of the control group in the pretest of the fourth year students’ academic achievement in the Science subject. CONCLUSIONS

18. 2. There is significant difference between the mean of the experimental group and that of the control group. in the posttest of the fourth year students’ academic achievement in the Science subject. CONCLUSIONS

19. 3. There is a significant difference between the mean of the experimental group and that of the control group in the pre and posttest of the fourth year students’ academic achievement in the Science subject. CONCLUSIONS

20. 3. It is observed that the development of the academic achievement for the experimental group is greater than that of the control group. This stresses the effective use of multimedia and team teaching in presenting lessons. CONCLUSIONS

21. According to the study results which indicated the effective use of multimedia and team teaching compared to the traditional methods of teaching, the study recommends the following: RECOMMENDATIONS

22. 1. Use of multimedia and team teaching in presenting lessons. 2. Stress the use of multimedia as an educational tool in teaching. RECOMMENDATIONS

23. 3. Give training courses to teachers regarding the use of multimedia in teaching not only to Science subjects but also to other subjects. RECOMMENDATIONS

24. 4. Conduct more studies on using multimedia and team teaching in the academic curriculum in Libertad National High School.
