Manipulative instructional materials in geometry for grade 9

Thesis (Bachelor of Secondary Education major in Mathematics) -- University of Rizal System-Morong.

EXCUTIVE SUMMRY: This study was conducted to determine the level of performance in Mathematics of Grade 9 students using the manipulative instructional materials in University of Rizal System Laboratory School, School Year 2014-2015. Experimental method was employed in the study which utilized pretest-posttest two groups design. The developed Manipulative Instructional Materials were used in teaching the experimental group and the traditional method was used in teaching the control group. To determine how to Manipulative Instructional Materials in Geometry developed, qualitative description was used. To determine the level of performance of the control and experimental group as revealed by the pretest and posttest results in terms of different lessons, mean and standard deviation were applied. To determine the significant difference between the performance of the control and experimental group as revealed by the pretest and posttest, dependent t-test was used. To find out the significant difference between the performance of the respondents in the control and experimental group as revealed by the posttest results in terms of different lessons in Geometry, independents t-test was used. And, to determine the effectiveness of the developed Manipulative Instructional Materials in Geometry, mean percentage increase was used. There is an increase on the level of performance of respondents in the control and experimental group as revealed in the pretest and posttest in terms of the different lessons in Geometry in Grade 9. There is a significant difference on the level of performance of control group and experimental group as revealed in the posttest results in terms of different topics in Geometry grade 9. The developed Manipulative Instructional Materials are valid and can be used effectively in teaching Geometry for grade 9. The researchers recommended that the developed manipulative instructional materials be used in other lessons in Geometry. The activities using the instructional materials be used in other lessons in Geometry. The activities using the instructional materials may be modified for further analysis. The parts of the manipulative instructional materials may be modified and improved. Develop high quality packaging for better presentation of the whole instructional materials is recommended. Furthermore, conduct parallel studies other models in understanding other fields of mathematics.
