Development of Teaching Materials Based on Guided Discovery Learning Methods to Increase Mathematical Problem Solving Ability

The aims of this study is to develop teaching
materials based on guided discovery learning that fulfill the
quality criteria of validity, practicality, and effectiveness. This
research was a research and development study using the dick
and carrey development model with consisting of ten steps: (1)
identify instructional goal, (2) conduct instructional analysis, (3)
identify entry behaviors, (4) write performance objectives, (5)
develop intruction strategy, (6) develop and salect instructional
materials, (7) develop criterion referenced test, (8) develop and
conduct formative evaluation, (9) revise instruction, and (10)
develop and conduct summative evaluation. The data analysis
technique used in this study is a descriptive quantitative and
qualitative analysi. The results of this study show that all of the
products are valid, practical, and effective. The product fulfills
the validity criterion by experts appraisal which is in .
The product fulfills the praticality criterion based on
instructional material implemantation and teacher and sttudent
assesment to instructional material, that is in a very good
category. The product fulfills the effectiveness criterion based on
complete of klasikal reaches , the ability of theacher to
manage learning that is in a good category, and the learning time
is not much different from the usual learning time.
