Study of Mathematics Achievement, Mathematical Problems – Solving and Determination to Work by Using Student Team Achievement Division with Problem – Based Learning for Grade 9 Students

Abstract

This research aims to his research aimed to: 1. Compare mathematics learning achievement before and after implementing the combined STAD and problem-based cooperative learning approach for Grade 9 students. 2. Compare post-implementation mathematics achievement with the 65 percent criterion among Grade 9 students.3. Examine mathematical problem-solving ability following the combined approach for  Grade 9 students. 4. Study the work perseverance after implementing cooperative learning using STAD combined with problem-based learning for Grade 9 students, selected by cluster random sampling. The research instruments included lesson plans combined Student Team Achievement Division with Problem-Based Learning, the mathematical achievement test, the mathematical problem-solving test, and the questionnaire about determination to work. Data analysis by frequency, percentage, mean, standard deviation, t-test dependent, and t-test one sample.

              The research results found that:

1. Grade 9 students had mathematical achievement after higher than before learning management was significantly at the .05 level.


2. Grade 9 students had mathematical achievement after learning management was higher than the 65% criterion was significantly at the .05 level.


3. Grade 9 students had mathematical problem-solving after learning management was level of fair for 40.74%, level of amend for 22.22%, level of best and good for 18.52%, respectively.

         4. Grade 9 students had determination to work after learning management over all at high level.
