Effects of Problem-Based Learning Activity Management with DAPIC Problem-Solving Processes Affecting Problem-Solving and Mathematical Connection Skills of the Sixth-Grade Students

Abstract

The objectives of the research were to compare 1) the mathematical problem-solving skills of the sixth-grade students learning by using problem-based learning activity management with DAPIC problem-solving processes with the criterion of 70% and 2) the mathematical connection skills of the sixth-grade students learning by using problem-based learning activity management with DAPIC problem-solving processes with the criterion of 70%. The samples used in the research were 24 students studying in the sixth grade in the room 6/1. They were randomized by cluster random sampling. The research instruments were 1) lesson plans by using problem-based learning activity management with DAPIC problem-solving processes and 2) a test for measuring problem-solving and mathematical connection skills on the triangles and multi angles. The statistics used in the research were mean, standard deviation, and t-test.

              The research findings were as follows.

1. The mathematical problem-solving skills of the sixth-grade students learning by using the problem-based learning activity management with DAPIC problem-solving processes were higher than the criterion of 70% with the statistical significance at the level of .05.
2. The mathematical connection skills of the sixth-grade students learning by using the problem-based learning activity management with DAPIC problem-solving processes were higher than the criterion of 70% with the statistical significance at the level of .05.
