Mathematics Instructional Package Based on Creative Problem Solving to Improve Adaptive Reasoning Ability and Creative Thinking Ability

This study aims to produce a valid and effective mathematics instructional package use creative problem solving (CPS) models for improving adaptive reasoning ability and the creative thinking ability in mathematics. The instructional package development model used was to modify the Borg and Gall model, and refer to the Dick and Carrey instructional design model. The sample in this research was Chemical Engineering students at State Polytechnic of Sriwijaya. Data collection instruments used were expert validation sheets and tests of adaptive reasoning ability and tests of creative thinking ability in mathematics. The data collected is in the form of data about the quality of the product being developed, namely validity and effectiveness, as well as potential effects of the use of learning packages that have been produced. The instructional package framework developed consists of an introduction, problem exploration, concept strengthening, information extraction, problem solving, concept development, summary, and evaluation, emphasizing freedom of opinion and material developed based on CPS learning. The results showed that the instructional package developed had met the criteria of expected validity and effectiveness. The results of the study using the instructional package showed an increase in creative thinking abilities and adaptive reasoning abilities.
