THE EFFECTIVENESS OF USING THINK PAIR SHARE (TPS) AND JIGSAW COOPERATIVE MODELS IN MATHEMATICS LEARNING ON PROBLEM SOLVING ABILITY IN CLASS VII SMP

Common student problem-solving ability is related to several factors. The use of cooperative models in learning is one of the possible factors that can improve student problem-solving abilities. This study aims to determine the effectiveness of using the think pair share cooperative model and the cooperative jigsaw model on seventh-grade students' problem-solving ability of the odd semester of SMP Negeri 1 Tembarak in 2018/2019 academic year. The research population consisted of class VII students of SMP Negeri 1 Tembarak in the odd semester of the 2018/2019 academic year, which consisted of classes VII A, VII B, VII C, VII D, VII E, VII D, VII F, totaling 169 students. Samples were taken from class VII A as the first experimental class using the think pair share cooperative model and class VII D as the second experiment class using the jigsaw cooperative jigsaw techniques using essay questions to obtain data on students' problem-solving abilities. The research instrument test includes a validation test, reliability test, difference power test. The analysis prerequisite test includes the normality test, homogeneity test, initial ability test, hypothesis test. The results showed differences in students' problem-solving abilities who used the think pair share cooperative model using the cooperative jigsaw model. This is indicated by  then  rejected  received. From the research results, students' problem-solving ability using the cooperative model, think pair share, is higher than using the cooperative jigsaw model. This is indicated by then  rejected  received

Design concepts for the development of cooperative problem-solving systems

There are many problem-solving tasks that are too complex to fully automate given the current state of technology. Nevertheless, significant improvements in overall system performance could result from the introduction of well-designed computer aids. We have been studying the development of cognitive tools for one such problem-solving task, enroute flight path planning for commercial airlines. Our goal was two-fold. First, we were developing specific systems designs to help with this important practical problem. Second, we are using this context to explore general design concepts to guide in the development of cooperative problem-solving systems. These designs concepts are described
