Abstract

Abstract.Snowball throwing is one of the cooperative learning methods. Snowball throwing is packed in the game with simple rules that are easy to apply in learning mathematics.This research is a classroom action research which is purposed to reduce errors in solving quadratic equations with cooperative learning type snowball throwing. The subject of the research is the students of X AP 3 grade SMK Negeri 1 Jember in the academic year 2012/2013. The data which is collected by using observation, interview, and test method. The results of the research showed an increasing in student activity, namely 74.67% in the first cycle and 80.63% in the second cycle. The total percentage of errors decreased, namely 70.18% in the preliminary test, 45.28% in the first cycle test, and 11.83% in second cycle test. Based on the result of the research, it can be concluded that cooperative learning type snowball throwing can increase the learning activity, reduce errors in solving quadratic equations, and decrease percentage of errors.

Abstract

The problem-solving profile is a general description of the activities of solving mathematical problems carried out by students using the five stages of IDEAL model problem solving namely identifying problems, defining problems, finding solutions, implementing strategies, and reviewing and evaluating their effects. This becomes interesting when it is associated with mathematical abilities. This study aims to describe the profile of students with high mathematical ability in solving questions about the subject of Social Arithmetic. This type of research is qualitative research. Students with high mathematical ability were given two problem-solving test questions, then interviews were conducted to find out more in the process of solving them. The results obtained are students with high mathematical ability able to meet all the indicators of each stage of solving the IDEAL model. This can be seen from the results of the work provided and interviews conducted by researchers against these students.
