Abstract

This study aimed to investigate the effectiveness of a cooperative learning type TAI for teaching 3D geometry and to see whether or not the outcome of cooperative learning type TAI was found better for teaching 3D geometry rather than conventional learning model.  This study was a experiment with pretest posttest only control design. The sample are 70 students on the first grade of MA Ismailiyah, Jombang. The sample randomly divided into two classes, that is experimental class and control class. The experimental class used the cooperative learning type TAI, while the control class used the conventional learning model.The instruments consisted of observation sheet for students’ activities, observation sheet for students’ cooperative skills, questionnaire of students’ responses and test sheet of learning outcome. The findings showed that the implimentation of a cooperative learning type TAI for teaching 3D geometry is effective and the outcomes of the students taught 3D geometry using TAI were found better than ones taught using a conventional learning model.

Abstract

This study aimed to describe the process of thinking by prospective teachers of mathematics in making arguments. It was a qualitative research involving the mathematics students of STKIP PGRI Jombang as the subject of the study. Test and task-based semi structural interview were conducted for data collection. The result showed that 163 of 260 mathematics students argued using inductive and deductive warrants. The process of thinking by the prospective teachers of mathematics in making arguments had begun since they constructed their very first idea by figuring out some objects to make a conclusion. However, they also found a rebuttal from that conclusion, though they did not further describe what such rebuttal was. Therefore, they decided to construct the second ideas in order to verify the first ones through some pieces of definition.
