Abstract

This research development aimed to develop of worksheet based on guided discovery for increasing mathematical creative thinking and student’s self-efficacy. Development stage in this study is a preliminary study, planning, development of worksheet, worksheet validation, and field testing. The subject of this research is the students of class 10A3 and 10A5 MAN 1 Central Lampung in the Academic of 2017/2018. The data of this research were obtained by observation, interview, mathematicalcreative thinking ability test and self-efficacy scale. The result of the validity by subject matter expert and media expert showed that the worksheet is considered excellent. The Initial field testing results indicate that worksheet is included in either category. The field testing results showed that (1) the student’s mathematical creative thinking aspect was effective because seen from the N-Gain of 0,54 which included in the category of moderate improvement and (2) the student’s self-efficacy was effective because seen from the N-Gain of 0,36 which included in the category of moderate improvement. It can be concluded that worksheet based on guided discovery effective way to improve the mathematical creative thinking ability and student’s self-efficacy.

Abstract

This study is a development research that aims (a) to produce valid and practical Guided Discovery learning to improve the ability of reflective thinking, and (b) to determine the effectiveness of Guided Discovery learning to improve the ability to think reflective.  This research is a Research and Development (R & D). The research subjects were seventh grade students of SMP Paramarta 1 Seputih Banyak in the academic yearof 2018 / 2019. The instruments used are observation sheets, interview sheets, validity assessment instruments, trial sheets, and reflective thinking test instruments. The results of this study are (a) Guided Discovery learning has valid and practical criteria and (b) Average N-Gain scores mathematically reflective thinking of students after given Guided Discovery learning bigger than the average N-Gain score of mathematical reflective thinking skills of students who following conventional learning. Suggestions for developing Guided Discovery learning as an alternative to improve the ability of mathematical reflective thinking in junior high school students.
