Abstract

Quadratic function is one of the important topic in mathematics. The purpose of this study is to describe the mistakes made by students when drawing a quadratic function graph. In this research, the focus of the problem is what type of mistakes made by students in drawing a graph of quadratic functions. The form of error here referred to an error in doing the exercise of drawing quadratic function graph in learning with the PBL model using a true or false strategy assisted by GeoGebra application. The conclusion of this research states that the error in drawing quadratic function graph is dominated by procedural errors. PBL model with true or false strategy with the help of GeoGebra application can be an alternative learning to overcome students' mistakes in drawing quadratic function graphs

Abstract

This research aimed to describe students' mathematical creative thinking ability at SMPNegeri 1 Sumbang. This research belongs to descriptive qualitative research. The subjects ofthis research were the students Grade VII G of SMP Negeri 1 Sumbang. The samples weretaken using purposive sampling technique. The data were collected using questionnaire, test,interview, and documentation. The data validity test used in this research was triangulation.The results of this research illustrate that: 1) Low category students could meet one indicatorof mathematic creative thinking ability i.e. fluency. Their learning motivation was good. Theypreferred to learn in a group. They were enthusiastic when they were given awards during theinstruction. 2) Medium category students could meet two indicators of mathematic creativethinking ability i.e. fluency and flexibility. Their learning motivation was very good. Theywere active during the instruction and they preferred to work autonomously. They sometimesreviewed the lesson that had been learned at school. 3) High category students could mastermathematic creative thinking ability i.e. fluency and flexibility. Their learning motivation wasvery good. When they met hard questions, they would try to solve the problems well. Duringthe instruction, they were active and they preferred to work autonomously.KEY WORDS: Mathematical Creative Thinking, Learning Motivation

Abstract

This study aims to determine the activities of students in learning subjects through True or False strategy of graph theory by media index cards. Observations show a more focused student activity because students already know the material of what will be learned through the index cards that they get in early learning, and they also know the form of matter or issue that they get when studying the learning material on which they will carry. Students focus on the material presented by the lecturers. At the end of the students' learning spirit in concluding that material has been obtained. Lecturers also seem satisfied when getting feedback from students on material that has been given to the student lecturer. Keyword: true or false, cards, graphs, media
