TINGKAT KREATIVITAS SLOW LEARNERS DALAM MEMECAHKAN MASALAH MATEMATIKA

The heterogeneity of students in Indonesia is a challenge for teachers today. Creativity is not only for students with high mathematical abilities, but also introduced to students who are in the slow learner category. This research is a qualitative descriptive study that aims to describe the level of creativity of the slow learner, and to describe how to develop creative thinking skills for slow learners. The subjects in this study from one of the schools in Yogyakarta whose students were included in the slow learner category. The subjects were selected by purposive sampling. Data collection had been done by giving problems solving to subjects, then interviewing them to clarify the answers that have been written. Data analysis had been stopped on the third subject because the data from the third subject was no difference with data from the previous subject. The results of this study indicate that slow learners are not able to show the three indicators of creativity in solving mathematical problems (fluency, flexibility, and novelty), so that the slow learners are classified as creative thinking skills level 0 or included in not creative students. Other findings indicate that one subject indicated being able to show one indicator of creativity, namely fluency, so that subject classified as level 1 (almost not creative).

PENGEMBANGAN MEDIA PEMBELAJARAN BERBASIS PREZI PADA MATAKULIAH ANALISIS VEKTOR

Undergraduate students have difficulties in understanding abstract concept of Vector Analysis and need visualization to support learning. Prezi-based instructional media developed by consider visual principle that support Vector Analysis learning. This study aims to describe Prezi-based instructional media development and produce Prezi-based instructional media that is suitable for learning. Development refers to ASSURE development model (Analyze learners, State objectives, Select methods, media and materials, Utilize media and materials, Require learners’ participation, and Evaluate and revise). The research instrument consisted of expert assessment sheets, test questions and student response questionnaires. Instructional media is feasible to be used satisfy aspects of validity and effectiveness. Assessment of the validity aspect based on the experts’ judgment that is on a valid criterion. While the assessment of effectiveness aspects based on test results are on quite good criteria and questionnaire responses of undergraduate students are on excellent criteria. Learning media consists of menu sections and content sections. The menu section consists of an overview of the material that will be presented in the media. The content section consists of material that can be zoomed in and zoomed out according to needs and learning videos to visualize the concept of Vector Analysis.

KORELASI MODEL GROUP INVESTIGATION DENGAN KEMAMPUAN BERPIKIR KREATIF DAN KEMAMPUAN PEMECAHAN MASALAH

The purpose of this research is to know the relationship of Group Investigation model with creative thinking ability and problem solving ability. Model Group Investigation is a group-based learning model where students are given opportunities to discuss, think critically, and be responsible for the learning. The research method used is experimental method, with sampling technique used is Purposive Sample. The instrument used in this research is the observation sheet of student activity, the question of creative thinking ability and the problem solving test problem. The test used is Pearson Product Moment correlation test, ANOVA Factorial test, and uji t. The results of this study are: (1) student activity in learning mathematics by using Group Investigation model overall percentage reaches 65,6% and included in good category; (2) there is correlation of Group Investigation model with creative thinking ability; (3) there is correlation of Group Investigation model with problem solving ability; (4) there is a correlation of Group Investigation model with creative thinking ability and problem-solving ability; (5) there is difference of average ability of creative thinking and problem solving ability between experiment class student and control class student, with mean value of experiment class is 76,60 whereas mean value of control class is 68,57.
