Abstract

Students faced the difficulty in understanding concept and interpreting of direction of a transformed geometry object, especially translation context. To solved this students difficulty need mathematics learning media which able to clarify translation context and provide them opportunities to learn actively. The aim of this research to know the characteristics and description of mathematics learning media of based computer which is should be valid, practical and effective on translation context in improving the students learning outcomes and their activities. This research wasusingresearch development which apply Plomp model. This model consist of three phase namely initial preliminary research, development or prototyping stage and assessment phase. This research found that mathematics learning media of based computer was valid, practical and effective.

Abstract

This study originated from the critical thinking ability of mathematical learners who are still low. The low critical mathematical thinking ability is due to the unavailability of student worksheets that can support the improvement of critical thinking skills of mathematical learners. The learning process has not been able to help learners to build and develop their knowledge in finding their own principles / procedures of mathematics. The purpose of this study is to produce an inquiry-based learner workbook to improve the critical thinking skills mathematically learners class VIII SMP / MTs. The development research carried out uses the Plomp development model. This Plomp development model consists of three phases, namely the initial investigation phase, prototype development phase and assessment phase. Learning worksheets developed based on inquiry. Based on the development that has been done, obtained the sheet of students of mathematics-based inquiry for class VIII SMP / MTs that meet the preliminary research criteria.

Abstract

This research was derived from the low ability of students’ problem solving. One of the factors was the students didn’t understand the problem of mathematics related to real life and the development of learning media like students’ worksheet had not been optimal yet in school. One of the efforts done was by using students’ worksheet based on Contextual Teaching and Learning (CTL). The purpose of this research is to describe the characteristics of mathematical worksheet based on CTL to improve the problem solving ability of students in junior high school that fulfills the criteria of valid. This research used plomp development model. The plomp model consists of three phases, namely preliminary research, prototyping and assessment phase. Based on the development done, it could be obtained students’ worksheet based on CTL in junior high school valid.

Abstract

Problem solving ability is a very important to attainment of objectives mathematics learning. In fact, the problem solving ability of student is still low. One of the efforts to improve the problem solving ability is handout development on contextual based-approach. The purpose of this development research is to know the characteristics handout on contextual based-approach which are valid, practical, and effective. This development research uses a Plomp model consisting of three phases namely : preliminary, prototyping, and assessment. The instruments were used in this study are validation sheets for RPP and handout, questionnaire for teacher and students, sheets of observation, and test. Handout on contextual based-approach has been valid with validity was 3.58 and it was practical with practicality level of the according to the teachers’ response gave 87,86% and students' response was 82.73%. They also efective to improve the problem solving ability of student.

Abstract

Students’ worksheet is one of learning media to help students in studying mathematics. The worksheet is based on guided discovery learning. It is aimed to get the students accostumed in inventing mathematics concept, therefore the worksheet can make it easier for the students to understand sequences and series material. Sequences and series is one of the essential materials tought in vocational school since it is often correlated to problem solving. In general, the students in vocational school lack of ability to do problem solving. This research used Plomp educational design research that consist of initial preliminary research, development or prototyping stage and assesment phase. The instrument used in this research was validation sheet of students’ worksheet. The aim of this research was to produce valid, practice and effective worksheet. The result of this research showed that the Guided Discovery Model worksheet on Sequences and Series was valid, practical and effective.
