Abstract

This research is motivated by the low students mathematical communication skills. To overcome this problem is by improving the learning process that provides opportunities for students. One of them is by applying the 5E Learning Cycle model. The 5E Learning Cycle model is a series of activities so that students can master the competencies achieved in learning by taking an active role, directed to seek and discover new knowledge themselves. The research is to investigate the impact of the application of Learning Cycle 5E on mathematical communication skills in terms of overall, ability level and, interaction between learning model and ability level. This research is a quasi-experimental study with a pretest post-test control design. The results of data analysis show that the mathematical communication skills of students who learn using the 5E learning cycle model are better than students with conventional learning. For students mathematical communication skills at the moderate level, the 5E learning cycle model is better, but not better for high and low levels. There is no interaction between the learning model and ability level of mathematical communication skills.

Abstract

This research is motivated by the low ability of students to solve mathematical problems (KPMM) and the teacher has not been optimal in developing mathematics learning tools independently. The purpose of this study was to produce mathematics learning tools through the application of the Problem Based Learning (PBL) model to facilitate KPMM students of SMP Negeri 2 Pangkalan Lesung on number pattern material. This type of research is development research using the 4-D model. Learning tools developed in the form of syllabus, lesson plan (RPP) and student worksheets (LKPD) and KPMM questions. The instruments in this study were validation sheets and student questionnaires. Validation sheets consist of syllabus validation sheets, lesson plans validation sheets, and student worksheet validation sheets, while student questionnaires are in the form of student response sheets. Based on the results of the validation analysis, it shows that the device being developed is very valid. The result of the validation of the syllabus was 3.79; the average RPP score was 3.67; and the average LKPD score was 3.66. The student response questionnaire on the small-scale test showed an average percentage of 94.67% with the very practical category. The learning tools developed were valid and practical for use by students of SMPN 2 Pangkalan Lesung.

Abstract

The student learning activities do not support developing mathematical problem solving abilities. One of the factors is the learning tools used have not provided the opportunity for students to hone their mathematical problem solving skills. This study aims to produce a valid and practical semester VIII class SMP mathematics learning device for use by using the Problem Based Learning Model with a scientific approach to the SPLDV material. This type of research is a development research with the ADDIE development model which includes the following steps: (1) analysis, (2) design, (3) development, (4) implementation, (5) evaluation. Data were collected through observation, interviews, and student response questionnaires. The subjects of this study were students of class VIII MTS GUPPI Bandar Sungai. Data analysis techniques used qualitative and quantitative statistics. Based on the results of data analysis, information was obtained that the learning device met the valid and practical criteria. The results of the validity of the learning tools in the form of a syllabus with a percentage of 82.99%, RPP 85.75% and LKPD of 83.23% fulfilled the validity level, namely valid. The results of the practicality of the learning tools seen from the student response questionnaire were 92%, these results met the practicality level, which was very practical, while in terms of the teacher's observation sheet it fulfilled the practicality level of 87.78% fulfilling the very practical level.
