Abstract

The aim is to improve students' mathematical communication skills that are valid, practical and effective. Development research is carried out which produces student worksheets (LKPD) based on problem based learning (PBL). This development research using the Plomp model consists of three stages, namely, Preliminary research, Prototyping and Assessment. The research subjects were students of class VIII SMPN 17 Padang. The problem based learning model is a learning model that starts with problems that exist in the daily lives of students which has five stages, namely students are problem oriented, students are organized to learn, educators help independent and group investigations, students can develop and present the work and present it, and analyze and evaluate the problem solving process. LKPD validation is carried out by mathematics education experts, language experts and educational technology experts. The practicality of the LKPD is seen from the practicality questionnaire of students. The effectiveness of LKPD is seen from the competence of students which consists of aspects of attitudes, knowledge, and skills. Analysis of the validity data shows that the problem-based learning tool produced is valid. The results of practical data analysis show that the resulting learning tools are very practical. Learning tools have also been effective in student learning outcomes.

Abstract

Understanding of mathematical concepts is one of the cognitive abilities that must be possessed by every student in mathematics learning. But from student learning outcomes it can be seen that the understanding of mathematical concepts of students of VIII SMP 30 Padang is still low. An alternative that can be used as a solution to this problem is to implement a model Learning Cycle 5E. This study aims to determine whether there is an influence of the conceptual ability to of class VIII SMP 30 Padang through the model of Learning Cycle 5E. This type of research is quasi-experimental design with Static group design. Sampling was randomly selected and VIII 5 was selected as experimental class and class VIII 3 as control. The results showed that the understanding of mathematical concepts students' that applied the model of Learning Cycle 5E is better than students are learning to apply the conventional learning.Keywords – Learning Cycle 5E, the ability of understanding the concept, learning directly
