Abstract

This research was motivated by students lacking enthusiasm and being less active in learning mathematics. One effort to overcome this problem is to develop problem based learning worksheets because they can help teachers in developing student centered learning which makes students active in learning. This type of research is development using the ADDIE development model which has 5 stages, namely analysis, design, development, implementation and evaluation. Product trials were carried out at SMP N 1 Kuantan Hilir. The research subjects were 10 students in class VIII.2. The research results showed that problem based learning worksheets were valid by two validators. Worksheets based on problem based learning were declared practical with a score of 63%. So that problem based learning worksheets are valid and practical. From the research, it is recommended that teachers use LKS based on problem based learning as teaching materials and several shortcomings during the research include: (1) in groups of students only a few people are looking for answers and apart from that they only see answers from their group friends (2) students tended to tell stories during learning (3) the researcher did not take all the subjects in the class (4) when filling in the practicality sheet the students were not honest.

Abstract

This research is motivated by the still low level of attention and participation of students during the process mathematics learning. Media used to support learning only use the Mathematics package book for class VII independent curriculum and learning is still centered on the teacher. Based on these problems, researchers developed mathematics Student Worksheets based on constructivism on quadrilateral material for class VII SMP Pertiwi 2 Padang. The aim of the research is to produce a valid and practical constructivism-based mathematics worksheet on rectangular plane material. This type of research is development research. In this study, researchers used research procedures by Borg and Gall. Data used to assess the validity of the media were obtained from validation sheets by worksheets characteristic and language experts and design experts, while the data used to assess practicality is obtained from the sheet student practicality. The worksheets developed contains flat material rectangular . The product validity assessment was carried out by two lecturers and declared valid for use from the aspects of worksheets characteristics, language and design. Practicality assessment from students' practicality questionnaire at the test stage try with practicality criteria of 77.46% based on ease of use use, ease of understanding, and time required. So it can be concluded that the constructivism-based worksheets in class VII mathematics learning at SMP Pertiwi 2 Padang is valid and practical to use as a mathematics learning medium. Based on the results of this research, researchers suggest that this worksheets can be used as an alternative media by teaching staff.
