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 was motivated by the many difficulties experienced by students in the mathematics learning process which had an impact on the occurrence of errors in working on mathematics story problems. These errors need to be known so that it is easier to find solutions so that these errors can be minimized. This research aims to determine the types and causes of errors made by students in solving mathematics story problems on single interest and compound interest materials using Polya's steps. This research method is qualitative with descriptive research type. The research subjects consisted of 2 students from 13 class XI TKP SMKN 1 Pariaman students, with the criteria being 1 student each from the medium group and 1 student from the low group. Data collection techniques include tests and interviews. The results of the research show that the percentage of errors made by students in solving mathematics story problems on single interest and compound interest material using Polya steps is: in question number 1, the biggest error made in the step of understanding the problem was 23.08%. Question number 2, the biggest error made during the rechecking step was 15.38%. In question number 3, the biggest mistake made in the step of understanding the problem was 19.23%. The factors that cause students to make mistakes include, not being used to writing information on questions using their own words, not writing down what they know and what is asked in the question correctly, not focusing when working on questions, not being careful in carrying out the calculation process, not being used to checking again, and rushing through the settlement process.
