Abstract

This study aims to develop Student Worksheet (LKPD) based on the Think Pair Square type of cooperative model on rectangles and triangles material for students of class VII JHS which are valid and practical. This development research uses the Plomp model which consists of three stages, namely the Preliminary Research Phase, the Development or Prototyping Phase, and the Assessment Phase. Based on the results of data analysis, it shows that student worksheets based on the Think Pair Square type of cooperative model on the material of rectangles and triangles in terms of content feasibility, the Think Pair Square cooperative model, language, presentation and graphics have a validity level of 83.33% with a very valid category. LKPD also met the practical criteria from the results of the questionnaire responses of three students who had carried out the One-to-One Evaluation with a percentage of 91.48%. Based on these results, it can be concluded that the student worksheets based on the Think Pair Square type of cooperative model on the material of rectangles and triangles for grade VII junior high school students can be declared valid and practical.

Abstract

This research has a puspose to develop PBL-based learning tools on topic of mathematics induction in class XI MIPA SMA/MA. This design research uses the Plomp development model which comprise of three stages, first the preliminary research, second the development/prototyping phase and last the assessment phase. In the preliminary research, needs analysis, curriculum analysis, concept analysis and student analysis are carried out in order to obtain the main characteristics of the form of the learning tools being developed. In the development/prototyping phase, a prototype design of learning tools was made in the form of PBL-based lesson plans and PBL-based LKPD for mathematics induction material. The prototype must go through formative evaluation in the form of self-evaluation and expert evaluation to obtain a valid prototype. The last stage is the assessment, this assessment aims to determine the practicality criteria of the LKPD prototype which is carried out after the implementation of an one to one evaluation. This research was carried out when Covid-19 was endemic, so there were several stages of research that could not be carried out properly. The conclusion of this study is to obtain PBL-based learning tools on the topic of mathematics induction in the form of lesson plans and student worksheet which are categorized as valid and practical,        Keywords — design research, learning tools, PBL, mathematics induction

Abstract

This-research aims to develop-student’s  worksheets (LKPD) based on problems for 1st grade students of SMA in 1st semester on Nilai Mutlak and Sistem Persamaan Linear Tiga Variabel material. The research model used is Plomp model-that consists of several types, Preliminary,Prototyping and Assessment Phase. On Preliminary, students analysis, curriculum analysis, and concept analysis have been done. Prototyping is the steps to design LKPD that consists of prototype 1 and prototype 2. On prototype 1 self evaluation and expert review have been done-to see the validity of LKPD that have been developed. On prototype 2 there is one-to-one evaluation, by testing the learning tools which have-been validated toward three students. The last-step is assessment-phase that aimed to see the validity and practicality of LKPD. The result-of this research showed-that LKPD based on problems that developed has been valid and practice. Based on the validator evaluation we can get the result is 86,17% that categorized as very valid and the result of three students that has done one-to-one evaluation is 91% which categorized as vary practical.   Keywords __ Worksheet, Project Based Learning

Abstract

Learning mathematics has objectives that must be achieved, one of which is the ability to solve mathematical problems. The low ability of students' mathematical problems is because the learning process is not optimal. Therefore, to overcome this, it takes a learning model that can improve students' mathematical problem management skills, one of which is the Group Investigation type cooperative learning model. The purpose of this is to describe whether the cooperative learning type of Group Investigation can improve the mathematical problem skills of students according to a literature study. The type of research used is a literature study on improving the ability of mathematical problems through cooperative learning model type Group Investigation. The conclusion of this study is to apply the cooperative learning model of the Group Investigation type which has a tendency to be able to improve the mathematical problem abilities of students described in articles relating to indicators in these abilities related to the stages in the cooperative learning model type Group Investigation. Keywords—mathematical problem solving abilities, Cooperative Learning, Group Investigation

Abstract

Mathematics is implemented in various fields of science. However, there is still many students who make many mistakes in solving math problems. Therefore, an analysis of these errors is necessary to apply. This research aims to describe the types and factors which cause students to make errors according to Watson's criteria, namely incorrect data (ID), inappropriate procedures (IP), omitted data (OD), omitted conclusion (OC), response level conflicts (RLC), undirected manipulation (IM), skill hierarchy problems (SHP), and above other (AO). This research itself implements descriptive. Next, 34 students in twelfth-grade social science of SMA Negeri 4 Bukittinggi in the academic year 2020/2021 had participated in the research, and five of them were chosen to be interviewed. The research data were obtained from the test, interviews, and documentation. The data analysis technique was carried out using data reduction, data presentation, and data verification. The results showed that the most dominant type of error is AO which is 33.82%. Furthermore, RLC error is 25.55%, SHP error is 7.90%, IP error is 5.51%, ID error is 5.33%, the OD error is 4.96%, IM error is 4.04%, and OC error is 1.84%. These errors were caused by a lack of understanding about the material, inaccuracy, lack of experience and preparation before carrying out the test. Keywords—Watson Error Analysis, Mathematical Problems
