Abstract

The research aims to: obtaining (1) a description of the types of materials , mathematical ability, and the level of complexity, (2) a description of the absorption of the material, (3) a model of matter UN in terms of NAEP as an alternative evaluation of learning mathematics. This study uses a model of Plomp development consisting of preliminary investigation, design, the realization phase, test, evaluation, and revision, and implementation phases. Type of device being developed is the UN test criteria were reviewed from NAEP and validation sheet. The device is validated experts and colleagues then tested on the subject of new students of class X-2 SMAN 2 Mranggen. The test results were analyzed with biserial correlation, product moment, Hoyt, level of difficulty and discrimination power. The first trial invalid on multiple-choice number 4, 5, 14,15, 16, and 17. Reliability in one package at a high 0.931. The second trial on multiple-choice questions that all valid. At number 7 short answer is invalid, and valid for all extended construction. Reliability on the second package of 0.904 is high. To be able to apply this test the model is necessary to develop and test further.Keywords : NAEP, Procedural Knowledge, Understanding Concepts, Problem Solving, Absorption Student

Abstract

The purpose of this study was to (1) compare the Course Review Horay (CRH) learning model with STAD in improving students' mathematical understanding, (2) describe the increase in mathematical understanding of students using CRH and STAD, (3) find out the feasibility of the Course Review Horay learning model (CRH) with STAD through activities of observing teacher and student activities. The form of this research is quantitative research with semi-experimental research types. The research sample was selected by Cluster Random Sampling obtained by two classes of students X Science 2 and X IPA 3 Takengon N 15 High School. Data collection techniques used are tests and observations. Hypothesis testing uses a 1-party t-test and an increase using the N-gain test. The results obtained by tcount> t table where 2.44> 2.01, with a significant level of 0.05 and dk = 26 + 26 - 2 = 50, thus H0 is rejected and Ha is accepted. The increase in the ability of mathematical understanding using the CRH learning model is more significant at g = 0.66 compared to STAD at g = 0.33. Based on the results of this study it can be concluded that the Course Review Horay (CRH) learning model is better than STAD in improving students' mathematical understanding.

Abstract

To be able to improve students' problem solving abilities, one way is to choose the right mathematics learning model. One of the learning models that can be used is the problem based learning model. The purpose of this study was to re-analyze the effect of the problem-based learning model on students' mathematical problem solving abilities by reviewing, summarizing data and analyzing some of the research results that have been published on Google Scholar as many as 14 articles by means of statistics. The type of research in this article is a type of meta-analysis research. The research steps included data collection, coding, calculating the increase in problem-solving abilities and the effect size, identifying whether there were differences in the average, and drawing conclusions. Based on the results of the study, the average effect size was 2.02 with a very large category. Meanwhile, based on the paired sample t-test, the value of sig (2 tailed) = 0.000 <α = 0.05, which means that there is a difference in the average problem-solving ability before and after being treated with the problem based learning model. Based on the average effect size and paired sample t-test results, it can be concluded that the problem-based learning model has an effect on students' mathematical problem solving abilities.

Abstract

This study aimed to determine the form, the level of effectiveness, and the obstacles and challenge in developing project-based e-learning tool to improve students’ creative thinking skills. The learning media developed are syllabus, lesson plans, modules, and creative thinking skills test. The model which is developed is the Plomp model which consists of some phases namely investigation, design, realization/construction phases and the evaluation, revision, test phase. Based on the validation test, the syllabus was 4.48, the RPS was 4.48, the module was 4.36, and the THB was valid. Based on the practicality test, the students’ responses were 76.25% and the lecturers’ responses were 4.70 and the category is very good. Based on the individual effectiveness test of 43.8% > 5%, classical completeness z count = 0.976 is between the z table and the N-gain test, 2 students had increasing creative thinking ability test scores in the high category, 6 students were in the medium category. Then it can be concluded that the learning tools developed are valid, effective, and practical.
