Abstract

This research is motivated by the lack of practical use of student worksheets in schools. This research is development research. The product developed and tested in the form of guided inquiry-based worksheets on Algebra material for eighth grade MTs students. The development model used is ADDIE (Analysis, Design, Development, Implementation, Evaluation). The purpose of this research is to develop guided inquiry-based worksheets that fulfill the aspects of validity, practicality, and effectiveness to help class VIII MTs to better understand the algebraic material. The subject of this study was the eighth-grade students of MTs 1 Landak. The instruments used were validation sheets, observation sheets, and learning outcome tests. The results of instrument validation are categorized as valid with the level of material validation of 76.25% and media validation of 78.7%. The results of LKS implementation observations found a practical level of 78.3%. Learning test results students find an average test of learning outcomes obtained by students of 77.7 with a percentage of classical completeness of students by 80%. The results of this test indicate that LKS is included in the sufficient category.

Abstract

The cognitive process involves three elements in the human memory system; sensory, working, and long term memory. Unless the long term memory does not have enough preliminary knowledge, the working memory will have difficulties in providing meaning and constructing information as a knowledge, so the working memory is overloaded to understand the problems.With regard to that symptom, the aim of this study is to find out the cognitive load in trigonometric learning. The subjects of this study are students of grade X4 SMAN 6 Semarang. The cognitive load in working memory is caused by three sources, including Intrinsic Cognitive Load (ICL), Extraneous Cognitive Load (ECL), and Germane Cognitive Load (GCL). The results show that ICL can not be manipulated, but ICL can be well processed. Then, ECL can be minimized by material presentation techniques through the help of materials that utilize information technology media. While GCL can be improved through problem solving in developing students' mathematical creative thinking skills.

Abstract

This study aims to analyze and prove the existence of resilience influence and creativity to the ability of problem solving in mathematics. The method of study used is survey method with correlational analysis. The population of this study is all students of class X SMK Kharismawita 2, South Jakarta. While the sample is 30 students class X SMK Kharismawita 2, South Jakarta in the academic year 2017/2018. Further, the instruments of data collection consisted of: a questionnaire about resilience and creativity, and a written test of mathematics subjects. The requirements of data analysis consist of: normality, linearity, and multi-collinearity test. The result of three data analysis requirement test obtained by conclusion that the three groups of data come from normal distributed population, the two regression models which are formed are in linear pattern, and there is no relation between the independent variables. Further the hypothesis test is done by correlation and regression test. Eventually, from the results of hypothesis test and analysis, it can be concluded that there is influence of resilience and creativity to the problem solving ability in mathematics. It means that resilience variable and creativity play a role in mathematics learning, which affect the problem solving skills of mathematics. Thus, in the learning, teachers focused on the factors of resilience and creativity of learners and made efforts to improve both of these factors through interesting math learning
