Abstract

This study aims to determine the students’ mathematical representation ability and confidence character assisted by Schoology with the Numbered Heads Together (NHT) method and thematic approach and describe the mathematical representation ability based on the character of self-confidence. The subjects of this study were students of class VIIF and VIIH, one of Junior High School in Semarang. The method used is a mixed method. The results of the study show that: (1) The students’ mathematical representations ability and confident character assisted by Schoology with the NHT method and thematic approaches are better than learning without Schoology; (2) the mathematical representation ability based on the character of self-confidence is (a) students with high self-confidence implement indicators visual and symbolic representations; (b) students with medium self-confidence implement indicator symbolic representation; and (c) students with low self-confidence not implementing of indicators visual, symbolic, and verbal representation abilities.

Abstract

This study aimed to describe students' critical thinking skills towards the concepts differences in finding the area of a plane region and definite integral. This study used an exploratory test survey method with test instruments. Data were taken from 40 students of the mathematics department at a university in Central Java. The results showed that students' critical thinking skills towards the concepts differences in finding the area of a plane region and definite integral were in the medium category. The students' critical thinking skills towards the concepts differences in finding area of a plane region and definite integral were medium (47.5%), with clarification by 57.5% (medium), assessment by 40.0% (medium), inference by 65.0% (medium), and strategies by 27.5% (low). These weaknesses are expected to be followed up by conducting learning that can show the linkages between the concepts and with various ways.

Abstract

Provision of geometry material carried out at several levels of education confirms that the burden of children's knowledge in receiving different geometry material is adjusted to the ability of children at each stage. This agrees with the theory of geometry thinking conveyed by Van Hiele. One of the constructivism learning models that is expected to be able to improve problem solving skills in students, including the 7E Learning Cycle model. The purpose of this study is (1) to describe the development of Van Hiele Geometry thinking skills in students in solving open ended problems in 7E Learning Cycle learning, and (2) describe the Van Hiele Geometry thinking skills of students in solving Open Ended problems in terms of Self Efficacy in learning 7E Learning Cycle. The population in this study were students of class IX Junior High Schoolof 2 Kudus. Sampling was done by using purposive sampling technique, 6 subjects were selected, with 2 subjects for low self efficacy, 2 subjects for medium self efficacy and 2 high self efficacy subjects from class IX A as the experimental class.

Abstract

Abstract Mathematical literacy skills need to be improved so that students are able to solve mathematical problems correctly. This study aims to (1) To find out the mathematical literacy abilities of students in the PjBL model with the RME approach assisted by media, Schoology can achieve classical completeness or more; (2) To find out which one is better between the average mathematical literacy abilities in the PjBL model, the RME approach is assisted by Schoology's media in the experimental class and the DL model's Scientific approach in the control class. The population in this study was VII grade students in a school in the city of Semarang. This research is quantitative research. Sampling is done by random sampling technique. The results of the study showed that using the PjBL model of the RME approach assisted by Schoology in achieving classical completeness, and learning the PjBL with the RME approach assisted by the Schoology media in the experimental class had an average mathematical literacy ability compared to DL learning Scientific approaches in the control class.

Abstract

A factor that contributes to students’ low performance in Calculus is that some teachers and lecturers tend to explain the concept of integral by using a set of symbols, notations, and rules without providing any contexts or representations of the concept. This study was aimed at supporting college students’ understanding of integral by integrating Maple in the learning process using Maple-integrated workbook. This study adapted Brog and Galls’ procedures which consist of collecting preliminary information, planning, developing, validation and preliminary revision, field test, and final revision. The subject of this study was college students’ of Mathematics Education Department of UPS Tegal. The result showed that module developed was in a good criteria, and the conceptual understanding test showed that 82,4% students in the experimental class got a score of 71 or higher. Moreover, the average score of the experiment and control class also confirmed that the average of students’ score in experiment class was significantly higher than that of students in control class.
