Abstract

Mathematical anxiety has a negative relationship with mathematics performance and achievement. Further explained, mathematics anxiety has an indirect effect on mathematics performance. This research explores sources or factors related to mathematics anxiety among engineering students at a private university in Indonesia. A total of 47 engineering students participated in this survey that randomly chosen based on gender, major, and age. Two main factors are affecting the mathematics anxiety of engineering students, namely internal and external factors. The results show that mathematics anxiety among engineering students is manifested into three aspects. Firstly, the home aspects are talking about the influence of parents and sibling. Secondly, society's issues are discussing self-efficacy, social reinforcement to hate mathematics, and social stereotypes. Lastly, the classroom aspects are talking about the traditional mathematics learning process and classroom culture, namely the experience of learning mathematics in classrooms and relationships between friends during learning. The details of the statements under the aspects also highlight unique problems and are not covered by previous research in mathematical anxiety. Next, differences in mathematics anxiety by gender and faculty were examined.

Abstract

The purpose of this study is to develop a web-based learning game media to improve problem-solving skills in two-dimensional figure. Research method with R & D use the ASSURE development model consisting of 6 steps, that is 1) analyze learners, 2) state objectives, 3) select method, media, and materials, 4) utilize media and materials, 5) require learner participation, 6) evaluated and revise. The validity of the product is assessed by the experts with the expert validation sheets. The practicality of the product was tested by a limited trial of 10 students followed by interviews to see student responses. The Product effectiveness was seen from one class trial with one group pretest-posttest design and the results were analyzed using the Paired-Samples T-Test. The results of this study are in the form of web-based game learning media to improve problem-solving skills in flat-build material. The Learning media is proved valid based on the expert media, material, and learning tests. Learning media was also proved practical based on the results of interviews by 10 students. Learning media is proved effective based on the Paired Samples T-Test which was taken from the results of the pretest and post test

Abstract

This study aims to determine the feasibility of learning media in the form of videos with the help of camtasia software on number material using the R & D (Research and Development) methodology with ADDIE models (Analysis, Design, Development, Implementation, Evaluation). This research was conducted at Cirebon State MTs 2 Cirebon in class VII. The research instrument used was an interview questionnaire for teachers and students, a practicality questionnaire for students and a validation sheet for three lecturers as well as a mathematics teacher. From the results of the instruments in the form of interview questionnaires students are clear that students prefer learning with the presence of learning media and the results of teacher interviews that result in a lack of facilities for the learning process using learning media. The instrument results in the form of a validation questionnaire produce an average score of 85% (very valid), so that it can be said that the learning media in the form of videos are valid and can be used. The instrument of practicality questionnaire filled by nine students with three high-ability students, three moderate-capable students, three low-ability students produced an average score of 86.77%, it can be said that the practice was very high. Based on the results of each instrument, it can be stated that the learning media in the form of CD-shaped videos is practical and can be used.

Abstract

This research was motivated by the difficulties of junior high school students in linear equation system material. The focus of this research is to produce the Hypothetical Learning Trajectory (HLT) system of linear equations based on the development of Learning Trajectory (LT) with the aim of research to improve students' mathematical communication skills. Research method used design Research with 3 phases: Preliminary design, teaching experiment, and retrospective analysis. The subject of study in SMP grade VII in Tasikmalaya district. This research uses the instrument of communication skills test students. Processing of research data using test-T.  Based on the results of the research obtained: (a) HLT results from the development of LT linear alignment system in RME to improve student mathematical communication skills; and (b) students who acquire RME learning have increased mathematical communication skills greater than those who acquire conventional learning.
