Abstract

This research intends to study the conditions and problems of learning management in Mathematics for undergraduate students. Research problem is that students have low achievement and ability problem-solving in mathematics. The research method used is development through the stages of conducting preliminary studies and quantitative survey research, producing initial designs of integrative learning models. The results of this research were used to develop the mathematics learning model. The research was conducted over a one-year period considering two groups. The first sample was collected from the group with 376 students studying mathematics in the academic year 2020. The second sample was collected from the group with 116 professors of public universities in Thailand. Questionnaires were used as a tool of the research. The data analysis was divided into 2 stages. The first stage was to analyze supporting factors with factor analysis. The second stage was to design the learning management of students and professors with regression analysis. The results have shown that the opinions of students and professors on conditions and problems of learning management can be summarized as follows: (1) The students’ opinions for corrections in the aspects were group learning and teamwork, steps of solving problems, a learning model that is real situations, and the problem-based learning, respectively. (2) The professors’ opinions for corrections in the aspects were student interaction, academic achievement, problem-based learning, and learning management model that is current situations, respectively. (3)The supporting factors for the development of the learning management model that professors and students were consistent in solving problems. It was found that there were three main factors as follows; group learning, problem-based learning, and active learning. The learning management model should be developed by integrating group learning, problem-based learning, and step of mathematical problem-solving to enhance problem-solving ability and mathematics learning achievement.

Abstract

Mathematical trauma is a mental condition of students caused by experiences that make it difficult or emotionally with mathematics. This study analyzes students’ trauma of mathematics based on grade and gender by using survey research methods and data processing using Winsteps. The subjects of the research were 204 students in every grade in Junior High School. The questionnaire consisted of 20 statements. This instrument was developed measuring mathematical trauma. It consisted of three indicators: difficult to adapt to the environment, saturated with the learning system that is done, and difficult to get along and organize themselves. Based on the Rasch analysis, for the item, two items (I10 and I7) are a misfit, and the rest items are fit. The items were suitable for 147 respondents (72.06%). Based on The Wright Maps table on WinSteps, the percentage of male students who are very traumatized by mathematics is more than female students. Meanwhile, based on grade, students from grade 8 are more very traumatized by mathematics than students from grade 7 and grade 9. Furthermore, based on a questionnaire, students prefer to class condition that made very traumatized by mathematics.

Abstract

Effective teachers are those who are highly engaged and who have an essential role in promoting student motivation and achievement. Thus, this study was conducted to ascertain the engagement of Mathematics teachers and its relation to the learning motivation of students in a state college in the Philippines. It employed the mixed methods, specifically Creswell’s (2014) sequential explanatory approach, with the survey-questionnaire, interview, and focus group discussion as data collection techniques. The findings of the study revealed that teacher’s engagement in Mathematics in terms of “Body Language and Behaviors,” “Consistent Focus,” and “Individual Attention,” were “Very High” while “Rigorous Thinking,” “Meaningfulness of Work,” “Verbal Participation,” “Clarity of Teaching,” “Performance Orientation,” “Interest and Enthusiasm,” and “Confidence,” were only “High.” Meanwhile, students’ motivation to learn Mathematics as to “Relevance,” “Interest,” “Satisfaction,” and “Confidence” were also “High”. The test of hypothesis on significant correlation showed that there was a close association between teacher’s engagement in Mathematics and students’ motivation to learn Mathematics. There was also a corroboration between the quantitative data obtained from the survey and the qualitative data acquired during the interview and focus group discussion. The result further implied that teacher’s high engagement contributes positively to students’ willingness to learn essential concepts and skills in Mathematics.

Abstract

The study aimed to produce PISA-like mathematics problems with the Islamic ethnomathematics approach that were valid and practical. A development study with formative evaluation was used as the method in this study with 32 9th-grade students as the subjects at one of the junior high schools in Palembang, South Sumatra province, Indonesia. There are five phases: self-evaluation, expert review, one-to-one, small group, and field test. Interviews, questionnaires, and tests were used in this study as the instruments to collect the data. The results showed that three experts from the expert review phase assess that 77.78% agree that six PISA-like mathematics problems meet the validity criteria. For the practicality criteria, three students from the one-to-one step set about 77,78% agree, three students from the small group phase assessed about 61,11% strongly agree, and 26 students from the field test phase considered 61,33% agree. This result is supported by the average test result that was classified as a low category. This showed that the results obtained are not optimal because students still did not understand the problems and had difficulty solving them.

Abstract

The article presents a marginal region mathematics teachers' perception of ICT as learning media and the type of ICT media used in mathematics classrooms. A survey was designed including two domains:  the usability and the importance of ICT. A questionnaire was administered to 84 mathematics teachers in marginal regions. The respondents were chosen conveniently based on their accessibility and availability. About 50% of marginal region mathematics teachers do not use ICT in teaching. The most common media used is Microsoft Office software to present teaching materials from internet or digital sources. Using the Rasch model, the data show that mathematics teachers' perception of the usage and importance of ICT as a media of mathematics learning can be categorized as 'medium' level. Mathematics teachers in the marginal regions consider ICT as mathematics learning media to be fairly important.
