Abstract

Nowadays, there are several LPTK in West Kalimantan that have mathematics education courses apart from FKIP UNTAN. This is a challenge for FKIP UNTAN to become the main choice for prospective students. So, it is very important for the FKIP UNTAN mathematics education department to provide quality academic services to students so that they feel satisfied. One of the student satisfaction assessments index in academic services in the Mathematics Education Department of FKIP UNTAN is academic guidance and course implementation. This study will examine how high the level of student satisfaction with academic services in the Mathematics education Department FKIP UNTAN . Furthermore, it will be known what service items should be improved and developed in an effort to increase student satisfaction. The method used is descriptive method with a survey form involving students in 3rd, 5th, and 7th semester. The instrument used is a satisfaction questionnaire. The level of student satisfaction with academic guidance services is 2% of students are not satisfied, 6% of students are not satisfied, 30% of students are satisfied, 32% of students are quite satisfied, and 30% of students are very satisfied. Then for the level of student satisfaction with the lecture process as much as 2% of students were not satisfied, 5% of students were not satisfied, 27% of students were satisfied, 36% of students were quite satisfied, and 30% of students were very satisfied.Keywords: Satisfaction; Academic Services; Academic Guidance; The Lecture Process.

Abstract

Students’ spatial skills in solving problems related to the arrangement of cubes were relatively low. This research was conducted to describe students' spatial skills regarding cube arrangement through problem-based clinical interviews. The design of this study was descriptive exploratory using one class of students as the research sample. Student tests were used to see students' initial abilities regarding cube arrangements. While problem-based clinical interviews were used to dig deeper into spatial skills and student problem solving regarding cube arrangements. The data obtained was processed using descriptive statistics such as average, cumulative frequency and percent score. Furthermore, the data was analyzed and interpreted using qualitative data analysis techniques to explain the phenomena that occur in the field. The results of the study show that the students' spatial skills regarding the cube were still relatively low; students' spatial skills were not in accordance with the concepts related to solving the problem of unit cube arrangements; students' spatial skills did not show skills related to solving problems in unit cube arrangements; to transform students' skills into spatial skills related to the problem of cube arrangement it is necessary to re-emphasize spatial skills which include spatial visual, spatial perception, spatial relations, and spatial orientation.Keywords: Spatial Ability, Problem Based Clinical Interview

Abstract

The purpose of this study was to improve the activities and learning outcomes of students of class XI MIA 3 in SMA Negeri 1 Sekadau in the academic year 2019/2020 on matrix material using peer tutoring methods. This type of research is a classroom action research carried out in 2 cycles, each cycle consisting of 4 stages of planning, action implementation, observation and reflection. Retrieval of data through a collection using a collection of observations and learning outcomes are obtained by providing a final test at the end of each cycle. The results of observations for student activity during pre-cycle 67.81% in the first cycle to 76.88% and in the second cycle to 86.46% means that there is an increase of 17.82%. Mathematical learning outcomes from the first cycle increased by 41.00%, while from the first cycle to the second cycle increased by 14.46%. So it can be removed by using the peer tutoring method to increase the activity and learning outcomes of students of class XI MIA 3 of SMA Negeri 1 Sekadau in the academic year 2019/2020 on matrix material.Keywords: activities, learning outcomes of peer tutoring methods, matrix

Abstract

This research is a case study which aims to examine and describe the learning independence, learning outcomes, and student responses to the implementation of lectures with the edmodo-assisted online learning sistem. The subjects of this study were 142 students of the Mathematics education program FKIP Untan Pontianak in 2020 that who programmed the differential calculus course. This research activity in the process involves three senior students as collaborators (research assistants). Lecture practice is carried out by the lecturer who teaches these courses. This research procedure consists of: (1) reviewing the material, preparing research tools and instruments (developing and standardizing instruments). (2) Conducting lectures using the online learning sistem assisted by Edmodo. (3) Distributing questionnaires to obtain independence data, providing learning outcomes tests, and providing questionnaires to get student responses to the implementation of learning - (data collection). (4) Conduct studies and interpretations of the data obtained. (5) Reporting. The results of this study indicate that the learning independence of students in lectures is still not satisfactory. Student responses to the learning sistem were 57.04% giving positive responses, and 42.96% giving negative responses. For learning outcomes, 74.65% were able to achieve a score ≥ 70 and no one got a score less than 60. In this case 57.75% got a B grade and 16.90% got an A. It is clear that learning with the edmodo-assisted online sistem is able to make a fairly good contribution to differential calculus lectures.Key words: Calculus, Independence learning, Mathematics

Abstract

There are facts obtained through interviews and observations of students' answers that the VII grade students of SMP LKIA Pontianak are suspected of having misconceptions. Based on theses facts, the purpose of this research is to reveal the form of misconception based on Mason stages and the causes of the misconception. The subjects involved in this research were fifteen students. This research is a case study research with a descriptive method. Data collection tools used modified CRI diagnostic tests and interviews. Based on data analysis, the misconceptions experienced by students in completing set operations consisted of notation misconceptions, generalization and specialization. Researchers found out of the three forms of misconception, the most common is notation misconception. In the problem solving stage according to Mason consists of three stages, namely  entry, attack, and review, students who experience misconceptions in two stages, namely at the entry stage, students experience notation misconceptions and at the review stage, students experience misconceptions of notation, generalization, and specialization. Researchers found the causes of misconceptions consisted of three factors, namely students' associative thinking, incomplete / wrong reasoning, and wrong intuition. Researchers found out of the three forms of misconception, the most common is wrong intuition.            Keyword: Causes of Misconceptions, Mason Stages, Misconceptions
