Abstract

This research aims to improve the ability to understand the concept of circle equations by applying the Discovery Learning model assisted by Geogebra. This type of research is classroom action research using the Kurt Lewin model which is carried out in 2 cycles and each cycle consists of 4 stages, namely: (1) planning, (2) implementation, (3) observing, and (4) reflection. The data collection techniques used are tests, observation, and documentation with the data analysis used is quantitative data analysis. The research results showed that the percentage of classical completeness in students conceptual understanding abilities reached 66,67% in cycle I and increased to 83,33% in cycle II. The implementation of the Discovery Learning model assisted by GeoGebra also increases teacher activity and student activity in each cycle with a percentage reaching 100%. Based on the research results, it can be concluded that the application of the Discovery Learning model assisted by GeoGebra can improve the ability to understand the concept of circle equations in class XI IPA 3 Student at SMA Negeri 1 Fatuleu

Abstract

This research aims to develop valid, practical, and effective Android-based mathematics learning media using Powerpoint and Ispring Suite 10 on triangles and quadrilaterals for class VII MTs Negeri Kupang. The method used in this research is the Research and Development method using the ADDIE model. The data collection techniques and instruments used were interviews, questionnaires, and tests. The data analysis techniques used are qualitative and quantitative descriptive analysis techniques. The research results show that Android-based learning media on the triangle and quadrilateral material meets the criteria of being valid, practical, and effective. The results of the feasibility of learning media were obtained from the assessment of 3 material and media experts with an average validity of 4.61 and included in the "valid" category. For the practical aspect, the response with average response result was 4.3, the response from small class students was 4.48, and the large class was 4.52 so it was included in the "practical" category. For the effectiveness criteria, the percentage of learning completeness results for small classes was 80% and for large classes, the class completion results were 86.95% so the learning media was categorized as "effective". Thus, the learning media developed is valid, practical, and effective

Abstract

This research was motivated by the mathematics learning results of class IXA UPTD students at SMP N 1 Landu Leko, Rote, especially in transformation material which was still low. The aim of this research is to improve the mathematics learning outcomes of class IXA UPTD SMP N 1 Landu Leko, Rote on transformation material especially reflection and translation. The type of research used is classroom action research (PTK) which refers to the Kemmis & Mc Taggart which consists of 4 stages, namely: 1) planning; 2) implementation; 3) observation; and 4) reflection. The data collection techniques used are observation and tests, while the data analysis is descriptive qualitative and quantitative. The results of this research show that the percentage of implementation of teacher teaching activities in cycle I was 97.5%, increasing to 100% in cycle II, the percentage of implementation of student activities in cycle I was 92.85%, increasing to 100% in cycle II, and the percentage of completion of results Classical student learning in cycle I was 60.86% and increased to 82.60% in cycle II. Thus, it can be concluded that the application of the problem based learning model assisted by animation media can improve the learning outcomes of class IXA UPTD students at SMP N 1 Landu Leko, Rote on transformation material (reflection and translation).

Abstract

This research aims to determine the design hypothetical learning trajectory on statistics material at SD Inpres Waioti.The method used in this research is research design which focuses on developing learning design in form hypothetical learning trajectory. This research is qualitative research using two cycles, namely pilot experiment and teaching experiment. On cycles pilot experiment 4 students were actively involved and teaching experiment involving 12 students. This research was conducted at SD Inpres Waioti. The data collection techniques used were written tests, field notes, and interviews. Meanwhile, data analysis techniques were carried out qualitatively.This research produces something learning trajectory through the PMRI approach which can be used to support the learning process related to statistics, data concentration measures at SD Inpres Waioti class VI. The resulting learning trajectory consists of 7 activities using the PMRI approach as the main or basic reference in every existing activity. The context used in this research is adiwiyata (school that cares and has an environmental culture). Students are asked to observe the school environment with the aim of collecting data directly. Then students are asked to present the data from their observations in tables and bar charts by first sorting the data. The next activity is that students complete the given case and end by determining the mode and median of a data set and finding the formula and determining the mean of a data set

Abstract

The low concept understanding ability of students in class XI MIA 4 SMA Negeri 9 Kupang is the reason for researchers to conduct research. This study was conducted to describe the improvement of the ability to understand the concept of linear program in students of class XI MIA 4 SMA Negeri 9 Kupang by applying the discovery learning model assisted by interactive powerpoint media. The method used is Classroom Action Research (CAR) which refers to the Kemmis & Mc Taggart model with 4 steps, namely planning, action, observation and reflection. Data collection was done by observation and test. This research was conducted in class XI MIA 4 SMA Negeri 9 Kupang with 32 students. The results showed that the average result of concept understanding test at the end of cycle I was 67.5, then increased to 77.2 in cycle II. Classical concept understanding of each indicator also increased from cycle I to cycle II. The teacher activity score reached 100 in cycle I and cycle II. In addition, the student activity score also increased, namely 92.5 in cycle I and reached 100 in cycle II. Thus, it is concluded that the use of discovery learning model assisted by interactive powerpoint can improve students' concept understanding on linear program material

Abstract

Cognitive style is an important factor in the learning process that differentiates between individuals or students in thinking, remembering and behaving cognitively which can influence how individuals absorb and process information. Cognitive styles are classified into two based on psychological differences: Field-independent (FI) and Field-dependent (FD). The aim of this research is to find out how cognitive style on student’s academic performance in mathematics.The approach employed in this research is a descriptive qualitative approach which emphasizes explicit literature review. Based on the studies conducted, this research shows that bothcognitive styles, whether field-independent and field-dependent have a significant influence on the learning process and student academic performance in mathematics subjects. Therefore, the use of appropriate cognitive styles in the learning process can enhance students' mathematics learning outcomes

Abstract

The Corona virus disease 2019 pandemic caused the government issued a policy that changed the habits of schooling in Indonesia which previously adopted face to face system into online learning. This suddenly in the learning process certainly affects the effectiveness of learning and on the process of running this online learning system there are obstacles experienced. The purpose of this study was to describe the effectiveness of online learning and to find out the obstacles in online learning in mathematics subject in VIII Class of SMP Negeri 7 Kupang during the covid 19 pandemic. This study uses a survey method with data collection techniques using a questionnaire in the google form. From the result of this research, online learning of mathematics subject in VIII Class of SMP Negeri 7 Kupang during the covid 19 pandemic was effective and the value of the effectiveness of online learning in mathematics subject was greater than 65. This can be seen from the result of the t test which shows that t count is 16.295 > t table is 1.6909, then Ho accepted and Ha rejected. From the result of the research and discussion it can be seen that the aspects that most support this effectiveness are aspect of motivation and interest. The obstacle that is most often experienced is the internet network which is difficult or sometimes interrupted.
