Abstract

To improve students' critical thinking skills in solving High Order Thinking Skill (HOTS) questions, the ability to think metaphorically in learning is required. Thus, this study aimed to describe the metaphorical thinking process of students in solving HOTS mathematical problems by PISA approach. In this study, the research method was descriptive with a qualitative approach. The sampling technique was purposive sampling technique, which was a sampling technique suitable for this study. The results showed that based on the works of the three subjects, they had distinct characteristics in solving the problems. S1 who was classified in high category had a metaphorical form by looking at the room from the top side and based on the indicators, S1 had met the metaphorical thinking indicators. S2 who was classified in low category still did not have metaphorical form as compared to the indicators of identifying problems. However, S2 also had gone through metaphorical thinking process when compared to the indicators of connecting and deciding the main concept, as well as was able to illustrate ideas. Meanwhile, S3 who was classified in the middle category had a metaphorical form by only looking at the room side. S3 also had met several indicators of metaphorical thinking.

Abstract

This study aimed to describe the errors that student made in completing the Two Variable Linear Equation System based on Watson's criteria. This was a descriptive qualitative study involving 29 students consisted of of 12 high-skilled students, 5 medium-skilled students, and 12 low-skilled students in 8th grade at SMP PGRI 6 Malang. The data were obtained from the types of errors that student made using the Two Variable Linear Equation System question tests and the results of the interviews based on the Watson's criteria indicators. The question sets used in this study had been verified by mathematics education lecturers and mathematics teachers. The results of this study were: a) high-skilled students were 'less thorough' at work; (2) medium-skilled students were ‘using data incorrectly at the early stages'; while (3) low-skilled students ‘did not give answers' because they did not understand the concepts of the learning materials. The three types of errors frequently made by students were errors in determining the operation to be used (mhk), errors in determining the stages of solving the question problems (mtl), and errors in drawing conclusions from the final results (kh).

Abstract

This literature review aimed to describe the opportunities and challenges of integrating the Learning Management System (LMS) in mathematics learning, especially in terms of the non-technical aspects. Because many LMS platforms which can be integrated into learning process, this review only discusses the three LMS platforms which are common, namely Moodle, Edmodo, and Schoology. This review was conducted with the method as proposed by Templier and Paré (2015), in which the literature materials consisted of journal articles, proceedings, and official websites of LMS. The results of this review showed that integrating the LMS in mathematics learning indicated opportunities in terms of the positive impact which can be obtained from integrating the LMS. On the other hand, the identified challenges were about how mathematics content or materials were organized through integrating the LMS, providing feedback, and maximizing the online discussion facility provided by LMS. Therefore, to obtain the positive impact from integrating the LMS into mathematics learning, teachers should pay attention to these three challenges.

Abstract

This study aimed to describe the conceptual and procedural comprehension to solve linear program story problems in students who are an extrovert and an introvert. This was qualitative study with a case study method. The subjects were two students who are an extrovert and an introvert. Data collection included personality questionnaires, question tests, and interviews. Validity test of the data used time triangulation. Data analysis was conducted based on indicators of conceptual and procedural comprehension, which include data reduction, data presentation, and conclusion drawing. The results showed that the extroverted subject was able to meet all indicators of conceptual and procedural comprehension. This was reflected from the way the subject solved the questions properly according to the existing procedures. In contrast, the introverted student was also able to meet the procedural comprehension indicators, but did not meet the conceptual comprehension indicator. This was reflected from the mistakes that the subject made in comprehending the questions and the errors in interpreting the questions into mathematical model.

Abstract

In the 2013 curriculum, mathematics learning is more directed at higher-order thinking skills (HOTS). HOTS are observed from the abilities of students in solving HOTS type of questions. However, students still make mistakes in solving this type of questions, especially the statistics questions. The students’ errors in solving HOTS type of statistical questions need to be investigated, particularly on the types and causes. This study aimed to describe the errors made by students in solving HOTS type of statistical questions. This study was conducted at SMP Negeri 1 Selopuro, Blitar City Year Academic 2019/2020. This study used descriptive qualitative approach. The subjects were three students of 8th grade B. The instruments in this study were tests, interviews, and documentations. Based on the results of the data analysis, it can be concluded that: (1) reading errors were due to the inability of the students to understand the information in the questions; (2) comprehension errors were due to incomprehension of the students on what to look for in the questions; (3) transformation errors were in the form of inability in generating functions/methods to solve the questions; (4) processing skill errors were in the form of misconnection and misconception; and (5) errors in writing the final answers were due to drawing wrong conclusions.

Abstract

The results of observations on April 15, 2019, at SMP Negeri 1 Peureulak, East Aceh District, and the 2017/2018 National Examinations showed that students experienced difficulties in geometry, so there was a need for teaching materials in the form of LAS (Student Activity Sheets). This development aims to determine that teaching materials in the form of LAS based on Acehnese local wisdom are valid, practical, and effective, and also determine student learning outcomes. This research is a development research using the ADDIE model (Analyze, Design, Development, Implementation, and Evaluation). The subject of the trial in this study was grade VII-1 students of SMP Negeri 1 Peureulak, East Aceh District. Questionnaires, observations, interviews, and tests are used as data collection techniques and instruments in this research. The data analysis in this study is descriptive analysis using the preparation/development of the LAS product variable and the resulting LAS quality variable. As for student learning outcomes in using LAS can be seen from the results of the LAS analysis, which includes student learning outcomes as one of the effectiveness aspect of LAS and test data on learning outcomes. Based on the results of the analysis, it can be concluded that the teaching materials in the form of LAS based on Acehnese local wisdom in mathematics learning especially geometry material in Junior High Schools are categorized as valid, practical, and effective. Student learning outcomes using the LAS have a mastery score with a score of 86.43.

Abstract

This research aimed to describe errors done by students in solving HOTS typed linear equation of two variables problem seen from the cognitive style in a Covid-19 pandemic era. This research uses a qualitative approach. Research subjects consist of 4 students selected among 31 students from class IX Junior High School 1 Petarukan, grouped into two students with cognitive style field-dependent (FD) and two students with cognitive style field-independent (FI). Subjects cognitive style was determined by Group Embedded Figures Test (GEFT) score, while errors in problem-solving were determined through TKPS and interviews. Field-dependent subjects tend to make errors in transformation and encoding with low or fair fallacy rate. On the other side, field-independent subjects tend to make errors in understanding the problems with low fallacy rate. The causes of errors made by field-dependent subjects are not being able to make complete mathematical models and not showing what they had searched. Meanwhile, field-independent subjects were incapable of making sketches perfectly. Other researchers' recommendation explains only errors in reading, transformation, processing capability, and encoding of students with cognitive style FD and FI. In this context, there are still a lot of other errors done by students. Therefore, the next researcher needs to conduct further research with better execution.

Abstract

The learning of addition and subtraction that usually be done in sequence impact students’ tendency to separate type of the strategies employ to solve the related problems. In fact, there are a number of situations that can be observed and solved through both lenses. Therefore, in this study we designed a simultaneous addition and subtraction of two-digit numbers learning trajectory. The learning activities were constructed based on Realistic Mathematics Education (RME) Approach. This design study was conducted in three steps consist of preliminary study, teaching experiments, and retrospective analysis. The teaching experiments were done in two cycle, the first was done with four students and the second was done with 33 students in two classes of an elementary school located in Singaraja, Bali. The data related to number sense ability were gathered from observation and students’ written work in solving worksheet and post-test. The collected data were analyzed using constant comparative method. From the results, we found that a simultaneous learning of two-digit numbers addition and subtraction were effectively develop the students’ number sense and encourage the students to develop efficient counting strategies.
