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:
One of the objectives of mathematics learning is to improve the mathematical connection abilities on students. However, our observations showed that the mathematical connection abilities on students at MTs Pancasila, Bengkulu was still poor. This encourages the need for a learning strategy which is able to direct students to connect with what they have learned into everyday lives. Therefore, this study aimed to examine students’ ability in understanding mathematical concepts to solve problems related to cubes and rectangular prism topic. This was qualitative study with the REACT strategy. Cubes and rectangular prism was one of the mathematics topics of the basic competencies which have to be mastered by students in grade VIII. The subjects were 20 students who took the test and seven students who were randomly selected to be interviewed. Data collection included test of understanding the concept in essay form which was previously validated. Based on the results of students’ answers, 20 students have been able to connect between mathematics problems with the learned mathematics topic, the density topic in physics with the volume cube topic, and the question problems with everyday issues. However, it was also found that some students answered the questions with different procedures.

Abstract:
The poor problem solving abilities of students is still a scourge in mathematics learning, mainly in terms of solving mathematical story problems. This is because in the case of story problems, students are required to understand the information and the questions in mathematical problems at the beginning in order to create a mathematical model which reflects the problem being solved. This study aimed to examine the achievement and improvement of students’ abilities in solving mathematical story problems about arithmetic sequences and series using LAPS-Heuristic learning model. The study method was the Intact-Group Comparison. The subjects were 43 students who were divided into two groups. The first group received conventional learning, while the other group received LAPS-Heuristic learning. The results showed that both achievement and improvement of students’ abilities in solving mathematical story problems who received LAPS-Heuristic learning model were better than in students’ abilities who received conventional learning.

Abstract:
The development of technology in the age of the fourth industrial revolution affects almost every aspect of human lives, including education sector. Therefore, learning innovations are needed in order to meet learning objectives. The objectives are coaching people who are competitive and have 4C skills (communication, collaboration, critical thinking and problem solving, creativity and innovation). One of the learning innovations in mathematics is the application of concrete and digital learning media. To explore and summarize the latest facts related to the concrete and digital mathematics learning media during industry 4.0, the authors of this study conducted a research using Systematic Literature Review method. A total of 30 literatures from various databases were interpreted. A review was drawn on the uses, strengths, and weaknesses of digital and concrete mathematics learning media during industry 4.0. The concrete learning media has advantages which include improving students’ problem solving, creative thinking, and visual thinking skills, but it requires more attention and care. Meanwhile, the advantages of digital learning media include increasing the effectiveness and efficiency of learning mathematics, supporting distance learning, and not requiring special maintenance. Nevertheless, there are still students and teachers who are not familiar with technology, some students do not have gadgets, and there are also inadequate internet networks in some areas.

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:
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:
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:
Mathematical communication skill is very important for university students because through communication, students can convey their mathematical ideas, knowledge and arguments. However, the facts show that the written mathematical communication skills of students majoring in Mathematics Education at IAIN Tulungagung are classified as low. The low written mathematical communication skill of students is indicated by errors in writing mathematical symbols on an equation and unsystematic writing of the steps to solve mathematical problems. This study aimed to determine the effectiveness of the Think Pair Share (TPS) learning model using Google Classroom media to improve the written mathematical communication skill of IAIN Tulungagung students. Several previous researchers have reviewed the use of Google Classroom in learning, but it was not integrated with the TPS learning model and did not focus on the influence on students' mathematical communication skill. The study sample was 40 students of the 5th semester in 2019/2020 academic year majoring in Mathematics Education at IAIN Tulungagung who took the Differential Equation course. The data collection was carried out by providing a pretest and posttest before and after implementing the learning using the TPS model with Google Classroom media. Then, the data from the pretest and posttest results were analyzed using the Wilcoxon test because the data were not normally distributed. The results of this study showed that the TPS learning model using Google Classroom media could improve the students' mathematical communication skill.
