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:
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:
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:
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.

Abstract:
The purpose of this study is to analyze mathematical problem-solving abilities based on Polya's steps and the causes of students' errors in solving mathematical problems. The problem-solving stage consists of 4 stages, namely the stage of understanding the problem, planning a solution, carrying out a solution plan, and looking back. This study used 6 subjects from 25 eighth grade students of SMP Terpadu Turen. Data collection is done by tests and interviews. Data validity test is done by triangulation technique. The results of this study were (1) at the stage of understanding many students, they did not experience difficulties because students were able to understand the problem, (2) at the planning stage there were some students who did not write the completion plan but understood the way they would do to solve the problem but they were not used to write down the plan, (3) at the stage of carrying out the plan there were some students who have difficulty because they are less thorough so that they are not aware of the mistakes made. This is because students lack concentration in solving problems, (4) at the stage of looking back there are students who have not reached this stage because they have not completed the previous stage.

Abstract:
The study was conducted to analyze student errors in the statistical problem-solving process using Newman in terms of metacognitive tacit use. The research method used is qualitative method. Data analysis used is the analysis of the results of the test, questionnaire analysis and analysis of interview transcripts. Based on the results of the study, it was concluded that the subjects of tacit use metacognitive categories did not know their weaknesses in the learning process, gave inconsistent answers, had little confidence, focused only on answers and not on the process. Subjects with tacit use metacognitive categories made mistakes in solving statistical problems almost at all stages of Newman. Newman's error analysis consists of reading errors, comprehension errors, transformation errors, process skills errors, encoding errors. The subject is wrong in interpreting the symbol, the subject cannot determine what is known and asked about the question, the subject does not write detailed calculation steps, and the subject cannot conclude the final answer to the problem solving. Errors in completing the test questions occur because the subject does not re-check the answers given in the problem.
