This study aims to analyze the effectiveness of SAVI approach-based teaching materials developed for mathematical connection ability. This study was research and development. The subjects were 36 Grade 8 students and a mathematics teacher and the objects were the SAVI approach-based teaching materials oriented to the mathematical connection ability. The effectiveness of the teaching materials measured by four aspects: (1) the observation of the teacher's ability to manage the learning should at least be in the "good" category, (2) six of the eight aspects of students activities are within the ideal time interval, (3) the students' mastery learning are fulfilled both individually and classically, and (4) the student and teacher questionnaire responses show positive responses. The results revealed that the effectiveness criteria were fulfilled. The observation of the teacher's ability to manage the learning was in the very good category (4.22). The student activities in learning was within the threshold for achieving the ideal time. Also, The students’ mathematical connection ability satisfied the mastery learning individually and classically (84.11%). The teacher and student questionnaire responses showed positive responses. Thus, the SAVI approach-based teaching materials oriented to mathematical connection ability are feasible as a learning resource for students in learning mathematics.

The gap between the concept image and the concept definition will greatly affect a person’s understanding of the concept. This study aims to reveal the gap between the concept image and the concept definition, and the causes of the emergence of the gap. The research subjects were 16 first-year mathematics students at one of the universities in Aceh, Indonesia. Data were obtained from the results of written tests and in-depth interviews. This qualitative research with a phenomenological study approach was analyzed descriptively. The results showed that the gap that occurs in the concept includes: the division of a non-zero number by zero yields infinity, the concept of dividing zero by zero is zero, the concept of dividing a number by zero is the same as the concept of the limit, e.g., , and the concept of the left-hand limit as means that the satisfied value of x is all negative numbers such that . The emergence of these concept images results from the subject's learning experience at school and a calculus course. This finding provides insights and considerations for educators to comprehensively introduce students to the concept of infinity to avoid misunderstandings in limit and next materials.

General purpose of this research is to get information about mastery of mathematics concept and improvement the ability of senior high school 11 in Banda Aceh student in creative thinking with Problem Posing model. Understanding the concept is the ability of students to repeat and link the concept that has been studied with the material being studied. Creative thinking is the ability to reason organically and evaluate the quality of a reason systematically. Problem Posing learning model is one form of cooperative learning model that emphasizes the participation and activities of students to find their own material (information) lessons to be learned through the materials available. This research was conducted in senior high school 11 in Banda Aceh especially class XII-IPA1 as experiment class and XII-IPA2 as sample class. The research type is experiment with quantitative approach. Instrument test in the form of a description of 4 questions with the highest value of 100 and the lowest 0. The instrument is used to determine the ability mastery of concepts and creative thinking of students. Before being used to test the students 'creative thinking ability in the implementation of the research, the test questions are tested to other schools to know the validity, reliability, power of the pretest and posttest. Technique data processing is analyzed with quantitative statistics tests students' creative thinking ability. For data processing researcher using SPSS 17.0. Normality test results can be seen the value of pretest class expression and control class sig. = 0.300; 0.120> 0.05 means both classes are normally distributed. Based on the calculation, the value of sig (2-tailed) = 0.002 / 2 = 0.001 shows that sig. (1-tailed) <0,05 so it can be concluded that the improvement of concept comprehension and creative thinking of experimental class students is better than improvement of student's creative thinking conventional class.

Abstract: A new civilization in the world of education caused by the COVID-19 pandemic crisis has triggered the reformulation of learning activities. The consensus regarding this reformulation has resulted in a transition to a virtual-based learning process (PBV). Correspondingly, throughout 2020 there have been numerous individual studies on the effects of PBV with inconsistent findings. A meta-analysis study was conducted to analyze related findings, and consider the results for future PBV implementation. Research samples in the form of individual studies were collected from the ERIC, SAGE, and Google Scholar databases. This study considers learning outcomes as a moderating variable. The estimation method uses a random-effect model, and the calculation tool is the Comprehensive Meta-Analysis (CMA) software. The results of the analysis revealed that overall PBV had a moderate impact on student learning outcomes (ES = 0.67; standard error 0.15). The results of the moderator analysis revealed that the implementation of PBV was more effective in low-level cognitive domains. The implications of the research results are discussed to provide important information as a fundamental idea for further PBV research and development.

The purpose of this research is to describe the analysis of knowledge to be taught on limit of function. This research is part of the didactic transposition research on the concept of limit of function which consists of four stages. Qualitative research with descriptive method is used in this study. The target is a differential calculus course taught in the first semester at a university in Aceh. Data collection techniques consist of documentation studies and unstructured interviews. Analysis of calculus text book documents, especially on limit functions, was carried out using a praxeology approach. The results of the analysis show that the description of the differential calculus course contains material on the real number system, functions and graphs, limits of functions, continuity of functions, derivatives of functions, and applications of derivatives. This is different from the presentation of material in RPS which is compiled by a team of lecturers supporting differential calculus courses. For presentation of material in calculus textbooks, the concept of the limit of a function begins with an intuitive or informal introduction to the concept. Several cases are given to deepen the concept of limits through graphs, analytics, and numbers.

The character of Industrial Work Culture is universal, so it can be adopted to be applied to vocational education institutions as a basic thing so that later when students enter industry they will find several similar characteristics that students must already have. This study aims to realize a development design (blueprint) in instrument development. This investigation aims to produce an instrument that can be used to develop and measure the industrial work culture character of vocational students, especially those in Aceh. So far, the development of industrial work culture character has been mandated to be implemented by the Indonesian government. The theoretical basis of this study is the theory of Kartwohl and Bloom (1956). The affective domain is a domain related to attitudes, values, feelings, emotions, and stages of acceptance or rejection of an object in teaching and learning activities. Affective assessments need to be carried out in the same way as cognitive assessments, so students must have character competencies that can be measured like cognitive competencies. The affective domain is divided into five categories, namely: Receiving or Attending, Responding, Valuing, Managing, Characterization. The affective domain requires measurement tools like the cognitive domain so that students' affective competence is also better developed. Character is an affective domain, the design of the Industrial Work Culture Character Instrument (IKBKI) in carrying out this study was limited to five characters, namely: discipline, hard work, honesty, responsibility, and entrepreneurship.
