Abstract

 Student Activity Sheet is one of the learning materials that is often used in mathematics lessons in Indonesia. This study aims to develop student activity with a discovery learning model. The method used in this research is development research which refers to the development stage by Plomp and Nieveen which consists of three stages, namely, initial investigation, prototyping stage, and assessment stage. However, researchers conducted research only up to the step of making prototypes and testing the validation of learning materials. At the initial investigation stage, the data on difficulties in understanding the concepts of students and in the material for the sequence and series determining the nth term were analyzed. At the prototype stage, the researcher developed the student activity sheet which was carried out by adopting the steps of the discovery learning method. The results of developing a valid learning material are useful for providing examples of student activity sheet with a discovery learning model. The results of the validation of the Student Activity Sheet Implementation Plan obtained that the final criteria were very good and were in the very valid category, which means that the student activity sheet is suitable for use in learning.

Abstract

The use of new educational approaches and technologies can be beneficial in integrating 21st century skills and core competencies in education. STEM provides students with an effective learning environment to improve math skills and other 21st century skills. This research aims to explore and synthesize the best stem applications in math learning and its impact on 21st century mathematical competence. There are several studies related to the integration of STEM in mathematics learning to improve 21st century mathematical competence, which includes critical thinking and problem solving, creativity, communication skills, and ability to work collaboratively. The search for relevant data base was conducted in a study published from 2017 to 2021 that examined STEM and 21st century math competencies in formal education. The search strategy was carried out systematically by reviewing articles in the field of Education that had been published in the ERIC, Scopus, PubMed, Science Direct, and Google Scholar databases. Based on the results of systematic reviews of the literature generated that integrating STEM in mathematical learning must pay attention to the content of the lesson, the methods used in learning must be problem-based and project-based, and learning must be cooperative. In addition, STEM integration in math learning tends to improve 21st century mathematical competence especially in critical thinking and problem solving skills

Abstract

This research is motivated by the fact that each student's different way of thinking in dealing with problems will produce different solutions. This different way of thinking is influenced by the schemata of knowledge that are formed in each other's minds. so that diversity can describe the way students think in the learning process, especially in solving problem solving problems. In this case, self-efficacy acts as an affective aspect that affects how students think, motivate themselves, and build confidence in students in the learning process. Therefore, this study aims to conduct a literature review related to the diversity of students' ways of thinking in solving mathematical problems in terms of self-efficacy. The research method chosen in this research is a systematic literature study. Data collection was obtained from the Google Schoolar database using the Publish or Perish application. The results of this study can contribute to further research for researchers who compile research on this issue.

Abstract

This study aims to find out in depth about how much influence gender has on the mathematical creative thinking ability of junior high school students who have previously received the Realistic Mathematical Education (RME) learning approach. The method in this study uses quantitative secondary data analysis methods. The data collection technique used is documentation. Documentation is taken from a thesis that has a relevant topic/title with the same purpose. While the data analysis used in this study is the Covariance Analysis test (Ancova). The Ancova test aims to see how much gender influences the ability to think creatively in mathematics, while before the Ancova test is carried out, prerequisite tests are carried out, namely the Normality test and Homogeneity Test. The results of this study indicate that there is no influence of gender on students' creative thinking abilities. The value of the R Squared Multiple Determination Coefficient obtained is 0.041, which means 4.1% of the achievement of students' creative thinking abilities is influenced by gender factors. The remaining 95.9% is influenced by other factors, one of which is the RME learning approach carried out by previous researchers. So it can be said that the gender factor does not have a major influence on the achievement of students' mathematical creative thinking skills in the mathematics learning carried out.
