Abstract

Problem-solving is one of the most important abilities possessed by prospective mathematics teacher students. One way to develop student problem-solving abilities is to use learning models designed to develop problem-solving abilities. This study aims to develop a trigonometry module to develop valid, practical, and effective mathematics education student problem-solving abilities. This research is a research development (Research & Development). This study develops a trigonometric course module using the 4D development model (Define, Design, Develop, Disseminate). The instruments used consisted of validation sheets filled out by experts in the field of mathematics education, student practicality assessment sheets, and learning outcomes tests with problem-solving questions. The quality of the developed modules is viewed from the aspects of validity, aspects of practicality, and aspects of effectiveness. The result is that the module is included in the valid category, with a high practicality value. The aspect of effectiveness based on test learning outcomes with problem-solving problems has increased from the results of the pretest and posttest. The result of the development in this study is the product of a trigonometric course learning module that is valid, practical and effective, and suitable for use by mathematics education students. The contribution of this research is that this module can be used during Trigonometry lectures.

Abstract

Many indexes are involved on ordinary power series calculation. One of the most valuable discovery on previous research is Ops Transformation which able to simplify notations of ordinary power series to avoid some more complicated manipulations. The aim of this research is to generalize the concept of Ops Transformation to gain more benefit and wider applications. The main result of this research is a new formula of generalization of Ops Transformation which called C-Type Ops Transformation. Such transformation is able to solve some differential equations which involving Taylor series

Abstract

Some mathematical material will be challenging to understand without learning media, primarily topics that requires visualization, such as geometric transformations. This study aims to describe the process of developing interactive learning media based on the Adobe Animate application of geometry transformation. It also describes the validity and practicality of the developed learning media. This type of research is research and development. The product developed was an interactive learning media application on geometry transformation material created using Adobe Animate. The development model used was the Multimedia Development Life Cycle (MDLC), consisting of six stages: concept, design, collection of materials, manufacture, testing, and distribution. The research found that the interactive learning media developed were fairly valid (80.12%), with a high level of practicality (4.19). Overall, the learning media developed is feasible to be used in the learning process or as a means of independent learning for students of geometry transformation.

Abstract

Changes in government policy that abolished the national exam into a national assessment have an impact on teacher competencies that must be developed in preparing matters related to the national assessment. The Minimum Competency Assessment (AKM) field focuses on literacy and numeracy activities. Literacy is not only related to text but can be in the form of symbols, numbers, charts or graphs. Based on the results of research on AKM, it was stated that 12 out of 44 teachers as respondents had not yet prepared for AKM. Therefore, training to improve teacher competence in making AKM questions that focus on student numeracy needs to be carried out. This service was held at SMPN 1 Martapura and was attended by 30 teachers who were members of the Mathematics MGMP for SMPN Banjar Regency. The material presented in this activity was about the meaning and purpose of AKM, AKM components, forms of AKM questions, numeracy competency levels and links to AKM questions from the Ministry of Education and Culture. The results of the evaluation with a score of 4.13 for PkM participants showed that the participants were very satisfied with the training carried out.
