MATHEMATICS TEACHERS’ ANXIETY IN TEACHING AND LEARNING PROCESS: A LITERATURE REVIEW
No full textOver the last few decades, many studies have placed attention on math anxiety in students, but math teachers can also experience anxiety that requires the attention. Math teachers can experience the anxiety in the form of math anxiety and math teaching anxiety, which can affect the learning process of mathematics. The purpose of this study is to identify the factors that cause math anxiety and math teaching anxiety in teachers. The method used in this research is Systematic Literature Review (SLR) with a survey-based descriptive approach through analysis the articles that fulfilled the inclution criteria, namely (1) published during the last ten years (2013-2022), (2) written in Indonesian or English, (3) indexed by Scopus or Sinta, which are browsed on the Google Scholar, ERIC, and Garuda database using the keywords “teachers’ math anxiety" and “teacher’s math teaching anxiety”. The results showed that mathematics teachers who experience mathematics anxiety in the form of feelings of worry and discomfort when thinking or doing something related to mathematics, this is caused by a low level of mathematics knowledge and self-confidence, while mathematics teaching anxiety causes worry and feeling uncomfortable when going to or teaching mathematics, this is caused by several factors such as experiencing mathematics anxiety, low mastery of learning technology, low levels of self-confidence, and unsupportive learning infrastructure
DEVELOPMENT OF CLOPEDIMATIC LEARNING MEDIA WITH REALISTIC MATHEMATICS APPROACH BASED ON MADURA’S LOCAL WISDOM
Get PDFThe low student learning outcomes in the measurement material can be caused by the tendency of teachers to only transfer their knowledge to students' minds so that students are passive, and not critical. One learning approach that pays attention to this situation is a realistic mathematical approach based on Madura local wisdom. Students are presented with contextual problems, namely problems related to measurements, so that they are trained to get used to solving problems in their daily lives. To support this realistic mathematics approach, a clopedimatics-based learning media will be designed as a substitute for textbooks used by students. Clopedimatics is a form of print media that is compiled based on the concept of compiling an Encyclopedia and designed to help students master the measurement material and is associated with non-standard units of measurement used by the Madurese community. This type of research is development research that uses a 4-D model but has been modified to 3-D, namely defining, designing, and developing. The conclusions of this study are development of clopedimatic learning media with a realistic mathematics approach based on Madurese local wisdom in the measurement material at SDN Barkot 1 Pamekasan meets the valid, practical, and effective criteria
