Analyzing Learning Obstacle with Didactical Design Research on Three Dimensional Distance Material

he purpose of this study was to analyze the barriers to learning three-dimensional distance material using Didactical Design Research (DDR). The subjects of this study were two groups of class 12. The instruments used in this study were pretest (initial test) and post test (final test) which consisted of a test of the respondent’s ability, interview sheets, and observation notes. The data obtained were analyzed using three DDR steps: (1) didactic situation analysis by recontextualizing, repersonalizing, and developing didactic designs which include PDA (Pedagogical Didactic Anticipation); (2) metapedadidactic analysis by applying PDA; and (3) retrospective analysis linking didactic and metapedadidactic situations. The results showed that the identified learning obstacles can be anticipated by using PDA. The application of the didactic learning design shows that this design can be an alternative to third-dimensional distance learning in grade 12 because it can minimize student learning barriers that have been identified previously.

A Meta-Analysis on The Effect of Inquiry Learning Model on Students’ Mathematical Problem-Solving Skills

This study examines the effect of the inquiry learning model on the mathematical problem solving ability of students in Indonesia through meta-analysis. This study analyzed seven primary studies that met the inclusion criteria. The effect size index was calculated using the Hedges g equation and statistical analysis using comprehensive meta-analysis (CMA) software. Effect size testing is done by analyzing four characteristics, namely class of study, year of study, and sample size. Based on the results of the analysis using CMA, the inquiry learning model has a moderate effect (0.652) on the overall mathematical problem-solving skills of students. The use of the inquiry learning model is more effectively used in 8th-grade, in the range of 2015-2017 and 2018-2020, the sample size is less than or equal to 30. Thus, it can be seen that the inquiry learning model is useful in improving mathematical problem-solving skills.

What are The Difficulties in Learning Percentages? An Overview of Prospective Mathematics Teachers’ Strategies in Solving Percentage Problems

Many studies showed that teachers and prospective teachers have difficulty solving percentage problems. This research is a qualitative descriptive study that aims to investigate the prospective teachers’ strategies in solving problems on the topic of percentages. A total of 250 students majoring in Mathematics Education and Primary Education at IAIN Syekh Nurjati and IAIN Pekalongan were purposively selected to participate in this study. The results showed that only less than half of the participants (40.1%) could give the correct answer. Qualitative data on the strategies used by prospective teachers on the percent question show that (1) teacher candidates ignore the importance of the % symbol and consider the % symbol only as a unit of measurement, (2) teacher candidates ignore the essential role of the reference quantity in the percent question, (3 ) teacher candidates are not used to solving percent problems related to determining initial values before discounts and assume that any percent problem can be solved using multiplication or division.

Visual-spatial Skills and Mathematics Content Conceptualisation for Pre-service Teachers

Empirical evidence in literature identified significant association between spatial ability and educational performance particularly in science, technology, engineering and mathematics (STEM). The purpose of this study was to explore pre-service teachers’ spatial skills in solving mathematics problems, in the context of coordinate geometry. It is envisaged that spatial skills allow for the perception of visual information and, therefore, spatial cognition has been considered as a key skill in teaching mathematics. However, literature asserts that teachers are ill prepared to teach mathematics, hence there is limited use and misuse of spatial skills in teaching the subject. This study, therefore, examines the spatial orientation of pre-service teachers in teaching coordinate geometry. This is a mixed methods study in which pre-service teachers answered a coordinate geometry test to explore their content knowledge and their ability to interpret, analyse and apply visual spatial models to solve mathematical problems in coordinate geometry. The study established that the spatial orientation skills of pre-service teachers determine their performance in mathematics, especially coordinate geometry.
