Enhancing Complex Problem-Solving Skills through STEM-Based Spatial Geometry E-Modules

Learning spatial geometry is still abstract thereby it is boring and less meaningful. As a result, learning outcomes in terms of skills and cognitive aspects become less optimal. Currently, students are no longer rely on textbooks as a learning resource. E-module is digitally designed learning resources that support independent learning. The e-module would be integrated with STEM approach. STEM learning activities are very important and need to be familiarized in learning, because the activities help prospective teachers in building the concepts learned, as well as to practice solving complex real-world problems. The method was research and development using the ADDIE model. The research subjects were 78 students who were prospective mathematics teachers of Mathematics Education Study Program, Universitas Tidar. Data were collected by using observation sheets, interview guides, questionnaires, and complex problem-solving tests. There are three main results from the study; first, STEM-based spatial geometry E-module is declared to be strongly valid according to expert validators. Second, based on student responses, this e-module is practical and the third, based on the results of complex problem-solving skills test, this STEM-based spatial geometry e-module is effective.

Thus, it is expected that students' problem-solving skills can be improved through the right learning approach and the use of relevant technology.

Teaching Mathematics based on Integrating Reading Strategies and Working Memory in Elementary School

This study strived to determine the effectiveness of integrative teaching of reading strategies and working memory on basic math and problem-solving skills. It is a quasi-experimental pretest-posttest study carried out on 50 second-graders from Chahashk Shandiz village in the academic year of 2020-2021 who were randomly selected by cluster sampling and randomly divided into experimental and control groups. The intervention was performed by cellphone software through virtual education in two steps. The experimental group underwent integrative training for 20 sessions, but the control group did not receive any intervention. Colored Progressive Matrices (1956) and a researcher-made story problem-solving and arithmetic skills test were used to collect data. Descriptive statistics (mean and standard deviation) and one-way multivariate analysis of covariance were used to analyze the data. The results showed that the integrative teaching of reading strategies and working memory enhanced the basic math skills, with an effect size of 0.67 in second-grade elementary students (P<0.001). According to the results, integrative teaching improved students' problem-solving skills but did not affect their skills in arithmetic operations. Therefore, second-grade elementary teachers can use this method to enhance their story problem-solving skills. Keywords: integrative teaching, reading strategies, working memory, basic math skills

The effects of Multiple Representation Method and Prior Knowledge Level on Problem Solving Skills and Cognitive Load

In this study, the effect of multiple representation method and prior knowledge level in solving ill-structured problems was investigated. Quasi-experimental and 2x2 (multiple representation method x prior knowledge level) factorial designs were used in the study. The study group consists of 39 undergraduate students. The dependent variables of the study were determined as problem solving skills, cognitive load, and permanence. The independent variables were considered as multiple representation method (step-by-step, holistic) and prior knowledge levels (novice, expert). Prior knowledge level test, problem solving skills test and cognitive load scale developed to measure the variables were used as data collection tools within the scope of the study. The data was analysed with two-way analysis of variance and independent groups t-test as the data obtained from the data collection tools exhibited normal distribution. In the results that were significant in the analysis, Cohen (d) in the independent groups t-tests and eta-square (η2) in the two-way analysis of variance were also shown.

In addition, it was concluded that the interaction of multiple representation method and prior knowledge level was statistically significant in terms of cognitive load variable. The findings supported the expertise reversal effect.
