  Abstraction ability in mathematics is very important because it can be used to describe mathematical concepts in a mathematical problem. One way to help students develop mathematical abstraction skills is to apply the Eliciting Activities Model (MEAs). The purpose of this study was to determine the increase in mathematical abstraction skills between students who received mathematics learning with MEAs compared to the expository model, and to determine students' attitudes towards mathematics learning with MEAs. The method used in this research is quasi-experimental. The population in this study were students of class VIII SMP Negeri 16 Bandung with a sample of two classes from all available class VIII. The instruments used are mathematical abstraction ability test instruments, questionnaires, observation sheets, and students' daily journals. The results showed that the improvement of mathematical abstraction skills with MEAs was better than students who received mathematics learning using the expository model. In addition, students gave a positive response to learning mathematics with MEAs.

The ability of mathematical representation is one of the abilities that must be possessed by students in learning mathematics. In fact, students 'mathematical representation ability is still relatively low, so we need a learning model that can improve students' mathematical representation abilities, namely Model Eliciting Activities (MEA) with STAD type. The purpose of this study is to compare the mathematical representation ability of students taught using MEA with STAD type and those taught with conventional learning. The approach to be used is a quantitative approach with a quasi-experimental research method and using a control group pretest-posttest design. The population in this study were all VII grade students. Sampling was done using simple random sampling, which consisted of two classes, class VII1 as the experimental class and class VII2 as the control class. Data collection is used by using a mathematical representation ability test sheet. The data analysis technique used is independent t-test. Based on these analysis it can be concluded that the mathematical representation ability of students taught using MEA with STAD type is better than conventional learning.

In this paper, we explore the challenges experienced by a group of Primary 5 to 6 (age 12–14) students as they engaged in a series of problem-solving tasks through block-based programming. The challenges were analysed according to a taxonomy focusing on the presence of computational thinking (CT) elements in mathematics contexts: preparing problems, programming, create computational abstractions, as well as troubleshooting and debugging. Our results suggested that the challenges experienced by students were compounded by both having to learn the CT-based environment as well as to apply mathematical concepts and problem solving in that environment. Possible explanations for the observed challenges stemming from differences between CT and mathematical thinking are discussed in detail, along with suggestions towards improving the effectiveness of integrating CT into mathematics learning. This study provides evidence-based directions towards enriching mathematics education with computation.
