Students in the 21st-century era must have many skills. There needs to be learning that supports an independent curriculum and project-based learning. Meanwhile, schools still carry out their learning activities using the lecture method, which is less meaningful and has yet to explore students' abilities fully. STEM is a skill and knowledge acquired simultaneously by students. The aims of this study are that researchers want to obtain deeper information about 1) the background of STEM-based learning at SDI Aisyiyah, 2) the implementation of STEM-based learning at SDI Aisyiyah, and 3) the skills students acquire during STEM-based learning at SDI Aisyiyah. Researchers want to obtain more in-depth information about the background of learning in the school, the application of STEM learning in the school, and the skills that can be formed from STEM-based learning. This research uses a qualitative method whose data processing uses NVivo12. Nvivo 12 is the latest version of the application for processing qualitative research data. The research findings support 21st-century learning, project learning during a pandemic, implementing an independent curriculum, providing STEM training, creating fun learning and creating a low-cost STEM culture. STEM learning is held once a week. The syntax in STEM learning at SDI Aisyiyah is as follows: 1. The teacher selects and breaks down KD/TP in learning, 2. Giving triggering questions or problems, 3. Finding solutions or problem-solving by teachers and students, 4. Product design, 5. Product presentation or presentation, 6. Product correction and evaluation, and the last is product revision. Some of the skills that can be formed from STEM learning at SDI Aisyiyah are being able to work together, being able to think complexly, having an artistic spirit, being a more communicative, more creative child, being independent, etc.

Information processing theory is a theory that can explain students' thinking processes in problem-solving. Effective problem-solving requires a good thinking process. Thus, exploring students' thinking processes will help in understanding the causes of students' mistakes so that they can be prevented and enhance students' problem-solving eventually. In line with that, this research aims to analyze students' thinking processes in solving powers and root forms problem (in mathematics) based on information processing theory. This case method research with a qualitative approach was carried out at SMP Laboratorium Universitas Negeri Malang (UM) involving two subjects. The findings show that for both student who answer correctly and student who answer incorrectly, the thinking process begins with the entry of stimuli into sensory memory which is then selected through selective attention to obtain perception. The information is then passed to short-term memory. The difference in their thinking processes lies in the retrieval process. The student who answered correctly succeeded in solving the problem correctly even though he experienced a forgotten lost while the student who answered incorrectly experienced misperceptions caused by a forgotten lost which resulted in the strategy execution and the final answer being incorrect.

Translation is a process of transforming information from source representation to target representation. The translation process is described in four activities, such as unpacking the source, preliminary coordination, constructing the target, and determining equivalence. This study aims to analyze and describe the translation process of mathematical representations from verbal to symbolic in UM Mathematics S1 students in solving statistics on variance and standard deviation material. The instruments used were translation test questions and interview guidelines. Data analysis focused on four translation activities which were then categorized (high, medium, low). The results of the research percentage show that 78.58 percent of students experience difficulties in translating representations from verbal to symbolic in statistical problems. This is because students make mistakes in interpretation and implementation. While 21.42 percent of students succeeded in translating representations in solving the variance and standard deviation problems that have been presented. In terms of categorization, 21.42 percent of students belong to the high category, 39.29 percent of students belong to the medium category, and 39.29 percent of students belong to the low category. At this stage, the researcher obtained 28 student subjects for further analysis through 4 (four) stages of translation.

Reflective thinking begins with repeated confusion and evaluation to solve a problem. There are four aspects to reflective thinking, namely techniques, monitoring, insight, and conceptualization. However, the problem-solvers’ reflective thinking characteristics in mathematical problems have not been discovered. The study describes the reflective thinking characteristics of proficient mathematics prospective teachers based on four aspects. The qualitative research was conducted at Universitas Muhammadiyah Surakarta with a total of 64 reflective thinkers. Data collected by test, observation sheets, and interview methods. The tests were administered twice. The instruments developed has been through the validation process and declared valid. Data analyzed through the stages of reduction, presentation, and verification. We successfully conclude that proficient mathematics prospective teachers have complete and consistent reflective thinking characteristics. Further research can be focused on the characteristics of reflective thinking based on another aspect.

Proof constructing is the process of justifying a claim using the methods and concepts of proof to produce mathematical proof. Proof constructing is also an aspect of proof, and is often the only way to assess student performance. However, proof construction is still a constant problem (difficulty) for every student. The cause of this difficulty is not only because of the content of proof in textbooks/sources, over-reliance on examples, understanding, underlying logic, and the ability to use proof writing strategies, but also due to the lack of proof discussion activities that train students to understand and answer proof practice questions, give proof reasoning against the proof that has been constructed, and validating own and other colleagues' answers. Thus, this study aims to develop a valid and practical ACERA (Activities, Classroom Discussion, Exercises, Reason, and Audience) learning model and has a potential effect on students' ability to proof construction. This study uses research design research development methods in three stages, namely the preliminary stage, the model development stage and the assessment stage. The research subjects were 23 students of the Mathematics Education study program at the University of Mataram. The development of the ACERA model offers an alternative solution to reduce the difficulty of proof construction, thus enabling this model to have characteristics that are valid, practical and have a potential effect in increasing the productivity of student proof construction.

As the Indonesian National Curriculum (INC), the Merdeka curriculum was implemented in response to students' difficulties in comprehending and utilizing basic mathematics, contributing to low numeracy skills. This study investigated mathematics teachers' perceptions in Indonesia concerning the effectiveness of INC and the supporting programs, such as the National Assessment (NA) and Pancasila Student Profile (PSP), in improving students' numeracy skills. It also aimed to identify mathematics teachers' challenges in integrating numeracy skills into the curriculum and these programs. A mixed-method study with a sequential explanatory design was used to achieve this objective. The data collection was carried out through quantitative and qualitative approaches. Closed questionnaires were explicitly used for quantitative data, while open questionnaires and interviews were used for qualitative data. Inferential statistics were used to analyze the quantitative data and a thematic analysis for qualitative data. The quantitative results showed that most teachers positively perceived the effectiveness of INC and the programs in empowering students' numeracy skills. The implementation of INC and PSP significantly influenced the empowerment of numeracy skills. The qualitative analysis provided an in-depth exploration of teachers' perceptions and the challenges faced in promoting numeracy skills in implementing INC and the programs.
