This research aims to improve the natural science (science) learning outcomes of class VI students at UPT SPF SD Inpres Kampus Ikip through the application of differentiated learning. Differentiated learning is a teaching strategy that is tailored to students' needs, abilities, interests and learning styles, so that each individual can learn optimally. This classroom action research (PTK) was carried out in two cycles, each consisting of planning, implementation, observation and reflection stages. Data is collected through learning results tests, observations, and interviews to measure changes that occur in student learning outcomes. The research results show an increase in student learning outcomes in each cycle. In the first cycle, student learning outcomes showed quite significant improvements, but some students still needed adjustments in the learning methods applied. In the second cycle, learning outcomes increased more sharply along with adjustments made in differentiated learning strategies, such as the use of more diverse media and activities as well as dividing study groups according to students' ability levels. Based on these findings, the application of differentiated learning has proven to be effective in improving science learning outcomes for grade VI students at UPT SPF SD Inpres Kampus Ikip.

This study aims to describe students' errors in solving mathematics problems on the topic of fractions based on Newman’s Error Analysis. The background of this research is the low learning outcomes of fifth-grade students in the fractions topic at SD Inpres Tamamaung III. This research employs a descriptive qualitative method. Data were collected through written tests and interviews. Out of 29 fifth-grade students, three subjects were selected based on their level of error according to Newman’s procedure, categorized into high, medium, and low error levels. The student with a high level of error made several mistakes, including comprehension errors, transformation errors, process skills errors, and errors in writing the final answer. The student with a medium level of error committed transformation errors, process skills errors, and final answer writing errors. Meanwhile, the student categorized as having a low level of error made no mistakes and answered the questions correctly. The results of the study indicate that most students made errors in solving word problems based on Newman’s procedure, including reading errors, comprehension errors, transformation errors, process skills errors, and final answer writing errors. To validate the test results, the researcher conducted interviews with the three selected subjects representing the different levels of errors. These errors were caused by students’ lack of accuracy, difficulty in understanding concepts, and a tendency to rush through the tasks.

This study aims to determine how much the ability to calculate mathematics through flashcard learning media and to determine the effect of flashcard learning media on the ability to calculate in mathematics subjects. This type of research is Pre-experimental research. With the research design is One Group Pretest-Posttest Design. The population of this study was all students of grade I UPT SPF SD Inpres Bontomanai, which consists of two classes namely class IA and IB. While the sample used in this study was simple cluster sampling. Simple cluster sampling is a random sampling technique from various clusters in a population. The sample taken in this study was class IA as many as 28 students. The research instrument used was a pretest and posttest test sheet. The data analysis technique used was descriptive statistical data analysis and inferential data analysis. The results of the study showed that the average score of the initial ability test before the application of flashcard learning media (pretest) was 39.28 with a standard deviation of 17.089. From these results, 2 (7.12%) students completed the test and 26 (92.85%) students did not complete it, while the average score after the application of flashcard learning media (posttest) was 84.10 with a standard deviation of 10.71. From these results, 3 (10.71%) students did not complete the test and 25 (89.28%) students completed the test, this means that classical completeness was achieved. This shows that flashcard learning media has a positive effect on improving students' counting abilities. The results of the Paired Sample T-Test test show that the significance value (2-tailed) is <0.000. This significance value is much smaller than the significance level of 0.05, so H0 is rejected and H1 is accepted. Thus, H0 is rejected and H1 is accepted, indicating that there is a significant difference in students' calculation ability before and after treatment. It can be concluded that the application of flashcard learning media has an effect on improving students' calculation ability.

Real Analysis is often a gatekeeper course in mathematics education, marking the difficult transition from computational calculus to formal axiomatic proof. Prospective mathematics teachers frequently struggle to construct rigorous proofs, even for fundamental properties. This study employs Newman's Error Analysis (NEA) to analyze the epistemological obstacles underlying these struggles. This descriptive qualitative case study involved 15 fifth-semester undergraduates at Universitas Muhammadiyah Makassar who completed a diagnostic proof test on field properties. Analysis of student work revealed that none made errors at the 'Reading' stage. Instead, errors clustered at higher cognitive stages: 3 students exhibited Comprehension errors, 5 made Transformation errors, 4 showed Process Skills errors, and 3 made Encoding errors. From this cohort, four subjects, each exemplifying one of these non-reading error types, were selected for in-depth semi-structured interviews. The findings indicate a hierarchical breakdown in proof construction specifically for the theorem: "If a ≠ 0 and a ∈ ℝ, prove that ≠ 0." Students either failed to translate verbal understanding into explicit premises (Comprehension), could not operationalize an indirect proof strategy (Transformation), neglected to justify algebraic steps with axioms (Process Skills), or omitted formal concluding statements (Encoding). The study concludes that errors often perceived as "carelessness" can be symptoms of deeper epistemological obstacles, such as viewing proof as a computational ritual rather than a formal, communicative argument. These findings underscore the need for explicit instruction on proof mechanics and structure, even when students possess correct mathematical intuition.
