This study aims to diagnose students' errors in finding the area using integration. Errors can be seen from the student completion steps that are not correct. This type of research is qualitative research. The applied instruments were diagnostic tests and interview guidelines. The subjects consisted of Universitas Muhammadiyah Parepare students from Mathematics Education Study Program. Then, the researchers selected three subjects from 23 subjects that committed various errors. The results showed that the errors were: (1) Conceptual error, (a) substitution errors for the lower bound and upper bound, (b) misunderstanding in drawing the graph of a function. (2) Procedural errors dealing with incorrect calculation operation. (3) Final solution errors dealing with incapability to find the accurate answers based on the questions. Therefore, it is necessary to diagnose errors made by students using integration to calculate the area so that for lecturers, it becomes a reference to minimize errors made by students and find solutions for the mistakes made.

Literacy is an important aspect in basic education because it determines learning success at the next level. Literacy is not only limited to reading and writing, but also the ability to understand, process and utilize information. However, low motivation, limitations in utilizing reading materials and supporting learning environments are still obstacles. This service program is an effort to strengthen literacy skills among students at SD Negeri 15 Parepare which is carried out from August to December. This activity aims to strengthen students' literacy skills by creating learning media and mentoring. The media created are literacy trees, reading corners, and library improvements with the program name "Pintu Ilmu". This activity is complemented by mentoring students and optimizing the library through the "Jelajah Pustaka" and "Literacy Development" programs. Evaluation was carried out using pretest and posttest to measure the average increase in students' literacy skills from 51.84 to 68.95. These results prove that the media-based and mentoring literacy strengthening program is effective in improving the literacy skills of elementary school students.

Mathematical reasoning ability is one of the essential competencies that need to be developed in 21st-century mathematics learning. However, the results of preliminary studies indicate that this ability is still in the moderate category, with the main weakness in the aspect of mathematical manipulation. This study aims to analyze the impact of the use of interactive digital media on improving students' mathematical reasoning abilities, as well as identifying the most affected indicators. The study used a pre-test - post-test design with a population of six sixth-semester students of the Mathematics Education Study Program, Universitas Muhammadiyah Pare-pare. The research instrument was a descriptive test designed to measure three indicators of mathematical reasoning, namely proposing conjectures, presenting mathematical statements, and performing mathematical manipulation. The results of the descriptive analysis showed an increase in the average score from 58.33 (medium category) in the pre-test to 80.09 (high category) in the post-test, with a normalized gain of 0.52 which is in the medium category. The decrease in the standard deviation from 7.86 to 5.67 indicates that student achievement became more homogeneous after the treatment. Analysis per indicator showed that the largest increase occurred in the indicator of proposing conjectures (27.78 points), followed by presenting mathematical statements (23.61 points), while the indicator of performing mathematical manipulation experienced the lowest increase (13.89 points). These findings confirm that interactive digital media is more effective in strengthening high-level mathematical reasoning skills based on visual and conceptual representations, while procedural skills still require additional manual practice support. Overall, this study concludes that the integration of interactive digital media has the potential to be an effective pedagogical strategy for improving students' mathematical reasoning abilities, while reducing individual variation in achievement. The practical implication of this study is the need for a balanced learning design, combining the use of interactive digital media and conventional practice strategies to comprehensively strengthen all aspects of mathematical reasoning

The study evaluates whether and to what extent the Teaching at the Right Level (TaRL) intervention improves students’ learning in mathematics across cognitive, affective, and psychomotor domains. This study employed a pre-experimental one-group pre-test/post-test design, in which a single cohort of 35 Grade XI students at Senior High School I, Takalar, South Sulawesi, Indonesia, was assessed before and after the implementation of the TaRL approach. Data were gathered using pre- and post-tests to measure cognitive improvement. The cognitive, affective, and psychomotor domains were assessed with structured observation sheets using a five-point Likert scale, which were then transformed to a 0-100 scale for clarity of interpretation. The result showed a significant increase in students’ cognitive achievement, with the pre-test and post-test means of 83.42 and 93.22, respectively. Although the initial score was relatively high due to students’ prior exposure to similar mathematical content, the statistical results confirmed a meaningful improvement beyond the baseline understanding. Observations of the affective domain revealed notable positive shifts; students demonstrated higher motivation, increased confidence in problem-solving, and more active participation during class activities, as reflected in an average converted score of 95.31. In the psychomotor domain, the mean score of 93.21 demonstrated students’ enhanced ability to apply mathematical concepts in practical contexts through active engagement. These findings suggest that the Teaching at the Right Level (TaRL) approach effectively enhances students’ learning outcomes within the studied context by promoting active, differentiated, and student-centered learning experiences. Since the study was conducted at a single institution with a small sample, additional research with larger populations and diverse educational contexts is necessary to substantiate and generalize these findings. Keywords: affective, cognitive, mathematics, psychomotor, teaching at the right level (TaRL).
