In the 2013 curriculum, mathematics learning is more directed at higher-order thinking skills (HOTS). HOTS are observed from the abilities of students in solving HOTS type of questions. However, students still make mistakes in solving this type of questions, especially the statistics questions. The students’ errors in solving HOTS type of statistical questions need to be investigated, particularly on the types and causes. This study aimed to describe the errors made by students in solving HOTS type of statistical questions. This study was conducted at SMP Negeri 1 Selopuro, Blitar City Year Academic 2019/2020. This study used descriptive qualitative approach. The subjects were three students of 8th grade B. The instruments in this study were tests, interviews, and documentations. Based on the results of the data analysis, it can be concluded that: (1) reading errors were due to the inability of the students to understand the information in the questions; (2) comprehension errors were due to incomprehension of the students on what to look for in the questions; (3) transformation errors were in the form of inability in generating functions/methods to solve the questions; (4) processing skill errors were in the form of misconnection and misconception; and (5) errors in writing the final answers were due to drawing wrong conclusions.

The purpose of this study was to determine the types of student errors in trigonometry material based on Newman's theory and the causes of these errors. This study uses a qualitative approach and descriptive research type. Research instruments in the form of tests, interviews, and documentation. In this study, 3 subjects with different abilities were taken, namely students with high abilities, students with moderate abilities and students with low abilities. Based on the results of the study, it was concluded that: the most frequent types of errors made by the first students were comprehension errors or errors in understanding information. Second, process skill errors or calculation process skill errors. Third, the transformation error or error determines the formula where students are wrong in writing the formula to be used. Fourth, encoding errors. The causative factor is that students do not understand the concept of trigonometry material and do not master the concept so that students are unable to relate it to the previous material. Students do not know the problem-solving techniques, are not careful in working and are in a hurry or cannot take advantage of the time allotted.

Mathematics learning in schools often faces challenges such as student noise during explanations, low learning outcomes, and limited student engagement in the learning process. To address these issues, a student-centered learning model supported by digital technology is needed. This study employed instruments including student activity observation sheets, teacher activity observation sheets, and student learning achievement tests. Data collection techniques in this research involved observation and student learning achievement tests. The data analysis technique was conducted by compiling data from all instruments. The aim of this study was to describe the implementation of the problem-based learning model assisted by the Wordwall interactive media on the topic of similarity in Grade VII at MTs. Maftahul Ulum. The method used was Classroom Action Research (CAR). The results showed that student activity obtained an average score of 3.45 in the active category, while teacher activity obtained an average score of 3.58 in the very active category; both met the success criteria. In the student learning achievement test, the highest score achieved was 98, the lowest score was 55, and the average score was 83.05 with a mastery level of 77.77% (14 students passed out of 18). Based on these results, it can be concluded that the implementation of problem-based learning assisted by Wordwall in the topic of similarity, particularly the subtopic of the relationship between angles and similarity in Grade VII at MTs. Maftahul Ulum Karangsono, has met the success criteria

Numeracy is not merely the ability to perform calculations, rather, it is the capacity to understand, interpret, and communicate mathematically rich information in real world contexts. Strengthening numeracy is not the sole responsibility of mathematics teachers. It requires collaboration across all subject areas. National and international assessments consistently indicate that the numeracy skills of Indonesian students have not improved significantly and, in some cases, have shown a declining trend. Preliminary observations revealed that, although SMK Negeri 3 Blitar had conducted activities to raise awareness of numeracy literacy, it lacked established best practices for developing numeracy-based teaching modules and assessments. Consequently, a collaborative workshop was organized at SMK Negeri 3 Blitar to provide guidance in the development of these materials. This initiative was carried out in collaboration with the Blitar Campus (PSDKU) of Universitas PGRI Adi Buana Surabaya and aimed to enhance teachers’ understanding of numeracy while supporting the production of numeracy based teaching modules and assessments. The program employed a collaborative workshop approach consisting of four stages: preparation, implementation, evaluation, and reporting. A total of forty four teachers from various subject areas participated in the two day event, which included presentations, sharing sessions, and group based practical activities focused on developing teaching modules and assessments. The evaluation indicated that 84% of participants achieved a high level of understanding of fundamental numeracy literacy concepts, and all groups successfully produced numeracy based teaching modules and assessments. Nevertheless, participants’ ability to design assessments still requires further improvement, as only 39% reached the high-proficiency category. Therefore, continued assistance through more intensive hands on training is recommended.

The purpose of this study is to describe the types of errors made by eighth-grade students at SMPN 2 Blitar. This study employs a descriptive qualitative approach. The data, consisting of worksheet assignments and interviews, were analyzed using purposive sampling and grouped into three ability categories high, moderate, and low based on Ennis’s criteria for critical thinking: Focus, Reason, Inference, Situation, Clarity, and Overview. The results revealed that the three selected research subjects exhibited different error patterns. The high-ability subject met most of the indicators but made errors on the Overview indicator. The moderate-ability subject made errors on the Reason, Inference, Situation, Clarity, and Overview indicators. In contrast, the low-ability subject made errors on all of Ennis’s indicators.
