This study examined the effectiveness of integrating congruence geometry into contextual numeracy learning to enhance junior high school students’ mathematical reasoning. A qualitative case study with quantitative support was conducted with 32 eighth-grade students and one mathematics teacher at a public school in West Java, Indonesia. The intervention included eight lessons embedding geometric transformations—reflection, rotation, and translation—into culturally relevant numeracy tasks such as batik and tiling designs. Data were collected through pretests, posttests, classroom observations, and interviews. Results showed a 43% improvement in contextual numeracy indicators and a significant increase in students’ ability to recognize congruent shapes, explain geometric reasoning, and apply transformations to real-life problems (t(31) = 6.42, p < 0.001). Observational and interview data revealed greater engagement, collaboration, and reduced mathematics anxiety. Findings support the four-dimensional numeracy framework (Goos et al., 2014) and Battista’s theory of geometric reasoning (2007), emphasizing that contextual and culturally grounded tasks foster conceptual understanding and motivation. The study concludes that contextualized geometry-based numeracy instruction effectively promotes students’ understanding, transfer of learning, and confidence, offering implications for developing culturally responsive mathematics curricula.

The research was conducted to improve mathematical literacy skills in the content of the growth phenomenon in class VIII C MTs Miftahul Huda through the development of learning videos based on the collaborative metacognition learning model assisted by CapCut. The research method used is the Research and Development Plomp model through three phases, namely preliminary analysis, prototyping, and assessment. Preliminary analysis produces the need for packaging mathematics learning that can invite students to understand mathematics material easily and solve contextual problems appropriately, so that students' mathematical literacy skills can be improved. Prototyping is carried out by designing a learning video that contains a video opening, problem presentation, problem solving, mathematical concept discovery, and video closing. The assessment was carried out by means of feasibility tests, practicality tests, and learning video effectiveness tests. The results of the video feasibility test from media experts were 0.97 and material experts were 0.97 which stated that they were very valid (feasible). Students rated the videos as very easy to use, useful, engaging, and encouraged metacognitive (practical) activities. Students' mathematical literacy increased in the medium category after using learning videos based on the collaborative metacognition learning model. Students need to get used to building mathematical concepts through contextual problem-solving even though their application takes a relatively long time. On this basis, advanced researchers need to consider the advantages of online learning that provide students with learning flexibility in building their mathematical understanding.

The teaching skills developed by prospective teachers are often repeated in different situations. Therefore, the optimal frequency of microteaching practices may influence both teaching skills and pedagogical content knowledge. This study used a cross-sectional design to compare teaching skills and pedagogical content knowledge among groups based on the frequency of microteaching practices conducted by prospective mathematics teachers. A total of 79 students were randomly selected from three universities in Yogyakarta that implemented microteaching with varying frequencies. These frequencies were classified into four categories: once, twice, three times, and more than three times. Teaching skills were assessed using observation sheets that outlined aspects such as explaining skills, asking questions, providing guidance, providing reinforcement, managing whiteboard use, and regulating body movement (non-verbal cues). Pedagogical content knowledge was measured using a test instrument. Data were analyzed using descriptive statistics and a one-way ANOVA test. The results showed that the frequency of practice has a different impact on teaching skills and pedagogical content knowledge. Prospective teachers who practiced microteaching more than three times significantly differed in their explaining skills, while their providing reinforcement differed significantly from those who practiced at least three times. Conversely, prospective teachers who practiced twice performed similar levels of skill in asking questions, whiteboard management, and regulating body movement compared to those who practiced more frequently. Pedagogical content knowledge of prospective teachers who practiced more than three times was significantly higher than that of those who practiced three or fewer times. These findings suggest that universities should carefully regulate the frequency of microteaching practices to optimize students' teaching skills and pedagogical content knowledge in mathematics education for those who aspire to become effective mathematics teachers. These findings suggest that universities should carefully regulate the frequency of microteaching practices to optimize students' teaching skills and pedagogical content knowledge in mathematics education students who aspire to become effective mathematics teachers. Keywords: teaching skills, microteaching, mathematics.

There are prospective applicants for Civil Servant Candidate (CPNS) positions, particularly for lecturer roles, who still feel uncertain about the formations they plan to apply for. This uncertainty stems from several factors, including the time and selection process, the number of available positions, the number of applicants, and the passing score threshold. In light of these considerations, this article seeks to explain how the webinar on tips for successfully choosing lecturer formations influenced the decisions of prospective CPNS applicants in selecting a formation. The webinar was conducted in three main phases: pre-implementation, implementation, and evaluation. The results of this community service initiative show that the webinar influenced the decisions of prospective CPNS lecturer applicants in choosing a formation. Before attending the webinar, only about 30.8% felt confident in their decision, but after attending, this percentage increased to around 93.3%. Participants who were initially unsure about their choices became more confident after the webinar, with two main outcomes. The first was that participants became more confident in their original choice, and the second was that participants felt confident to switch to another formation.
