Abstract

This study aims to determine the improvement of students' mathematical communication skills using metacognitive strategies. The method used was quasi-experimental with a non-randomized control group post-test control group design. The sample of this study was the junior high school students of class VIIA and VIIB as experimental and control classes with many students in each class 19 and 17 people. The instrument used was a test of mathematical communication skills. The results showed that students' mathematical communication skills using metacognitive strategies were better than students who used conventional learning. Thus the metacognitive strategy can be used as an alternative strategy to improve students' mathematical communication skills.

Abstract

The purpose of this study was to determine differences in students' mathematical communication skills based on gender with learning using metacognitive strategies. This research method is a quasi-experimental design using a pretest-posttest control group design. The sampling technique used was saturated sampling which consisted of 19 male students as the first experimental group and 17 female students as the second experimental group. The instrument used was in the form of a five-point essay test to measure the aspects of students' mathematical communication skills after being given a treatment, namely learning using metacognitive strategies. The pre-test mean score shows that female students are higher than male students, on the contrary, the average score of the post-test results, it is known that male students are higher. The data were analyzed using the t-test, it was concluded that there was a significant difference between the mathematical abilities of male and female students. This difference is consistent with several previous research results, although not a few studies also state that there is no significant difference between students' academic abilities based on gender.

Abstract

The development of digital technology has brought significant changes in education, including in the learning process. However, teachers in remote areas such as Leihitu Barat District, Central Maluku, still face limitations in digital competence and infrastructure, which hinder the optimal use of educational technology. Based on these conditions, this community service program was carried out with the aim of improving teachers’ digital competence through training on the use of the Edukati-based Learning Management System (LMS). The activities involved several stages, including preparation, face-to-face training, hands-on practice using the LMS, online mentoring after the training, and evaluation through pre-test and post-test. The results indicated a significant improvement in participants’ understanding and skills. Before the training, all teachers had no knowledge of LMS and no prior experience in using it. After the training, all participants understood the basic functions of LMS, and 75% were able to operate Edukati’s key features, such as creating digital classes, uploading materials, and designing learning assessments. Teachers’ readiness level increased from 4.2% (not ready) to 82.1% (ready). Nevertheless, limited devices, unstable internet access, and the absence of technical staff remain challenges in implementation. Teachers’ enthusiasm, the support of a WhatsApp community, and the openness of partner schools to digital innovation provide opportunities for program sustainability. Therefore, the Edukati LMS training proved effective in improving teachers’ digital literacy and is essential as a strategic step to strengthen digital culture in education, particularly in remote areas

Abstract

Representational transformation skills significantly influence students' success in problem-solving. Students who struggle with representational transformation skills are often less adept at utilizing mathematical ideas and relationships, and vice versa. Therefore, this study used a qualitative, descriptive-interpretive approach to examine students' semiotic representation skills when solving mathematical problems. The research was conducted in a Year 9 classroom in a public school in Bandung, Indonesia, with 30 participants divided into high, middle, and low-ability groups based on their level of mathematical ability. Data was collected using both test and interview techniques. The results indicated that students in the high and middle ability groups had adequate skills in algebraic treatment and conversion from algebra to geometry and verbal expression skills for constructing algebraic expressions and converting verbal statements into mathematical equations. In contrast, the low-ability group demonstrated a lack of semiotic representation skills in problem-solving. These findings highlight the importance of transformation and conversion skills in mathematical problem-solving activities and can be valuable information for teachers and observers of mathematics education.

Abstract

Students' thinking styles are important factors for teachers to accommodate all types of students' thinking styles in a learning approach. Therefore, this study aims to determine students' mathematical problem-solving skills from their respective thinking styles using a metacognitive approach. The sample in this study was 60 students of class XII Madrasah Aliyah Negeri Ambon consisting of 31 Mathematics IPA-1 classes as the experimental class and 29 Mathematics IPA-2 classes as the control class. This research is a quasi-experimental study with a pretest-posttest control group design. The research instruments used were tests (pre-test and post-test) and the thinking style instrument. The data were tested by univariate test and t-test. The experimental class concluded; There are differences in the improvement of students' mathematical problem-solving abilities between groups of thinking styles and there is an influence of thinking styles on problem-solving abilities. While in the control class; There is no difference in increasing students' mathematical problem-solving skills between groups of thinking styles, nor is there any influence of thinking styles on problem-solving abilities. These results illustrate that students' mathematical problem-solving skills can be influenced by thinking styles as a result of the learning approach used, namely the metacognitive approach.

The program methods included coordination and needs analysis, socialization, interactive lectures, demonstrations, hands-on practice, product presentation, evaluation, and follow-up reflection. Data were collected using a pretest-posttest on AR-based digital learning media understanding, an Assemblr Edu project performance rubric, observation sheets, and a participant satisfaction questionnaire. The results showed that teachers' average understanding increased from 55.8% to 84.1% with an N-gain score of 0.64. The average technical performance score for developing AR projects reached 80.1, and 26 participants or 86.7% successfully published their AR projects independently through links or QR codes. Participant satisfaction reached an average of 4.42 out of 5.00, indicating a very satisfied category. Teachers' products included AR media for fractions, solid geometry, arithmetic operations, animal life cycles, and a simple solar system.

Abstract

This study aims to uncover the multidimensional error patterns of students in solving algebra problems from the perspective of semiotic representation at various ability levels. This study used a qualitative approach involving 30 seventh-grade junior high school students. The research subjects were selected by purposive sampling, then six students were determined representing the high, medium, and low ability categories. Data were obtained through written tests and interviews, then analyzed based on Nolting's error classification, which includes misread direction error, careless error, concept error, application error, test procedure error, and transformation error. The results showed that students at all ability levels experienced difficulties in converting between representations (transformation error), especially from verbal to symbolic (algebraic expression) and symbolic to geometric expression. High-ability students were able to reason symbolically but failed to connect it to the visual context (graphical expression), while medium-ability students tended to use trial and error strategies that resulted in application errors. Students in the low-ability group showed concept errors and fundamental representation errors (transformation errors). In general, transformation errors were the most dominant type of error, followed by concept errors and application errors. These findings indicate that algebra learning needs to be designed by integrating various semiotic representations so that students' conceptual understanding can develop more deeply.
