Abstract

The rapid development of technology demands an increase in the competence of Human Resources. Utilization of Information Technology and Computers for Vocational High School level learning is very vital to enter the era of the industrial revolution 4.0. This activity helps schools prepare for the digitalized system process so that they can produce quality graduates who are able to compete globally by mastering technology. The purpose of this activity is to provide knowledge to teachers at Private Vocational School 2 Nurhasanah Medan regarding the manufacture of digital-based teaching materials and provide skills to teachers at Private Vocational School 2 Nurhasanah Medan in making digital teaching materials by utilizing the flipsnack application. The target audience for this activity was 20 teachers at SMK 2 Nurhasanah Medan. Two problems can be solved through ICT mastery workshops (training and mentoring). This training was held from August to November 2022. The results of the activity showed that the participation of the training participants showed satisfactory results where 90% of the participants had attended the training activities; all activities have met the set achievement targets, and The mentoring activities carried out have been able to improve the teacher's ability to compile and make teaching materials and materials for learning

Abstract

Abductive reasoning is a problem-solving method that allows for the creation of hypotheses based on incomplete information. In this article, we explore the potential of using abductive reasoning to help solve algebraic problems. We begin by providing an overview of abductive reasoning and its key features. We then present a case study in which we apply abductive reasoning to a specific algebraic problem. Our results demonstrate the effectiveness of using abductive reasoning to generate new hypotheses and ultimately solve the problem. Finally, we discuss the implications of our findings for the teaching and learning of algebra, as well as potential future research directions in this area. Based on several observations, some students experienced difficulties in problem-solving activities. Their inability may be caused by the complexity of making conclusions from the facts provided in problem-solving. Student failure in problem-solving shows that the importance of problem-solving needs to be better taught in learning mathematics. One prominent factor that can support problem-solving in practice is reasoning. Therefore, increasing reasoning and proof is a fundamental aspect of learning mathematics. Theoretically, and developing Abductive Reasoning as teaching material for Linear Algebra courses to find solutions to algebraic problems in mathematics learning activities.

Abstract

This study aims to analyze the Computational Thinking (CT) abilities of prospective mathematics teacher students enrolled in the Teacher Professional Education Program at Universitas Islam Sumatera Utara. Using a descriptive quantitative approach, CT abilities were examined based on four main indicators: decomposition, pattern recognition, abstraction, and algorithmic thinking. Data were collected through contextual open-ended tests, perception questionnaires, and limited interviews involving 24 PPG students. The results showed that, in general, students' CT abilities fell into the moderate category, with the highest achievement in pattern recognition and the lowest in abstraction. Most students had never received explicit instruction in CT, yet acknowledged that this approach helped them solve mathematical problems more systematically. These findings highlight the importance of explicitly integrating CT skills into mathematics education curricula through problem-based and digital literacy-oriented learning approaches. The study recommends strengthening instructional strategies to develop students’ systematic and logical thinking abilities as future mathematics educators.

Abstract

This study aims to analyse the mindset of pupils at Dharma Pancasila Junior High School in dealing with various academic and non-academic problems. The study employed a qualitative descriptive approach, involving pupils in Years 7, 8 and 9 as research subjects. Data collection techniques included observation, in-depth interviews, questionnaires and documentation. Data analysis utilised the Miles, Huberman and Saldaña model, which comprises data reduction, data presentation and drawing conclusions. The results of the study indicate that the majority of pupils exhibited characteristics of a growth mindset, such as a willingness to learn from mistakes, striving to find solutions, and accepting criticism as feedback for personal development. However, a number of pupils were still found to exhibit a fixed mindset, characterised by a tendency to give up easily when faced with difficulties, viewing ability as fixed, and avoiding challenges for fear of failure. Factors influencing pupils’ mindsets included the family environment, school culture, teacher support, peers, and previous learning experiences. This study recommends the implementation of teaching methods that foster a growth mindset through constructive feedback, reflective learning, and character building.

Abstract

Abstrak Keterampilan literasi dan numerasi sangat penting untuk mencapai potensi penuh dalam menjalani kehidupan yang bermakna dan produktif. Penelitian ini bertujuan mengkaji efektivitas Problem-Based Learning (PBL) dalam meningkatkan literasi dan numerasi siswa sekolah dasar di Kota Medan. Menggunakan desain quasi-eksperimen, sampel terdiri dari 37 siswa kelompok eksperimen (PBL) dan 35 siswa kelompok kontrol (konvensional). Data dikumpulkan melalui tes prior knowledge (PK), literasi, dan numerasi, dianalisis dengan ANOVA dua jalur. Hasil menunjukkan bahwa kelompok eksperimen mengalami peningkatan signifikan, dengan N-Gain literasi (0.449) dan numerasi (0.439) lebih tinggi dibanding kelompok kontrol (0.268 dan 0.236). Selain itu, PK berpengaruh signifikan terhadap numerasi, tetapi tidak terhadap literasi. Penelitian ini merekomendasikan integrasi PBL dalam kurikulum untuk meningkatkan keterampilan siswa serta penelitian lanjutan terkait motivasi dan konteks sosial-budaya. PBL terbukti sebagai pendekatan inovatif yang relevan bagi peningkatan kualitas pendidikan di Indonesia. Abstract Literacy and numeracy skills are essential for individuals to reach their full potential, lead meaningful and productive lives, and participate fully in society. This study aims to examine the effectiveness of Problem-Based Learning (PBL) in enhancing the literacy and numeracy skills of primary school students in Medan, Indonesia. Employing a quasi-experimental design, the study involved 37 students in the experimental group (PBL) and 35 students in the control group (conventional learning). Data were collected through prior knowledge (PK) tests, as well as literacy and numeracy assessments, and analyzed using two-way ANOVA. The results revealed that the experimental group showed significantly greater improvement, with N-Gain scores for literacy (0.449) and numeracy (0.439) exceeding those of the control group (0.268 and 0.236, respectively). Additionally, prior knowledge had a significant effect on numeracy outcomes, but not on literacy. The study recommends integrating PBL into the curriculum to enhance student skills and encourages further research on motivational and sociocultural factors. PBL is demonstrated to be an innovative and relevant approach for improving the quality of education in Indonesia.
