Abstract

The low level of numeracy literacy in Indonesia is due to the material tested on TIMSS and PISA, which consists of questions in real-life context problems. Students are not accustomed to solving real problems and cannot analyze information in various forms. The lack of engaging learning materials contributes to students' boredom and makes it difficult for them to tackle numeracy and literacy challenges. This study investigates how well students can read and compute after using the iSpring 11 learning resources. Twenty students from class VII at State Junior High School 46 Palembang were the research subjects. The research method used is design research with a development study, which at the prototype stage uses the Tessmer model. The focus of discussion in this research is the results of the field test stage, where data collection techniques include tests and interviews. Data analysis techniques include test data analysis and interview analysis. This research demonstrates that students' numeracy literacy skills are excellent, with an average score of 88 after learning using the iSpring 11 learning media.

Media pembelajaran berbasis teknologi dapat membantu pendidik untuk menyampaikan konsep dari materi pecahan kepada peserta didik. Jenis dari penelitian ini adalah Research and Development yang dikembangkan berdasarkan Tessmer. Metode penelitian ini terdiri dari tahap Preliminary (persiapan dan pendesainan) dan tahap prototyping (validasi, evaluasi dan revisi). Pengumpulan data dilakukan dengan menggunakan lembar validasi dan wawancara. Data validitas diperoleh dari komentar dan saran validator. Data kevalidan diperoleh pada tahap expert review. Media pembelajaran yang dikembangkan oleh peneliti divalidasi oleh 3 ahli yaitu ahli media, ahli soal dan ahli materi. Tujuan analisis data tahap expert review yaitu untuk memudahkan keputusan dalam merevisi media pembelajaran. Hasil penelitian menunjukkan bahwa media pembelajaran dikatakan valid secara kuantitatif dan kualitatif dengan persentase 85,6%. Kata kunci: Media Pembelajaran, Perkalian Dua Pecahan, Literasi Numerasi.

Abstract

This study explores a learning trajectory to teach three-dimensional positioning using augmented reality (AR) and assesses students' numeracy literacy skills after using AR-based learning. The research follows a three-stage design research approach: preparation, the design experiment (split into pilot and teaching phases), and retrospective analysis. The study incorporates three AR-based activities in a student worksheet. In the first activity, students observe the AR simulation of a futsal field to identify spatial elements. In the second, they interact with the AR to determine positions in three-dimensional space. In the third, students solve related spatial problems, applying their numeracy skills. The AR-based design aims to enhance students' understanding of three-dimensional positioning for Grade XII high school students and assess improvements in their numeracy literacy through these interactive, structured activities.

Abstract

This study aims to determine the validity and practicality of student worksheets with the help of Artificial Intelligence (AI) to strengthen numeracy skills in algebraic operation material. This type of research is preliminary and formative evaluation stage research. At the preliminary stage, product preparation and design have been carried out. Furthermore, the formative evaluation stage involves expert review, one-to-one, small group, and field test stages. The material used was data presentation, questions based on numeracy literacy, and some related to numeracy literacy indicators. The data collection techniques used were questionnaires and interviews. Questionnaires consisting of validity and practicality questionnaires. Validity data was obtained from comments and suggestions from experts. Practicality data were obtained through questionnaires and interviews that were analyzed qualitatively. The potential effect can be seen from the calculation of the evaluation results. The research subjects used were grade VII students at SMP Negeri 31 Palembang. The results showed that student worksheets with the help of AI were declared valid at the expert review stage and declared practical from the results of practical questionnaires and interviews in the one-to-one, small group.

Abstract

Artificial Intelligence has significant potential to enhance the mathematics learning experience. To fully realize the benefits of AI integration, it is crucial to develop teaching materials that effectively incorporate AI into classroom instruction. This study focuses on developing AI-based student worksheets to improve numeracy literacy skills among junior high school students. These worksheets were created with the support of AI technology and include AI applications that can be used directly during the learning process. Conducted in state junior high schools (SMP) and Islamic junior high schools (MTs) in Palembang, the project followed a series of formative evaluation stages. These stages involved self-evaluation, expert reviews, one-on-one sessions, small group testing, and field testing, alongside product dissemination activities. Data on students' numeracy literacy skills were gathered through interviews and tests, while the analysis process consisted of three key stages: data reduction, data presentation, and drawing conclusions. The findings showed that some students had already grasped the steps to solve problems. Overall, the evaluation results for the numeracy literacy test were categorized as high performance. The AI-based worksheets proved effective in helping teachers deliver engaging teaching materials and enhancing students' learning experiences, particularly in improving their numeracy literacy.
