Abstract

Critical thinking is needed in problem solving. To solve problems, students will use a variety of strategies. Critical thinking ability play a role in determining the strategy used, which is also influenced by students' cognitive styles. In this research, the cognitive style discussed is reflective cognitive style. This research is a qualitative with a case study approach. This research aims to describe the critical thinking ability of students in solving algebraic numeracy problems based on reflective cognitive style. This research was conducted in Class VIII Junior High School students. The research subjects were selected through MFFT (Matching Familiar Figure Test) and Mathematical Ability Test. Data analysis techniques include data reduction, data display, and conclusions. The selected research subjects from reflective took the critical thinking ability test and interviews. The results of the critical thinking test and interviews were analyzed to describe the critical thinking in solving algebraic numeracy problems. The results showed that reflective cognitive style student fulfill each criteria of critical thinking ability FRISCO (Focus, Reason, Inference, Situation, Clarity and Overview). The reflective student is able to carry out the focus and reason criteria of critical thinking ability by identifying the main points of the problem and providing reasons for the relationship between what is known and asked correctly and completely. Reflective student is able to carry out the inference and situation criteria by deciding on the right strategy and solving the problems given correctly and systematically. Reflective student can also able to carry out the clarity and overview criteria of critical thinking ability by drawing conclusions and re-examining the solution of the problems given. So, reflective cognitive style student is categorized as very critical. It is suggested that teachers provide more practice questions and provide further discussion with limited working time.

Abstract

Mathematics learning videos are audio visual media that make lessons more engaging by aligning with students’ audio-visual learning styles and illustrating real-life applications through digital storytelling. However, numeracy performance remains low—only 19% (4 of 21 students) mastered topics like mean, median, mode, and range. Efforts to address this problem are to use mathematics learning videos based on digital storytelling to strengthen students’ numeracy. This study aims to describe the content validity making such a video for strengthening students’ numeracy skills. In this research used the ADDIE development model, which focuses on three stages: Analyze, Design, and Develop with evaluations at each stage. However, this article focuses on the validation assessment of mathematics learning videos based on digital storytelling. The instruments used consist of a material expert validation instrument and a learning video validation instrument. The media was validated by three experts in the field of learning media, visual programming, and digital storytelling. The data analysis technique uses the Aiken V formula. Based on this, the results of the validation analysis are shown by obtaining a score of 0.854 from video experts (highest in usefulness) and 0.83 from material experts (highest in learning objectives) both were categorized as valid. The assessment by experts shows that the mathematics learning video is suitable for use with revisions. Several revisions were made to mathematics learning video based on digital storytelling to make it more interesting. Further research is recommended to develop the mathematics learning video into an application that can be used offline and allows for automatic answer storage settings.

Abstract

The low percentage of numeracy proficiency among junior high school students, as reported in the 2024 Indonesian Education Report, emphasizes the importance of high-quality numeracy questions equivalent to the Minimum Competency Assessment as effective practice materials to enhance students' numeracy skills. This study aims to analyze the characteristics of numeracy questions equivalent to the Minimum Competency Assessment delivered through the Jotform platform for junior high school students. The items are developed as online practice materials aimed at familiarizing students with solving numeracy problems in accordance with the standards of the national competency assessment. This research is an exploratory study using a quantitative approach. The primary data were collected from the result of 20 numeracy items distributed through Jotform to 27 students enrolled in the eighth grade of a privacy secondary school located in Surabaya. Four analyses were conducted to examine the item characteristics: validity, reliability, difficulty index, and discrimination index. Findings indicate that the average validity of the items falls within the moderate level, the reliability in categorized as high, the average difficulty index is also in the moderate range-suggesting the items are effective for evaluating students’ numeracy skill-and the average discrimination index demonstrates an excellent classification. In light of the results, the questions are considered appropriate for use in online numeracy practice.
