Abstract
This study aimed to develop manipulative learning media based on STEM (Science, Technology, Engineering, and Mathematics) called Magic Hours on Clock and Corner material. Research and development model used by using the procedure of Analysis, Design, Development, Implementation, and Evaluation (ADDIE). The population of this study was all 4th grade students from elementary school in Kediri. Due to the Covid-19 Pandemic situation and study from home policy, manipulative media was tested on 13 fourth grade elementary school students in Kediri who came from the same village to reduce students' mobility from one place to another. Data collection techniques are collecting through expert validation, teacher questionnaires, student questionnaires, test, observation, and interviews. The instruments are test (description questions) and non-test instruments (material validation sheets, design validation sheets, practicality assessment sheets, questionnaire validation sheet, and questionnaires). The result shows that the learning media are valid, practical, and effective. Learning media have feasible criteria with an assessment score of 88.46% from media experts and 86.67% from material experts. In the practicality test, learning media obtained a percentage of 86.67% with practical criteria. The result of a one-sample t-test on student test scores indicates that the average mathematics score test is significantly more than Minimum Completeness Criteria.
Highlights
Mathematics is one component that has a significant role in the world of education
In order to reduce student mobility from one place to another during the Covid-19 Pandemic situation, manipulative media called Magic Hours was tested on 13 fourth grade elementary school students from several elementary schools in Kediri who came from the same village
The necessity was students like activities that combine knowledge and skills to reduce conventional learning model, students like different learning activities one of which is by using learning media that can show the interrelation between subjects studied so the solution made a manipulative learning media based on STEM that can be held and operated independently by students and allows students to learn several subjects at one time
Summary
Mathematics is one component that has a significant role in the world of education. In Indonesia, mathematics is taught at the educational’s level start from kindergarten to college. According to Mahmudah, Ahyan, & Rasidi (2018), mathematics needs to be learned because mathematics means solving problems in everyday life, thinking logically, clearly, critically, and acts a basics science to study others. Several problems occur in learning mathematics, including the lack of maximum use of media in the learning process and the complexity of the material delivered by the teacher who impacts poor understanding of students. Innovative solutions are needed by teachers so that initially complicated learning mathematics becomes easy and can reduce fear or laziness in learning with students. One alternative solution that teachers can apply is the use of interested and varied learning media
