Abstract

This study aims to analyze the order of textbooks based on van Hiele's theory. The research approach used is descriptive qualitative. The method used is content analysis or content study. The data subject in this research is junior high school mathematics textbook grade VIII curriculum 2013. The research was conducted by looking at the suitability of the characteristics at each van Hiele level with the textbook. Then if a discrepancy is found in the analysis, a solution is given according tZo the researcher's skills. The results showed that in general all the material "Surface Area of Cuboid and Cubes" in the Mathematics textbook of junior high school grade VIII curriculum 2013 material on the concept of surface area of cuboid and cubes has not fulfilled the order based on van Hiele's theory as a whole, namely there is an incomplete explanation in each level. The level of sequence analyzed in this textbook reaches level 2 (Ordering). So it is recommended for future research that the results of this analysis be used as a reference in teaching geometry material to students.

Abstract

This study aims to create media products that are suitable for use and make it easier for students to understand the material concept of the relationship between coefficients and discriminants of quadratic functions with their graphs. The media was developed using GeoGebra and student worksheets. This study uses the development of the ADDIE model with the stages of analysis, design, development, implementation, evaluation. The developed media was tested on 29 students of SMP Salahuddin class IX D. The developed media was declared valid based on the validator's assessment with the percentage of validity of interview guidelines 97%, learning media 92%, student worksheets 94%, lesson plans 94%, quizzes 91%, 95% student response questionnaire, 93% student activity observation sheet, 92% teacher activity observation sheet. The media is declared practical based on the teacher's assessment with the percentage of practicality of student response questionnaires 88%, student activity observation sheets 96%, teacher activity observation sheets 96%. The media was also declared effective based on student quiz assessments with a percentage of 93% of students getting an average score of at least 80 completeness requirements the graph.
