Developing Mathematics Learning Media Based on Macromedia Flash by Using Problem-Based Learning to Improve Students’ Mathematical Spatial Ability Jihan Hidayah Putri, Edi Syahputra, Mulyono American Journal of Educational Research. 2019 7 (10). doi: 10.12691/education-7-10-6 Keywords: macromedia flash, problem based learning, spatial ability Context: This research was aimed to know the validity, effectiveness and practicality of Macromedia Flash development in learning media so that it can improve the students’ spatial ability. This research subject was eighth grade students of SMP Negeri 1 Batang Kuis 2019/2020. This research object was Macromedia Flash application in Mathematic subject of solid geometry (cube and cuboids) using Problem-Based Learning. This research instrument was testing the spatial ability. This is a development research which used 4-D development model. The result of this research is valid known from the learning media validity score with the average of 4.55 from the media expert and 4.64 from learning material expert, then the validity score total of lesson plan is 4.48; worksheet is 4.62; the spatial ability test and Mathematic learning motivation survey are also valid. The mathematic learning media which was developed is effective, known from students’ learning mastery calcically reached 91.99%. The improving of students’ spatial ability used learning media which was developed on solid geometry subject (cube and cuboids), shows the increasing in average score from 67.93 to 84.13 .The average score of each spatial ability indicator is also increasing.

Development of Mathematics Learning Tools Based Van Hiele Model to Improving Spatial Ability and Self-Concept Student's of MTs.S Ulumuddin Zulfahmi, Edi Syahputra, Kms. M. Amin Fauzi American Journal of Educational Research. 2017 5 (10). doi: 10.12691/education-5-10-9 Keywords: learning tools development, Van Hiele model, spatial ability, self-concept Context: This research aims to describe: (1) product validity of learning device development based on Van Hiele model, (2) the practicality of product development of learning device based on Van Hiele model, (3) the effectiveness of product development of learning device based on Van Hiele model, (4) improvement of students' spatial skills by using the tools that have been developed based on Van Hiele model, (5) increase the ability of self-concept students by using the device that has been developed based on Van Hiele model. The research was a development research. The development model was used 4-D model consisting of four stages, namely: Defining, designing, developing and distributing. The study to test trials was conducted on the class VIII of MTsS Ulumuddin. Test trials 1 conducted on the class VIII-2 and test trials 2 was conducted on the class VIII-3. Based on the results of the development it¡¯s showed that: (1) The valid learning tools developed with the total average validity of RPP¡¯s score was 4.50, Student Book¡¯s score was 4.30, Master Book¡¯s score was 4.30, and LAS¡¯s score was 4.40; (2) The practical learning tools developed showed based on students¡¯ activities within the prescribed tolerance limits; (3) The effective learning tools developed can be seen based on from the students' learning completeness in the classic, and achievement of learning objectives of at least 80% (4) The average achievement of students' spatial ability in the trial I was 3.15 increased to 3.51 in trial II; and (5) The average achievement of students' self-concept trial I was 3.03 increased to 3.16 on trial II.

The Influence of Project-based Learning Strategy and Self-regulated Learning on Academic Procrastination of Junior High School Students’ Mathematics Learning Dahlia Novarianing Asri, Punaji Setyosari, Imanuel Hitipeuw, Tutut Chusniyah American Journal of Educational Research. 2017 5 (1). doi: 10.12691/education-5-1-14 Keywords: project-based learning strategies, self-regulated learning, conventional learning strategy, academic procrastination, learning mathematics Context: The objective of this study is to obtain conclusions concerning different levels of junior high school students’ academic procrastination in learning mathematics by applying a project-based learning strategy and a conventional learning strategy. The different levels of junior high school students’ academic procrastination depend on high or low self-regulated learning and the interaction effects of project-based learning strategies and self-regulated learning in accordance with academic procrastination of junior high school students in learning mathematics. Experimental research design was used in this quasi-experimental research, along with its cluster random sampling technique. The data collection instrument was self-regulated learning and academic procrastination scales. The data analysis techniques to test hypotheses was a two-way Anava track. The result shows (1) differences in the levels of academic procrastination in learning mathematics for junior high school students who got the project-based learning strategy and conventional learning strategy, (2) differences in the levels of academic procrastination for junior high school students who had low self-regulated learning, and (3) an interaction effect of project-based learning and self-regulated learning strategies on academic procrastination of junior high school students in learning mathematics.
