Pocket Book Design Based On Mathematical Puzzles To Improve The Mathematical Logical Intelligence Of Grade XI Students

Teachers have a big role in developing and improving students' mathematical logical intelligence skills. However, teachers only focus on using package books teaching the classroom. As result, students do not show great attitude of enthusiasm, struggle are unable to think logically, creatively innovatively skills when doing math problems. Therefore, researchers interested creating pocket book based Mathematical Puzzles (TTM) class XI. This study aims determine feasibility, practicality effectiveness pocketbook. research is development or R&D with 4-D 3-D model. The results this calculation value V Aiken validation data material experts 0.903 media 0.8 classified as feasible use. Then student response 0.932 teacher 0.894 very practical use during learning. While t-Paired test pretest posttest obtained ,t-count.=6.1807, there an increase so that categorized effective. It can be concluded pocketbook XI puzzles improve ability students.
