Abstract
One of the most important subject to improve cognitive and students skill is Mathematic. Considered as human activity, Mathematic is also a subject which highly demands logical, rational, critical, and systematical thinking. Mathematical cognitive which of course enables to provide helpful aids to the students to deal with the problems in their daily life. As an effort to improve the learning quality in the classroom, an effective and proper learning model is required to be considered by a teacher. Thus, it is expected to develop students engagement and cognitive skills. A learning model issued in this investigation is Problem Based Learning. This investigation is aimed to (1) to measure Mathematical cognitive skill and students engagement toward curved-face three-dimensional objects in IX grade of SMP Laboratorium Percontohan UPI using problem based learning model. (2) to find out the improvement process of Mathematical cognitive skills and students engagement toward the chapter of curved-face three-dimensional objects during the implementation of problem based learning model in IX grade of SMP Laboratorium Percontohan UPI. (3) to improve Mathematical cognitive skill and students engagement toward curved-face three-dimensional objects in IX grade of SMP Laboratorium Percontohan UPI using problem based learning model. The result of this investigation shows that the Mathematical cognitive skill and students engagement can be improved through the implementation of the problem based learning model toward the chapter of curved-face three-dimensional objects. The Learning shows a significant result from cycle I to cycle III and keep improving from cycle to cycle. The average score appeared in cycle I is 69.9, this score keep gaining a significant improvement of 81.7 in cycle II and becoming more significant as 85.8 in cycle III. In addition to the result above, this PBL model is able to improve the students engagement and accomplishment from cycle to cycle. Starting from the 1st cycle, the students accomplishment reach 34.37%, 2nd cycle reach 75%, meanwhile the 3rd cycle the students accomplishment reach 90.625%. From the short elaboration above, the investigator jumps to a conclusion that Problem Based Learning Model can improve students Mathematical Cognitive Skills and Engagement. Therefore, the Problem Based Learning Model is extremely recommended by the investigator to be implemented towards other material or chapter and used as an alternative Mathematic learning model at school.
