KEMAMPUAN BERPIKIR KRITIS MELALUI PEMBELAJARAN MATEMATIKA DENGAN PROBLEM BASED LEARNING

Education functions to upgrading, forming, character and develop civilization nation. Having the ability to think and actions to effective and creative in the realm of abstract and concrete can be used as self development independently. Students need to armed with critical thinking skills, systematic, logical, creative, and cooperate effectively to obtain, choose, and manage an information. Mathematics learning is directed to develop critical thinking skills and discussed open and objective because mathematics having strong and structure clear and links between the concept of the one with another concept. By analyzing learning needs of mathematics, formulate and designed a learning programs, choose a strategies and evaliated them correctly to get good results. The ability critical thinking is very important in studying new matter and that known way, and learn to ask effectively and reach a conclusion consistent with the facts. Mathematic learning with problem based learning is the concept of better used activity of the student during learning. In accordance with statements from Westwood (2008: 31) stated that PBL: 1) propel oneself directly in learning, 2) prepared students to critical thinking and analytical, 3) give opportunity to students to identify, find and use numerous this approuch in should think, 4) is the learning is very closely related to the real world and motivate students, 5) involving activeness in integrating information and skills of various the discipline, and 6) knowledge and strategy by the possibility of will be maintained and tranferred to the learning situation other, improve the ability to communicate and the social skills needed to cooperation and teamwork. By chance the learning process as an alternative in solving mathematical problems with using the ability critical think an to cultivate the scientific attitude of student.

PEMBELAJARAN IPA BERBASIS MULTIMEDIA INTERAKTIF UNTUK MENINGKATKAN MINAT DAN PRESTASI BELAJAR SISWA

This paper aims to study science learning using interactive multimedia based on the level of interest in students learning. The learning interest is one of the determining factors of student learning outcomes. The students who have high learning interest in a lesson will have better outcomes than the students who have low learning interest. The ability of a teacher to help improve student learning interest is needed to improve student learning achievement. Selection of the right learning media is one of the way to help students improve their learning interest in a lesson. Interesting and interactive learning media will make students interested in using the media, so that the students' interest in learning will be indirectly more increased than before using the learning media. Interactive learning media can make students to do various movements such as eye movements in observing something that is on the learning media and also the brain movements for thinking, thus the students will be able to stay focus on the material that is being studied. The media that is capable of carrying out these functions which are then referred to as interactive multimedia.
