KOMPARASI PEMAHAMAN KONSEP DAN GENERALISASI MATEMATIKA ANTARA STUDENT RESEARCH DAN DIRECT INSTRUCTION BERBANTUAN CABRI 3D
Abstract: Geometry of space
becomes a more difficult course compared with the basic geometry. Considerable
evidence indicates the level of difficulty. In the geometry of space, students
still have to transform three-dimensional objects into two-dimensional image field.
This is related to spatial ability students. By combining the usefulness of
mathematics and the development of science and technology it developed a
mathematical model of teaching based on computer technology. The use of Cabri
3D in teaching space geometry was meant for the students to make educated
guesses / conjectures, test conjectures, construct and make generalizations
generally. The hope with the help of computers, the constraints and
difficulties that exist can be eliminated little by little. The problems are
going to be resolved through this study were 1). Are there differences in the
ability of understanding the concept of school geometry student research
through teaching strategies and direct instruction assisted Cabri 3D? 2). Are
there differences in the ability of generalization through teaching strategies
and direct student research Cabri 3D-aided instruction? The subject of this
study is the fourth semester students of the school year 2010/2011 State
University majoring in mathematics negei Semarang. The results showed 1). There
were no differences in the ability of understanding the concept of school
geometry student research through teaching strategies and direct instruction
assisted Cabri 3D. 2). There are differences in the ability of generalization
through teaching strategies student-assisted research and direct instruction
Cabri 3D.
Keywords: understanding of
