Abstract

The van Hiele theory offers learning phases as an effective way to be applied in geometry classes. Because there is the difference of students’ ability in solving circle geometry problems, a module can be used to deal with. This article describes the developing process and validating of circle module based on van Hiele theory. The developing model was Plomp model. The module was developed by five phases of van Hiele theory, namely inquiry, guided orientation, explicitation, free orientation, and integration. In addition, this circle module was developed in seven sections, those were elements and parts of the circle; the value of Pi and the perimeter of circle; the area of circle; the central angle and the inscribed angle; arc length, area of sector and area of segment; the properties of tangents; and the direct common tangent of two circles and the indirect common tangent of two circles. Based on the result of validation from expert, field trial in the class, and the legibility tryout of the module, the circle module based on van Hiele theory was declared valid to be used as learning resources.
