| Summary: | 碩士 === 國立臺南大學 === 教育學系測驗統計碩博士班 === 107 === The 12year basic education adopts essential literacies as a piviot for curriculum design
and development.As an important subject, teachers should provide effecive learning pportunity to everyone in the math class, and help students to use tools such as ruler, compass, computer, calculator appropriately.To achieve the fundamental beliefs of the 12year basic education, teachers are professionals who must continue their professional development in order to support students’ learning.Thus, the use of technology in teaching and assessments is a core ability of teachers.In this research, a system named Geometric Construction Test(GCT) to evaluate the ability of geometric construction of 8th grade students is proposed.We hope this system can offer supplement to teachers and students.
The goal of this research is to develop a test of geometric construction using a software named Geogebra. Item difficulty parameters are estimated by classic testing theorem and Rasch model from the response of 903 students of 8th grade.To perform the GCT, we have 5 subtests: Copy a line segment, Perpendicular bisector, Copy an angle, Angle bisector, perpendicular from a line and 6 cognitive components: Dimension, Concept complexity, Solving steps, Steps in options, Proceedure/Application.And we provide item analysis by classic testing theorem, item response theorem, factor analysis. Multiple regression analysis is adopted for designing cognitive items.The proposed 5 components accounted 77.59% variances of difficulty parameters of GCT.
