Wong, Wing-Kwong; Yin, Sheng-Kai; Yang, Chang-Zhe – International Review of Research in Open and Distance Learning, 2012
This paper presents a tool for drawing dynamic geometric figures by understanding the texts of geometry problems. With the tool, teachers and students can construct dynamic geometric figures on a web page by inputting a geometry problem in natural language. First we need to build the knowledge base for understanding geometry problems. With the…
