To the Common page of both Ehmke Seminars (e.g. On-line material, Downloads ... )
 

In this seminar we shall learn how to produce interactive mathematical material containing visualizations/animations to be published on WWW pages. The tools are a Java applet called Geometria, originally programmed by David Joyce and further developed and extended by Dr. Ehmke, and the languages Html, Javascript and Java.  The most intresting feature in Geometria, when compared to e.g. Javasketchpad which we have used earlier, is an integrated response analysis system, which can be very helpful for the student, especially in distance learning.

Dr. Ehmke says in his abstract for the Klagenfurt 2001 ICTMT Conference: (With this contribution) I will introduce the Java-Applet Geometria, a tool for interactive worksheets to be presented on web-pages.  Worksheets generally contain a dynamic figure together with some kind of geometric learning content.  This content is described by means of a script-language (GeoScript) which provides the possibility to construct an euclidean figure and also supports the analytical definition of points, vectors and curves.  A special feature is the feedback given to the student, while he/she is interacting with the figure.  A tutoring component enables Geometria to evaluating and commenting on the student's answer.

Pre-work for participants The Seminar works on problem-driven basis, which means here that most activities will be targeted to solving problems posed by participants or the leader. Thus, the participants are asked to formulate or describe a situation, where an (interactively or automatically) animated picture could help the student to understand the mathematical meaning better than with a static picture or no picture at all.

Organization of the Seminar In the seminar there will be Common Activities (= lectures or exercises common to all participants) and Group Work hours. The computer lab M352 is reserved all week for the seminar.  Participants are devided to at least two working groups, depending on the nature of their problems and the tools they need to use/learn. One group will be those needing to learn some Javascript/Java, while others will need less of that, but will need more experiences in using the Geometria tool.
