1. Towards an integrated learning environment for mathematics Christian Bokhove (St. Michaël College, Zaandam, secondary school) Gerard Koolstra (St. Michaël College, Zaandam, secondary school) Peter Boon (Freudenthal Institute, University of Utrecht) André Heck (Amstel Institute, University of Amsterdam)

2. 2 The GALOIS project geïntegreerde algebraïsche leeromgeving in school [integrated algebraic learning environment in school] developing a framework at secondary school for pupils who do mathematics to: - assess their own progress, anytime anyplace - have access to a large amount of randomized exercise material (CAS-based tests, applets, ….) - get functional feedback on their work - store their activities and answers (+ the route to the answers) in a Virtual Learning Environment (VLE) Major constraint: open source software and open standardsapplets Participants: one secondary school and two universities

3. 3 1st phase: state of the art Existing software  Applets form the Freudenthal Institute  Wiris (www.wiris.com)www.wiris.com  Activemath (www.activemath.org)www.activemath.org  STACK (www.stack.bham.ac.uk, initially with RQP)www.stack.bham.ac.uk  More… Best suited?

4. 4 2nd phase: development A cyclic process (since 2000) of:  brainstorm  programming  development of additional materials  try-out  revision of the applet  try-out  …. Two kinds of try-out  Do the applet and materials “work” (technical)?  Do they work in “real” situations (e.g., in the classroom)?

6. 6 1. Design of Applets for Learning Math What is an applet? A small computer program that runs over the internet. - on a server - only one version (the latest version) What is a WisWeb applet from the Freudenthal Institute? An applet - embedded in a didactical concept - that is dynamic, interactive, and with friendly interface - with not just a users’ guide, but also with background information, and (written) instructional materials - for different uses (closed/open) in school practice:  applying knowledge,  concept construction,  supportive tool,  practice basic skills,  assessment,… 1

9. 9 The Digital Math Environment is a web-based application in which a student  works with an applet on a central server  automatically receives (intelligent) feedback  stores works and in which a teacher can  monitor progress of  individual students  the entire class  But because we use SCORM other VLE’s can be used 2

15. 15 5. SCORM-compliant Applet Generator Disadvantages of the Digital Math Environment: Missing communication facilities like email, bulletin board; Yet another environment to learn in addition to VLE with which students and teachers are familiar; Administration outside own school. Requirements for integration of applets and existing VLEs Applets and VLE must be able to communicate; Sharing of content in various VLEs should be possible; Mechanism should be extensible for other applets or computer programs; Compliance with existing standards. Chosen approach: Sharable Content Object Reference Model (SCORM) for WisWeb applets and Javascript-based DITwis tests. 5

16. 16 Example: Authoring questions (derivatives) 5

17. 17 Example: Addition of two fractions 5

18. 18 Example: Authoring questions (addition of fractions) marking scheme levels and number of questions random parameters correct answer question text with a formula intermediate steps operations disabled title 5

19. 19 Only programming aspect for teacher is the use of hash signs in formula generation and in the specification of the correct answer example with parameter values: a = 4, b = 7, n = 12 the choice of marking based on  equivalence  rewriting in particular form  exact shape of correct answer formulaexplanationsample #a# / #n# + #b# / #n# formula ‘as it is’ 4/12 + 6/12 #a / n# + #b / n# simplification, but no addition 1/3 + 1/2 #a / n + b / n# full arithmetic of fraction 5/6 5

20. 20 3rd phase: classroom experiences Add-on value of applets is that they are attractive and motivating in the eyes of the students (especially they like the game-like behavior); stimulate students' creativity (open applets) and help them gain more self-confidence (closed applets, exercise applets); get "natural feedback" to students (not just right/wrong); can become a frame of reference for students; are flexible and simple to use; they can also be used at home;

21. 21 offer the opportunity for teachers to positively address individual differences between students; provide a change of instructional format and are an alternative to the "boring" textbook; help to create a useful computer learning environment; allow a versatile approach to algebra and calculus.
