  2. OPTEK • OPTEK was a TEKES-funded large-scale multidisciplinary research endevour • The goal of the project is to create innovative solutions and models for using ICT and digital media in schools • OPTEK is a joint initiative of 13 research units carried out in collaboration with 28 enterprises and schools in 12 municipalities. • We participate in the project with a part involving mathematics education

  3. OPTEK(2) Project objectives The general goal of the ÅA/UTU part of the project was to study and develop the use of computer based support for teaching and learning mathematics at junior high (grades 7-9) using open source software. What was studied • Students' ability and desire to read and write mathematics on the computer with customized software. • The feasibility of using open source software in mathematics education.

  4. What was done • Computer-based learning material is built using the open source learning management system Moodle • Interactivity is an important aspect of all parts of the material, which includes theory, examples, exercises and assignments • Students solve assignments by writing their solutions as structured derivations using the open source text editor LyX • LyX-editor provides good support for writing mathematical text • All examples are also presented as structured derivations

  5. Showing mathematical text in electronical environment Other subjects Mathematics

  6. Writing mathematics with computer <math xmlns="http://www.w3.org/1998/Math/MathML"> <mi>x</mi> <mo>=</mo> <mstyle displaystyle="true"> <mfrac> <mrow> <mo>&#x2212;<!-- − --></mo> <mi>b</mi> <mo>&#x00B1;<!-- ± --></mo> <msqrt> <msup> <mi>b</mi> <mn>2</mn> </msup> <mo>&#x2212;<!-- − --></mo> <mn>4</mn> <mi>a</mi> <mi>c</mi> </msqrt> </mrow> <mrow> <mn>2</mn> <mi>a</mi> </mrow> </mfrac> </mstyle> </math> $x=\dfrac{-b \pm \sqrt{b^2 -4ac}}{2a}$

  7. Structured derivations • All material was written with structured derivations • Student wrote some exercises in format of structured derivation

  8. LyX • LyX is an open source text editor, witch provides exelent suport for writing mathematical text • Suport for writing structured derivations was added

  9. Structured derivation with LyX

  10. Moodle • Moodle is open source learning management system • All material (theory, examples, exercises and assignments) was available to student via Moodle • Students saved all LyX-made assignments to Moodle

  11. Basic idea

  12. Experiment in Puropelto • System was used as additional material • The experiment showed that students have ability and will to use computers as a part of mathematics studies • Results inspired us to make a fully electronic course for 7th grade

  13. Experiment in Punkalaidun • Whole course was taught with electronic material and everything was done only with computers • System had not negative effect on students grades, even the system was new to both teacher and students • Students learnt easily to use the system and most of them liked it

  14. Examples from course • Theory

  15. Examples from course • Example

  16. Examples from course • Moodle exercices

  17. Examples from course • Interactive exercises (Moodle)

  18. Examples from course • LyX assigments
