This paper reports experiences in constructing web-based questions and assignments and delivering weekly exercises and formative tests in mathematics at upper secondary level in the Helsinki School of Natural Sciences.

During the WebALT project 2006-2007 and after it we have been constructing over 1000 algorithmic and interactive web-based questions for upper secondary level. The software we have used is MapleTA.

The new version of MapleTA has given possibilities to construct step-by-step questions and we have combined this feature also for constructing “find from the graph”-questions.

The assignments can be graded automatically. We can also ask questions where students write an essay as the answer. This type of questions cannot be graded automatically. Including “essay”-parts in questions the teacher is able to study the ways the students are thinking. At the end of an assignment one can also request feedback from the students and their self evaluation.

During spring 2009 we are going to test groups of last year high school students using WebALT assignments. We will study the correlation between students’ results for these tests and their results at the matriculation examination.

We also report about experiences of using these exercises in lower secondary school mathematics and at the schools for practical nurses in drug calculation.
