This task has been developed by the chemistry teacher Andrea Heiseler and has been successfully applied in a school class in Cologne (age group 16-17 years). The students followed the instructions of a WEB-Quest and developed a "folder" on the sulphur cycle in parallel to normal classes over a time span of about 4 weeks with one (of three) lessons per week supported by the teacher.
Model of teaching (3 lessons of chemistry per week):
|
Time frame: |
4 weeks |
|
Topics of regular classes (2 of 3 lessons per week) |
the element sulphur, sulphur production, sulphur acids, concept of acids and bases, pH-value, acid rain |
|
WEB-Quest support
(1 of 3 lessons per week) |
Problems and questions (technical approaches, structuring, content related questions) concerning the WEB-Quest are discussed |
|
Self-contained learning of the students (homework, individual work on school computers) |
The WEB-Quest is handed over to the students and its tasks are fulfilled in individual work by the students. The result is summarised in a "folder" which is evaluated by the teacher after the four weeks. |
The WEB-Quest is offered as a downloadable and online version: Please CLICK HERE!
The online version is helpful for the students since it contains the active links to the material.
