Tour description

The introduction to cell growth module is an adaptive module. Adaptive means that it will adapt to the level of the user. The module is used to give students with heterogeneous backgrounds an introduction to growth. Some students can finish this module in 2 hours, others need 6 hours to finish the module, it depends on their prerequisite knowledge and experience. In the end all students will have the same level.

The module starts with the description. There are two introduction movies, showing a small lecture that introduces all aspects of cell growth modelling.

  • Click Intro cell growth in batch. A new window will open with a introduction lecture. Close the window when finished.

The important part of the module are the Questions. Because the module selects the most appropriate question, this tour cannot predict which question is presented.

  • Click Questions. You can now select between easy, medium or difficult questions.

Students have choice what question they get. If the student chooses Easy, the student will get many questions. If the student chooses Difficult, the student will get only few questions.

  • Choose a question.

This is what the questions look like. On the top you can see this question can give you points, and how many points you need in total. Easy questions give generally few points, hard questions give more points. Whether or not a question is considered easy or difficult depends on the questions the student has answered so far (and the results of those answers).

On the right side students can switch to another question if this question is too easy or too difficult. However, at some point, this question (or an equivalent) will return and they will have to answer it.

You can now try some questions. If you answer them right you can win many points, if you need many tries to answer them you can win only few points. There are more then 100 questions in the database.

Choose questions and try to answer them. Watch the points.
