Abstract:
Quoting the Nobel Prize winner F. Jacob: “there are many generalizations in biology, but precious few theories. Among these, the theory of evolution is by far the most important ... ; it unites all the disciplines concerned with living beings, …; in short, it provides a causal explanation of the living world and its heterogeneity”. Thus, the very nature of evolutionary biology might explain why the result of the teaching of evolutionary theories is not generally positive [1, 2]. However the tendency is to continue teaching as we were taught. The traditional teaching style is focused on the instructor and solely the teacher determines what is to be taught. Furthermore, many evolutionary concepts are often just taught but rarely learned. On the other hand, the rise of Google and Wikipedia has changed the teaching techniques but favors the copy-paste culture and a false sense of wisdom. Here a hybrid system; which comprises traditional lectures, virtual learning, computer simulations and cooperative learning techniques, is devised for undergraduate students. The main goals of this system are: 1) set the foundation of critical thinking required to discuss evolutionary theories, 2) reinforce the “elusive” abstract thinking, and 3) provide flexibility for responding to student’s schedules and interests. Briefly, the proposed distribution of resources is as follows:
1) Lectures on microevolutionary mechanisms and Hardy-Weinberg theory. Although rather abstract, and therefore difficult to comprehend by the students, these concepts constitute the core of the evolutionary thinking and somewhat the starting point before the students can learn autonomously.
2) Virtual resources, which include a wiki and a forum, intended to provide flexibility to the topics chosen. The students must choose the topic from a list but they can also provide new topics. Besides the lecture slides are uploaded to the platform but not the lectures notes so that the students are assigned to write cooperatively a manual.
3) Computer-assisted Problem Based Learning: students are encouraged to make answers rather than just find them.
4) Computer-assisted Case Based Learning: to stimulate significant learning, computer simulations are used to establish and test alternative hypothesis.
