3 Methodology
In their first semester teacher trainees take part in a practical course learning
basic laboratory skills such as handling a gas torch, weighing solids, setting up
solutions and developing analytical reactions. In preparation for the main
course students learn to document laboratory activities not only using paper
and pencil but also tablets.
In their second semester the main practical course leads teacher trainees to
planning, conducting and reflecting on inquiry-based experiments. A 2x2
matrix ensues three experimental and one control group (EG1=control group,
EG2-4= experimental group as shown in Figure 2). All groups carry out
investigations using experimental instructions, which are modified and adapted
to inquiry-based learning (advanced inquiry and explanation support). Teacher
trainees work collaboratively in teams of four in each experimental or control
group. Therefore each team member takes on a special task such as
experimenting or documenting the investigation.

3.1 Treatment
The implementation of self-regulation and tablet support in the inquiry process
promotes a blended learning environment using e-learning support and faceto-face
meetings in the practical course. Practical courses are converted from
a face-to-face-only setting to a blended-learning environment by using e-
learning support (Figure 3): teacher trainees prepare at home for a given
inquiry question online (e-learning platform) by working on the materials and
then doing an online test. They meet in their teams at university to plan and
conduct their investigations. The inquiry process is documented by a video
journal (similar to a paper-pencil journal) produced with tablets. At the end all
teams reflect on their investigation by presenting and discussing their video
journals with their peers in a plenary session. Back at home, the video journals
are uploaded to the e-learning platform. Peers and tutor give feedback on the
journals online, having flexible access to it.
