The film "Beyond the Microscope" is also used to demonstrate the students how the gases are formed in the tube or how many hydrogen and oxygen be obtained form water by electrolysis. The film shows the attraction of hydrogen ions to the cathode. The film "Water Cycle" provides information ...
The teacher informs the students that the test value represents the content of dissolved calcium ions (water hardness). He/she reveals that these are different drinking water samples (from the urban area of Salzburg) and names the places where the samples were taken from. The discussion will co...
To close this gap, we conducted the current study to examine how mathematics teachers' beliefs about their roles shape the ways in which they interact with their stu- dents. The following research questions are addressed: (1) What beliefs do mathemat- ics teachers report about their roles in...
The prediction errors are evaluated on the Ions-12 (up to 12 non-H atoms) data set which provides a measure of the performance of the model with respect to the data points similar to those used for training. On the other hand, errors on Ions-16 (13–16 non-H atoms) can be seen a...

If you really know about it, ideally you should be able to give a short talk without notes explaining a) how it works and b) what the main advantages and disadvantages are and why it is controversial. You’d be able to compare it to other energy sources in terms of human and ...
Most of these references emerge natural- ly in the course of frequent conver- sations during the year. A number of strategic research sites and key events are particular- ly illuminating for our understand- ing of how knowledge grows in teaching. Often a young teacher will be expected to ...
interacts with other learners or the teacher, concepts are formed in a natural way because through talking to each other, they have collectively created a world that can be described and discussed as well as a common framework under which communication takes place (Solomon, 1987). The case-base...
That means that a salt can be formed from any two ions. Below are the electron-shell diagrams of magnesium (Mg) and chlorine (Cl).xvi. If table salt (the kind you eat) is sodium chloride (NaCl), what is the molecular formula of magnesium chloride? a) MgCl b) Mg2Cl c) MgCl ...
As another example, mathematics instructors lacking knowledge of how stu- dents are likely to be thinking about a topic may strug- gle to consider whether an example, counterexample, or explanation they intend to provide will be understand- able to students (Johnson & Larsen, 2012). Instructors...
