36 APPENDICES TO CHAPTER 13 xxxvii Structured Interview Construction of molecular models and writing of stereo-chemical formulas This group of twelve questions is dealing with the construction of molecular models using the computer program echem 1, manual construction of three-dimensional molecular models and writing of stereo-chemical formulas. Students` strategies for the construction of molecular models and for writing stereo-chemical formulas (Questions 1-3, 5-7, 9-11) were determined on the basis of students` comments and observation of the accompanying activities. The purpose of these questions was to find out whether students use certain strategies for constructing molecular models/writing stereo-chemical formulas, and whether they are related to the use of certain kinds of manipulatives or are more a characteristic of the student. In the following questions students were asked to set their priorities concerning the initial type of molecular structure representation when constructing models with different tools (Question 4 - computer program echem, Questions 8 -molecular models set) or writing a stereo-chemical formula (Question 12). The purpose of these questions was to find out whether the priorities among molecular structure representation are a characteristic of the student regardless of the manipulatives used (so it is possible to set a rule that defines her/his priorities), or whether it is more likely to be related to the use of certain kinds of manipulatives. Perception of molecular structures General questions Students were asked to describe on the basis of which properties of a certain molecular structure representation they perceive information about the structure of the molecule (Questions 13-16). Then they were asked to compare different molecular structure representations, used in previous tasks (Questions 17-22). The purpose of these questions was to reveal the reasons for students` priorities towards perception of a molecular structure from certain representations. Specific questions During the continuation of the interview, students were instructed to solve systematically all of the MVT tasks. The procedure was the same in all MVT task sections ( Perception, Perception and Rotation, Perception and Reflection, Perception, Rotation and Reflection ). In the beginning students were left to solve tasks mentally, then they were asked whether they would like to use help tools, and why (Table A5, rows A and B). Afterwards they were asked whether they preferred certain initial molecular structure representations (static image, stereo-chemical formula) during solving of this particular task type, and why (Table A5, row D). Students were also asked whether one of the accessible helptools (three-dimensional molecular models, computer pseudo three-dimensional molecular models) was more useful than on other, and why (Table A5, row E). 1 The approval of the authors of echem (dr. Soloway and his research group at the University of Michigan) to use the program for research purposes was gained prior to testing.

37 xxxviii APPENDICES TO CHAPTER 13 The purpose of these tasks was to find out whether preferences towards a certain initial molecular structure representation and help-tool are dependent on the kind and number of processes involved.

The purpose of this question was to find out whether students understand the rotation of molecules. To get the information about their strategy of solving this kind of task students were asked to comment how they are solving the tasks (Question 28). Specific questions See Table A5 and comments in the paragraph Perception of molecular structures. Reflection of molecular structures General questions about reflection To find out if students understand the reflection of molecules they were asked to describe this process (Question 33). Students were additionally asked to comment on how they are solving the tasks to get information about their strategy (Question 34). Specific questions for particular task section See Table A5 and comments in the paragraph Perception of molecular structures. Rotation and reflection of molecular structures General questions about reflection To get the information about students` strategy of solving tasks, which involve a combination of the processes perception, reflection and rotation,
