Chemistry classroom analysis

In the third study (Van Vorst, 2013), factor analysis extracted emotion- and value-related scales (see Table 2). Students had to rate their interest in learning chemistry knowledge starting from a presented context. As this situation was rated without an explicit reference to content knowledge, items asked for interest in the introductory context as well as if it was used in the chemistry classroom. Because situations did not include an explicit learning activity, activity-related interest scales could be excluded. A reason for the extraction of both valences can be seen in the procedure which combined a large sample with a variety of situations to be rated with regard to different characteristics. 

Visualizations such as computerized molecular modelling foster conceptual understanding, modelling skills, and transfer among multiple representations. Utilization of computers and sensors in chemistry classrooms for collection and analysis of data may help strengthen students graphing and problem solving skills. 

Qualitative analysis. This is summarized in a couple of pages in an essay in Chapter 16 in the Chemistry Beyond the Classroom section. An extended discussion of the qual scheme and the chemistry behind it belongs in a lab manual, not a textbook.

However, examination reports confirm the narrow implementation of chemistry inside a classroom. Significant numbers of students reportedly face difficulty not only in applying their chemistry knowledge to solve problems but surprisingly also in handling basic skills [12]. The A level November 2007 report for paper 5 Planning, Analysis and Evaluation [14] underlines students difficulties with some of the basic skills and confirms the above findings ...
