In this article we compare outcomes of an open-inquiry and an expository version of a chemistry laboratory experiment at university level for 190 students. The aim of the study was to investigate if these two versions would result in different outcomes depending on the students' attitudes towards learning. We used a questionnaire to find out their attitude position prior to the laboratory experiment. The outcome in the different versions of the experiment was evaluated by interviews, questions asked during the experiment and students self-evaluations. The main findings were that the open-inquiry version shows the most positive outcomes regarding learning outcome, preparation time, time spent in the laboratory and student perception of the experiment. The students with low attitude position needed more support to meet the challenge of an open-inquiry experiment, the support being a clearer explanation of the aims, and feedback from the instructor during the experiment.

To enhance the learning outcomes achieved by students, learners undertook a computer-simulated activity based on an acid-base titration prior to a university-level chemistry laboratory activity. Students were categorized with respect to their attitudes toward learning. During the laboratory exercise, questions that students asked their assistant teachers were used as indicators of cognitive focus. During the interviews, students' frequency and level of spontaneous use of chemical knowledge served as an indicator of knowledge usability. Results suggest that the simulation influenced students toward posing more theoretical questions during their laboratory work and, regardless of attitudes, exhibiting a more complex, correct use of chemistry knowledge in their interviews. A more relativistic student attitude toward learning was positively correlated with interview performance in both the control and treatment groups.

To gain insight into factors associated with changes in attitude toward learning chemistry, six students who displayed major attitude changes were identified through a pre- and post-course attitude questionnaire administered to sixty-six first-year university chemistry students. Those with largest attitude changes, both positive and negative, were selected to highlight the contrast between students. The six students were interviewed; descriptions of their one-semester chemistry course experiences were analyzed to identify factors associated with their change in attitude. A positive attitude change was associated with evidence of motivated behaviour, while a negative change was linked to less motivated behaviour. Students addressed similar factors in the educational setting, but students with positive attitude changes exhibited fewer negative views of educational factors, while students with negative attitude changes showed an opposite pattern. Since the same factors, students’ perceived level of teacher empathy for their efforts at chemistry learning, affected both groups, this indicates a possibility for changes in educational setting beneficial to all students.
