Student interest in plants is lacking. Therefore, we investigated potential drivers of situational interest in cultivated plants and interactions between different dimensions of interest, i.e. topic, context and learning activity. A total of 462 high school students (14-17 years of age) rated two sets of questionnaire items combining eight plants…

The teleological bias, a major learning obstacle, involves explaining biological phenomena in terms of purposes and goals. To probe the teleological bias, researchers have used acceptance judgement tasks and preference judgement tasks. In the present study, such tasks were used with German high school students (N = 353) for 10 phenomena from human…

The purpose of this research is to investigate the effects of a hands-on lab activity that aims at fostering the ability to reason across levels. A total of 197 students (18 years of age) participated in a randomized,…
