Problem posing is a promising teaching method for enhancing motivation and performance in mathematics and more specifically in mathematical modelling. Hence, the goals of our study were twofold: (1) to examine the effects of problem posing on modelling performance, self-efficacy, and task values in solving modelling problems, and (2) to analyze…

In science education, context-based learning is mostly based on problem-oriented tasks [Gilbert, J. K. (2006). On the nature of "context" in chemical education. "International Journal of Science Education", 28(9), 957-976]. Therefore, a relevant question is, how do students integrate the information given in the task into their…

This study attempts to investigate the performance of tenth-grade students in solving quadratic equations with one unknown, using symbolic equation and word-problem representations. The participants were 217 tenth-grade students, from three different public high schools. Data was collected through an open-ended questionnaire comprising eight…

This performance assessment pilot study was a major research component of the overall National Science Foundation funded Redesigned High Schools for Transformed STEM Learning Project. Secondary Earth/Environmental Science students' abilities to translate cognitive knowledge into demonstrable performance-based proficiencies were specifically…

We conducted an experimental study with 192 ninth graders in which we investigated a connection between performance and students' interest and enjoyment using task-unspecific and task-specific questionnaires. Students were randomly assigned to experimental group 1 or to experimental group 2. In group 1, they were asked about their affective…
