Designing and conducting sound and informative experiments is an important aspect of inquiry learning. Students, however, often design experiments that do not allow them to reach conclusions. Considering the difficulties students experience with the process of designing experiments, additional guidance in the form of an Experiment Design Tool (EDT) was developed, together with reflection questions. In this study, 147 pre-university students worked in an online inquiry learning environment on buoyancy and Archimedes’ principle. Students were randomly assigned to one of three conditions, each of which contained a different version of the EDT. Since students’ prior knowledge has been found to influence the amount and type of guidance they need, the versions of the tool differed with respect to the level of guidance provided. A pre- and post-test were administered to assess students’ conceptual knowledge. No overall differences between conditions were found. In a subsequent analysis, students were classified as either low, low-intermediate-, high-intermediate, or high prior knowledge students. For Archimedes’ principle we found that low-intermediate prior knowledge students gained significantly more conceptual knowledge than low prior knowledge students in the fully guided condition. It is hypothesised that students need at least some prior knowledge in order to fully benefit from the guidance offered. 相似文献

Diagrams organize by location. They give spatial cues for finding and recognizing information and for making inferences. In education, diagrams are often used to help students understand and recall information. This study assessed the influence of perceptual cues on reading behavior and subsequent retention. Eighty-two participants were assigned to one of four versions of a node-link diagram. The diagram consisted of header cells on the left and on top. These header cells organized the information in the body cells, which were connected by arrows. We used a between-subjects design with diagram orientation (header types on top or on the left) and cues orientation (arrows top–down or left–right) as independent variables. Reading process was measured through eye-tracking. Learning performance was assessed with a post test. The results showed that perceptual cues and header content had an additive effect on reading behavior. The reading patterns were strongest when the arrows and category headers both pointed in the same direction. This was reflected in recall. Participants performed better on post-test questions oriented on categories. 相似文献

Inquiry learning is an educational approach in which learners actively construct knowledge and in which performing investigations and conducting experiments is central. To support learners in designing informative experiments we created a scaffold, the Experiment Design Tool (EDT), that provided learners with a step-by-step structure to select variables and to assign values to these variables, together with offering built-in heuristics for experiment design. To further structure the students’ approach, the EDT was offered within a set of detailed research questions which again were grouped under a set of broader research questions. Learning results for learners who worked with the EDT were compared to results for learners in two control conditions. In the first control condition, learners received only the detailed research questions and not the EDT; in the second control condition, learners received only the limited set of general research questions. In all conditions, learners conducted their experiments in an online learning environment about the physics topic of Archimedes’ principle. Conceptual knowledge was measured before and after the intervention using parallel forms of a knowledge test. Overall results showed significant learning gains in all three conditions, but no significant differences between conditions. However, learners who started with low prior knowledge showed a significantly higher learning gain in the EDT condition than in the two control conditions. This result indicates that the effect of providing learners with scaffolds does not follow a “one-size-fits-all” principle, but may depend on specific learner characteristics, such as prior knowledge. 相似文献

Model progression denotes the organization of the inquiry learning process in successive phases of increasing complexity. This study investigated the effectiveness of model progression in general, and explored the added value of either broadening or narrowing students?? possibilities to change model progression phases. Results showed that high-school students in the ??standard?? model progression condition (n?=?19), who could enter subsequent phases at will, outperformed students from a control condition (n?=?30) without model progression. The unrestricted condition (n?=?22) had the additional option of returning to previous phases, whereas the restricted condition (n?=?20) disallowed such downward progressions as well as upward progressions in case insufficient knowledge was acquired. Both variants were found to be more effective in terms of performance than the ??standard?? form of model progression. However, as performance in all three model progression conditions was still rather weak, additional support is needed for students to reach full understanding of the learning content. 相似文献

Many individuals throughout Europe acquire knowledge and skills in an informal manner for which they find no official recognition. Procedures for assessment and accreditation are meant to help individuals in finding recognition of previously gained competencies. The CREDIT (Capabilities, Registration, Evaluation, Diagnosis and advice through Internet Technology) project develops a computer system that supports the assessment and accreditation process and provides advice on further training possibilities tailored to the level of knowledge and skills of individuals. 相似文献
