Impacts of TELS Projects
TELS assessment results show that TELS projects generally result in significant gains by level of prior knowledge and related gains to other instructional variables. These studies show that well-designed projects that include pilot testing and refinement in classroom settings generally improve the scientific understanding of students with both high and low prior knowledge. Taken together, these studies demonstrate that scientific visualizations embedded in inquiry projects can improve student learning of complex science concepts.
Below are sample results from a longitudinal study by Lee & Linn (2008). For more details on the impact of TELS projects, explore our publications.
