Nov 13, 2022 · The analyses revealed 43 challenges at the conceptual, procedural and epistemic level that not only elementary but even university students face during experimentation. Additionally, cognitive biases and preconceptions are identified as a source of such challenges.
Feb 11, 2022 · At the secondary level, science instruction often alternates between fact-oriented lectures and laboratory experiments designed to reinforce key ideas. However, too often these lectures and experiments do not provide a coherent learning experience, and they deny students the opportunity to apply science to an authentic context.
Oct 13, 2017 · Key teaching strategies included: guiding students to provide a rationale for their predictions and hypotheses for experiments; leaving data organization and analysis open-ended; discussing as a class the pros and cons of experimental choices made by different student groups; combining class data to expand sample size; grading lab reports on ...
