Pena-Sandoval, Cesar – AERA Online Paper Repository, 2023
Conceptions about the role of evaluation are crucial in what educators believe and do in assessing student learning; these conceptions influence their practices and should be consistent with the jurisdictional and political frameworks in which they work. While a great deal has been done regarding experienced teachers' conceptions about evaluation,…

Cole, Renée S.; Muniz, Marc; Harvey, Erica; Sweeney, Robert; Hunnicutt, Sally – Journal of Chemical Education, 2020
In this guided inquiry experiment, students extract catecholase enzyme from apples to catalyze the oxidation of catechol. They follow the reaction using the UV--vis absorbance of the "p"-benzophenone produced to determine the Michaelis-Menten kinetic parameters. Students make selected experimental choices within a structured framework…

Johnson, Philip – School Science Review, 2020
Earthbound manifestations of gravity in falling objects are distorted by the large mass and size of the Earth. Movement is also affected by air resistance. This article questions whether an approach based on everyday observations is necessarily the best starting point for introducing the idea of Newtonian gravity. Instead, a theoretical approach…
