While previous research has examined outcomes related to academic rigor, mixed findings have resulted from differing conceptualizations of rigor as well as varying methodological approaches. Defining rigor as those in-class practices and assignments that require students to engage in deep learning and demonstrate cognitive complexity, we use…

Policy documents in science education suggest that even at the earliest years of formal schooling, students are capable of constructing scientific explanations about focal content. Nonetheless, few research studies provide insights into how to effectively provide scaffolds appropriate for late elementary-age students' fruitful creation of…

Vygotsky speculated that parents play an important role in the intellectual development of their children, and that this role includes the transfer of expectations related to their children's academic achievement. Consequently, different parents can produce different contexts of academic achievement for their children. The participants were 215…

Summarizes a study of instruments developed for use in assessing aspects of science curriculum and instruction. (PB)

Two models were identified for criterion-referenced tests, one based on the assumption of a continuous achievement variable and the other assuming a dichotomous or binary variable. Several test characteristics were examined and contrasted for the two models, including the distribution of scores, establishment of a cutting score, test length, item…
