Providing scientific explanations for natural phenomena is a fundamental aim of science; therefore, scientific explanation has been selected as one of the key practices in science education policy documents around the world. To further elaborate on existing educational frameworks of scientific explanation in K-12, we propose a learning progression…

The aim of the present study is to enable future studies into students' attitudes toward science, and related constructs, by developing and validating an instrument suitable for cross-sectional designs. Following a thorough review of the literature it was determined that many extant instruments included design aspects that appeared to be limited…

We present a new system for automated scoring of graph construction items that address complex science concepts, feature qualitative prompts, and support a range of possible solutions. This system utilizes analysis of spatial features (e.g., slope of a line) to evaluate potential student ideas represented within graphs. Student ideas are then…

The purpose of this mixed-method study was to investigate the changes in high school students' perceptions of fluency with innovative technologies (IT) and the levels of students' scientific inquiry abilities as a result of engaging students in long-term scientific research projects focusing on community-based environmental issues. Over a span of…

Sixty-seven students participated in a study that used path analysis techniques to test a hypothesized structural model of direct and indirect causal effects of students variables on science process skills. Academic ability, biology knowledge, and language preference were found to have significant direct effect, whereas cognitive development,…

Provides evidence to support the conclusion that relationships exist among Piagetian levels of intellectual development, intelligence quotient, content achievement, and inquiry skills in ninth and tenth grade biology students (N=92). (DS)

This investigation explores how underrepresented urban students made sense of their first experience with high school science. The study sought to identify how students' assimilation into the science classroom reflected their interpretation of science itself in relation to their academic identities. The primary objectives were to examine students'…

Examined is the effectiveness of a smoking-prevention program in modifying high school students' attitudes and values in such categories as health, peer pressure, and social image as related to smoking. The intervention lasted four to six weeks within the framework of ninth- and tenth-grade biology classes. (Author/YP)
