The science education field readily recognizes that perceptions about science's claims and nature influence socioscientific decision making. However, sociocultural factors may overshadow these perceptions when people are forced to make personally impacting choices contextualized within actual socioscientific issues. This investigation…

There are widespread policy concerns to improve (widen and increase) science, technology, engineering, and mathematics participation, which remains stratified by ethnicity, gender, and social class. Despite being interested in and highly valuing science, Black students tend to express limited aspirations to careers in science and remain…

We teach a course for elementary education undergraduates that gives students an opportunity to conduct open-ended scientific inquiry and pursue their own scientific questions in much the same way that practicing research scientists do. In this study, we compared what our students say declaratively about the nature of science (NOS) in surveys and…

"Experience" is one of the most used terms in (science) education, and it is recognized as being related to learning (education). Yet "what" experience is and "how" it is related to learning and change remains untheorized. In this paper, we mainly draw on the work of J. Dewey and L. S. Vygotsky but also on M. Bakhtin…

The purpose of this project was to investigate the effects of virtual versus physical manipulation using a simulation-based laboratory activity (SBL) and a microcomputer-based laboratory activity (MBL). Both the SBL and the MBL used computers to collect, graph, and analyze data. A major difference was that the MBL allowed the students to…

That nature and the universe are ordered, uniform, and comprehensible is a starting point in science. However, such worldview presuppositions are often taken for granted, rather than explicitly mentioned, in science and in science class. This article takes a worldview perspective and reports from interviews (N = 26) with upper secondary students…

This exploratory analysis of student attendance at science museums finds that student achievement in science and mathematics is somewhat higher for those students who visited science museums frequently during the school year or summer. The strength of the association with cognitive achievement is sufficiently noteworthy to encourage further…

Scientific literacy reflects "a broad and functional understanding of science for general education purposes" (DeBoer, [DeBoer, G. E., 2000], p. 594). Herein, we present the ongoing development of the Scientific Literacy Assessment (SLA), a work-in-progress measure to assess middle school students' (ages 11-14) scientific literacy.…

This study examines the ways in which teachers provide students with written scaffolds in assessment tasks and the impact of these on students' abilities to demonstrate a core disciplinary proficiency--constructing evidence-based explanations. Data include 76 assessment tasks designed by 33 science teachers and 707 samples of student work. We…

Elementary science standards emphasize that students should develop conceptual understanding of the characteristics and life cycles of plants (National Research Council, 2012), yet few studies have focused on early learners' reasoning about seed structure and function. The purpose of this study is twofold: to (a) examine third-grade…

This study examined and compared students' understanding of nature of science (NOS) with 521 Grade 8 Canadian and Korean students using a mixed methods approach. The concepts of NOS were measured using a survey that had both quantitative and qualitative elements. Descriptive statistics and one-way multivariate analysis of variances examined…

In this study, we produced a documentary which portrays scientists at work and critically evaluated the use of this film as a teaching tool to help students develop an understanding of the nature of science. The documentary, "Life as a Scientist: People in Love with 'Caenorhabditis elegans,' a Soil Nematode" encompasses the…

Research on students' views on nature of science (VNOS) in Asian countries such as China is notably lacking. This study aimed to develop and validate an instrument to measure South China high school students' VNOS. Based on the previously acquired qualitative data, the instrument included seven VNOS dimensions which reflect the crucial…

Previous research showed that primary school children held several misconceptions about genetics of concern for their future lives. Included were beliefs that genes and DNA are separate substances, with genes causing family resemblance and DNA identifying suspects at crime scenes. Responses to this work "blamed" the mass media for these…

The purpose of this study was to investigate the relationship of students' understanding of science knowledge, attitude and decision making on socio-scientific issues (SSI), especially on the issues of nuclear energy in Korea. SSI-focused instructions were developed to encourage students to understand and reflect on knowledge, attitude and…
