This mixed-methods study was designed to compare the learning gains of seventh-grade students (N = 417) taught a 4-week conceptual change unit on density using either a student-centered, guided inquiry-based approach or a more direct, teacher-centered instructional strategy. Application of a multilevel model to data obtained from the…

This study investigated science classroom discourse in terms of the types of teacher discursive moves (TDMs) and the relationships between the types of TDMs and student-led cognitive contributions in different science concepts by considering the classroom context. An experienced seventh-grade science teacher and her 19 students were engaged in…

The decreasing number of young students pursuing science careers has become a rising concern worldwide, particularly in China. Educational programs with empirical evidence of promoting young students' pursuit of science careers are still lacking. Here, drawing on the existing literature, we designed and implemented a 3-day quasi-apprenticeship…

The current study aimed to make students discover the multidimensional structure of Socio-scientific Issues (SSI) using the SEE-STEP model. Nine-step module has been designed to help students' discover the aspects of the SSI in the implementation process of the research. This research was based on qualitative methodology in determining the study…

There is growing evidence that science capital (science-related forms of social and cultural capital) and family habitus (dispositions for science) influence STEM career decisions by youth. This study presents reliability and validity evidence for a survey of factors that influence career aspirations in science. Psychometric properties of the…

Educational researchers have long noted the apparent link between positive student attitudes and a student's desire to continue their study of particular subjects beyond the compulsory years of schooling, with much of the research motivated by concerns around declining student participation rates in high-school and university. However,…

In longitudinal studies, measurement invariance is required to conduct substantive comparisons over time or across groups. In this study, we examined measurement invariance on a recently developed instrument capturing student preferences for seven instructional strategies related to science learning and career interest. We have labeled these seven…

The increase in global migration and the prioritization of English as an international language have resulted in science learning environments that include students whose primary language differs from the language of instruction. This worldwide phenomenon is not limited to geographical regions but occurs where diverse populations representing…

Despite the inherent potential of cooperative learning, there has been very little research into its effectiveness in middle school laboratory classes. This study focuses on an empirical comparison between cooperative learning and individual learning in the school science laboratory, evaluating the quality of learning and the students' attitudes.…

A systems-based classroom intervention on environmental education was designed for seventh grade students; the results were evaluated to see its impact on the development of systems thinking skills and standard science achievement and whether the systems approach is a more effective way to teach environmental issues that are dynamic and complex. A…

Internationally, efforts to increase student interest in science, technology, engineering, and mathematics (STEM) careers have been on the rise. It is often the goal of such efforts that increased interest in STEM careers should stimulate economic growth and enhance innovation. Scientific and educational organizations recommend that efforts to…

The purpose of this study was to use text mining analysis of early adolescents' online essays to determine their knowledge of global lunar patterns. Australian and American students in grades five to seven wrote about global lunar patterns they had discovered by sharing observations with each other via the Internet. These essays were analyzed for…

Over the past twenty-five years researchers have been concerned with understanding the science student. The need for such research is still grounded in contemporary issues including providing opportunities for all students to develop scientific literacy and the failure of school science to connect with student's lives, interests and personal…

This paper reports multi-layered analyses of student learning in a science classroom using the theoretical lens of Distributed Cognition (Hollan et al. 1999; Hutchins 1995). Building on the insights generated from previous research employing Distributed Cognition, the particular focus of this study has been placed on the "public space of…

Science literacy leading to fuller and informed participation in the public debate about science, technology, society, and environmental (STSE) issues that produce justified decisions and sustainable actions is the shared and central goal of the Pacific CRYSTAL Project. There is broad agreement by science education researchers that learners need…
