Journal of Science Education and Technology Vol. 24, No. 2 (April 2015) pp. 378–395
Modeling and argumentation are two important scientific practices students need to develop throughout school years. In this paper, we investigated how middle and high school students (N = 512) construct a scientific argument based on evidence from...
The Effect of Two-Dimensional and Stereoscopic Presentation on Middle School Students' Performance of Spatial Cognition Tasks
Journal of Science Education and Technology Vol. 19, No. 1 (February 2010) pp. 90–103
We investigated whether and how student performance on three types of spatial cognition tasks differs when worked with two-dimensional or stereoscopic representations. We recruited nineteen middle school students visiting a planetarium in a large...
Science Teacher Vol. 79, No. 3 (March 2012) pp. 60–65
Scientists, and science in general, move from the unknown to increasing levels of certainty. Teaching students about science means encouraging them to embrace and investigate the unknown, make reliable scientific claims, justify those claims with...
Elementary Students' Learning of Materials Science Practices through Instruction Based on Engineering Design Tasks
Journal of Science Education and Technology Vol. 19, No. 6 (December 2010) pp. 580–601
Materials science, which entails the practices of selecting, testing, and characterizing materials, is an important discipline within the study of matter. This paper examines how third grade students' materials science performance changes over the...
Science Teacher Vol. 79, No. 7 (October 2012) pp. 38–42
Systems thinking suggests that one can best understand a complex system by studying the interrelationships of its component parts rather than looking at the individual parts in isolation. With ongoing concern about the effects of climate change,...
International Journal of Science Education Vol. 36, No. 14 (2014) pp. 2391–2420
We investigated how students articulate uncertainty when they are engaged in structured scientific argumentation tasks where they generate, examine, and interpret data to determine the existence of exoplanets. In this study, 302 high school students ...
Teaching with Interactive Computer-Based Simulation Models: Instructional Dilemmas and Opportunities in the High-Adventure Science Project
School Science and Mathematics Vol. 118, No. 5 (2018) pp. 190–200
The purpose of this descriptive study was to examine teacher instructional dilemmas and opportunities that emerged when students worked with interactive computer-based simulation models during the High-Adventure Science (HAS) project. The...
Journal of Research in Science Teaching Vol. 48, No. 9 (November 2011) pp. 1079–1107
Science education needs valid, authentic, and efficient assessments. Many typical science assessments primarily measure recall of isolated information. This paper reports on the validation of assessments that measure knowledge integration ability...
Science Education Vol. 87, No. 4 (2003) pp. 490–516
Examines the implementation and adaptation of Kids as Global Scientists (KGS), an inquiry-based, technology-rich middle school environment. Examines three classrooms of urban teachers in high-poverty environments and two classrooms of maverick...
CALICO Journal Vol. 26, No. 3 (May 2009) pp. 529–544
In this study, we focus on particle errors and discuss an annotation scheme for Korean learner corpora that can be used to extract heuristic patterns of particle errors efficiently. We investigate different properties of particle errors so that they ...
Journal of Astronomy & Earth Sciences Education Vol. 2, No. 1 (2015) pp. 17–26
Stereoscopy's potential as a tool for science education has been largely eclipsed by its popularity as an entertainment platform and marketing gimmick. Dozens of empirical papers have been published in the last decade about the impact of stereoscopy ...
COBRIX: A Physical Computing Interface for Blind and Visually Impaired Students to Learn Programming
Society for Information Technology & Teacher Education International Conference 2017 (Mar 05, 2017) pp. 727–733
Despite national attention on computer science, there is a significant lack of educational resources for visually impaired or blind population to get introduced to learn to program. This population should be active participants, rather than passive...
Factors Influencing Students' Satisfaction and Dissatisfaction with the Online Learning Community for Korean High School Science Classes
Science Education International Vol. 17, No. 4 (December 2006) pp. 275–286
The purpose of this study was to investigate factors influencing students' satisfaction and dissatisfaction with an Online Learning Community (OLC). The OLC was a Web-based system that was used to supplement school science curriculum. Data was...
