The aim of this study was to investigate the effects of the applications of learning together and group investigation methods at different intervals on the features of cooperative learning model. The study sample comprised the sixth, seventh and eighth grade students studying in a public middle school. In the first year of the application,…

This article reports on the development of an online dynamic approach for assessing and improving students' reading comprehension of science texts--the dynamic assessment for reading comprehension of science text (DARCST). The DARCST blended assessment and response-specific instruction into a holistic learning task for grades 5 and 6 students. The…

This study relied on motivational models derived from self-determination theory to explain how garden-based science activities can contribute to minority students' motivation and learning in science class and academic identity in science. Participants were 105 sixth-grade students from primarily low-SES families at two diverse urban schools.…

This teacher-research study responds to the Common Core State Standards (CCSS) call for an integrated model of literacy that simultaneously builds deep content knowledge and develops students' proficiency in writing arguments in science. The author notes that while argument is a cornerstone of the CCSS writing standards, little attention is…

This research is a high-resolution analysis of grade 6 (ages 11-12) children's interview transcripts about the operation of power stations, before and after teaching. The focus of the study was on how children's conceptual development is built at a discursive level, namely how language is used to express changes in their thoughts. The theoretical…

Background: Cognitive conflict has been identified as an important factor for bringing about students' conceptual change. Researchers draw attention to the need to study not only cognitive factors related to cognitive conflict but affective factors as well. Purpose: The purpose of this study was to investigate the contribution of cognitive…

How can water and a penny demonstrate the power of mathematics and molecular theory? Do spelling and punctuation really matter to the human brain? The third of Thomas O'Brien's books designed for 5-12 grade science teachers, "Even More Brain-Powered Science" uses the questions above and 11 other inquiry-oriented discrepant events--experiments or…

Teaching science to diverse learners can be a demanding and challenging task. Teachers may be underprepared and thus unsure of how to best address the needs of their students in their classroom. One approach to helping teachers is through professional development. Yet, programs that focus mainly on science or special education can fail to fully…

Technology offers many opportunities for educators to support teaching, learning and assessment. This paper introduces a project to design and implement a virtual environment (SAVE Science) intended to assess (not teach) middle school students' knowledge and use of scientific inquiry through two modules developed around curriculum taught in middle…

The delta-plot method (Angoff, 1972) is a graphical technique used in the context of test equating for identifying common items with aberrant changes in their item difficulties across administrations or alternate forms. This brief research report explores the effects on equated aggregate scores when delta-plot outliers are either retained in or…

Two experiments using the science topics of Magnetism and Light were conducted with younger learners (Year 5) who had no prior knowledge of the topics, and older learners (Year 6) who had studied the topics previously. Half of the learners were presented the information in auditory form only while the other half were presented the auditory…

The 2006 National Science Board called for new strategies and instructional materials for teachers to better serve English Learners' (EL) needs. Bilingual Collaborative Online Projects in science were created to assist ELs' construction of science knowledge, facilitate academic English acquisition, and improve science learning. Two bilingual…

This study aims at investigating the effects of a teaching intervention, the design of which is informed by evidence from educational theories and research data, on students' images of scientists. A quasi-experimental design with a non-equivalent pre-test-post-test control group (CG) was used to compare the outcomes of the intervention. The…

Recent research has challenged traditional assumptions that scientific practice and knowledge are essentially individual accomplishments, highlighting instead the social nature of scientific practices, and the co-construction of scientific knowledge. Similarly, new research paradigms for studying learning go beyond focusing on what is "in the…

In this paper we explore students' engagement in a new media enhanced problem-based learning (PBL) environment and investigate the characteristics of these environments that facilitate learning. We investigated both student experiences using a new media enhanced PBL environment and the specific elements students found most supportive of their…
