Significant attention is being paid to how assessments aligned to learning trajectories (LTs) can be used as a means to locate students' progress in learning big ideas in mathematics over time. Furthermore, data from LT-aligned assessments have been signaled as key to driving student-centered instruction on a day-to-day basis. For LTs and…

Understanding factors that impact teacher implementation of learning from professional development is critical in order to maximize the educational and financial investment in teacher professional learning. This multi-case qualitative investigation elucidates factors that influence the appropriation of instructional tools associated with…

As science becomes increasingly computationally intensive, the need for computational thinking (CT) and computer science (CS) practices in K-12 science education is becoming paramount. Incorporation of CT/CS practices in K-12 education can be seen in national standards and a variety of allied initiatives. One way to build capacity around an…

The purpose of this research was to examine relationship between the eighth-grade gifted students' perceptions of science learning environment constructive learning environment perception (CLEP) and their motivations motivation to learn science (MLS) to learn science with their intellectual risk-taking (IRT) and science achievement (SA). For this…

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,…

The racial and ethnic makeup of the United States is in constant flux and is expected to experience substantial increases over the next four decades. The problem the American educational system face is attempting to problematize race/racism in its educational system and creating a system to counteract that. The disparity we face grows as teacher…

The racial and ethnic makeup of the United States is in constant flux and is expected to experience substantial increases in racial and ethnic diversity over the next four decades. The problem the American educational system faces is attempting to problematize race/racism in its educational system and creating a system to counteract educational…

The so-called control-of-variables strategy (CVS) incorporates the important scientific reasoning skills of designing controlled experiments and interpreting experimental outcomes. As CVS is a prominent component of science standards appropriate assessment instruments are required to measure these scientific reasoning skills and to evaluate the…

In international large-scale assessments of educational outcomes, student achievement is often represented by unidimensional constructs. This approach allows for drawing general conclusions about country rankings with respect to the given achievement measure, but it typically does not provide specific diagnostic information which is necessary for…

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…

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…

In an experimental study (N = 209), the authors compared the effects of exposure to typical middle-school written science content when presented in the context of the scientific discovery narrative and when presented in a more traditional nonnarrative format on 7th and 8th grade students in the United States. The development of texts was…

The purpose of this study is to present the whole process step-by-step of how a science lesson can be planned and implemented based on Multiple Intelligences (MI) theory. First, it provides the potential of the MI theory for science teaching and learning. Then an MI science lesson that was developed based on a modified model in the literature and…

This study explored how inquiry-based teaching and learning processes occurred in two teachers' diverse 8th grade Physical Science classrooms in a Program Improvement junior high school within the context of high-stakes standardized testing. Instructors for the courses examined included not only the two 8th grade science teachers, but also…

The purpose of this research study is to explore year 6, 8 & 11 (13, 15 and 17 years old respectively) Turkish pupils' views about the particulate nature of matter within the context of phase changes. About 300 pupils participated in the study. Questionnaires distributed to year 6, 8 and 11 pupils included 6-item open-ended questions about (a)…
