In recent years, studies by education researchers indicate that, despite various instructional methods to enhance the conceptual understanding of seasons, the reasons for the formation of seasons and the processes involved are still not fully grasped. This research aims to investigate the fundamental reasons for the difficulties in comprehending…

High-quality professional development is needed to prepare teachers to help students learn how to conduct online academic research and meet Common Core State Standards for English Language Arts. This study created and evaluated a Web-based professional development program with five instructional modules designed to prepare middle-school teachers…

The research partnership among university faculty, information technology graduate students, and science content experts from school districts developed the Web-based two-dimensional and three-dimensional virtual reality science games. The games were implemented to engage middle school students in learning, retaining, and applying newly acquired…

This paper describes five growth points in linking representations of function developed from a study of secondary school learners. Framed within the cognitivist perspective and process-object conception of function, the growth points were identified and described based on linear and quadratic function tasks learners can do and their strategies…

This paper reports on the results of a study investigating the potential to embed Informal Statistical Inference in statistical investigations, using TinkerPlots, for assisting 8th grade students' informal inferential reasoning to emerge, particularly their articulations of uncertainty. Data collection included students' written work on a…

The importance of adolescent literacy is well established, and the topic continues to be of both local and national interest. Practitioners need to know not only which programs and practices appear effective, but which have the scientific evidence to support that claim. To identify effective programs and practices for general education students in…

Students learned in civics lessons in the German Democratic Republic (GDR, or East Germany) that their socialist society uniquely guaranteed all individuals the right to work, and that, as good socialists, they had the duty to take on socially meaningful work. Using the example of a video recording of an East German civics lesson and its…

With COVID-19 continuing to make meeting face-to-face impossible, the Canadian Mathematics Education Study Group/Groupe Canadien d'Étude en Didactique des Mathématiques (CMESG/GCEDM) executive decided that, for the first time, the CMESG/GCEDM meeting would be held virtually. By necessity, the program had to be much compressed with no topic…

"The Spalding Method"[R] is a language arts program for grades K-6 that uses explicit, integrated instruction and multisensory techniques to teach spelling, writing, and reading. The program and its textbook, "The Writing Road to Reading," provide 32 weeks of lesson plans. Students work on program materials in spelling,…

Action research, particularly done by teachers, has had a contentious, decades-long history. As a form of social inquiry, action research has been designed to make it easier for members of social groups to create social change within their communities. Rather than conducting research that focuses on an outcome, action researchers focus on the…

The motivation for this paper is the authors' recent work on several randomized control trials in which they found the primary result, which averaged across subgroups or sites, to be moderated by demographic or site characteristics. They are led to examine a distinction that the Institute of Education Sciences (IES) makes between "confirmatory"…

We investigated prospects for reported sustainable adoption and sharing of an educational innovation through survey research including online questionnaires and telephone interviews. This investigation is part of the Scaling-Up SimCalc experimental program, which combines dynamic representational algebra software (SimCalc MathWorlds) with…

Randomized trials of educational interventions often face logistical hurdles (Cook, 2002). For example, sometimes they are prevented from reaching their full-term. This would happen if, as a condition of participation, subjects insist on receiving the treatment program within a certain timeframe. This timeframe may be shorter than the full-term…

The Institute of Education Sciences (IES) publishes practice guides in education to bring the best available evidence and expertise to bear on current challenges in education. Authors of practice guides combine their expertise with the findings of rigorous research, when available, to develop specific recommendations for addressing these…

This study examines trends in American students' growth trajectories in reading and math achievement over the past three decades. Drawing upon multiple sources of national assessment data, cohort analyses provide new evidence on the stability and change of national academic growth curves. The emerging trends imply a tripartite pattern where…
