Documenting how students with learning disabilities (LD) initially conceive of fractional quantities, and how their understandings may align with or differ from students with mathematics difficulties, is necessary to guide development of assessments and interventions that attach to unique ways of thinking or inherent difficulties these students…

Background: Density is difficult to learn and teach in middle schools. This study, hypothesizing that the density concept develops as part of a conceptual system, used a conceptual change approach to teaching density. The approach emphasized the use of multiple strategies to teach the density concept and the associated concepts in the conceptual…

This article undertakes a comparison of competency-based training (CBT) systems in a number of countries with the purpose of drawing lessons to support Ghana and other countries in the process of CBT implementation. The study focuses on recognition of prior learning and involvement of industry since these features seem crucial in achieving…

The aim of this study is to investigate the impact of teaching social studies with the help of CT on pupils' achievement in social studies. A history, geography and culture oriented theme was selected from the social studies curriculum for the research, Turks on the Silk Road. A multimedia CD, documentaries, PowerPoint and so on were used to teach…

The assessment of university students' economic knowledge has become an increasingly important research area within and across countries. Particularly, the different influences of prior education, native language, and gender as some of the main prerequisites on students' economic knowledge have been highlighted since long. However, the findings…

Previous studies in Malang, Indonesia, showed that there were the failure biology learning caused by not only the low students' prior knowledge, but also biology learning model has not improved the students' critical thinking skills yet, which affected the low of cognitive learning outcomes. The learning model is required to improve students'…

Prior learning assessment (PLA) is the process of evaluating learning, regardless of when or where the learning occurred, and, if the learning is at the college level, awarding college credit to the possessor of that learning. This article provides an overview of the PLA program at a large public U.S. institution and presents the findings of the…

Conversational agents that draw on the framework of academically productive talk (APT) have been lately shown to be effective in helping learners sustain productive forms of peer dialogue in diverse learning settings. Yet, literature suggests that more research is required on how learners respond to and benefit from such flexible agents in order…

Background/Context: Across the United States, secondary school curricula are intensifying as a growing proportion of students enroll in high-level academic math courses. In many districts, this intensification process occurs as early as eighth grade, where schools are effectively constraining their mathematics curricula by restricting course…

The present study incorporates a student response system (SRS) as a means to engage students in a flipped classroom and promote active learning. While the effectiveness of such systems with regard to student learning has been well documented in disciplines that are dominated by lecture-based instruction, no studies have compared the effectiveness…

The field of Instructed Second Language Acquisition (ISLA) has expressed interest in pursuing a research agenda that expands the current heritage language (HL) strand of research to investigate how this heterogeneous population re-learns their family language, and how this experience differs from that of second language (L2) learners. This…

A two-step Bayesian propensity score approach is introduced that incorporates prior information in the propensity score equation and outcome equation without the problems associated with simultaneous Bayesian propensity score approaches. The corresponding variance estimators are also provided. The two-step Bayesian propensity score is provided for…

Video comprehension involves interpreting both sounds and images. Research has shown that processing an aural text with relevant pictorial information effectively enhances second/foreign language (L2) listening comprehension. A hypothesis underlying this mixed-methods study is that a visual-only silent film used as an advance organiser to activate…

This multiple case study investigated how college students with diverse ethno-linguistic backgrounds used chemistry vocabulary as a way to look at their discursive identities and cultural border crossings during first semester general chemistry laboratories. The data were collected in two major forms: video-taped laboratory observations and…
