We investigated how the level of variance in students' prior knowledge may have influenced their collaborative interactions and science learning in small groups. We examined learning outcomes from 102 groups from seven science teachers' classes and discourse from two contrasting groups: Homogeneous versus heterogeneous. We examined individual and…

The current study investigated how prior knowledge moderated the effects of three educational technologies ("From Here to There," "DragonBox 12+," and problem sets in "ASSISTments") on seventh-grade students' later algebraic knowledge. Pretest scores only moderated effects of "From Here to There," with…

Technology-enhanced vocabulary learning has gained increasing attention, yet its effectiveness remains inconclusive, with studies reporting mixed findings. Additionally, whether integrating self-regulated learning mechanism (SLM) into such type of learning can further enhance its effectiveness remains underexplored. This study examines the impact…

The current study aimed to contribute to the literature by implementing an intervention that examines the effects of explicit metacognitive strategy training and prompts embedded within a Game-Based Learning Environment (GBLE), "Missions with Monty," on metacognitive monitoring accuracy, game performance, and science knowledge of…

Within a policy climate that is permissive to Dual Language (DL) programs in California and within the social context of the ongoing gentrification of those programs, this case study explored the leadership and organizational structures required to expand DL programs beyond the elementary years. We asked: (1) What organizational arrangements may…

"Learning by doing" involves completing a practice activity through the method of inquiry. This study combined the predict-observe-explain (POE) inquiry method and hands-on doing processes to develop a cycle-mode POED (predict-observe-explain-do) model with an e-learning system to help students complete a practice activity using…

Building on rich training literature, we examined which skills constituting the control-of-variables strategy (CVS) benefit from a comprehensive training, and which develop similarly during content-focused inquiry at ages 10-12. In addition, we examined whether prior knowledge, reasoning abilities, and reading comprehension explain variation in…

Although visual representations are generally beneficial for learners, past research also suggests that often only a subset of learners benefits from visual representations. In this work, we designed and evaluated anticipatory diagrammatic self- explanation, a novel form of instructional scaffolding in which visual representations are used to…

This study was carried out with a total of 75 students attending 9th grade in two high schools affiliated to the Ministry of National Education in Reyhanli district, which hosted many Syrian refugees in Hatay province in the spring semester of 2018-2019 academic years and lasted for three weeks. A total of 75 students, 43 from two different 9th…

It is known that most of learning theories recommended developing the whole personality of learner in all school levels. Integrating among applications and recommendations of several learning theories can create better and effective varied learning environments for all learners. So educators should continue to develop learning and teaching models…

We report on a randomized controlled trial of an intervention that leverages the availability of laptops for all public-school students in the state of Maine. The intervention, called "ASSISTments," provides feedback to students as they solve mathematics homework problems and automatically prepares reports for teachers about student…

The current study investigated the effects of interactive picture-book read-alouds on middle school EFL students' word inference ability and attitudes toward reading in English. To this end, two classes of seventh-grade students from a public middle school in Taiwan participated and were randomly divided into two groups: an interactive…

Background: Recent effectiveness studies have investigated the relationship between two dimensions of effectiveness -- namely, quality and equity. Specifically, the question of whether effective schools can also reduce the initial differences in student outcomes attributed to student background factors has been examined. In this context, the…

In the US, many federal, state and local school improvement policies rely on teacher professional development (PD) to foster classroom change. Past research suggests PD that has a content focus is the most effective, but that even content-focused PD varies in its effectiveness. Through in-depth interviews of teachers participating in a middle…
