The expertise reversal effect occurs when learner's expertise moderates design principles derived from cognitive load theory. Although this effect is supported by numerous empirical studies, indicating an overall large effect size, the effect was never tested by inducing expertise experimentally and using instructional explanations in a…

In an attempt to address shortcomings revealed in international assessments and lamented in legislation, many schools are reducing or eliminating elective courses, applying the rationale that replacing "non-essential" subjects with core subjects, such as mathematics and language arts, will better position students in the global market. However,…

Laboratory studies have demonstrated the long-term memory benefits of studying material in multiple distributed sessions as opposed to one massed session, given an identical amount of overall study time (i.e., the "spacing effect"). The current study goes beyond the laboratory to investigate whether undergraduates know about the advantage of…

This paper presents an analysis of the scientific reasoning of a dyad of secondary school students about the phenomenon of dissolution of gases in water as they work on this in a simulated laboratory experiment. A web-based virtual laboratory was developed to provide learners with the opportunity to examine the influence of physical factors on gas…

The study investigated the effectiveness of causal words embedded in Chinese texts to explicitly indicate causal links between the described events. Primary school students with different levels of reading expertise participated in the experiment that compared an embedded casual-words format with the original no-causal-words format. An interaction…

Much current research has focused on epistemic beliefs of students. However, teachers' epistemic practices are also important to study because they may influence students' epistemic beliefs. The standards for justification for different content areas necessitate that teachers use diverse pedagogical practices designed to help students develop…

Acquiring complex conceptual knowledge requires learners to self-regulate their learning by planning, monitoring, and adjusting the process but they find it difficult to do so. In one experiment, we examined whether learners need broad systems of support for self-regulation or whether they are also able to learn with more economical support…

Participants included 112 Year 1 and 54 Year 4 undergraduate preservice teachers, 21 continuing education students, and 18 honors psychology students. The programs provided different exposure to inquiry. Groups were compared on the importance attributed to specific building blocks (strategic demands) of inquiry instruction and learning, and…

The purpose of this study was to investigate the effects of representation sequences and spatial ability on students' scientific understandings about the mechanism of breathing in human beings. 130 seventh graders were assigned to two groups with different sequential combinations of static and dynamic representations: SD group (i.e., viewing…

This study aimed to identify if complementing representations of concrete objects with representations of abstract objects improves students' conceptual understanding as they use a simulation to experiment in the domain of "Light and Color". Moreover, we investigated whether students' prior knowledge is a factor that must be considered in deciding…

We report the effect of different sequences of high vs low levels of instructional guidance on children's immediate learning and long-term transfer of simple experimental design procedures and concepts, often called "CVS" (Control of Variables Strategy). Third-grade children (N = 57) received instruction in CVS via one of four possible orderings…

This paper aims to study the relationship between questioning and the quality of knowledge constructed in a CSCL context. In previous studies, different units of analysis are employed and the patterns of relationships are not consistent for different age groups. The analytic units of a thread, an individual, and a group are employed in this study,…

As the need for instructing a globalized workforce increases, instructional designers must embrace the constraints and the opportunities these projects provide in order to move the field of cross-cultural instructional design (ID) forward. Cross-cultural projects offer multiple avenues for growth in ID practice, overcoming cultural barriers, and a…

This study considers the case of a tutor whose students repeatedly evidenced significantly superior critical thinking in summative assessment. For the purpose of surfacing appropriate pedagogical action to promote critical thinking (Bassey, "Case Study Research in Educational Settings," 1999), the singularity of one tutor's reported pedagogical…

This article outlines an instructional paradigm that guides the design of interventions that build skills in computer-mediated communication (CMC). It is applicable to learning at multiple levels of communicative proficiency and aims to heighten awareness, the understanding of the impact of media configurations, the role of cultures and social…
