Research in computer-supported collaborative learning has indicated that conversational agents can be pedagogically beneficial when used to scaffold students' online discussions. In this study, we investigate the impact of an agile conversational agent that triggers student dialogue by making interventions based on the academically productive talk…

This study examined the effects of prior domain knowledge and learning sequences on learning with concept mapping and hypertext. Participants either made a concept map in a first step and then read the hypertext's contents combined with concept mapping (high activating condition), or they read the hypertext's contents first and then made a concept…

This article details a study that investigated 55 elementary pre-service teachers' content knowledge about density. Using a mixed-methods approach, pre/post face-to-face interviews and pre/post concepts maps (Cmaps) were used as data to document changes in teacher knowledge which occurred over a 15-week science methods course. Thematic analysis…

In this paper, we explore the use of concept maps (Cmaps) as instructional materials prepared by teachers, to foster the understanding of chemistry. We choose fireworks as a macroscopic event to teach basic chemical principles related to the Bohr atomic model and matter-energy interaction. During teachers' Cmap navigation, students can experience…

Analogies are ubiquitous during instruction in science classrooms, yet research about the effectiveness of using analogies has produced mixed results. An aspect seldom studied is a model of instruction when using analogies. The few existing models for instruction with analogies have not often been examined quantitatively. The Teaching With…

This study explored the effects of prior knowledge (high vs. low; HPK and LPK) and concept-map structure (hierarchical vs. network; HS and NS) on disorientation, cognitive load, and learning from non-linear documents on "the infection process of a retrograde virus (HIV)". Participants in the study were 24 adults. Overall subjective ratings of…

This paper reports the use of quantitative and qualitative measures of university student learning during teaching in psychiatry. Concept mapping, pre-and post test scores and performance in written assignments were used to measure the quality of change in personal understanding and to show the ways that the knowledge-targets of the course were…

Determining students' knowledge structure is important for assessing what a learner knows about a domain of knowledge. Traditional assessment methods are not always appropriate for exploring students' knowledge structure and changes during the learning period. This study investigates how the existing knowledge structure of the learners interacts…

This investigation was designed to determine the influence of metaphorical priming on students' comprehension of issues and concepts pertaining to the U.S. Constitution when students studied the subject matter in a problem-based hypermedia instructional system. Sixty-five high school seniors studied the system for 5 days after receiving relevant,…

Student-centered approach of scoring the concept maps consisted of three elements namely symbol system, individual portfolio and scoring scheme. We scored student-constructed concept maps based on 5 concept map criteria: validity of concepts, adequacy of propositions, significance of cross-links, relevancy of examples, and interconnectedness. With…

Maps or graphical browsers of structural knowledge allow the user of a hypertext system to navigate from node to node through the structure as they portray the links between concepts spatially. This study examined the results of using two different graphical browsers that provide different amounts of information about the structure of the…

Reports on the relationship between students' propositional knowledge, measured by concept mapping tasks, and their study strategies, measured by self-report questionnaires, as it relates to the concept of photosynthesis as presented in a first-year biology course. Results indicate that involved, purposeful study strategies, prompted by relevant…
