STEM instruction often uses visual representations. To benefit from these, students need to understand how representations show domain-relevant concepts. Yet, this is difficult for students. Prior research shows that physical representations (objects that students manipulate by hand) and virtual representations (objects on a computer screen that…

This study (Note 1) investigates potential differences in language use between genders, by applying a modified model of thought representation. Our hypothesis is that women use more direct forms of thought representation than men in modern spoken British English. Women are said to favour "private speech" that creates intimacy and…

The national science standards, along with prominent researchers, call for increased focus on scientific argumentation in the classroom. Over the past decade, researchers have developed sophisticated online science learning environments to support these opportunities for scientific argumentation. Assessing the quality of dialogic argumentation,…

Numerous studies have affirmed the value of asynchronous online communication as a learning resource. Several investigations, however, have indicated that discussions in asynchronous environments are often neither interactive nor coherent. The research reported sought to develop an enhanced understanding of interactional coherence, argumentation,…

This study examined the representation of knowledge in text writing in 20 ten-year-old children and 20 adults in the Netherlands. The research analyzed the use of clause linking devices to compose larger text units. Special attention was given to the use of causal relational markers and the extent to which causal relations within the texts matched…

This study investigated the representations that readers construct for narratives describing a sequence of events. Participants read narratives describing 4 successive events in chronological order (Event 1, Event 2, Event 3, Event 4 [E1, E2, E3, E4] Experiment 1) or in nonchronological order with E1 being mentioned in a flashback (E2, E3, E1,…
