This article examines the implications of argument-based validity for the continued development of dynamic assessment (DA) research and practice. We propose that the move toward validation as a process of interpretation and evidence-based argument is commensurable with DA but that fundamental ontological differences with conventional approaches to…

Skepticism about the limits of online learning is as old as online learning itself. As with other technologically-driven innovations in pedagogy, there are deep-seated worries that important educational goods might be effaced or obscured by the ways of teaching and learning that online methods allow. One family of such worries is inspired by…

Visual working memory (VWM) has a limited capacity of approximately 3-4 visual objects. Current theories of VWM propose that a limited pool of resources can be flexibly allocated to objects, allowing them to be represented at varying levels of precision. Factors that influence the allocation of these resources, such as the complexity and…

The main purpose of this research is to determine the relationship between prospective teachers' smartphone addiction and interaction anxiety. For this purpose, quantitative research was carried out within the relational screening model. The population of the research was composed of senior students and pedagogical formation students from Inonu…

The aim of this study was to develop a coding scheme rooted in the Knowledge Building model, named Conversational Functions for Knowledge Building (CF4KB), to analyze students' interactions in an online undergraduate course. In order to develop the coding scheme, we analyzed students discourse and identified the kinds of "Conversational…

Mathematics classroom interaction has often been described as an important context for involving all students. However, this article shows that teacher-student-interaction is still not really in the focus of teachers' attention. Based on classroom video studies, some authors hypothesize that the implicitness of establishing norms and practices is,…

Teachers incorporate information from various sources as they form their academic expectations for students. The student record of prior achievement is the most salient factor that educators use to form their expectations for children's achievement. Research on the factors that influence educator expectations has primarily focused on the ways…

Learning robotics can be performed individually or as a collaborative problem-solving activity. Effective pedagogy is based on the latter. In this paper, we offer a work-in-progress report of an observational analysis of parent-child dyads engaged in an educational robotics workshop in a Science Center. We chose this context because learning…

Students' understandings of foundational concepts such as noncovalent interactions, pH and pK[subscript a] are crucial for success in undergraduate biochemistry courses. We developed a guided-inquiry activity to aid students in making connections between noncovalent interactions and pH/pK[subscript a]. Students explore these concepts by examining…

Theory has been an object of interest for HCI researchers working on questions related to disciplinary identity and maturity. And recently there have been empirical studies of theory use in HCI research publications. These recent studies are crucial for enriching our understanding of how HCI researchers use theoretical knowledge objects like…

The analysis of log data generated by online educational systems is an important task for improving the systems, and furthering our knowledge of how students learn. This paper uses previously unseen log data from Edulab, the largest provider of digital learning for mathematics in Denmark, to analyse the sessions of its users, where 1.08 million…

Drawing causal inference with observational studies is the central pillar of many disciplines. One sufficient condition for identifying the causal effect is that the treatment-outcome relationship is unconfounded conditional on the observed covariates. It is often believed that the more covariates we condition on, the more plausible this…

What can we learn from a pause? This dissertation examines whether a pause between speaking turns in a conversation (a gap) can change how we view that conversation and its participants (a gap effect). In particular, it asks whether the length of a gap can influence interactional attributions--that is, attributions of the participants' engagement…

Like general theories of human communication, previous research into second language (L2) communication strategies (CSs) has also been characterized on either interactional conceived account or cognitively conceived one. However, this paper is a critical attempt to show that CSs' full significance can only be understood if the domain of CSs…

This observational study examined the Iranian mothers' interaction with their typically developing children aged 13-18 months during free play at home (n = 40). The first aim was to determine the main type of Iranian maternal verbal responsiveness. Another aim was to investigate the impact of concurrent prediction of maternal verbal responsiveness…
