Reasoning across descriptive levels is a fundamental component of scientific reasoning, particularly in chemistry. Repeatedly, students are seen to confuse features applicable to one level across multiple levels despite instruction. Although many instances of such "levels confusion" have been documented, little is known about the…

This dissertation consists of two articles which discuss the establishment of collective cognitive responsibility in high school mathematics classrooms. I use collective cognitive responsibility as a framework for interpreting the extent to which students see themselves as responsible for building knowledge as a community. I adapted this framework…

The efficacy of video-based sign language (SL) navigation aids to improve Web search for Deaf Signers was tested by two experiments. Experiment 1 compared 2 navigation aids based on text hyperlinks linked to embedded SL videos, which differed in the spatial contiguity between the text hyperlink and SL video (contiguous vs. distant). Deaf Signers'…

The number of videos produced specifically for infants and toddlers has grown exponentially in the last decade. Many of these products make educational claims regarding young children's language development. This study explores infant media producer claims regarding language development, and the extent to which these claims reflect different…

The narrator relates his life's downward spiral and miraculous rebound from severe foot problems using animated bullet points, images, charts, and graphs. "Custom Orthotics Changed My Life" is a work of presentation fiction, or slideshow fiction, in the form of a video with an original soundtrack. The music was composed by David Kettler, a…

This pilot study examined whether refusal assertion as defined by a proven drug prevention program was associated with adolescent perceptions of effectiveness by comparing two sets of coded responses to adolescent videotaped refusal role-plays (N = 63). The original set of codes was defined by programmatic standards of refusal assertion and the…

How much of infant behaviour can be accounted for by signal-level analyses of stimuli? The current paper directly compares the moment-by-moment behaviour of 8-month-old infants in an audiovisual preferential looking task with that of several computational models that use the same video stimuli as presented to the infants. One type of model…

The effectiveness of evidence-based programs can be compromised if the program is not implemented with fidelity. This article describes the evaluation of an online training to improve implementation fidelity to an evidence-based HIV prevention curriculum, Reducing the Risk, through online skills-based instruction and support. Educators were…

English is one of the most spoken languages in the world and widely accepted as a foreign language in many parts of the world. However, though there has been a high demand for English as a foreign language in the 21st century, it has still been taught or learned through traditional methods and conventional pedagogical approaches. In the digital…

This article presents results from an empirical study of how student engagement is visible during introductory algebra. Previously, the notion of engagement in mathematics has been studied from students' and researchers' perspectives. This study is instead focused on teachers' perspectives on student engagement. Eight teachers in grade 6-7 have…

In the light of the European Union's interest in creativity and innovation, this paper, drawing on data from the EU project Creative Little Scientists (2011-2014), explores the teaching and learning of science and creativity in Early Years education. The project's conceptual framework, developed from detailed analysis of relevant literatures,…

Web-augmented traditional lecture, fully online, and flipped sections, all taught by the same instructor with the same course schedule, assignments, and exams in the same semester, were compared with regards to student attitudes; statistical reasoning; performance on common exams, homework, and projects; and perceptions of the course and…

Classroom code switching in foreign language teaching is still a controversial issue whose status as a tool of both despair and desire continues to be hotly debated. As the teaching of content and language integrated learning (CLIL) is, by definition, concerned with the learning of a foreign language, one would expect the value of code switching…

The purpose of this study was to investigate the current challenges in English language learning and teaching in Turkey from high and low achievers' perspective. The study was qualitative in nature and the participants of the study were twenty-two students attending at various departments of a state university in Turkey. In this study, the…
