Traditional assessments of public speaking skills rely on human scoring. We report an initial study on the development of an automated scoring model for public speaking performances using multimodal technologies. Task design, rubric development, and human rating were conducted according to standards in educational assessment. An initial corpus of…

Large-scale audiovisual data that measure group learning are time consuming to collect and analyze. As an initial step towards scaling qualitative classroom observation, we qualitatively coded classroom video using an established coding scheme with and without its audio cues. We find that interrater reliability is as high when using visual data…

In order for a person to comprehend metaphoric expressions, do metaphor-irrelevant aspects of literal information need to be inhibited? Previous research using sentence-verification paradigms has found that literal associates take longer to process after reading metaphorical sentences; however, it is problematic to infer inhibition from this…

In argument diagrams, perceptual cues are important to aid understanding. However, we do not know what perceptual cues are used and produced to aid understanding. We present two studies in which we investigate (1) which spatial, graphical and textual elements people spontaneously use in creating for-against argument diagrams, and (2) how people…

Evidence supports the benefits of effortful processing in strengthening retention of newly learned material. The present study compared two forms of effortful processing, uncued (free) recall and cued recall, under both open and closed book conditions, on both immediate and delayed (one-week) test performance. Participants read a section of a…

Over the past few years, one of the most fundamental changes in current computer-mediated environments has been input devices, moving from mouse devices to touch interfaces. However, most studies of online retailing have not considered device environments as retail cues that could influence users' shopping behavior. In this research, I examine the…

The present study used a multiple probe across participants design to examine the effects of systematic and explicit instruction to teach students with severe disabilities (SD) to comprehend and discuss grade-aligned literature. The text was adapted and formatted as a read-aloud on an iPad2®. Using a modified system of least prompts, participants…

Self-assessment is essential to scientific literacy as stated by the National Research Council Committee on Conceptual Framework for the New K-12 Science Education Standards and has since been incorporated into the Next Generation Science Standards. However, little empirical evidence documents which instructional tools are beneficial in improving…

London dispersion forces (LDFs) are the most fundamental of the noncovalent interactions in that they are interactions that act between all molecular species and require only that students can use the "electron cloud" model of atomic structure. In this longitudinal study we investigate how students respond to prompts, designed to elicit…

This study tested 3 instructor presence features in learning from video lectures: dynamic drawings, eye contact with the camera, and instructor visibility. In 2 experiments, college students watched a video lecture about the human kidney, which consisted of a series of drawings and a spoken explanation from the instructor, and then took a written…

The purpose of this study was to investigate the characteristics of online students' cognitive presence in a peer-facilitated discussion environment, and to identify the peer facilitation techniques that can enhance cognitive presence development. In this study, 738 discussion messages were examined by both qualitative and quantitative content…

This study examines whether and how five novice history teachers incorporated writing into their instruction. We analyzed observations, student writing, teacher feedback and interviews, and classroom artifacts from teachers' preservice program experiences and first 2 years of teaching. All novices included writing in their instruction; however; we…

Objective: The purpose of this study was to determine the most suitable health messages and designs to create point-of-choice prompts for promoting active transportation and staircase use that would appeal to undergraduate students. Participants: Undergraduate students (N = 21; 71% women) were recruited during Fall (2016) and Winter (2017)…

This book demonstrates the positive impact of using film and audiovisual material in the language classroom. The chapters are evidence-based and address different levels and contexts of learning around the world. They demonstrate the benefits of using moving images and films to develop intercultural awareness and promote multilingualism, and…

This study is on the development of English vocabulary skills of selected High School and College students of Bukidnon and Cagayan De Oro City. Specifically, it sought to focus on four areas: when teachers develop vocabulary, the teaching techniques employed to develop vocabulary, students' reaction to the activities presented and the behaviors…
