Using the Technological, Pedagogical, and Content Knowledge Framework to Design Online Learning Environments and Professional Development

In this article we sought to understand how social studies teachers metacognitive awareness of their technological, pedagogical, and content knowledge (TPACK) changed after their participation in a program that consisted of: (a) professional development for the use of an online learning environment; and (b) using an online learning environment in their classrooms. Inservice teachers who went through the TPACK-based program experienced considerable movement within the TPACK diagrammatic knowledge domains and expressed positive and encouraging comments regarding their knowledge domains portrayed within the TPACK framework. Quantitative and qualitative results are shared along with implications of designing professional development, online learning environments using TPACK, and advancing the TPACK framework itself.

An Investigation of the Use of Real-Time, Authentic Geospatial Data in the K–12 Classroom

Abstract This article situates geospatial technologies as a constructivist tool in the K-12 classroom and examines student experiences with real-time authentic geospatial data provided through a hybrid adventure learning environment. Qualitative data from seven student focus groups demonstrate the effectiveness of using real-time authentic data, peer collaboration, and geospatial technologies in learning geography. We conclude with recommendations about geospatial technology curricula, geospatial lesson design, providing preservice teachers with geographic technological pedagogical content knowledge, and encouraging further research to investigate the impact, affordances, and pedagogical implications of geospatial technologies and data in the K–12 classroom.

Conversing with pedagogical agents: A phenomenological exploration of interacting with digital entities

In this paper, we examine the meaning of conversing with pedagogical agents. Previous research has focused on examining cause and effect relationships, failing to take into account the meaning of the experiences individuals have when holding a dialogue with conversational agents for educational purposes. To understand these experiences, we have conducted a phenomenological examination of what it means to converse with a pedagogical agent. In phenomenological terms, findings suggest the experience is complex, engrossing, virtual yet real, human-like, and social. Implications for the future design, implementation, and research of conversational agents in educational and other settings are discussed. [ABSTRACT FROM AUTHOR]

Hybrid Online Education: Identifying Integration Models Using Adventure Learning

Abstract In this paper we sought to understand how teachers chose to integrate a hybrid online education program in their classrooms, how students responded to this choice, and how students’ experiences were influenced by the integration model chosen by the teachers. Data collected via classroom observations, personal interviews, and focus groups suggest four integration models: curriculum-based, activities-based, standards-based, and media-based. We discuss these models in the context of hybrid online education and particularly in adventure learning. Finally, we provide recommendations for the design, development, implementation, and integration of hybrid online education programs.

Cognitive and Affective Benefits of an Animated Pedagogical Agent: Considering Contextual Relevance and Aesthetics

Choi and Clark (2006) argue that learning is attributed to the instructional method rather than the specific medium used to deliver instruction (i.e., the pedagogical agent). Additionally, they consider pedagogical agents as unnecessarily expensive tools, whose instructional affordances can be replicated by less expensive options. In this response to Choi and Clark (2006), I argue that pedagogical agents are not a new iteration of the media debate because the anthropomorphous features and social affordances of pedagogical agents elicit psychological responses from learners that other media cannot educe. As such, when considering the implementation of pedagogical agents, researchers need to consider the agents (a) contextual relevance, and (b) aesthetic properties. It is important to note that none of these factors influence the instructional method used to deliver instruction via a pedagogical agent.

The effects of digital video quality on learner comprehension in an American sign language assessment environment

The effects of digital video frame rate and size on American Sign Language (ASL) learner comprehension were investigated. Fifty-one students were randomly assigned to one of three video-size treatment groups: 480×360, 320×240, and 240×180 pixels. Within each treatment, three 30-second videos of signed narratives at frame rates of 6, 12, and 18 frames per second were presented to students. Participants used ASL to retell each story, while a digital video camera captured their performances and archived them for evaluation. Three ASL experts evaluated the video performances and generated a fluency score for each student. The results indicate that frame rate and the interaction between frame rate and ASL level had significant effects on learner comprehension, but video size did not significantly affect comprehension. These results were used to generate frame rate and video-size recommendations for displaying and recording student performance and instructor feedback videos in an ASL performance assessment software environment.

The Impact and Implications of Virtual Character Expressiveness on Learning and Agent-Learner Interactions.

The possible benefits of agent expressiveness have been highlighted in previous literature; yet, the issue of verbal expressiveness has been left unexplored. I hypothesize that agent verbal expressiveness may improve the interaction between pedagogical agents and learners, ultimately enhancing learning outcomes. Evidence from a quasi-experimental investigation, indicates that learners who interacted with an expressive agent 1) scored higher on a post-task exam; and 2) rated the agents ability to interact higher, than learners who interacted with a non-expressive agent. Qualitative results provided insight into this finding, while indicating the complexity of deploying pedagogical agents in educational settings.

When sex, drugs, and violence enter the classroom: Conversations between adolescents and a female pedagogical agent

In this article, we investigate the discourse between a female conversational pedagogical agent and 59 adolescents in the context of a social studies lesson. We note that previous pedagogical agent research has focused on the positive effects of agents, while failing to take into account the intricacies of learner-agent discourse, and subsequently missing the abuse suffered by pedagogical agents at users fingertips. Our analysis indicates that learners readily misuse and abuse pedagogical agents while placing them in a subordinate and inferior role. We conclude by making recommendations on agent design and future research.

Enali: A Research and Design Framework for Virtual Characters and Pedagogical Agents

Conflicts occur when learners interact with pedagogical agents and virtual characters. Such conflicts—arising from technological limitations, psychosocial perceptions, and pedagogical inadequacies—hinder communication and interaction between virtual characters and learners, and impede successful engagement with learning tasks and experiences. To enhance communication and interaction between virtual characters and learners, we propose a three-tier framework of 15 research-based guidelines. This framework enables theorists, researchers, and designers to view virtual characters with a holistic lens, informing the analysis, design, development, implementation, and evaluation of virtual characters in electronic learning contexts.

Curriculum at forty below: a phenomenological inquiry of an educator/explorer’s experience with adventure learning in the Arctic

Grounded in the theoretical approaches of experiential learning and inquiry‐based learning, adventure learning (AL) is a hybrid distance education approach that seeks to transform the experiences of students by having learners explore real‐world issues and pursue answers to their own questions in an authentic, anchor‐based environment. In this article we present a theoretical overview of AL, provide a brief summary of recently examined AL impacts in the classroom, and use a phenomenological lens to examine the experience of an educator/explorer who traveled by dogsled over 3000 miles across the Arctic to engage students and teachers from around the world in a truly authentic learning context. We conclude by offering recommendations for teachers who wish to embark on their own unique AL experiences with their students (without necessarily having to travel to the Arctic).
