This article argues that the TENC ePortfolio definition should integrate rhetorical, pedagogical, social, and technical perspectives. The rhetorical perspective is needed to show the learner ́s competences, achievements and history; the pedagogical perspective aims at supporting learner ́s selfreflection, through the definition of competences mastered, review and creation of (new) CDPs, creation ...

While the independent contributions of synchronous and asynchronous interaction in online learning are clear, comparatively less is known about the pedagogical consequences of using both modes in the same environment. In this study, we examine relationships between students’ use of asynchronous discussion forums and synchronous private messages (PM). We find that asynchronous notes contain more...

One problem in science education is that students neither construct in-depth conceptual understanding nor are they able to analyze and apply scientific thinking processes (National Research Council, 1996). A myriad of studies on conceptual change have investigated the nature and process of conceptual change, pedagogical strategies to foster conceptual change and improve higher-level thinking. O...

According to cognitive load theorists, the incorporation of extraneous features, such as pedagogical agents, into the learning environment can introduce extraneous cognitive load and thus interfere with learning outcome scores. In this study, the influence of a pedagogical agent’s presence in an instructional video was compared to a video that did not contain a pedagogical agent. The results in...

The use of technology for instruction, and the enormous amount of information available for consumption, places a considerable burden on instructors who must learn to integrate appropriate student practices and learning assessment. The Pedagogical Workflows project is developing a novel workflow environment that supports efficient assessment of student learning through interactive generation an...

We do know that new learning material must be interactive and actively involve students in the learning process. The idea is generally good but the implementation sometimes falls behind. During the analysis of e-learning materials that are publicly available, we discovered some noticeable and subtle flaws in the materials. The contemporary design paradigm of e-learning materials requires produc...

Inspectable Bayesian student models have been used to support student reflection, knowledge awareness and communication among teacher, students and parents. This paper presents a new approach to interacting with inspectable Bayesian student models called indirectly visible Bayesian student models. In this approach, the student model is seen through the eyes of a pedagogical agent (e.g., a virtu...

This study describes the TPACK-Developing Instructional Model which prescribes an instructional process for developing pre-service teachers’ Technological Pedagogical Content Knowledge (TPACK) during the instruction of Information and Communication Technology (ICT) tools. This model proposes three phases for developing teachers’ TPACK through ICT instruction. The phases are: fostering teachers’...

As a pedagogical exercise, we derive the shape of a particularly elegant pop-up card design, and show that it connects to a classically studied plane curve that is (among other interpretations) a caustic of a circle.
