Husserl on Hallucination: A Conjunctive Reading

Several commentators have recently attributed conflicting accounts of the relation between veridical perceptual experience and hallucination to Husserl. Some say he is a proponent of the conjunctive view that the two kinds of experience are fundamentally the same. Others deny this and purport to find in Husserl distinct and non-overlapping accounts of their fundamental natures, thus committing him to a disjunctive view. My goal is to set the record straight. Having briefly laid out the problem under discussion and the terms of the debate, I then review the proposals that have been advanced, disposing of some and marking others for further consideration. A.D. Smith’s disjunctive reading is among the latter. I discuss it at length, arguing that Smith fails to show that Husserl’s views on perceptual experience entail a form of disjunctivism. Following that critical discussion, I present a case for a conjunctive reading of Husserl’s account of perceptual experience

Daubert’s Naïve Realist Challenge to Husserl

Despite extensive discussion of naïve realism in the wider philosophical literature, those influenced by the phenomenological movement who work in the philosophy of perception have hardly weighed in on the matter. It is thus interesting to discover that Edmund Husserl’s close philosophical interlocutor and friend, the early twentieth-century phenomenologist Johannes Daubert, held the naive realist view. This article presents Daubert’s views on the fundamental nature of perceptual experience and shows how they differ radically from those of Husserl’s. The author argues, in conclusion, that Daubert’s views are superior to those of Husserl’s specifically in the way that they deal with the phenomenon of perceptual constancy

A Framework for Adaptive Learning Design in a Web-Conferencing Environment

Many recent technologies provide the ability to dynamically adjust the interface depending on the emerging cognitive and collaborative needs of the learning episode. This means that educators can adaptively re-design the learning environment during the lesson, rather than purely relying on pre-emptive learning design thinking. Based on a three-semester design-based research study this paper explores how adaptive learning design can be used to provide learning environments that enable more effective collaboration and representation of information. The analysis culminates in a framework for adaptive learning design of a web-conferencing environment that depends on the type of knowledge being represented and the nature of interaction anticipated. Heuristics for adaptive learning design in synchronous multimodal environments are presented, and the potential role of students as co-designers is also discussed

The Effect Over Time of a Video-Based Reflection System on Preservice Teachers’ Oral Presentations

We report the development of preservice teachers’ oral presentation performance based on a technology-mediated Video Reflection system. Participants video-recorded oral presentations and uploaded them to an online blog to view and reflect on their performance and that of their peers. Four presentations by forty-one participants were analysed using a range of criteria based on what we call the Modes of Communication (voice, body-language, words and alignment between them) and the Constructed Impression of the communication acts (confidence, clarity, engagement and appropriateness). Results indicate a significant improvement across all criteria with a decreased rate of improvement for later iterations

Assessing Preservice Teachers’ Presentation Capabilities: Contrasting the Modes of Communication with the Constructed Impression

A research-based understanding of how to develop and assess classroom presentation skills is vital for the effective development of pre-service teacher communication capabilities. This paper identifies and compares two different models of assessing pre-service teachers’ presentation performance – one based on the Modes of Communication (voice, body language, words, and alignment between those elements) and another based on features of the Constructed Impression of the communication acts (confidence, clarity, engagement and appropriateness). The Modes of Communication and the Constructed Impression of 164 pre-service teacher presentations were rated. The Constructed Impression model provided a better fit to data, while averaging of Modes of Communication elements offered more accurate prediction of overall score. All elements in both models made a significant contribution to the overall perception of communication performance. The study also reports on the relative contribution of voice, body language, words and alignment to the perceived confidence, clarity, engagement and appropriateness of the pre-service teacher presentations. Implications for developing pre-service teachers’ presentation capabilities are also discussed
