Wizundry: A Cooperative Wizard of Oz Platform for Simulating Future Speech-based Interfaces with Multiple Wizards

Wizard of Oz (WoZ) as a prototyping method has been used to simulate intelligent user interfaces, particularly for speech-based systems. However, as our societies' expectations on artificial intelligence (AI) grows, the question remains whether a single Wizard is sufficient for it to simulate smarter systems and more complex interactions. Optimistic visions of 'what artificial intelligence (AI) can do' places demands on WoZ platforms to simulate smarter systems and more complex interactions. This raises the question of whether the typical approach of employing a single Wizard is sufficient. Moreover, while existing work has employed multiple Wizards in WoZ studies, a multi-Wizard approach has not been systematically studied in terms of feasibility, effectiveness, and challenges. We offer Wizundry, a real-time, web-based WoZ platform that allows multiple Wizards to collaboratively operate a speech-to-text based system remotely. We outline the design and technical specifications of our open-source platform, which we iterated over two design phases. We report on two studies in which participant-Wizards were tasked with negotiating how to cooperatively simulate an interface that can handle natural speech for dictation and text editing as well as other intelligent text processing tasks. We offer qualitative findings on the Multi-Wizard experience for Dyads and Triads of Wizards. Our findings reveal the promises and challenges of the multi-Wizard approach and open up new research questions.Comment: 34 page

The impact of feedback on students’ affective states

Affective states play a significant role in students' learning behaviour. Positive affective states can enhance learning, while negative affective states can inhibit it. This paper describes a Wizard-of-Oz study that investigates the impact of different types of feedback on students' affective states. Our results indicate the importance of providing feedback matched carefully to the affective state of the students in order to help them transition into more positive states. For example when students were confused affect boosts and specific instructive feedback seem to be effective in helping students to be in flow again. We discuss this and other ways to adapt the feedback, together with implications for the development of our system and the field in general

Light-bulb moment?: towards adaptive presentation of feedback based on students' affective state

Affective states play a significant role in students’ learning behaviour. Positive affective states can enhance learning, whilst negative affective states can inhibit it. This paper describes a Wizard-of-Oz study which investigates whether the way feedback is presented should change according to the affective state of a student, in order to encourage affect change if that state is negative. We presented high-interruptive feedback in the form of pop-up windows in which messages were immediately viewable; or low-interruptive feedback, a glow- ing light bulb which students needed to click in order to access the messages. Our results show that when students are confused or frustrated high-interruptive feedback is more effective, but when students are enjoying their activity, there is no difference. Based on the results, we present guidelines for adaptively tailoring the presentation of feedback based on students’ affective states when interacting with learning environments

Designing a toolkit to support dialogue in learning

Whilst the use of dialogue has many pedagogic advantages to offer Higher Education, implementing it effectively in teaching practice is a complex and problematic process that requires a wide range of expertise. This paper describes one strategy for addressing this issue: the development of a toolkit that supports the process of planning and reflection that practitioners must engage in when attempting to use dialogue in their teaching. After identifying and illustrating some of the issues relating to the use of dialogue, the notion of toolkits will be defined and a methodology for their development outlined. This is then exemplified with the specific case of the design of a toolkit for using dialogue in learning. A study is then described in which this prototype toolkit was evaluated, demonstrating its impact both in terms of changing practice and of developing a critical awareness of the issues relating dialogue and learning, before conclusions are drawn about the wider relevance of the work

Following the Yellow Brick Road: The Lived Journey of Nurses Becoming Nurse Practitioners

In this phenomenological study, I explore the lived experiences of registered nurses who become nurse practitioners. Text for this study comes from narrative sources such as reflective writings, one-on-one conversations, and group conversations with seven new nurse practitioners. The guiding question for this inquiry is: "What is the lived journey of nurses who become nurse practitioners?" Phenomenological philosophers such as Heidegger, Gadamer, and Casey guide this work. Other authors are drawn upon for grounding the study and to draw out the phenomenon for examination. The six research activities of van Manen (2003) provide the methodological framework for the research. The "yellow brick road" traveled by the registered nurse to nurse practitioner is the metaphor that has revealed itself as we reflect on the journey. Literature from the disciplines of nursing and education, poetry, and narrative accounts complement the stories told by nurse practitioners and open up new ways to think about the lived experience. Stories are the bricks that form the yellow road that lead us to a new way of being. Nurses who become nurse practitioners experience the journey from school to beginning practice and finally to comfort in the new place. Conversations reveal the meaning of the journey. The webs of support woven with other students are found to be very important. Before reaching the end of the road, many detours are encountered that slow, but never stop, the journey. During this journey new nurse practitioners find that the nurse part of nurse practitioner is as important as the new skills they have learned. At the end of the journey they find that the greatest source of strength is from themselves. Both teacher and students are transformed as we travel together on the path. A call is made for a revolution in nursing curriculum as narrative leads to a new way of teaching and learning. The journey reveals a new way of living curriculum and being with students as mentor and teacher

Understanding The Use Of Feature Films To Maximize Student Learning

Feature films, old and new, have been used for many years to teach management education in general and leadership skills in particular. Films are often able to affect not only our emotional responses and perceptions of events, but they can also have an impact on our personal lives over long periods of time. Although anecdotal evidence (primarily based upon Social Learning Theory) has generally supported the use of feature films to teach management education, the paper draws upon theoretical advances in universalistic self-theory as part of cognitive-experiential self-theory (CEST) as an epistemological basis for why and under what specific conditions management educators should use feature films to maximize student learning. From this reasoning, the paper proposes that management educators apply contextual self-theory as a pedagogical guide for the actual selection of films for classroom use. In addition, the paper highlights the importance of how the management educator needs to look at other factors, such as the age and cultural background of students, as important considerations for the selection and use of feature films in the classroom
