Discriminating Cognitive Disequilibrium and Flow in Problem Solving: A Semi-Supervised Approach Using Involuntary Dynamic Behavioral Signals

Problem solving is one of the most important 21st century skills. However, effectively coaching young students in problem solving is challenging because teachers must continuously monitor their cognitive and affective states, and make real-time pedagogical interventions to maximize their learning outcomes. It is an even more challenging task in social environments with limited human coaching resources. To lessen the cognitive load on a teacher and enable affect-sensitive intelligent tutoring, many researchers have investigated automated cognitive and affective detection methods. However, most of the studies use culturally-sensitive indices of affect that are prone to social editing such as facial expressions, and only few studies have explored involuntary dynamic behavioral signals such as gross body movements. In addition, most current methods rely on expensive labelled data from trained annotators for supervised learning. In this paper, we explore a semi-supervised learning framework that can learn low-dimensional representations of involuntary dynamic behavioral signals (mainly gross-body movements) from a modest number of short time series segments. Experiments on a real-world dataset reveal a significant advantage of these representations in discriminating cognitive disequilibrium and flow, as compared to traditional complexity measures from dynamical systems literature, and demonstrate their potential in transferring learned models to previously unseen subjects.

Putting the Patient Back in Patient Care: Health Decision-Making from the Patient’s Perspective

This research explored health decision-making processes among people recently diagnosed with type 2 diabetes. Our analysis suggested that diagnosis with type 2 was followed by a period of intense emotional and cognitive disequilibrium. Subsequently, the informants were observed to proceed to health decision-making which was affected by three separate and interrelated factors: knowledge, self-efficacy, and purpose. Knowledge included cognitive or factual components and emotional elements. Knowledge influenced the degree of upset or disequilibrium the patient experienced, and affected a second category, agency: the informants’ confidence in their ability to enact lifestyle changes. The third factor, purpose, summarized the personal and deeply held reasons people gave as they made decisions concerning their health, eating and exercising. We propose this model, grounded in informant stories, as a heuristic, to guide further inquiry. From these stories, the patient is seen as more active and the interrelated influences of knowledge, agency, and purpose, synergistically interact to explain changes in health behaviors.

Cognitive Disequilibrium and Service-Learning in Physical Education Teacher Education: Perceptions of Pre-Service Teachers in a Study Abroad Experience

Purpose:The purpose of this study was to explore preservice teachers’ experiences of cognitive disequilibrium (CD) theory during a service-learning project in a study abroad experience.Method:A case study with 8 participants was used. Data sources consisted of: Formal interviews, videos of planning, videos of teaching, videos of reflection sessions, and informal interviews. Data were analyzed utilizing open and axial coding (Corbin & Strauss, 2008). Trustworthiness strategies included: prolonged engagement, multiple data source triangulation, and member checks.Results:Results indicated four themes: “We made it our own thing”, “Summer camp for teachers”, “Struggle and disequilibrium”, and “By the end it was a transformation”.Discussion/Conclusions:CD was ultimately positive for these students. The positive resolution of CD catalyzed a transformative effect on their perceptions of their teaching. This was supported by positive peer interaction.

Moral Development in Christian Higher Education

Recent research concerning the mural development of evangelical college and seminary students utilizing Kohlberg's stage theory was examined. Biblical parallels to moral development theory were noted and briefly explored. Various explanations for evangelical students' lower than expected scores on moral development tests were considered including such factors as lack of reflection regarding the content of the faith as well as application of biblical principles, weaknesses in the evangelical educational process including the absence of cognitive disequilibrium, evangelical orientation toward biblical care and concern as well as toward justice, and the manner in which an institution's standards of conduct are communicated to students.
