Identifying Liars Through Automatic Decoding of Children's Facial Expressions

This study explored whether children's (N = 158; 4- to 9 years old) nonverbal facial expressions can be used to identify when children are being deceptive. Using a computer vision program to automatically decode children's facial expressions according to the Facial Action Coding System, this study employed machine learning to determine whether facial expressions can be used to discriminate between children who concealed breaking a toy(liars) and those who did not break a toy(nonliars). Results found that, regardless of age or history of maltreatment, children's facial expressions could accurately (73%) be distinguished between liars and nonliars. Two emotions, surprise and fear, were more strongly expressed by liars than nonliars. These findings provide evidence to support the use of automatically coded facial expressions to detect children's deception.     

A present absence: undergraduate course outlines and the development of student creativity across disciplines

While recent scholarship has suggested that colleges and universities have an obligation to help cultivate students’ creativity, existing evidence suggests that this priority is infrequently and imperfectly realized in practice. In order to further examine the potential prevalence of this gap, the present study conducted a qualitative analysis of all publicly available undergraduate course outlines from one Canadian university for the 2013–2014 academic year. Using a modified version of an existing analytical tool, we scrutinized syllabi from across academic disciplines for explicit and implicit references to student creativity, understanding these texts as significant locations at which meanings about teaching and learning are enacted. Based on this analysis, we argue that creativity occupies a relatively circumscribed position in many ways – particularly in the Science, Technology, Engineering, and Mathematics disciplines, but may nonetheless be fostered through the deployment of relevant activities. Implications for the development of student creativity are considered.     

ViLLE – collaborative education tool: Designing and utilizing an exercise-based learning environment

Automatically assessed exercises with immediate feedback can be a powerful tool for enhancing the effectiveness of education. In this article, we discuss the design and implementation of a collaborative learning tool called ViLLE. The design is based on experiences gathered from a previously developed and thoroughly researched visualization tool. Based on our earlier results and current educational theories, we developed four design principles upon which ViLLE is constructed. ViLLE includes various different exercise types which were designed to assist in the learning of computer science, mathematics and other subjects. It also supports different learning and teaching methods, such as pair programming and peer review. To justify the development of a new environment, we present four diverse case studies where ViLLE was utilized successfully: programming education, high school matriculation exam, elementary school mathematics and student counseling at university level. The results obtained from the studies seem to confirm that ViLLE can be used effectively to enhance student motivation and to improve student performance in various heterogeneous educational setups.     

Health-Seeking Preferences of Elderly Filipinos in the Community via Conjoint Analysis

Health-seeking encompasses the activities individuals perform in order to restore wellness when they perceive themselves as ill. Alarmingly, it is apparent that there is a decrease in frequency of health-seeking as one ages. While there have been numerous studies about elderly health-seeking behavior across the globe, the need to know about their preferences remains a research imperative, hence this conjoint analysis investigation. The objective of this study is to identify the health-seeking preferences of a select group of Filipino elderly in the community. To measure preferences for health-seeking, a conjoint analysis survey of 304 Filipino elderly aged 60 years and above was conducted from June to July 2012 using the balanced incomplete block design. Results indicate that the most important attribute in terms of health-seeking behavior is the physician's experience. Elderly clients tend to seek health care from expert private practitioners who provide full information regarding illness and charge professional fees of less than 500 pesos (8–9 British pounds or 12–13 U.S. dollars). Results suggest that there are factors that may impede or promote health care seeking in elderly clients, of which physicians’ experience is deemed most important. These preferences, if integrated into the current practice, can help health care practitioners in improving the quality of care provided.     

Collaboration and integration of services in Greek special schools: two different models of delivering school services

Multidisciplinary collaboration is considered to be very important for the education of pupils with special educational needs and particularly those pupils with the most severe disabilities. This research adopts a multiple case‐study design in order to understand collaboration and the integration of services and the effectiveness of these among pupils with profound and multiple learning difficulties (PMLD) in Greece. The teams, choosing case studies in five special schools, considered 10 pupils and their parents. Reviews and analyses of the legislation; the use of diaries; participant observations and semi‐structured interviews were used for the collection of data. Two different models of service integration which provide different opportunities to the inclusion of pupils with PMLD were revealed since schools have different methods of integrating health and social professionals. In the first model, the school works with outside services, whereas in the second, services are within the school. In addition, roles and responsibilities differ within the different models. Service integration and collaboration were found to be more effective in schools where teachers and health and social professionals work under the same management. The study suggests the expansion of the second model of multidisciplinary collaboration with the integration in schools of health therapists, educational psychologists and social workers.     

On study habits on an introductory course on programming

Computer aided assessment systems enable the collection of exact time and date information on students’ activity on a course. These activity patterns reflect students’ study habits and these study habits further predict students’ likelihood to pass or fail a course. By identifying such patterns, those who design the courses can enforce positive study habits and to prevent or minimize habits that lead to poor student performance. Hypothetically, by identifying and adjusting the short-term patterns, the teachers might be able to do the same during the course. This publication examines students’ short-term study habits on an introductory level programming course and presents multiple statistically significant connections between students’ assignment submission patterns and their respective final grades. Students who receive the highest grade start and finish their work early, do not work on weekends, and do not work at night, whereas those who fail the course do not show similar behavior but exhibit significant enrichment among those who work large amounts during the night. Course’s mandatory tutorial sessions that act both as assignment release events and as collaborative assignment solving sessions strongly increase assignment submission counts regardless of the students’ final grades and ensure an early start to solving the assignments, possibly preventing those who would otherwise fail the course from starting their work near deadlines.
