The feasibility of capturing learner interactions based on logs informed by eye-tracking and remote observation studies

Two small studies, one an eye-tracking study and the other a remote observation study, have been conducted to investigate ways to identify two kinds of online learner interactions: users flicking through the web pages in "browsing" action, and users engaging with the content of a page in "learning" action. The video data from four participants of the two small studies using the OpenLearn open educational resource materials offers some evidence for differentiating between 'browsing' and 'learning'. Further analysis of the data has considered possible ways of identifying similar browsing and learning actions based on automatic user logs. This research provides a specification for researching the pedagogical value of capturing and transforming logs of user interactions into external forms of representations. The paper examines the feasibility and challenge of capturing learner interactions giving examples of external representations such as sequence flow charts, timelines, and table of logs. The objective users information these represent offer potential for understanding user interactions both to aid design and improve feedback means that they should be given greater consideration alongside other more subjective ways to research user experience

Three essays on the political economy of forensic science

This dissertation is a collection of three essays which explores how public choice and public finance issues affect the provision and production of local public goods. This dissertation looks specifically at the provision of forensic science services. Chapter 2 explores the methodology in measuring how public or private a good is, and finds that ignoring the zoo effect can cause upward bias in the measurement of how private a good is. Chapter 3 estimates the cost differences between nationally and locally operated forensic science laboratories, and using an average total cost function, determines that nationally operated laboratories are not more or less efficient than sub-national laboratories. Finally, chapter 4 explores the Leviathan model, and finds that governments can, and in the case of the Deficit Reduction Act of 1984 do, operate in ways that reduce tax revenues

Crew Resource Management and Its Possible Role in Nursing Risk Management

Crew Resource Management (CRM) was introduced within the aviation industry in the late 1970s after an aircraft ran out of fuel whilst the pilots were trying to solve an undercarriage problem. To reduce such errors and ultimately lower the probability of failure and the severity of risks that occur, training in CRM was rolled out across the whole industry. It has been successful over the last few years in major reductions in the number of crashes and fatalities in the commercial aviation sector. Nursing has similar concerns in that errors can ultimately result in fatalities. There are parallels in the needs and expectations of pilots and nurses to assess risk, reduce risk and deliver reliable and dependable professional services. In this paper the parallels of pilots and nurses demands are compared to assess if the lessons learned in aviation can assist nurses deliver procedures with lower risks. The analysis will draw on the demands and expectations and how they both deal with risk, challenging errors and ensuring that identified risks are not overlooked or ignored. Finally, suggestions of adopting, sharing and benchmarking between these two industries can adopt best practices so that both industries can learn from each other

Social Media in the Dental School Environment, Part A: Benefits, Challenges, and Recommendations for Use

Social media consist of powerful tools that impact not only communication but relationships among people, thus posing an inherent challenge to the traditional standards of who we are as dental educators and what we can expect of each other. This article examines how the world of social media has changed dental education. Its goal is to outline the complex issues that social media use presents for academic dental institutions and to examine these issues from personal, professional, and legal perspectives. After providing an update on social media, the article considers the advantages and risks associated with the use of social media at the interpersonal, professional, and institutional levels. Policies and legal issues of which academic dental institutions need to be aware from a compliance perspective are examined, along with considerations and resources needed to develop effective social media policies. The challenge facing dental educators is how to capitalize on the benefits that social media offer, while minimizing risks and complying with the various forms of legal constraint

Social Media in the Dental School Environment, Part B: Curricular Considerations

The goal of this article is to describe the broad curricular constructs surrounding teaching and learning about social media in dental education. This analysis takes into account timing, development, and assessment of the knowledge, skills, attitudes, and behaviors needed to effectively use social media tools as a contemporary dentist. Three developmental stages in a student’s path to becoming a competent professional are described: from undergraduate to dental student, from the classroom and preclinical simulation laboratory to the clinical setting, and from dental student to licensed practitioner. Considerations for developing the dental curriculum and suggestions for effective instruction at each stage are offered. In all three stages in the future dentist’s evolution, faculty members need to educate students about appropriate professional uses of social media. Faculty members should provide instruction on the beneficial aspects of this communication medium and help students recognize the potential pitfalls associated with its use. The authors provide guidelines for customizing instruction to complement each stage of development, recognizing that careful timing is not only important for optimal learning but can prevent inappropriate use of social media as students are introduced to novel situations
