Bayesian networks and decision trees in the diagnosis of female urinary incontinence

This study compares the effectiveness of Bayesian networks versus Decision Trees in modeling the Integral Theory of Female Urinary Incontinence diagnostic algorithm. Bayesian networks and Decision Trees were developed and trained using data from 58 adult women presenting with urinary incontinence symptoms. A Bayesian Network was developed in collaboration with an expert specialist who regularly utilizes a non-automated diagnostic algorithm in clinical practice. The original Bayesian network was later refined using a more connected approach. Diagnoses determined from all automated approaches were compared with the diagnoses of a single human expert. In most cases, Bayesian networks were found to be at least as accurate as the Decision Tree approach. The refined Connected Bayesian Network was found to be more accurate than the Original Bayesian Network accurately discriminated between diagnoses despite the small sample size. In contrast, the Connected and Decision Tree approaches were less able to discriminate between diagnoses. The Original Bayesian Network was found to provide an excellent basis for graphically communicating the correlation between symptoms and laxity defects in a given anatomical zone. Performance measures in both networks indicate that Bayesian networks could provide a potentially useful tool in the management of female pelvic floor dysfunction. Before the technique can be utilized in practice, well-established learning algorithms should be applied to improve network structure. A larger training data set should also improve network accuracy, sensitivity, and specificity

Developing a Moderation Community of Practice

This paper reports on a study to evaluate technology-based processes for assessment moderation.The aim was to evaluate standard features found in an institutional Learning Management System,and their compatibility with the values and practices of a large teaching team. The process used anonline discussion board forum for tutors, the paring of more experienced tutors with those new tothe process, and further meetings conducted in both face-to-face and web conferencingenvironments. Online rubrics were used for assessing student work and the provision of feedback.A focus group conducted after marking was concluded and the analysis of the discussion boardforum demonstrated a strong community of practice with a shared understanding of assessmentrequirements

The Skills Framework for the Information Age: Engaging Stakeholders in ICT Curriculum Design

This paper reports on a research project, examining the role of the Skills Framework for the Information Age (SFIA) in Information and Communications Technology (ICT) curriculum design and management. A goal was to investigate how SFIA informs a top-down approach to curriculum design, beginning with a set of skills that define a particular career role. A further goal was to evaluate the extent to which SFIA facilitates stakeholder interaction, such that academic programs can better identify industry needs while preparing graduates for the intended career role. The paper also evaluates the extent to which SFIA informs the identification of authentic forms of assessment and the skills and levels of autonomy and responsibility required by entry-level and Masters graduate ICT positions. Processes and practices for ICT curriculum design and management are recommended based on findings arising from this research. Although this research was conducted in an Australian context, findings suggest that there is value in using SFIA for ICT curriculum design and management, even in those jurisdictions where it is not required for accreditation or professional certification purposes

Checklist based reading's influence on a developer's understanding

This paper addresses the influence the Checklist Based Reading inspection technique has on a developer's ability to modify inspected code. Traditionally, inspections have been used to detect defects within the development life cycle. This research identified a correlation between the number of defects detected and the successful code extensions for new functionality unrelated to the defects. Participants reported that having completed a checklist inspection, modifying the code was easier because the inspection had given them an understanding of the code that would not have existed otherwise. The results also showed a significant difference in how developers systematically modified code after completing a checklist inspection when compared to those who had not performed a checklist inspection. This study has shown that applying software inspections for purposesother than defect detection include software understanding and comprehension

Evaluating software inspection cognition levels using Blooms Taxonomy

This paper reports on results from a pilot study that used Bloom's Taxonomy to observe cognition levels during software inspections conducted by undergraduate computer science and software engineering students. Cognition levels associated with three different code inspection techniques were investigated. These were the Ad hoc, Abstraction Driven, and Checklist-based reading strategies. Higher cognition levels were observed when using inspection techniques that utilise a more structured reading process. This result highlights the importance of introducing novice programmers to structured code reading strategies. Findings suggest that teaching different software inspection techniques throughout software courses, beginning with structured techniques, is an excellent way to build a student's critical software reading and analysis skills

The significance of participant experience when evaluating software inspection techniques

Software inspections have been used to improve software quality for 30 years. The Checklist Based Reading strategy has traditionally been the most prevalent reading strategy. Increased Object Oriented usage has raised questions regarding this techniques efficacy, given issues such as delocalisation. This study compared two inspection techniques: Use-Case Reading and Usage-Based Reading, with Checklist Based Reading. Students and industry professionals were recruited to participate in the study. The effectiveness of each reading strategy was analysed, and the effect experience had on inspection efficacy. The results showed no significant difference between inspection techniques,whether used by student or professional developers but a significant difference was identified between student and professional developers in applying the different techniques. Qualitative results highlighted the differences in ability between industry and students with respect to what each group considered important when inspecting and writing code. These results highlight the differences between student and industry professionals when applying inspections. Therefore, when selecting participants for empirical software engineering studies, participant experience level must be accounted for within the reporting of results

Assessing professional skills in engineering education

This paper addresses the issue of developing and assessing professional skills in higher education programs. This includes defining and assessing these skills, in the contexts of an individual course unit and for an entire degree program. Identifying forms of assessment that are seen as authentic, meaningful and understandable by the students, teaching staff and curriculum developers are of utmost importance if professional skills are to be accepted and included in the formal curriculum. This can be particularly important in programs that aim to offer students a truly collaborative learning experience in a culturally diverse team. Reflections are presented as one example of an assessment method that fits this requirement. Building assessment based on the notion of threshold concepts is introduced in the context of an open ended group project course unit at Uppsala University

Mapping a sequence diagram to the related code: cognitive levels expressed by developers

This paper reports on a study in which developers? cognitive levels were categorised and measured while theymapped a sequence diagram to the related code based on a Usage Based Reading scenario. Results indicate that applying the usage-based reading technique to map a sequence diagram to the underlying code, facilitates a developer to operate at the Knowledge and Comprehension levels of Bloom?s cognitive taxonomy, but does not facilitate sustaining it at the Analysis level. The results of this study highlight the need for improved tools and methodologies that aid developers understanding of the system, particularly for those commencing a new project

Transforming higher education and student engagement through collaborative review to inform educational design

This paper reports on staff perceptions arising from a review process designed to assist staff in making informed decisions regarding educational design, approaches to engage students in learning, and the technology to support engagement in the classroom and across multiple locations and delivery modes. The aim of the review process was to transform the level of student engagement in the business faculty of an Australian university. The process took a collaborative approach through consultation with academic staff involved in the design and delivery of the units under review, and included targeted professional development as necessary. An institutional framework that characterises engagement indicator contexts and their attributes facilitated dialog during the review process. This paper reports on a mixed method study that included a survey of participants, and purposeful interviews to evaluate the effectiveness of the process. Although the study identified factors that hindered implementation and operationalization of review recommendations in some instances, study participants were generally of the view that recommendations would enhance student engagement. It is demonstrated that the bottom-up approach described in this paper is consistent with theoretical frameworks for transformational change in teaching and learning and the adoption of innovations
