A gentle transition from Java programming to Web Services using XML-RPC

Exposing students to leading edge vocational areas of relevance such as Web Services can be difficult. We show a lightweight approach by embedding a key component of Web Services within a Level 3 BSc module in Distributed Computing. We present a ready to use collection of lecture slides and student activities based on XML-RPC. In addition we show that this material addresses the central topics in the context of web services as identified by Draganova (2003)

Introductory programming: a systematic literature review

As computing becomes a mainstream discipline embedded in the school curriculum and acts as an enabler for an increasing range of academic disciplines in higher education, the literature on introductory programming is growing. Although there have been several reviews that focus on specific aspects of introductory programming, there has been no broad overview of the literature exploring recent trends across the breadth of introductory programming. This paper is the report of an ITiCSE working group that conducted a systematic review in order to gain an overview of the introductory programming literature. Partitioning the literature into papers addressing the student, teaching, the curriculum, and assessment, we explore trends, highlight advances in knowledge over the past 15 years, and indicate possible directions for future research

Four approaches to teaching programming

Based on a survey of literature, four different approaches to teaching introductory programming are identified and described. Examples of the practice of each approach are identified representing procedural, visual, and object-oriented programming language paradigms. Each approach is then further analysed, identifying advantages and disadvantages for the student and the teacher. The first approach, code analysis, is analogous to reading before writing, that is, recognising the parts and what they mean. It requires learners to analyse and understand existing code prior to producing their own. An alternative is the building blocks approach, analogous to learning vocabulary, nouns and verbs, before constructing sentences. A third approach is identified as simple units in which learners master solutions to small problems before applying the learned logic to more complex problems. The final approach, full systems, is analogous to learning a foreign language by immersion whereby learners design a solution to a non-trivial problem and the programming concepts and language constructs are introduced only when the solution to the problem requires their application. The conclusion asserts that competency in programming cannot be achieved without mastering each of the approaches, at least to some extent. Use of the approaches in combination could provide novice programmers with the opportunities to acquire a full range of knowledge, understanding, and skills. Several orders for presenting the approaches in the classroom are proposed and analysed reflecting the needs of the learners and teachers. Further research is needed to better understand these and other approaches to teaching programming, not in terms of learner outcomes, but in terms of teachers’ actions and techniques employed to facilitate the construction of new knowledge by the learners. Effective classroom teaching practices could be informed by further investigations into the effect on progression of different toolset choices and combinations of teaching approache

Group project work from the outset: an in-depth teaching experience report

This article is an extended version of a paper that was submitted to 24th IEEE Conference on Software Engineering Education and Training, Honolulu, May 2011CONTEXT - we redesigned our undergraduate computing programmes to address problems of motivation and outdated content. METHOD - the primary vehicle for the new curriculum was the group project which formed a central spine for the entire degree right from the first year. RESULTS - so far this programme has been successfully run once. Failures, drop outs and students required to retake modules have been halved (from an average of 21.6% from the previous 4 years to 9.5%) and students obtaining the top two grades have increased from 25.2% to 38.9%. CONCLUSIONS - whilst we cannot be certain that all improvement is due to the group projects informally the change has been well received, however, we are looking for areas to improve including the possibility of more structured support for student metacognitive awareness

A report on e-portfolios : design features, uses, benefits, examples & emerging trends

This paper gives a more sophisticated response to the rapid (re)emergence of the e­portfolio buzz­word. Starting from a basic e­portfolio design pattern, a wide range of variations are explored. The aim is to establish a body of knowledge for guiding users and technology providers, so as to achieve an ever­more appropriate and fruitful alignment of needs, designs, platforms and informed choices. The key benefits of e­portfolio approaches are discussed, with some coverage of the variations, and suggested research and development directions. Deep and persistent diversity­creating factors are highlighted. A range of mini case studies from Warwick are then examined to throw further light upon the combinations of real and perceived needs, platform affordances and design choices. Finally, this is a fast evolving field, especially given the near ­ubiquitous adoption of platforms with e­portfolio­like elements (Facebook, LinkedIn etc). Technology and academic support services must look further forwards to emerging practices and requirements just at the edge of the institutional­perceptual horizon. We must be prepared to shape these potentially disruptive developments for the benefit of students, teachers, the institution and society

Understanding Teacher Sense-Making Discourse During Collaborative Professional Development of an Expansively-Framed Computer Science Curriculum

Elementary school teachers are being increasingly asked to teach computer science—something that most teacher certification programs do not prepare them for. In an attempt to study how elementary teachers learn to teach computer science, I analyzed the ways that teachers behaved during a professional development accompanying the implementation of a fifth-grade computer science curriculum. My findings suggest that teachers benefit from professional development that encourages collaboration and active participation in teachers through discussion and modeling. Furthermore, my findings suggest that teachers benefit from using curriculum that deliberately connects new concepts to content that they are already familiar and comfortable with—a model known as expansive framing. By encouraging active teacher participation in professional development and by using curriculum that relates to teachers’ existing content knowledge, we may be able to help elementary teachers prepare to teach computer science with more confidence and accuracy

Research and Education in Computational Science and Engineering

Over the past two decades the field of computational science and engineering (CSE) has penetrated both basic and applied research in academia, industry, and laboratories to advance discovery, optimize systems, support decision-makers, and educate the scientific and engineering workforce. Informed by centuries of theory and experiment, CSE performs computational experiments to answer questions that neither theory nor experiment alone is equipped to answer. CSE provides scientists and engineers of all persuasions with algorithmic inventions and software systems that transcend disciplines and scales. Carried on a wave of digital technology, CSE brings the power of parallelism to bear on troves of data. Mathematics-based advanced computing has become a prevalent means of discovery and innovation in essentially all areas of science, engineering, technology, and society; and the CSE community is at the core of this transformation. However, a combination of disruptive developments---including the architectural complexity of extreme-scale computing, the data revolution that engulfs the planet, and the specialization required to follow the applications to new frontiers---is redefining the scope and reach of the CSE endeavor. This report describes the rapid expansion of CSE and the challenges to sustaining its bold advances. The report also presents strategies and directions for CSE research and education for the next decade.Comment: Major revision, to appear in SIAM Revie
