Avoiding Object Misconceptions

This paper identifies and describes a number of misconceptions observed in students learning about object technology, It identifies simple, concrete, measures course designers and teachers can take to avoid these misconceptions arising. The context for this work centres on an introductory undergraduate course and a postgraduate course, Both these courses are taught by distance education. These courses both use Smalltalk as an introduction to object technology. More particularly, the undergraduate course uses Smalltalk as a first programming language. Distance education can limit the amount and speed of individual feedback that can be given in the early stages of learning. For this reason, particular attention has been paid to characterizing measures for avoiding elementary misconceptions seen in beginning learners. At the same time we also address some misconceptions observed in postgraduate students. The pedagogical issues discussed are of particular importance when devising an extended series of examples for teaching or assessment, or when designing a visual microworld to be used for teaching purposes

Metonymy and Student Programming Errors

The common occurrence of metonymy in everyday language is considered as a negative bias towards successfully learning to state the correct referent when learning to program. Reported errors from previous studies are surveyed and the analysis reveals a pattern consistent with the use of metonymy, a rhetorical device where the speaker states a referent that is structurally related to the intended referent. This analysis suggests an underlying cause for a class of programming errors and provides directions for further research and instructional interventions

Student success model in programming course: A case study in UUM

The complexity and difficulty ascribed to computer programming has been asserted to be the causes of its high rate of failure record and attrition. It is opined that programming either to novice, middle learner, and the self-branded geeks is always a course to be apprehensive of different studies with varying findings. Studies on factors leading to the success of programming course in higher institution have been carried out. The record at Universiti Utara Malaysia (UUM) shows that 38% of semester one undergraduate students failed the programming course in 2013. This really motivates this study, which aims at investigating the practical factors affecting the success of programming courses, and to position its’ theoretically findings to complement the existing findings. Data were gathered using a quantitative approach, in which a set of questionnaire were distributed to 282 sampled respondents, who are undergraduate and postgraduate students of Information Technology (IT) and Information and Communication Technology (ICT). Having screened and cleaned the data, which led to the deletion of four outlier records, independent T-test, correlation, and regression were run to test the hypotheses. The results of Pearson correlation test reveal that teaching tools, OOP concepts, motivation, course evaluation, and mathematical aptitude are positively related to academic success in programming course, while fear is found to be negatively related. In addition, the regression analysis explains that all the elicited independent variables except fear are strongly related. Besides, the independent T-test also discovers no deference between groups with and without previous programming experience

Separable User Interface Architectures in Teaching Object Technology

This paper concerns the critical role of separable user interface design in teaching object-oriented systems. M206 "Computing: An Object-oriented Approach" is a large-scale university-level introduction to software development designed from scratch for distance learning, using an objects-first approach with Smalltalk. The course is degree-level, counting as one sixth, and is being offered in the UK, Western Europe and Singapore. To address the needs of industry we have developed a radical syllabus that adheres to the principle of designing complex systems by separating view and model, and have developed a programming and learning environment to support these ideas. In the paper we examine how separable user interface architectures have guided our teaching of object technology and the design of powerful microworlds that are both usable and extendible by neophytes. The course and relevant teaching with software is outlined and the technical design and pedagogic use of the microworlds and GUI builder tool are described

Exploring Network Security Educator Knowledge

It is critical for nations to have trained professionals in network security who can safeguard hardware, information systems, and electronic data. Network security education is a key knowledge unit of the National Centers of Academic Excellence in Cybersecurity and various information systems security curricula at the master\u27s and bachelor\u27s levels in higher education. Network security units are components of computer science curricula in high school contexts as well. Educators who teach these concepts play a significant role in developing a skilled workforce of network security experts for both governmental and non-governmental organizations. Understanding the necessary knowledge and skills of network security educators serve to better inform institutes of higher education, educator preparation programs, and others who support educators in the field. This study describes knowledge constructs of a higher education faculty member who teaches networking and network security and was developing, and piloting innovative network security curriculum embedded in both undergraduate and graduate courses. Data were transcripts of recorded monthly meetings with the educator, fieldnotes taken during the meetings, and course artifacts. Existing teacher knowledge frameworks that have been applied in both K-12 and higher education contexts were used to deductively code the data. Examples of curricular knowledge and pedagogical content knowledge specific to the teaching of network security are provided. The affordances of using engagement within curriculum development to understand educator knowledge constructs and the existing teacher knowledge frameworks as tools for analyses are highlighted

Employing Object Technology to Expose Fundamental Object Concepts

We explore technical issues in the design of programming tools, development environments, simulations, code examples, user interface frameworks and pedagogies for a university-level course on object-oriented software development. The course, M206 Computing: An Object-Oriented Approach has been specifically developed for distance learning, and is enrolling over 5,000 students per year (average age 37) in the UK, Europe and Singapore. The course introduces computing via an object-oriented approach. M206 is substantial in extent representing one sixth of a degree. It embodies a practical, industry oriented view of computing and includes programming, analysis, design and group working. Considerable effort has been invested in making the simplicity, consistency and power of object technology accessible to and capable of being applied by beginners. A diverse set of educational media, such as CD-ROMs, TV and the Web, have been deployed as learning resources. We describe the agenda for the course; its object-oriented pedagogy and our strategy for delivery. We explain measures taken to avoid misconceptions about objects, our analysis and design method, and the Smalltalk programming environment we have developed specifically for learners and which is crucial to our approach. We outline how our adherence to the separation of view and domain model leads to technical innovations. Concluding remarks reflect on the benefits a reflexive strategy, both in education and training
