Contests are usually applied in the academic environment to simulate real professional situations that require from the participants a more pro-active attitude than the one shown in conventional coursework. Although they are commonly applied in the scope of a unique course, the contest described here was an extracurricular experience applied in an Information System undergraduate program. The evaluation of the contest is also presented; the objective was to assess the role of the contest as a tool to bring together interdisciplinary subjects, complementary to the traditional disciplinary structure of the program curriculum. The results indicate that a significant portion of the participants noticed increase in their knowledge after the contest, which is verified by statistical tests. However, students from the first stages received more benefits, probably because such students were more motivated and had more available time to be involved in the contest activities.
Distance, e-education supported by technological development have enhanced educational processes by combining achievements from various scientific fields. This techno-educational enhancement has happened within the last decade. Virtual learning has grown in popularity as a new way of learning that gives preference to learn in convenient time and places, using specially prepared learning materials. The progression of technological developments implies the rise of user demands. It also aspires to look for flexible, but qualitative, training and learning ways. One of the outcomes is adaptive and intelligent learning environments that show to become a common tool used for virtual learning.
This paper focuses on the key feature elements of adaptive learning environments (ALE), also researching about intelligent agents and their behaviour in ALEs. The method to provide individual learning syllabus according student knowledge in rational way is proposed. It is based on latent semantic indexing algorithm and is featured with an ability to update syllabus according individual learning outcomes of the student. This is yet another tool in a teacher's tool box. The description of results obtained during the exploration of proposed method is presented as well.
This paper explores our experiences in deploying a video application tool in film studies, and its evaluation in terms of realistic contextual end-users who have real tasks to perform in a real environment. We demonstrate our experiences and core lesson learnt in deploying our novel movie browser application with undergraduate and graduate students completing a Film Studies course in Dublin City University over a semester. We developed a system called MOVIEBROWSER2 that has two types of browsing modes: Advanced and Basic. In general, students found that the features we provided were beneficial for their studies. Some issues or mismatches arose during the trial. A `wish-list' was drawn up that might be useful for the future system developer. The contribution and achievements reported in this article are on the demonstration and exploration of how advances in technology can be deployed, and media can be accessed in the context of a real user community. Exploring the usage indicates a positive acceptance among students, besides lessons learned that are important for further investigation.
Social bookmarking services became very popular recently. Easy of use, possibility to share and discover in addition to accessibility though the Internet, turns social bookmarking systems into powerful repository of shared knowledge. Obviously this attracts attention of educational institutions and recently such systems started to appear under their domains. However, usually these systems stay separate and limit their users by their bounds. It means that separate systems' students could reach each other and use knowledge base, aggregated in other systems. On the other side, institutions usually want to own this assembled data and do not give away collected knowledge base to third side. This issue does not allow building social bookmarking systems that can be used by multi-institutional users. An idea is to develop distributed system where every institution will have their own database, but, on the other hand, will allow exploring and using data from other network sources. This article overviews possible distributed system architecture models and suggests a solution that will eliminate such service issues. Moreover, two different approaches towards distributed services communication are evaluated in this article: SOAP vs. iCamp FeedBack. SOAP is a lightweight XML based protocol for exchanging structured information between distributed applications. FeedBack is another model that uses plain RSS feed to transmit data. Both models are tested and evaluated in this article.
Informatics is currently being taught in high schools all over the world. In the Dutch curriculum, computer literacy is taught in the lower grades as a compulsory subject, Informatics is taught as an elective in the higher grades of some schools. As a follow-up to the outline of Grgurina and Tolboom (2008), the discussion about the future of Informatics education in the Netherlands is investigated and elaborated in this paper. Our research brings forward four positions of the stakeholders in the field: the negative-critical view, the positive-realistic view, the no-nonsense view and the innovative view. Extreme positions are either `to terminate the school subject, because teachers are not qualified and there is little relation with Informatics as a scientific discipline', or `to strengthen the school subject because of its social relevance'. The latter position will be substantiated by a discussion of the novice-expert approach for teaching and the importance of enculturation and situated learning. As a way to strengthen secondary Informatics teaching, especially in the Netherlands, Schoenfeld's framework is advised (Schoenfeld, 2010).
The purpose and the main aim of the pedagogic experiment were to practically verify the success of Multimedia Teaching Aid (MTA) in conditions of primary schools. We assumed that the use of our multimedia teaching aid in teaching technical education on the 2nd level of primary schools would significantly affect the level of knowledge of pupils from the issue of Road Safety Education (RSE), particularly in terms of performing, remembering, understanding, specific transfer and active learning of pupils.
The Lithuanian Informatics Olympiad is a problem solving contest for high school students. The work of each contestant is evaluated in terms of several criteria, where each criterion is measured according to its own scale (but the same scale for each contestant). Several jury members are involved in the evaluation. This paper analyses the problem how to calculate the aggregated score for whole submission in the above mentioned situation. The chosen methodology for solving this problem is Multiple Criteria Decision Analysis (MCDA). The outcome of this paper is the score aggregation method proposed to be applied in LitIO developed using MCDA approaches.
The goal of this literature study is to give some preliminary answers to the questions that aim to uncover the Pedagogical Content Knowledge (PCK) of Informatics Education, with focus on Programming. PCK has been defined as the knowledge that allows teachers to transform their knowledge of the subject into something accessible for their students. The core questions to uncover this knowledge are: what are the reasons to teach programming; what are the concepts we need to teach programming; what are the most common difficulties/misconceptions students encounter while learning to program; and how to teach this topic. Some of the answers found are, respectively: enhancing students' problem solving skills; programming knowledge and programming strategies; general problems of orientation; and possible ideal chains for learning computer programming. Because answers to the four questions are in a way not connected with each other, PCK being an unexplored field in Informatics Education, we need research based efforts to study this field.
When first introduced to the analysis of algorithms, students are taught how to assess the best and worst cases, whereas the mean and amortized costs are considered advanced topics, usually saved for graduates. When presenting the latter, aggregate analysis is explained first because it is the most intuitive kind of amortized analysis, often involving enumerative combinatorics. We show how the aggregate analysis of functional queues can be carried out accurately and graphically, without combinatorics nor analytical tools like asymptotics, hence making it amenable to undergraduates. Our presentation is independent of any programming language.
Automated assessment technologies have been used in education for decades (e.g., computerised multiple choice tests). In contrast, Automated Essay Grading (AEG) technologies: have existed for decades; are `good in theory' (e.g., as accurate as humans, temporally and financially efficient, and can enhance formative feedback), and yet; are ostensibly used comparatively infrequently in Australian universities. To empirically examine these experiential observations we conducted a national survey to explore the use of automated assessment in Australian universities and examine why adoption of AEG is limited. Quantitative and qualitative data were collected in an online survey from a sample of 265 staff and students from 5 Australian universities. The type of assessment used by the greatest proportion of respondents was essays/reports (82.6%), however very few respondents had used AEG (3.8%). Recommendations are made regarding methods to promote technology utilisation, including the use of innovative dissemination channels such as 3D Virtual Worlds.
