Study Design: This is to widen the dissemination of results to the community which information technology practices and theory can address. Place and Duration of Study: This project tries to investigate the possible outcomes by developing an online repository for research and capstone project in Southern Philippines Agri-Business and Marine and Aquatic School of Technology that can deposit students output, register various accounts, log transactions and an interactive website. Methodology: Innovative research approach is being manifested in the development that uses modified waterfall, white-box testing and survey-type methodologies are being highlighted. Results: The website is successfully developed with specific functionality on referencing, data storage, data security, data extraction and some special functionalities. The fifty evaluators gave

Structured approaches provide a prescription and guidelines for how to go about the process of developing an information system, are relatively easy to learn and provide tools which are well suited to their task. However, the products of structured approaches are sometimes seen to be vague and imprecise since requirements are written using natural language or represented in the form of models which do not have a formal foundation. This vagueness or ambiguity can be the source of problems later in development of the information system. A possible solution to this is to represent requirements using formal methods since these are seen as precise and unambiguous. However, formal methods are typically only a mathematical language for representing requirements. They are often regarded as difficult to learn and use. Even though formal methods of one sort or another have been in existe...

The DWBA program DWUCK has been used to fit the differential cross sections with no free parameters. The optical model parameters for the proton-residual nucleus channel were taken from the literature, and the 3He-target nucleus channel parameters were obtained by fitting the 3He elastic scattering differential cross sections.

From the perspective of both the student and the academic, fair, just and accountable assessment is the ideal, however often difficult to achieve. Previous research by the authors presented a paper based toolkit to assist supervisors in both formative and summative assessment of capstone projects that does not focus entirely on the final product. Trials of the toolkit demonstrated that although it provided an excellent measure of individual student contribution and achievement, it required an inordinate amount of work by both parties to be efficient and effective. To alleviate the workload and provide individual and comparative instant feedback, an online version of the TCS System, has been developed and tested by studen...

The aim of the capstone unit is to develop students' expertise in information systems analysis by exposing students to projects set in realistic environments, working with supervisors experienced in systems analysis. Students are formed into teams and work in the role of information systems analysts with industry clients on real world organizational problems typically related to process improvement in information technology. The research for this paper is performed through the use of structured reflective journals where the students are required to answer a wide ranging set of questions. These questions are designed to encourage students to reflect on their understanding of both the project and the process of systems analysis. This paper reports on t...

Students are formed into teams and work in the role of information systems analysts with industry clients on real world organizational problems. The research for this paper is performed through the use of reflective journals in which students are required to answer a wide ranging set of questions related to tasks involved in the ISA process. These questions are designed to encourage students to reflect on their understanding of both the project and the process of systems analysis. This paper reports on students’ reflections on their interviews with their clients from industry in which they describe their interactions and perceptions of their clients and their understanding of the client’s problem. Teams are allocated a supervisor with substantial industry experi...

From the perspective of both the student and the academic, fair, just and accountable assessment is the ideal, however often difficult to achieve. Previous research by the authors presented a paper based toolkit to assist supervisors in both formative and summative assessment of capstone projects that does not focus entirely on the final product. Trials of the toolkit demonstrated that although it provided an excellent measure of individual student contribution and achievement, it required an inordinate amount of work by both parties to be efficient and effective. To alleviate the workload and provide individual and comparative instant feedback, an online version of the TCS System, has been developed and tested by students and staff. This paper reviews and discusses the structure and benefits of the online system and the results of the software testing in relation to educational values.

Current research is limited and requires solutions that are not subjective, enable formative and summative assessment with student input and are not onerous on supervisors and/or students. This paper draws on input from highly experienced academics supervising capstone projects in ICT, critically reviews recent publications pertaining to capstone project assessment and current capstone students opinions. The outcome of this input led to the development, trial and evaluation of a toolkit to assist supervisors in both formative and summative assessment of capstone projects.
