Abstract
The evaluation or assessment of student performance and knowledge is a central element of most instructional design models, as it provides the information required to take remediation actions and improve the learning process. However, the assessment contexts present such a diverse range of cases due to course, teacher and student idiosyncrasies that it is difficult to support all the possibilities via software. To deal with this problem, this paper presents an architecture that satisfies the requirements to support complex assessment scenarios, those that potentially involve different evaluators using diverse assessment methods, tools and techniques at the same time. An analysis of the literature and the assessment scenarios of courses from Computer Engineering grades was carried out to identify the requirements for systems that support such complex assessment scenarios and to infer the information needed to support them. This information was modeled and formalized in the Complex Assessment Scenarios Architecture (CASA) that comprises functional modules, knowledge bases and the relationships among them. Following this architecture, an assessment system (AdESMuS) was developed using agile methodologies. AdESMuS has been satisfactorily tested under different complex assessment scenarios proving to be able to support those scenarios' requirements. This paper presents CASA, the architecture for developing a system to support complex assessment scenarios along with the satisfactory case study of AdESMuS.
Highlights
Instructional design refers to the practice of creating ‘‘instructional experiences which make the acquisition of knowledge and skills more efficient, effective and appealing’’ [1]
All these aspects are even more important in complex assessment scenarios, i.e. those that involve several evaluators potentially using a combination of assessment methods, tools and techniques
With these concerns in mind, this paper presents CASA (Complex Assessment Scenarios Architecture), a flexible software architecture that supports complex continuous assessment processes and can compile information from different sources using different assessment tools
Summary
Instructional design refers to the practice of creating ‘‘instructional experiences which make the acquisition of knowledge and skills more efficient, effective and appealing’’ [1]. Rubrics are helpful tools for feedback processes because students receive all the necessary details about the goals not achieved in the assignment, and they are even given suggestions for attaining better performance (in the form of descriptions of the higher performance levels) [8] All these aspects are even more important in complex assessment scenarios, i.e. those that involve several evaluators potentially using a combination of assessment methods, tools and techniques. With these concerns in mind, this paper presents CASA (Complex Assessment Scenarios Architecture), a flexible software architecture that supports complex continuous assessment processes and can compile information from different sources using different assessment tools This architecture has been defined taking into account the needs of blended learning environments which are one of the main current trends in higher education [9].
