That is, instead of creating an extra assessment outside the normal activities of the course, this paper examines an assessment that is part of the course. Additionally, not only is the course embedded assessment part of the course, it measures 100% of assessments employed in the course, instead of only a sample of the assessments. This paper presents background information regarding the utilization of a course embedded assessment, including The Association to Advance Collegiate Schools of Business International [AACSB] requirements for fulfilling assessment of learning outcomes. Discussion of course embedded assessments takes place. The dialogue then illustrates an approach that can be used for the data organization and analysis stages of assessment. It is hoped that the use of such an approach may save instructors time and effort in their assessment endeavors, while providing a superior quality assessment encompassing the entire course instead of merely a sample. This occurs by transferring the objective nature of the assessments into a computerized format.展开更多

Concern was raised that Islamic Studies faced the risk of being misunderstood if the lessons were taught through self-accessing method with minimal intervention from teachers. Using the Dick and Carey instructional model as a framework, an e-learning version was devised for the national Form 4 Islamic Studies syllabus, "The steps and procedures of Hajj and Umrah". The Islamic Studies textbook for national secondary schools in Malaysia was reviewed using a systematic approach, from identifying the instructional goal through to formative and summative evaluation processes. Interview sessions with students were conducted to assess the developed e-learning Islamic Studies content. A subsequent survey with students was conducted. Results from the study indicated the e-learning Islamic Studies content had the potential to help students, being easy to use, and attracting and retaining students' attention.展开更多
