Evaluating students' learning experiences outcomes cannot be considered a simple task. This paper aims at investigating students' overall performance and the discriminating power of particular tests' items in the context of business courses. The purpose of this paper is to contribute with this issue while analyzing it, with scientific approach, from an accounting information systems standpoint: two experiments based on a database management system (DBMS) undergraduate course, involving 66 and 62 students (experiments E1 and E2, respectively). The discriminant analysis generated discriminant functions with high canonical correlations (E1= 0.898 and E2= 0.789). As a result, high percentages of original grouped cases were correctly classified (E1= 98.5% and E2= 95.2%) based on a relatively small number of items: 7 out of 22 items from E1 (multiple-choice), and 3 out of 6 from E2 (short-answer). So, with only a few items from the analyzed instruments it is possible to discriminate "good" or "bad" academic performance, and this is a measure of quality of the observed testing instruments. According to these findings, especially in business area, instructors and institutions, together, are able to analyze and act towards improving their assessment methods, to be of minimum influence while evaluating students' performance.

AbstractWider dissemination of medical digital video libraries is affected by two correlated factors, resource effective content compression that directly influences its diagnostic credibility. It has been proved that it is possible to meet these contradictory requirements halfway for long-lasting and low motion surgery recordings at compression ratios close to 100 (bronchoscopic procedures were a case study investigated). As the main supporting assumption, it has been accepted that the content can be compressed as far as clinicians are not able to sense a loss of video diagnostic fidelity (a visually lossless compression).Different market codecs were inspected by means of the combined subjective and objective tests toward their usability in medical video libraries. Subjective tests involved a panel of clinicians who had to classify compressed bronchoscopic video content according to its quality under the bubble sort algorithm. For objective tests, two metrics (hybrid vector measure and hosaka Plots) were calculated frame by frame and averaged over a whole sequence.

The case method can be classified as a type of experiential learning because students treat the problem in the case as if it were real and immediate. Until the Internet there was no practical way for cases to actually be real and immediate. The Internet makes possible instantaneous distribution of cases, and it makes possible their creation in real time. This article describes a recent attempt to use the Internet to bring business reality to business courses, and to facilitate communication among instructors, students, and the case company. It explores the challenges and difficulties involved in producing a new type of case study, and it assesses the feasibility of doing so on a regular basis. The goal of the author is to stimulate a dialog about how the Internet can be used to move forward all of our teaching methods, but especially the one that is prominent in schools of business: the case method.

Research demonstrates that the capacity to implement strategy and to execute plans drives business success (Hrebiniak, 2007) and that businesses’ inability to succeed by executing effectively arises from the ubiquitous incapacity of business professionals to overcome the gap between what they know and what they are actually able to do, whether personally or professionally (Pfeffer & Sutton, 2000). Research and experience also demonstrates that the capacity to execute is not primarily about operational or tactical skills.  Rather, it is more a “discipline to learn” (Bossidy, Charan & Burck, 2002; i.e., the capacity to execute is primarily a discipline of continuously learning to acquire, to interpret, and especially to apply information (Garvin, 2000) in a never-ending spiral of improvement. Business professionals must possess this capacity in order to succeed over the long-term. The purpose of business education is to prepare professionals for successful performance in businesses.  However, unlike the preparation of medical doctors and many other professionals, the education in most business schools remains more theoretical than experiential in the andragogy employed. Even the typical case study, like many instructional techniques used in business schools, is still relatively “theoretical” in that it is not a business experience in which the student is personally involved. This paper introduces an instructional method, the journal entry assignment, to help address the challenge of creating a more experiential education and preparation for business. This assignment enables students to “learn by doing” and, in effect, it creates a “living case study” experience for students.

E-business courses were introduced in many universities around the world about ten years ago. Sometimes they were introduced at the undergraduate level, sometimes at postgraduate level and sometimes at both. This paper will present a case study examining the postgraduate e-business courses in two Australian universities and how they have changed over the last few years. The paper describes factors that influence the development of e-business courses and outlines a theory of subject development, originally intended to explain the development of new school subjects in 19fe century England. We make use of this theory to explain what has happened, and is still happening, in the case of e-business curriculum in Australia.

Living Case Studies (LCSs) in the discipline of business provide a bridge from knowledge acquisition to knowledge practice in a real world context. They offer the facilitator a knowledge to application methodology and the student a learning by doing experience, which are oftentimes lacking in business courses. The Eynesbury Institute of Business and Technology (EIBT) offers a Diploma of Business leading to either the University of Adelaide or University of South Australia's degree programs in business-related fields. From 2010-2013, EIBT introduced a simulated LCS in its Diploma of Business program to extend collaborative methods and understanding of how different business courses can work together to achieve heightened student engagement. This chapter provides an overview of the journey from planning to implementation, approaches adapted in different courses, reflections on what was learned, and future recommendations if the LCS were to be re-implemented at EIBT.
