Research paper thumbnail of ASSESSMENT OF STUDENTS' COGNITIVE-AFFECTIVE STATES IN LEARNING WITHIN A COMPUTER-BASED ENVIRONMENT: EFFECTS ON PERFORMANCE

This paper presents an investigation of students' cognitive-affective states (i.e., engaged concentration, anxiety, and boredom) when they learn a particular course within CBL systems. The results of past studies by other researchers suggested that certain cognitive-affective states; particularly boredom and anxiety could negatively infl uence learning in a computer-based environment. This paper investigates the types of cognitive-affective state that students experience when they learn through a specifi c instance of CBL (i.e., a content sequencing system). Further, research was carried to understand whether the cognitive-affective states would infl uence students' performance within the environment. A one-way between-subject-design experiment was conducted utilizing four instruments (i) CBL systems known as IT-Tutor for learning computer network, (ii) a pre-test, (iii) a post-test, and (iv) self-report inventory to capture the students' cognitive-affective states. A cluster analysis and discriminant function analysis were employed to identify and classify the students' cognitive-affective states. Students were classifi ed according to their prior knowledge to element the effects of it on performance. Then, non-parametric statistical tests were conducted on different pairs of cluster of the cognitive-affective states and prior knowledge to determine differences on students' performance. The results of this study suggested that all the three cognitive-affective states were experienced by the students. The cognitive-affective states were found to have positive effects on the students' performance.

However there has previously been little published empirical evidence to either prove or disprove this assertion. A survey carried out in March 2006 gathered responses from a large number of software development professionals who were using many different methods, both traditional and agile. A statistical analysis of this data reveals that agile methods do indeed improve outcomes from software development projects in terms of quality, satisfaction, and productivity, without a significant increase in cost. However, adoption of methods appears to involve a high degree of adaptivity, with many methods being used in combination and sets of techniques being adopted on an ad hoc basis. In this context, our analysis suggests that choosing specific combinations of methods can be particularly beneficial. However, we also find that successful adoption of an agile method is to some extent dependent on rigorous integration of certain core techniques.

Most work on student models describes the student's understanding of any domain. A few works were done on studying student's individual features; however, little has been investigated on personality features due to the difficulty of encompassing all the different personality features. In this context, this paper aims to answer what personal characteristics of Arab students might contribute to this problem. A study using MBTI questionnaire model was conducted in at Dhofar University in Oman to understand Arab student's personality features.

Traditionally, face-to-face classroom environments have been considered as a most effective way to deliver information or knowledge from the educator to the learner, which all of us have bred in this type of learning setting. ...

This paper describes four generic software architectures that can be applied to M-learning systems and provides an overview of their comparative strengths and weaknesses in meeting the various requirements of the mobile learner.

As agile methods have become increasingly popular, they have begun to replace structured approaches to software engineering. Usability engineering has historically tended to follow a development approach that is similar to traditional software engineering, rendering it apparently incompatible with agile methods. The focus of this paper is an analysis of the relationship between agile practices, on the one hand, and current practices of usability engineering on the other. We provide an experience report from an organisation where usability engineering has been integrated into an agile software development method. From this context we identify areas of compatibility and also areas of conflict, and suggest some strategies for agile development teams to incorporate key practices from usability engineering, while at the same time suggesting that usability engineers should embrace relevant agile techniques.
