This paper proposes and validates a short and simple Expectancy-Value-Cost scale, called EVC Light. The scale measures the motivation of students in computing courses, allowing the easy and weekly application across a course. One of the factors related directly to the high rate of failure and dropout in computing courses is student motivation. However, measuring motivation is complex, there are several scales already carried out to do that job, but only a few of them consider the longitudinal follow-up of motivation throughout the courses. The EVC Light was applied to 245 undergraduate students from four universities. The Omega coefficient, scale items intercorrelation, item-total correlation, and factor analysis are used to validate and measure the reliability of the instrument. Confirmatory and exploratory factor analyses supported the structure, consistency, and validity of the EVC Light scale. Moreover, a significant relationship between motivation and student results was identified, based mainly on the Expectancy and Cost factors.

Weblogs are a popular form of easy-to-use personal publishing that has attracted millions of bloggers to share their personal thoughts, opinions, and knowledge on the web. The versatility of weblogs as a communication medium has attracted interests from educators. Educational applications of weblogs have so far included journals, e-portfolio, learning diaries, and logbooks. As in the case of other educational technologies, the perception of students is a determinant factor of whether weblogs are used in a way that elicits educational values. This paper investigates student perception towards the purposes of blogging. It reports an experience of introducing blogging tasks to third year computing students, and compares their perception with students not participating in the blogging tasks. A student perception model is proposed to explain the difference in the perception due to the experience in blogging. The paper concludes that mandatory use of weblogs in a course can gradually cultivate educationally sound perceptions in students despite of the observed misuse.
