Abstract
This article focuses on comparing two e-learning strategies (cooperative versus collaborative) in terms of developing preservice teachers' skills in designing one of the modern Web 2.0 assessment tools (i.e., e-portfolio) and their effects on product quality and achievement motivation towards designing e-portfolio. After the experiment involving 80 students from the third level at the faculty of education, King Faisal University in Saudi Arabia, during the first semester of the school year 2017/2018, a questionnaire on achievement motivation and a product quality assessment card were used. The results show no significant difference between the two e-learning strategies regarding students' achievement motivation. On the other hand, there is a significant difference in product quality in favor of cooperative e-learning. The study highlights social-network based e-learning strategies of developing preservice teachers' teaching and evaluating skills that they need to apply in the new digital era.
