Modern classroom learning models have delineated that student characteristics factors, the teaching context and the learning process all have important influence on learning outcomes. Biggs' 3P model of classroom learning has provided a comprehensive conception of the interrelationships of the various components involved. It has also provided a conceptual framework for many studies in student learning in recent years. Following Biggs' conceptual model, this study investigates students' personality characteristics, the learning context as perceived by learners, the way they go about studying and the influence they cast on achievement outcomes. Previous studies have shown that motivational orientations, self-esteem, and the way students approach their learning have effects on their academic achievement. Contextual factors such as course demand, workload pressure or method of assessment also contribute to the final learning outcomes. A number of studies have investigated the nature and the interrelationships of these variables following the quantitative paradigm. While the quantitative approach provides objective, scientific evidence, the opportunity for probing deeper into the phenomenological experiences of the learners is limited. It was believed that an investigation using a qualitative method would bring more light to the subject under study. This study adopts a qualitative approach making use of interview analysis to tap deeper into the causal attributions, self-concept, perceived environment and learning approaches of Hong Kong university students. The objective was to examine the complexities of these characteristics and their impact on academic achievement. The interview sample consisted of 36 students drawn from the construction and engineering discipline in one of the universities in Hong Kong. Of the 36 students, half were high achievers and half low achievers who represented the top 10% and the bottom 10% range of academic results respectively. The author carried
