The Revised Two-Factor Study Process Questionnaire (R-SPQ-2F): Exploratory and confirmatory factor analyses at item level

Abstract: The underlying structure of the Revised Two Factor version of the Study Process Questionnaire (R-SPQ-2F), a 20-item instrument for the evaluation of students' approaches to learning (SAL), was examined at item level using two independent groups of undergraduate students enrolled in the first (n=314) and last (n=522) years of their studies. The methods used were (a) Exploratory factor analysis (EFA) assisted by rigorous procedures such as Velicer's MAP test, parallel analysis and the Schmid Leiman solution with the first sample; and (b) confirmatory factor analysis (CFA) with the second sample. The results of EFA indicated that the latent structure of the R-SPQ-2F is best described by two factors and the results of CFA suggested that out of four a priori structural models, the best fit was achieved by a simple first-order two-factor model. Taken together, these results seemed to converge, suggesting (a) that SAL might be defined as a co-variation between a motive and its intended strategy, these not necessarily being divided into separate first-order factors (subscales), and (b) that the underlying structure of the R-SPQ-2F is apparently non-hierarchical, being best described by a parsimonious first-order two-factor model in which Deep and Surface learning approaches are each measured by their ten corresponding items.

Digestive enzyme activity during larval development of the Senegal sole (Solea senegalensis)

Abstract: The activities of the main digestive enzymes (proteases, amylase, lipase) as well as those of acid and alkaline phosphatases were assessed during the larval development of the Senegal sole, Solea senegalensis. Important variations in specific activities of all the enzymes were observed during the period of study and were mostly related to the beginning or the end of metamorphosis. Both acid and alkaline protease activities were identified at early stages of development. Acid proteases accounted for only 10% of total protease activity in a 9 days-old larva, but exceeded 75% in a 33 days-old individual. Maximum lipase activity was related to the development of exocrine pancreas (days 6 to 10) and to metamorphosis. It is suggested this can be related to the metabolism of lipid reserves taking place during this morphological change. Activity of alkaline phosphatase decreased from day 5 to day 20 but therafter revealed a sharp increase, possibly linked to the development of enterocytes. The pattern of development of the main digestive enzymes found in S. senegalensis is similar to that described in other flatfish species.

The 'Ideal Teacher'. Implications for student evaluation of teacher effectiveness

Abstract: Assessment of teachers through student opinions has been the most used method to define the characteristics of teaching quality. There is no previous literature applying the Semantic Differential (SD) with this objective. SD can detect the attributes of the 'ideal teacher', and find the evaluative, emotional or affective components linked to this concept. In this work, we analyse the factorial structure of a SD scale, to test the hypothesis of the existence of EPA factors, usually found in research directed to different objects of attitude. The most relevant dimensions of the 'ideal teacher' show similar profiles to those dimensions obtained with other assessment procedures. This result confirms the adequacy of SD as an instrument to assess of quality teaching.
