O ensino da biologia numa perspectiva por pesquisa : contributos de uma investigação preliminar no ensino secundário

De entre as várias perspectivas para o Ensino das Ciências, o "ensino por pesquisa" (EPP) tem sido aquela que, nos últimos tempos, reúne consenso alargado em relação às suas potencialidades na construção de conhecimentos, contribuindo positivamente para a formação pessoal e social dos alunos. Neste estudo, de carácter preliminar, pretende-se fazer uma análise ao desenvolvimento, por parte de alunos do ensino secundário, de conhecimentos conceptuais, processuais e atitudinais, em todos os momentos do EPP. Uma primeira análise aos dados recolhidos faz emergir alguns indicadores que apontam para a eficácia de uma estratégia de ensino e de aprendizagem baseada na perspectiva de EPP

Two of the six simultaneous paths are statistically significant in the direction from 3 and 6 months' gQOL towards the corresponding scores on the SF-36 General health subscale. As with the cross-lagged paths, this model includes strong serial associations over time within each variable except between 6 and 12 months' general health perceptions. Straight and curved single arrows indicate the causal paths modeled. The corresponding decimals are standardized regression coefficients. Bold face coefficients indicate p < 0.05 while broken lines are used for paths with a corresponding p ≥ 0.05. The curved line between baseline variables represents a correlation; the number is the corresponding correlation coefficient. Model fit indices are summarized in Table 3. For correct model specification of simultaneous effects, the present baseline assessment provides exogenous and correlated variables, without simultaneous effects at this time-point
