A sociocultural perspective on mediated activity in third grade science

This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment. The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science. The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed.

英语分层次教学的探索与实践

诸如翻译法、直接法之类的传统英语教学法,在某个历史时期或某种程度上促进了英语教学,但它们未必具有恒久的生命力。因为它们在寻找教学突破口的时候,把注意力只放在英语自身环节上,而忽视了教学对象——学生个体。在教学中学生是主体、内因;而教学方法只是途径、外因。内因决定外因,外因要通过内因起作用。要有效地促进英语教学,就必须“治标先治本,”因为学生个体始终是教学过程中最为关键性和决定性的一环。
