Lists 30 reminders for successfully communicating with students and nurturing their interest in science. Each reminder is accompanied by specific strategies for working with middle school students. (DDR)

Explores the influences of text structure on students' conceptual change. Case studies were conducted and results showed that individuals used refutational text to change their alternative conceptions and acquire new concepts. Findings indicate that refutational text does cause cognitive conflict. While refutational text is effective for groups,…

Explores a set of pedagogic practices in a 'progressivist' classroom as practices of covert institutional regulation. The article attempts to show how the instructional potential of the pedagogic act is subordinated to the regulative rules of the institutional context of the classroom, so that following classroom rules becomes the main focus of…

Discusses an experiment in testing college students in France on their recall of newly learned English words in order to compare the advantages and disadvantages of context and translation learning as a function of learner proficiency. Results reveal a superiority of translation learning in terms of quantity, but an inability of weaker learners to…

Examines the differences between language teaching in private and public institutions in the same country. The study uses learners' reports on how they are taught and how they learn new English vocabulary as a guide to examine the differences between the two prevailing pedagogical environments in Greece--private institutes of foreign languages and…
