This study examines the development of technology, pedagogy, and content knowledge (TPACK) in four in-service secondary science teachers as they participated in a professional development program focusing on technology integration into K-12 classrooms to support science as inquiry teaching. In the program, probeware, mind-mapping tools (CMaps),…

The present article presents a didactic proposal oriented to teaching notions of semiconductor physics in secondary education. The methods and the results of a pilot study designed to analyse the effectiveness of a teaching sequence on the topic are also described. The subjects were 60 students, aged 14-15 years, of a secondary school in Seville,…

Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students' interests in participating in opportunities to do real science? What are the discursive "resources" they draw on to introduce authentic science to students? The purpose of…

The teaching of science, especially at pre-college and teacher education levels has undergone tremendous transformation over the years: from teacher-centred transmission to student-centred approaches rooted in constructivism. Whereas constructivism has been charged with all manner of shortfalls, it still can be of benefit to the way physics…

"Situational interest" is a short-term form of motivation which occurs when a specific situation stimulates the focused attention of students (e.g., a spectacular science demonstration could arouse transient interest amongst nearly all the students in a class, even those who are not normally interested in science). However, there have…

Described is the use of filmed sequences in conjunction with multiple choice tests to extend the range of behaviors that can be assessed. The research was completed with students aged 13-14 who had studied Nuffield 0-Level chemistry. (RH)

The distinctive character of this work consists in the treatment of the whole Animal Kingdom as a unit; in the comparative study of the development and variations of organs and their functions, from the simplest to the most complex state; in withholding Systematic Zoology until the student has mastered those structural affinities upon which true…

Determined were (1) the effectiveness of a series of Biological Science Curriculum Study (BSCS) Single Topic Film Loops to improve, in five periods of instruction, the ability of high school biology students to construct hypotheses relevant to selected questions on the investigator's test, and (2) whether a relationship existed between students'…
