The purpose of this study is to compare the efficacy of three different approaches to professional development in Earth science education: preparing teachers to "adopt" expert-"design" curricula; preparing teachers to use a principled approach to design curricula; and preparing teachers to use a principled approach to "adapt" curricula. The claims…

Numerous investigations show that most school science teaching, in Spain and elsewhere, implicitly transmits an inductivist and very stereotyped view of science and conveys an unrealistic image of scientific work. We present some results of an investigation with fourth-level Spanish secondary education students (15 year olds) who were taught…

This study investigated the effects of using the cooperative concept mapping (CCM) teaching approach on secondary school students' motivation in biology. A non equivalent control group design under the quasi-experimental research was used in which a random sample of four co-educational secondary schools was used. The four schools were randomly…

This paper focuses on blended learning in mathematics I module in elementary calculus, at a University of Technology. A computer laboratory was used to create a learning environment that promoted interactive learning together with traditional teaching. The interactive learning was performed using projects to optimize the discovery and error…

This paper explores "meaningful learning" as influenced by "constructivism." The study focused on assessing and comparing the quality of essays written by students who learnt a given topic in a classroom setting ("control") to those who learnt the same topic in the field ("experimental").

We report the results of a controlled evaluation of an interactive on-line tutoring system for high school math achievement test problem solving. High school students (N = 202) completed a math pre-test and were then assigned by teachers to receive interactive on-line multimedia tutoring or their regular classroom instruction. The on-line tutored…

An approach to the analysis of an aptitude-treatment-interaction (ATI) design in which the treatment groups are based on an underlying factorial structure is described and illustrated. The approach emphasizes description with point and interval estimation. The example design considered consisted of two nominal treatment variables and one interval…

Research was conducted on pilot stress during simulated emergency flight conditions. Catecholamine (adrenaline and non-adrenaline) secretion for twenty United States Air Force student pilots and thirteen instructor pilots was determined during daily activities, during simulated flights performed in high realism simulators, and during actual…

The experiment studied the "relative effectiveness of tangible and social rewards upon the performance of a simple discrimination learning task by culturally disadvantaged children." Also assessed were the effects of the sex of the subjects (Ss) and the examiner. Ss were 144 five- and six-year old youngsters in a Georgia Head Start…

The purpose of this study was to determine the efficacy of induced affect as a pregroup training experience for coping with stress related to participation in an encounter group. Twenty-six subjects who volunteered to participate in an encounter group randomly were assigned to three treatment groups: Induced Affect Training plus the Encounter…
