Nineteen teachers also participated in order to validate the…

We conducted a pretest-posttest study using measures of higher order thinking skills (HOTS), and lower order thinking skills (LOTS) in six 12th-grade American Government classrooms taught by three experienced teachers over one semester. One of the three teachers implemented a curriculum in two classes based on experiential education (EE)…

This study examined the effectiveness of a Question Exploration Routine and associated graphic organizer for enhancing the performance of students of diverse abilities when assessed on knowledge and comprehension of content and quality of written responses. Participants were 36 students with and without learning disabilities (LD) in Grades 9…

It has been almost 30 years since the last systematic look at writing instruction in middle schools and high schools in the United States (Applebee, Writing). Since that report, there have been a number of significant changes in the contexts in which teachers teach and in which their students learn to write. Stretching back to the 1969-70 school…

To many, it seems obvious which schools are failing--schools whose students perform poorly on achievement tests. But since evaluating schools on achievement mixes the effects of school and nonschool influences, achievement-based evaluation likely underestimates the effectiveness of schools that serve disadvantaged populations.

The purpose of this study was to investigate the meanings that a teacher associated with calculators as reflected in the teacher's use of calculators in two 12th-grade mathematics courses, and to link those meanings to the institutions and individuals that supported the development of those meanings. By describing the teacher's conceptions of his…

Since 1995, astronomers have discovered over 100 known exoplanets--planets outside of the solar system--and determined their properties such as mass, orbital distance, size, and density. By using simple algebraic equations of physics, students can determine these properties as well. In this article, the author discusses an activity titled…

This article explores the conceptual change of students in Grades 10 and 12 in three Australian senior high schools when the teachers included computer multimedia to a greater or lesser extent in their teaching of a genetics course. The study, underpinned by a multidimensional conceptual-change framework, used an interpretive approach and a…
