This paper reports on a study of environments in emerging Internet classrooms. At issue for this study is to what extent these 'technological classrooms' are providing a positive learning environment for students. To investigate this issue, this study involved an evaluation of the physical and psychosocial environments in computerized school settings through a combination of questionnaires and ...

OBJECTIVES To investigate the sources of high concentrations of particles of < 10 microns diameter (PM10) in classrooms, observed in a previous study on childhood exposure to PM10, and to study the correlation between classroom and outdoor concentrations of mass and elements of PM10. METHODS Measurements of PM10 were conducted in two schools and outdoors in Amsterdam, the Netherlands. Averagi...

In this article we address a number of important issues that arise in the analysis of nonindependent data. Such data are common in studies in which predictors vary within "units" (e.g., within-subjects, within-classrooms). Most researchers analyze categorical within-unit predictors with repeated-measures ANOVAs, but continuous within-unit predictors with linear mixed-effects models (LMEMs). We ...

This study examined the effectiveness of a number sense program on kindergarten students' number proficiency and responsiveness to treatment as a function of students' risk for mathematics difficulties. The program targeted development of relationships among numbers (e.g., spatial, more and less). A total of 101 kindergarten students (not at risk: 22 control and 36 experimental; at risk: 18 and...

A S WALL STREET TRACKS THE HEALTH OF AMERICAN BUSIness by monitoring indicators of economic productivity, so must scientists, parents, and taxpayers heed leading indicators of scientific productivity. Since mathematics is the foundation discipline for science, the state of mathematics education is a crucial predictor of future national strength in science and technology. Evidence suggests that ...

This study details the initial development of the Responsive Environmental Assessment for Classroom Teachers (REACT). REACT was developed as a questionnaire to evaluate student perceptions of the classroom teaching environment. Researchers engaged in an iterative process to develop, field test, and analyze student responses on 100 rating-scale items. Participants included 1,465 middle school st...

Several approaches to teaching undergraduate physics and engineering students using both the Dunn and Dunn and the Kolb Learning Style Models are discussed. The Dunn and Dunn Learning Style Model is employed with non-majors enrolled in introductory physics at American University and the Kolb Learning Style Model is employed with freshman engineering students at Purdue University. The basic elem...

Multiple conceptualizations of the interrelation between assessment and learning yield three notions of assessment: assessment of learning, assessment for learning, and assessment as learning. This paper aims at uncovering roles and obstacles of assessment for learning and assessment as learning in English language classrooms in Hong Kong. Grounded upon the theory of constructivism and the noti...
