Six preschool classrooms, containing children between the ages of 4.0 and 40.0 months, were seeded with miniature items to examine how easily scale errors could be elicited. Observations occurred over a period of 3 months, with a total of 280 min of observations per classroom. A concealed observer documented all interactions with the miniature items. A total of 93 scale errors occurred, with a ...

A Framework for K–12 Science Education identifies eight science and engineering practices for K–12 classrooms. These practices, along with core ideas and crosscutting concepts, define our nation’s learning goals for science. An important advance from earlier standards (AAAS 1993, NRC 1996), these practices are clearly identified not as separate learning goals that define what students should kn...

BACKGROUND Relationships between indoor air quality (IAQ) found in schools and the allergic and respiratory health of schoolchildren have been insufficiently explored. A survey was conducted in a large sample of classrooms of primary schools in France to provide objective assessments of IAQ to which young schoolchildren are exposed in classrooms, and to relate exposure to major air pollutants f...

BACKGROUND Visual demands of school children tend to vary with diverse classroom environments. The study aimed to evaluate the distance and near Visual Acuity (VA) demand in Indian school classrooms and their comparison with the recommended vision standards. MATERIALS AND METHODS The distance and near VA demands were assessed in 33 classrooms (grades 4 to 12) of eight schools. The VA threshol...

This paper presents a classroom observation protocol and analysis method that efficiently capture key student and teacher discursive moves. We developed this protocol for use in a study comparing classrooms using Eduinnova, handheld computer-supported collaborative learning software, with classrooms using a popular, non-collaborative software application aimed at the same topic. Analysis of dat...
