Watson, Jane M.; Kelly, Ben A. – School Science and Mathematics, 2005
This study uses the context of the weather to explore the development of students' intuitive ideas of variation from pre-Grade 1 to Grade 9. Three aspects of understanding these intuitions associated with variation are explored in individual videotaped interviews with 73 students: explanations, suggestions of data, and graphing. The development of…

Gardner, Catherine M.; And Others – School Science and Mathematics, 1992
Reports a study that compared the effects of three methods of instruction, use of hands-on activities, hands-on activities in combination with computer-assisted instruction (CAI), or text-based activities, on student achievement and attitude. Results indicated students receiving a combination of hands-on activities with CAI scored significantly…

Sunal, Dennis W., Ed.; Tracy, Dyanne M., Ed. – School Science and Mathematics, 1993
Describes an activity in which the students utilize the mathematics concepts of ratio, proportion, and data tabulation to examine the relationship between air pressure, temperature, and humidity. Students learn to approximate partial pressure by using humidity and temperature readings and by interpolating from the vapor pressure-temperature table.…
