The ability to recognize equivalent algebraic expressions quickly and confidently is important for doing mathematics in an intelligent partnership with computer algebra. It is also a key aspect of algebraic expectation, the algebraic skill that parallels numeric estimation. The progress in this ability of 50 students learning mathematics with CAS…

This article describes a chemical-processing program at Saginaw Career Complex in Saginaw, Michigan. The program is preparing 42 11th- and 12th-graders to work as chemical-processing operators or technicians by the time they graduate from high school. It was developed in partnership with the Saginaw Career Complex--one of 51 centers in the state…

Introduction: This research sought to investigate how school students build on their existing knowledge of a curriculum topic and transform found information into personal knowledge, and how their knowledge of this topic changes. Method: The qualitative study involved 574 students from Grades 6 to 12 in ten New Jersey schools. The context for data…

Genetic engineering is now an integral part of many high school textbooks but little work has been done to assess whether it is being properly addressed. A checklist with 19 items was used to analyze how genetic engineering is presented in biology textbooks commonly used in Spanish high schools, including the content, its relationship with…

The present study uses item response theory (IRT) to establish comparability between the English and Portuguese versions of the Goal Instability Scale (GIS), a measure of generalized motivation. A total of 2,848 American and 679 Portuguese high school students were administered their respective language versions of the GIS. Results showed only…

To find out whether high school grade inflation exists, data drawn from students who took the ACT in the eleventh or twelfth grades and graduated from public high schools were examined. Because grade inflation is by definition a factor that develops over time, data from a relatively long period, 1991 to 2003, or 13 years were used. The number of…

The contribution of nonfamily adults to young people's well-being was explored using both a cross-sectional national sample of 614 12- to 17-year-olds and a longitudinal sample of 370 students followed from 6th-8th grades through 10th-12th grades. Both variable- and person-centered analyses were employed. Young people's involvement in…

Our main goal in this study was to explore whether the use of models in molecular genetics instruction in high school can contribute to students' understanding of concepts and processes in genetics. Three comparable groups of 11th and 12th graders participated: The control group (116 students) was taught in the traditional lecture format, while…

This study, using a non-experimental, exploratory and descriptive method, established learners' and educators' views about factors that contribute to poor performance in mathematics and physical science. Participants were purposefully selected from seven schools with poor pass rates in District 3 of Tshwane North. Focused group interviews with ten…

This study uses an existing astronomy software program to encourage inquiry-based learning and argumentation while also ensuring gains on conventional classroom assessments and high-stakes achievement tests. To supplement the software program, a curriculum and three levels of assessment--quizzes, exam, and test--were designed and administered to…
