This study extends previous research on the long-term connections between motivation constructs in expectancy-value theory and achievement outcomes. Using growth mixture modelling, we examined trajectories of change for 421 students from 4th grade through college in their self-concept of ability (SCA) in math, interest in math, and perceived…

A developmental writing scale for timed essay-writing performance was created on the basis of automatically computed indicators of writing fluency, word choice, and conventions of standard written English. In a large-scale data collection effort that involved a national sample of more than 12,000 students from 4th, 6th, 8th, 10th, and 12th grade,…

This report describes the development of grade norms for timed-writing performance in two modes of writing: persuasive and descriptive.

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…

Longitudinal study of mathematics achievement and gender of (n=60) students progressing from 6th to 12th grade found consistent gender differences in stereotyping mathematics as a male domain; identified no difference in spatial, verbal, or mathematics skills; and found positive correlation between achievement and confidence. (17 references)…

The long-term effectiveness of Drug Abuse Resistance Education (D.A.R.E.) was assessed by contrasting drug use and other D.A.R.E.-related attitudinal latent variables among 356 12th graders who received the program in 6th grade with 264 students who did not receive the program. Results suggest a possible sleeper effect for the program. (SLD)

Over 6,000 sixth- and twelfth-grade students from 33 school districts in Kansas were tested in 13 areas of academic and non-academic skills: arts and humanities; communication; mathematics; career preparation; consumer preparation; environmental education; health; nutrition; preparation for a changing society; safety; self concept; science; and…

The goals of this study were to trace the development of students' desire to participate in mathematics or to avoid it whenever possible, and to examine closely differences between boys and girls in reasons for enrollment or avoidance. To trace this decision-making process, information was collected from nearly 2,000 students. In the 1976-77…
