The role of adolescents' disclosure to their parents in their academic adjustment was examined in a study of 825 American and Chinese adolescents (mean age = 12.73 years). Four times over the seventh and eighth grades, adolescents reported on their spontaneous disclosure of everyday activities to their parents, the quality of their relationships…

Building on longitudinal findings of linkages between aspects of teachers' language during instruction and children's use of mnemonic strategies, this investigation was designed to examine experimentally the impact of instruction on memory development. First and second graders ("N" = 54, "M"[subscript age] = 7 years)…

This research examined how motivation (perceived control, intrinsic motivation, and extrinsic motivation), cognitive learning strategies (deep and surface strategies), and intelligence jointly predict long-term growth in students' mathematics achievement over 5 years. Using longitudinal data from six annual waves (Grades 5 through 10;…

This research examined motivational trajectories during early adolescence in the United States and China. Upon their entry into middle school at 7th grade and every 6 months thereafter until the end of 8th grade, 825 American and Chinese children (mean age = 12.73 years) reported on their motivational beliefs (e.g., mastery orientation) and…

Explaining new ideas to oneself can promote transfer, but how and when such self-explanation is effective is unclear. This study evaluated whether self-explanation leads to lasting improvements in transfer success and whether it is more effective in combination with direct instruction or invention. Third- through fifth-grade children (ages 8-11;…

Employed a trial-by-trial analysis of spelling-strategy use to examine whether the overlapping-waves model could account for strategy choices in spelling for children tested in first and second grade. Found that the model was useful for understanding the development of spelling, despite the fact that explicit use of backup strategies had a minimal…

This study explored 5- to 17-year-olds' use, self report, and awareness of verbal problem-solving strategies and strategy effectiveness. Findings indicated that children's verbal strategies moved from overt, to partially covert, to fully covert forms with age. Self-reports of strategy use were accurate yet incomplete. Strategy awareness was low…

Proposes that conceptual change is constrained by the child's conceptual structures and the structures inherent in problem-solving tasks. Uses a microgenetic case study and group data to examine how interaction between strategies children bring to a task and the detailed task structure redirect children's attention and create the possibility of…

Assessed the arithmetical competencies of 105 American and 104 Chinese elementary school students at the beginning and end of the U.S. school year. Results suggest the Chinese advantage in early mathematical development is related to a combination of language- and school-related factors. (MDM)
