Abstract Labeling promotes infants' object categorization even when labels are rare. By 2 years, infants engage in "semi-supervised learning" (SSL), integrating labeled and unlabeled exemplars to learn categories. However, everyday learning contexts pose substantial challenges for infants' SSL. Here, two studies (n = 74, 51% female, 62%…

Ninety-seven children aged 4-11 (49 males, 48 females, mostly White) were given the opportunity to improve their problem-solving performance by devising and implementing a novel cognitive offloading strategy. Across two phases, they searched for hidden rewards using maps that were either aligned or misaligned with the search space. In the second…

This study examined age-related differences in the effectiveness of two generative learning strategies (GLSs). Twenty-five children aged 9-11 and 25 university students aged 17-29 performed a facts learning task in which they had to generate either a prediction or an example before seeing the correct result. We found a significant Age × Learning…

This study examined the direct and indirect associations of teachers' depressive symptoms with children's math achievement through teachers' reports of family-teacher relationships and children's approaches to learning (ATL) in Head Start. This study included 3- and 4-year-old 1,547 children (49% female; 27% White, 24% Black, 41% Hispanic/Latino,…

Researchers examined whether contingent experience using a touch screen increased toddlers' ability to learn a word from video. One hundred and sixteen children (24-36 months) watched an on-screen actress label an object: (a) without interacting, (b) with instructions to touch "anywhere" on the screen, or (c) with instructions to touch a…

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)…

Identity is often studied as a motivational construct within research on adolescent development and education. However, differential dimensions of identity, as a set of internal values versus external perceptions of social belonging, may relate to motivation in distinct ways. Utilizing a sample of 600 African American and Latino adolescents (43%…

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;…

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…

Educational TV has been consistently linked to children's learning. In this research, educational TV characteristics were identified, coded, and tested for their influence on children's program-specific comprehension and vocabulary outcomes. Study 1 details a content analysis of TV features including a program's macrostructure (i.e., narrative or…

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…

Factors that influence the incidence of utilization deficiencies and other recall/strategy-use patterns on a strategic memory task were evaluated in two hundred and fourteen 7- and 9-year-old children. Both utilization deficiencies and the incidence of children showing increases in both recall and strategy use over phases were more likely to be…

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;…
