We carried out 4 semester-long studies of student performance in a college research methods course (total N = 588). Two sections of it were taught each semester with systematic and controlled differences between them. Key manipulations were repeated (with some variation) across the 4 terms, allowing assessment of replicability of effects.…

When people attribute human characteristics to nonhuman objects they are amenable to anthropomorphism. For example, human faces or the insertion of personalized labels are found to trigger anthropomorphism. Two studies examine the effects of these features when included in decorative pictures in multimedia learning materials. In a first…

Test-potentiated learning occurs when testing renders a subsequent study period more effective than it would have been without an intervening test. We examined whether testing only a subset of material from a multimedia lesson would potentiate the restudy of both tested and untested material. In Experiments 1a and 1b, participants studied a…

Does correctly answering a test question about a multiterm fact enhance memory for the entire fact? We explored that issue in 4 experiments. Subjects first studied Advanced Placement History or Biology facts. Half of those facts were then restudied, whereas the remainder were tested using "5 W" (i.e., "who, what, when, where",…

In spite of its potential for learning, and in particular knowledge revision, argumentation on science concepts is neither easily elicited nor easily sustained. Students may feel uneasy critiquing and being critiqued, especially on complex science topics. We report on a controlled study that tested the role of 2 potential factors that may either…

We investigated direct and indirect effects of component skills on writing (DIEW) using data from 193 children in Grade 1. In this model, working memory was hypothesized to be a foundational cognitive ability for language and cognitive skills as well as transcription skills, which, in turn, contribute to writing. Foundational oral language skills…

The current study models reader, item, and word contributions to the lexical representations of 39 morphologically complex words for 172 middle school students using a crossed random-effects item response model with multiple outcomes. We report 3 findings. First, results suggest that lexical representations can be characterized by separate but…

A commonly held belief among educators, researchers, and students is that high-quality texts are easier to read than low-quality texts, as they contain more engaging narrative and story-like elements. Interestingly, these assumptions have typically failed to be supported by the literature on writing. Previous research suggests that higher quality…

This study examined predictors of the quality of parental homework involvement and reciprocal relations between the quality of parental homework involvement and students' reading achievement and academic functioning in a reading-intensive subject (German). Data from 2,830 students in nonacademic tracks and their parents who were surveyed in both…

Although students' motivational frameworks (entity vs. incremental) have been linked to academic achievement, little is known about how early this link emerges and how motivational frameworks develop in the first place. In a year-long study (student N = 424, Teacher N = 58), we found that, as early as 1st and 2nd grade, children who endorsed an…

Using a cognitive load theory approach, we investigated the effects of speaker variability when individuals are learning to understand English as a foreign language (EFL) spoken by foreign-accented speakers. The use of multiple, Indian-accented speakers was compared to that of a single speaker for Chinese EFL learners with a higher or lower…
