In a series of experiments, we tested a recently proposed hypothesis stating that the degree of alignment between the form of a mental representation resulting from learning with a particular visualization format and the specific requirements of a learning task determines learning performance (task-appropriateness). Groups of participants were…

In this study, we meta-analyzed empirical research of the effectiveness of intelligent tutoring systems (ITS) on K-12 students' mathematical learning. A total of 26 reports containing 34 independent samples met study inclusion criteria. The reports appeared between 1997 and 2010. The majority of included studies compared the effectiveness of ITS…

Students (n = 797) from 36 4th-grade classrooms were taught the control of variables strategy for designing experiments. In the instruct condition, classes were taught in an interactive lecture format. In the manipulate condition, students worked in groups to design and run experiments to determine the effects of four variables. In the both…

This study assessed the effects of small-group tutoring with and without validated classroom instruction on at-risk students' math problem solving. Stratifying within schools, 119 3rd-grade classes were randomly assigned to conventional or validated problem-solving instruction (Hot Math, schema-broadening instruction). Students identified as at…

College students viewed a short multimedia PowerPoint presentation consisting of 16 narrated slides explaining lightning formation (Experiment 1) or 8 narrated slides explaining how a car's braking system works (Experiment 2). Each slide appeared for approximately 8-10 s and contained a diagram along with 1-2 sentences of narration spoken in a…

Do students learn more deeply from a passage when they attempt to construct their own graphic organizers (i.e., learning by doing) than when graphic organizers are provided (i.e., learning by viewing)? In 3 experiments, learners were tested on retention and transfer after reading a passage with author-provided graphic organizers or when asked to…

Students were randomly assigned to study an instructional program by constructed responding or by reading. Level of prior attainment was ascertained by pretest scores. Interaction was found between prior achievement and instructional support. Constructed responding was especially beneficial for students with low pretest scores. (BJG)

Two experiments explored the integration of animated agents into multimedia environments in the context of R. E. Mayer's (2001) cognitive theory of multimedia learning. The spoken-narration-only condition outperformed other conditions, with no differences between printed text and printed text with spoken narration. (Author)

Fourteen groups of college students were shown a 30-minute film, introducing an assembly kit, in one of seven versions of visual-narrative overlap. For best associative recall of object names, results indicated visuals should be presented before or simultaneously with text in dual-media presentations. (Author/BS)

Three studies investigated whether and under what conditions the addition of on-screen text would facilitate the learning of a narrated scientific multimedia explanation. The overall pattern of results can be explained by a dual-processing model of working memory, which has implications for the design of multimedia instruction. (Author)

Sixth graders (n=124) were tested for their perceptions of self-efficacy with print and TV, perceived media realism, and attributions of failure and success with each medium. The amount of invested mental effort (AIME) and achievement were measured. The roles of a priori perceptions and AIME in learning are discussed. (Author/BS)

Eighty-eight seventh grade students were randomly assigned to mastery or nonmastery approaches to learning four hierarchical chapters about sailing. The price of increased achievement benefits of group-based mastery learning seems to be increased time costs of (1) extra remedial time and (2) "wasted time" of faster learners. (Author/PN)

In order to examine the influence of interactive media on children's story memory, first-grade children experienced a computer-based story in one of four presentation modes, two of which were interactive. In the interaction groups, there was no relation between the amount of interaction with the story and subsequent memory. (Author)

An adult read to 12 children from a regular paper book. Twenty-four children explored a similar electronic book. For half of this group, the electronic book was with and for half without restrictions on games. Regular book format was more supportive of learning story content and phrasing; both formats supported internalization of features of…
