Detection and responding to a player's affect are important for serious games. A method for this purpose was tested within Chem-o-crypt, a game that teaches chemical equation balancing. The game automatically detects boredom, flow, and frustration using the Affdex SDK from Affectiva. The sensed affective state is then used to adapt the game play…

This experimental study investigated the effects of the use of two versions of a pedagogical agent named personal instructing agent (PIA) on the mathematics performance of students. The first version exhibits synthetic facial expressions while the second version does not exhibit facial expression (i.e., neutral facial expression). Two groups of…

This study attempted to determine the influence of prior knowledge in mathematics of students on learner-interface interactions in a learning-by-teaching intelligent tutoring system. One hundred thirty-nine high school students answered a pretest (i.e., the prior knowledge in mathematics) and a posttest. In between the pretest and posttest, they…

The purpose of the two experiments was to investigate the potential effects of different types of visualizations and self-explanation prompts on learning human cardiovascular system in a multimedia environment. In Experiments 1 and 2, 70 and 44 college students were randomly assigned to one of the four conditions in a 2 × 2 factorial design with…

Sixty-two high-school biology students, paired heterogeneously based on prior knowledge, learned about genetic using GenScope, a computer-based learning environment (CBLE), over four 90-minute class periods. Differences between low and high prior knowledge students emerged with convergence of verbal process data and pre- and post-test product…

Investigates the benefits of using culturally responsive reading material and a computer-based learning environment in literacy instruction. Describes a study of low socioeconomic status first through fourth grade African American children that tested two computer programs that use prior knowledge as scaffolds for early literacy instruction.…

This study investigated factors affecting second/foreign language (L2) reading comprehension in a hypermedia environment within the theoretical framework of dual coding and cognitive load theories, and interactive models of L2 reading. The independent variables were reading ability, topic interest, prior topical knowledge, and the number of times…

Describes study of students at a two-year community college that was conducted to examine descriptive references to a computer for differences in interactive styles when reporting success and failure experiences while using a computer for word processing. Differences that relate to gender and computer experience are also analyzed. (18 references)…

This study compared the use of an animated pedagogical agent (agent) with an electronic arrow and voice narration (arrow and voice) in a multimedia learning environment where 74 college level English as a Second Language (ESL) students learned English relative clauses. No significant differences in learning or performance were found between the…

Describes development of a causal model to test effects of scholastic ability, computing attitudes, and computing background of university undergraduates on use of a computer-assisted instructional system, PLATO-LDEC; on attitudes toward PLATO-LDEC; on computing attitudes after students' PLATO-LDEC experience; and on course grade. (Author/MBR)

Describes a study of Australian secondary school students that identified the conditions and individual characteristics that would best support learners' acceptance of control within hypermedia, based on evidence from the learner control literature. Investigated effects of prior domain knowledge, learning activity structure, ability, and attitudes…

Describes study of Israeli secondary school students that was conducted to determine the extent to which gender and prior computer exposure affect students' attitudes toward computers prior to computer instruction in school. An attitude questionnaire designed to measure affective and cognitive attitudes toward computers is described, and results…

This experimental study explored whether, and to what extent, differences in gender and experience with word processing affect how students perceive their classroom environment in high school writing classes. Treatment of experimental and control groups is described, and the classroom environment questionnaire for the experimental…

Children from non-English-speaking homes are doubly disadvantaged when learning English in school. They enter school with less prior knowledge of English sounds, word meanings, and sentence structure, and they get little or no reinforcement of their learning outside of the classroom. This article compares the classroom standard practice of…
