Based on current theories of chemistry learning, this study intends to test a hypothesis that computer modeling enhanced hands-on chemistry laboratories are more effective than hands-on laboratories or computer modeling laboratories alone in facilitating high school students' understanding of chemistry concepts. Thirty-three high school chemistry…

The "computers are social actors" paradigm asserts that human-to-computer interactions are fundamentally social responses. Earlier research has shown that effective management of the social presence in user interface design can improve user engagement and motivation. Much of this research has focused on adult subjects. This study…

In our match towards scientific and technological advancement, we need nothing short of good performance in mathematics at all levels of schooling. In an effort to achieve this, this study investigated the impact of motivation on students' school academic achievement in mathematics in secondary schools using motivation for academic preference…

A pre-postassessment, single-subject, pilot study was implemented, testing the hypothesis that positive behavior support (PBS) would improve family quality-of-life outcomes by reducing parental stress and challenging behaviors of preschool children who are culturally and linguistically diverse and reside in urban, disadvantaged communities. Six…

This study examined whether sociocontextual and sociocognitive variables explained the math/science goals of 409 Mexican American youth using a modified version of R. W. Lent, S. D. Brown, and G. Hackett's (1994) social cognitive career theory. Results from structural equation modeling indicated that the hypothesized model explained a significant…

This article focuses on the empirical effects of cognitive differentiation and persuasive skills on transformational, transaction, and laissez-faire leadership. Subjects (N = 294) completed measures of independent and dependent variables. Findings confirmed prior findings, however some findings reflected differences. Cognitive differentiation was…

The main objective of this study is to explore the coping behaviours of Israeli continuing education students who combine work and academic studies. Multi-level analyses revealed that: (1) perceived academic stress is determined by academic load and perceived work stress by workload; (2) coping strategies are related to an array of perceived…

The purpose of this longitudinal study was to examine associations among background characteristics, commitment levels, institutional involvements, and persistence for male and female university students. Data were collected from college records and surveys completed by 316 university freshmen at the beginning of and 10 weeks into the 1984 fall…

The contribution of decentration as an underlying component of discrimination learning and discrimination shift behavior was investigated in this study. In addition, the effect of verbal labeling and the relationship of academic achievement to discrimination learning and decentration was considered. The subjects were 120 first grade students who…

By examining relationships between a host of national policy, domestic economic, media system, and media infrastructure factors, a study assesses possible predictors for videotape cassette recorder (VCR) penetration across 63 countries. Overall statistical results generated through hypothesis testing indicated that these factors were relatively…

In order to determine the relationship of the socioeconomic variable sets of education, general characteristics, and income and housing to geographic variations in the collection size of academic and public libraries in the United States, data for the 50 largest Standard Metropolitan Statistical Areas (SMSAs) are analyzed using frequency…

A study was conducted to investigate the comprehensibility of microcomputer-generated color graphics that are displayed on monochromatic monitors. Subjects were 64 second, third, and fourth graders who were randomly assigned to one of two conditions. Children in the first treatment were asked to identify, on a monochrome monitor, a figure that was…

This study was conducted to determine whether the filmic coding elements of split screen, slow motion, generated line cues, the zoom of a camera, and rotation could aid in the development of the Euclidean space concepts of horizontality and verticality, and to explore presence and development of spatial skills involving these two concepts in…
