Presents a study to determine differences in effectiveness of computer-assisted instruction (CAI) compared to traditional instruction of general biology students (n=54) for units on photosynthesis and introductory genetics and to assess students attitudes toward CAI. Results indicate CAI tutorials are no more or less effective in promoting student…

Discussion of learning styles and learner control focuses on a study of college students that paired field-dependent and field-independent learning styles with different instructional control treatments. The use of interactive video lessons and a printed self-study guide is described, and treatments for the experimental and control groups are…

Discussion of computer-based instruction and animation focuses on a study of undergraduates that investigated the effects of two computer-based instructional strategies, visual display and feedback type, on teaching how to troubleshoot electronic circuits. Time spent on various components of the program is also examined. (35 references) (LRW)

Describes a study that investigated the effects of using different forms of computer-based feedback on high school students' learning of science material. Hypotheses tested are discussed, five feedback conditions are described, posttests are explained, and results are discussed in terms of the information processing effects of different feedback…

Compares conversational styles of intermediate and advanced learners of English as a Second Language in language proficiency interviews. The article describes differences in amount of talk and rate of speaking, extent of context dependence and ability to construct and sustain narratives, but not in frequency of initiation of new topics nor…

Examines the generalizability of claims about the implicit learning of artificial grammars to the context of adult second-language acquisition (SLA). Specifically addressed are claims that implicit learning is more effective than explicit learning when the stimulus domain is complex, and explicit learning of simple and complex stimulus domains is…

Describes a study conducted at the C. W. Post Campus of Long Island University (New York) that measured librarians' opinions of and attitudes toward a self-paced bibliographic instruction workbook. Survey results were compared for librarians who used the self-paced approach and those who followed a traditional approach. (Contains six references.)…

Two hundred-fifty African American college students from two predominantly White institutions (PWIs) and two historically Black colleges and universities (HBCUs) were administered the Non-Cognitive Questionnaire-Revised (NCQ-R) and the Multidimensional Inventory of Black Identity (MIBI) to determine which psychosocial indices best predicted…

The rise in suicide by African Americans in the United States is directly attributable to the dramatic, nearly three-fold increase in suicide rates of African American males. Gibbs (1997) hypothesized high social support, religiosity, and southern residence are protective factors against suicidality for Black people. This hypothesis was tested…

Background: Deficits in executive functioning are supposed to have a predisposing influence on impulsive or aggressive behaviour. We tested the hypothesis that oppositional-defiant disorder (ODD) children with or without attention deficit hyperactivity disorder (ADHD) have problems in executive functioning. Method: Seventy-seven 7- to 12-year-old…

A review of the literature in science education shows that most students have difficulties in hypothetico-deductive reasoning. The author's objective in this study was to investigate the abilities of high school teachers and university teachers to understand the difference between the terms "hypothesis" and "prediction" in the…

The main hypotheses addressed in the research were (1) whether imprecision in the phonological representations of lexical items underlies the impaired expressive naming abilities of disabled readers, and (2) whether weak verbal memory might mediate the relationship between naming and reading skills. From samples of 93 first graders and 67 fourth…

Infants under six months are able to discriminate native and non-native consonant contrasts equally well, but as they learn the phonological systems of their native language, this ability declines. Current explanations of this phenomenon agree that the decline in discrimination ability is linked to the formation of native-language phonemic…

An open social systems model is used to frame and test a series of hypotheses. The socioeconomic status of the environment and four internal system elements (structure, individual, culture, politics) of the school are used to explain two sets of school outcomes: student achievement and teachers' assessments of overall school effectiveness. A…

Inquiry training is a powerful teaching model for principals to know and teachers to implement. It is designed to teach students to engage in causal reasoning and to become more fluent and precise in asking questions. Further, inquiry training helps learners build concepts and form and test hypotheses in all curriculum areas. The current emphasis…
