Assessment of aerobic endurance: a comparison between CD-ROM and laboratory-based instruction

Traditional approaches to teaching exercise physiology are costly in terms of staff time and consumable expenses. Ethical considerations, large student numbers and availability of technical expertise magnify the delivery problems. In an attempt to overcome these problems, a CD-ROM version of a basic course in exercise physiology was designed and delivered to a group of undergraduate sport and exercise science students. It simulated five tests of aerobic endurance which are traditionally taught using laboratory methods. A controlled experiment was conducted to compare the two delivery methods, as part of an independent, formative evaluation. Although there were equal knowledge gains and the CD-ROM design and content were well rated by students who used it, this approach has engendered less student interaction, commitment to wider reading and in-depth understanding. Tutorials and other approaches designed to promote more active learning are now being introduced to accompany the use of the CD-ROM.     

Characteristics of the Early Intervention Workforce: An Indiana Perspective

In preparation for implementation of Part H of P.L. 99-457, the Indiana early intervention workforce was surveyed to determine the current status of the workforce and identify implications for policy making. A sample of 837 respondents generated information about the types of personnel providing services, their qualifications, compensation, and longevity in the field. Turnover rates for the personnel categories surveyed were also obtained. Education and licensure for teachers and aides showed considerable variation, with some personnel having training in areas related to early intervention and many with training in unrelated areas. Striking differences were seen in compensation favoring public school personnel over personnel employed in other types of agencies. Personnel turnover rates were high, averaging 30%. The data indicate the need for early intervention training programs and equitable compensation of trained personnel if Indiana, and presumably other states, are to meet the mandate of P.L. 99-457, Part H. The most critical needs are to develop strategies to attract, train, and support specialized early intervention personnel from a wide variety of disciplines.     

School evolution: scientist-practitioner educators creating optimal learning environments for all students

Similarities and differences between discursive practitioners and scientist-practitioners are discussed in reference to a variety of issues. The scientist-practitioner's approach to generating and evaluating new knowledge is illustrated with two partnerships: (a) between the University of Washington Multidisciplinary Learning Disability Center and a school district (at-risk first graders in the Los Angeles Unified School District) and (b) between the University of Washington Literacy Trek Project and a local school (at-risk second graders in Seattle public schools). Both partnerships involved mostly children who were English language learners. These partnerships also illustrated how Vygotsky's approach to fostering cognitive development through social interaction can be integrated with that of his pupil Luria, who assessed the neuropsychological processes of the individual mind/brain. The most effective instruction for school-age children, who exhibit biological and cultural diversity, takes into account individual and social-cultural variables.     

Young Children''s Understanding of Other People''s Feelings and Beliefs: Individual Differences and Their Antecedents

Individual differences in young children's understanding of others' feelings and in their ability to explain human action in terms of beliefs, and the earlier correlates of these differences, were studied with 50 children observed at home with mother and sibling at 33 months, then tested at 40 months on affective-labeling, perspective-taking, and false-belief tasks. Individual differences in social understanding were marked; a third of the children offered explanations of actions in terms of false belief, though few predicted actions on the basis of beliefs. These differences were associated with participation in family discourse about feelings and causality 7 months earlier, verbal fluency of mother and child, and cooperative interaction with the sibling. Differences in understanding feelings were also associated with the discourse measures, the quality of mother-sibling interaction, SES, and gender, with girls more successful than boys. The results support the view that discourse about the social world may in part mediate the key conceptual advances reflected in the social cognition tasks; interaction between child and sibling and the relationships between other family members are also implicated in the growth of social understanding.     

A procedure for determining the level of abstraction of science reading material

The objectives of this study were to develop a method for scoring the level of abstraction (LOA) of science reading material and explore its relationship with other methods for assessing curriculum materials. LOA is defined as the ratio of the nonconcrete concepts to the total number of concepts in a written passage expressed as a percent. Using passages taken from life, earth, and physical science textbooks written at three different levels, data were collected to obtain preliminary agreement from science educators in the classification of concepts, determine interscorer reliability, and compare student and passage variables. Participants consisted of 24 science educators, 60 science teachers from elementary, middle, and high schools, and 425 urban students in Grades 5, 7, and 10. Instruments used were (a) the procedure to determine level of abstraction developed in this study, (b) the cloze procedure, and (c) “Reading Level: Programs for Teachers.” No significant correlations were found between (a) passage LOA and passage readability level, (b) student cloze scores and passage LOA, (c) passage LOA and teacher prediction of student success, and (d) student cloze scores and passage readability level. However, the lack of significant correlations between LOA and cloze scores combined with the fact that the LOA is based upon deep structure rather than surface structure of written material indicate the possible uniqueness of the LOA and highlight the importance of further investigation of the LOA in its relationship to student comprehension of written material.     

Gender equality in German universities: vernacularising the battle for the best brains

We examine how global pressures for competitiveness and gender equality have merged into a discourse of ‘inclusive excellence’ in the twenty-first century and shaped three recent German higher education programmes. After placing these programmes in the larger discourse about gender inequalities, we focus on how they adapt current global concerns about both being ‘the best’ and increasing ‘gender equality’ in locally specific ways, a process called vernacularisation. German equality advocates used ‘meeting international standards’ as leverage, drew on self-governance norms among universities, used formal gender plans as mechanisms to direct change, and set up competition to legitimate intervention. This specific incremental policy path for increasing women's status in German universities also mobilised the national funding agency and local gender equality officers as key actors, and placed particular emphasis on family friendliness as the expression of organisational commitment to gender equality.     

Mutual influence of marital conflict and children's behavior problems: shared and nonshared family risks

This within-family, longitudinal study including biological and stepfamilies investigated mutual influences between marital conflict and children's behavior problems. Children (4 to 17 years; N=296) residing in 127 families drawn from a general population study were investigated at Time 1 and again 2 years later. These nested data were analyzed using multilevel modeling, controlling for previous child behavior or marital conflict. Marital conflict about children predicted change in children's behavior. Children's behavior also predicted an increase in marital conflict, particularly in stepfamilies. Differences between siblings in exposure to conflict and the extent to which siblings were a source of argument increased more in stepfamilies than in biological families. Boys were exposed to more conflict over time than were girls.     

Mixed-Age Interactions in Family Child Care

Preschool-age children's experiences within the mixed-age setting of family child care homes and the influences of these experiences on development were examined. Development variables included social and cognitive play, and receptive and expressive language. Consistent with Vygotsky's developmental theory, children's interactions with mixed-age peers were more powerful predictors of development than the mere availability of mixed-age peers. Interactions with older peers were associated with more complex cognitive play behaviors. Interactions with younger and same-age peers were associated with less complex social and cognitive play and lower receptive language scores. Characteristics of the child care setting appeared to moderate children's behavior in the mixed-age environment. Children in higher quality family child care homes with responsive caregivers were less likely to interact with younger children. No evidence was found of different developmental outcomes across developmental domains for older versus younger children.
