Student attitudes toward science-technology-society resulting from visitation to a science-technology museum

Are student attitudes toward science-technology-society (TSS) affected by visitation to science-technology museums? The purpose of this study was to determine whether such visitations affected student STS attitudes, and in what ways particular factors of the visitation impacted these attitudes. Factors examined included prior classroom experience with STS, instructional methodology employed by teachers, grade level, socioeconomic status, school type (public or private), and gender. The subjects involved in the study were 194 Kansas students in grades 6-8, and their 13 classroom teachers. Data were collected via a pretest-posttest control group design by using study-specific questionnaires and the Moore-Sutman Scientific Attitudes Inventory. Results indicated that significant differences in attitudes were present between visiting and nonvisiting students and between grade levels. No significant differences were found between other factors. One possible conclusion is that sound pedagogy should be used prior to and during museum visitations as well as in the classroom.

Maximum Dynamic Strength,Relative Dynamic Endurance,and Their Relationships

Abstract

Nine males and nine females were used as subjects to test the null hypothesis that there would be no significant differences between the performance of college age males and females on three motor tasks. Star tracing, tapping, and rotary pursuit were the tasks used under two conditions: (a) while looking at a mirror that would cause a reversal effect, and (b) under standard conditions without looking at a mirror. Results revealed no differences between males and females on the tasks performed without a mirror. However, the females performed significantly better on the same tasks while looking at a mirror.     

Placement and frequency of powerless talk and impression formation

Study One examined the influence of initial use of hesitations and hedges on evaluations of witnesses and their persuasiveness in a budget hearing context. Results indicate that the negative attributions generated by the use of powerless language cannot be overcome by subsequent use of powerful talk. Study Two examined the relationship between the frequency of powerless language use and impression formation. For award/character and dynamism a perceptual threshold appeared to operate. The results of both studies suggest that auditors are very sensitive to the influence of powerless talk in formal settings.     

What Is Measured Is Treasured: The Impact of the No Child Left Behind Act on Nonassessed Subjects

In this article, the author reports the results of a national survey taken by state assessment directors on the impact of No Child Left Behind on nonassessed subjects between the years 2001-5. Results indicate that during this time, statewide assessment of science and writing increased whereas it decreased in the social studies, arts and humanities, listening, and technology and computers. Four themes emerged when survey takers queried participants about the impact of No Child Left Behind on nonassessed subject areas. First, reduction of resources and time for nontested subject areas was evident. Second, curriculum integration of nontested subject areas into the tested subjects increased. Third, alignment of curriculum and assessment with state standards increased. Fourth, several state assessment directors relayed they observed no impact.
