Management of science classroom tasks and effects on students' learning opportunities

This study examined the work that students completed during six or seven week units of instruction in four different science classes. The purpose of the study was to assess the kinds of learning opportunities students had as they dealt with science content and the problems teachers faced in managing different kinds of assignments, particularly assignments that required students to use higher level cognitive operations. Management strategies associated with these assignments are described and the effects of these strategies are considered.     

Subject matter competence and the recruitment and retention of secondary science teachers

The purpose of this study was to investigate the relationship of subject matter knowledge in science and the patterns of entering, leaving, and remaining in the teaching profession among college graduates trained to be science teachers. To do this, National Teachers Examination (NTE) Biology and General Science test scores served as the proxy for science subject matter knowledge for a sample of 83 individuals initially certified to teach science in North Carolina during a 4-year period of time. The career patterns of these individuals as science teachers were documented and their work status was identified as nonrecruits, defectors, or career teachers. Using maximum likelihood logistical regression (MLOGIT) analysis, the relationship between career status (the dependent variable) and knowledge of science, race, gender, and the race and status (public or private) of the college from which they graduated was investigated. Of the 83 individuals in the analysis, 30 (36.1%) were identified as nonrecruits, 31 (37.3%) as defectors, and 22 (26.5%) as career teachers. Science subject matter knowledge was found to have a significant (p = .01) effect on the likelihood of being a nonrecruit versus a career teacher. The magnitude of this effect was also important, with the likelihood of being a nonrecruit increasing 120% for every 100-point increase in score on the NTE Biology and General Science tests. Science subject matter knowledge also had a significant effect (p = .05) on the likelihood of being a defector versus a career teacher, with the likelihood increasing 80% for every 100-point increase in NTE Biology and General Science scores. No other significant relationships were found.     

Expand,Humanize, Simplify: An Interview with Sandy Berman

In this interview, Sanford (“Sandy”) Berman discusses his career and his efforts to promote responsive, user-friendly cataloging practices over uncritical deference to prevailing standards. Topics covered include his work at Hennepin County Library, his thoughts on the campaign to change the subject heading “Illegal aliens,” his ongoing practice of proposing new Library of Congress Subject Headings, and his relationship with the Library of Congress.     

Parenting Styles, Adolescents' Attributions, and Educational Outcomes in Nine Heterogeneous High Schools

This article examined the contemporaneous and predictive relations between parenting styles, adolescents' attributions, and 4 educational outcomes. Data were collected from adolescents attending 6 high schools in California and 3 high schools in Wisconsin during the 1987–1988 and 1988–1989 school years. The results of path analyses partially confirmed the central hypotheses. Adolescents who perceived their parents as being nonauthoritative were more likely than their peers to attribute achievement outcomes to external causes or to low ability. Furthermore, the higher the proportion of dysfunctional attributions made for academic successes and failures, the lower the levels of classroom engagement and homework 1 year later. Although adolescents' attributional style provided a bridge between parenting style and 2 educational outcomes, it did not fully explain the impact of parenting on those outcomes. Additional analyses within gender and ethnic subgroups reinforced the overall pattern of findings observed within the entire sample.
