This study was designed to measure some effects of supplemental instruction in chemistry. Supplemental instruction is a peer-led cooperative learning program that encourages students to develop conceptual understanding by articulating both understandings and misconceptions in a think-aloud fashion. Supplemental instruction was offered three hours weekly outside of class and lab time for students in four classes of General Organic and Biological Chemistry. Over a two-year period 108 students volunteered to participate in this program; 45 students did not participate. As measured by final grades in chemistry and responses to a questionnaire, supplemental instruction was effective in increasing students' achievement in chemistry. Further research is needed to determine the in-depth effects of supplemental instruction on students' learning, problem solving, and self-esteem. 相似文献

The issue of sex discrimination in faculty employment has become a prominent legal and political concern, necessitating the development of objective empirical methods to determine the existence of patterns of discriminatory treatment. In this study, regression techniques are employed to apply the equal pay for equal work interpretation of the fair employment doctrine. Specifically, faculty promotion and salary policies at the University of Texas at Austin are analyzed to determine whether male and female faculty members are rewarded equally for equal academic qualifications and performances. This regression analysis tends to support the discrimination hypothesis with respect to both promotion and salary policies. 相似文献

Formative evaluation in instructional design is widely advocated as a means to improve instructional materials through tryouts with learners and experts and revision based on this feedback. Research on formative evaluation has sought to prove its effectiveness and to provide guidance as to which methods of collecting feedback and which sources of feedback are most effective in improving learning. It is difficult to determine from the research whether aspects of tryout or of revision are responsible for improved learning. This paper describes a systematic investigation of both tryout and revision to more clearly determine the influence of different formative evaluation participants (experts, learners and revisers) on the improvement of learning from written instructional materials.It was found that revised versions incorporating learner feedback had the most impact on improving learning from the materials. It was also found that revisers have a far more powerful impact on formative evaluation outcomes than was previously supposed, in terms of how they mediate and incorporate the feedback they are given. The results refute contentions that any revision is better than none since versions revised without learner feedback did not improve learning. Implications are discussed. 相似文献

We used the Canadian data from the Cross-National Survey on Health Behaviors in School-Aged Children (HBSC) to examine the
effects of school experiences on substance use among Canadian students, with seven measures on use of illegal drugs, alcohol,
and tobacco. Multilevel data analyses with students nested within schools indicated an obvious increasing trend of substance
use in each and every measure across grade levels (Grades 6 to 10). Students with low perception of their academic status
and students from single-parent households were most likely to use alcohol and tobacco. Female students were more likely to
use tobacco than male students. In comparison to student characteristics, substance use was much more strongly related to
school experiences. Characteristics of schools in which students' substance use was minor can be described as (a) positive
circle of friends, (b) positive sense of belonging to school, and (c) positive parental support. The circle of friends was
the most important school-level variable that affected students' substance use across grade levels (Grades 6 to 10).

Specifying learning outcomes (LOs) in higher education as part of the European Qualification Framework (EQF) has resulted in a variety of experiences in the national contexts of England and Norway, as well as in different institutional and disciplinary settings. This article contributes to a contextualised understanding of the kind of management tools that higher education learning outcomes (HELOs) are, based on a conceptually‐informed comparative empirical analysis. The comparison is based on two types of disciplines (the humanities and STEM) in two national contexts (Norway and England) at two research‐intensive universities in each country. These settings offer an opportunity to look for evidence – inspired by public administration literature – as to whether HELOs have some specific characteristics as management tools. HELOs share the characteristics that afflict most reform policies – that of ambiguity and the potential of being shaped by a number of circumstantial factors. Higher education institutions are highly dependent on, and embedded in, multiple relationships to the environment. Hence, as decision making structures, they are ‘penetrated’ and influenced in ways that are likely to vary across countries, types of institutions and academic disciplines. Because institutions and disciplinary groups are embedded in different policy (varying degrees and forms of state steering and policy implementation) and organisational environments (different degrees and forms of hierarchical leadership, managerial control, and autonomy) and different disciplines (different perceptions of scientific‐, professional‐, educational mission, and relationships to external stakeholders) they also constitute different organisational spaces for participation and engagement in shaping and using HELOs. 相似文献
