Effects of response options on the mathematics performance of secondary students with emotional or behavioral disorders

ABSTRACT

This study examined the effects of three response options (traditional responding, response cards, and response systems) on the mathematics performance, participation, and time on-task of secondary students with emotional or behavioral disorders (EBD). A three-way crossover design was utilized to evaluate the efficacy of response options in secondary mathematics classrooms. Thirty-three students with EBD attending an urban high school and their teachers served as participants. Results indicated that the use of response cards (white boards) or response systems (ActivResponders) significantly increased students’ mathematics performance, participation, and time on-task when compared to traditional responding. Further, the use of response cards resulted in significant increases in performance and response accuracy over the increases found when using response systems. Social validity data indicated that students and teachers felt they benefited from the use of response cards and systems. Limitations, discussions, and implications for practice and future research are presented.     

Motivational Preconditions for Girls Gifted and Highly Gifted in Physics

During their socialisation process, many girls gifted in physics acquire a reality construction inconsistent with their objectively measurable competencies. In comparison to boys they rate their action and problem solving competencies unrealistically low, which results, for example, in extremely low participation rates in scientific and technical studies and professions. For this reason differences in motivation and self‐related cognitions become the focus of interest in explaining achievement differences. The present study was carried out prior to initial physics instruction. Students in the 7th grade of the German Gymnasium (243 girls and 282 boys) were divided according to their KFT 4‐13+ results into “average”, “gifted” or “highly gifted groups”. Prior to commencement of physics instruction, boys in general, as well as gifted male and female students, already possessed more knowledge of physics and more favourable motivation for the subject than girls or male and female students of average ability. In addition, domain specific measures and self‐related cognitions were evaluated in accordance with Dweck's model of achievement motivation.     

A case for culturally relevant science education in the summer for African American youth

Abstract

This article focuses on the impact of culturally relevant teaching and learning during a summer enrichment program for high school students. Culturally relevant science instruction and curriculum helped students to foster a more positive interest in science and STEM careers as it provided students the opportunity to do science in meaningful and relevant ways. Students were able to see themselves represented in the curriculum and recognized their own strengths; as a result, they were more validated and affirmed in and transformed by, their learning. We use this case to warrant increased support for summer learning programs focused on providing African American youth with access to high quality, culturally relevant/responsive science education.     

The Communicative Construction of Involuntary Membership

This study expands conceptions of organizational membership by examining individuals whose relationships with their organizations are traditionally characterized as involuntary in nature. Data from inmates and prison employees in four U.S. and Norwegian correctional institutions was examined using structuration theory as an emergent interpretive lens, and five primary ways in which involuntary membership is constructed in communication are identified: physical environment, mobility, relationships, engagement, and body. These facets are presented as the foundation of a continuum-based theoretical perspective on (in)voluntary membership and are discussed for their applicability to future research and theorizing across organizational communication studies.     

添加剂和升温速度对Si_3N_4陶瓷显微结构的影响

本文研究了添加剂种类和升温速度对气压烧结Si_3N_4陶瓷显微结构的影响。结果表明:只加入Sc_2O_3,升温速度对β—Si_3N_4晶体生长影响甚微。同时加入Sc_2O_3和ZrO_2,升温速度对β—Si_3N_4的晶体形貌影响显著。慢速升温可有效地提高β-Si_3N_4晶体的长径比,并形成长径比大的大晶体镶嵌在细小晶体群之中的显微结构。     

Technical possibilities and economic prospects for coal refining

International preoccupation with the oil crisis has tended to concern itself mainly with the economic aspects and this has obscured the fact that, regardless of price, the world's oil reserves are rapidly becoming exhausted. Alter-native sources of energy are, therefore, not merely desirable but essential and much attention is now being directed to the more effective use of coal, reserves of which are still very substantial. This article reviews—in both practical and economic terms—current technology for the refining of coal and the prospects it offers for the future.     

Sexual Content in Music and Its Relation to Sexual Attitudes and Behaviors among Consumers: A Meta-Analytic Review

While previous research has documented a relation between sexual content in music and the sexual attitudes and behaviors of consumers, to date, there are no meta-analytic reviews of the literature, making our meta-analysis the first in this area. Results from 26 studies indicated that sexual content in music had a significant effect on sexual attitudes and behaviors, with both music format and genre being significant contributors. Additionally, participant ethnicity, sex, age, location, and study design were found to be significant moderators. Theoretical implications are discussed, along with suggestions for future research.
