Engaging Undergraduates in Science Research: Not Just About Faculty Willingness     

Eagan MK  Sharkness J  Hurtado S  Mosqueda CM  Chang MJ 《Research in higher education》2011,52(2):151-177

Despite the many benefits of involving undergraduates in research and the growing number of undergraduate research programs, few scholars have investigated the factors that affect faculty members’ decisions to involve undergraduates in their research projects. We investigated the individual factors and institutional contexts that predict faculty members’ likelihood of engaging undergraduates in their research project(s). Using data from the Higher Education Research Institute’s 2007–2008 Faculty Survey, we employ hierarchical generalized linear modeling to analyze data from 4,832 science, technology, engineering, and mathematics (STEM) faculty across 194 institutions to examine how organizational citizenship behavior theory and social exchange theory relate to mentoring students in research. Key findings show that faculty who work in the life sciences and those who receive government funding for their research are more likely to involve undergraduates in their research project(s). In addition, faculty at liberal arts or historically Black colleges are significantly more likely to involve undergraduate students in research. Implications for advancing undergraduate research opportunities are discussed.  相似文献

Effect of a semi electro-mechanical engine valve on performance and emissions in a single cylinder spark ignited engine     

Bülent 《浙江大学学报(A卷英文版)》2010,11(2):106-114

In this study, an electro-mechanical valve （EMV） system for the intake valve ofa fottr stroke, single cylinder, overhead valve and spark ignition （SI） engine was designed and constructed. An engine with the EMV system and a standard engine were tested to observe the effects of the EMV on engine performance and emissions at different speeds under full load. The EMV engine showed improved engine power, engine torque and break specific fuel consumption （BSFC）. A 66% decrease in CO emissions was also obtained with the EMV system, but hydrocarbons （HC） and NOx emissions increased by 12% and 13% respectively.  相似文献   

Effectiveness of Spanish intervention for first-grade English language learners at risk for reading difficulties   总被引：1，自引：0，他引：1  

Vaughn S  Linan-Thompson S  Mathes PG  Cirino PT  Carlson CD  Pollard-Durodola SD  Cardenas-Hagan E  Francis DJ 《Journal of learning disabilities》2006,39(1):56-73

The effectiveness of an explicit, systematic reading intervention for first-grade students whose home language was Spanish and who were at risk for reading difficulties was examined. Participants were 69 students in 20 classrooms in 7 schools from 3 districts who initially did not pass the screening in Spanish and were randomly assigned within schools to a treatment or comparison group; after 7 months, 64 students remained in the study. The intervention matched the language of instruction of their core reading program (Spanish). Treatment groups of 3 to 5 students met daily for 50 min and were provided systematic and explicit instruction in oral language and reading by trained bilingual intervention teachers. Comparison students received the school's standard intervention for struggling readers. Observations during core reading instruction provided information about the reading instruction and language use of the teachers. There were no differences between the treatment and comparison groups in either Spanish or English on any measures at pretest, but there were significant posttest differences in favor of the treatment group for the following outcomes in Spanish: Letter-Sound Identification (d = 0.72), Phonological Awareness composite (d = 0.73), Woodcock Language Proficiency Battery-Revised Oral Language composite (d = 0.35), Word Attack (d = 0.85), Passage Comprehension (d = 0.55), and two measures of reading fluency (d = 0.58-0.75).  相似文献   

Teacher views on the effects of the change from coursework to controlled assessment in GCSEs     

Victoria Crisp  Sylvia Green 《Educational Research and Evaluation》2013,19(8):680-699

When General Certificates of Secondary Education (GCSEs) were introduced in the late 1980s, coursework was included as a requirement in many subjects. Coursework was intended to help best represent students' attainments, but concerns about various issues (e.g., tasks becoming formulaic, authenticity of student work, workload) led to a review and ultimately to its replacement with “controlled assessments”. This research investigated the effects of this change. A questionnaire was completed by 346 teachers across 6 subjects. Most teachers felt the risks of plagiarism are similar or have reduced. Two thirds of teachers reported that the introduction of controlled assessment has affected the way they teach, and around 60% feel it has affected the nature of the knowledge and skills learnt by students. There are reportedly practical challenges relating to timetabling, student absence, and increased administration. However, over 70% of teachers consider it “important” or “very important” to have some form of internal assessment in their subject.  相似文献   

Acquisition of Complex Systemic Thinking: Mental Models of Evolution     

Sylvia T. d'Apollonia  Elizabeth S. Charles  Gary M. Boyd 《Educational Research and Evaluation》2013,19(4-6):499-521

We investigated the impact of introducing college students to complex adaptive systems on their subsequent mental models of evolution compared to those of students taught in the same manner but with no reference to complex systems. The students' mental models (derived from similarity ratings of 12 evolutionary terms using the pathfinder algorithm) were significantly similar to their teachers' mental models and were correlated to their performance on an essay on evolution. Introducing students to complex systems facilitated their understanding of the mechanism of inheritance, the mechanism of evolution, and the role of chance in evolution.  相似文献   

Exploring the Lived Experiences and Intersectionalities of Mexican Community College Transfer Students: Qualitative Insights Toward Expanding a Transfer Receptive Culture     

Erin L. Castro  Edén Cortez 《Community College Journal of Research & Practice》2013,37(2):77-92

ABSTRACT

This qualitative study examines the experiences of six Mexican community college transfer students attending a research-intensive institution in the Pacific Northwest. Using semi-structured interviews, the objectives of this study were to 1) understand how Mexican students made meaning of their transfer experiences and 2) how those experiences could inform conceptual and practical thinking toward building a transfer receptive culture at the receiving institution. We use intersectionality as a site of material and discursive possibility to encourage predominantly White receiving institutions to recognize how they position Mexican community college transfer students on campus. Concluding are conceptual and practical recommendations that emphasize institutional and organizational responsibility in creating equitable environments for Mexican community college transfer students.  相似文献   

Developing Instructional Consultants: From Novice to Competent to Expert     

Sylvia Rosenfield 《Journal of educational and psychological consultation》2013,23(1-2):97-111

The development of instructional consultants requires both an understanding of the essential elements of instructional consultation (IC) and a conceptual model for development of skills. IC is a collaborative stage-based process that focuses on academic and behavioral concerns from an ecological perspective. It also emphasizes the importance of language and working relationships in the consultation process. In the first level of development, novice consultants develop awareness and conceptual understanding, as well as limited skills. Competency is achieved through application of skills in school settings with supervision that focuses, with the assistance of audiotaping the consultation sessions, on language and relationship issues as well as content. Advanced skills and proficiency emerge during extended opportunity for practice, supervision and research among those individuals who become interested in developing expertise in this domain of practice. Most training programs provide limited opportunities for competency and expertise to be developed past the novice level. It is essential to enhance educational opportunities and options if consultation practice is to achieve its full potential.  相似文献   

The Process of Fostering Consultee Development During Instructional Consultation     

Steven E. Knotek  Sylvia A. Rosenfield  Todd A. Gravois  Leslie M. Babinski 《Journal of educational and psychological consultation》2013,23(3-4):303-328

This investigation examines how the process of instructional consultation (IC) supports consultees' problem-solving and fosters change in how the consultees understand pertinent work problems. The setting was a mid-Atlantic elementary school's Instructional Consultation Team, and the participants were 13 case manager consultants and 5 teacher consultees. A micro-ethnographic research approach was used and 4 primary sources of data collected: interviews, direct observations, consultation documents, and IC training documents. Analysis of the data uncovered 4 general themes related to the participants' problem-solving and evolving understanding of the work issues. In the discussion, the question of how IC is a constructive process that promotes consultees' development is considered.  相似文献   

“I never thought this could be for me”: aspirational capital,identities, and political engagement among first-generation college students in São Paulo     

Charles H. Klein  Milena Mateuzi Carmo 《International Studies in Sociology of Education》2019,28(3-4):259-278

ABSTRACT

Today, young adults from lower-income backgrounds are pursuing educational trajectories that would have been distant dreams for their parents. In many Global South countries, this expansion has followed a neoliberal logic in which private universities purport to provide students skills and increased earning capacity, and employers the necessary human capital to compete in global markets. This article examines these processes in Brazil, where federal policies have contributed to a dramatic growth in private, for-profit higher education in recent years. Building on ethnographic research in São Paulo’s expansive peripheries, our analysis examines three inter-related themes: higher education and life aspirations; intersectional identity construction; and political/community engagements. We argue that while neoliberal ideologies and policies are a key component of Brazilian higher education, many first-generation college students actively – and critically – challenge everyday oppressions and create new life possibilities in the context of enduring inequalities.  相似文献
