Research suggests that undergraduate students learn more from lab experiences that involve longer-term projects. We have developed a one-semester laboratory sequence aimed at sophomore-level undergraduates. In designing this curriculum, we focused on several educational objectives: 1) giving students a feel for the scientific research process, 2) introducing them to commonly used lab techniques, and 3) building skills in both data analysis and scientific writing. Over the course of the semester, students carry out two project-based lab experiences and write two substantial lab reports modeled on primary literature. Student assessment data indicate that this lab curriculum achieved these objectives. This article describes the first of these projects, which uses the biflagellate alga Chlamydomonas reinhardtii to introduce students to the study of flagellar motility, protein synthesis, microtubule polymerization, organelle assembly, and protein isolation and characterization.  相似文献   

Thinking through practice: exploring ways of knowing,understanding and representing the complexity of teaching     

Donna Mathewson Mitchell 《Asia-Pacific Journal of Teacher Education》2013,41(4):414-425

In recent times there has been a cross-disciplinary amplification of interest in the concept of practice. In this context, there is a growing body of research considering how teaching and teacher education might be viewed using the conceptual lens of practice. In this article, I explore practice theories to identify common themes and principles that constitute a conceptual framework for the investigation of the lived experience of teaching. From this foundation, a methodological framework based on collaborative inquiry and postmodern emergence is derived. Examples are offered of the way the conceptual framework and methodological approach have been activated through the first stage of a research programme that collaboratively engages the dual voices of academic researcher and classroom practitioners as co-researchers. Analysis of qualitative data reveals the potential and limitations of this practice-based foundation as a way to know, understand and represent the complexity of teaching. In conclusion, the article develops a number of propositions as the basis for further research.  相似文献   

Student teachers' concerns and accomplishments on main school placements: what school mentors can learn from them     

Paul Stephens 《Mentoring & Tutoring: Partnership in Learning》2013,21(1):56-66

The article highlights the concerns and accomplishments of secondary school student teachers during their main attachment to schools. It also reports on the things school mentors do that student teachers find helpful and unhelpful. While the author does not make any ‘grand’ claims, he does offer a number of grounded good practice pointers that school mentors might want to engage.  相似文献   

Visualizing the politics of innocence in the age of AIDS     

Claudia Mitchell  Shannon Walsh  June Larkin 《Sex education》2013,13(1):35-47

We are concerned with the ways in which social constructions of age can contribute to reducing or exacerbating the vulnerability of young people, and for this reason we refer to the issue as one of ‘the politics of innocence’. The focus of this paper is on gender, youth and HIV prevention/AIDS awareness in the context of South Africa and investigates the uses (and abuses) of images of ‘childhood’, ‘youth’ and ‘adolescence’ in the age of AIDS. Notwithstanding the particular case of South Africa where the incidence of new cases of HIV infection amongst young people is at crisis proportions, the impetus for our work on the visual representations of youth, gender and AIDS comes out of a recognition of the increasing risk of youth to sexually transmitted infections, HIV and AIDS, and within that the particular vulnerability, worldwide, of young women.  相似文献   

Profiles in Change: An Alternative Look at the Marshall Hypotheses∗     

John K. Cochran  Beth Sanders  Mitchell B. Chamlin 《Journal of Criminal Justice Education》2013,24(2):205-226

U.S. Supreme Court Justice Thurgood Marshall once argued that informed opinion would oppose the death penalty for all but those who support it for retributive reasons. We examine the validity of these claims with data from a series of one‐group pre‐test–post‐test designs which stem from a formalized learning outcomes assessment for several courses on the death penalty. Results show solid, but imperfect, support for these claims. The analysis then proceeds by profiling those who changed their opinions consistent with these claims, those who did not change their opinions, and those whose opinions changed in a manner opposite to these claims.  相似文献   

Adult Learner Graduation Rates at Four U.S. Community Colleges by Prior Learning Assessment Status and Method     

Milan S. Hayward  Mitchell R. Williams 《Community College Journal of Research & Practice》2013,37(1):44-54

The completion agenda demands higher community college graduation rates among adult learners, and prior learning assessment (PLA) is a promising solution. PLA permits students to earn credit for college-level learning acquired outside of higher education and is associated with improved student outcomes. However, little is known regarding community college graduation rates among adult learners by prior learning assessment status and method. Therefore, the purpose of the current study was to examine adult learner graduation rates by PLA status and method at four U.S. community colleges. Results from this foundational study confirmed a remarkable difference in graduation rates between adult PLA learners and adult non-PLA learners, uncovered striking differences in the graduation rates of adult PLA learners by PLA method, and identified a relationship between PLA method and graduation. Findings provide community college stakeholders with new insight into adult PLA learners in the community college and a basis for future research leading to higher graduation rates among adult learners.  相似文献   

THE DISSEMINATION OF A UNIVERSITY FIELD PLACEMENT PROGRAM: IMPACT ON RECRUITMENT,SATISFACTION AND EFFECTIVENESS     

Christina M. Mitchell 《Community College Journal of Research & Practice》2013,37(1-4):141-153

Community college field placements often reflect a “vocational education” approach to outside‐the‐classroom learning, attempting to train students in specific skills and prerequisites for predetermined job slots. In the human services area, however, this may not be the most advantageous approach to producing innovative workers who will generate creative solutions to persistent and serious social problems. This study examined the impact of utilizing one popular university approach to field learning‐experiential learning coupled with social change agentry—with community college students. A criterion‐group field experiment was conducted, looking at paper‐and‐pencil measures, interviews, and archival data. It was found that the community college students were as willing to participate, were equally satisfied with the experience, and were as effective with their assigned cases as were the university students in this rigorous and demanding field placement. Community college administrators who are seeking to broaden their human service field settings should also consider successful university models of experiential learning as alternatives.  相似文献

Young people with high‐functioning autism and Asperger's syndrome planning for and anticipating the move to college: what supports a positive transition?     

Wendy Mitchell  Bryony Beresford 《British Journal of Special Education》2014,41(2):151-171

For many young people in England, the move into continuing education involves a transfer from the school where they were educated to a further education college. For those with high‐functioning autism or Asperger's syndrome, this can be a challenging process. Past research has demonstrated some of the problems that these young people can encounter. This article by Wendy Mitchell and Bryony Beresford, both based in the Social Policy Research Unit at the University of York, adds to the evidence base by describing how best to support these young people, focusing specifically on ‘young person endorsed’ practice. Data are gleaned from qualitative interviews with 18 young people with high‐functioning autism/Asperger's syndrome. Findings reveal that young people welcomed the involvement of practitioners; however, specific forms of help and knowledge were particularly valued. In addition, it was parents, as opposed to professionals, who typically emerged as the most significant and valued source of support. Implications for practice are discussed, including the support needs of parents.  相似文献
