Abstract: Food science laboratory courses are traditionally taught as a series of preplanned laboratories with known endpoints. In contrast, inquiry‐guided (IG) laboratories allow students to ask questions, think through problems, design experiments, then adapt and learn in response to unexpected results. This study examined the effects of converting the course, “Analytical Techniques in Food and Bioprocessing Sciences” from a traditional approach (2008 to 2010 data) to an IG approach (2011 data) by assigning teams of 2–3 students a food and a set of 5 analyses to conduct over the course of the semester. Students were required to choose and justify the use of specific methods for each analysis, as well as to develop a supply list and a budget for the semester‐long project. During the semester, students were required to post and discuss their weekly progress with the instructor, teaching assistants, and the rest of the class using an online discussion forum. At the end of the semester, students were required to present the results of their analysis in both oral and written formats. Overall course grades were significantly higher (P≤ 0.05) using IG in 2011 compared to 2010 and 2009, but not to 2008 grades. Numerical course evaluations for the instructor, overall course, and lab, as well as written course evaluations all significantly (P≤ 0.05) improved. This suggests that an IG approach may measurably improve student performance in terms of course grades and the ability to complete semester long projects. It may also increase student satisfaction with the course, as measured by numerical and written end of semester surveys.  相似文献   

Children's Norm Enforcement in Their Interactions With Peers     

Bahar Köymen  Elena Lieven  Denis A. Engemann  Hannes Rakoczy  Felix Warneken  Michael Tomasello 《Child development》2014,85(3):1108-1122

This study investigates how children negotiate social norms with peers. In Study 1, 48 pairs of 3‐ and 5‐year‐olds (N = 96) and in Study 2, 48 pairs of 5‐ and 7‐year‐olds (N = 96) were presented with sorting tasks with conflicting instructions (one child by color, the other by shape) or identical instructions. Three‐year‐olds differed from older children: They were less selective for the contexts in which they enforced norms, and they (as well as the older children to a lesser extent) used grammatical constructions objectifying the norms (“It works like this” rather than “You must do it like this”). These results suggested that children's understanding of social norms becomes more flexible during the preschool years.  相似文献   

A synergistic approach to turning the tide of grade inflation     

Kim C. O’Halloran  Michael E. Gordon 《Higher Education》2014,68(6):1005-1023

Higher education in the United States is facing increasing demands for colleges and universities to demonstrate what students learn and that they are providing a high-quality education experience during the undergraduate years (Pascarealla et al. in Chang Mag High Learn 42(1):16–22, 2010). Despite evidence of the elevation of grades in higher education dating back to the 1970s, attempts to rein in this phenomenon have been largely unsuccessful (Nikolakakos et al. in Coll Univ 87(3):2–14 2012). It is our contention that attempts to reform grading have not succeeded because their focus is too narrow. After providing background information on the extent and causes of grade inflation, we will propose a synergistic approach to dealing with the problem of grade inflation.  相似文献   

The Dialectical Relationship Between Place and Space in Education: How the Internet Is Changing Our Perceptions of Teaching and Learning     

Michael Glassman  Jonathan Burbidge 《Educational theory》2014,64(1):15-32

In this essay Michael Glassman and Jonathan Burbidge explore the idea of a dialectical relationship between the traditional place(s) of teaching/learning settings and the challenges to our perceptions created by the new spaces of the Internet. The authors examine this topic in the context of a three‐stage evolution of humans' relationship with new technologies: (1) fear of how new technologies will change our everyday actions, (2) recognition of emerging technologies as tools capable of offering new possibilities in our activities, and (3) integration of new technologies into productive everyday activities. The Internet is moving quickly through all three stages, but this process takes different forms with disparate populations. What makes recognition of the fast‐moving integration of Internet technology important in the field of education is that students and educators are often at different points in this process. It is critical that we are aware of the role technology is playing in the classroom, in particular the dynamic dialectical relationship between space and place.  相似文献   

‘I Knew Jean-Paul Sartre’: Philosophy of education as comedy     

Morwenna Griffiths  Michael A. Peters 《Educational Philosophy and Theory》2014,46(2):132-147

Abstract

Ludwig Wittgenstein suggests that ‘A serious and good philosophical work could be written consisting entirely of jokes’. The idea for this dialogue comes from a conversation that Michael Peters and Morwenna Griffiths had at the Philosophy of Education of Great Britain annual meeting at the University of Oxford, 2011. It was sparked by an account of an assessment of a piece of work where one of the external examiners unexpectedly exclaimed ‘I knew Jean-Paul Sartre’, trying to trump the discussion. This conversation is a dialogue about comedy and humor as a basis for philosophy, education and pedagogy that provides an introduction to recent works and a context for ongoing research. The concluding section provides further reflection on some of the main themes, drawing attention to the significance of humor in dialogues within philosophy and education, and suggesting that it has a particular role in resisting managerialism at all levels of educational institutions.  相似文献   

PERSONNEL NEEDS IN SCHOOL PSYCHOLOGY: A 10‐YEAR FOLLOW‐UP STUDY ON PREDICTED PERSONNEL SHORTAGES     

Jose M. Castillo  Michael J. Curtis  Sim Yin Tan 《Psychology in the schools》2014,51(8):832-849

Concerns regarding whether a sufficient supply of school psychologists exists have been evident for decades. Studies have predicted that school psychology would face a critical personnel shortage that would peak in 2010, but continue into the foreseeable future. The current study is a 10‐year follow‐up investigation based on previously published personnel shortage projections. Data derived from the National Association of School Psychologists 2009–2010 national study were used to examine current personnel shortages as well as to project the extent to which personnel shortages are likely to continue. Findings indicate that the field of school psychology continues to experience a personnel shortage that will continue through 2025. Additionally, greater rates of retirements are projected for the field for school psychologists who are males, who possess a doctoral degree, and for university faculty. Analyses based on the U.S. Census Regions indicate that notable differences are likely to occur in the match between the supply of and demand for school psychologists based on geographical location. Implications are discussed relating to the recruitment and retention of school psychologists and to the services they deliver.  相似文献   

Afterword. Anarchism,texts and children: active conversations with the past     

Michael Fielding 《Paedagogica Historica: International Journal of the History of Education》2014,50(4):460-464

In appreciating and responding to the three symposium papers on “Anarchism, Texts and Children”, a case is made for what John Berger has called “the honour of an alternative”, for affirmation as well as for refusal. Not only should we respond positively and imaginatively to Colin Ward’s call for “counter-history” of our own making, we should also extend our advocacy of alternatives through the adventure of more creative historical methodologies. Lastly, in the spirit of Berger’s writing, this Afterword celebrates the capacity of all three papers not just to speak to issues of enduring human importance, but to do so imaginatively and eloquently, thereby refusing and subverting the increasingly dreary hegemony of academic writing disgracefully in thrall to the diminishing calculus of neo-liberalism.  相似文献   

Examining the developmental trajectories of adolescent sexual offenders     

Lesleigh E. Pullman  Elisabeth J. Leroux  Gregory Motayne  Michael C. Seto 《Child abuse & neglect》2014

The aim of the current study was to assess the validity of the sex-plus versus sex-only categorization method for distinguishing between different types of adolescent sex offenders (ASOs; Butler & Seto, 2002). It is hypothesized that this categorization method has utility when attempting to distinguish between generalist and specialist ASOs (Seto & Pullman, 2014). Additionally, further classification of ASOs was attempted using a well known juvenile delinquency classification scheme, early-onset versus late-onset offenders (Moffitt, 1993). The current study was an archival analysis of clinical files from a sample of 158 male ASOs seen for clinical assessment at a Metropolitan Family Court Clinic. Results indicate that sex-plus offenders are more antisocial, exhibit more psychiatric issues, and have greater deficits in general social skills compared to sex-only offenders. Conversely, sex-only offenders were found to have more atypical sexual interests, and were more likely to have greater deficits in romantic relationships compared to sex-plus offenders. Due to a power related limitation, little support was found for the use of the early-onset versus late-onset classification scheme with ASOs. Overall, these results provide further support to the validity of a sex-only versus sex-plus distinction. Given these results mirror those found in the generalist/specialist literature regarding the etiology of ASOs, sex-only and sex-plus offenders may indeed have different etiological pathways: sex-plus offenders are more driven by general antisociality factors, as the generalist perspective suggests, and sex-only offenders are more driven by special factors, as the specialist explanations suggest.  相似文献   

THE EFFECTS OF MIDDLE SCHOOL BULLYING AND VICTIMIZATION ON ADJUSTMENT THROUGH HIGH SCHOOL: GROWTH MODELING OF ACHIEVEMENT,SCHOOL ATTENDANCE,AND DISCIPLINARY TRAJECTORIES     

Marissa A. Feldman  Tiina Ojanen  Ellis L. Gesten  Heather Smith‐Schrandt  Michael Brannick  Christine M. Wienke Totura  Lizette Alexander  David Scanga  Ken Brown 《Psychology in the schools》2014,51(10):1046-1062

The current 5‐year longitudinal study examined the effects of middle school bullying and victimization on adolescent academic achievement, disciplinary referrals, and school attendance through high school (N = 2030; 1016 both boys and girls). Greater engagement in bullying behaviors was concurrently associated with lower achievement and school attendance for girls and higher levels of disciplinary problems, and, for girls, predicted increases in disciplinary referrals through high school. Victimization was unrelated to school adjustment difficulties when controlling for bullying. Moreover, academic achievement was longitudinally associated with disciplinary referrals and school attendance. These findings outline concurrent school adjustment difficulties associated with engagement in bullying behavior, the longer‐term behavioral ramifications for girls, and the relations of behavioral and academic development from middle school to high school.  相似文献   

Behavioral and emotional strength-based assessment of Finnish elementary students: psychometrics of the BERS-2     

Erkko Tapio Sointu  Hannu Savolainen  Matthew C. Lambert  Kristiina Lappalainen  Michael H. Epstein 《European Journal of Psychology of Education - EJPE》2014,29(1):1-19

When rating scales are used in different countries, thorough investigation of the psychometric properties is needed. We examined the internal structure of the Finnish translated Behavioral and Emotional Rating Scale-2 (BERS-2) using Rasch and confirmatory factor analysis approaches with a sample of youth, parents, and teachers. The results suggested that the Finnish translated BERS-2 has acceptable measurement properties and is suitable for use in Finnish schools. Results highlighted the issue that there is a need to consider cross-cultural aspects when introducing new measures in another culture. Directions for future research are also discussed in light of present findings.  相似文献
