Adding an extra dimension to what students see through the light microscope: a lab exercise demonstrating critical analysis for microscopy students     

Garrill A 《CBE life sciences education》2011,10(4):430-435

This article describes an undergraduate lab exercise that demonstrates the importance of students thinking critically about what they see through a microscope. The students are given growth data from tip-growing organisms that suggest the cells grow in a pulsatile manner. The students then critique this data in several exercises that incorporate aspects of a problem-based learning approach, envisaging growth not just in two dimensions, but in three dimensions. For some cells, what appears to be pulsatile growth could also be explained by growth at a constant rate up and down in the z-axis. Depending on the diffraction pattern generated by the tip of the cell, this movement in the z-axis could go undetected. This raises the possibility that pulsatile growth seen in some species may be an artifact generated by the limitations of the light microscope. Students were subsequently asked to rate their awareness of the need to think critically about what they see through a microscope, using a scale of 1 (unaware) to 5 (very much aware). Prior to doing the lab exercise, the mean rating was 2.7; this increased to 4.4 after the lab. The students also indicated a likelihood of being more critical in their thinking in other aspects of their biology curriculum.  相似文献

GENDER DIFFERENCES IN WRITTEN EXPRESSION CURRICULUM‐BASED MEASUREMENT IN THIRD‐ THROUGH EIGHTH‐GRADE STUDENTS     

Jamie Y. Fearrington  Patricia D. Parker  Pamela Kidder‐Ashley  Sandra G. Gagnon  Sara McCane‐Bowling  Christy A. Sorrell 《Psychology in the schools》2014,51(1):85-96

Many studies have found gender differences in certain areas of academic achievement, such as reading and math. Fewer studies have examined gender disparities in writing skills. The current study explored gender differences in written expression performance. Participants were 1,240 male and female students in third through eighth grade, representing five schools in a rural southeastern school district. Each student was administered an AIMSweb curriculum‐based measurement writing probe during the district's regularly scheduled fall, winter, and spring benchmarks. All measures were scored for total words written and correct writing sequences. Two‐way repeated measures analyses of variance were used to determine whether differences existed in the sample. A significant female advantage was found on both scoring indices at each grade level. These findings have strong instructional and theoretical implications for practicing school psychologists and other educators.  相似文献   

ETHICAL CONSIDERATIONS IN A THREE‐TIERED APPROACH TO SCHOOL DISCIPLINE POLICY AND PRACTICE     

Ashley M. Mayworm  Jill D. Sharkey 《Psychology in the schools》2014,51(7):693-704

Research indicates that school discipline policies and practices have a significant influence on both student and school functioning. The purpose of this article is to uncover how the ethical standards guiding the field of school psychology inform school decisions about discipline in a three‐tiered approach. Various discipline approaches, empirical research evaluating the effectiveness of these approaches, and the role of school psychologists in school discipline decision making are reviewed. Ultimately, this integration of theory, empirical research, and ethical standards points to the importance of creating comprehensive and individualized school discipline policies that apply ethically sound practices at all three tiers of intervention. Implications for practicing school psychologists are discussed.  相似文献   

Cultural Misperceptions and Goals for Samoan Children’s Education in Hawai’i: Voices from School, Home, and Community     

Marianna Fischer Valdez  Peter W. Dowrick  Ashley E. Maynard 《The Urban Review》2007,39(1):67-92

Research lauds the benefits of parent involvement in the schools, yet many schools and communities have not achieved desired levels of involvement. Underlying expectations and methods soliciting parent involvement may be rooted in cultural misperceptions. This study, based on Epstein’s (1987) Overlapping Spheres of Influence model, explored the ways and extent that community members, school staff, and Samoan families interact regarding a public middle school. Qualitative research methods (interviews and observations) involved parents, teachers, administrators, and community agency members and officials in participatory action research. Findings displayed a base of cultural differences regarding parent involvement: Samoan parents were expected to participate in school events and assist children with homework, yet Samoan culture has historically divided the parents’ responsibilities from the teachers’ responsibilities. Parents identified their responsibilities for children’s spirituality and discipline and viewed academic matters as solely the responsibility of teachers. The school’s new activities, parents’ shifting focus, and community members’ diverse actions are demonstrating a start of change. This research supports the need for school personnel to understand the cultural roots of minority families’ parent involvement practices. Marianna F. Valdez is a Ph.D. Candidate in Community and Cultural Psychology. She completed her M.A. degree at the University of Hawaii and B.A. degree at Tulane University. Her research interests involve the development, implementation, and evaluation of culturally appropriate community programs, especially related to the public school setting. She is most interested in understanding and representing emic perspectives to drive action research, informed by culturalist approaches and mixed methods. Peter W. Dowrick is Professor of Disability Studies and affiliate graduate faculty in Psychology at the University of Hawaii. He completed his Ph.D. at the University of Auckland, ATCL at Trinity College London, M.Sc. at the University of Auckland, and B.Sc. at the Victoria University of Wellington. He has wide experience working with people marginalized by culture, disability, mental health, and other considerations. His consultation on prevention and intervention extends to 31 states and 21 countries. His overarching contribution has been in the concepts of feedforward and creating futures, applied in situations of personal safety, serious mental illness, social behavior, sports and recreation, daily living, literacy, academic skills, health, housing, management, and jobs, among others. Ashley E. Maynard is Associate Professor in the Department of Psychology at the University of Hawaii. She completed her Ph.D. at the University of California, Los Angeles, M.A. at the University of California, Los Angeles, and B.A. at the University of Virginia. She studies the interrelationships of culture, contexts of child development, and healthy cognitive and social development of children. Based on a socio-cultural paradigm, the theoretical question that lies at the heart of her research program is the ways in which a variety of culturally based activity settings influence adaptive pathways of development for children and families.

Revealing conceptual understanding of international business     

Sue Ashley  Harmen Schaap  Elly de Bruijn 《Assessment & Evaluation in Higher Education》2017,42(5):690-704

This study aims to identify an adequate approach for revealing conceptual understanding in higher professional education. Revealing students’ conceptual understanding is an important step towards developing effective curricula, assessment and aligned teaching strategies to enhance conceptual understanding in higher education. Essays and concept maps were used to determine how students’ conceptual understanding of international business can be revealed adequately. To this end, 132 international business students in higher professional education were randomly assigned to four conditions to write essays and to construct concept maps about an international business research topic. The conditions were: essay alone, essay after concept map, concept map alone, and concept map after essay. An assessment rubric was used to assess the breadth and depth of students’ conceptual understanding. Results show essays are the most adequate approach for revealing conceptual understanding of international business. In particular, concept maps revealed fewer facts and less reasoning than essays. Essays written after concept maps were less effective than essays, possibly since students perceived these essays as redundant. Further research is suggested on how educators can foster conceptual understanding.  相似文献

The Black Women’s Gathering Place: reconceptualising a curriculum of place/space     

Arianna Howard  Ashley Patterson  Valerie Kinloch  Tanja Burkhard  Ryann Randall 《Gender and education》2016,28(6):756-768

ABSTRACT

This article de-centres imperialist, capitalist, patriarchal traditions of critical approaches in Curriculum Studies via an examination of experiences shared at The Black Women’s Gathering Place (BWGP), a non-traditional space where a diverse, intergenerational group of Black women engage with each other through the sharing of stories. In the BWGP, we enact components of Pinar’s [2004. What is Curriculum Theory? Mahwah, NJ: Lawrence Erlbaum] concept of currere, simultaneously re-entering our collective and individual pasts and re-imagining our futures in an effort to reconcile our public and private selves. Taking up tenets of Black feminist theory, theoretical framings of hidden curriculum, and components of Ng-A-Fook’s [2007. An Indigenous Curriculum of Place: The United Houma Nation’s Contentious Relationship with Louisiana’s Educational Institutions. New York, NY: Peter Lang] ‘Curriculum of Place,’ we reconceptualise a curriculum of place/space that negotiates dominant norms expressed in social environments. In this space, we validate traditional knowledges upheld in communities of Black women across the Diaspora. The BWGP allows us to argue for a re-presentation of extant knowledge by and about Black women.  相似文献   

Instrument Development and Validation of the Infant and Toddler Assessment for Quality Improvement     

Michal Perlman  Ashley Brunsek  Anne Hepditch  Karen Gray  Olesya Falenchuck 《Early education and development》2017,28(1):115-133

Research Findings: There is a growing need for accurate and efficient measures of classroom quality in early childhood education and care (ECEC) settings. Observational measures are costly, as their administration generally takes 3–5 hr per classroom. This article outlines the process of development and preliminary concurrent validity testing of the Assessment for Quality Improvement (AQI), a new measure of global quality. The AQI is a classroom-level measure of structural and process quality. It consists of 24 items on a 5-point scale designed for use in ECEC infant and toddler classrooms. At between 60 and 90 min per room, the AQI is a relatively efficient measure. Item response theory modeling was used to ensure logical and coherent ordering of subitems. Exploratory factor analysis supported the use of the AQI total score and the Interactions section as a stand-alone measure. Correlations between the Infant and Toddler versions of the AQI and the Infant/Toddler Environment Rating Scale–Revised were moderate, providing preliminary support for the concurrent validity of both versions. Practice or Policy: Our results suggest that the AQI is a promising, efficient measure of global quality in infant and toddler ECEC environments. This may be especially relevant for Quality Rating and Improvement Systems, for which the observational component is a major cost driver.  相似文献   

Academic growth trajectories of ELLs in NAEP data: The case of fourth- and eighth-grade ELLs and non-ELLs on mathematics and reading tests     

Nihat Polat  Ashley Zarecky-Hodge  James B. Schreiber 《The Journal of educational research》2016,109(5):541-553

Utilizing the National Assessment of Educational Progress (NAEP) data, this study examined (1) how fourth and eighth-grade ELLs' mathematics and reading scores on national tests compared to their non-ELL peers' scores over the testing period between 2003 and 2011, and (2) if gender and ethnicity contributed to variation in the growth patterns among the student groups across grade levels and content areas. Since the NAEP data, which provides a national sample of 10,000–20,000 students, is collected using a probability sample design, sampling weights are adjusted so inferences can be appropriately made. Sample sizes within NAEP are large enough to generate adequate power for statistical significance. Thus, to display the data in a multivariate mode, Tableau 8.0.0 software was used. Results suggested that the achievement gap between non-ELLs and ELLs is either steady or slightly widening in both mathematics and reading, with multiple paths across the content areas, grade levels, and gender and ethnic groups.  相似文献
