Evolution and validation of a personal form of an instrument for assessing science laboratory classroom environments     

Barry J. Fraser  Geoffrey J. Giddings  Campbell J. McRobbie 《科学教学研究杂志》1995,32(4):399-422

The research reported in this article makes two distinctive contributions to the field of classroom environment research. First, because existing instruments are unsuitable for science laboratory classes, the Science Laboratory Environment Inventory (SLEI) was developed and validated. Second, a new Personal form of the SLEI (involving a student's perceptions of his or her own role within the class) was developed and validated in conjunction with the conventional Class form (involving a student's perceptions of the class as a whole), and its usefulness was investigated. The instrument was cross-nationally fieldtested with 5,447 students in 269 senior high school and university classes in six countries, and cross-validated with 1,594 senior high school students in 92 classes in Australia. Each SLEI scale exhibited satisfactory internal consistency reliability, discriminant validity, and factorial validity, and differentiated between the perceptions of students in different classes. A variety of applications with the new instrument furnished evidence about its usefulness and revealed that science laboratory classes are dominated by closed-ended activities; mean scores obtained on the Class form were consistently somewhat more favorable than on the corresponding Personal form; females generally held more favorable perceptions than males, but these differences were somewhat larger for the Personal form than the Class form; associations existed between attitudinal outcomes and laboratory environment dimensions; and the Class and Personal forms of the SLEI each accounted for unique variance in student outcomes which was independent of that accounted for by the other form.  相似文献   

Feed-forward: students gaining more from assessment via deeper engagement in video-recorded presentations     

Karen Murphy  Shane Barry 《Assessment & Evaluation in Higher Education》2016,41(2):213-227

Presentation feedback can be limited in its feed-forward value, as students do not have their actual presentation available for review whilst reflecting upon the feedback. This study reports on students’ perceptions of the learning and feed-forward value of an oral presentation assessment. Students self-marked their performance immediately after their presentation, after reviewing a video recording of their presentation and wrote a reflection relating to their experience. Survey data revealed that most students viewed all aspects of the assessment task positively and they rated the process as providing substantial learning value. They also indicated that the video review and overall assessment exercise provided valuable feed-forward information that would assist them to improve future presentations. These data were further supported by content analysis of the qualitative data. Students noted that they perceived the video review task as self-enabling. They also noted that the self-reflection and self-marking exercise provided time for thought although it was personally challenging. Therefore, via carefully designed assessment, it is possible to provide a deep learning opportunity from oral presentations that can feed-forward to enhance students’ future presentations.  相似文献

Editor's Note: The following is a continuation of the dialogue “A Correspondence of Academic Interest” in the Spring 1994 issue ofAcademic Questions. That exchange concerned the program, recently announced by the Teachers Insurance and Annuity Association-College Retirement Equities Fund (TIAA-CREF), to promote diversity on the governing boards of the public corporations in which it invests.  相似文献   

A content analysis of research published in the Journal of Research in Science Teaching from 1985 through 1989     

Phillip B. Horton  Andrew A. McConney  Amanda L. Woods  Kevin Barry  Homer L. Krout  Barbara K. Doyle 《科学教学研究杂志》1993,30(8):857-869

To determine if actual practice was consistent with commonly recommended research methods and procedures, this study examined 130 studies reported over a 5-year period in three volumes of the Journal of Research in Science Teaching (JRST). The results were consistent with similar previous analyses (Shaver & Norton, 1980a, 1980b; Wallen & Fraenkel, 1988a) and indicate that appropriate generalizations beyond the confines of the reported studies may be impossible for most (64%) of the JRST studies surveyed. The findings also show that replication studies, which could be employed to offset deficiencies in generalizability, were not commonly encountered (3%) in these 130 reports. In addition, the study results indicate that many researchers (48%) do not properly restrict their conclusions based on the limits imposed by the accessible populations and samples used; nor do they typically provide possible alternative explanations for the outcomes obtained (76%). These findings prompt the following recommendations: 1. A greater awareness and use of replication as a check on generalizability should be encouraged by the science education community. 2. Clearly defined populations (target and accessible) and fully described samples warrant increased attention as report components from authors, reviewers, and editorial board members of JRST. 3. In light of the difficulties inherent in effecting random selection in educational settings, a greater emphasis should be placed on recognizing the limits that the underlying assumptions of inferential statistics place on research conclusions. The results of this study indicate that the methodological quality of published science education research should remain a concern for both practitioners and readers.  相似文献

Enriching Professional Learning Networks: A Framework for Identification,Reflection, and Intention     

Daniel G. Krutka  Jeffrey Paul Carpenter  Torrey Trust 《TechTrends》2017,61(3):246-252

Many educators in the 21st century utilize social media platforms to enrich professional learning networks (PLNs). PLNs are uniquely personalized networks that can support participatory and continuous learning. Social media services can mediate professional engagements with a wide variety of people, spaces and tools that might not otherwise be available. Teachers who once might have had access to only a handful of colleagues can now employ Facebook, Twitter and other mediums to learn from peers across the globe at any time. However, educators face numerous challenges building and enhancing their PLNs for professional growth. To support educators in the development of their PLNs, we present a framework for PLN enrichment. Rooted in our research and experiences with PLNs, this flexible framework is designed to help educators reflect upon how they might continuously improve their PLN experiences and outcomes.  相似文献   

Maintenance of keypecking in pigeons by a food avoidance but not by a shock avoidance contingency     

Barry Schwartz 《Learning & behavior》1973,1(3):164-166

Response key illuminations were followed by food delivery or shock, and keypecks were programmed to prevent the occurrence of whichever stimulus was scheduled. At high shock intensity, pigeons did not peck: at low shock intensity, pigeons pecked in about half of the trials. When different key colors signaled food and shock trials, pigeons pecked on food trials, thus preventing food delivery, but not on shock trials, thus failing to avoid shock delivery. That pecks occurred despite the fact that they avoided food but did not occur when they avoided shock is taken as evidence that the keypeck is frequently governed by biological predispositions, and not by its consequences.  相似文献   

Assessing the psychosocial environment of science classes in Catholic secondary schools     

Mr Jeffrey P. Dorman  Dr Campbell J. McRobbie  Dr Barry J. Fraser 《Research in Science Education》1993,23(1):61-67

Much Catholic school and church rhetoric suggests that Catholic schools possess distinctive learning environments. Research into this aspect of Catholic schooling has been hampered by the lack of an appropriate assessment instrument. By drawing on contemporary church literature, the perceptions of personnel involved in Catholic education and existing classroom environment questionnaires, a new instrument was developed to assess student perceptions of classroom psychosocial environment in Catholic schools. The use of this instrument in 64 classrooms in Catholic and Government schools indicated significant differences on some scales. The distinctive nature of Catholic schooling did not extend to all classroom environment dimensions deemed important to Catholic education. Specializations: Catholic education, learning environments. Specializations: conceptual change in students, science teacher professional development, scientific reasoning, learning environments. Specializations: learning environments, science education, educational evaluation, curriculum.  相似文献   

Research on Teacher Effectiveness: Implications for Remedial Teachers     

Barry A. Fields 《International Journal of Disability, Development & Education》1987,34(2):117-132

Over the past decade considerable progress has been made in defining and describing teacher behaviours associated with high levels of pupil achievement. Collectively described as teacher effectiveness research, this body of knowledge is now influencing conceptions of effective teaching in special education settings. What is unclear, however, is the extent to which special education teachers are aware of this research, perceive it to be important, and actually use the findings in their day‐to‐day teaching. Nor is it clear what, if any, modifications are needed when findings are applied to instruction with low achieving and mildly handicapped children. The present study addresses the questions of the perceived importance of and the need for adaptations to teacher effectiveness findings as they relate to a sample of Queensland remedial teachers.  相似文献
