This paper explores the shared experiences of practices of blended librarianship among Zimbabwean academic librarians to identify how adequately they comply with their dynamic roles and functions. The paper relies on the theoretical constructs from Bell and Shank's (2004, 2007) blended librarianship and Lave and Wenger's (1991) Legitimate Peripheral Participation (LPP) to understand how Zimbabwean academic librarians practice blended librarianship in the workplace through engagement in legitimate work tasks. The investigators used phenomenology to explore academic librarians' experiences of blended librarianship. They selected a sample of 101 academic librarians and delivered a semi-structured questionnaire to the sample, conducted document research and interviewed key informants from the sample. The researchers collected data from the Bindura University of Science Education, Chinhoyi University of Technology, Lupane State University, Midlands State University, the National University of Science and Technology, and PHSBL80 Library which chose to be undisclosed. Each institution adopted blended librarianship in its way. Four (4) different categories of blended librarianship emerged from the experiences; that is “transcending blended librarians”, “partially blended librarians”, “intermittent blended librarians” and “aspiring blended librarians”, displaying each institution's level of instructional technology and instructional design roles. The study proposes that the “Academic librarian's transition to blended librarianship” two-by-two matrix that developed was in this inquiry needs further refinement. Further enquiries may test the matrix within the same sites or other locales altogether to corroborate if the results are replicable. 相似文献

A new item parameter replication method is proposed for assessing the statistical significance of the noncompensatory differential item functioning (NCDIF) index associated with the differential functioning of items and tests framework. In this new method, a cutoff score for each item is determined by obtaining a (1 −α) percentile rank score from a frequency distribution of NCDIF values under the no-DIF condition by generating a large number of item parameters based on the item parameter estimates and their variance-covariance structures from a computer program such as BIILOG-MG3. This cutoff for each item can be used as the basis for determining whether a given NCDIF index is significantly different from zero. This new method has definite advantages over the current method and yields cutoff values that are tailored to a particular data set and a particular item. A Monte Carlo assessment of this new method is presented and discussed. 相似文献

Purpose: The study aims at finding out relevance and knowledge levels of selected teaching competencies as perceived by educational administrators, faculty and students, in order to assess the training needs of faculty of agricultural universities.
Methodology: Relevance and knowledge levels were tested through a teaching competency questionnaire developed and run on 292 respondents fitting into administrator, faculty and student groups. Needs Assessment Model by Borich [1980. “A Needs Assessment Model for Conducting Follow-up Studies.” Journal of Teacher Education 31 (3): 39–42] is used to identify training needs.
Findings: Results indicate differences in perceptions among groups towards teaching competencies. Prioritized training needs were identified which provide the content and direction for the development of faculty in-service educational programmes.
Practical implications: Faculty of agricultural universities need periodic in-service training programmes in order to improve their teaching competencies so that they become effective and competent teachers in the present educational environment.
Theoretical implications: The statistically validated methodological framework provides for capturing the perception of all stakeholders on the teaching competencies among the faculty members of Agricultural Universities in India, and offers a scope for scaling up the study for similar educational setting in the region.
Originality/value: The perception of students and administrators was also considered along with the self-perception of faculty about the relevance and knowledge levels of teaching competencies. 相似文献

Colleges of Business (COBs) have experienced high growth rates in the past decade and many colleges are imposing minimum grade point average (GPA) requirements for students to enter or remain in the college. A primary reason for this requirement may be the belief that students with high GPAs are more inclined to demonstrate higher‐order cognitive skills (HOCS) than students with low GPAs. It is not clear whether the link is valid. This study hypothesizes that students with high GPAs who are taught in the same way as students with lower GPAs will have higher perceptions of improved HOCS. We conducted an experiment in which students, with varying GPAs, at three large universities primarily used multimedia instructional materials. We obtained the students' perceptions of their improved HOCS from their responses to a survey. A regression analysis of the data reveals that the relationship between GPAs and students' perceived improvement in HOCS is significant (p < .001). We conclude the study by recommending that (a) it is critical to use research methodologies to evaluate perceived and actual learning improvements, (b) COB policies to implement GPA restrictions on admission are worthwhile, and (c) case studies need to be used much more frequently in undergraduate COB classes. 相似文献

This part of the article continues the discussion of the aerodynamic characteristics of airfoils presented in the previous
part and extends it to wings at subsonic speeds. The effects of highlift devices and spoilers are considered and their application
indicated. The effects of wing sweep and finiteness of aspect ratio are analyzed. 相似文献

Public awareness of airplane safety is very high due to the spectacular nature of airplane accidents. Partly as a result,
civil airplane operations are tightly regulated at all levels from design to operation and maintenance. Scheduled airline
operations have thus been able achieve a very high level of safety. In this article we quantify the safety of flight operations
and indicate the design concepts like fail safety and safe life used in achieving a high level of safety. As an illustration,
we consider the safety of a flight of a twin engine airplane in the event of one engine failure. 相似文献

Studies have shown that it is difficult for people to deal with multicriteria decision‐making situations. Information technology tools such as decision‐support systems and expert systems have been developed in order to help them in such situations. Another tool that has been identified as helping managers understand complex engineering decision‐making situations is multimedia instructional materials. This research investigates the perceptions of business versus engineering students on improvement of their higher‐level cognitive skills when they participated in a multimedia‐based case study that used an expert system to model a complex engineering and technical problem. Two groups of students, business and engineering, participated in an experiment, where they analyzed the case study and made their recommendations. Two questionnaires measured their perceptions on the improvements achieved on different constructs. A structural equations model was developed in order to test the research hypotheses with business students being the experimental group and the engineering students as a control group. The major findings are no significant relationship between student major and higher‐order cognitive skills improvement, business students perceived more higher‐order skills improvement compared to engineering students, both groups perceived an improvement in learning‐driven factor, and business students valued learning‐driven factors more compared to engineering students. These results show that multimedia instructional materials were perceived to be very useful in making multicriteria engineering and technical decisions. 相似文献

Conclusion Instrumented small airplanes for research and development of airplanes and other flight vehicles offer a viable method of
study which is very cost-effective. The studies could also be extended into control and navigation. Development of small airplanes
for various surveillance applications can also be effectively handled by this route. It is expected that the methods and instruments
developed in the present context will find wider applications in future. 相似文献
