How many scholarly research articles are there in existence? Journal articles first appeared in 1665, and the cumulative total is estimated here to have passed 50 million in 2009. This sum was arrived at based on published figures for global annual output for 2006, and analyses of annual output and growth rates published in the last decade. 相似文献

It is important for teachers of mathematics to know how pupils react to certain mathematical situations and what these reactions imply, in order to design more effective instructional environments based on their learning needs. This study reports the development processes of a digital learning tool (Learning Tool for Elementary School Teachers (L‐TEST)) that shows children's mathematical thinking for the ages of 4–11 years across certain problem situations. L‐TEST is designed as a support tool to be used in teacher education. A case‐based instructional model was used in designing the instructional tool. Video recordings were digitised to provide a rich environment where learners observe exemplary cases. These exemplified videos included children's mathematical development in the subjects of numbers and shapes, combined with discussions in line with the current research findings. Finally, a usability test for the learning tool was carried out. 相似文献

The aim of this study was to compare the musculature activity and kinematics of knee and hip joints during front and back squat with maximal loading. Two-dimensional kinematical data were collected and electromyographic activities of vastus lateralis, vastus medialis, rectus femoris, semitendinosus, biceps femoris, gluteus maximus and erector spinae were measured while participants (n = 12, 21.2 ± 1.9 years old) were completing front and back squat exercises with maximum loading. Paired sample t-test was used for comparisons between two techniques. Results showed that the electromyographic activity of vastus medialis was found to be greater in the front squat compared to the back squat during the ascending phase (P < 0.05, d = 0.62; 95% CI, ?15.0/?4.17) and the whole manoeuvre (P < 0.05, d = 0.41; 95% CI, ?12.8/?0.43), while semitendinosus (P < 0.05, d = ?0.79; 95% CI, 0.62/20.59) electromyographic activity was greater in the back squat during the ascending phase. Compared to the front squat version, back squat exhibited significantly greater trunk lean, with no differences occurring in the knee joint kinematics throughout the movement. Results may suggest that the front squat may be preferred to the back squat for knee extensor development and for preventing possible lumbar injuries during maximum loading. 相似文献

Training paraprofessionals such as teachers is one of many significant challenges facing Afghanistan??s educational system. This case study focuses on the innovations offered in that regard by BRAC, a large NGO based in Bangladesh that brought its many years of development experience to Afghanistan in 2002 and established itself there as the premier change agent on multiple developmental fronts. Through the use of structured and semi-structured interviews with stakeholders, classroom observations, and extensive document analysis, the authors conclude that by successfully modifying its teacher training programme in Bangladesh, BRAC has been able to develop an approach to teacher training in Afghanistan that may become a showcase example of effective South-South partnership in education. The article concludes by urging adoption of BRAC??s innovations in teacher training and recruitment by other developing nations facing similar challenges. 相似文献

Information explosion, development and applications of ICTs, changing dynamics of information users, and evolving trends in library and information services have promoted the discussion of continuing education (CE) in Library and Information Science (LIS) domain. ICTs are increasingly changing the landscape of libraries and challenging the traditional prevailing roles of LIS professionals. LIS professionals find it hard to remain in context in this technological era. They require the new set of skills and knowledge to address the challenges and issues of their professional life.The purpose of this study was to explore the opinions of LIS professionals to make an assessment about CE needs and the role of library schools to address these needs. The study opted sequential mixed methods of research. In first phase, an online survey was conducted to meet the objectives of the study. Data was collected by using a structured questionnaire. A total of 144 responses (70% male and 30% female) were received. In 2nd phase, a focus group was conducted to collect the qualitative data. The meta inferences were drawn on the basis of inferences of both QUAN and QUAL strands. The findings of the study revealed that respondents perceive a very active and instrumental role of LIS schools in their continuing education. Workshops, post-master certificate, and post-graduate diplomas were preferred formats of continuing education programs. The respondents preferred week long and 1–6 months long CE programs. In terms of the timings, weekends programs were most preferred. The respondents recommended that course instructor should be based on the contents of the course and a blend of teaching faculty and practitioners may be productive. The study also identified core areas of CE offerings.The findings of the study are helpful for LIS schools, professionals, trainers, funding bodies and policy makers. The study has the potential to bridge the gap by providing insight about the CE needs and recommend the concrete suggestions to act upon. 相似文献

AbstractThe current study aimed to examine differences in ecological values between Indonesian and Korean preservice science teachers. Fifteen items from revised-New Ecological Paradigm based on value orientations were used as the research instrument. Two hundred seventy-three preservice science teachers participated in the study. Rasch analyses of dimensionality, item fit, and differential item functioning were used to explore the validity of the instrument. The independent-sample T-test and Pearson’s correlation test were utilized to compare data from the two countries. Preservice science teachers from the two different countries showed significant differences in only one of the three value orientations, which is egoistic value. Relationships among cultural, educational, and economic factors, as well as environmental values in these countries are discussed to fully explore the findings. 相似文献
