In the article ‘Factors predicting online university students’ use of a mobile learning management system (m-LMS)’, Joo, Kim and Kim (Educ Technol Res Dev 64:611–30, 2016) explain actual usage of a mobile learning management system by looking at continuance intention, satisfaction, perceived usefulness, perceived ease of use and expectation confirmation. Perceived usefulness seems to play a pivotal role. In this reaction, it is argued that their study can be approached from to complementary and interacting perspectives: context and agency.

Publications on anatomy in medical education appear to be largely anecdotal. To explore this, we investigated the literature on anatomy in medical education, aiming first to evaluate the contribution of the literature on anatomy in medical education to "best evidence medical education" (BEME) and second to evaluate the development of this literature toward more "best evidence" between 1985 and 2009. Four databases were searched for publications on anatomy in medical education published between 1985 and 2009, resulting in 525 references. Hundred publications were characterized by five variables (journal category, paper subject, paper category, author perspective, and paper perspective). Statements from these publications were characterized by two variables (category and foundation). The publications contained 797 statements that involved the words "anatomy," "anatomical," or "anatomist." Forty-five percent of the publications contained no explicit research question. Forty percent of the statements made were about "teaching methods" and 17% about "teaching content," 8% referred to "practical value," and 10% to "side effects" of anatomy education. Ten percent of the statements were "positional," five percent "traditional," four percent "self-evident," and two percent referred to "quality of care." Fifty-six percent of the statements had no foundation, 17% were founded on empirical data, and 27% by references. These results substantiated the critical comments about the anecdotal nature of the literature. However, it is encouraging to see that between 1985 and 2009 the number of publications is rising that these publications increasingly focus on teaching methods and that an academic writing style is developing. This suggests a growing body of empirical literature about anatomy education. 相似文献

Problem‐based learning (PBL) modified for distance education (PBDiL = Problem‐Based Distance Learning) has been used for teaching energy issues at Uppsala University, Sweden. Collaborative learning in groups of seven to eight students was enabled by computer communication and enhanced the use of Internet. Two different teaching methods have been tried and are compared, both being influenced by methods used in conventional face‐to‐face PBL. The problem presentation was entirely built on pictures, and examination through student reports was successful. A student remark, ‘I study on my own but yet not alone’ shows the importance of social contact. 相似文献

Changes in the relation between cognitive and metacognitive skills during the acquisition of expertise 总被引:2,自引:0,他引:2

This paper focuses on the transformation of general metacognitive skills of novices into domain-specific regulatory procedures of experts, and the relation of those skills to intelligence. Research has shown that the general metacognitive skills of novices, although partly correlated to intelligence, additionally contribute to learning outcome on top of intelligence. The metacognitive skills of experts appear to be domainspecific and unrelated to intelligence. Two experiments were conducted. The objective of the first experiment was to confirm and generalize these earlier results concerning the relation of intellectual ability, metacognitive skillfulness and learning of novices vs. advanced subjects. The objective of the second experiment was to investigate this relation under different conditions of task complexity. It was hypothesized that advanced subjects would regress to more novice-like behavior under very complex learning conditions (i.e., general metacognitive skills and intelligence would re-appear as combined predictors of learning outcome). On the other hand, low intelligent novices, irrespective of their metacognitive skillfulnes, were expected to fail on very complex problems. Results partly confirmed these hypotheses. Implications for the conditions under which metacognitive experiences should be implemented, are being discussed. 相似文献

Professional knowledge is an important source of science teachers' actions in the classroom (e.g., personal professional content knowledge [pedagogical content knowledge, PCK] is the source of enacted PCK in the refined consensus model [RCM] for PCK). However, the evidence for this claim is ambiguous at best. This study applied a cross-lagged panel design to examine the relationship between professional knowledge and actions in one particular instructional situation: explaining physics. Pre- and post a field experience (one semester), 47 preservice physics teachers from four different universities were tested for their content knowledge (CK), PCK, pedagogical knowledge (PK), and action-related skills in explaining physics. The study showed that joint professional knowledge (the weighted sum of CK, PCK, and PK scores) at the beginning of the field experience impacted the development of explaining skills during the field experience (β = .38**). We interpret this as a particular relationship between professional knowledge and science teachers' action-related skills (enacted PCK): professional knowledge is necessary for the development of explaining skills. That is evidence that personal PCK affects enacted PCK. In addition, field experiences are often supposed to bridge the theory-practice gap by transforming professional knowledge into instructional practice. Our results suggest that for field experiences to be effective, preservice teachers should start with profound professional knowledge. 相似文献

The context of this study were research and development projects in Dutch secondary education, particularly funded by government to combine practice-based research with school development goals for inquiry-based culture. Aiming at better understanding of the strategic role that school leaders play in embedding inquiry-based practices in schools, the research question of this study was to explore to what extent and how do school leaders use the opportunity of participating in funded research and development projects for encouraging and integrating inquiry-based practices in their schools? Differences concerning the integration of inquiry-based working in the school as professional learning community were examined, distinguishing between school leaders’ strategies of capacity building. Twenty-eight school leaders of Dutch secondary schools, involved in nineteen projects, were interviewed retrospectively. Analyses showed the majority of the school leaders to be convinced that inquiry-based working is important for their schools’ development as a professional community. Their strategies for achieving school level project significance differed in school leaders’ successive attention on personal or interpersonal capacity building with regard to inquiry-based practices. Moreover, while some school leaders were actively involved with capacity building right from the start of the research and development projects projects, almost two-third of the school leaders developed interest in inquiry-based practices during the projects and started to enact in the final year of the project. In discussing the results, it is proposed that the interaction of strategy and context needs further study, for instance to inform peer learning among school leaders that are novice and experienced in inquiry-based practices as a means to develop the school as a professional learning community. 相似文献

IntroductionLeukolysis-related pseudohyperkalemia due to preanalytical procedures may lead to erroneous (or absence of) treatment based on an invalid lab test result. We aimed to obtain a leukocyte threshold above which leukolysis-related pseudohyperkalemia becomes clinical relevant. Secondly, temporal dynamics of treatment-induced leukocyte decrease were studied to allow tailored implementation of laboratory information system (LIS) decision rules based on the leukocyte threshold to avoid leukolysis-related pseudohyperkalemia.Materials and methodsPotassium results of AU5811 routine chemistry (Beckman Coulter, Brea, California, USA) and iStat point of care (POC) (Abbott Diagnostics, Chicago, Illinois, USA) analysers were compared, the latter method being insensitive to leukolysis caused by pre-analytical procedures. Potassium results were combined with leukocyte counts obtained using a Cell-Dyn Sapphire haematology analyser (Abbott Diagnostics, Santa Clara, California, USA), resulting in 132 unique data triplets. Regression analysis was performed to establish a leukocyte threshold. The Reference Change Value (√2 x Z x √(CVa2 + CVi2)) was used to calculate maximum allowable difference between routine analyser and POC potassium results (deltamax + 0.58 mmol/L). Temporal analysis on the treatment-induced leukocyte decrease was performed by plotting leukocyte counts in time for all patients above the threshold leukocyte count (N = 41).ResultsEstablished leukocyte threshold was 63 x109/L. Temporal analysis showed leukocyte counts below the threshold within 8 days of treatment for all patients.ConclusionsBased on performed analyses we were able to implement LIS decision rules to reduce pseudohyperkalemia due to preanalytical procedures. This implementation can contribute to a reduction in erroneous (or absence of) treatments in the clinic. 相似文献

Red lake pigments and dyes used in works of art were characterized by microspectrofluorimetry, a new tool in the field of cultural heritage. Emission and excitation spectra were obtained with high spatial resolution (8–30 μm) in cross-sections from paintings by Vincent van Gogh and Lucien Pissarro and from millenary Andean textiles. The fluorophores were identified by comparing their spectra with those from historic reconstructions assembled in a database. In the paints, purpurin and eosin lakes were detected. In the Paracas and Nasca textiles, dated from 200 B.C. to A.D.1476, purpurin and pseudopurpurin were the red dyes used. Carminic acid was detected in textiles dated close to the Inca Empire, A.D. 1000–1476. The results obtained with this new technique were confirmed and are in agreement with those obtained with conventional methods, requiring microsampling, such as HPLC-DAD-MS and SEM-EDX. 相似文献
