This study investigated profiles of South Korean early childhood educators' teacher self-efficacy and contributing factors to teacher self-efficacy. The contributing factors were examined with a focus on early childhood education (ECE) center climate and depression severity in teachers as well as teacher and classroom characteristics. The results suggested that Korean early childhood educators' teacher self-efficacy was multi-dimensional, and each dimension had unique predictors. ECE center climate emerged as the most significant contributor to all teacher self-efficacy domains. Depression severity in teachers was associated with teacher self-efficacy but the facets of association were different according to the attributes of the efficacy domains. Instructional efficacy, which directly pertains to teaching professions, was not associated with depression in teachers. On the other hand, teacher self-efficacy domains containing affective aspects, such as creating positive social contexts and parental involvement and decision-making, were vulnerable to depression severity. 相似文献

As the influences of science and technology on its national economy have increased, each country has devised various funding programs for research and development (R&D) projects. Numerous studies have been conducted to evaluate the performance of such R&D projects. In most studies, the performances were measured in terms of an ordinal Likert scale, but they were treated as continuous variables. Much important information can be buried when a categorical Likert scale is treated as continuous variable. In this paper, we treat Likert scales as categorical and apply quantification method II to analyze the relationship between short- to mid-term performance factors and long-term impact factor of R&D projects. We apply the proposed approach to the survey data obtained from the Science and Technology Promotion Fund in Korea. The results of this paper are expected to contribute to a better understanding of the impact of R&D funding. 相似文献

This study aims to explore the impact of early childhood educators’ meta-cognitive knowledge on the quality of their childcare curriculum implementation, and to gain insights regarding successful problem-solving strategies associated with early education and care. Early childhood educators’ implementation of general problem-solving strategies in real educational settings has not previously been studied, even though providing early education and care is a complicated ill-structured task requiring effective problem-solving strategies. The present study surveyed 166 South Korean early childhood educators regarding their meta-cognitive knowledge of five general problem-solving strategies (free production, analogy, step-by-step analysis, visualisation and combining) and childcare curriculum implementation. In general, strategic teachers provided high-quality childcare. Teachers preferred analogy most strongly among the five general problem-solving strategies, but step-by-step analysis was the most powerful predictor of quality of curriculum implementation. Among the five strategies, only three strategies (step-by-step analysis, free production and analogy) showed meaningful associations with quality of curriculum implementation. 相似文献

This study suggests a new erythrocyte sedimentation rate (ESR) measurement method for the biophysical assessment of blood by using a microfluidic device. For an effective ESR measurement, a disposable syringe filled with blood is turned upside down and aligned at 180° with respect to gravitational direction. When the blood sample is delivered into the microfluidic device from the top position of the syringe, the hematocrit of blood flowing in the microfluidic channel decreases because the red blood cell-depleted region is increased from the top region of the syringe. The variation of hematocrit is evaluated by consecutively capturing images and conducting digital image processing technique for 10 min. The dynamic variation of ESR is quantitatively evaluated using two representative parameters, namely, time constant (λ) and ESR-area (AESR). To check the performance of the proposed method, blood samples with various ESR values are prepared by adding different concentrations of dextran solution. λ and AESR are quantitatively evaluated by using the proposed method and a conventional method, respectively. The proposed method can be used to measure ESR with superior reliability, compared with the conventional method. The proposed method can also be used to quantify ESR of blood collected from malaria-infected mouse under in vivo condition. To indirectly compare with the results obtained by the proposed method, the viscosity and velocity of the blood are measured using the microfluidic device. As a result, the biophysical properties, including ESR and viscosity of blood, are significantly influenced by the parasitemia level. These experimental demonstrations support the notion that the proposed method is capable of effectively monitoring the biophysical properties of blood. 相似文献

Although historical changes in scientific ideas sometimes display striking similarities with students’ conceptual progressions, some scholars have cautioned that such similarities lack meaningful commonalities. In the history of evolution, while Darwin and his contemporaries often used natural selection to explain evolutionary trait gain or increase, they struggled to use it to convincingly account for cases of trait loss or decrease. This study examines Darwin’s evolutionary writings about trait gain and loss in the Origin of Species (On the origin of species by means of natural selection, or the preservation of favoured races in the struggle for life. D. Appleton, New York, 1859) and compares them to written evolutionary explanations for trait gain and loss in a large (n > 500), cross-cultural and cross-sectional sample (novices and experts from the USA and Korea). Findings indicate that significantly more students and experts applied natural selection to cases of trait gain, but like Darwin and his contemporaries, they more often applied ‘use and disuse’ and ‘inheritance of acquired characteristics’ to episodes of trait loss. Although the parallelism between Darwin’s difficulties and students’ struggles with trait loss are striking, significant differences also characterize explanatory model structure. Overall, however, students and scientists struggles to explain trait loss—which is a very common phenomenon in the history of life—appear to transcend time, place, and level of biological expertise. The significance of these findings for evolution education are discussed; in particular, the situated nature of biological reasoning, and the important role that the history of science can play in understanding cognitive constraints on science learning. 相似文献
