This qualitative–case study examined how portfolio and portfolio assessment were perceived by prospective teachers. The participants
were 23 prospective teachers from seven different teaching areas from a Turkish university. A semi-structured individual interview
was conducted. The interview schedule included 15 open-ended questions. The main results emerged from content analysis were
that prospective teachers perceived portfolio as a learning and an assessment tool. Further, they believed that portfolio
was complementary rather than an alternative assessment method to traditional assessment procedures. 相似文献

Introduction:
The aim of this study was to investigate whether serum levels of interleukin-1β (IL–1β) has any possible correlation on inflammatory parameters such as C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and fibrinogen concentration in patients with familial Mediterranean fever (FMF) patients during attack-free period.Materials and methods:
The serum levels of IL-1β, as an indicator of cytokines status, and the acute phase response proteins, CRP, ESR and fibrinogen levels were evaluated in 35 attack-free patients with FMF and 25 healthy volunteers.Results:
Serum IL-1β levels were significantly higher in patients with FMF than control subjects (P = 0.018). There was no statistically significant difference in the serum levels of ESR, CRP and fibrinogen between two groups (P = 0.181, P = 0.816, P = 0.686, respectively). There was a significant correlation between IL-1β and CRP (r = 0.513, P = 0.002) values of FMF group.Conclusions:
In conclusion, our results confirm the presence of increased IL-1β levels in FMF patients during attack-free period. Serum IL-1β values seems to correlate with CRP levels. The elevation of IL-1β levels may be important in monitoring subclinical inflammation of attack free period in FMF patients. 相似文献33.

State Dependent Riccati Equation (SDRE) methods have the considerable advantages over other nonlinear control methods. However, stability issues can be arisen in SDRE based control system due to the lack of the global asymptotic stability property. Therefore, the previous studies have usually shown that local asymptotic stability can be ensured by estimating a Region of Attraction (ROA) around the equilibrium point. These estimated regions for stability may become narrow or the condition to keep the states in this region may be very conservative. To resolve these issues, this paper proposes a novel SDRE method employing an update algorithm to re-estimate the ROA when the states tend to move out of the stable region. The tendency is checked using a condition which is developed based on a new theorem. The theorem proves that it is possible to redesign the previous ROA with respect to the current states lying close to its boundary for ensuring the “non-local” stability along the trajectory without the need of solving SDRE at each time instant, unlike the standard SDRE approach. Therefore, the new theorem is now able to enhance the stability of the SDRE based closed-loop control system. The feasibility of the proposed SDRE control method is tested in both simulations and experiments. A validated 3-DOF laboratory helicopter is used for experiments and the control objective for the helicopter is to realise a preplanned movement in both elevation and travel axes. The results reveal that the proposed SDRE approach enables the controlled plant to track the desired trajectory as satisfactorily as the standard SDRE approach, while only solving SDRE when needed. The proposed SDRE method reduces the computational load for practical implementation of the control algorithm whilst ensuring the stability over the operational region. 相似文献

This study has two aims. The first one is to reveal the science teacher candidates’ misconceptions about the density by using a four-tier diagnostic test, and the second one is to determine to what extent science teacher candidates have scientific knowledge, lack of knowledge, and misconceptions about the density. In order to achieve these aims, a four-tier density diagnostic test was developed with the KR-20 reliability coefficient of 0.753 based on the correct answers, and the KR-20 reliability coefficient of 0.528 based on the misconceptions. To determine the misconceptions about the density with the developed test, data were collected from a total of 470 science teacher candidates from seven different universities in Turkey. With the developed four-tier diagnostic test, 48 different misconceptions were revealed. The results of the research showed that about one fourth of science teacher candidates had a misconception about the density and that the ratio of six of the resulting misconceptions was over 10%. It may be suggested that this study conducted on science teacher candidates should also be conducted on middle and high school students and experimental studies should be carried out to eliminate the misconceptions that emerged in this study.

There are unusual elements in this essay. It is a coconstructed intercultural narrative about spaces, places, people, and ideas, about their influence on us and our academic journeys, separately and together. Each narrative considers the intercultural footpaths and bridges that have connected us to one another and to others in the Central States Communication Association (CSCA) and the Intercultural Communication (IC) interest group. 相似文献

The study of intercultural communication (IC) has a long history in the Central States Communication Association (CSCA). Some of the earliest work in IC has come from universities in the CSCA region, such as Indiana University (William Starosta) and University of Minnesota (Vernon Jensen and Rosita Albert). Since the inception of the Intercultural Communication Interest Group within CSCA in the early 1990s, IC scholars have contributed immensely to the discipline by studying different aspects of the relationship between communication and culture. Several active IC scholars present their recollections of the development of IC research in this issue. 相似文献

This article draws on the Millennium Cohort Study (MCS) to examine parent ratings of social, emotional and behavioural difficulties and prosocial behaviour in pre‐ and mid‐adolescents. A series of mixed‐design ANOVAs yielded interesting results. Parent ratings of emotional difficulties in girls increased as they moved from pre‐ to mid‐adolescence whereas for boys the reverse was found. Peer problems were found to be on the rise, whereas prosocial skills decreased for 14‐year‐olds. Most importantly, significant associations were found between socio‐economic measures (that is, family income and parent education) and ratings across the domains of the Strengths and Difficulties Questionnaire, highlighting the socio‐economic specificity of behaviour and well‐being in adolescents. These findings have significant implications for understanding trends in young people's social behaviour and emotional well‐being from pre‐ to mid‐adolescence within their socio‐economic context. 相似文献

This study aimed to analyze environmental education research (EER) in Turkey conducted in Grades K‐8 and published over the years 1997–2007. Due to the fact that there had been no systematic reviews of EER in Turkey prior to this time period, it was more appropriate to explore the implications of the results of this review for research policies and practices than for educational policies and practices in Grades K‐8. A substantial search of the international and national literature revealed 53 studies that fit the time frame and study characteristics. Three analyses of these studies were undertaken: (a) features of the research method; (b) socio‐demographic characteristics of the subjects; and (c) components of environmental literacy assessed. Three charts were constructed to support these analyses; e.g., one for each analysis. For analysis (a), quantitative surveys were the most common method. For analysis (b), greater attention was paid to the age, grade level, gender and residence of participating students. For analysis (c), greater attention was paid to knowledge of ecology and natural history, and knowledge of environmental problems and issues, less attention was paid to components of affect, and very little attention was paid to socio‐political‐economic knowledge, cognitive skills and environmentally responsible behavior. 相似文献

While plagiarism has been a growing problem in higher education for a long time, the use of the Internet has made this increasing problem more unmanageable. In many countries, this problem has become a matter of discussion, and higher education institutions feel obliged to review their policies on academic dishonesty. As part of these efforts, the study aims to examine the tendencies of teacher candidates to plagiarise using the Internet, factors affecting their tendencies and the reasons for plagiarism. In this context, a questionnaire was administered to a total of 386 first- and fourth-grade college students at a college of education. The data were analysed using frequencies, percentages, the Mann–Whitney U test and Kruskal–Wallis one-way analysis of variance. The findings revealed that the teacher candidates had, to some extent, a tendency to plagiarise using the Internet by copying material or using the same assignment in different courses. Gender, department and length of computer use were found to be significant factors affecting their tendencies to plagiarise using the Internet. Time constraints, workload and difficulty of the assignments/projects were indicated as among the major reasons for tendencies towards Internet plagiarism. 相似文献
