IntroductionTo interpret test results correctly, understanding of the variations that affect test results is essential. The aim of this study is: 1) to evaluate the clinicians’ knowledge and opinion concerning biological variation (BV), and 2) to investigate if clinicians use BV in the interpretation of test results.Materials and methodsThis study uses a questionnaire comprising open-ended and close-ended questions. Questions were selected from the real-life numerical examples of interpretation of test results, the knowledge about main sources of variations in laboratories and the opinion of clinicians on BV. A total of 399 clinicians were interviewed, and the answers were evaluated using a scoring system ranked from A (clinician has the highest level of knowledge and the ability of using BV data) to D (clinician has no knowledge about variations in laboratory). The results were presented as number (N) and percentage (%).ResultsAltogether, 60.4% of clinicians have knowledge of pre-analytical and analytical variations; but only 3.5% of them have knowledge related to BV. The number of clinicians using BV data or reference change value (RCV) to interpret measurements results was zero, while 79.4% of clinicians accepted that the difference between two measurements results located within the reference interval may be significant.ConclusionsClinicians do not use BV data or tools derived from BV such as RCV to interpret test results. It is recommended that BV should be included in the medical school curriculum, and clinicians should be encouraged to use BV data for safe and valid interpretation of test results. 相似文献

This study is an investigation of the effects of death education on children and their understanding of death. The participants of this study were eighty 5- and 6-year-olds who were enrolled in a suburban kindergarten in Korea. To examine the level of children's understanding of death, researchers interviewed each child in both the control and experimental groups. After the interview, researchers provided an intervention (11 educational activities) to the experimental group. No educational intervention was provided to the control group. Researchers re-interviewed children in both groups after the treatment. The overall mean score of the experimental group was significantly higher than that of the control group on all five categories of the death concept: causality, old age, irreversibility, finality, and inevitability. Implications regarding how death education can be approached in early childhood settings are also discussed. 相似文献

This survey-based quantitative study investigates 310 Turkish preschool teachers’ views about classroom management, using the following six models of disciplinary strategy: behavioral change theory, Dreikurs’ social discipline model, Canter’s assertive discipline model, the Glasser model of discipline, Kounin’s model, and Gordon’s teacher effectiveness training (TET) model. Data were collected through a demographic information form and the Discipline Strategies Questionnaire. The results showed that the participant teachers usually agreed with items that reflected a child-centered approach to classroom management. Also, the respondents’ views of Dreikurs’ social discipline model and Gordon’s TET model differed according to their gender. The teachers’ views related to behavioral change theory and Gordon’s TET also varied markedly, depending on the ages of the children they taught. 相似文献

This study investigates the effect of the science writing heuristic (SWH) approach on the quality of prospective science teachers’ (PSTs) argumentative writing and their understanding of the components of argumentation in the SWH approach and their own learning. Ten SWH approach activities were implemented during the semester. The study was carried out with 31 PSTs. A case study design was used. Data included the SWH approach’s grading rubric and semistructured interviews. While the ANOVA and Bonferroni tests were used to analyze the SWH approach’s grading rubric, content analysis was used to analyze the semistructured interviews conducted with 12 PSTs. The ANOVA results showed a statistical difference among the writing performance of the PSTs (F = 14.493, p < 0.01). The findings gathered from the interviews revealed that the quality of the argumentative writing and research skills of the PSTs increased over time. The PSTs made explicit associations among their beginning questions, data and observations, and claims and evidence, and they made distinctions between their data, observations, and evidence. Multiple representations played an important role in providing evidence to support claims. Moreover, the process of negotiation helped PSTs learn more effectively, and they believed that the argument-based inquiry lab was beneficial to their learning and their future vocational careers as teachers. 相似文献

Introduction
Measurements of blood ethanol concentrations must be accurate and reliable. The most important factors affecting blood ethanol stability are temperature and storage time. In this study, we aimed to compare ethanol stability in plasma samples at -20 °C for the different storage periods.Materials and methods
Blood samples were collected from intoxicated drivers (N = 80) and initial plasma ethanol concentrations were measured immediately. Plasma samples were then stored at -20 °C and re-assessed after 2, 3, 4, or 5 months of storage. Differences between the initial and stored ethanol concentrations in each group (N = 20) were analyzed using Wilcoxon matched-pairs test. The deviation from the initial concentration was calculated and compared with Clinical Laboratory Improvement Amendments (CLIA’88) Proficiency Testing Limits. Relationships between the initial concentrations and deviations from initial concentrations were analyzed by Spearman’s correlation analysis. For all statistical tests, differences with P values of less than 0.05 were considered statistically significant.Results
Statistically significant differences were observed between the initial and poststorage ethanol concentrations in the overall sample group (P < 0.001). However, for the individual storage duration groups, analytically significant decreases were observed only for samples stored for 5 months, deviations from the initial concentrations exceeded the allowable total error (TEa). Ethanol decreases in the other groups did not exceed the TEa.Conclusion
According to our results, plasma ethanol samples can be kept at -20 °C for up to 3-4 months until re-analysis. However, each laboratory should also establish its own work-flow rules and criterion for reliable ethanol measurement in forensic cases.Key words: preanalytical phase, ethanol, stability, storage temperature 相似文献68.

A short 12-item version of the Career Adapt-Abilities Scale–Short Form (CAAS-SF) was validated across three different age groups in the Turkish context. Scale scores demonstrated adequate to high internal consistency and 4-week test–retest reliability, good fit with the original four-factor model, factorial invariance across gender and age groups, strong convergence with the 24-item version, negative associations with trait anxiety and work stress, and positive associations with career decision self-efficacy. It was concluded that the Turkish version of the CAAS-SF appears to be a valid and reliable measure for assessing career adaptability and using it in career education and counseling process. 相似文献

The purpose of this study was to examine the correlation of different variables with information retention in guided 3D virtual learning environments by employing three experimental designs. In each experiments, different participants were included in the same population and different variables were considered. Information retention test, flow, presence, engagement scales were used as data collection tools. Namely measures of flow, presence and engagement were examined to see their correlation with retention in experiment 1, 2 and 3. As a result, not the total score of flow but focused attention, enjoyment and skill dimensions has a weak but significant correlation with information retention, while the challenge has a moderate and significant negative correlation. In the second experiment, retention had a significant, low-level relationship with teaching presence and cognitive presence, but it did not have a similar relationship with social presence. In the third experiment, information retention significantly correlated with affective and cognitive engagement, but not with behavioral engagement. Although the three studies’ participants were from the same population, It was seen that the differences in the level of relationship between information retention and the variables studied in each study. Nevertheless, it was found that the levels of flow, presence and engagement of students are important for information retention in a guided 3D virtual learning environment. The study is thought to guide researchers to design 3D virtual learning environments for different purposes, considering these variables. 相似文献

Math is a subject in which students are generally not very interested and are unsuccessful compared to other courses. It has been suggested that digital stories designed for educational purposes could be used to prevent students’ lack of interest and failure in this subject. However, designing stories that are fit for purpose is important if the use of digital stories is to be successful. The purpose of this study is to investigate pre-service teachers’ opinions about how they utilized the steps of Gagne’s model while designing digital stories for math lessons. The participants in the study were 49 pre-service teachers studying at a Math Department at a Turkish state university in the spring term of the 2014–2015 academic year. The Pre-service Teachers’ Opinion Form and a Personal Information Form, both developed by the researchers, were used as data collection tools in the study, in which the qualitative method was adopted. Content analysis was utilized to analyze the data collected through open-ended questions. When the findings were examined it was seen that pre-service teachers had designed digital stories in which they often chose to attract attention by creating interesting characters in the “gaining students’ attention” step of Gagne’s teaching model, that the main character stated the objectives/topic in the story precisely in the “informing students of the objectives” step, and that the characters created repeated the previous topic in the “stimulating recall of prior learning” step. In the current study, the integration of digital story design into lesson plans in accordance with Gagne’s model was carried out and pre-service teachers’ opinions about their experiences of this process were investigated. 相似文献
