The authors examined the relationships among students' levels of boredom, boredom coping strategies, epistemic curiosity, and graded performance regarding mathematics lessons, with the intention to explore the mediating roles of boredom coping strategies and epistemic curiosity in the relationship between the level of boredom and graded performance. A total of 557 students from a small city located in the Western Black Sea region of Turkey voluntarily participated in the study. Of them, 211 enrolled in an Anatolian high school and 346 enrolled in a science high school. Results showed that the level of boredom, boredom coping strategies, epistemic curiosity, and graded performance were significantly related to each other. Results also showed that deprivation-type epistemic curiosity and interest-type epistemic curiosity played significant mediating roles in the relationship between the level of boredom and graded performance. Notably, the mediating roles of interest-type epistemic curiosity and deprivation-type epistemic curiosity differed across gender groups. 相似文献

Background:
The ultra-large von Willebrand factor (vWF) multimers are very active and must be degraded by ADAMTS13 for optimal activity. A severe functional deficiency of ADAMTS13 has been associated with thrombotic thrombocytopenic purpura. The correct interpretation of patient vWF and ADAMTS13 plasma levels requires an understanding of the biological variation associated with these analytes. In the present paper, we aimed to determine the biological variation of ADAMTS13 and vWF in human adults.Materials and methods:
Blood samples were collected weekly from 19 healthy subjects for 5 consecutive weeks. vWF activity and antigenicity were determined using aggregometric and immunoturbidimetric methods. ADAMTS13 antigenicity and activity were determined by ELISA.Results:
The within-subject biological variations for vWF activity and antigenicity were 8.06% and 14.37%, respectively, while the between-subject biological variations were 18.5% and 22.59%, respectively. The index of individuality for vWF activity was 0.44, while vWF antigenicity was 0.64. Similarly, ADAMTS13 activity and antigenicity within-subject biological variations were 12.73% and 9.75%, respectively, while between-subject biological variations were 9.63% and 6.28%, respectively. The ADAMTS13 indexes of individuality were 1.32 and 1.55, respectively.Conclusion:
We report high biological variation and individuality in vWF antigenicity and activity levels. However, ADAMTS13 antigenicity and activity displayed high biological variation, but low individuality. Thus, population-based reference intervals may be useful for monitoring ADAMTS13 antigenicity and activity, but not for vWF, which displays high individuality. These findings should be considered when determining the reference interval and other clinical variables associated with ADAMTS13 and vWF levels. 相似文献3.
The purpose of this study is to examine the effect of creative drama-based instruction on seventh graders’ science achievements
in the ecology and matter cycles unit and their attitudes toward science. The study is an experimental study carried out in
one of the public elementary schools in Turkey during 2005–2006 schooling year. An ecological concept achievement test was
developed and administered to 45 students in two classes (as control and experimental group) of an elementary school before
and after the treatment. The experimental group received creative drama-based instruction and the control group received traditional
instruction. A guiding instruction material which contains six lesson plans in the subject was constructed for the teacher
to administer creative drama-based instruction. The topics of ecosystems and matter cycles were taught to the both of groups
for 3 weeks. A science attitude test was administered to both groups before and after the treatment. The results revealed
a statistically significant difference between the mean scores of the both groups with respect to achievement in the ecology
concepts and median of the attitudes toward science in favour of the experimental group after the treatment. 相似文献

When the small angle approximation is not made, the exact solution of the simple pendulum is a Jacobian elliptic function
with one real and one imaginary period. Far from being a physically meaningless mathematical curiosity, the second period
represents the imaginary time the pendulum takes to swing upwards and tunnel through the potential barrier in the semi-classical
WKB approximation1 in quantum mechanics. The tunneling here provides a simple illustration of similar phenomena in Yang-Mills theories describing
weak and strong interactions. 相似文献

There are standard proofs showing there can be no monopole electromagnetic radiation and no dipole gravitational radiation.
We supplement these with a global topological argument for the former, and a local argument based directly on the principle
of equivalence for the latter. 相似文献

The author estimates the impacts of the local rate of unemployment and the Great Recession on the quit and graduation rates of the U.S. construction trade apprentices over the 2001–2014 period. Trade union participation in training sponsorship had a strong influence on attrition rates. The impacts of the business cycle and the Great Recession on the attrition rate also varied across sponsor types. During downturns, apprenticeship duration of the quitters in union-employer jointly sponsored programmes was longer, suggesting that the trainees were able to stay with the programme as jobs become scarcer. However, during the Great Recession the quit hazard among these trainees increased, which indicates declining long-term career prospects. In contrast, apprentices in unilateral multiple-employer programmes dropped out at faster rates during the downturns, except during the Great Recession. The increase in the staying power of the quitters in employer-only programmes during the Great Recession is a puzzle. The eventual probability of cancellation was lower among the union-employer joint programmes than in the employer-only programmes, although the difference narrowed down during the Great Recession. 相似文献

The purpose of this research is to show how wearable eye-tracking technology can be employed to assess and enhance classroom management skills by analyzing the instructors’ eye movements in a university. The research also aimed to evaluate the instructors’ gestures by recording with a video camera synchronized with the eye-tracking data. The findings showed that the wearable eye tracker gives informative feedback about the visual attention of the instructors. It provided meaningful data by video recordings and Retrospective Think Aloud sessions. Also, it demonstrated how the instructors interacted with classroom technology. Consequently, the wearable eye tracker and video-camera together could be used by Teaching/Learning Centers to improve instructors’ classroom management skills and to observe their interaction with instructional technologies.

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
