Comparison of test use and multiple-evaluation to test effectiveness of PBL in different grouping strategies

Yaman, Suleyman


Problem-based learning (PBL) involves the process of working toward the understanding or solution of a problem. In educational contexts, PBL provides meaningful problems to improve learning. This study aims to investigate the comparative effectiveness of the achievement test and of multiple evaluation methods, including test use, self, peer, and tutor-evaluation, in PBL environments. Different grouping strategies, specifically tutor- and student-based selection, are used to test effectiveness of the evaluation approaches. The study was conducted with 46 prospective teachers using an experimental design. For the purpose of the study, . . . t-test for independent groups and correlation analysis were used. The prospective teachers in the tutor-selected group were found to be more successful when the complete results of the evaluations were considered. The use of multiple evaluation methods revealed a significant difference between groups, whereas the approach using only the achievement test did not show any statistically significant difference Daha fazlası Daha az

Sumer M. | Misir A.F. | Telcioglu N.T. | Guler A.U. | Yenisey M.

Article | 2011 | Journal of Oral and Maxillofacial Surgery69 ( 5 ) , pp.1350 - 1354

Purpose The purpose of this study was to compare the heat generated from implant drilling using stainless steel and ceramic drills. Materials and Methods A total of 40 fresh bovine femoral cortical bone samples were used in this study. A constant drill load of 2.0 kg was applied throughout the drilling procedures via a drilling rig at a speed of 1,500 rpm. Two different implant drill types (stainless steel and ceramic) were evaluated. Heat was measured with type K thermocouple from 3 different depths. Data were subjected to the independent-sample t test and Pearson correlation analysis. The ? level was set a priori at 0.05. Results . . .The mean maximum temperatures at the depths of 3 mm, 6 mm, and 9 mm with the stainless steel drill were 32.15°C, 35.94°C, and 37.05°C, respectively, and those with the ceramic drill were 34.49°C, 36.73°C, and 36.52°C, respectively. A statistically significant difference was found at the depth of 3 mm (P = .014) whereas there was no significant difference at the depths of 6 and 9 mm (P > .05) between stainless steel and ceramic drills. Conclusion Within the limitations of the study, although more heat was generated in the superficial part of the drilling cavity with the ceramic drill, heat modifications seemed not to be correlated with the drill type, whether stainless steel or ceramic, in the deep aspect of the cavity. Further clinical studies are required to determine the effect of drill type on heat generation. © 2011 American Association of Oral and Maxillofacial Surgeons Daha fazlası Daha az

Ozkalayci N. | Zengin A.Z. | Turk S.E. | Sumer A.P. | Bulucu B. | Kirtiloglu T.

Article | 2011 | European Journal of Dentistry5 ( 2 ) , pp.210 - 214

Pulp stones are usually found in the pulp chamber. Radiographically, they appear as radiopaque structures in the pulp chambers or root canals of individual teeth. Generalized pulp stones throughout the dentition are usually associated with systemic or genetic disorders of the dentine. This report presents an unusual case of a 13-year-old girl with generalized pulp stones with clinically normal crowns. The patient's main complaint was a crossbite affecting all permanent canines. Radiographic examination revealed multiple pulp stones and several teeth with atypically shaped roots. Orthodontic treatment, gingivoplasty, and esthetic res . . .torations were performed, thus using a multidisciplinary approach to establish functionally and esthetically sound dentition Daha fazlası Daha az

Football is the most popular sport in the world. Foot morphology and foot preference are important factors in football player's performance. The aim of this cross-sectional study was to evaluate the foot morphology of elite football players with different foot preferences. 407 male football players participated in this study. 328 of them preferred their right foot, while 79 of them preferred the left one. Eleven anthropometric measurements were taken from each foot with standard anthropometric methods. Foot length, T1, T2, T3, T4 and T5 lengths, foot circumference of right and left feet and right foot width of right foot preference . . .group were higher than those of left foot preference group, which is statistically significant (p < 0.05). Left foot measurements of right foot preference group were interestingly higher than those of the right side. It was suggested that these data may be useful to define the foot morphology of elite football players. © 2011 Academic Journals Daha fazlası Daha az

Dyadic Green's function study of band structures of dispersive photonic crystals

Ayaz Y. | Akinci N.

Article | 2011 | Journal of Quantitative Spectroscopy and Radiative Transfer112 ( 18 ) , pp.2814 - 2825

We present here in terms of a dyadic Green's function (DGF) a general description of optical phenomena in photonic crystal (PC) structures, described particularly by frequency-dependent components, assuming that PC structures are decomposed into their relatively simple constituent parts via conductivity tensors. We demonstrate this approach by explicitly calculating the DGFs for electromagnetic waves propagating in the one- and two-dimensional dispersive PCs consisting of a periodic array of identical metallic quantum wells and a periodic square array of identical metallic quantum wires, each embedded in a three-dimensional dispersi . . .ve medium. By means of the explicit analytic dispersion relations, which result from the frequency poles of the corresponding DGFs, we also calculate the band structures of these dispersive PCs by simple numerical means. Our analysis shows that the band structures calculated from our DGF approach conform well with those calculated from the traditional computational methods. © 2011 Elsevier Ltd Daha fazlası Daha az

Şahin Z. | Kopaç M. | Aydin N.O.

Article | 2011 | Isi Bilimi Ve Teknigi Dergisi/ Journal of Thermal Science and Technology31 ( 1 ) , pp.85 - 107

In this study the energy and exergy analysis have been applied to the power plant in the Iron and Steel Works Co. This plant consist of two parts, which could be described as old and new sections. These components work together as an integrated power plant. In this work, the irreversibility rates and energy losses of each units have been determined separately by energy and exergy analysis. Also, units have been compared by irreversibility rates and some considerable suggestions have been made to improve efficiency. It is suggested to remove three pressure reduction units (PDD1, PDD2, PDD3), have a total irreversibility rate of 6054 . . .kW, from the existing plant and replaced by a turbo-generator (TG4). Calculated results showed that the increments of overall thermal ( or first law) efficiency and overall exergy (or second law) efficiency of suggested plant were 2.27 and 2.21 %, respectively. ©2008 TIBTD Printed in Turkey Daha fazlası Daha az

To analyze the effect of possible risk factors, including breastfeeding, on the development of childhood-onset psoriasis, a multicenter case-control study with prospective collection of data was performed. Using a standard questionnaire, personal and specific variables including family history of psoriasis, maternal and environmental tobacco smoke exposure, body mass index (BMI), exclusive and partial breastfeeding for at least 3 and 12 months, cow's milk intake before 1 year, birth delivery method, and stressful life events were collected during 2009 from 537 patients with psoriasis and 511 controls younger than 18. Overall, patien . . .ts more frequently reported exposure to environmental tobacco smoke at home and stressful life events in the year preceding the diagnosis than controls. The odds ratios (OR) for smoking and stressful life events were 2.90 (95% confidence interval [CI] = 2.27-3.78) and 2.94 (95% CI = 2.28-3.79), respectively. In addition, children with psoriasis were more likely to have a higher BMI (>26) than controls (OR = 2.52; 95% CI = 1.42-4.49). High BMI, environmental tobacco smoke exposure at home, and stressful life events may influence the development of pediatric psoriasis. © 2011 Wiley Periodicals, Inc Daha fazlası Daha az

Aim: Several models of experimental ulcerative colitis have been previously reported. To date, only one model of Crohn's colitis that was induced by trinitrobenzene sulfonic acid has been described. Materials and Methods: Twenty-one male albino rats were divided into three groups: group I: sham control group (n = 7), group II: acetic acid group (n = 7), group III: NaOH group (n = 7). On the day of induction, all rats were lightly anesthetized with intramuscular ketamine (8 mg/kg). A 6F plastic catheter was inserted rectally until the tip was 5 cm proximal to the anus. Then, 2 ml of 0.9% saline, 2 ml of 4% acetic acid, and 2 ml of 6. . . .25% NaOH was administered to groups I, II, and III, respectively. All rats were sacrificed 5 days after colitis induction. The distal colon segment was assessed macroscopically and microscopically. In addition, malondialdehyde (MDA) and nitric oxide (NO) levels of the colonic tissue and changes in body weight were measured. Results: Macroscopic and microscopic examinations of colonic tissue samples showed morphological similarities to human Crohn's disease (CD). The MDA and NO levels of the colonic tissues were significantly higher in the NaOH group compared to the acetic acid and sham control groups (P = 0.001). Conclusion: NaOH may be used to induce Crohn's colitis as an experimental model. © 2011 Springer Science+Business Media, LLC Daha fazlası Daha az
