Belief Change Before and After the Teaching Practicum Among Chinese Pre-Service ELT Teachers

This article aims to study the dynamic change of teachers’ beliefs among pre-service teachers. A longitudinal design was adopted to investigate English language teaching (ELT) pre-service teachers’ belief change after a 3-month teaching practicum by administering pretest and posttest questionnaires, semistructured interviews, and reflective journals. Repeated measures and paired sample t-test analyses showed significant differences across different aspects of beliefs in all the participants, but belief changes were significant after the practicum only within the experimental group, particularly in the aspects of student management, teaching evaluation, and student learning. In contrast, belief changes were not significant within the control group. Further inductive content analyses of semistructured interviews and reflective journals from the experimental group confirmed these changes and conclusively revealed some potential factors contributing to the changes. The results shed light on how pre-service teachers evolve in their career development and help educators adjust appropriate education policies to improve the quality of English teacher education, particularly in the Chinese context.

Experimental Group

Background. Abdominal and lumbo-pelvic stability alterations may be the origin of lower limb injuries, such as adductor pathology in soccer players. Imbalance can be caused by both intrinsic and extrinsic factors. Methods: In this randomized controlled trial over 8 weeks, 25 female footballers were randomly allocated to an experimental group (isometric abdominal training and gluteus medius-specific training) or a control group (isometric abdominal training). Evaluations were performed at baseline, at the end of the intervention and after a 4-week follow-up period. The exercise protocol in common for both groups included three exercises: Plank, Lateral plank and Bird dog. Specific exercises for the gluteus medius were: Pelvic drop and Stabilization of the gluteus medius in knee valgus. Outcome measures were lumbar-pelvic stability and adductor strength. Results: After the intervention, there was an increase in lumbo-pelvic stability in both groups, being greater in the control group than in the experimental group (mean differences [MD]: 4.84 vs. MD: 9.58; p < 0.01) with differences in the analysis of repeated measures (p < 0.001), but not in group interaction (p = 0.26). Changes were found in adductor strength in the experimental group (MD: −2.48; p < 0.001 in the left adductor; MD: −1.48; p < 0.01 in right adductor) and control group (MD: −1.68; p < 0.001 in the left adductor; MD: −2.05; p < 0.001 in the right adductor) after the intervention, with differences in the analysis of repeated measures in left (p < 0.001) and right (p < 0.001) adductor strength. Conclusions: An abdominal and gluteal training protocol shows no advantage over a protocol of abdominal training alone for lumbo-pelvic stability and adductor strength, while improvements in both variables are maintained at four weeks follow-up.

Maintaining stable physiological responses may be important for the growth and development of preterm infants. The purpose of our study was to evaluate the effects of olfactory stimulation with maternal breast milk on the occurrence of abnormal physiological responses in preterm infants. With a non-equivalent control group pretest-posttest design, 13 preterm infants in the experimental group and 18 preterm infants in the control group completed the intervention. The intervention was implemented three times a day for 5 days in a row with 2 hours of administration per intervention. The frequency of abnormal physiological responses was assessed over 6 days (one day before intervention administration and 5 days during intervention administration). With repeated-measures analysis of variance, the experimental group showed a significantly lower frequency of apnea than the control group ( p = .021). Olfactory stimulation with maternal breast milk may be an effective nursing intervention for reducing apnea episodes in preterm infants.

AbstractBackground & ObjectivesThe douche, one of the hydrotherapeutic treatment modality is commonly used by Naturopathy physicians as a treatment of choice in the management of several ailments. This study was done to assess the effect of full body neutral douche in the management of pain and systemic symptoms in adult females with primary dysmenorrhoea.Methods68 subjects of age 18-22 years with primary dysmenorrhoea were recruited for the study and were randomly divided into two groups: the experimental group (n = 34) and the control group (n = 34). The experimental group received whole body neutral douche, whereas the control group followed the routine as usual. Assessments for the pain, systemic symptoms and menstrual cramps were done by using McGill Pain Questionnaire, Verbal multidimensional scoring system and analog scale for severity of pain and menstrual cramps respectively at baseline, day 30 and day 60 of intervention. Two- way repeated measures of ANOVA was performed to understand the between group changes, adjusted for the respective baseline values and age.ResultData was analyzed with SPSS (Version 21.0) package. Neutral douche resulted in significant improvement in pain [F(2,66) = 114.564, p < 0.0005, partial ?2 = 0.771], severity of pain [F(2,66) = 70.418, p < 0.0005, partial ?2 = 0.681], cramps [F(2,66) = 75.986, p < 0.0005, partial ?2 = 0.697] and systemic symptoms [F(2,66) = 14.64, p < 0.0005, partial ?2 = 0.307] as compared to the control group.ConclusionFindings suggest that neutral douche can be used as a non-pharmacological intervention in the management of pain and systemic symptoms in primary dysmenorrhea.

This research examines the effect of educational games on self-concept levels of inclusive students enrolled in secondary schools. The research was conducted in two secondary schools in Golbasi district of Ankara, the capital of Turkey, in the spring semester of 2015 - 2016 academic year. The research employed semi-experimental design with pretest and posttest control group. Of a total of 24 students, 12 (4 girls, 8 boys) were included in the experimental group and the other 12 (6 girls, 6 boys) were included in the control group. Educational games program, an independent variable of the research, was applied for 11 weeks, 2 lessons per week. The program that did not include educational games was applied to the control group. Self-concept Scale (SCS) was used to collect data in the research. Independent group t test was used for data analysis, and for single-factor repeated measures, two-factor ANOVA test was used. The significance level was determined to be 0.05. At the end of this research, a significant difference was found in favor of the students in the experimental group in terms of physical competence, physical appearance, peer relationships and general self-concept dimensions of the self-concept scale. On the other hand, there was not any significant difference in favor of both groups in terms of the dimension of relations with parents of the scale.

SUMMARY Objective This single-blind controlled study evaluated the genotoxicity and efficacy of at-home bleaching in smokers and nonsmokers. Methods We selected 60 patients with central incisors A2 or darker: 30 smokers (experimental group) and 30 nonsmokers (control group). The bleaching was carried out with 10% carbamide peroxide for three hours a day for three weeks. The color was evaluated using a shade guide, Vita Bleachedguide 3D-Master, at baseline, during bleaching (first, second, and third weeks), and one week and one month after bleaching. Smears were obtained with a moistened wooden spatula from marginal gingiva. All the cytologic smears were stained with Giemsa solution. From each slide, 1000 cells were examined under 40× magnification and where micronuclei (MN) were located, they were examined under 100× magnification. The change in shade guide units at the different assessment periods and the frequency of MN were subjected to a two-way repeated measures analysis of variance and Tukey test (α=0.05). Results In both groups we detected a whitening of approximately 4 to 5 shade guide units, without color rebound after one month (p>0.05). The frequency of MN was significantly higher in the experimental group than in the control group, regardless of the bleaching treatment (p>0.001). Conclusion The efficacy of bleaching does not appear to be affected by the smoking habit. Additionally, at-home bleaching did not induce DNA damage to the gingival tissue during the bleaching period.

The purpose of this study was to evaluate the effect of replacing a component of the self-etch adhesive Adper Scotchbond SE (liquid A + liquid B) by 2% chlorhexidine (CHX) on bond strength to dentin after 1 day, 3 months or 6 months of water storage. Eight human teeth were sectioned to expose a flat dentin surface and were then randomly assigned to 2 groups. In the control group, the dentin surfaces were treated with the adhesive according to the manufacturer's instructions. In the experimental group, liquid A was replaced by 2% CHX. Next, a 6-mm-high resin composite block was incrementally built on the bonded surfaces. The restored teeth were then sectioned to produce stick-shaped specimens (cross-sectional area - 0.8 mm2). The microtensile bond strength (µTBS) was recorded, and the failure modes were assessed. Data were analyzed by two-way repeated measures ANOVA (α=0.05). Four additional teeth were processed in order to conduct a micromorphological analysis of the resin-dentin interface. The µTBS values did not significantly decrease after water storage in either the control or the experimental group, whose values did not differ significantly irrespective of storage time. The morphological aspect of the bonding interface appears not to have been affected by CHX. A higher incidence of cohesive failures within the adhesive and mixed failures (cohesive within adhesive and resin composite) was observed for both groups. It may be concluded that dentin pre-treatment with 2% CHX did not influence significantly the bonding performance of the evaluated adhesive.
