Science Teachers’ Reflective Practices: Perspectives and Attitudes

ABSTRACT Studies investigating reflective practices among teachers have focused on reflective practice use in teaching and teacher’s professional development. The attitudes of teachers toward reflective practices have been neglected, but the attitudes of science teachers toward reflective practices are key to their effective use in classroom settings. This study aimed to understand the attitude of science teachers toward these practices and how they implement professional reflective practices as well as any relationship between reflective practices and attitudes. A sample of 650 science teachers, 321 males and 329 females completed the questionnaire. Results revealed that science teachers practiced all reflective activities at high levels. Additionally, their attitudes toward reflective practices were moderately positive. Pearson correlation coefficients for the relationship between the reflective practices and attitudes of science teachers were statistically significant at p d” 0.01. Hence, science teachers who had positive attitudes toward reflective practices were likely to demonstrate more reflective teaching in their educational careers.

Minimum Intensity

Purpose The minimum masking level (MML) is the minimum intensity of a stimulus required to just totally mask the tinnitus. Treatments aimed at reducing the tinnitus itself should attempt to measure the magnitude of the tinnitus. The objective of this study was to evaluate the reliability of the MML. Method Sample consisted of 59 tinnitus patients who reported stable tinnitus. We obtained MML measures on two visits, separated by about 2–3 weeks. We used two noise types: speech-shaped noise and high-frequency emphasis noise. We also investigated the relationship between the MML and tinnitus loudness estimates and the Tinnitus Handicap Questionnaire (THQ). Results There were differences across the different noise types. The within-session standard deviation averaged across subjects varied between 1.3 and 1.8 dB. Across the two sessions, the Pearson correlation coefficients, range was r = .84. There was a weak relationship between the dB SL MML and loudness, and between the MML and the THQ. A moderate correlation ( r = .44) was found between the THQ and loudness estimates. Conclusions We conclude that the dB SL MML can be a reliable estimate of tinnitus magnitude, with expected standard deviations in trained subjects of about 1.5 dB. It appears that the dB SL MML and loudness estimates are not closely related.

The Relationship

The United States Army recently implemented the Army Combat Fitness Test (ACFT) which was designed to more accurately measure functional-combat fitness constructs. The ACFT replaced the former Army Physical Fitness Test (APFT). The three advent APFT consisted of: two-minute push-ups (PU), two-minute sit-ups (SU), and a timed two-mile run (RUN). The ACFT consists of six events; 3 Rep Max Deadlift (MDL), Standing Power Throw (SPT), Hand Release Push-up (HRP), Sprint-Drag-Carry (SDC), Hanging Leg Tuck (LTK), and a timed two-mile run (2MR). This study investigated the relationship between Soldier height and body mass kg on ACFT scores of 655 male U.S. Army National Guard Soldiers in a Field Artillery Brigade. For the purpose of the investigation body mass index (BMI) was calculated as the metric representing the Soldier(s) height and weight. The mean and standard deviation (sd) were calculated for the ACFT event and total scores. Pearson correlation coefficients (PCCs or r) were calculated between BMI and ACFT event and total scores. Likewise, PCCs were calculated between the ACFT event and total scores. The ACFT mean(sd) scores were as follows: MDL=92.2(31.8) (3 maximum repetitions), SPT=9.5(2.2) (meters), HRP=24.6(13.1) (repetitions), SDC=119.8(21.7) (seconds), LTK=6.2(5.4) (repetitions), 2MR=1095.0(233.7) (seconds), ACFT total score=442.3(54.4) (points). Significant positive correlations were found between the ACFT total score: MDL (r=0.70), SPT (r=0.50), HRP (r=0.74), and LTK (r=0.76) events. Conversely, significant negative correlations were identified between ACFT total score: SDC (r=-0.68) and 2MR (r=-0.53) events. Within the parameters of this study, Soldier BMI demonstrated no to weak association with individual ACFT event or ACFT total scores. Further, the range of PCCs between the ACFT event scores were no to moderately high. Military leaders may consider the results provided as combat and fitness tests continue to evolve.

The Relationship

While there is a significant amount of research and literature to explain the role of reflective practice in teaching, there is little research that reported the extent of such practice on classroom instructions and its spill effects on student learning outcomes. For this reason, this paper looks at the magnitude of reflective practice in shaping classroom instructions and how it facilitates for better student performance within the context of teachers’ professional development (PD) programs. Hence, the focus of the paper is two-fold: examining teachers’ PD programs that promoted reflective practice; and the relationship between reflective practice and student performance. The discussion on teachers’ reflective practice is timely. In particular, with the growing educational research and increasing body of evidence that pointed towards PD as having a significant influence on student achievement (Achinstein & Athanases, 2006; Fullan, 1990; Little, 2001). In addition, most PD efforts focused on teacher collaboration as a strategy for teaching improvement and eventually better academic performance of the students (Achinstein & Athanases, 2006). Many educators (Fendler, 2003; Loughran, 2002; Schon, 1983; Walkington, 2005) viewed reflective practice as situated at the heart of PD programs that sought teachers to examine their practice for improvement. This paper assists policy makers and education reformists in re-examining their PD efforts in targeting for variables that matter.

This study explores the perceptions of EFL instructors about their reflective practice and its effect on their professional development in a Saudi Arabian university. This study adopts an explanatory sequential mixed-methods approach to collect quantitative and qualitative data. Two study instruments were used; a survey questionnaire with a study sample of 100 male and female participants and semi-structured interviews with a study sample of seven female instructors. The findings show that some instructors in general have a positive perception of reflective practices and they utilize a diversity of reflective tools. Female instructors show a greater degree of involvement in a reflective practice than male instructors in three of the four examined dimensions (cognitive and meta-cognitive, moral and learner and reflective teaching in general). However, no significant difference is reported between males’ and females’ perceptions in terms of the fourth dimension (practical). Based on the findings, recommendations have been made to encourage reflective practices in the Saudi EFL context.

This article examines one of the key competencies of the 21st century known as cultural intelligence (CQ). This study investigates the relationship between CQ, organizational culture, and the effectiveness of staff in the industry, mine, and trade organizations of Semnan province in Iran. Using correlational analysis, the statistical population includes a total of 103 people from 141 employees based on personnel department documents. Three questionnaires were used to measure the variables and descriptive and deductive statistics were applied to evaluate and analyze the data. The Pearson correlation coefficient and multivariate regression were used in deductive statistics to obtain the results. The findings show there is a significant relationship between CQ, organizational culture, and effectiveness. Among four cultural intelligence factors, only the knowledge of CQ can predict the effectiveness. The calculated correlation coefficient indicates that the creativity factors and communication pattern have the highest correlation coefficients.

AbstractAnimal by-product meals have large variability in crude protein (CP) content and digestibility. In vivo digestibility procedures are precise but laborious, and in vitro methods could be an alternative to evaluate and classify these ingredients. The present study reports prediction equations to estimate the CP digestibility of meat and bone meal (MBM) and poultry by-product meal (PM) using the protein solubility in pepsin method (PSP). Total tract CP digestibility of eight MBM and eight PM samples was determined in dogs by the substitution method. A basal diet was formulated for dog maintenance, and sixteen diets were produced by mixing 70 % of the basal diet and 30 % of each tested meal. Six dogs per diet were used to determine ingredient digestibility. In addition, PSP of the MBM and PM samples was determined using three pepsin concentrations: 0·02, 0·002 and 0·0002 %. The CP content of MBM and PM ranged from 39 to 46 % and 57 to 69 %, respectively, and their mean CP digestibility by dogs was 76 (2·4) and 85 (2·6) %, respectively. The pepsin concentration with higher Pearson correlation coefficients with the in vivo results were 0·0002 % for MBM (r 0·380; P = 0·008) and 0·02 % for PM (r 0·482; P = 0·005). The relationship between the in vivo and in vitro results was better explained by the following equations: CP digestibility of MBM = 61·7 + 0·2644 × PSP at 0·0002 % (P = 0·008; R2 0·126); and CP digestibility of PM = 54·1 + 0·3833 × PSP at 0·02 % (P = 0·005; R2 0·216). Although significant, the coefficients of determination were low, indicating that the models were weak and need to be used with caution.

Abstract Background: Posttraumatic Stress Disorder (PTSD) is one of the most prevalent psychopathologies experienced by victims following natural disasters. The severity of traumatic experience may be a critical risk factor for the development of PTSD. Nevertheless, other factors may also lead to PTSD. We propose that fear and self-disclosure could be two important factors. Previous studies have examined their unique roles in PTSD, but their combined role in PTSD has been rarely assessed. To fill this gap, the aim of this study was to examine the relationship between severity of traumatic exposure, fear, self-disclosure, and PTSD among victims following flood disaster. Methods: one hundred ninety-nine participants completed self-report questionnaires. Descriptive statistics were obtained using SPSS 17.0 and Pearson correlation coefficients were calculated to obtain correlations between major variables. Results: results indicated that severity of traumatic exposure not only had a direct effect on PTSD, but also it had an indirect effect on PTSD via activating victims’ fear. Moreover, self-disclosure played a buffering role between fear and PTSD. However, the role of fear in PTSD may decrease with increases in levels of self-disclosure. Conclusions: Traumatic exposure had positive predictive effects for PTSD and fear. Self-disclosure had negative predictive effects for PTSD. Fear played a mediating role between severity of traumatic exposure and PTSD, self-disclosure played a moderating role in the relationship between fear and PTSD. Psychological interventions should focus on the regulation of fear and improvement of self-disclosure following traumatic exposure.

The Relationship

There have been a limited number studies that examined the relationship between professional development (PD) and self-efficacy with technology tool use, specifically concerning high school science teachers. The main goal of this quantitative study was to identify any specific correlations between science teacher self-efficacy and the professional development science teachers received for those specific classroom technologies. Participants were comprised of a randomized sample set of high school science teachers throughout 46 different US States.The data was collected by using an online survey via the Qualtrics survey platform. The survey was sent to 3000 science instructors and 104 in total completed it. The results suggest that science teachers’ efficacy was high with course management systems and student wireless or digital devices, but not for social networking/media. There was no significant connection between technological self-efficacy and PD for related technology tools. However, it is possible that science teachers are already highly efficacious in terms of technology, and observational studies are recommended to see when and how teachers actually use technology in their classrooms.

Abstract Aims Selection into UK medical school involves a combination of three measures: prior academic attainment, selection tests (e.g. the University Clinical Aptitude Test (UCAT), Biomedical Admissions Test (BMAT), or Graduate Medical School Admissions Test (GAMSAT)) followed by interview. We investigated the predictive power of current UK medical selection tests and measures of prior attainment on success in the Membership of the Royal College of Surgeons (MRCS) examination. Methods The UKMED database was used to analyse A-Levels and medical school selection data for all UK graduates who attempted the MRCS Part A written examination (n = 9729) and Part B clinical examination (n = 4644) between 2007 and 2017. Univariate analysis and Pearson correlation coefficients examined the relationship between selection scores and first attempt MRCS success. Results Successful MRCS Part A candidates scored higher in A-Levels, UCAT, BMAT and GAMSAT examinations (p < 0.05) than their unsuccessful peers, but no differences were observed for MRCS Part B. Statistically significant positive correlation was found between MRCS Part A, BMAT (r = 0.32, p < 0.001) and GAMSAT scores (r = 0.35, p = <0.001). While a weaker statistically significant correlation was found between Part A, A-Level (r = 0.14, p < 0.001) and UCAT scores (r = 0.25, p < 0.001). Conclusions This, the first study to investigate the relationship between all UK medical school selection tests and success in a postgraduate examination found statistically significant correlations between selection test scores and performance on Part A of the MRCS. The strength of correlations found in this study are similar to those of other validated selection tests used in the United States.

Abstract Introduction This study aims to assess the relationship between LMs, PLMD and limb related arousals during sleep and subjective sleepiness in a group of professional athletes (National Rugby League (NRL) players). Methods 25 type II HSAT polysomnographic (PSG) studies were performed on 23 male individuals (2 repeated studies). 2 x Piezo limb EMG sensors were applied to each HSAT. PSG data analysed as per AASM Manual for the Scoring of Sleep and Associated events. Epworth Sleepiness Scale (ESS) collected for each participant obtaining subjective daytime sleepiness. PSG data was checked for normality using the Shapiro-Wilk normality test. Parametric data was then subsequently analysed using Pearson correlation coefficients, whereas non-parametric data was analysed with the Spearman correlation coefficient. A line of best fit was implemented using Deming’s linear regression model to report r2. Results The most significant relationships were noted between daytime sleepiness and the frequency of limb-related arousals (Pearson’s r 0.273) and the relationship between PLM arousals and ESS (p-0.082). No significant relationships were noted between LMs, PLMs, limb related arousals and daytime sleepiness were found. No results were found to be statistically significant. Conclusions This PSG data demonstrates a mildly positive correlation with all limb movement parameters measured against the athletes’ self-reported sleepiness. This may therefore be of significance with their performance and recovery. Further research is recommended to verify these relationships.
