Effectiveness of classroom management strategies in large groups 35-45 students in the national institute Guillermo Cano Balladares

This article focuses on present aspects about the effectiveness of classroom management strategies in large groups’ 35-45 students in a high school level. In this paper we explain some conceptions related to classroom management, the prescriptive strategies to be a good classroom manager and different teacher management styles. Afterwards, it describes our methodological design, the analysis, and discussions of the results gotten in this study. Finally, we propose authentic strategies and suggestions to be the best classroom manager and how to deal with large groups students

Effectiveness of english classroom management strategies with overcrowded group in 9th grade students, at Guillermo Cano Institute during the second semester 2015

Teaching and learning English is essential in the world we live in, for this reason the need to teach and learn English language using Effectives strategies to work with overcrowded group to help the students to develop communication. This research study is about; Effectiveness of English classroom management strategies with overcrowded group with 9th grade students, at Guillermo Cano institute during the second semester 2015 The main objective of the study was to analyze the effectiveness of classroom management strategies in Teaching-learning English with overcrowded group. The total population of the research consists of 376 students and 10 teachers. Of this population a sample of 1 teacher and 37 students of 9th grades were selected

High PEEP with recruitment maneuvers versus Low PEEP During General Anesthesia for Surgery -a Bayesian individual patient data meta-analysis of three randomized clinical trials

Background: The influence of high positive end-expiratory pressure (PEEP) with recruitment maneuvers on the occurrence of postoperative pulmonary complications after surgery is still not definitively established. Bayesian analysis can help to gain further insights from the available data and provide a probabilistic framework that is easier to interpret. Our objective was to estimate the posterior probability that the use of high PEEP with recruitment maneuvers is associated with reduced postoperative pulmonary complications in patients with intermediate-to-high risk under neutral, pessimistic, and optimistic expectations regarding the treatment effect. Methods: Multilevel Bayesian logistic regression analysis on individual patient data from three randomized clinical trials carried out on surgical patients at Intermediate-to-High Risk for postoperative pulmonary complications. The main outcome was the occurrence of postoperative pulmonary complications in the early postoperative period. We studied the effect of high PEEP with recruitment maneuvers versus Low PEEP Ventilation. Priors were chosen to reflect neutral, pessimistic, and optimistic expectations of the treatment effect. Results: Using a neutral, pessimistic, or optimistic prior, the posterior mean odds ratio (OR) for High PEEP with recruitment maneuvers compared to Low PEEP was 0.85 (95% Credible Interval [CrI] 0.71 to 1.02), 0.87 (0.72 to 1.04), and 0.86 (0.71 to 1.02), respectively. Regardless of prior beliefs, the posterior probability of experiencing a beneficial effect exceeded 90%. Subgroup analysis indicated a more pronounced effect in patients who underwent laparoscopy (OR: 0.67 [0.50 to 0.87]) and those at high risk for PPCs (OR: 0.80 [0.53 to 1.13]). Sensitivity analysis, considering severe postoperative pulmonary complications only or applying a different heterogeneity prior, yielded consistent results. Conclusion: High PEEP with recruitment maneuvers demonstrated a moderate reduction in the probability of PPC occurrence, with a high posterior probability of benefit observed consistently across various prior beliefs, particularly among patients who underwent laparoscopy
