Effects of cooperative learning on perceived competence,motivation, social goals,effort and boredom in prospective Primary Education teachers / Efectos del aprendizaje cooperativo sobre la competencia percibida,la motivación,las relaciones sociales,el esfuerzo y el aburrimiento de futuros docentes de Educación Primaria

Abstract

The main goal of this study was to analyze the effects of an intervention programme based on cooperative learning on several motivational variables in prospective teachers. 264 students of Primary Education Teacher Training participated. Prior to the intervention, a theoretical model was designed to explain the relations among the different variables. The intervention programme was applied to the experimental group during a 12-week period, while the control group experienced a traditional instructional approach. A questionnaire was designed using different validated subscales (PMCSQ-2, BPNS, PLOC, SGS-PE, PES) to gather data. The predictive theoretical model was tested using a structural equation analysis with the data obtained, which showed that the predictive model was correct, and significant improvements were seen in the experimental group only in terms of levels of perceived competence, self-determined motivation, effort, responsibility and relationships, and a significant decrease was seen in boredom. With regard to gender, women showed significantly different results in Competence and Boredom. Cooperative Learning has been proven to be a positive instructional model in Teacher Education.     

Creating and Implementing a Faculty Interest Group for Historically Underrepresented Faculty

This article describes the creation and implementation of a faculty interest group for historically underrepresented faculty at a large, urban community college in the Northeast. Faculty interest groups provide opportunities for faculty across disciplines to meet to explore common interests and share concerns and best practices. The faculty interest group described in this article was designed to explore and address the challenges faced by historically underrepresented faculty and facilitate the process of attaining reappointment, promotion, and tenure. Nationwide, nearly half of community college students come from populations that are also historically underrepresented, and community colleges are challenged to recruit and retain faculty that mirror the student body. Research demonstrates that historically underrepresented faculty members enrich the overall education of all students, and yet a significant number of those faculty members describe their college campuses as unwelcoming. Factors that make campuses unwelcoming for these faculty include, but are not limited to, the following: isolation and marginalization; salary disparities; microaggressions based on race, gender, and sexual identity; heightened visibility; and additional role demands. Community college administrators ought to be concerned with historically underrepresented faculty members’ satisfaction and persistence on campus because these faculty members are vital members of the academy. Faculty interest groups for historically underrepresented faculty may provide the support and professional development opportunities that will ensure their retention and success in academia.     

Exploring the relationship among learning patterns,personality traits,and academic performance in freshmen

Providing information about how 1st-year students learn may help colleges plan actions aimed at increasing students' persistence in higher education programs. This research aims to assess 1st-year students' academic performance, using a path analysis to establish inter-correlations among students' personality traits, learning patterns, high school achievement, and objectively measured outcomes. Participants included 509 freshmen from different academic disciplines. Results show a causality relations model in which Conscientiousness positively influences Sequential and Precise learning patterns as well as academic performance. The path model also confirms Extraversion as a negative antecedent of the Technical learning pattern. It is argued that knowing students is a primary step to putting them in a position to become an active part of the learning process.     

Science Letters：Visual odometry for road vehicles —— feasibility analysis

Estimating the global position of a road vehicle without using GPS is a challenge that many scientists look forward to solving in the near future. Normally, inertial and odometry sensors are used to complement GPS measures in an attempt to provide a means for maintaining vehicle odometry during GPS outage. Nonetheless, recent experiments have demonstrated that computer vision can also be used as a valuable source to provide what can be denoted as visual odometry. For this purpose, vehicle motion can be estimated using a non-linear, photogrametric approach based on RAndom SAmple Consensus (RANSAC). The results prove that the detection and selection of relevant feature points is a crucial factor in the global performance of the visual odometry algorithm. The key issues for further improvement are discussed in this letter.     

Disinfection by-products effect on swimmers oxidative stress and respiratory damage

Disinfection by-products (DBPs) are generated through the reaction of chlorine with organic and inorganic matter in indoor swimming pools. Different DBPs are present in indoor swimming pools. This study evaluated the effects of different chlorinated formations in oxidative stress and lung damage in 20 swimmers after 40?min of aerobic swimming in 3 indoor pools with different characteristics. Biological samples were collected to measure lung damage (serum-surfactant-associated proteins A and B), oxidative stress parameters (plasma protein carbonylation and malondialdehyde, and whole-blood glutathione oxidation), and swimming exertion values (blood lactate) before and after exercise. Free chlorine and combined chlorine in water, and chlorine in air samples were determined in all the swimming pools. Chlorination as disinfection treatment led to the formation of chloramines in water samples, mainly mono- and dichloramine. However, free chlorine was the predominate species in ultraviolet-treated swimming pool. Levels of total chlorine increased as a function of the swimming activity in chlorinated swimming pools. The lower quality of the installation resulted in a higher content of total chlorine, especially in air samples, and therefore a higher exposure of the swimmer to DBPs. However, the concentration level of chlorinated DBPs did not result in significant variation in serum-surfactant-associated proteins A and oxidative stress parameters in swimmers. In conclusion, the quality of the installation affected the DBPs concentration; however, it did not lead to lung epithelial damage and oxidative stress parameters in swimmers.     

The asymmetry of pectoralis muscles is greater in male prepubertal than in professional tennis players

It is generally accepted that preadolescents have a limited capacity to develop muscle hypertrophy in response to exercise compared with older populations; however, studies are scarce and conflicting. The main aim of the present study was to assess if playing tennis is associated with the hypertrophy of dominant pectoralis muscles (PM) in professional (PRO) and in prepubescent tennis players (PRE). A secondary aim was to assess if the degree of asymmetry of PM is greater in PRO than PRE. The volume of PM of both sides was determined using magnetic resonance imaging in 8 male PRO (21.9 years), 6 male PRE (11 years, Tanner 1–2) and 12 male non-active controls (6 adults: 23.5 years; and 6 prepubescents: 10.7 years, Tanner 1–2). PRO and PRE had 15 and 30% greater volume, respectively, in the dominant than in the contralateral PM (P?P?=?.34 in adults and 5%, P?=?.17 in children). The degree of side-to-side asymmetry in PM volume was greater in PRE than in PRO (P?相似文献   

Islamic religious education and the plan against violent radicalization in Spain

ABSTRACT

This article analyses the importance of Islamic religious education in public schools in Spain as an instrument in the prevention and fight against violent radicalisation. In this article, we examine the legal status of Islamic religious education and the latest regulations on Islamic religious education that emphasise the fight against Islamist terrorism. We also study the regulation of teachers of Islamic religious education and their role in the counter-narrative required to deter the message of Islamist terrorists and prevent violent radicalisation.     

Inland Water Quality Assessment - A Joint European Masters Programme

At present, there is a European shortage of personnel qualified to adequately address the comprehensive scientific and regulatory requirements of the Water Framework Directive (WFD). The joint Masters programme described in this paper will provide students with the requisite expert knowledge and skills to progress the implementation of the WFD. Its development was financially supported by the European Commission because of its specific goal of producing qualified personnel in relation to the implementation of the WFD. Since its proposed structure acknowledges the educational intent of the Bologna Accord, it thereby provides a useful template for structuring a Masters degree-level programme in accordance with Bologna principles.
