Validation of an assessment centre process for the selection of school leaders in Chile     

Paulo Volante  Sergio Valenzuela  Alejandro Díaz  Magdalena Fernández  Antonio Mladinic 《School Leadership & Management》2019,39(1):26-47

This study seeks to develop and validate an Assessment Centre (AC) tool for the evaluation and selection of school leaders, focusing on the identification of competencies that influence teaching and learning outcomes. International research supports the creation of Assessment Centres to select candidates for these roles, due to their superior predictive capacity over traditional methods. In this research, a model composed of four face-to-face instruments (an interview to assess competencies, a human resources exercise, a class observation exercise, and a strategic analysis exercise) was designed and validated which simulated the key tasks of a school principal. To establish the desired performance outcomes, three competencies and 15 indicators were selected, based on international and local standards. The analysis of performance results was obtained from a sample of 164 participants made up of teachers, school leaders and principals. The results suggest positive evidence for construct validity, concurrent criteria validity, and reliability between evaluators. Moreover, the data obtained from a sub-sample of principals, with three or more years of experience in their role, allowed for the association of their AC scores with the results of their school organisations, as measured by the National System for the Measurement of Educational Quality in the years 2013 and 2016.  相似文献   

Tangible User Interfaces and Contrasting Cases as a Preparation for Future Learning     

Bertrand Schneider  Paulo Blikstein 《Journal of Science Education and Technology》2018,27(4):369-384

In this paper, we describe an experiment that compared the use of a Tangible User Interface (physical objects augmented with digital information) and a set of Contrasting Cases as a preparation for future learning. We carried out an experiment (N?=?40) with a 2?×?2 design: the first factor compared traditional instruction (“Tell & Practice”) with a constructivist activity designed using the Preparation for Future Learning framework (PFL). The second factor contrasted state-of-the-art PFL learning activity (i.e., students studying Contrasting Cases) with an interactive tabletop featuring digitally enhanced manipulatives. In agreement with prior work, we found that dyads of students who followed the PFL activity achieved significantly higher learning gains compared to their peers who followed a traditional “Tell & Practice” instruction (large effect size). A similar effect was found in favor of the interactive tabletop compared to the Contrasting Cases (small-to-moderate effect size). We discuss implications for designing socio-constructivist activities using new computer interfaces.  相似文献   

Using the Bifocal Modeling Framework to Resolve “Discrepant Events” Between Physical Experiments and Virtual Models in Biology     

Paulo Blikstein  Tamar Fuhrmann  Shima Salehi 《Journal of Science Education and Technology》2016,25(4):513-526

In this paper, we investigate an approach to supporting students’ learning in science through a combination of physical experimentation and virtual modeling. We present a study that utilizes a scientific inquiry framework, which we call “bifocal modeling,” to link student-designed experiments and computer models in real time. In this study, a group of high school students designed computer models of bacterial growth with reference to a simultaneous physical experiment they were conducting, and were able to validate the correctness of their model against the results of their experiment. Our findings suggest that as the students compared their virtual models with physical experiments, they encountered “discrepant events” that contradicted their existing conceptions and elicited a state of cognitive disequilibrium. This experience of conflict encouraged students to further examine their ideas and to seek more accurate explanations of the observed natural phenomena, improving the design of their computer models.  相似文献

Career Dilemmas in Career Counseling Groups: Theoretical and Practical Issues     

Paulo Jorge Santos 《Journal of Career Development》2004,31(1):31-44

A career dilemma is a hypothetical or real situation in which a character is confronted with several career options each of which has advantages and disadvantages. The main purpose of presenting and discussing a dilemma in career counseling groups is to confront several appraisals of the situation in order to promote more complex thinking about career choices. Another important aim of this technique is to enhance interaction between group members and to analyze similar career dilemmas that the group participants have experienced in the past. The use of the discussion of career dilemmas is described, especially the role of the career counselor, and some suggestions for future research are presented.  相似文献   

Cooperation in innovation activities: The importance of partners   总被引：1，自引：0，他引：1  

Pedro de Faria  Francisco Lima 《Research Policy》2010,39(8):1082-1092

This paper analyses the importance of cooperation partners for the development of innovation activities. We contribute to the literature on cooperation in innovation activities that seeks to identify the characteristics differentiating cooperative from non-cooperative firms by proposing a different approach to this problem. We distinguish firms according to their evaluation of cooperation partners in the development of innovation activities. We apply a probit selection model to account for the firm's decision to cooperate (or not). The data we use come from the Portuguese Third Community Innovation Survey. Our estimation results show that firms from high-technological industries, with higher levels of absorptive capacity and of innovation investment, who give importance to incoming spillovers management, and who cooperate with firms from the same group or with suppliers, place greater value on cooperation partners in the innovation process. Additionally, we also find that the factors influencing the importance attributed to cooperation activities are different from the ones behind the decision to cooperate.  相似文献   

Protective effects of photobiomodulation against resistance exercise-induced muscle damage and inflammation in rats     

Helenita Antonia de Oliveira  Ednei Luiz Antonio  Flávio André Silva  Paulo de Tarso Camillo de Carvalho  Regiane Feliciano  Amanda Yoshizaki 《Journal of sports sciences》2018,36(20):2349-2357

We investigated whether low-level laser therapy (LLLT) prior to or post resistance exercise could attenuate muscle damage and inflammation. Female Wistar rats were assigned to non-LLLT or LLLT groups. An 830-nm DMC Laser Photon III was used to irradiate their hind legs with 2J, 4J, and 8J doses. Irradiations were performed prior to or post (4J) resistance exercise bouts. Resistance exercise consisted of four maximum load climbs. The load work during a resistance exercise bout was similar between Control (non-LLLT, 225 ± 10 g), 2J (215 ± 8 g), 4J (210 ± 9 g), and 8J (226 ± 9 g) groups. Prior LLLT did not induce climbing performance improvement, but exposure to 4J irradiation resulted in lower blood lactate levels post-exercise. The 4J dose decreased creatine kinase and lactic dehydrogenase levels post-exercise regardless of the time of application. Moreover, 4-J irradiation exposure significantly attenuated tumor necrosis factor alpha, interleukin-6, interleukin-1β, cytokine-induced neutrophil chemoattractant-1, and monocyte chemoattractant protein-1. There was minor macrophage muscle infiltration in 4J-exposed rats. These data indicate that LLLT prior to or post resistance exercise can reduce muscle damage and inflammation, resulting in muscle recovery improvement. We attempted to determine an ideal LLLT dose for suitable results, wherein 4J irradiation exposure showed a significant protective role.  相似文献   

Acute kinematics changes in marathon runners using different footwear     

Tania Socorro Amorim Soares  Federico Pizzuto  Rui Manuel Garganta  João Paulo Vila-Boas  Mario Casimiro da Anunciação Paiva 《Journal of sports sciences》2018,36(7):766-770

The effects of running with or without shoes on injury prevention have been extensively studied, and several investigations have assessed biomechanical differences between them. However, findings are not consensual and further insights on biomechanical load associated with differently shod or barefoot conditions may be needed. This study aimed to observe if habitually shod marathon runners show acute alterations when running barefoot or with minimalist shoes, and to determine whether the running kinematical adaptations of wearing minimalist shoes were similar to barefoot running. Twelve male marathon runners ran on the treadmill at their average marathon pace in different footwear conditions: habitual running shoes, minimalist shoes, and barefoot. High-resolution infrared cameras and visual 3D software were used to assess kinematic data. The following parameters were studied: foot strike angle, cycle time, stance time, normalized stride length, hip, knee, and ankle angular position at initial contact, and their respective range-of-motion (ROM) during stance phase. Contrary to the expectations, it was found that highly trained habitually shod elite marathon runners changed their lower limb kinematic pattern both when running barefoot or wearing minimalist shoes. Minimalist shoes showed a trend towards intermediate biomechanical effects between running with and without shoes.  相似文献
