Exploring marine ecosystems with elementary school Portuguese children: inquiry-based project activities focused on ‘real-life’ contexts     

Elsa Guilherme  Diana Boaventura 《Education 3-13》2016,44(6):715-726

The purpose of the study was to investigate how young students engage in an inquiry-based project driven by real-life contexts. Elementary school children were engaged in a small inquiry project centred on marine biodiversity and species adaptations. All activities included the exploration of an out-of-school setting as a learning context. A total of 49 students and 2 teachers were involved in the activities. The research methods included observation, document analysis and content analysis of the answers to a questionnaire and an interview. The results revealed that most of the students acquired scientific knowledge related to biological diversity and adaptations to habitat. Moreover, students progressively demonstrate greater autonomy, argumentative ability and decision-making. One implication of the present study is that elementary science curriculum could be better managed with inquiry project-based activities that explore different types of resources and out-of-school settings.  相似文献

Analysis of a multifaceted interactive pedagogy program in an upper limb anatomy course: A time series study     

Alexandre Bellier  Noémie Kaladzé  Pierre-Yves Rabattu  Philippe C. Chaffanjon  Guillaume Cavalié 《Anatomical sciences education》2023,16(1):116-127

Many new methods have contributed to the learning of anatomy, including several interactive methods, increasing the effectiveness of educational programs. The effectiveness of an educational program involving several interactive learning methods such as problem-based learning and reciprocal peer teaching was researched in this study. A quasi-experimental before–after study on three consecutive groups of second-year students at the Grenoble School of Medicine was conducted. The lectures were replaced by an educational program based on the problem-based learning method and reciprocal peer teaching. The first session was dedicated to reading clinical cases illustrating the medical concept, so that the learning objectives for the second session could be set. Then, after viewing digital courses, the second session was dedicated to a synthetic presentation by the students themselves, followed by an interactive summary with the teacher. The analysis of 630 students showed a significant increase in the theory test results for those who took part in the intervention: 9.71 versus 9.19 (β = 0.57, P = 0.036). Moreover, satisfaction was high after the intervention (mean = 4.5/5), and when comparing the two pedagogical approaches the students showed a clear preference for the program implemented with the concepts highlighted such as interactivity, in-depth work, group work, and autonomy. A multifaceted interactive pedagogy program could have a significant impact on the results of the theoretical concepts presented and on satisfaction as well as increased investment by students in learning anatomy.  相似文献

Total Protein of Whole Saliva as a Biomarker of Anaerobic Threshold     

Miguel Sordi Bortolini Junior  Guilherme Gularte De Agostini  Ismair Teodoro Reis  Romeu Paulo Martins Silva Lamounier  Jeffrey B. Blumberg  Foued Salmen Espindola 《Research quarterly for exercise and sport》2013,84(3):604-610

Saliva provides a convenient and noninvasive matrix for assessing specific physiological parameters, including some biomarkers of exercise. We investigated whether the total protein concentration of whole saliva (TPWS) would reflect the anaerobic threshold during an incremental exercise test. After a warm-up period, 13 nonsmoking men performed a maximum incremental exercise on a cycle ergometer. Blood and stimulated saliva were collected during the test. The TPWS anaerobic threshold (PAT) was determined using the Dmax method. The PAT was correlated with the blood lactate anaerobic threshold (AT; r = .93, p < .05). No significant difference (p = .16) was observed between PAT and AT. Thus, TPWS provides a convenient and noninvasive matrix for determining the anaerobic threshold during incremental exercise tests.  相似文献   

Circular formation control for cooperative target tracking with limited information     

Lara Briñón-Arranz  Alexandre Seuret  António Pascoal 《Journal of The Franklin Institute》2019,356(4):1771-1788

This paper addresses the problem of encircling and tracking a moving target with a fleet of unicycle-like vehicles. A new control law is developed to steer the vehicles to an evenly spaced formation along a circumference, the center of which tracks the motion of the target. The strategy proposed relies only on the relative positions of the agents with respect to the target, expressed in the local frame of each vehicle. The absolute position, velocity and acceleration of the target are unknown. Additionally, the robustness of the proposed control law in the presence of external disturbances is analyzed. Communication among agents is used to maintain the vehicles equally spaced in the circular formation. Simulation results illustrate the effectiveness of the proposed strategies.  相似文献

Assessing Teachers’ Attitudes Towards Students with Mental Health Disorders in 16 Postsecondary Institutions in Quebec     

Myreille St-Onge  Alexandre Lemyre 《International Journal of Disability, Development & Education》2018,65(4):459-474

The number of students with mental health disorders (MHDs) in postsecondary institutions is increasing. Teachers’ attitudes are among the main factors that influence these students’ academic success. Unfortunately, their attitudes are little studied, in part because of lack of validated scales. Therefore, this article has two purposes: (1) analyse the construct validity of new scales assessing teachers’ attitudes, as well as existing scales without an established construct validity; and (2) report the correlations between the variables assessed in these scales, with a special focus on two variables: (a) teachers’ negative attitudes; and (b) the measures offered to students by teachers. The participants are 232 teachers from 16 French and English CEGEPS in Quebec, Canada. The questionnaire includes three scales created by the research team and three scales from the Mental Illness Awareness Survey. Correlational and factor analyses were conducted. The scales present good construct validity. Four variables were associated with the two variables of interest: confidence in one’s ability to convince a student to seek help; familiarity with MHDs; knowledge and understanding of MHDs; favourable perception of the accommodations offered by adapted and psychosocial services. Based on these results, strategies are proposed to improve teachers’ attitudes.  相似文献   

A model for the effective engagement of all stakeholders in engineering education and its pilot implementation     

Bárbara Filipa Casqueria Coelho Gabriel  João Alexandre Dias-de-Oliveira  Victor Fernando Santos Neto  António Gill D’Orey De Andrade-Campos 《European Journal of Engineering Education》2018,43(6):950-966

Methodologies for engineering learning and teaching (MELT) approach aims to enhance the attractiveness of education through science, technology, engineering and mathematics (STEM) among young people, while promoting awareness of future careers in these areas. To this end, students’ expectations are considered within university programmes, aiming to an increased engagement in STEM careers. To accomplish these goals, a new and integrated approach (MELT) is presented, involving the main stakeholders in both scientific education and society. An education framework is presented, providing guidelines for an improved collaborative approach to STEM education in the future. Results from the pilot implementation of MELT are presented, from a small-scale education parliament prototype. From these initial stage and results, it is seen that there is a need for a proper alignment of expectations from all involved stakeholders, concerning the engineering education towards society’s demands.  相似文献
