Peer and near-peer teaching programs are common in medical undergraduate courses. However, there are no studies that have investigated the effectiveness of a near-peer teaching program on the academic performance of undergraduate students pursuing sport and exercise science coursework. This study was conducted to analyze the effectiveness of such a program for students who participated in a course on the functional anatomy of the locomotor apparatus. A total of 39 student participants were divided into two groups: students in one group voluntarily attended at least one session of a near-peer teaching program, and students in the other group attended no sessions. The final grade (range 0–100%) was recorded and used as an indicator of academic performance. The final grade of students who attended the near-peer teaching program (69.5 ± 16.0%) was 38.7% higher (P = 0.002, d = 1.06) than those who did not (50.1 ± 20.4%). When the academic performance of the same students was evaluated in another course (exercise physiology) that did not offer a near-peer teaching program, there were no significant differences between the groups (students who attended or did not attend the near-peer teaching program). A significant positive association was found between near-peer teaching program frequency and the number of students approved and not approved in the course (P = 0.041). A significant difference (P = 0.001) was found in the attendance at regular classes between the group who participated in the near-peer teaching program (median: 62 hours; IQR [interquartile ranges]: 4.0 hours) and those who did not (median: 58 hours; IQR: 4.0 hours). Gender was not a moderating factor on academic performance or near-peer teaching program attendance. These results highlight the effectiveness of a near-peer teaching program on the academic performance of students from a sport and exercise science degree program while enrolled in an anatomy course.

The geography of school choice critically shapes families’ educational opportunities. Residential segregation, social inequalities and the educational marketplace interact in complex ways and produce spatialised educational opportunities for families. This paper analyses the link between these dimensions and how they structure families’ educational opportunities in the city of Madrid. Based on several administrative datasets that capture students’ residential location, their socio-economic position, the schools they attend and the characteristics of school supply, our analysis reveals the uneven spatial distribution of the different school modalities in Madrid, where advantaged families and neighbourhoods have more diversified and socio-economically homogenous nearby schooling options. The results also depict the way the city is spatially divided along a continuum of ‘privileged’ residential and educational assets. The paper reflects on how reforms expanding school choice and diversification of the educational market undertaken by the regional government may have increased the link between residential and school segregation.  相似文献

The adjectives “generic”, “subgeneric”, “specific”, and “individual” are proposed to be added to the term “quantity”, depending on the case, in order to diminish the ambiguity of this term and to classify the different types of quantities.  相似文献

The conditions under which discrete-time nonlinear affine systems possess fading memory are explored. A sufficient condition is given based on discrete-time Lyapunov theory; whereas a necessary condition is provided based on the relationship between the stability and the continuity of this system.  相似文献

The article compares educational regionalisation in Europe and Latin America. This analysis unveils the influence of three social phenomena in the two case studies, namely power, fields of activity and knowledge. Mostly, it focuses on the initiatives led by the European Union and the Organisation of Ibero-American States in order to implement large strategic, multi-government educational plans in each continent. The actions of international political players, the theories (or ‘ontologies’) embedded in these devices and the consequences for sub-national politics are observed.  相似文献

  • The pandemic can be seen as an opportunity to revisit the justification for conferences and how they should be run to avoid elitism, climate impact, and diversity.
  • 2020 saw a wealth of different approaches to events, including financing, technologies, scheduling, and the meaning of the term ‘live’.
  • Engaging attendees and providing networking opportunities are considered the main obstacle to virtual events, but can social networking lessons help resolve – or even improve – this?
  • It may take some time for online event programming to achieve the right balance of flexibility versus ‘buzz’ to meet a conference's key objectives: knowledge sharing and peer interaction.
  • Live broadcasting is on the rise, but the on‐demand video model is gaining popularity as it ensures high‐quality presentation recordings and consistency of experience.
  • Over time, technical challenges of online meetings will resolve, with competition leading to more reasonable pricing, customers becoming savvier, and vendors learning from experience.
