“Just like us”: Increasing awareness,prompting action and combating ageism through a critical intergenerational service learning project

In the Through their Eyes Project health sciences students are partnered with older adults to explore and assess the age-friendliness of their neighborhood. Using an innovative data collection tool – ‘moving interviews’ – these intergenerational research teams learn about the community and each other by traveling, observing, and discussing these landscapes together. The research project culminates in a community forum where findings are presented to government officials, the housing association and aging organizations. In addition to completing the research project, students are required to keep a journal to reflect on their experience.

The purpose of this study was to explore students experience participating in a critical intergenerational service learning project. Two research questions guided this inquiry: What was the experience for students and, what elements of the project are important to that experience?

Student journals collected over 5 years from 191 students comprised the data for this study. Data were analyzed using a 6-phase thematic analysis process.

Two key findings related to student experience emerged from the study: increased awareness and prompted to action. Elements of the course found significant to this experience included an aging simulation activity and the specific design of the project.

The paper concludes with suggestions for developing and integrating critical service-learning pedagogy into gerontological education.

Applying the EFQM model to golf course management

The European Foundation for Quality Management (EFQM) Excellence Model provides guidance and support for business organisations to improve their quality management. This goal is attained by examining the relations among the several criteria that are defined and included in the model – the Enablers and the Results – albeit without going deeply into their empirical correlations. Our research focuses on the sport industry and, more particularly, on golf-related services and facilities. We analyse their management and performance. The goal is to conduct an empirical study of golf courses making up the supply in a Spanish inland region. On the basis of data and assessments contributed by the participating sample – and by resorting to multivariate statistical analysis – we pinpoint the influence of all Enablers identified by the EFQM Model, as well as their impact on the Results criteria. Correlations designed and empirically quantified make it possible for us to confirm the theoretical interrelations that the EFQM Model proposes between the defined criteria. The structural model thus obtained allows us to design a map that plots the relationships across the several criteria defined by the EFQM Model, one which portrays present-day approaches to management put into practice by the golf courses under scrutiny.     

Relationships between everyday knowledge and scientific knowledge: understanding how matter changes

This paper analyses the representations held by adolescents and university students in relation to the mechanism for explaining changes in matter (changes of state, dissolutions, expansions and chemical reactions) in terms of the kinetic theory. The answers to a questionnaire were analysed by considering the proportion of correct answers and the use of alternative conceptions. The results show that understanding of explanatory mechanisms of changes in matter is affected by age and instruction level and content of the problem. The main conception that competes with the kinetic model is the attribution to the particles of the changes observed, at a macroscopic level. This is more evident in changes of state and expansions than in other changes. This confusion results from a failure to differentiate properly between the represented reality and the model that represents it. In conclusion, analysis has shown once more students' difficulties in going beyond apparent reality or integrating the data obtained from it into the scientific models they learn at school.     

Detection of Misconceptions about Colour and an Experimentally Tested Proposal to Combat them

We study the misconceptions about colour that most people hold, determining the general phenomenological laws that govern them. Concept mapping was used to combat the misconceptions which were found in the application of a test specifically designed to determine these misconceptions, while avoiding the possible misleading inductions that could have arisen from the use of everyday language. In particular, care was taken to avoid the distorting effect that the use of the verb ‘to be’ applied to coloured objects could have on the responses. The misconceptions found were shown to have an internal consistency in the form of authentic mini-theories (implicit theories). We compared experimentally the results of two different teaching methods applied to combat these misconceptions. This study was conducted with 470 undergraduates of the University of Extremadura. We analysed the persistence over time of their learning made to overcome those misconceptions. The students were divided randomly into an experimental group (EG) and a control group (CG). To combat their misconceptions, EG were taught following a method based on the use of concept maps, and CG were taught following traditional teaching methods. The results of a pre-test and a post-test were compared for the two groups, finding statistically significant differences. The results allowed the principal working hypothesis to be accepted—concept maps are learning tools which foster conceptual change and allow misconceptions to be eradicated via meaningful learning maintained over time, i.e. EG acquired a relative long-lasting gain in learning that was superior to that acquired by CG.

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.     

Design and Application of Interactive Simulations in Problem-Solving in University-Level Physics Education

In recent years, interactive computer simulations have been progressively integrated in the teaching of the sciences and have contributed significant improvements in the teaching–learning process. Practicing problem-solving is a key factor in science and engineering education. The aim of this study was to design simulation-based problem-solving teaching materials and assess their effectiveness in improving students’ ability to solve problems in university-level physics. Firstly, we analyze the effect of using simulation-based materials in the development of students’ skills in employing procedures that are typically used in the scientific method of problem-solving. We found that a significant percentage of the experimental students used expert-type scientific procedures such as qualitative analysis of the problem, making hypotheses, and analysis of results. At the end of the course, only a minority of the students persisted with habits based solely on mathematical equations. Secondly, we compare the effectiveness in terms of problem-solving of the experimental group students with the students who are taught conventionally. We found that the implementation of the problem-solving strategy improved experimental students’ results regarding obtaining a correct solution from the academic point of view, in standard textbook problems. Thirdly, we explore students’ satisfaction with simulation-based problem-solving teaching materials and we found that the majority appear to be satisfied with the methodology proposed and took on a favorable attitude to learning problem-solving. The research was carried out among first-year Engineering Degree students.     

A teaching–learning sequence on a socio-scientific issue: analysis and evaluation of its implementation in the classroom*

This study examines the effectiveness of a teaching–learning sequence (TLS) to improve the understanding of the influences and interactions between a technology (mining) and society. The aim of the study is also to show the possibility of both teaching and assessing the most innovative issues and aspects of scientific competence and their impact on the understanding of the nature of science. The methodology used a quasi-experimental, pre–post-test design with a control group, with pre–post-test differences as the empirical indicators of improved understanding. Improvements were modest, as the empirical differences (pre–post and experimental–control group) were not large, but the experimental group scored more highly than the control group. The areas that showed improvement were identified. The paper includes the TLS itself and the standardized assessment tools that are functional and transferable to other researchers and teachers.
