Determining the feasibility and acceptability of a garden-based nutrition curriculum for preschoolers

Obesity rates around the nation have risen to epidemic proportions. Rates of childhood obesity are at very high levels with 24.4% of preschool-aged children in the U.S. currently considered as overweight or obese. The percentage of childhood obesity is much higher in the southern part of the United States as compared to the rest of the nation. Minority populations, especially African American and Hispanic, are affected more than other ethnic groups. Obesity prevention programs are needed targeting young children <6 years of age from minority populations. Currently, there are few obesity prevention programs that have been implemented and evaluated in children <6 years of age. Gardening programs have been successful in improving the health status of elementary school children by increasing fruit and vegetable intake and increasing preferences for healthier food choices. However, there is no evidence of the feasibility and acceptability of a garden-based obesity prevention program among preschoolers. This pretest study, a classroom-based gardening curriculum program with 16 lesson plans and coordinating activities for preschool age children (3-5 years old) enrolled in Head Start, provides the opportunity to address this need. The study included 103 preschoolers from two centers and 9 teachers or teachers' aides. Qualitative data on feasibility and acceptability was collected from process evaluation forms of individual lesson plans and focus groups with teachers. Teacher questionnaires assessed individual teacher characteristics and provided feedback regarding the curriculum. Quantitative measures of teachers' self-efficacy, attitudes, and knowledge pertaining to nutrition were analyzed from pre and post-test surveys. Results revealed this preschool garden-based nutrition curriculum was both feasible and acceptable. The program improved teacher's self-efficacy, knowledge, and attitudes about nutrition, with teacher's confidence in ability to teach a gardening curriculum increasing from a mean score of 2.14 to 3.00 from pre to post test (P value = 0.0046). These results indicate implementing garden-based nutrition lessons within preschools is achievable. Employing garden-based nutrition lessons in the classroom is the first step in teaching children about nutrition and gardening concepts. Constructing gardening beds for more hands-on learning is the next proposed step in the larger parent study of this program.^

Is family medicine meeting the HIV/AIDS challenge? A national survey of family physicians' beliefs, clinical competence, and experience regarding HIV disease

A national sample of family physicians was surveyed to (1) assess family physicians' beliefs about the human immunodeficiency virus (HIV) and individuals at risk for infection, their clinical competence regarding HIV-related issues, and their experiences with HIV disease; (2) present conclusions to the American Academy of Family Physicians (AAFP) to effect the development of an early clinical care protocol and a continuing medical education curriculum; and (3) collect base-line data for use in the evaluation of an early clinical care protocol and a continuing medical education curriculum, in the case that such programs are developed and disseminated. After considering retired or deceased respondents, of the 2,660 physicians surveyed, 1,678 (63.7%) responded. The resulting sample was representative of the active members of the AAFP. About 77% of the respondents were unable to accurately identify the universal precautions for blood and body fluids to prevent occupational transmission of HIV or hepatitis B virus (HBV). Residency trained and board certified physicians expressed fewer "external constraints," such as fear of losing patients, obviating them from providing treatment to individuals with HIV disease (p =.004 and p $<$.001, respectively). These physicians also manifested fewer "internal constraints" to the provision of HIV treatment, such as fear of becoming infected (p $<$.001 and p =.012, respectively). Residency trained physicians also expressed a greater comfort with discussing sexually-related topics with their patients than did non-residency trained physicians (p $<$.001). There were 67.1% of the physicians surveyed who reported never providing treatment to an individual with HIV disease. Residency trained and board certified physicians expressed a greater likelihood to provide treatment to HIV-infected patients (p $<$.001) than non-residency trained and non-board certified physicians.^ Among the various primary care specialties, family medicine is especially vulnerable to the current challenges of HIV/AIDS. These challenges are augmented by the epidemiologic pattern that characterizes AIDS. For the past several years, we have seen AIDS in this country assume a similar pattern to that seen in most other countries; HIV is becoming increasingly prevalent in the heterosexual population as well as in locations removed from metropolitan centers. This current phase of the epidemic generates greater pressures upon primary care physicians, particularly family physicians, to become better acquainted with the means to provide early care to HIV/AIDS patients and to prevent HIV/AIDS among their patients. Family medicine is especially appropriate for providing care to HIV patients because family medicine involves treatment to all age groups and conditions; other primary care specialties focus on limited patient populations or specific conditions. Family physicians should be armed with the expertise to confront HIV/AIDS. However, family physicians' clinical competence and experience with HIV is not known. The data collected in this survey describes their competencies, attitudes, and experiences. ^

¿Para qué educar en ciencias naturales, ambiente y salud hoy en Argentina?

Este artículo presenta un análisis de representaciones sociales (RS) sobre finalidades de la educación en ciencias naturales y rol docente, enmarcado en una experiencia de formación en servicio y trabajo colaborativo con docentes de diferentes niveles educativos de la Provincia de Buenos Aires.

Where does Philippine education go? : the "K to 12" program and reform of Philippine basic education

In 2012 the Philippines launched its "K to 12" Program, a comprehensive reform of its basic education. Through this reform, the Philippines is catching up with global standards in secondary education and is attaching a high value to kindergarten. The structure, curricula, and philosophy of the education system are undergoing reform and improvement. The key points of the new policy are "preparation" for higher education, "eligibility" for entering domestic and overseas higher educational institutions, and immediate "employability" on graduating, all leading toward a "holistically developed Filipino". This policy appears admirable and timely, but it faces some pedagogical and socioeconomic problems. The author wants to point out in particular that the policy needs to address gender problems and should be combined with demand-side approaches in order to promote poverty alleviation and human development in the Philippines.

Gender-preferential intergenerational patterns in primary education attainment : a quantitative analysis of a case of rural Mindanao, the Philippines

The Philippines has achieved a relatively high standard of education. Previous researches, most of which deal with Luzon Island, have indicated that rural poverty alleviation began partly due to the increased investment in education. However, the suburban areas beyond Luzon Island have rarely been studied. This study examines a case from rural Mindanao, and investigates the determinants and factors associated with children's education, with a special focus on delays in schooling, which may be a cause of dropout and holdover incidences, as well as exploring gender-specific differential patterns. The result shows that after controlling other socioeconomic attributes, (1) delays in schooling, as well as years completed, are more favorable for girls than boys; (2) the level of maternal education is equally associated with the child(ren)’s education level regardless of their gender; and (3) paternal education is preferentially and favorably influential to the same-gender child(ren), i.e., son(s). To reduce the boy-unfriendly gender bias in primary education, this study suggests two future tasks, i.e., providing boy-specific interventions to enhance the magnitude of the father-son educational virtuous circle, and comparing the magnitude of gender-equal maternal education influence and boy-preferential paternal education influence to specify which effect is larger.

Traditional education vs modern education. What is the impact of teaching techniques' evolution on students learning process?

The main objective of this article is to focus on the analysis of teaching techniques, ranging from the use of the blackboard and chalk in old traditional classes, using slides and overhead projectors in the eighties and use of presentation software in the nineties, to the video, electronic board and network resources nowadays. Furthermore, all the aforementioned, is viewed under the different mentalities in which the teacher conditions the student using the new teaching technique, improving soft skills but maybe leading either to encouragement or disinterest, and including the lack of educational knowledge consolidation at scientific, technology and specific levels. In the same way, we study the process of adaptation required for teachers, the differences in the processes of information transfer and education towards the student, and even the existence of teachers who are not any longer appealed by their work due which has become much simpler due to new technologies and the greater ease in the development of classes due to the criteria described on the new Grade Programs adopted by the European Higher Education Area. Moreover, it is also intended to understand the evolution of students’ profiles, from the eighties to present time, in order to understand certain attitudes, behaviours, accomplishments and acknowledgements acquired over the semesters within the degree Programs. As an Educational Innovation Group, another key question also arises. What will be the learning techniques in the future?. How these evolving matters will affect both positively and negatively on the mentality, attitude, behaviour, learning, achievement of goals and satisfaction levels of all elements involved in universities’ education? Clearly, this evolution from chalk to the electronic board, the three-dimensional view of our works and their sequence, greatly facilitates the understanding and adaptation later on to the business world, but does not answer to the unknowns regarding the knowledge and the full development of achievement’s indicators in basic skills of a degree. This is the underlying question which steers the roots of the presented research.

Nuevos métodos y herramientas para la creación y utilización de recursos multimedia en la educación

La educación y los entornos educativos están en constante evolución. Tanto alumnos como educadores cambian de hábitos, de maneras de aprender, de gustos, de dispositivos que manejan y de aplicaciones que usan regularmente entre otras cosas. Todos estos cambios vienen acompañados y fomentados en gran medida por la evolución paralela que experimenta la tecnología, tanto software en los programas utilizados, como hardware en los dispositivos y capacidades de éstos. La educación debe también adaptarse a estos cambios, tanto personales como tecnológicos y sacar el mayor provecho de ellos. El uso de Sistemas de Gestión del Aprendizaje está muy extendido en todos los centros educativos. Estos sistemas poseen un gran número de características y funcionalidades que permiten desde la aplicación de un modelo didáctico totalmente tradicional en el que el profesor imparte un contenido y los alumnos lo reciben a uno totalmente innovador en el que ocurren procesos totalmente diferentes. Por otro lado, el potencial que ofrecen los recursos multimedia no ha sido completamente aprovechado en la educación y supone una gran oportunidad. Esta tesis doctoral propone un conjunto de métodos y herramientas para la creación y el uso de recursos multimedia en la educación. Para ello el desarrollo de esta tesis parte de la definición de un modelo didáctico social, colaborativo y centrado en el alumno que servirá de hilo conductor y que integrará los diferentes y métodos y herramientas estudiados y desarrollados. En un primer paso se identifican varias herramientas y métodos para el aula, tales son la grabación de clases, donde se crea y posteriormente se mejora un carrito portátil de grabación que da muy buen resultado, las herramientas de grabación de screencast y la videoconferencia. Estas herramientas además se integran en una plataforma colaborativa dando lugar a una arquitectura completa y escalable que permite la realización de dichas actividades y la interconexión sencilla con el Sistema de Gestión del Aprendizaje. A continuación y ya en un entorno totalmente online se desarrolla una nueva plataforma de e-learning llamada Virtual Science Hub (ViSH) que consta de cuatro funcionalidades principales, red social, videoconferencia, repositorio educativo y herramienta de autor. En esta plataforma se aplicaron técnicas de recomendación proactiva tanto de recursos educativos como de otros usuarios similares. Por último se validó el modelo educativo completo usando algunas de las herramientas identificadas y desarrolladas en dos escenarios diferentes con gran éxito. Finalmente, esta tesis discute las conclusiones obtenidas a lo largo de la extensa investigación llevada a cabo y que ha propiciado la consecución de una buena base teórica y práctica para la creación de herramientas y métodos para la generación y el uso de recursos multimedia en la educación. ABSTRACT Education and learning environments are constantly evolving. Students and educators change the things their habits, their ways of learning, the things they like or the devices and applications that they use regularly among other things. All these changes are accompanied and fostered by the parallel evolution that technology experiences, both in the software programs used as in the hardware and capabilities of these devices. Education must also adapt to these changes, both personal and technological and get the most out of them. Learning Management Systems are widely used in all educational centers. These systems have a large number of features and functionalities. They allow from the implementation of a traditional teaching model in which the teacher gives content and students receive it to one absolutely innovative teaching model where totally different processes occur. Furthermore, the potential of multimedia resources has not been fully exploited in education and can be a great opportunity. This thesis proposes a set of methods and tools for the creation and use of multimedia in education. The development of this thesis starts with the definition of a social, collaborative and learner-centered model, that serves as a common thread and that integrates different tools and methods studied and developed. In a first step, several tools and methods for the classroom are identified, such as recording, where a portable kit is created and then improved giving very good results, screencast recording and videoconferencing. These tools also are integrated into a collaborative platform resulting in a complete, scalable architecture that enables the execution of such activities and a simple interconnection with the Learning Management System. In an fully online environment a new e-learning platform called Virtual Science Hub (ViSH) is created. It consists of four main features that combine and complement each other, social network, videoconferencing, educational repository and authoring tool. In this platform proactive recommendation of both educational resources and similar users is applied. In a last step the entire educational model using some of the tools identified and developed is successfully validated in two different scenarios. Finally, this thesis discusses the findings obtained during the extensive research carried out and has led to the achievement of a good theoretical and practical basis for the development of tools and methods for the generation and use of multimedia in education.

Strengthening and measuring project management competences of engineering students

Since 2010 the Industrial Engineering School at Universidad Politécnica de Madrid (ETSII UPM) has its Plan Study accredited by ABET. Since then a big motivation has been promoted from the management team encouraging teachers to work on the measurement and strengthening of student¿s competences. Generic skills or behavior acquired significant importance in the workplace, particularly in relation to project management. Because of this, and framed within the requirements of the European Higher Education Area (EHEA), the curriculum of the new degrees are being developed under the competence-based learning. This situation leads to the need to have a clear measurement tool skills as a basis for developing them within the curriculum. A group of multidisciplinary teachers have been working together during two years to design measuring instruments valid for engineering students.

A realidade das entidades científicas e a formação de professores de física: uma análise sociocultural

O objetivo da presente tese é realizar uma abordagem acerca da realidade das entidades científicas no contexto da formação de professores de física. A literatura em ensino de ciências destaca a importância do entendimento de aspectos da natureza da ciência por professores. Dentre esses aspectos, exploramos a questão da realidade das entidades inobserváveis descritas pelas teorias científicas, tratando sobretudo de critérios utilizados para a caracterização dessa realidade por licenciandos, bem como possíveis influências na constituição desses critérios. Consideramos que um professor de física, durante sua atuação profissional, precisará lidar com a questão da realidade de entidades não acessíveis aos sentidos, tendo talvez de explicar em que se baseia uma proposição sobre sua existência. No desenvolvimento do presente trabalho, trouxemos alguns elementos de uma discussão que se dá no âmbito filosófico a respeito do realismo científico e também abordamos formulações teóricas que tratam da questão da realidade em perspectivas que se referem ao campo cotidiano e ao senso comum. Como referencial mais geral, utilizamos uma abordagem sobre cultura, que aponta para a influência de diversas estruturas culturais nas formas de entendimento do mundo e permite conceber a ciência como uma dessas estruturas. Entre outras coisas, a aprendizagem da ciência envolveria a compreensão de suas formas específicas de atribuir realidade, em contraposição às formas de outras estruturas culturais. Foram desenvolvidos três estudos, com análises fundamentadas em metodologias qualitativas. No primeiro, investigamos critérios usados por licenciandos em física para definir a realidade de entidades da ciência e de entes relacionados a outros domínios; no segundo, analisamos formas pelas quais certas entidades científicas são caracterizadas e tomadas como reais em uma coleção de livros didáticos de física do ensino superior; e, por fim, o terceiro consistiu na construção e utilização de um heurístico, com o objetivo de proporcionar reflexões acerca de questões relacionadas ao conhecimento científico e a elementos de outras estruturas culturais e foram analisadas as entrevistas de quatro estudantes de licenciatura sobre o uso desse instrumento. Os resultados obtidos parecem mostrar que há influência de elementos vindos de fora da ciência nos critérios utilizados por estudantes para a definição da realidade das entidades. Além disso, mostram que esse tema não é comumente trazido à reflexão dos alunos, o que não contribui para a reelaboração dos critérios de realidade já trazidos por eles de outros campos que não o científico. O heurístico utilizado no terceiro estudo serviu para trazer à tona as bases do pensamento dos estudantes e lhes indicar certos elementos para reflexão; existiram diferenças nos tipos de reflexão suscitados pelo instrumento, o que consideramos ser uma espécie de \"contextualização cultural\" na maneira de compreender as questões trazidas por ele. O desenvolvimento dos três estudos nos permitiu compreender alguns aspectos relevantes sobre os modos de entendimento das entidades da ciência e pensar sobre suas formas de tratamento em um curso de física.

Processo de reflexão orientada na formação de professores dos anos iniciais: concepções e práticas sobre o ensino de ciências

Esta investigação, de natureza qualitativa, visou conhecer as concepções e práticas de professores dos anos iniciais sobre o ensino de ciências e promover reflexões sobre tal ensino. O trabalho teve como base o Processo de Reflexão Orientada (PRO), uma estratégia para o desenvolvimento profissional a partir do enfoque de questões da prática docente. As questões de investigação foram: Como professores dos anos iniciais concebem, refletem, planejam e realizam o ensino de Ciências? E como refletem e realizam o ensino de Ciências a partir de um Processo de Reflexão Orientado (PRO)? E, ainda, como, a partir de um Processo de Reflexão Orientado (PRO) para professores dos anos iniciais do Ensino Fundamental avaliam o seu próprio desenvolvimento profissional? Os dados foram obtidos a partir de questionários, entrevistas, planejamentos escritos e de vídeogravações dos encontros e de aulas ministradas. A análise dos dados foi feita a partir da análise de conteúdo. As ideias manifestadas pelas professoras sobre ensino de ciências foram classificadas dentro de uma abordagem oscilando entre cognitivista e sócio-cultural. Seus modelos didáticos revelaram ideias pouco consistentes sobre o processo de ensino e aprendizagem, com pouca coerência em relação a modelos de orientação construtivista. Cada professora propôs uma sequência de ensino visando alcançar graus mais complexos. As sequências foram discutidas, novas reflexões foram realizadas e reelaborações foram propostas. As aulas desenvolvidas evidenciaram um progresso de Lívia com relação à participação dos alunos, com a proposição de uma situação-problema, da consideração das ideias prévias dos alunos, embora apresentasse ainda dificuldade de promover uma discussão orientada, que pudesse favorecer a argumentação dos alunos e a compreensão do fenômeno. Já, nas aulas de Roberta observaram-se atividades que privilegiaram a participação dos alunos. Nas aulas das duas professoras ficaram evidentes a proposição de um problema e a sistematização do conhecimento, a partir da elaboração de sínteses orais e escritas e da apresentação para outras classes. Embora as professoras valorizassem o ensino de ciências e a participação ativa das crianças, havia dificuldades para a realização de aulas de ciências por investigação, pois não consideravam a problematização, a exploração das ideias dos alunos, a sistematização do conhecimento e as explicações científicas. O processo de reflexão orientada (PRO) mostrou ser uma estratégia importante para o desenvolvimento profissional dessas professoras, possibilitando reflexões significativas sobre a própria prática, bem como a tomada de consciência de uma nova sistematização das ações docentes, com vistas a uma atuação mais eficaz para promover o ensino de Ciências por investigação.
