Associations between teacher support and students' fruit and vegetable consumption in low-income elementary schools in central Texas

Background. Similar to parent support in the home environment, teacher support at school may positively influence children's fruit and vegetable (FV) consumption. This study assessed the relationship between teacher support for FV consumption and the FV intake of 4th and 5th grade students in low-income elementary schools in central Texas. Methods. A secondary analysis was performed on baseline data collected from 496 parent-child dyads during the Marathon Kids study carried out by the Michael & Susan Dell Center for Healthy Living at the University of Texas School of Public Health. A hierarchical linear regression analysis adjusting for key demographic variables, parent support, and home FV availability was conducted. In addition, separate linear regression models stratified by quartiles of home FV availability were conducted to assess the relationship between teacher support and FV intake by level of home FV availability. Results. Teacher support was not significantly related to students' FV intake (p = .44). However, the interaction of teacher support and home FV availability was positively associated with students' FV consumption (p < .05). For students in the lowest quartile of home FV availability, teacher support accounted for approximately 6% of the FV intake variance (p = .02). For higher levels of FV availability, teacher support and FV intake were not related. Conclusions. For lower income elementary school-aged children with low FV availability at home, greater teacher support may lead to modest increases in FV consumption.^

A characterisation of passive and active interactions and their influence on student's achievement using Moodle LMS Logs

During the last years, there has been much concern about learning management systems' (LMS) effectiveness when compared to traditional learning and about how to assess students' participation during the course. The tracking and monitoring capabilities of most recent LMS have made it possible to analyse every interaction in the system. The issues addressed on this study are: a) Is LMS student's interaction an indicator of academic performance?; b) Are different results in performance expected between distance and in-class LMS-supported education?; c) How can LMS interactions from logs be categorised?; d) May this categorisation detect 'learning witnesses'? To answer these questions, a set of interaction types from Moodle LMS activity record logs has been analysed during two years in online and in-class Master's degrees at the UPM. The results show partial or no evidence of influence between interaction indicators and academic performance, although the proposed categorisation may help detect learning witnesses.

Learning Analytics and Interactions in Virtual Learning Environments. A Comparative Study of Typologies and their Relationship with Academic Performance

Analysis of learning data (learning analytics) is a new research field with high growth potential. The main objective of Learning analytics is the analysis of data (interactions being the basic data unit) generated in virtual learning environments, in order to maximize the outcomes of the learning process; however, a consensus has not been reached yet on which interactions must be measured and what is their influence on learning outcomes. This research is grounded on the study of e-learning interaction typologies and their relationship with students? academic performance, by means of a comparative study between different interaction typologies (based on the agents involved, frequency of use and participation mode). The main conclusions are a) that classifications based on agents offer a better explanation of academic performance; and b) that each of the three typologies are able to explain academic performance in terms of some of their components (student-teacher and student-student interactions, evaluating students interactions and active interactions, respectively), with the other components being nonrelevant.

Applied genre analysis: the case of introductions in spanish teacher trainees curricular design documents

A host of studies over the years have been published on introductions to research articles across a variety of fields. However, much less attention has been paid to professional or workplace introductions as well as student written introductions. This study aims to redress this imbalance by studying the writing samples of four primary English teacher trainees’ introductions to curricular design i.e. the document candidates must present to an examination board in Spain. This genre can be considered occluded in that exemplars are private and confidential and not readily available to the aspiring candidate. Three recurrent moves were identified, namely, explaining the importance of curricular design, providing background and defining concepts. Instances of self-glorification (Bhatia 1996) were revealed. The implications of the findings can have a positive effect on students’ future writing. RESUMEN. Se han publicado varios estudios en los últimos años sobre las introducciones de los artículos de investigación en varios campos. Sin embargo, se ha prestado mucha menor atención a las introducciones en los ámbitos profesionales o las introducciones en el lugar de trabajo, así como a las introducciones escritas por estudiantes. Este estudio tiene por objeto corregir este desequilibrio mediante el análisis de cuatro introducciones redactadas por candidatos para las oposiciones públicas de profesores de inglés de primaria. Este género se puede considerar oculto puesto que las muestras de dichas introducciones no están publicadas. El análisis de estas introducciones muestra que hay tres movimientos recurrentes: una explicación de la importancia del diseño curricular, definición del contexto educativo y, por último, definición de conceptos. Hay ejemplos en este estudio empírico de auto-promoción (Bhatia 1996). Las implicaciones de los resultados pueden tener un efecto positivo en la escritura de estos estudiantes en el futuro.

Aplicación Android para el aprendizaje de inglés nivel B2 : extensión del ILLLab

Desde el inicio de la globalización, el aprendizaje de la lengua inglesa se ha instaurado como una necesidad. Hoy en día, con la adopción del Espacio Europeo de Educación Superior este lenguaje no sólo se impone como un requisito para los estudiantes sino que se exige un nivel B2, lo cual significa un esfuerzo mayor tanto como para el alumno como para el profesor a la hora de hacer de este ejercicio un hábito y lograr la evaluación continua de los mismos. Este proyecto intenta extender las funcionalidades de una aplicación existente llamada Illlab con ejercicios que se adapten al nivel B2 y permitan la interacción entre alumnos durante la realización de estos ejercicios. El objetivo de esta aplicación es el de desarrollar ejercicios extra en la aplicación Illlab que añadan complejidad para el aprendizaje de inglés de un nivel B2 y que además se puedan realizar actividades entre los alumnos. La idea es hacer una aplicación de preguntas y respuestas “multiple choice” con cuatro opciones por pregunta. El fuerte de este juego está en presentar material variado sobre uso de la lengua y además permitir el juego entre varios alumnos. La extensión de ILLLab se plantea como un proyecto para desarrollar interfaces y funcionalidades adicionales en la antigua aplicación. La principal funcionalidad que se añade es un juego de preguntas y respuestas con opciones múltiples para un nivel B2 y las interfaces responden a necesidades de intercambio y manejo de contenido por Internet mediante estándares aceptados en el mundo del aprendizaje digital tales como Common Cartridge o SCORM. Este proyecto simplemente adapta la aplicación para su uso en un entorno de evaluación de actividades en el cual el profesor tiene acceso a las actividades que realizan los alumnos de un curso para su posterior evaluación. Antiguamente ILLLab sólo contenía ejercicios que se llevaban a cabo en el dispositivo móvil por lo que el control de estas actividades no era posible. La mejora se presenta como una interfaz Common Cartridge para el manejo del contenido, una interfaz de comunicación sobre servicios web tipo REST y el manejo de base de datos mediante Hibernate que agrupa una serie de librerías Java para la persistencia de objetos de la base de datos. ABSTRACT. Since the onset of globalization, the learning of the English language has become as a necessity. Today, with the adoption of the European Higher Education Area this language is not only imposed as a requirement for students but a B2 level is required, which means a greater effort both to the student and teacher when it comes to make the learning exercise a habit and achieve continuous evaluation of students. This project aims to extend the functionality of an existing application called Illlab with an exercise that suits the B2 level and allow interaction between students while performing these exercises. The purpose of this application is to develop an additional exercise in the application Illlab that adds complexity for learning English at B2 level and also enables the interaction among students. The main idea is to make an application in multiple choices style with four options. The strength of this game is to present varied material on use of Enlgish and also allow play between two students. ILLLab extension is conceived as a project to develop interfaces and additional functionalities in the old application. The main functionalities added are a game of questions and answers with multiple choices for a B2 level and interfaces that meet information exchange requirements and content management over the Internet using standards adopted in the world of digital learning such as Common Cartridge or SCORM. This project simply adapts the application for its use in an activities evaluation environment in which the teacher has access to the activities performed by students in a course for further evaluation. The former versión of ILLLab contained only exercises that were carried out on the mobile device so that the evaluation of these activities was not possible. The improvement comes as a Common Cartridge interface for content management, a communication interface with REST web services and a database access using Hibernate which groups a number of Java libraries for object persistence in the database.

VHDL-based system design of a cognitive sensorimotor loop (CSL) for haptic Human-Machine Interaction (HMI)

This document is a summary of the Bachelor thesis titled “VHDL-Based System Design of a Cognitive Sensorimotor Loop (CSL) for Haptic Human-Machine Interaction (HMI)” written by Pablo de Miguel Morales, Electronics Engineering student at the Universidad Politécnica de Madrid (UPM Madrid, Spain) during an Erasmus+ Exchange Program at the Beuth Hochschule für Technik (BHT Berlin, Germany). The tutor of this project is Dr. Prof. Hild. This project has been developed inside the Neurobotics Research Laboratory (NRL) in close collaboration with Benjamin Panreck, a member of the NRL, and another exchange student from the UPM Pablo Gabriel Lezcano. For a deeper comprehension of the content of the thesis, a deeper look in the document is needed as well as the viewing of the videos and the VHDL design. In the growing field of automation, a large amount of workforce is dedicated to improve, adapt and design motor controllers for a wide variety of applications. In the specific field of robotics or other machinery designed to interact with humans or their environment, new needs and technological solutions are often being discovered due to the existing, relatively unexplored new scenario it is. The project consisted of three main parts: Two VHDL-based systems and one short experiment on the haptic perception. Both VHDL systems are based on a Cognitive Sensorimotor Loop (CSL) which is a control loop designed by the NRL and mainly developed by Dr. Prof. Hild. The CSL is a control loop whose main characteristic is the fact that it does not use any external sensor to measure the speed or position of the motor but the motor itself. The motor always generates a voltage that is proportional to its angular speed so it does not need calibration. This method is energy efficient and simplifies control loops in complex systems. The first system, named CSL Stay In Touch (SIT), consists in a one DC motor system controller by a FPGA Board (Zynq ZYBO 7000) whose aim is to keep contact with any external object that touches its Sensing Platform in both directions. Apart from the main behavior, three features (Search Mode, Inertia Mode and Return Mode) have been designed to enhance the haptic interaction experience. Additionally, a VGA-Screen is also controlled by the FPGA Board for the monitoring of the whole system. This system has been completely developed, tested and improved; analyzing its timing and consumption properties. The second system, named CSL Fingerlike Mechanism (FM), consists in a fingerlike mechanical system controlled by two DC motors (Each controlling one part of the finger). The behavior is similar to the first system but in a more complex structure. This system was optional and not part of the original objectives of the thesis and it could not be properly finished and tested due to the lack of time. The haptic perception experiment was an experiment conducted to have an insight into the complexity of human haptic perception in order to implement this knowledge into technological applications. The experiment consisted in testing the capability of the subjects to recognize different objects and shapes while being blindfolded and with their ears covered. Two groups were done, one had full haptic perception while the other had to explore the environment with a plastic piece attached to their finger to create a haptic handicap. The conclusion of the thesis was that a haptic system based only on a CSL-based system is not enough to retrieve valuable information from the environment and that other sensors are needed (temperature, pressure, etc.) but that a CSL-based system is very useful to control the force applied by the system to interact with haptic sensible surfaces such as skin or tactile screens. RESUMEN. Este documento es un resumen del proyecto fin de grado titulado “VHDL-Based System Design of a Cognitive Sensorimotor Loop (CSL) for Haptic Human-Machine Interaction (HMI)” escrito por Pablo de Miguel, estudiante de Ingeniería Electrónica de Comunicaciones en la Universidad Politécnica de Madrid (UPM Madrid, España) durante un programa de intercambio Erasmus+ en la Beuth Hochschule für Technik (BHT Berlin, Alemania). El tutor de este proyecto ha sido Dr. Prof. Hild. Este proyecto se ha desarrollado dentro del Neurorobotics Research Laboratory (NRL) en estrecha colaboración con Benjamin Panreck (un miembro del NRL) y con Pablo Lezcano (Otro estudiante de intercambio de la UPM). Para una comprensión completa del trabajo es necesaria una lectura detenida de todo el documento y el visionado de los videos y análisis del diseño VHDL incluidos en el CD adjunto. En el creciente sector de la automatización, una gran cantidad de esfuerzo está dedicada a mejorar, adaptar y diseñar controladores de motor para un gran rango de aplicaciones. En el campo específico de la robótica u otra maquinaria diseñada para interactuar con los humanos o con su entorno, nuevas necesidades y soluciones tecnológicas se siguen desarrollado debido al relativamente inexplorado y nuevo escenario que supone. El proyecto consta de tres partes principales: Dos sistemas basados en VHDL y un pequeño experimento sobre la percepción háptica. Ambos sistemas VHDL están basados en el Cognitive Sesnorimotor Loop (CSL) que es un lazo de control creado por el NRL y cuyo desarrollador principal ha sido Dr. Prof. Hild. El CSL es un lazo de control cuya principal característica es la ausencia de sensores externos para medir la velocidad o la posición del motor, usando el propio motor como sensor. El motor siempre genera un voltaje proporcional a su velocidad angular de modo que no es necesaria calibración. Este método es eficiente en términos energéticos y simplifica los lazos de control en sistemas complejos. El primer sistema, llamado CSL Stay In Touch (SIT), consiste en un sistema formado por un motor DC controlado por una FPGA Board (Zynq ZYBO 7000) cuyo objetivo es mantener contacto con cualquier objeto externo que toque su plataforma sensible en ambas direcciones. Aparte del funcionamiento básico, tres modos (Search Mode, Inertia Mode y Return Mode) han sido diseñados para mejorar la interacción. Adicionalmente, se ha diseñado el control a través de la FPGA Board de una pantalla VGA para la monitorización de todo el sistema. El sistema ha sido totalmente desarrollado, testeado y mejorado; analizando su propiedades de timing y consumo energético. El segundo sistema, llamado CSL Fingerlike Mechanism (FM), consiste en un mecanismo similar a un dedo controlado por dos motores DC (Cada uno controlando una falange). Su comportamiento es similar al del primer sistema pero con una estructura más compleja. Este sistema no formaba parte de los objetivos iniciales del proyecto y por lo tanto era opcional. No pudo ser plenamente desarrollado debido a la falta de tiempo. El experimento de percepción háptica fue diseñado para profundizar en la percepción háptica humana con el objetivo de aplicar este conocimiento en aplicaciones tecnológicas. El experimento consistía en testear la capacidad de los sujetos para reconocer diferentes objetos, formas y texturas en condiciones de privación del sentido del oído y la vista. Se crearon dos grupos, en uno los sujetos tenían plena percepción háptica mientras que en el otro debían interactuar con los objetos a través de una pieza de plástico para generar un hándicap háptico. La conclusión del proyecto fue que un sistema háptico basado solo en sistemas CSL no es suficiente para recopilar información valiosa del entorno y que debe hacer uso de otros sensores (temperatura, presión, etc.). En cambio, un sistema basado en CSL es idóneo para el control de la fuerza aplicada por el sistema durante la interacción con superficies hápticas sensibles tales como la piel o pantallas táctiles.

Assessing the suitability of student interactions from Moodle data logs as predictors of cross-curricular competencies

In the past decades, online learning has transformed the educational landscape with the emergence of new ways to learn. This fact, together with recent changes in educational policy in Europe aiming to facilitate the incorporation of graduate students to the labor market, has provoked a shift on the delivery of instruction and on the role played by teachers and students, stressing the need for development of both basic and cross-curricular competencies. In parallel, the last years have witnessed the emergence of new educational disciplines that can take advantage of the information retrieved by technology-based online education in order to improve instruction, such as learning analytics. This study explores the applicability of learning analytics for prediction of development of two cross-curricular competencies – teamwork and commitment – based on the analysis of Moodle interaction data logs in a Master’s Degree program at Universidad a Distancia de Madrid (UDIMA) where the students were education professionals. The results from the study question the suitability of a general interaction-based approach and show no relation between online activity indicators and teamwork and commitment acquisition. The discussion of results includes multiple recommendations for further research on this topic.

O ESTUDANTE DA EAD (EDUCAÇÃO A DISTÂNCIA): UM ESTUDO DE PERFIL E INTERAÇÃO GERACIONAL

A aprendizagem formal e tradicional tem dado lugar a um cenário desafiador no qual educador e educando não comungam do mesmo espaço físico. A Educação a Distância (EAD), ainda é vista como uma solução que agrega cada vez mais alunos de diferentes idades que desejam uma graduação de ensino superior ou a continuidade dela. A pesquisa com o título: “O estudante da EAD (educação a distância): um estudo de perfil e interação geracional” propõe conhecer as características do perfil atual do estudante da EAD, abordando o diálogo entre as gerações no ambiente social escolar. O enfoque da pesquisa é qualitativa, exploratória e descritiva com dados que foram coletados através de entrevista com 08 alunos das gerações X e Y para assim entender se este perfil tem sido renovado com alunos mais jovens, do que a faixa etária de 25 a 45 anos. O resultado demonstra que alunos na faixa de 17 a 24 anos a cada ano aumentam 1% das matrículas. Já a faixa de 25 a 45 anos prevalece com 70% das matrículas. Portanto, este resultado revela que o perfil do aluno EAD ainda é o do jovem adulto, para adulto mais experiente, que busca a graduação com o propósito de progressão no ambiente profissional. As duas gerações citadas geração X e geração Y, mesmo em contextos históricos diferenciados de valores, crenças e comportamentos participam atualmente de uma transformação social que contempla os meios de produção do trabalho, a formação educacional e as relações sociais. O diálogo intergeracional direciona a um aprendizado compartilhado, participativo na troca de experiências mutuas. Para a geração X o jovem atual não é mais nomeado como o que precisa escutar e aprender, mas tem muito a partilhar, principalmente diante da facilidade com os meios tecnológicos. E para a geração Y, na partilha não há barreiras de idade, mas a segurança de interagir e se comunicar diante da troca de experiências

Percepção de professores sobre a influência genética e ambiental em comportamentos relevantes no processo educacional

Como as pessoas percebem as outras é relevante no processo de ensino aprendizagem e nas interações sociais como um todo. Essas percepções definem a maneira com que as pessoas reagem umas às outras. Em particular, a avaliação da percepção de professores colabora na compreensão das atitudes do professor diante dos comportamentos de seus alunos. O objetivo do presente estudo foi avaliar a percepção de professores sobre a influência genética e ambiental em comportamentos relevantes no processo educacional: personalidade, inteligência, dificuldades de aprendizagem, problemas de comportamento e doenças mentais. Para tanto, o questionário The NatureNurture Question:Teachers perceptions of how genes and the environment influence educationally relevant behavior foi adaptado à língua portuguesa do Brasil e aplicado para 501 professores de todos os níveis de ensino, do estado de São Paulo. Os resultados demonstraram que os professores atribuíram influências genéticas e ambientais em proporções aproximadamente iguais considerando todos os domínios, personalidade e dificuldades e aprendizagem. Atribuíram maior influência genética à inteligência e doenças mentais, bem como maior influência ambiental aos problemas de comportamento. Metade dos participantes afirmou ter estudado aspectos da genética em sua formação para professor. A maioria dos professores declarou que ter um aluno com dificuldade de aprendizagem geneticamente influenciada afetaria seu método de instruí-lo. Os professores percebem que genes e ambiente criação são imprescindíveis nos comportamentos de seus alunos, reconhecendo, inclusive, a interatividade dos dois fatores, informações importantes para o delineamento de ações na formação dos mesmos possíveis intervenções no âmbito educacional.

Comprehensive Validation Of A Measure Of Student School Engagement: A Pilot Study Of Middle School Students

Although it may sound reasonable that American education continues to be more effective at sending high school students to college, in a study conducted in 2009, The Council of the Great City Schools states that "slightly more than half of entering ninth grade students arrive performing below grade level in reading and math, while one in five entering ninth grade students is more than two years behind grade level...[and] 25% received support in the form of remedial literacy instruction or interventions" (Council of the Great City Schools, 2009). Students are distracted with technology (Lei & Zhao, 2005), family (Xu & Corno, 2003), medical illnesses (Nielson, 2009), learning disabilities and perhaps the most detrimental to academic success, the very lack of interest in school (Ruch, 1963). In a Johns Hopkins research study, Building a Graduation Nation - Colorado (Balfanz, 2008), warning signs were apparent years before the student dropped out of high school. The ninth grade was often referenced as a critical point that indicated success or failure to graduate high school. The research conducted by Johns Hopkins illustrates the problem: students who become disengaged from school have a much greater chance of dropping out of high school and not graduating. The first purpose of this study was to compare different measurement models of the Student School Engagement (SSE) using Factor Analysis to verify model fit with student engagement. The second purpose was to determine the extent to which the SSE instrument measures student school engagement by investigating convergent validity (via the SSE and Appleton, Christenson, Kim and Reschly's instrument and Fredricks, Blumenfeld, Friedel and Paris's instrument), discriminant validity (via Huebner's Student Life Satisfaction Survey) and criterion-related validity (via the sub-latent variables of Aspirations, Belonging and Productivity and student outcome measures such as achievement, attendance and discipline). Discriminant validity was established between the SSE and the Appleton, Christenson, Kim and Reschly's model and Fredricks, Blumenfeld, Friedel and Paris's (2005) Student Engagement Instruments (SEI). When confirming discriminant validity, the SSE's correlations were weak and statistically not significant, thus establishing discriminant validity with the SLSS. Criterion-related validity was established through structural equation modeling when the SSE was found to be a significant predictor of student outcome measures when both risk score and CSAP scores were used. The third purpose of this study was to assess the factorial invariance of the SSE instrument across gender to ensure the instrument is measuring the intended construct across different groups. Conclusively, configural, weak and metric invariances were established for the SSE as a non-significant change in chi-square indicating that all parameters including the error variances were invariant across groups of gender. Engagement is not a clearly defined psychological construct; it requires more research in order to fully comprehend its complexity. Hopefully, with parental and teacher involvement and a sense of community, student engagement can be nurtured to result in a meaningful attachment to school and academic success.

Perceptions Surrounding the Implementation of Colorado Senate Bill 10-191's New Teacher Evaluations

In 2013, many public education reform efforts in the United States of America center on testing and accountability. Recent data revealed that teachers have the single greatest in-school impact on student learning; however, the methods to assess teacher effectiveness are widely criticized for not holding teachers accountable and, consequently, are experiencing significant legislative attention. In 2010, Colorado passed Senate Bill 10-191: The Great Teachers and Leaders Act to improve student learning by revising teacher and principal evaluations, including linking them to student learning data, and eradicating tenure. Teachers, administrators, and policymakers hold critical roles in the implementation of this bill, yet little is known about how members of each group perceive their respective roles in the implementation. This explanatory sequential mixed methods study was designed to gather perception data from these three groups, through surveys and interviews. Data revealed that teachers and administrators do not have similar perceptions of many matters related to teacher evaluations, education reform, and the implementation of Senate Bill 10-191 (SB 191). The data also revealed that teachers and administrators expected they would agree on these matters. These collective findings led to multiple recommendations, such as the need for increased dialogue between teachers and administrators about their own perceptions of education reforms.

Development and psychometric testing of the clinical learning environment, supervision and nurse teacher evaluation scale (CLES+T): The Spanish version

Background: The Clinical Learning Environment, Supervision and Nurse Teacher scale is a reliable and valid instrument to evaluate the quality of the clinical learning process in international nursing education contexts. Objectives: This paper reports the development and psychometric testing of the Spanish version of the Clinical Learning Environment, Supervision and Nurse Teacher scale. Design: Cross-sectional validation study of the scale. Setting: 10 public and private hospitals in the Alicante area, and the Faculty of Health Sciences (University of Alicante, Spain). Participants: 370 student nurses on clinical placement (January 2011–March 2012). Methods: The Clinical Learning Environment, Supervision and Nurse Teacher scale was translated using the modified direct translation method. Statistical analyses were performed using PASW Statistics 18 and AMOS 18.0.0 software. A multivariate analysis was conducted in order to assess construct validity. Cronbach’s alpha coefficient was used to evaluate instrument reliability. Results: An exploratory factorial analysis identified the five dimensions from the original version, and explained 66.4% of the variance. Confirmatory factor analysis supported the factor structure of the Spanish version of the instrument. Cronbach’s alpha coefficient for the scale was .95, ranging from .80 to .97 for the subscales. Conclusion: This version of the Clinical Learning Environment, Supervision and Nurse Teacher scale instrument showed acceptable psychometric properties for use as an assessment scale in Spanish-speaking countries.
