When Cooperation Stumbles: the effects of grades on indicators of cooperation

(English Abstract) In western societies, grades are to date the most widespread means by which achievement and performance are assessed in educational contexts. Grades are used for their capacity to provide individuals with a clear indicator of success or failure, in particular in comparison to others; in this respect, we study their impact on particular work contexts requiring cooperation. Indeed, students are often exhorted to cooperate and work in groups, while at the same time assessed with grades and focused on inter-individual comparison. However, to the best of our knowledge, no work has investigated the effects of grades on cooperation and on indicators of cooperation, a central question to be addressed given its significance for educational trends encouraging cooperative practices, and which we propose to explore in the experimental parts of this thesis. The first experimental chapter, Chapter 4, investigates the effect of grades with regards to their capacity to highlight individual visibility and at the same time social comparison. It tries to disentangle which of these facets could affect a motivated bias likely to reduce cooperation, namely individuals' preference for information confirming their own choice. In two experiments, results showed that a graded-cooperative situation increased this preference effect in comparison to other conditions where only individual visibility was manipulated, and furthermore increased individuals' perception of a competitive atmosphere. Chapter 5 investigates the effect of grades on direct cooperative inter- individual interactions, namely on group information sharing. Two experiments showed that grades hindered informational communication between individuals, leading them to withhold crucial task-information. Finally, Chapter 6 investigates the effects of grades on another indicator of group cooperation, namely inter-individual coordination. Results indicated that showcasing grades at the onset of a cooperative task necessitating inter-individual coordination decreased group performance and elicited more negative dominant behaviours amongst participants. Together these results provide evidence that grades hamper group cooperation. We conclude by discussing implications for the practice of grading in Education. ------------------------------------------------------- (Résumé en langue française) Dans la plupart des pays occidentaux, les notes sont majoritairement utilisées pour évaluer la performance et rendre compte de la réussite scolaire des individus. Dans cette perspective, elles sont non seulement un indicateur de succès ou d'échec, mais aussi de la valeur comparative des individus. Dans cette thèse nous proposons de tester l'effet des notes lorsque celles-ci sont utilisées dans des contextes bien spécifiques de coopération. En effet, si les notes et la comparaison sociale sont pratique courante, les étudiants sont souvent encouragés et amenés à coopérer en groupe. Cependant, à notre connaissance, point d'études ont testé l'effet des notes sur la coopération; études qui seraient pourtant légitimes étant donné la tendance existante en milieu éducatif à encourager les pratiques coopératives. C'est précisément ce que proposent de faire les chapitres expérimentaux de cette thèse. Le premier (Chapitre 4) teste l'effet des notes au regard de leur capacité à accentuer à la fois la visibilité et la comparaison sociale. Deux expériences investiguent l'effet des notes et tentent de démêler ce qui, de la visibilité individuelle, de la comparaison sociale ou des deux, pourrait affecter un biais motivationnel qui réduit la propension à coopérer: la propension à préférer les informations qui confirment les choix de l'individu. Les résultats montrent qu'en situation coopérative, les notes accroissent ce biais comparativement à des situations où seule la visibilité individuelle est soulignée, suggérant de plus que les notes produisent une focalisation des individus sur une comparaison sociale compétitive. Le second (Chapitre 5) teste l'effet des notes sur les interactions coopératives des individus, précisément sur le partage d'information. Deux expériences montrent que dans un contexte de travail en groupe coopératif, les notes entravent le bon partage des informations entre individus, les amenant à faire de la rétention d'information. Enfin, le troisième (Chapitre 6) investigue l'effet des notes sur un autre indicateur de coopération en groupe: la coordination interindividuelle. Les résultats montrent que les notes réduisent la coordination des individus et les mènent à avoir des comportements de dominance négative entre eux. En somme, les notes entravent la coopération et réduisent les comportements coopératifs entre individus. Enfin, nous discutons des implications pour le milieu éducatif.

Um método para avaliar a taxa de corrosão

In this paper it is proposed an indirect method to evaluate the corrosion rate of an aluminum and zinc alloy in alkaline solution by using a well-known device for collecting gases over water. The hydrogen gas formation, a corrosion product, is monitored at different time intervals and associated with the alloy mass loss. It has been suggested that the students should work in groups, which may make feasible the social interaction among them and that results discussion may be done collectively under a professor orientation. This proposal may propitiate the learning of terminology and involved concepts as well as contribute to a better understanding of corrosion phenomena that occur in their everyday life.

Social Networking Technologies: Project Launch

Students taking the 20 credit version of the course (COMP6052) will work in groups of 6 to develop and design a new social networking tool/application/website. The teams will work on their design throughout the semester, and keep a design and development blog that will act as a digital portfolio of their work. At the end of the semester they will also be asked to submit an individual reflective summary that will outline their teams objectives and progress, their part in its progress, and a critical analysis of whether or not they were successful. At the end of the course teams will be asked to pitch their ideas to an interdisciplinary Dragon's Den style panel who will expect them to not only have created something that is technical viable, but will also want to see other economic, social, legal and ethical factors taken into consideration. In this presentation we explain the structure of the group project, what is expected in the blog, and explore some potential ideas to help students understand the scope of the work required. The outcome of the group project does not have to be a fully working piece of software, instead we are looking for a well developed idea that contains enough detail to be convincing to the panel.

Prevalencia de los factores de riesgo psicosocial presentes en la población trabajadora de una entidad de salud de segundo nivel en el año 2013

Introducción: Los factores de riesgo psicosocial surgen a partir de una interacción dinámica de las cualidades humanas con el medio ambiente de trabajo, es decir, todas aquellas habilidades, necesidades, expectativas y costumbres de los trabajadores. En efecto, estas interacciones entre las condiciones del medio ambiente laboral y los factores humanos del trabajador, cuando son manejadas de manera negativa, conducen a alteraciones emocionales, problemas de comportamiento y cambios bioquímicos y neurohormonales, que a su vez pueden producir riesgos adicionales de enfermedades mentales y físicas. Objetivo: Determinar las prevalencias de los factores de riesgo psicosocial presentes en la población trabajadora de una entidad de salud de segundo nivel en el año 2013. Metodología: Se llevó a cabo un estudio de corte transversal, utilizando fuentes de datos secundarios de una Empresa de Salud del Estado de nivel II, donde se aplicó el instrumento de la batería de riesgo psicosocial, diseñada por el Ministerio de la Protección Social en asocio con la Pontificia Universidad Javeriana. Durante este período el hospital contaba con la gestión de 155 empleados, de los cuales 54 desempeñaban labores administrativas y 101 prestaban servicios asistenciales. La participación por género se distribuyó así: 104 mujeres y 51 hombres. La prevalencia de los factores de riesgo psicosocial se estimó por medio de los baremos establecidos por el Ministerio de la Protección Social para identificar el nivel de riesgo, los resultados fueron analizados desde estadísticas descriptivas y la aplicación de pruebas estadísticas en la comparación de los puntajes transformados de los dominios y dimensiones de los cuestionarios intra y extralaboral, según las características sociodemográficas y ocupacionales. Resultados: Se identificó una mayor proporción de personas con riesgo psicosocial intralaboral (45,8% riesgo muy alto), mientras que en la evaluación de los factores de riesgo extralaboral el comportamiento fue totalmente opuesto (78.1% sin riesgo), se pudo establecer que una mayor proporción de mujeres ejerce la profesión de la enfermería (71,3% asistencial) y la modalidad de contratación prevalente reportada fue a través de una cooperativa de trabajo asociado (82,2% asistenciales). Se determinó que existen diferencias en la percepción de los factores psicosociales tanto intra como extralaborales en los grupos con diferentes características sociodemográficas y ocupacionales. Conclusión: La investigación evidenció el impacto negativo de los factores de riesgo intralaboral sobre los trabajadores de la E.S.E, condición que afectó la percepción de la vida laboral, la productividad y el nivel de satisfacción de los trabajadores, por lo que se destaca la pertinencia de implementar actividades de intervención y prevención a corto plazo en el marco de un programa de vigilancia epidemiológica.

Farmer experience of pluralistic agricultural extension, Malawi

Purpose: Malawi’s current extension policy supports pluralism and advocates responsiveness to farmer demand. We investigate whether smallholder farmers’ experience supports the assumption that access to multiple service providers leads to extension and advisory services that respond to the needs of farmers. Design/methodology/approach: Within a case study approach, two villages were purposively selected for in-depth qualitative analysis of available services and farmers’ experiences. Focus group discussions were held separately with male and female farmers in each village, followed by semi-structured interviews with 12 key informants selected through snowball sampling. Transcripts were analysed by themes and summaries of themes were made from cross case analysis. Findings: Farmers appreciate having access to a variety of sources of technical advice and enterprise specific technology. However, most service providers continue to dominate and dictate what they will offer. Market access remains a challenge, as providers still emphasize pushing a particular technology to increase farm productivity rather than addressing farmers’ expressed needs. Although farmers work in groups, providers do not seek to strengthen these to enable active interaction and to link them to input and produce markets. This limits farmers’ capacity to continue with innovations after service providers pull out. Poor coordination between providers limits exploitation of potential synergies amongst actors. Practical implications: Services providers can adapt their approach to engage farmers in discussion of their needs and work collaboratively to address them. At a system level, institutions that have a coordination function can play a more dynamic role in brokering interaction between providers and farmers to ensure coverage and responsiveness. Originality/value: The study provides a new farmer perspective on the implementation of extension reforms.

Mecanismos sócio-genéticos da representação social de trabalho docente por grupos de licenciandos de física e de química da Universidade Federal do Rio Grande do Norte

This research aims to understand the social representations Teaching Work in groups of undergraduate students of Physics and Chemistry of the Federal University of Rio Grande do Norte. For this, the proposal was based on the three theoretical and methodological consensus Carvalho (2012) in the explanation of socio-genetic mechanisms constituents of dynamic consensus that has functionality to your organization. It Was used to achieve this goal, the theoretical-epistemological Serge Moscovici (1978, 2003), Jodelet (2011), Wagner (1998,( 2011) and Carvalho (2012). The corpus analyzed results from a qualitative and quantitative research, developed in three stages. The first two (2) questionnaires to fifty (50) of each undergraduate course, a questionnaire and another profile for collection of free associations concerning motes inductors "Give Lesson," "Student" and "Teacher". The second step in the procedure Multiple Classifications, Roazzi (1995), aimed for another thirty (30) undergraduate students for each course, as well as Document Analysis of Educational Projects Curriculum courses in Physics and Chemistry. The data analysis of the first stage focused on descriptive statistics and frequency and average order of the words associated with motes inductors. The results from the Multiple Classification Procedure submitted to multidimensional analysis (MSA multidimensional scalogram analysis) and SSA (Similarity Structure Analysis), were interpreted by the theoretical and methodological proposal of the three consensus, supported by analysis of the rhetorical nature of justifications classifications and categorizations of words, boosted in times of application of Procedure Multiple Classification. The data revealed that the groups surveyed were the same Social Representation with specific dynamic consensual. Thinking Teaching Work for these groups it is considered in three dimensions: the BE-DO-HAVE of teaching. In the group of Physics consensus was clear semantic, which expressed a dynamic in which the interpretations of "Teaching Work" peacefully coexist on perceptions of two concepts: An identity around the "BE" "Teacher" or "BE" "Educator" and the other, how they think about professional development. The type of group consensus Chemistry pointed to a consensual logic hierarchical order in which the gradual between the elements of BE-DO-HAVE attested conflicts and disagreements about the perceptual object "Teaching Work", around what value most, whether they are the attributes of personal or professional-technical dimension of teaching, in the course of professional development. The thesis to explain the mechanisms of socio-genetic Representation Social Teaching Work by theoretical and methodological proposal was confirmed

Educação ambiental para crianças no ambiente urbano: uma proposta de pesquisa-ação

Este estudo de Educação Ambiental envolveu crianças de 6 a 11 anos de idade de um bairro de classe popular - Cohab I - na cidade de Botucatu. O objetivo principal do projeto foi contribuir para desenvolver nas crianças atitudes de cuidado com o meio onde vivem, proporcionando oportunidades de aquisição de conhecimentos, valores, atitudes e interesse ativo para protegê- lo e melhorá-lo. Trata-se de um estudo desenvolvido com os referenciais da metodologia da pesquisa-ação participativa, que considera fundamental a participação dos sujeitos envolvidos tanto no processo de produção de conhecimentos quanto na tomada de decisões. Através de conversas, atividades e brincadeiras variadas, as crianças construíram conhecimentos sobre o bairro, percebendo como podem e devem exercer ali um importante papel social de melhoria da qualidade de vida no ambiente em que vivem. As crianças foram incentivadas a participar e levar essa preocupação aos adultos.

Análise experimental da resistência à corrosão e da velocidade de corrosão: uma proposta pedagógica

In this work it is proposed the use of a chemical activity, in which a corrosion process occurs, aiming to provide to the student relationship among the learning concepts and corrosion phenomena that occur everyday. It is suggested that the experiment development is based on Vygotsky theory, so that students work in groups, which may facilitate social interaction among students and results discussion among groups under professor guidance. This proposal can provide the involved concepts learning, as well as student training such as a critical and reflexive individual.

Grupo de estudo/discussão como estratégia formadora de autonomia docente em professores de física

This work is intended to promote a reflection about the forms of work in groups for continuous training of teachers. Based on the hypothesis that the groups of study / discussion of specific topics in physics can have very effects significant and recommended by the literature, we based on the propositions of the educator José Contreras Domingo about autonomy of teachers and we does a report of an experience with group of continuing education in which they succeeded in developing the characteristics of autonomy of teachers in a job with physics teachers who participate in a group of study / discussion of topics of Modern and Contemporary Physics. In this way presents arguments relating the autonomy of teachers with the teacher continuing education and presents the report of a group of training teachers of physics who works along these lines.

An Uphill Battle: Incorporating cooperative learning using a largely individualized curriculum

In this action research study of my classroom of 8th grade mathematics, I investigated if cooperative learning could be an effective teaching method with the Saxon curriculum. Saxon curriculum is largely individualized in that most lessons could be completed without much group interaction. I discovered that cooperative learning was very successful with the curriculum as long as it was structured. Ninety-five percent of the students in the study preferred to work in groups, and I observed mathematical communication grow with most of the students. As a result of this research, I plan to continue to incorporate cooperative learning into my mathematics classroom. I will use cooperative learning with all of my mathematics classes, even the ones that do not use the Saxon curriculum. I believe in the power of working together.

The Effects Improving Student Discourse Has on Learning Mathematics

In this action research study of my 8th grade mathematics classroom, I investigated how improving student discourse affects learning mathematics. I conducted this study because I wanted to give students more opportunities to develop and share their ideas with their peers as well as with me. My idea was to create a learning environment that encouraged students to voice their opinions. In order to do so, I needed to reassure and model with my students that they were in a classroom where it was safe to take risks, and they should feel comfortable sharing their ideas. By facilitating activities for students to complete in groups, asking students to prepare work to share with the class, and offering more opportunities for students to work with each other on discovering and exploring math skills being presented, I set the tone for abundant student discourse to take place in the mathematics classroom. I discovered that students became more comfortable with math skills the more opportunities they had to discuss the ideas in various settings. I also found that as the study went on, students discovered the importance of being able to share their mathematical ideas and valued the ability to verbalize their thoughts with others. As a result of this study, I plan to continue offering many opportunities for students to work in groups as well as to share their ideas with the class.

How to Use Cooperative Learning for Assessing Students’ Emotional Competences: A Practical Example at the Tertiary Level

Cooperative learning allows students acquisition of competences that are essential for the labour market such as leadership, critical thinking, communication, and so on. For this reason, different cooperative activities were designed in a language subject in English Studies so that students could work in groups and acquire those competences. This article describes some such activities and the emotional competences that students acquire with them. Moreover, a survey was conducted in order to establish students’ opinions about the main competences they acquired with the activities designed and their opinion about a cooperative methodology. Students’ answers were positive and they were aware of what they had learned.
