Co-assessment in higher education: The perception of first-year students

Es imprescindible implicar al alumnado en la evaluación para fomentar su aprendizaje. La modalidad participativa más desconocida es la coevaluación o evaluación compartida. Teniendo en consideración el uso polisémico del concepto coevaluación en español, en este estudio se entiende como aquella evaluación negociada entre docentes y estudiantes donde la responsabilidad es compartida y en la que es imprescindible el diálogo. En la literatura específica se destaca que esta modalidad favorece el aprendizaje autónomo y la autorregulación. Para contrastar con la realidad las consecuencias de la evaluación compartida se ha desarrollado una experiencia que implicó a 192 estudiantes universitarios de primer curso durante tres años académicos. Tras su implantación, se realizó un estudio descriptivo mediante un cuestionario on-line para analizar la potencialidad para el aprendizaje, comprobar el grado de satisfacción del alumnado y conocer los aspectos positivos y negativos que detectaron los estudiantes. En los resultados se puede comprobar la elevada satisfacción del alumnado con la coevaluación. Los participantes consideran que la mayor potencialidad para el aprendizaje proviene de la importancia de la retroalimentación que se ofrece, ya que permite ser más conscientes de los errores y aprender de ellos. Igualmente, otros elementos positivos detectados fueron la colaboración y la comunicación entre docente y estudiantes, así como la formación sobre el proceso de evaluación. Es imprescindible continuar con la implantación e indagación de evaluaciones basadas en el diálogo y en compartir significados en el contexto universitario, que permitan a los estudiantes mejorar sus aprendizajes y a los docentes optimizar y flexibilizar sus estrategias de enseñanzaParticipative assessment strategies such as self-assessment, peer assessment and co-assessment enhance student learning. Co-assessment is the least known participative strategy. Considering the polysemous use of the word co-assessment in the Spanish literature in this study the concept is defined and understood as a teacher-student negotiated assessment where the responsibility of assessment is shared and dialogue is key. Co-assessment promotes self-regulated and autonomous learning according to the specific literature. To analyse the consequences of co-assessment a three-year study involving 192 first-year students was implemented. An on-line survey was applied to analyse the learning potentialities of co-assessment, students’ satisfaction with the experience and the positive and negative aspects perceived. The results show high student satisfaction. Most participants consider a learning potentiality the importance of the feedback provided when implementing co-assessment since it allows them to find out their mistakes and learn from them. Likewise, other positive aspects mentioned include the collaboration and communication established among teachers and students and an increasing of assessment literacy. The authors of the study believe it is important to continue with the implementation and research of dialogue-based assessment practices and in sharing meanings in Higher Education, which might allow students to enhance their learning and teachers to optimise and increase the adaptability of their teaching and learning strategie

Análisis de las calificaciones compartidas en la modalidad participativa de la evaluación colaborativa entre docente y estudiantes

Current trends in educational assessment in different branches of higher education share the common goal of uniting learning with assessment. Most approaches and theoretical and practical developments in this field revolve around four main factors: feedback, democratization, alignment and relevance. This paper proposes the use of co-assessment as a means of ensuring dialogue-based, democratic and fairer evaluations. With co-assessment, the responsibility is shared by the teacher and the students, who negotiate and agree on the appraisal of student tasks and, in this paper, also on the awarded mark. The aim of this study is to analyse the relationship between a series of jointly agreed marks, following the co-assessment of four tasks, and the marks that the teachers and students would each have individually awarded. Two teachers and 100 students participated in the study, which follows a correlational design and analyses significant statistical differences. The results show a strong correlation between the jointly agreed marks and those assigned individually by the teacher, even though statistically significant differences were found between them. Conversely, no statistically significant differences were identified between the joint marks and the marks assigned individually by the students. These results call for reflection on the real possibility of adapting shared grading methods to students in university frameworks, where the repercussions of awarded marks go far beyond formative goals.Dentro de la variedad existente en las tendencias actuales sobre la evaluación de estudiantes, se encuentra el propósito común de relacionar evaluación y aprendizaje. La retroalimentación, la democratización, la coherencia y la relevancia son cuatro tópicos aglutinadores sobre los que giran la mayoría de los planteamientos y avances teóricos y prácticos en este ámbito. Como forma concreta de cristalizar una evaluación dialógica, democrática y justa, se propone la modalidad participativa de la evaluación colaborativa en la que docentes y estudiantes se reparten la responsabilidad, negociando y consensuando de forma conjunta el valor de las tareas y en nuestro caso, también la calificación final. El propósito de este estudio, que ha involucrado a un total de 100 alumnos y 2 docentes, es precisamente la comprobación del grado de relación existente entre las calificaciones compartidas de 4 tareas universitarias con las que habrían aportado en solitario el docente y el grupo de estudiantes. Se ha seguido un diseño de investigación correlacional y se ha comprobado la existencia de diferencias significativas. Los resultados muestran la estrecha correlación entre las calificaciones compartidas y las calificaciones del docente, aunque se han hallado diferencias estadísticamente significativas entre estas. Por otro lado, no se han encontrado diferencias entre las calificaciones compartidas y las calificaciones de los estudiantes. Las repercusiones de estos resultados, hacen reflexionar, entre otras cuestiones, sobre la posibilidad real de ajustar dichas calificaciones abiertas a la participación de los estudiantes en contextos universitarios donde las repercusiones sobrepasan de largo el ámbito únicamente formativo

Assessing the influence of legal constraints on the integration of renewable energy technologies in polygeneration systems for buildings

Hybrid polygeneration systems offer a great opportunity to meet growing energy demands with cost efficiency and environmental benefits. The identification of the optimal solution (configuration and operational strategy) is strongly affected by the relationship between the system and its surroundings. Previous studies have analyzed the influence of boundary conditions on the synthesis of polygeneration systems for buildings. However, local regulations are often disregarded or oversimplified in those studies. Therefore, this paper aims to evaluate the influence of legal conditions on the integration of renewable energy technologies in polygeneration systems for buildings. A comprehensive synthesis model is developed, including different types of legal conditions, such as power exchange modalities, subsidies/surcharges on energy prices and investment costs, and total ban on fossil fuels. Then, the model is applied to the case study of a Brazilian hospital. The current Brazilian net metering scheme is implemented. Results show that natural gas cogeneration is an attractive solution to cover the hospital's energy demands with or without the possibility of selling/exporting electricity. Also, the Brazilian net metering scheme, by itself, is not enough to ensure renewable energy deployment. An in-depth discussion about the conditions that would promote renewable energy integration is reported and recommendations are made on how current policies can be improved, including the need to explicitly address renewable technologies, the application of minimum renewable fractions, and the role of renewable heat/cooling. While the case study considers the specific circumstances in Brazil, it provides insights that can be extended to other countries or applications
