Exploratory learning activities in the physics classroom: contrasting cases versus a rich dataset.

In exploratory learning, students engage in an exploration activity on a new topic prior to instruction. This inversion of the traditional tell-then-practice order has been shown to benefit learning outcomes, especially conceptual knowledge and preparation for future learning, but not always. In three studies, the current work examines whether the type of exploration activity impacts learning mechanisms and outcomes, on the topic of gravitational field in undergraduate physics classrooms. Activities using either contrasting cases (CC) or a rich dataset (RD) are compared in two instructional orders, explore-first (EF) and instruct-first (IF). Learning outcomes measured procedural knowledge, conceptual knowledge, and performance using a dynamic preparation for future learning (PFL) assessment that included a learning resource within the posttest. In addition, the current studies investigated process level measurements of interest and enjoyment, knowledge gap awareness, and cognitive load. Study 1 revealed that students in the EF-CC condition had better conceptual knowledge and PFL scores than students in the IF-CC condition. Study 2 investigated learning outcomes following an RD activity in EF and IF orders in two separate physics classrooms (algebra-based physics for pre-medicine majors, and calculus-based for engineering majors). Procedural and conceptual knowledge overall was improved by the EF order, but only in the calculus-based course; PFL showed no differences. Study 3 compared learning outcomes from the two activities directly in a 2 (order: EF, IF) × 2 (activity: CC, RD) study design. Overall, the CC activity resulted in better student learning than the RD activity. However, an effect of instructional order was not found, potentially due to a methodological error. Across the three studies, interest and enjoyment did not differ by condition and did not predict learning outcomes. Knowledge gap awareness was higher for students in the EF order than the IF order for both activities, and negatively predicted learning outcomes. Cognitive load was negatively correlated with conceptual and PFL learning outcomes, but only in Study 3. Overall, results indicate that the type of activity could moderate learning outcomes, with any instructional order. More work is needed to investigate the boundary conditions impacting the benefit of exploratory learning, including activity type, amount of guidance during the activity, and the type of instruction

On social regulation in Nannotrigona (Scaptotrigona) postica latreille, with special reference to male production cycles (Hym., Apidae, Meliponinae)

A produção de machos em Nannotrigona (Scaptotrigona) postica e alguns aspectos correlacionados foram investigados e os resultados mostram que os fatores extrínsecos como temperatura e precipitação, através da sua importância na determinação das floradas e subsequente aumento na disponibilidade de mel e pólen, não são fatores determinantes imediatos da alta produtividade da colônia e da produção de machos, como consequência. Os dados também sugerem uma ausência de inibição da rainha no desenvolvimento ovariano das operárias e que a produção de machos ocorre independentemente da idade fisiológica da rainha. É possível que muitos outros fatores intrínsecos como alta densidade populacional da colônia (provavelmente conseqüente de condições favoráveis de estoque de pólen e mel) sejam mais importantes na determinação da produção de machos, uma vez que colônias que apresentam uma baixa densidade populacional não produzem machos, embora os ovários das operárias estejam sempre desenvolvidos. Além disso, a produção de machos parece estar ligada à oviposição das operárias devido à relação existente entre ocorrência de machos e células de cria contendo mais do que um ovo por célula, numa mesma colônia

CALIDAD DE DOCENTES DE EDUCACI 3N PRE-ESCOLAR Y PRIMARIA: PROGRAMA DE CAPACITACI 3N EN LA UNIDAD EDUCATIVA "MACARIO Y\uc9PEZ", EN PROBLEMAS DE CONDUCTA Y APRENDIZAJE, COMUNIDAD CRUZ BLANCA. BARQUISIMETO ESTADO LARA.

La realidad social venezolana demuestra que el problema de conflictos en las instituciones escolares se incrementa importantemente, lo cual puede tener relaci\uf3n con el bajo rendimiento escolar de los j\uf3venes y de otros logros que pueda existir por parte de la instituci\uf3n educativa. Para conocer de esta realidad se realiz\uf3 en primer lugar, un diagn\uf3stico de la situaci\uf3n actual relacionado con este problema, espec\uedficamente docentes, directora y miembros de la comunidad. De ah\ued, se elabor\uf3 un proyecto de Capacitaci\uf3n a los/as docentes de la Unidad Educativa "Macario Y\ue9pez" dentro de los lineamientos requeridos por la Coordinaci\uf3n de Extensi\uf3n del Decanato de Ciencias de la Salud acreditado con el c\uf3digo EU-CS-022-2012, con estrategias en el manejo de los problemas de comportamiento y de aprendizaje con el prop\uf3sito de contribuir a la calidad de maestros de educaci\uf3n primaria y secundaria de la instituci\uf3n, optimizando la convivencia escolar en general. Gracias a la participaci\uf3n de los docentes fue posible dise\uf1ar una serie de m\uf3dulos tem\ue1ticos enfocados en el desarrollo profesional en prevenci\uf3n de problemas de comportamiento y aprendizaje y la aplicaci\uf3n de actividades pr\ue1cticas para complementar su labor docentes, con la ideas de formar una Red de Consejeros en la escuela que puedan atender y asesorar este tipo de problemas de convivencia. La evaluaci\uf3n realizada en los docentes nos conduce a continuar con la ejecuci\uf3n de este tipo de programa de formaci\uf3n a futuro, en la escuela o en otras instituciones educativas, considerando atender los siguientes aspectos: a) Estimular a los docentes a continuar su formaci\uf3n y participar para que mejoren su disposici\uf3n a ense\uf1ar b) Promover la creaci\uf3n de redes de maestros y escuelas, c) Apoyar la evaluaci\uf3n de impacto de estas actividad en las pr\ue1cticas de ense\uf1anza y en el aprendizaje de los estudiantes, d) Difundir el proyecto en la direcci\uf3n general sectorial de Educaci\uf3n, para que se sensibilice la necesidad de capacitar a los docentes en el \ue1rea de problemas de conducta y aprendizaje, en vista de la ausencia de principios b\ue1sicos de comportamiento lo que genera serios problemas escolares en las instituciones p\ufablicas. Finalmente, un docente formado en la atenci\uf3n y la prevenci\uf3n de los problemas de convivencia logra el desarrollo integral del educando, contribuyendo a crear un ambiente productivo que estimula al alcance de las metas escolares e institucionales. ABSTRACT QUALITY PRE-SCHOOL TEACHERS AND PRIMARY SCHOOL: TRAINING PROGRAM EDUCATION UNIT "MACARIO YEPEZ" IN BEHAVIORAL AND LEARNING PROBLEMS, "CRUZ BLANCA" COMMUNITY. BARQUISIMETO LARA STATE. The Venezuelan social reality shows that the problem of conflicts in the schools significantly increases, which may be related to poor school performance of youth and other achievements that may exist by the educational institution. For this reality was made first, a diagnosis of the current situation related to this problem, specifically teachers, principal and community members. From there, he developed a draft Training of / as teachers of the Education Unit "Macario Yepez" within the guidelines required by the Extension Coordination Dean of Health Sciences accredited with the code EU-CS-022-2012 with strategies in the management of behavioral problems and learning with the aim of contributing to the quality of teachers in primary and secondary education in the institution, optimizing school life in general. Thanks to the participation of teachers was possible to design a series of thematic modules focused on professional development for the prevention of behavior and learning problems and the implementation of practical activities to supplement their educational work with the ideas form a Network of Advisers that they can attend school and advise these problems of coexistence. The teacher assessment in us to continue the execution of such future training program, school or other educational institutions, considering addressing the following aspects: a) Encourage teachers to continue their education and participate to improve their readiness to teach b) Promote networking of teachers and schools, c) support the assessment of impact of these activities on teaching practices and student learning, d) Disseminate the project in the direction Education sector generally, to be sensitized to the need to train teachers in the area of behavioral and learning problems, in view of the absence of basic principles of behavior that raises serious school problems in public institutions. Finally, a teacher trained in the care and prevention of the problems of coexistence manages the development of the student, helping to create a productive environment that stimulates the scope of school and institutional goals. <br

Complex Hydrological System Inflow Prediction using Artificial Neural Network

Artificial neural networks have been successfully used to model and predict water flows for a few decades. Different network types have proven to work better in different cases and additional tools and algorithms have been implemented to improve those neural models. However, some problems still occur in certain cases. This paper deals with the limitation of complex hydrological system inflow prediction using artificial neural network and inflow time series. This limitation is called the prediction lag and it disables the model from giving accurate predictions. To eliminate the prediction lag and to extend prediction horizon an alternative input variable named forecasted precipitation frequency is proposed in addition to antecedent inflow time-series. Simulation results prove the efficiency of the proposed solution that enables time series neural network model for 7th-day inflow prediction. This represents important information in operational planning of the hydrological system, used for short-term optimization of the system, e.g. optimization of the hydroelectric power plant operation
