The effectiveness of "Learning by doing" as a strategy that uses the elaboration of didactic material done by the learners

Tesis (Pedagogía en Inglés)Nowadays, the instruction of vocabulary on the acquisition and learning of English as a second language is important and it has been recognized as a relevant aspect by academics and theoreticians of the area. The aim of this study is to prove, through a concrete and an experimental form, the effectiveness of the constructivist strategy that uses the elaboration of didactic material as an improvement manner for the acquisition and learning of explicit vocabulary that, at the same time, may be meaningful to the pupils. The “Learning by Doing” strategy has been built under the perspective of the theory of constructivism, which has been adapted to be applied on two different educational establishments; both subsidized. The first school is located in El Belloto and the second school institution located in Villa Alemana. Accordingly, the thesis study was carried out on 5 different courses with a final average of 132 students. This inquiry has a quantitative nature with a quasi – experimental design that has as a sample a paired – dependent kind, which took into account the control subunits and the experimental subunits from each EFL (English as a Foreign Language) classroom where the strategy previously mentioned was conducted. As described on the previous paragraph, the results were analyzed using a mathematical – statistical type of measurement denominated “T – Test” table. These demonstrated that the constructivist strategy namely “Learning by Doing” improve the learning of explicit vocabulary on those grades belonging to the primary education.

Esto ha sido reconocido como un aspecto relevante por académicos y teóricos del área. El objetivo de esta investigación es probar a través de una forma concreta y experimental la efectividad de una estrategia que usa la elaboración de material didáctico como manera de mejorar la adquisición y el aprendizaje del vocabulario explícito, y que éste a su vez sea significativo para el alumno. La estrategia “Learning by Doing” ha sido construida bajo la perspectiva de la teoría del constructivismo, la cual ha sido adaptada para ser aplicada en dos establecimientos educacionales diferentes, ambos subvencionados. El primero situado en El Belloto y el segundo ubicado en Villa Alemana. Por consiguiente, esta investigación se realizó en 5 cursos diferentes con un promedio final de 132 alumnos. Esta investigación tiene una naturaleza cuantitativa con un diseño cuasi – experimental y tiene como muestra un tipo dependiente y pareado, la cual tomó en consideración las subunidades controles y las subunidades experimentales de cada clase “EFL” en donde la estrategia previamente mencionada fue llevada a cabo. Según lo descrito en el párrafo anterior, los resultados fueron analizados usando un tipo de medición matemático – estadística denominada tabla “T – Test”. Éstos demostraron que la estrategia constructivista nombrada “Learning by Doing” mejoró el aprendizaje de vocabulario explícito en aquellos cursos pertenecientes a la educación general básica. Sin embargo, el curso perteneciente a la enseñanza media no mostró ninguna señal de mejoramiento cuando la estrategia que usa la elaboración de material didáctico llegó a su fin

Validation of a performance model on entrepreneurship based on self-efficacy, personal goal orientation and environment goal orientation using Structural Equation Modeling

Master's thesis in International hotel and tourism managementThree are the main contributions that I pretend to provide through this research. First, I will combine four theoretical constructs that, to my knowledge, have not been worked through this way before. I mean that this research is attempting to validate and estimate the existing relationships between Self-efficacy, Perceived Personal Goal Orientation, Perceived Environment Goal Orientation and Perceived Personal Performance. There is much evidence in the literature that has explored the connections between self-efficacy and the goal theory as I will show later. Those works used to focus on explaining how setting goals improves performance in a varied set of fields. Goals are “what an individual is trying to accomplish; it is the object or aim of an action“ (E. Locke, Saari, L., Shaw, K., and Latham, G., 1981). There is some agreement that setting goals increase performance in two ways: first, there is a direct relation between setting goals and performance, and, second, goals and performance relationship is mediated by self-efficacy: greater performance increase self-perceptions of competence, as a consequence, individuals would set even higher goals (Edwin A. Locke & Latham, 1990). However, for this project, my focus is on the analysis of goal orientation. For the sake of a better understanding of this project, I have to explain -before going deeper- what is the difference between “setting goals” and “goal orientation”. The former refers to the individual’s actions oriented to establish –formally or informally- future goals related to upcoming events. For example, when a university student is getting ready for final exams might set (as a goals) to obtain A or B grades only. The “goal orientation”, which is the central concept involved in this project, refers to something a bit different: if individuals perceive themselves or their environment as performance oriented (PGO): focus on comparisons to others (i.e., I want the best grade of my class) - or as task oriented (TGO): focus on comparisons to one’s self (i.e., I want to improve my last score in this class).

Proceso constructivo pavimento en piedra pegada municipio de Sutatausa, Cundinamarca

Trabajo de investigaciónEl municipio de Sutatausa se encuentra en la provincia del valle de Ubaté, cuenta con cerca de 5 km de vías urbanas y por ser un pueblo turístico y colonial por excelencia, sus calles se han venido construyendo de piedra pegada, algo diferente a lo tradicional, han pasado varias administraciones municipales y cada una de ellas aporta un porcentaje para llegar al 100% de calles empedradas, sin embargo no se cuenta con documento técnico donde se indique el correcto procedimiento para la construcción de este tipo de pavimento.INTRODUCCIÓN 1.

Conflicto trabajo-familia y percepción de autoeficacia parental en padres con hijos con discapacidad de escuelas especiales de Talca

132 p.La presente investigación tiene como objetivo determinar la relación entre los tipos de interacción familia-trabajo con el nivel de autoeficacia parental percibido por una muestra de padres con hijos con discapacidad, considerando las características de los tipos de discapacidad como un factor negativo que genera diferencias significativas, tanto en los niveles de autoeficacia como en los tipos de interacción, que pueden llevar a un conflicto entre la familia y el trabajo. La muestra de este estudio compone un total de 133 apoderados pertenecientes a 7 escuelas especiales de la ciudad de Talca. Los datos fueron recolectados aplicando la Escala de Evaluación Parental o EPP (Farkas, 2008) para la variable de autoeficacia parental y la versión española 71 del cuestionario SWING (Geurts, Taris, Kompier, Dikkers, Van Hooff & Kinnunen, 2005) para la evaluación de interacción trabajo-familia. Los resultados obtenidos demuestran que no existe una asociación entre los tipos de interacción trabajo-familia y la autoeficacia parental para esta población, en este sentido se diferencia de los resultados de otras investigaciones con población chilena (Riquelme y Rojas, 2010; Jiménez, Concha y Zúñiga, 2012) teniendo como explicación plausible la diferencia en el nivel educacional entre las muestras de las investigaciones. La interacción trabajo-familia es preponderantemente positiva y nace a partir de la familia hacia el trabajo (x=10,55; σ=4,19), la percepción autoeficacia parental para los padres con hijos con discapacidad resulta ser baja (x=48,95; σ=15,19) como era esperable por razones de estrés parental. No se observan diferencias significativas entre los tipos de discapacidad para ninguna de las dos variables, concluyendo que la discapacidad se establece como una condición única para todos los apoderados y es la familia la que cambia, se reorganiza para mantener un buen funcionamiento familiar./Palabras clave: Discapacidad, Autoeficacia Parental, Conflicto Trabajo-Familia, Equilibrio Trabajo-Familia, Trabajo-Familia./ABSTRACT: This research aims to determine the relationship between the types of work-family interaction with the level of parental self-efficacy perceived by a sample of parents with children with disabilities, considering the characteristics of the types of disability as a negative factor that generates significant differences, both self-efficacy levels and the types of interaction, which can lead to conflict between family and work.The study sample comprised a total ofInteracción 133 agents belonging to 7 special schools in the city of Talca. Data were collected using Parental Rating Scale or EPP (Farkas, 2008) for parental self-efficacy variable and the Spanish version of the questionnaire 71 SWING (Geurts, Taris, Kompier, Dikkers, Van Hooff & Kinnunen, 2005) for evaluation work-family interaction. The results show that there is an association between the types of work-family interaction and parental self-efficacy for this population, in this respect it differs from the results of other research with Chilean population (Riquelme and Rojas, 2010; Jimenez, Concha y Zúñiga, 2012) having as plausible difference in educational attainment between the research samples. The work-family interaction is positive and arises predominantly from family to work (x = 10.55, σ = 4.19), parental self-efficacy perception for parents with children with disabilities is to be low (x = 48 , 95, σ = 15.19) as expected for reasons of parental stress. No significant differences between the types of disability for any of the two variables, concluding that disability is established as a unique condition for all parents and family that changes, reorganizes to maintain a good family functioning.

Modelo de demanda para bovinos carne en el Centro Occidente de México, 1996-2017

El objetivo fue evaluar el impacto de los factores que determinan la demanda de carne bovina en canal en la región Centro-Occidente de México durante 1997-2017, con elasticidades. Se utilizó un modelo de regresión múltiple exponencial doble logaritmo. La variable dependiente fue la demanda de carne de bovino y las regresoras el precio real al consumidor de carne bovina, precio real al consumidor de carne de cerdo, ingreso real per cápita y población. En la región Centro-Occidente de México, la demanda respondió inversa e inelásticamente al precio del producto (-0.39), directa e inelástica al precio de la carne de cerdo (0.15), directa e inelástica al ingreso (0.35), directa y elástica a la población (0.11). Se concluye que el ingreso del consumidor y el precio de la carne bovina generaron mayor respuesta en el comportamiento regional de la demanda de esa carne

List of Clustered Permutations in Secondary Memory

Similarity search is a difficult problem and various indexing schemas have been defined to process similarity queries efficiently in many applications, including multimedia databases and other repositories handling complex objects. Metric indices support efficient similarity searches, but most of them are designed for main memory. Thus, they can handle only small datasets, suffering serious performance degradations when the objects reside on disk.Most real-life database applications require indices able to work on secondary memory. Among a plethora of indices, the List of Clustered Permutations (LCP) has shown to be competitive in main memory, since groups the permutations and establishes a criterion to discard whole clusters according the permutation of their centers. We introduce a secondary-memory variant of the LCP, which maintains the low number of distance evaluations when comparing the permutations themselves, and also needs a low number of I/O operations at construction and searching.XII Workshop Bases de Datos y Minería de Datos (WBDDM)Red de Universidades con Carreras en Informática (RedUNCI
