The University’s strategy aims to increase the numbers of International Students studying here, and this brings particular challenges for the teaching staff. Do you sometimes wonder if your international students are able to fully engage with their studies? Have you been in a situation where the international students in your class seem very quiet and reluctant to engage in group discussion? Have you found a higher proportion of international students seemed to struggle with their assignments? This guide highlights some of the issues facing international students studying in the UK and it provides tips for teaching staff to use in order to maximise the internal students engagement in their studies. In addition the guide provides references to further reading and resources both within the University and externally. You can find this guide on your blackboard site: TTLLP-GPG: Good practice guide for supporting international students. The production of the guide was funded by the Transition to Living & Learning Project.

En el año 2002, la Secretaría de Educación de Bogotá estipuló la Resolución 2101 que tenía por objeto asegurar el ciclo de la educación completo en los colegios públicos. El propósito de este trabajo es evaluar el impacto de los mecanismos seguidos a la aplicación de esta política sobre la tasa de deserción escolar. Las escuelas tenían tres mecanismos diferentes para alcanzar el objetivo de la presente resolución: expandir los grados escolares ofertados, integrarse con otros colegios de la zona, o ambos. Para ello, utilizo variables instrumentales para resolver el sesgo causado por el hecho de que los colegios que siguen determinada estrategia eran los que tenían altas tasas de deserción inicialmente. Usando datos sobre las características institucionales y las características socio-demográficas de la población cerca del colegio, evalúo el impacto de estos tres mecanismos sobre las tasas de deserción escolar. Los resultados sugieren que las instituciones que aumentaron los grados experimentan un aumento en el número de estudiantes que abandonan el colegio en 12.1 puntos porcentuales, mientras que las instituciones que complementaron este mecanismo con la integración de un colegio próximo pre existente mostraron una reducción en la tasa de deserción escolar de 9.8 puntos porcentuales.

Revisión didáctica subyacente a la impartición de lenguas extranjeras en el contexto sociopedagógico de las aulas, con el fin de que los alumnos puedan adquirir las destrezas comunicativas lingüísticas necesarias a nivel oral y escrito. Aplicado a seis grupos de primero de BUP de 35 alumnos cada grupo, del Instituto Tomás de Iriarte de Santa Cruz de Tenerife. La metodología llevada a cabo ha sido a través de un enfoque natural, siendo indispensable para ello, actitud favorable, orden creciente de dificultad, creación de reglas formales, mensajes significativos para el discente, etc. Los instrumentos de obtención de la información se llevaron a cabo a través de cuestionarios personales (intereses, nivel social, etc.) y observaciones de conocimientos y actitudes hacia la segunda lengua. La experiencia ha sido válida tanto para la formación profesional de los profesores como para el aprovechamiento académico de los alumnos. Valoración favorable del enfoque natural y necesidad de investigar en el área de adquisición de segundas lenguas.
Evaluation of strategic knowledge of students through authentic tasks of writingin science classroom

The difficulties at evaluating strategic knowledge have been connected to the use of deconxetualized tests that, at the end, do not involve the use of this knowledge. For this reason, an interest in developing authentic writing tasks that offer advantages for these kinds of evaluation have arisen. Throughout this research, authentic writing tasks were developed in a natural sciences class, with the purpose of evaluating the students' strategic knowledge. Different instruments were used to collect data, e.g. Interviews, questionnaires, a self-inform, as well as three samples of writing by the students, with the objective of analyzing the changes that occurred between one and the others, as well as to determine the decisions that students made in order to complete the assigned tasks successfully. An authentic writing task gives great opportunities to evaluate strategic knowledge. These tasks lead students to arrange their knowledge about the topic in hand, organize and adapt it to fit the objectives and the audience, also, it allows them to control and adjust their decisions on the task. This last stage became the perfect opportunity to take notes on the knowledge and regulation of cognitive processes that the students brought into play, as well as to evaluating their understanding of writing and the demands given on the different discursive genres. As a result, the students showed different degrees of strategic knowledge in the task. The students who showed a better strategic knowledge trust in their structural abilities know about discursive genres and have a good performance in basic linguistic abilities. The students who showed weak strategic knowledge distrust their writing skills, seem extremely worried about organizing the content of their texts, fail when checking their writings, and overlook or are unaware of the basic requirements of the discursive genre they are asked to exemplify. It appears that the previous knowledge and experiences at writing the students have been exposed to may affect the strategic knowledge shown when writing in this subject.

I look for classroom peer effects for psychoactive substance consumption among Colombian high school students and attempt to identify channels that rationalize for these effects. To do so, I use data for Colombian schools from 2011. I identify peer effects using household consumption behavior to instrument average classroom consumption. I find that an increase of 10% in the proportion of classroom users of alcohol, cannabis, and cocaine increases the probability of students to use alcohol, cannabis, and cocaine in 3.14%, 4.29%, and 2.38% respectively. I find no significant effect on cigarette smoking for the full sample but after exploring heterogeneous effects I find suggestive evidence that the effect is positive in some grades. I find some evidence that indicate that peer effects on alcohol, cannabis, and cocaine consumption operate through risk perception and easiness of access to psychoactive substances, meaning that the increase of likelihood of consumption could be explained because it is easier to access to drugs for students that interact with consumers or because a decrease in the risk students perceive of consuming these substances. Finally, through the use of a SUR and a 3SLS estimator I find strong correlations between smoking cigarettes and consuming cannabis (55 %), and cocaine (60 %).

This paper studies oligopolistic competition in education markets when schools can be private and public and when the quality of education depends on ìpeer groupî e§ects. In the Örst stage of our game schools set their quality and in the second stage they Öx their tuition fees. We examine how the (subgame perfect Nash) equilibrium allocation (qualities, tuition fees and welfare) is a§ected by the presence of public schools and by their relative position in the quality range. When there are no peer group e§ects, e¢ ciency is achieved when (at least) all but one school are public. In particular in the two school case, the impact of a public school is spectacular as we go from a setting of extreme di§erentiation to an e¢ cient allocation. However, in the three school case, a single public school will lower welfare compared to the private equilibrium. We then introduce a peer group e§ect which, for any given school is determined by its student with the highest ability. These PGE do have a signiÖcant impact on the results. The mixed equilibrium is now never e¢ cient. However, welfare continues to be improved if all but one school are public. Overall, the presence of PGE reduces the e§ectiveness of public schools as regulatory tool in an otherwise private education sector.

We investigate the effect of education Conditional Cash Transfer programs (CCTs) on teenage pregnancy. Our main concern is with how the size and sign of the effect may depend on the design of the program. Using a simple model we show that an education CCT that conditions renewal on school performance reduces teenage pregnancy; the program can increase teenage pregnancy if it does not condition on school performance. Then, using an original data base, we estimate the causal impact on teenage pregnancy of two education CCTs implemented in Bogot´a (Subsidio Educativo, SE, and Familias en Acci´on, FA); both programs differ particularly on whether school success is a condition for renewal or not. We show that SE has negative average effect on teenage pregnancy while FA has a null average effect. We also find that SE has either null or no effect for adolescents in all age and grade groups while FA has positive, null or negative effects for adolescents in different age and grade groups. Since SE conditions renewal on school success and FA does not, we can argue that the empirical results are consistent with the predictions of our model and that conditioning renewal of the subsidy on school success crucially determines the effect of the subsidy on teenage pregnancy

We investigate whether and how the type of unemployment benefit institution affects productivity. We designed a field experiment to compare workers’ productivity under a welfare system, where the unemployed receive an unconditional monetary transfer, with their productivity under a workfare system, where the transfer is received conditional on the unemployed spending some time on ancillary activities. First, we find that having an unemployment benefit institution, regardless of whether it makes transfers conditional or unconditional, increases workers’ productivity. Second, we find that productivity is higher under Welfare than under Workfare. Becoming unemployed under Welfare comes at the psychological cost of a drop in self-esteem, presumably due to the shame or stigma associated with receiving an unconditional unemployment benefit. We document the empirical relevance of precisely this channel. The differences we observe in productivity suggest that this psychological cost acts as an extra nonmonetary incentive for workers under Welfare to put a higher effort in their work.
