Educational materials (textbooks in particular) are key for improving learning, especially in precarious school contexts. In the case of Peru, from 1990 on, the State has experimented with different models of educational material provision. In spite of their differences, they share a lack of impact in improving students’learning outcomes. The authors state that the problem stems from the absence of teacher training in how to use educational materials, which should be a core element of any model of educational material provision.

El presente trabajo de investigación, tipificado como correlacional explicativo, reposa en el análisis del cuerpo teórico que intenta dar pruebas, inicialmente, de los resultados de las pruebas de rendimiento académico. Es decir, analiza las perspectivas teóricas: oportunidades de aprendizaje y educabilidad, que tienen a la teoría de sistemas como el respaldo último, para explicar un aspecto, sin duda fundamental, de la educación del Perú: los niveles de resultados de los estudiantes en pruebas de rendimiento nacional e internacional. Sin embargo, dada la naturaleza de la economía peruana y las expectativas de la población, la tasa de escolaridad -según ámbitos nacional, urbano y rural- es asumida como variable a explicar. Previo al marco teórico, esbozamos en la introducción todos aquellos factores que condicionan la nueva realidad que, desde fines de la década de los oc...

Given the wave of violence in the state of Guerrero, Mexico, it is important to know the effects of this phenomenon on the behavior and academic performance of adolescent students. Likewise, it is necessary to inquire the causes in which the most common violent behaviors manifest themselves, as well as to postulate local and institutional alternatives that improve school care for this highly vulnerable population in the face of organized crime. Having said this, the purpose of this work is to investigate the constitutive elements that generate bullying and disruption of learning in the students of Technical Secondary No. 185 Hermenegildo Galeana in the city of Chilpancingo. For this, qualitative ethnographic work was carried out in order to explain in a dense and detailed way the power relations between students, as well as the conditions in which the teaching-learning process develops. ...

The incorporation of Game-Based Learning has been promoted as a cornerstone of pedagogical innovation, yet important gaps persist regarding how teachers, especially in rural areas, understand and appropriate this strategy under conditions of scarcity. Guided by this overarching question, the study sought to understand, both theoretically and practically, how primary-school teachers at IE 70022-Collana (Puno - Peru) appropriate the strategy, using a qualitative phenomenological–interpretive approach. Five in-depth interviews were conducted with teachers who had more than twenty-five years of service, and a thematic analysis supported by qualitative coding was applied. Findings reveal: 1) a strong conviction that play is a prerequisite for meaningful learning and a cultural bond; 2) structural constraints (scarce materials, lack of time and weak institutional support) that compel creativ...
