Construcción, reconstrucción y consolidación del desaparecido Grupo Escolar “Francisco Giner de los Ríos” de Alicante (España)

La demolición del Grupo Escolar “Francisco Giner de los Ríos” supuso una pérdida incuestionable para la ciudad de Alicante (España), desapareciendo uno de los más relevantes ejemplos racionalistas, símbolo de modernidad y del desarrollo que en materia de enseñanza significó en la ciudad el “Plan de Construcción de Escuelas y Ordenación Escolar” de 1931. Con el fin de contribuir a subsanar el vacío documental que antecedió su demolición, el presente artículo muestra los resultados del estudio de las fases determinantes de la historia del edificio: proyecto (1933), construcción (1934-1935), reconstrucción y consolidación (1943-1944). Se concluyen las causas que originaron la ruina del inmueble, el alcance y magnitud de los daños y las avanzadas técnicas empleadas en su recuperación, prestando especial interés a las intervenciones de cimentación y consolidación del terreno, pilotajes e inyecciones de cemento, prácticas de relevancia internacional en el periodo de posguerra en España y Segunda Guerra Mundial.

Coordination of aproximations in secondary school students’ understanding of limit concept

The aim of this research is to characterize the coordination of the processes of approximation related to the understanding of the limit of a function. We analyze the answers of 64 post-secondary school students to 7 problems considering the dynamic and metric conception of limit of a function. Results indicate that the metric understanding of the limit in terms of inequality supports that the student is capable of coordinating the approximations in the domain and in the range when lateral approximations coincide. However, the student is not capable of this coordination when lateral approximations do not coincide. This indicates that the metric understanding of the limit begins with the previous construction of the dynamic conception in case of coincidence of the lateral approximations in the range.

Primeras políticas de vivienda en España y su influencia en la evolución de la tipología residencial: el caso de Benalúa (1883-1956)

El estudio del proceso de adaptación tipológica de las arquitecturas residenciales del barrio de Benalúa, una de las áreas consolidadas más singulares de la ciudad de Alicante (España), constituye un ejemplo clave para entender el alcance que tuvieron las primeras políticas de vivienda aplicadas en ese país, con anterioridad a la redacción de los Planes Generales que, en el transcurso del siglo XX, fueron ordenando las ciudades españolas y que en el caso de Alicante coincidió con la aprobación de la primera Ley del Suelo estatal (1956). De su análisis se obtienen las conclusiones que identifican los procedimientos que, por cambios sociales, políticos, de normativa o presión del mercado inmobiliario, condicionaron la evolución de la vivienda durante siete décadas, huellas que en la actualidad vienen desapareciendo a un ritmo vertiginoso, constatando el grado de intervención del Estado y de los municipios, así como su influencia y responsabilidad en la determinación de los tipos edificatorios.

Reducing visual deficits caused by refractive errors in school and preschool children: results of a pilot school program in the Andean region of Apurimac, Peru

Background: Refractive error is defined as the inability of the eye to bring parallel rays of light into focus on the retina, resulting in nearsightedness (myopia), farsightedness (Hyperopia) or astigmatism. Uncorrected refractive error in children is associated with increased morbidity and reduced educational opportunities. Vision screening (VS) is a method for identifying children with visual impairment or eye conditions likely to lead to visual impairment. Objective: To analyze the utility of vision screening conducted by teachers and to contribute to a better estimation of the prevalence of childhood refractive errors in Apurimac, Peru. Design: A pilot vision screening program in preschool (Group I) and elementary school children (Group II) was conducted with the participation of 26 trained teachers. Children whose visual acuity was<6/9 [20/30] (Group I) and≤6/9 (Group II) in one or both eyes, measured with the Snellen Tumbling E chart at 6 m, were referred for a comprehensive eye exam. Specificity and positive predictive value to detect refractive error were calculated against clinical examination. Program assessment with participants was conducted to evaluate outcomes and procedures. Results: A total sample of 364 children aged 3–11 were screened; 45 children were examined at Centro Oftalmológico Monseñor Enrique Pelach (COMEP) Eye Hospital. Prevalence of refractive error was 6.2% (Group I) and 6.9% (Group II); specificity of teacher vision screening was 95.8% and 93.0%, while positive predictive value was 59.1% and 47.8% for each group, respectively. Aspects highlighted to improve the program included extending training, increasing parental involvement, and helping referred children to attend the hospital. Conclusion: Prevalence of refractive error in children is significant in the region. Vision screening performed by trained teachers is a valid intervention for early detection of refractive error, including screening of preschool children. Program sustainability and improvements in education and quality of life resulting from childhood vision screening require further research.

Goal Orientation Profiles and Self-Concept of Secondary School Students

The objective of this study is to identify possible combinations of multiple goals that lead to different goal orientation profiles and to determine whether there are significant group differences in self-concept dimensions. The Achievement Goals Tendencies Questionnaire (AGTQ) and the Self-Description Questionnaire-II (SDQ-II) were administered to a sample of 2,022 students of Compulsory Secondary education, ranging in age from 12 to 16 years (M = 13.81, SD = 1.35). Cluster analysis identified four profiles of motivational goals: a group of students with a generalized high motivation profile, a group of students with generalized low motivation profile, a group of students with a predominance of learning goals and achievement goals, and a last group of students with a predominance of achievement goals and social reinforcement goals. Results reveal statistically significant differences among the profiles obtained regarding self-concept dimensions.

Workshops in “Construction of Structures I”: A new teaching methodology in the Building Engineering Degree

Both the current economic situation in the construction sector and the continuous normative changes in the building area imply the use of new methodologies to enhance students’ competences in the degree of Building Engineer. The aim of this paper is to present, analyse and discuss the development of constructive workshops as a new teaching methodology used in the subject of Construction of Structures I at the University of Alicante to complement the constructive and technical knowledge acquired by our students and to enhance their communicative and representation skills essential for their professional practice in the future. The used methodology is based on the development of three-dimensional construction details (in groups of 3 or 4 students) to be shown in two A1-pannels exposed in the corridors of the Polytechnic School. Thus, students’ work approaches constructive problems in a global way by discussing simultaneously with teachers and other groups about the most suitable solution on each case. This contribution has multiperspective results and improves criticism of students in different areas, encouraging new learning strategies and active participation. What is more, on-line information and web applications have been used to prepare and organize this kind of workshops, allowing students to use new technologies as a complementary learning methodology. In conclusion, the use of these new workshops in the Degree of Building Engineer stimulates an interactive class versus a traditional lecture where the participative groups´ attitude and the development of oral presentations dissolve the traditional boundaries regarding public communication skills of the students in the Degree.

El sueño de un barrio y la problemática del ensanche: la obra inconclusa de Benalúa de Alicante (1883-1896)

El presente artículo describe la construcción de Benalúa, según proyecto del arquitecto José Guardiola Picó (1883), una de las áreas más singulares de la ciudad de Alicante -España-. Se realiza una exposición cronológica desde su concepción, documentando las tramitaciones legales que conllevaron su aprobación, hasta el cese en sus funciones de la Sociedad Anónima Los Diez Amigos, promotora y constructora del barrio (1896), sin finalizar con éxito el proyecto emprendido. Del estudio se concluyen tanto los aspectos más relevantes que caracterizaron el desarrollo de las obras del barrio como las causas que propiciaron el abandono de la Sociedad, siendo éstas exclusivamente económicas, con especial interés en la problemática que llegó a generar el proyecto y ejecución del Ensanche de Alicante.

Body Percussion and Team Building through the BAPNE Method

BAPNE Method is a method based on cognitive stimulation integrating music and movement through body percussion. The aim of this research is to explore its whole potential as a tool to build teams. Team building is a philosophy for work design, and since over two decades ago, it defends that obtaining a high performance and organizing efficiency is more useful to perceive employees as interdependent members in a team of work than individuals ones. From this viewpoint, this research advocates that BAPNE Method’s body percussion practice will have an impact on this vision of team work directly. For its own characteristics, body percussion stimulates ways of contact in movement, which ease social ties and, especially, promote group cohesion. Through social, body and, affective dimension; BAPNE Method is capable of developing a shared vision and a single aim, to stimulate team work identity and an atmosphere of trust; and finally, to improve individual communication and satisfaction levels in group tasks.
