ABSTRACT
Resumen Objetivo: Diseñar y validar un cuestionario para medir el compromiso académico en una población universitaria mexicana. Método: Se realizó un estudio de tipo instrumental donde participaron 362 estudiantes, el 70,1 % eran mujeres y el 29,9 % eran hombres, ambos grupos con una edad media de 20 años (DT = 2,7), que fueran estudiantes universitarios mexicanos. Se utilizó un Análisis Factorial Exploratorio (AFE) mediante el método de extracción mínimos cuadrados ponderados y rotación oblicua, y Análisis Factorial Confirmatorio (AFC) mediante ecuaciones estructurales. Resultados: Se obtuvo una estructura pentafactorial siendo estas involucramiento, rendimiento, reforzadores, interacción socioeducativa y resiliencia, explicando el 47,87 % de la varianza. La consistencia interna del instrumento estimada con el coeficiente de Alfa de Cronbach (α = 0,82), obteniendo parámetros de ajuste adecuados: CFI = 0,942, GFI = 0,939, AGFI = 0,920, PGFI = 0,716, RMSEA = 0,34. Discusión: El cuestionario de compromiso académico para población universitaria mexicana muestra propiedades psicométricas adecuadas, considerando factores como el involucramiento en el estudio, el rendimiento donde el alumno demuestra sus capacidades y habilidades académicas, los reforzadores que motivan al alumno en sus estudios, la valoración positiva del desempeño futuro que tendrá el alumno como profesional y la resiliencia del alumno para llevar a cabo sus tareas escolares ante situaciones estresantes
Abstract Objective: This paper aims to design and validate a questionnaire to measure Academic Engagement in a mexican university population. Method: In this cross-sectional study, 362 students participated, 70,1 % were female and 29,9 % were male, the total sample had a mean age of 20 years (SD = 2,7), who were Mexican university students. Results: The exploratory factor analysis (EFA) were carried out with weighted least squares extraction method and oblique rotation, obtained a pentafactorial structure with involvement, performance, reinforcers, socio-educative interaction and resilience, explaining 47,87 % of the variance. The internal consistency of the instrument was estimated with Cronbach's Alpha coefficient (α = 0,82), obtaining adequate adjustment parameters: CFI = 0,942, GFI = 0,939, AGFI = 0,920, PGFI = 0,716, RMSEA = 0,34. Discussion: The academic commitment questionnaire for the Mexican university population has adequate psychometric properties, considering factors such as the involvement in the study, performance where the student demonstrates his academic abilities and skills, reinforcers that motivate the student in his studies, positive valuation of the future performance that the student will have as a professional, and resilience of the student to carry out his school tasks in stressful situations.
ABSTRACT
Resumen Objetivo: Diseñar y validar el Cuestionario Percepción del profesor sobre la Deserción Universitaria (CDUp) basado en el modelo bioecológico de Bronfenbrenner. Método: En este estudio de tipo instrumental, participaron 464 profesores, el 74,1 % eran mujeres (M edad = 40,05; DE = 10,9) y el 25,9 % eran hombres (M edad = 40,09; DE = 11,23), vinculados a una universidad pública (n = 249) y privada (n = 211) de la ciudad de Tunja (Colombia). Resultados: El análisis Factorial Exploratorio (AFE) con método de extracción mínimos cuadrados y rotación promax, arrojó una estructura pentafactorial, explicando el 55,28 % de la varianza. La consistencia interna del instrumento estimada con el coeficiente de Alfa de Cronbach (α = 0,89 0,95) y el método de fiabilidad compuesta, Omega de McDonald (ω =0,890,95), reveló niveles de fiabilidad fuerte para todas las escalas: Intrapersonal, Adaptación personal, Redes de apoyo disfuncional, Interacción docente-estudiante, y Aspectos institucionales y empleabilidad. Conclusión: El CDUp es un instrumento con óptimas propiedades psicométricas, el cual permite medir la percepción que tienen los profesores sobre los factores de riesgo asociados a la deserción universitaria.
Abstract Objective: This paper aims to design and validate of the Questionnaire on Teacher Perception of University Dropout based on Bronfenbrenner's bioecological model. Method: In this instrumental study, the University Dropout Questionnaire for use by teachers (CDUp, by its acronym in Spanish) was designed and validated in a sample of 464 teachers from a public and a private university of an intermediate city in Colombia. The construction of the questionnaire was carried out based on Bronfenbrenner's bioecological model. Results: The Exploratory Factor Analysis (CFA) with least squares extraction method and promax rotation threw a five-factor theoretical structure, explaining 55,28 % of the variance. The internal consistency of the instrument, estimated with Cronbach's coefficient alpha (α = 0,890,95) and McDonald's coefficient omega (ω = 0,87 0,95), revealed strong levels of reliability for all the scales: Intrapersonal, Personal Adaptation, Dysfunctional support networks, Teacher-student interaction, and Institutional aspects and employability. Conclusion: It is concluded that the CDUp is an instrument that presents optimal psychometric properties, which allows the measurement of the perception of risk that teachers have of the students who abandon the university system.
ABSTRACT
Objective To develop a system based on wireless communication technology for psychometric questionnaire test.Methods The system was composed of one base station connected to the computer and multiple handsets.Low-power-consumption MSP430F149 and MSP430F123A were used in the base station and the handset respectively as the control unit.LSD-RF1100-A433 based on RF CC1100 was used as wireless data communication unit.By scanning each handset in sequence,the communication between the base station and the handset was realized.Then the base station could receive data which participants selected from the handsets and then sent to computer.The base station was connected to the computer through USB interface.Results Experiments showed that the system was reliable and antijamming.Conclusion The psychometric system,with the decreased weight and volume by wireless technology,can be used for large-scale psychological examination and personnel selection in some special industries.
