Teacher training for the effective implementation of Information and Communication Technologies (ICT) in education has become a key aspect of educational research. In this regard, the lack of appropriate models to support teachers in their professional development is evident. An investigation has been conducted on the most effective ways in which elementary school teachers acquire their digital competencies based on the contributions of 23 experts. Using Delphi methodology with two iterations, expert knowledge about the problem was probed to learn how it is developed and refined. Adopting the theoretical lens of Learning Ecologies, the results provide a contrast on which components support effective professional learning with respect to ICT integration, laying the groundwork for new methods and approaches to professional development.

La investigación tuvo como objetivo determinar las propiedades psicométricas de la escala de dependencia a los videojuegos en adolescentes de Instituciones Educativas de Lurigancho - Chosica en el año 2023. La muestra fue de 1021 adolescentes con edades de 12 a 17 años. El instrumento utilizado fue la Escala de Dependencia a los videojuegos de Choliz y Marco (2011). El instrumento fue valorado por jueces expertos y además de utilizó el coeficiente de razón de validez de Lawshe, con valores entre 0.80 a 1. En el análisis factorial exploratorio, se obtuvo el total de 25 ítems con cuatro dimensiones. El análisis confirmatorio, arrojo un (χ²/gl) de 2.72, un (SRMS) de 0.0247, un (RMSEA) de 0.0411, un (CFI) 0.975, un (TLI) de 0.970. La confiabilidad, revelo un valor de 0.920 a través del Alfa de Cronbach y un valor de 0.921 a través de Omega de Mc Donald. El valor de confiabilida...
