<p style="text-align: justify;">This work has two objectives. The first is to describe a program to strengthen socio-cognitive abilities in initial education children (called PHSC), which is focused on training teachers on its implementation in the classroom. The second objective is to examine the effectiveness of the program when it is applied in schools with different socio-cultural contexts. It involved a total of 257 initial-level students attending two pre-primary schools in the province of Mendoza. One school was in an urban area of a more stable social environment, and the other in a socially-vulnerable area.  The program was administered by teachers who had been trained for it. Pre- and post-assessments were conducted using socio-cognitive tests on the students. The teachers responded to the Executive Functioning Scale for initial education children before and after implementation of the PHSC program, and parents responded to an on-line survey to find out whether they had noticed any improvements or positive changes after the application of the program. The results suggest the possibility that this program, implemented by teachers, could improve the socio-cognitive abilities in children of both of the different social contexts, as well as being a driver to create conditions of equal opportunities and generate learning benefits in all their students.</p>

<p style="text-align: justify;">The objective of this study was to design an instrument to evaluate parental involvement in the education of their children, and, subsequently, to investigate the content validity of that instrument. The questions on the questionnaire have been written according to the dimensions that shape the construct of parental participation: parenting, learning supervision, communication, parental networks, and relationships with the community. Further, for the study of content validity, expert judgment has been used, and the Aiken V coefficient has been estimated. The results indicate a wide degree of agreement among the judges, showing evidence of content validity regarding the criteria of clarity, relevance, and sufficiency of the questions with Aiken V values that ranged between 0.73 and 1, with confidence intervals of 99 %. It was concluded that the instrument can be used successfully in the evaluation of parental involvement in education.</p>
