In this article, which is part of a broader investigation based on the study of the educational and socio-occupational re-engagement processes of young people in vulnerable situations, the curricular design of the vocational training programs (VTP) is described. Further, the curricular practices developed in the classrooms of these programs are analyzed, based, above all, on how the contents are selected, as well as the methodological approaches for their development. The research methodology that was followed responds to the conduct of multiple case studies with the integration of quantitative and qualitative processes. The data collection instruments used for this purpose were questionnaires, interviews, and discussion groups. The conclusions reveal the selection of contents that are relevant, interesting, and close to the reality of the students. The development of these contents is displayed through varied methodological strategies and diverse activities that enhance the students’ involvement and the practical sense of their learning.

It is known that the COVID-19 pandemic led to learning losses among students both domestically and internationally. Therefore, situational and casual factors were examined to discover and understand them so that learning loss could be reduced or recovered from. This research aimed to: (a) study learning loss situation; and (b) develop and examine the causal model of learning loss among lower secondary school students affected by the pandemic. The sample included 650 Grade 7-9 students selected by multi-stage random sampling. The data was collected using a self-developing questionnaire as a research instrument. The data was analyzed using descriptive statistics, independent samples t-test, ANOVA, and structural equation modeling (SEM) through the LISREL program. The findings were: (a) Lower secondary school students had an average academic achievement learning loss at the moderate level with the highest mean of learning loss in mathematics (M=3.012, SD=1.074), and an average learning characteristics learning loss at the medium level (M=2.824, SD=0.842). Several situational factors had a different effect depending on the school size with a statistical significance of .05.; and (b) the causal model showed the learning loss of grade 7-9 students was consistent with the empirical data (χ2=46.885, df=34, p= .069, GFI=0.991, AGFI=0.964, CFI=0.999, RMSEA=0.024, SRMR=0.014).
