A propositional logic is defined which in addition to propositional language contains a list of probabilistic operators of the form P ≥s (with the intended meaning ‘‘the probability is at least s’’). The axioms and rules syntactically determine that ranges of probabilities in the corresponding models are always finite. The completeness theorem is proved. It is shown that completeness cannot be generalized to arbitrary theories.

The partnership of educators and parents of children with developmental disabilities is important for early intervention, as an integrated and interdisciplinary system of professional services intended for children of an early age with developmental disabilities and children who may be late in starting school due to inadequacy: nutrition, chronic diseases, biological and environmental factors. The aim of the research is to examine the assessments of educators and parents about the involvement of families of children with developmental disabilities in kindergarten activities. (...) It started from the general assumption that there is a difference in the assessments of educators and parents about family involvement in kindergarten activities. The research conducted in October 2022 included 167 educators and 167 parents in the area of Kikinda and Sombor (Serbia), who assessed family participation in kindergarten activities (PP) for 167 children aged five to seven. The quality of cooperation was examined with the Subtest Parents’ involvement in kindergarten activities. This subtest forms part of the Parental Involvement Questionnaire (Fantuzzo et al, 2000) adapted for this research (a = 0,921). The research results show that there is a significant difference in the assessments of educators and parents in the area of family involvement in kindergarten activities. It was concluded that there is a need for planning guidelines and implementation of procedures that would enable parents to participate in kindergarten activities. The application of the new Program Basis in the context of cooperation between preschool institutions and parents would contribute to the improvement of project planning of learning and teaching in pedagogical practice. This would help parents better understand project-based learning and the importance of participating in kindergarten activities. (shrink)
