Deposition of cesium and cobalt sorbed on zeolite in matrices of blast furnace slag

Cs-137 and Co-60 were sorbed from model solutions and waste water on chemically treated granular zeolite. The zeolite was incorporated into cement slurries based on blast furnace slag (BFS). The compressive and bending strength were measured after different times of hydration. The leaching tests were performed in water, base and acid solutions. The leachability was more pronounced only for samples in acidic solutions

The importance of didactic toys in kindergarten educational process

The aim of this study is to identify preschool children’s strategies in choice and play with didactic toys. The research was based on participatory observation of children with the set of original didactic toys. In total, 77 children aged 2 to 6 years from four different kindergartens were observed, with children always in small groups. The data obtained in the form of video recordings and field notes was then transcribed and analyzed using qualitative methods. The results point out the teacher’s influence, usually determined what the toy serves or what task have to accomplished. We also point out the possible conditionality of the child’s interest in the toy. Findings highlights the child’s strategy in the play, especially the modification of the toy that arises just when the child has the opportunity to independently explore the toys. The importance is to support the didactic thinking of kindergarten’s teachers including pre-service teachers. © 2020, Springer Nature Switzerland AG
