Preschool teachers' view on learning in preschool in Sweden and Denmark
- 2014
-
In: European Early Childhood Education Research Journal. - 1350-293X .- 1752-1807. ; 22:5, s. 590-603
-
Journal article (peer-reviewed)abstract
- The aim of this study was to examine how preschool teachers in Sweden and Denmark perceive children's learning in preschool. The study aimed to answer the following questions: What is 'learning'? How do children learn? What are the best conditions for children's learning? What is the role of participation in children's learning? The results show that from the teacher's perspectives, children's learning is connected to children's social interaction and development in which the children's initiatives are crucial. Learning, to a great extent, results from children's active involvement. There are many similarities between how Danish and Swedish preschool teachers think of learning and participation. This supports earlier assumption about the coherence of Nordic preschool beliefs which unites education and care.

Preschool teachers' views on children's learning : an international perspective

In: Early Child Development and Care. - : Informa UK Limited. - 0300-4430 .- 1476-8275. ; 185:5, s. 824-847

Journal article (peer-reviewed)abstract
- This comparative study investigated the perspectives of preschool teachers in Australia, Denmark, Estonia, German, Greece and Sweden about learning and participation in preschool. A structured survey questionnaire investigated four main questions: What situations can be characterised as learning? What activities are important for learning? What are the best conditions for children's learning? How do preschool teachers understand participation in relation to children's learning in preschool? Results suggest that play, interactions with other children and adults, the provision of different activities and teacher support are important for children's learning. While similarities were noted, results indicate some disparity between countries and a further in-depth interview-style study is recommended to provide a deeper understanding of teachers' perspectives and practices around children's learning.

An a posteriori error estimate for symplectic Euler approximation of optimal control problems
- 2014
-
Other publication (other academic/artistic)abstract
- This work focuses on numerical solutions of optimal control problems. A time discretization error representation is derived for the approximation of the associated value function. It concerns Symplectic Euler solutions of the Hamiltonian system connected with the optimal control problem. The error representation has a leading order term consisting of an error density that is computable from Symplectic Euler solutions. Under an assumption of the pathwise convergence of the approximate dual function as the maximum time step goes to zero, we prove that the remainder is of higher order than the leading error density part in the error representation. With the error representation, it is possible to perform adaptive time stepping. We apply an adaptive algorithm originally developed for ordinary differential equations. The performance is illustrated by numerical tests.

Book chapter (pop. science, debate, etc.)abstract
- The biblical foundation, church history and design of the work with poverty in today's society is drawn by Elinn Leo Sandberg in chapter 11. How should poverty, people who are poor, be treated in a welfare society and how should the church act?
