We learn from practice
Tichá, Marie ; Hošpesová, A.
The teachers should systematically cultivate their competences. In submitted contribution we deal with improvement of teacherďs subject-didactical and pedagogical/psychological competences. Our considerations are based on samples of teachin experiments and following collective reflection of teachers and researchers.

Segeth, Karel ; Šolín, P.
According to the general framework of the method of lines, we split the numerical solution of the nonstationary compressible Euler equations in 1D, 2D and 3D into the three following steps: First, the system of PDE´s is semidiscretized in space. Second the smoothness and Lipschitz continuity of the right-hand-side (RHS) of the arising system of ordinary equations (ODE´s) is analyzed and its solvability is discussed. Third, classical ODE packages ( we use ODEPACK and DDASPK ) are applied to the system of ODE´s.

This paper studies a restricted class of randomized on-line non-preemptive algorithms for scheduling in multiprocessor systems. In this class each task is specified by its processing time and scheduled to a processor with the smallest or $h$th biggest load for a fixed $h$. The competitive ratio is the maximum of the ratios of the expected makespan and the optimal makespan over all.

We consider the following scheduling problem. The input is a set of jobs with equal processing times, where each job is specified by its release time and deadline. The goal is to determine a single-processor, non-preemptive schedule of these jobs that maximizes the number of completed jobs. In the online version, each job arrives at its release time.

Collective reflections in mathematics lessons
Hošpesová, A. ; Tichá, Marie
The contribution is based on analysis of several video-tapes of mathematics lessons. It is shown how the group of elementary teachers understands and evaluates their competences in the course of preparation, realisation and assessmentseveral teaching experiments. Improvement of their subject-didactical competence is outlined.
