Zkvalitňování kultury vyučování matematice cestou kolektivní reflexe
Hošpesová, A. ; Tichá, Marie
Cultivation of teachersďself-reflection and systematic conduction of collective reflection can change character and promote quality of personaly oriented education. Therefore we aim at creation of supporting conditions for realizing these activies. In this contribution we show how a choosen group of primary shool teachers perceived and evaluated their competencies in the course.

Teacherďs competences and action research in mathematics teaching
Tichá, Marie ; Hošpesová, A. ; Macháčková, J.
In the contribution meaningful role of systematic carrying out of self-reflection and common reflection in the professional development of teachers. Reflection and action research are shown as key items in the development of subject-didactic and pedagogical competences of teachers and in improvement of quality of mathematics education and teaching. The base of contribution is a video recording of realisation of teaching experiments designed by teachers themselves.

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.

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.

Interaction of sperm surface proteins in the reproduction process
Jonáková, Věra ; Kraus, Marek ; Maňásková, Pavla ; Liberda, J. ; Tichá, M.
Mammalian fertilization includes highly regulated biochemical interactions between complementary molecules located on the surfaces of both gametes as well as those present in the natural environment of the gametes. Boar seminal plasma proteins AQN, AWN spermadhesins and DQH protein that are bound to the sperm at ejaculation play important role in the reproduction process. Binding of sperm to epithelial cells, recognition of gametes and binding of sperm to glycoprotein of zona pellucida are mediated by protein-saccharide interaction, lektin-type interaction. Another type of interaction (protein-protein) participates in the formation of aggregated forms, which seem to be the natural functional forms of seminal plasma proteins. Protein aggregates form the sperm coating layers and their re-modeling in the female reproductive tract is imporatnt for the sperm capacitation and for the primary binding of spermto the ovum.

The maximum flow in a network
Tichá, Michaela ; Pelikán, Jan (advisor) ; Čížek, Ondřej (referee)
The work describes how to find the maximum flow in a network. It has two parts - theoretic and programmatic. The theoretic part desribes founded maximum flow algorithms. The programmatic part contains program for searching the maximum flow in a network.
