Introduction
One of my passions in life is designing effective learning processes, creating a partnership space in education, looking for ways to motivate students to take initiative and proactive attitude in the learning process. And supporting teachers in their teaching and students in learning methods of effective learning. Also: Taxonomic revisions of African and American orchids (Orchidaceae) basing on morphological and molecular evidence.

Description
  • The Center for Innovative Education is a space where we build learning ecosystems based on modern teaching methodology. It is a laboratory for the agile search for solutions supporting the process of effective learning based on scientific knowledge. The idea of creating a new unit is the beginning of the process of realizing the dream of introducing a change in the area of teaching methodology in Poland. Our goal is to support teachers in reflective design of an active learning environment.

Polystachya is a large, pantropical orchid genus of 200 species, most of which occur as epiphytes in sub-saharan Africa. The three-lobed labellum of most Polystachya species possesses a fleshy callus and various types of trichomes and papillae. In this paper, we present the results of micromorphological studies on the labellum of 20 species, repres...

Three plastid regions, matK, rpl32-trnL and rpl16 intron and the ITS1-5.8S-ITS2 nuclear ribosomal DNA were used to demonstrate a phylogenetic placement of the genus Hederorkis (Orchidaceae) for the first time. The taxonomic position of this genus has been unclear thus far. The phylogenetic and morphological relations of Hederorkis to the most close...
