Digital relief models deliver a valuable information about the morphology of a particular area. They are useful in structural geomorphology analysis. However, their correct generation requires knowledge of geostatistic methods, including cross-validation. This article presents the importance of cross-validation, using the example of the Grodziec area (Silesian Upland, southern Poland). The choice of the test area was determined by its geomorphology – high altitude differences (140 meters maximum) and the co-occurence of landforms of different rank, genesis and size. This area includes some towering hills – monadnocks, which are Middle-Triassic cuesta remainders. These forms clearly dominate in the surrounding area incised by river valleys. Besides the large forms sculptured by erosion and denudation processes, there are also anthropogenic landforms – stone pits – of much smaller size. We asked the question whether and to what extent they will be “visible” on digital relief models depending on the variogram model setup. Two digital relief models were generated (one with a deliberately incorrect and one with the correct variogram setup) and verified using the cross-validation method. The results of this experiment show that correct digital model carries only slight overestimation of mean squared standardized error while the incorrect model shows substantial underestimation of sampling points values. The correct model is more vivid – it clearly shows most of the relief details while the DTM (digital terrain model) generated by the incorrect setup is misrepresented and blurred. This indicates that conclusions based on incorrect relief models may be subject to high errors.

The subject of this article is information and communication technologies (ICT) in geographic education according to the new core curriculum from 2017 (Rozporządzenie Ministra Edukacji Narodowej …, 2017). For the purposes of analysis of the possibilities of using ICT in the school, five models have been developed regarding the inclusion of ICT in the teaching program. From the simplest models, which involve searching for didactic materials for online geography lessons on the Internet by the teacher, to the most advanced ones – related to the presence of ICT throughout education process. Each subsequent model is characterized by a greater involvement of teachers and students in the use of ICT in school practice. The analysis of the new core curriculum for geography shows that in both primary and post-primary school, selected content should be implemented using information and communication technologies. The examples of free ICT tools presented in the study (“Worldometers”, “Geographic Games, Play and Explore the World”, “Kineticcity”, “Ventusky”, “LearningApps” and “Scholaris”) are an excellent teaching aids. They help the student to better understand different, sometimes complex geographic issues.

Przedmiotem niniejszego artykułu są technologie informacyjno-komunikacyjne (TIK) w kształceniu geograficznym według nowej podstawy programowej z 2017 roku (Rozporządzenie Ministra Edukacji Narodowej…, 2017). Na potrzeby analizy możliwości wykorzystania technologii informacyjno-komunikacyjnych w szkole, opracowano pięć modeli dotyczących włączania TIK do praktyki szkolnej. Od najprostszych modeli, które polegają na wyszukiwaniu materiałów dydaktycznych na lekcje geografii w Internecie przez nauczyciela, po najbardziej zaawansowane – związane z obecnością TIK podczas całego procesu kształcenia. Każdy kolejny model charakteryzuje się coraz większym zaangażowaniem nauczycieli i uczniów w wykorzystywaniu TIK w praktyce szkolnej. Z analizy nowej podstawy programowej do geografii wynika, że zarówno w szkole podstawowej, jak i ponadpodstawowej wybrane treści powinny być realizowane z wykorzystaniem technologii informacyjno-komunikacyjnych. Przedstawione w opracowaniu przykłady darmowych narzędzi TIK („Worldometers”, „Gry geograficzne. Graj i poznawaj świat”, „Kineticcity”, „Ventusky”, „LearningApps” oraz „Scholaris”) stanowią doskonałe środki dydaktyczne. Ułatwiają uczniowi lepiej zrozumieć różne, czasami złożone zagadnienia geograficzne.
