Assessment criteria, satisfactory (1)

Student: • knows objects and phenomena related to the topic • partially knows how to relate objects and phenomena related to the topic to technology and everyday applications • knows the quantities related to the objects and phenomena of the subject area, the related units and the laws between the quantities only in familiar, exemplary situations. • has a basic idea of the phenomena related to the subject area of insufficient qualitative level • Recognizes the basic phenomena of physics appearing in problems related to the topic, the whole is partly unstructured and incomplete. • can describe on a qualitative level some of the basic principles of solving problems related to the topic and makes his solutions as copies of previously studied examples. • recognize, with support or based on a previous example, the quantities related to the problems and their preservation or change • the selection of the laws needed to solve the problems is based on support or ready-made example models. Self-directed selection of models is uncertain and partly random. • knows how to solve computational problems in situations that are, for example, familiar • can sometimes state the solutions of computational problems with suitable accuracy of presentation • the student has challenges justifying the choices he has made orally or in writing • there are challenges in assessing the correctness and reliability of computational solutions. • Works in the measurement related to the topic as part of a group
