Course abstract

This part of the study course provides the students with practical skills when working in the laboratory, which are based on knowledge obtained in the first part of this study course. The students strengthen their knowledge on the taxonomic diversity of the kingdom animals, on the body plans of animals representing different systematic groups and on the life cycles of parasites.

Learning outcomes and their assessment

knowledge on body plans and physiological processes of animals of different taxonomic groups; on diversity of the kingdom of animals and on the structural adaptations and life cycles of parasitic animals. 4 laboratory tests
• skills to work with microscopes and to evaluate microscopic slides, to carry out dissections of animals, to search for zoological and ecological information and to analyze it. 4 laboratory tests
• competence to evaluate the importance of wild animals in the protection of animal and public health and in the protection of environment, to be competent and to be able to find information on the taxonomic status of different animal species.Exam

Each student must participate in at least one field trip during the semester. The teaching staff offers the topics and times of the excursions to the students at the beginning of the semester. 8 h

Requirements for awarding credit points

At the end of this part of study course students are evaluated by exam. To get the examination grade students must have positive results in all the tests of the first part of the course in autumn semester, have to be participated at all laboratory works, have passed all four laboratoruy tests, have to participated at least at one excursion and have to submit a report after the excursion.

Description of the organization and tasks of students’ independent work

The students have the rights to pass the laboratory tests if all laboratory works are visited and the results are accepted by the teacher. In a case, if the test result is negative, it must be repeated until positive. Students have to prepare a report after the excursion they have participated. The report must be accepted by the teacher.

Criteria for Evaluating Learning Outcomes

The laboratory works have to be defended and accepted by teacher. During semester four tests have to be passed. The testis evaluated with 1-5 points. The total number of points is calculated as the sum of points of all four tests multiplied by factor „3”. Thus the minimum number of points is 12 (1x4x3) and the maximum number of points is 60 (5x4x3). The number of points the student received at the end of first semester is added to the number of points received during the second semester. The exam grade is calculated according to the total amount of points:
79-100 (points): 4 (grade)
101-115: 5
116-130: 6
131-145: 7
146-160: 8
161-200: 9
Grade 10 might be given, if student has carried out study research for student conference at the faculty
