fields of study / plans the course is directly associated with

• Anthropology (programme PřF, N-AN)
• Anthropology (programme PřF, N-ANT)

Course objectives

The course aims to present students with advanced recording and visualization techniques and their employment in the field of biological anthropology. In lab classes, students will be trained in processing 2D and 3D spatial digital data while being introduced to various computer programs for processing surface and volume 3D data. In addition, students will be trained in the employment of image and shape analysis software.

Learning outcomes

At the end of the course students will be able to:
- collect 3D spatial data of static as well as dynamic biological objects, such as bones or human body parts,
- process digital 2D and 3D data,
- analyze morphology of biological objects by means of geometric morphometrics,
- apply histomorphometric methods,
- comprehend the principles of traditional and advanced imaging techniques.

Teaching methods

Lab classes taught in blocks for a limited number of graduate students enrolled in Anthropology Program seriously interested in the topic, in exceptional cases for students from other disciplines (by prior arrangement). The number of participants is limited by technical equipment (max. 10 students). Students work individually and in groups on a given practical task and process laboratory protocols under guidance of an instructor.

Assessment methods

During the semester, three partial tests will be administered, each at the beginning of one of the three seminars. The tests will focus on knowledge gained in previous lectures of the block. The tests will be conducted online via ROPOT in IS. Each test will consist of twenty multiple-choice questions, with 1-4 correct answers, focused on knowledge gained in previous lectures of the block. The test will be evaluated as follows: for the selected correct answers, the relative score will be added (0.25–1 point, depending on the number of correct answers in the given question). For each chosen wrong answer, one-third of a point will be subtracted. This means that one point for one question will be awarded only for selecting all the correct answers and only them. To pass the test, a gathering of 50 % points is necessary.
For each seminar, students will elaborate a protocol according to the assigned task.
To obtain the credit, it is necessary to actively participate in all three seminars, submit three elaborated protocols (or their corrected versions according to the teachers' comments), and pass all three continuous tests. The student has the right to one absence from the seminar and failure to pass one continuous test. In case of the absence, the credit will be awarded after passing the final oral exam. For the failed test, the student must pass the final test, consisting of 60 questions focused on the knowledge acquired during the whole semester. The type of questions, their scoring, and the limit for passing the final test will be the same as for the partial tests.
