Teaching methodology
The teaching of the subject takes place in the framework of lectures, practice and laboratory practice. The lectures basically introduce students to the information defined by the knowledge competence elements using the technique of frontal education. The application and acquisition of knowledge at the skill level take place in laboratory exercises and classroom exercises, where ability competencies can be acquired through guided task solving and individual project work.

General rules
Learning outcomes are assessed on the basis of a mid-year written summary performance measurement and three sub-performance measurements. Summative academic performance appraisal is a complex, written way of assessing the knowledge and ability type competence elements of the subject in the form of an in-house dissertation, which requires the necessary lexical knowledge during the performance appraisal, the available working time is 60 minutes. Partial performance assessment (homework and computer task solutions): a complex way of assessing the knowledge, ability, attitude, and independence and responsibility type competence elements of a subject, which is implemented in an individually prepared semester homework, a computer task solution, and a five-part small task solution.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 1 | |
| Purpose, description: | Summative assessment collectively examines and measures students ’learning outcomes defined by knowledge and ability type competencies. Accordingly, the summative assessment assesses the acquisition of the designated theoretical knowledge, as well as the existence of knowledge and skills acquired in practice. The summative assessment focuses 65% on theoretical knowledge and 35% on application skills. They will be completed on the date specified in the academic performance assessment plan, expected to be the 13th week of education. 25 points can be obtained in the summary performance evaluation, a minimum of 40% must be achieved. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, point-in-time personal act | |
| Number: | 1 | |
| Purpose, description: | The basic aim of partial performance assessment is to examine the existence of learning outcomes belonging to the attitude and autonomy and responsibility competence group. The way to do this is realized in a purely computer task solution. Successfully solving the CAM programming task to be solved in the classroom requires similar knowledge, skills, and attitudes as solving the semester project task. A maximum of 25 points can be obtained with the task, a minimum of 40% must be completed. | |
| Mid-term assessment No. 3 | ||
| Type: | formative assessment, project-based, complex | |
| Number: | 1 | |
| Purpose, description: | The basic goal of partial performance assessment is to examine the existence of learning outcomes belonging to the attitude and autonomy and responsibility competence group. The way to do this is to create a project task that can only be done individually and then present it in front of the practical group. The assignment of tasks must be finalized by the 4th week of education. The content and form requirements and evaluation principles of the completed project task are included in the terms of reference. It will be completed on the date specified in the academic performance evaluation plan, expected to be in the 14th week of education. A maximum of 25 points can be obtained with the task, a minimum of 40% must be completed. | |
| Mid-term assessment No. 4 | ||
| Type: | diagnostic assessment | |
| Number: | 1 | |
| Purpose, description: | The basic goal of partial performance assessment is to examine the existence of attitudes and learning outcomes belonging to the autonomy and responsibility competence group. The way to do this is to create and present five small tasks that can only be created individually. The assignment of tasks must be finalized by the 4th week of education. The content and form requirements and evaluation principles of the completed tasks are included in the terms of reference. It will be completed at the dates specified in the study performance assessment plan. You can get a maximum of 5-5 points with the tasks, there is no minimum point limit. | |
