Educational Goals

The course aims to achieve the following learning outcomes for students:

• Acquiring knowledge in advanced Mathematics concepts and skills for food science and technology.
• Application of Mathematics in the food industry in the form of computational exercises.

General Skills

• Students must be capable of using advanced mathematical methods for solving problems in food science and technology.
• Promotion of analytical, creative and inductive thinking.
• Decision-making.
• Autonomous work.
• Teamwork.

Teaching Methods

Face to face:

• Lectures (theory and exercises) in the classroom.

Use of ICT means

• Lectures with PowerPoint slides using PC and projector.
• Notes, solved and unsolved problems in electronic format. Each session involved both a faculty lecture and student participation in problem-solving exercises.
• Posting course material and communicating with students on the Moodle online platform.

Teaching Organization

Students Evaluation

Evaluation methods:

• Attendance at class and participation in discussions, and solving exercises in the classroom is rewarded with 20% of the final grade.
• Written final exams (80% of the final grade).

The evaluation criteria are presented and analyzed to the students at the beginning of the semester and are available at the course website.
