|---|---|
| Knowledge and understanding: The main aim of the chemistry course is to provide students with the methodological basis of the scientific investigation in the chemistry field. The course focuses on understanding the molecular nature of the matter and the chemical processes leading to chemical applications in several fields of the chemical engineering. The purpose is to develop in students the ability to apply their chemical knowledge and skills to the solution of theoretical and practical problems in chemistry. Applying knowledge and understanding – engineering analysis Chemistry course is aimed at ensuring that students become conversant with the following main aspects of chemistry: Classification of matter and chemical elements; types of chemical reactions and system reactivity, stoichiometry; atomic structure and periodic properties; aggregation states; solutions; chemical equilibria; electrochemistry. Applying knowledge and understanding – engineering design The main abilities and skills that students are expected to have developed by the end of their Chemistry course, are as follows. • To be able to balance reactions • To be able to calculate pH of solutions • To be able to solve simple chemical and electrochemical equilibria • To be able to use Redox potentials Making judgments - engineering practice: Knowledge base is expected to be extensive and well beyond the work covered in the programme. Conceptual understanding is expected outstanding, good or at least of acceptable level. Problems of a familiar and unfamiliar nature are expected to be solved with efficiency and accuracy; problem-solving procedures are expected to adjusted to the nature of the problem. Communication skills – transversal skills: Communication skills are expected to cover both written and oral communication. Performance in transferable skills is expected to be generally very good, good or at least acceptable. Learning skills – transversal skills: A specific training in learning skills of chemical concepts is provided during the course also instilling in students a sense of enthusiasm for chemical concepts, an appreciation of their applications in different contexts and most of all involving the students in an intellectually stimulating and satisfying experience of learning and studying. |

| Teaching Methods | |
|---|---|
| The teaching is developed through lectures, tutorials, chemistry exercises and mid-term verification tests. |
| Verification of learning | |
|---|---|
| The procedures used for the assessment of students' achievement in chemistry will correspond to the knowledge, abilities and skills that will be developed through the chemistry programme. The assessment of student achievement includes: • Formal examinations, including a significant proportion of 'unseen' examinations during the lectures (interactive lessons) • Problem-solving exercises • Mid-term verification tests dealing with the basic concepts developed as the course goes on. Evaluation criteria to pass the Chemistry exam Although all students are expected to demonstrate that they have acquired knowledge, abilities and skills in the areas identified in the foregoing sections, it is accepted that there will be significant differences in their attainment. The following criteria are suggested as indicators for the highest and lowest levels. Attainment Level A (highest) – (to get full, top marks in the Chemistry exam – 30/30 Lode) : _ Knowledge base is extensive and extends well beyond the work covered in the programme. Conceptual understanding is outstanding. _ Problems of a familiar and unfamiliar nature are solved with efficiency and accuracy; problem-solving procedures are adjusted to the nature of the problem. _ Performance in transferable skills is generally very good. Attainment Level E: (lowest – 18/30) _ Knowledge base is acceptable in relation to some of the content covered in the programme. _ Problem-solving ability extends to simple 'standard' problems, following routine procedures. _ Transferable skills are rudimentary. |
