The evaluation of the subject is divided as follows:

- First test: 25% (Units 1, 2)

- Second test: 45% (30% Units 3, 4, 5; 15% Unit 6)

- Laboratory practical: 20%

- Seminars and Workshops: 10%

The evaluation cannot be considered positive if the student has not attended all laboratory classes.

Honors will be granted primarily to students who pass the subject on the first attempt. They will only be awarded in the "second chance" if the maximum number of honors has not been reached in the first attempt.

Students who do not pass the subject on the first attempt will be evaluated in the official exams of the Second Chance. In this session, they will be evaluated in the same way (percentages) through exams covering theoretical and practical contents, as well as the submission of seminar works. To receive the grade of "NO SHOW," students must not have participated in more than 25% of the scheduled evaluative activities.

Students who benefit from "recognition of part-time dedication and academic exemption from attendance" in accordance with UDC regulations must attend laboratory practices.

The final grade for these students will consist of two parts: the grade obtained in the laboratory practices, which will contribute 20% to the final grade, and the objective test, which will account for the remaining 80%. These grading percentages will be applied to both chances.

In exceptional circumstances that can be objectively demonstrated and properly justified, the responsible faculty may fully or partially exempt any student from participating in the continuous evaluation process. Students in this situation must pass a specific exam that leaves no doubt about the acquisition of the subject's competencies.

Once fraudulent completion of tests or evaluation activities is confirmed, the student will directly receive a failing grade for the corresponding academic year, whether the offense occurred in the first or second chance. If necessary, their grade in the first chance will be modified accordingly.

According to the "Regulations governing the study dedication regime for undergraduate students at UDC" (Art. 3.be 4.5) and the "Rules for evaluation, review, and appeals of grades for undergraduate and master's studies" (Art. 3 and 8b), students with recognition of part-time dedication and academic exemption from attendance must be able to participate in a training methodology and associated teaching activities that allow them to achieve the training objectives and competencies of the subject. Therefore, they will take part in a personalized system of guidance and evaluation tutorials that will serve to guide their independent work and monitor their progress throughout the course, as well as assess the level of competency development achieved.

During the tutoring sessions, aspects related to
the subject's content will be addressed, as well as the joint review of
submitted assignments.

Methodologies	Description
Guest lecture / keynote speech	In the lectures, the content of the respective topics will be introduced, highlighting the most important aspects and focusing particularly on fundamental concepts or those that may be more challenging for students. These are interactive sessions where students are encouraged to ask questions and seek clarification of ideas or concepts.
Laboratory practice	Preparation and study of crystalline substances. Interpretation of results using PC software. Use of morphological and structural models of crystals, as well as an introduction to characterization through X-ray diffraction. Students will keep a laboratory notebook in which they will describe their work in the lab, analyze the results, and draw the main conclusions.
Workshop	An eminently practical training activity designed with the aim of focusing on those aspects of the subject that are more difficult to understand. The work will be carried out individually or in groups under the guidance of the teaching staff.
Objective test	Tests will be conducted, comprising both open-ended and multiple-choice questions, as well as problem-solving exercises that will be like those done throughout the course. The aim is to assess the level of knowledge and skills gained by students and their ability to relate them and get an overall understanding of the subject.

Methodologies	Competencies	Description	Qualification
Laboratory practice	A5 A6 A7 A8 B6 B7 B8 C3 C7	We will evaluate the following aspects of laboratory work: - Work organization and safety. - Attitude, scientific curiosity, and degree of involvement in the work. - Quality of results interpretation. - Quality of the final report (laboratory notebook).	20
Workshop	A3 A5 B6 C7 C3	Both student responses and individual or group participation in the corresponding face-to-face activities will be graded. Occasionally, at the request of the teacher, students may be required to submit problem sets, which will also be evaluated.	10
Objective test	A3 A5 A7 B4 B7 B8 C8	Exams will be conducted to assess the content of the subject.	70
