The entire subject is going to be taught in English. All teaching materials will be written in English, including the laboratory recipes. The oral presentation given by the students will be also carried out in English.
Requirement: students need to have (minimum) a B1 level in English.
 

The teaching methodology involves:

• Master classes for the theory contents, to cover the basic concepts underlying novel materials and their incorporation in miniaturized extraction and analytical separation methods, using all audiovisual media, mainly the slide projector, printed materials... These classes will serve as a conceptual theoretical scheme of the different subject, while analyzing and summarizing information coming from different sources, and ensuring a proper discussion of interesting and/or difficult topics for the students. In all cases it is pursued a high participation of students within the dialogue, the critical discussion, generating controversy, and assuring adequate analysis. All presentations and materials will be given to the students through the Virtual Classroom (Moodle software).
• Laboratory practices. This is a key part of the entire teaching approach. In the laboratory practices the students (properly guided by the professors) will develop practical works devoted with analytical sample preparation approaches requiring microextraction techniques with novel materials. In all cases, the compatibility of those methods with conventional Analytical Chemistry techniques and instrumentation will be covered, the analysis of the obtained results will be in situ discussed... As a requirement to enter the laboratory, students must understand the laboratory recipe, while performing a review of the theoretical contents involved in each laboratory practice, and the preparation of a scheme of the entire working plan for the lab. At the beginning of each laboratory practice, the professor will summarize the key aspects: objectives, fundamentals and experimental procedure by teaching a short seminar. At the end of each laboratory practice, the student will analyze the obtained results and the observed phenomena and will respond to questions made by the professor at the beginning, during, or at the end of the practice session. All these aspects will be included in a report, that will be submitted for correction at the date set.
• Mentoring classes. These individual or collective type of classes will cover specific parts of the subject. I.e. the use of updated research articles related with novel materials and microextraction method, to ensure the proper acquisition of skills related to the subject by the student, particularly ensuring that the students are able to properly classify advanced in microextraction techniques for analytical sample preparation, while identifying the type of novel material used and the reasons for its selection of the particular application, or, in case of inadequacy utilization in the given application, to discuss ways of improvements. In particular, this will be addresses through oral defenses and discussion of certain articles on the topic. Furthermore, it is recommended the assistance to office hours as a good alternative to improve the success following the subject. Apart from office hours, the Virtual Classroom will include several tools to solve particular o generic questions. Students are encouraged to use all elements and tools provided by the Professor.

Students will be evaluated following these rules:

Continuous evaluation:
Evaluation 1) Evaluation of other tasks, including the oral presentation. (15%)
Evaluation 2) Evaluation of laboratory practices, including laboratory skills, organization, attitude, method and order. (15%)
Evaluation 3) Assistance and participation in all activities of the class. (5%)
Evaluation 4) Evaluation of the report/memory of the laboratory practices, giving value in that report/memory to the organization of ideas, quality of writing, presentation and discussion of results, together with the maturity in the conclusions. (15%)
Evaluation 5) Evaluation of the tests posted in the Virtual Classroom (Moodle). (15%)
Evaluation 6) An exam that accounts 35% in the final grade.
Those activities not performed by students will be graded with a 0,0.

***The continuous evaluation only applies for the 1st call.

The Unique evaluation (EU from the Spanish abbreviations of “Evaluación Única”) will take place in both calls of the subject:
Those student wanting to be evaluated through the EU (and not with the continuous evaluation in the 1st call) must send an email to the coordinator of the subject (Verónica Pino Estévez), and this has to be done the first month since the beginning of the classes (see new articles 5.4 and 5.5 of the new rules at University of La Laguna). Such EU will include: 1) a laboratory exam (40%), 2) the presentation of all laboratory reports of the practices (6%), 3) a questionnaire requiring short responses to the questions (24%), and 4) an exam requiring longer responses to the questions (30%).
 
***In all cases, the attendance to the laboratory practices is mandatory during the dates established in the timetable.

Recommendations:
• To systematically solve all problems given, to secure the knowledge acquired during the teaching lessons.
• To use the recommended scientific literature to secure the knowledge, and to improve the skills on a certain topic.
• To utilize the “office” hours to solve questions and concerns arisen during the subject.
