| Methodologies |
| Methodologies | Description |
| Introductory activities | A first session to the presentation of the course where the various sections contained in the teaching guide will be presented will be devoted (learning aims, contents, methodologies, assessment, sources of information...), and where the student may raise any doubt or question regarding the same. Also a printed version of this teaching guide and a detailed schedule of the activities will be delivered. This documentation, along with a full version of the teaching guide, will be available to the student in the Moodle platform. |
| Guest lecture / keynote speech | Throughout the semester, 25 lectures of 50 minutes about the basic contents will be taught. Professor will explain the theoretical aspects of the subject help of drawings, diagrams and computer presentations (these contents, along with links to other files and web pages, videos..., will be available to the student in the Moodle platform). Professor will also resolve issues raised by the student. Explanations of the lectures will be assimilated by the student through the development of notes and subsequent study with the help of the recommended literature. Also, it is recommended that the student has previously reviewed the fundamental aspects of these lessons. |
| Laboratory practice | A total of 15 hours of laboratory practice will be given, and these will be mandatory. Practical sessions will consist of observing different slides and identification of tissues and organs (both plant and animal), also addressing the fundamentals of basic histological techniques. During these sessions, professor will present the objectives of the practice and will guide the student observations, making clear the doubts that arise about the identity of the observed structures. |
| Collaborative learning | Throughout the semester, 6 sessions (50 minutes long), will be spent working in small groups (approximately 10 students). During collaborative learning sessions, various issues related to the contents of the subject will be addressed (and discussed), and will be performed activities for which will be used specific literature (printed or through the use of electronic resources). |
| Objective test | Two of the collaborative learning sessions will be dedicated to make objective testing, to determine the degree of assimilation of the contents. The delivered activities shall be resolved in small groups. |
| Mixed objective/subjective test | Student will be assessed continuously through test questions and/or short-answer questions about the contents of lectures and small group sessions (collaborative learning sessions). Two theoretical and one practical exams will be made during the semester, and a final exam for students who either have not exceeded these theoretical examinations and/or practical, or have not been presented to them. |

| Assessment | ||
| Methodologies | Description | Qualification |
| Objective test | Two (written) tests will be done: the first will include content related to plant histology, and the second will address contents related to animal histology. These tests will consist of a combination of different types of questions: multiple-choice questions, short answer, identification schemes/images, complete and/or association. Assessment of study programme competencies A1 and A29. |

| Laboratory practice | Students will undertake a practical examination which will represent 20% of the final grade. The practical examination shall consist of the identification and interpretation of images of histological sections and / or slides, both plant and animal. Assessment of study programme competencies A1, A4, A5, A11, A29 and A30. |
20 |
| Mixed objective/subjective test | Two theoretical partial exams will be made during the semester (the first will include lessons 1-9 of the program and will represent 40%, while the second partial will include lessons 10-22 and will represent 60%), and a final exam for students who either have not exceeded these theoretical examinations and/or practical, or have not been presented to them. These theoretical examinations consist of multiple choice questions (multiple choice) and/or short-answer questions on the contents of lectures and small group sessions. Assessment of study programme competencies A1 and A29. |

Consideracións xerais: O alumno disporá de dúas oportunidades oficiais para superar a materia (final de cuadrimestre e xullo). Así mesmo, realizaranse 2 exames parciais teóricos e un exame práctico liberatorios ao longo do cuadrimestre. A cualificación de Non Presentado aplicarase unicamente no caso de que o alumno non participase, durante o curso, en ningunha actividade da materia (teórica ou práctica), ou ben se non se presenta na convocatoria final de xullo. Aspectos e criterios de avaliación: Na oportunidade de final de cuadrimestre teranse en conta, para o cómputo da cualificación global, os distintos apartados recollidos no sistema de avaliación, debéndose superar cada un destes para proceder ao cálculo da cualificación final (global). Como xa se indicou, realizaranse dous exames parciais teóricos escritos (e un práctico) durante o período lectivo da materia (o primeiro dos parciais representará un 40%, mentres que o segundo suporá o 60%), así como un exame final para os alumnos que ou ben non superasen devanditos exames teóricos e/ou práctico, ou ben non se presentaran aos mesmos, representando o 65% da cualificación final. O exame práctico suporá o 20% da cualificación final. A realización das actividades expostas (proba obxectiva) durante as sesións en grupo reducido suporá o 10% da cualificación final, mentres que a asistencia ás clases teóricas (maxistrais e sesións en grupo reducido) e prácticas suporá o 5% da cualificación final. Na oportunidade final de xullo poderase/n recuperar a/s parte/s non superada/s, teórica (no seu conxunto) e/ou práctica, representando éstas o 80% e o 20% da cualificación final, respectivamente. Nota: Para que se teñan en conta as cualificacións nas distintas actividades suxeitas a avaliación é preciso superar (alcanzar o 50% da cualificación) cada un dos apartados que integran o devandito sistema de avaliación. De non alcanzarse dita puntuación nalgunha delas e aínda que a media dos distintos apartados sexa igual ou superior a 5 (sobre 10) a materia figurará como suspensa e a cualificación de 4,5. |

It is strongly recommended to read or work on the subject of lectures and small group sessions and take notes. Students to find a particular difficulty in following classes or in addressing the issues that make up the program (both theoretical and practical) can go to individualized tutoring (see schedule Moodle platform). |
