MICOLOGIA E VIROLOGIA VEGETALE
Module MICOLOGIA VEGETALE

Academic Year 2023/2024 - Teacher: ALESSANDRO VITALE

Expected Learning Outcomes

The teaching course aims to ensure the acquisition of basic knowledge of taxonomy, biological aspects and diagnostic criteria of the "key" phytopathogenic fungi. The student will acquire skills in identifying some effective management indications both in the nursery and in the open field and in professional updating for this area.

Exercises and seminars will always be aimed to identifying the fungal disease and, comprehensively, to the ability to problem solving.

Specifically, the student is expected to acquire comprehension skills, communicative abilities, and independent judgment according to the Dublin descriptors, as follows:

Knowledge and Understanding - (Dublin 1) [Knowledge and understanding]

At the end of the course, the student must demonstrate a basic understanding of diagnostic and taxonomic criteria, symptomatology, biological aspects, and fundamental principles of combating phytopathogenic fungi.

Assessment Method: Oral exam.

Applied Knowledge and Understanding - (Dublin 2) [Applying knowledge and understanding]

By the end of the course, the student should be able to apply the knowledge acquired to identify fungal alterations, understand their symptoms and biology, provide useful sustainable control recommendations in nursery and field settings, and evaluate and interpret experimental and literature data.

Assessment Method: Oral exam.

Independent Judgment - (Dublin 3) [Making judgments]

At the end of the course, the student should demonstrate the ability to formulate informed interpretative judgments based on the acquired knowledge. They should be able to weigh various aspects of plant mycology in research activities extracted from scientific publications and autonomously analyze plant pathogenic issues with fungal etiology.

Assessment Method: Oral examination following the presentation of a scientific publication.

Communicative Skills - (Dublin 4) [Communication]

By the end of the course, the student should demonstrate the ability to use technical terminology appropriately, adapt oral and written communication forms to the required level and specific purposes. Similarly, the student should be able to analyze and synthesize a scientific publication and present their work to colleagues.

Assessment Method: Oral exam aimed to assess the student's ability to summarize a scientific article.

Learning Skills - (Dublin 5) [Lifelong learning skills]

Upon completing the course, the student should be able to keep their knowledge and skills up to date, grasping essential and relevant aspects of the course for their professional context within a legally, ethically, and scientifically correct framework. They should understand the topics both within a group and independently, connect not only the subjects covered during the course but also identify connections between the themes discussed in this discipline and other areas.

Assessment Method: Partially through an oral interview.

Course Structure

Teaching course includes theoretical lessons for a total of 28 hours and other practical activities (classroom and laboratory exercises, educational visits, seminars, etc.) for also a total of 28 hours. If teaching is given in a mixed formula or remotely, necessary changes may be introduced to what was previously stated in order to comply with the provided and reported syllabus. Frontal lessons and lectures, exercises and educational visits. For the lessons we will make use of multimedia presentations, slides, computer databases, summary and explanatory diagrams in paper format that will allow us a better undertsanding of the basic concepts and the basics of phytopathological mycology. The laboratory exercises will be aimed at the recognition of diseases and the identification of fungal pathogens. Field visits and educational excursions will take place on other days and times to be agreed with the students by phone (095-7147413). Learning assessment can be done remotely if necessary.

Information for students with disabilities and/or specific learning disabilities (SLA)

As guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Inclusion - Services for Disabilities and/or DSAs), in the person of professor Anna De Angelis.

Required Prerequisites

Although there are no mandatory prerequisites, the required pre-knowldge involves basic understanding of biology and plant pathology

Attendance of Lessons

although it is not mandatory the lesson frequency is strongly recommended also according to practical nature of teaching course.

Learning Assessment

Learning Assessment Procedures

Learning evaluation will be assessed by oral examinations. No checks in progress are foreseen. A single meeting is planned in the mid of course to ascertain the learning level and the interest degree of the students with clarification of doubts. The evaluation of the student's preparation will take place on the basis of the following criteria: learning ability and level of depth of the topics covered, quality of the contents, ability to connect with other topics covered within the program, properties of synthesis and exposure, ability to report practical examples and student's reasoning skills.

Verification of learning can also be carried out by online way if it will be necessary.
