Teaching portfolio TEACHING EXPERIENCE
Courses at Tuscia University
I have a diverse range of experience in teaching at different levels (Bachelor and Master) in the field of Microbiology. My teaching activities started more 15 years ago at Tuscia University (Viterbo, Italy) with practical Lab, and it has been extended first in General Microbiology and then in Applied Microbiology mainly in the Environmental Science. Here below a list of the courses where I have been docent at Tuscia University.
Period Course CFU Education level
2006-2008 Methodological Laboratory 4 Biological Science Bachelor
2008-2011 General Microbiology 5 Environmnetal Science Bachelor
2009-2011 Microbial Ecology 6 Nature Conservation Master
2012- now Fermentation Biotechnology 6 Biotechnology Bachelor
2016-now Microbial Biotechnology 6 Biotechnology Master
Guest lectures at foreign universities
Recently I consolidated my teaching skills through international experiences, which have given me the opportunity to teach in English.
2014-2016 Environmental Microbiology 3 Master 20 Sapientia Romania
2018 Bioremediation of polluted soils 1 Master 10 Politechmic University of Bucharest Romania
2014- 2016 I taught in Romania, under ERASMUS Lifelong Teaching Program, at Sapientia University and subsequently in the 2018-2019 I was invited again as Invited Professor for teaching in the same institution . In 2018 again with ERASMUS Lifelong Teaching Program I was guest lecturer at University of Bucharest.
Bachelor students: 20 as main supervisor
Master students: 3 as main supervisor and 5 as co-supervisor
PhD students: 3 as principal supervisor and 2 (Polytechnic of Bucharest, Romania) as co-supervisor
I am regularly member of the examination team during Biotechnology BSc and Master Course oral presentation for graduating students, and I have been member of the assessment committee of PhD student at University of Tuscia.
Within the period 2011-2015 I was member of the Teaching Quality Committee (TQC) of the Bsc Biotechnology Course and from the last year I am member of TQC in Industrial Biotechnology master Course. TCQ has the role of evaluating student’s questionnaire and act corrective actions such as reduction on increase of teaching hours, program course adjustments.
TEACHING METHODOLOGY AND REFLECTION
In my 15 years of teaching experience, I learned that each student has a unique educational history, experiences and abilities and the docent should be able to catch and reach all members of the class, achieving their potential to be independent and stimulating their curiosity towards the subject.
In order to be clear as much possible, normally I try to use simple language guarantying terminology within the subject. I like to be not just informative but also impressive, trying to capture as much as possible the attention of the students. Generally I use simple examples to help the student to focusing on the theme and for better understanding biological mechanisms and functionality. Student’s facial expression and questions are useful feedback to advise me about the student’s understanding level and about what issues to delve into in more depth.
I believe that building competences within a subject requires active use of the tools, thus besides theory I include methodology approach to the theme and also research-based inquiry during which the students practice and explore their skills in this form of reasoning and develop a critical understanding of the scientific process.
Students generally consolidate the theoretic concepts taking active part in the learning trough practical exercises/lab/simulation which generally they find interesting. When this approach (lab training) is difficult to apply for the size of the class or for the typology of the subject, I like to use photos and videos.
I think that teaching is a flexible and adaptive process; courses should be adapted to meet current learning needs, responding to research improvements and student background change or, in some cases, to student desire and curiosity. Generally at the end of course I ask for feedback to modify the future courses.
According to the Teaching evaluation system of University of Tuscia*, the level of satisfaction of student obtained for Courses where I have been docent has been good or excellent.
• In 2016 I asked to be evaluated as Associate Professor in Microbiology area by MIUR (Italian Ministry of Education, University and Research) and I obtained the National Scientific habilitation (ASN), which allow me to be an Associate Professor.
