The diploma thesis is divided into a theoretical and a practical part. The theoretical part begins with explanation of basic concept of educational videos. The following chapter discusses advantages and possible barriers to using videos in education and presents examples of using videos in the classroom. The next chapter offers introduction to educational portals, selected YouTube channels, video tutorials and an example comparison of self-study versus university degree in a particular specialization. The practical part is divided into two chapters - Analysis of selected videos and Recommended steps for video production. The analytical part examines successful educational videos on YouTube in order to compile the recommended steps for creating quality video content in the last chapter. Included in the last chapter is also an educational video created by the author according to the previously recommended steps. This video was shown to students during a lecture at University of Economics, Prague. The students then filled in a short questionnaire as a feedback about the video. The conclusion summarizes the goals, results and benefits of the thesis.

PURPOSE: The purpose of this feasibility study was to explore the use of an online video intervention to prepare surgical patients to properly dispose of unused opioids. SPECIFIC AIMS: Describe the feasibility of recruiting, enrolling, randomizing and retaining participants who recently had a general surgery into the study. Describe the differences in opioid disposal by age, sex, education, and type of surgery for the entire sample and by treatment assignment. Describe the preliminary change in knowledge, behavioral beliefs, normative beliefs and disposal of opioids from baseline to post-intervention by group. Describe the relationship between social desirability and behavioral beliefs, normative beliefs and disposal of opioids. FRAMEWORK: The Theory of Reasoned Action was used to guide both the intervention and the measures. DESIGN: This study used a randomized controlled feasibility study to explore a novel video intervention to teach safe storage and disposal of unused opioids after general surgery. RESULTS: A total of 40 participants were enrolled in the study, average age was 44.7 (range 21-75 years), most were White, educated and employed. Recruitment took 11 weeks and the retention rate was excellent at 85%. Differences in opioid disposal was not significantly different by age, sex, education or type of surgery. The video intervention was positively received, but the majority (80%) still stored their pills unsecured. CONCLUSION: The results demonstrate that a video intervention addressing safe storage and disposal practices of unused opioids is feasible and more research is needed to determine efficacy in increasing rates of secure storage and disposal of unused opioid pills KEYWORDS: Opioids, opioid disposal, general surgery, video education

La ricerca mette a fuoco le attività formative messe in atto in Italia per dotare con urgenza le scuole secondarie di secondo grado italiane di docenti competenti in ambito CLIL e intende dimostrare l’impatto che questa metodologia ha sulla formazione e lo sviluppo professionale. Dal 2014 il CLIL è obbligatorio nelle classi terminali dei licei e degli istituti tecnici. Ciò ha generato una forte domanda di formazione da parte di istituzioni e docenti chiamati a insegnare discipline in lingua straniera. Questo lavoro esplora la possibilità di sfruttare la video-formazione per fronteggiare le preoccupazioni di quei docenti che, senza essere formati alla glottodidattica, sono chiamati ad integrare obiettivi linguistici al curriculum disciplinare. Il nostro lavoro parte dall’esame di un corpus di video-lezioni da noi raccolte ai fini di una ricerca-azione commissionata dal MIUR volta ad indagare il grado di innovazione implicata dal CLIL, per poi giungere a dimostrare l’importanza dell’auto-osservazione e dell’auto-riflessione sulla prassi didattica, fino a proporre l’introduzione dell’esercizio di microteaching nella formazione dei docenti CLIL. Una ricca riflessione sull’organizzazione concettuale della propria disciplina e sulla sua trasposizione didattica conduce i docenti a un interessate lavoro sulla mediazione della conoscenza che sviluppa le loro competenze professionali. / Focusing on teaching and training activities implemented in Italy to provide secondary schools with teachers able to teach in the CLIL context, our research aims at demonstrating the impact of this methodology in teacher training and professional development. Since 2014 this methodology has become compulsory for the Italian secondary terminal classes (except vocational high schools). A strong demand for training prompted from institutions and teachers, urgently required to teach disciplines in a foreign language. The MIUR has therefore set up university courses aimed at integrating languages and disciplines. Here we explore the possibility of exploiting video-training to face Italian teachers’ concerns, who are asked, without being trained in language teaching, to integrate linguistic objectives into their curriculum. We examine a corpus of video-lessons collected for a research set on behalf of the Italian Ministry of Education to investigate at what extent CLIL brought an innovation into the Italian Education. Once highlighted the importance of (self)observation and (self)reflection upon classroom practices, we propose the introduction of micro-teaching practice in CLIL teacher training. A fruitful reflection on the conceptual organization and the didactic transposition of their discipline leads teachers work on the linguistic mediation of knowledge which improves their professional skills.
