Videos were a useful complement to the laboratory compendium, allowing students to focus on conceptual understanding of the exercise and the related theory.   KEYWORDS: laboratory exercises, microbiology, videos   OBJECTIVES  1.  Example on the use of short videos to enhance learning in practical laboratory exercises     DESCRIPTION  Eight short videos were produced to enhance student learning in laboratory exercises in a second semester Bachelor of Engineering compulsory course in Biological Chemistry (7.5 ECTS) at the Technical University of Denmark (DTU) [1]. The videos demonstrate basic techniques applied in the microbiological laboratory, and were made freely available to students through YouTube and DTU´s podcast channel [2]. Links were included in the written laboratory compendium to allow easy access. Each laboratory session started with an introduction of the exercise showing the related video(s). Students were encouraged to watch the videos before and after exercises to enhance learning. A written evaluation was performed at the end of the course, where 83% of the students reported having seen the videos outside class and all students felt that videos aided their understanding of the laboratory techniques. Suggestions for improvements included shortening the videos and producing additional ones explaining key concepts. Teachers reported that less time was spent on explaining what to do at the exercise thus allowing them to focus on solving misconceptions. In conclusion, videos explaining laboratory procedures were found to be a useful complement to the laboratory compendium, allowing students to focus on conceptual understanding of the exercise and the related theory.

Introduction Digital learning objects, such as videos, are increasingly being used as a complement to traditional text books and represents innovative tools to enhance student learning (1, 2).  The use of short videos, uploaded on YouTube, was used to introduce students in a 7.5 ECTS B. Eng., course in Biological Chemistry at the Technical University of Denmark (DTU) to basic techniques being taught during the practical laboratory exercises.

Description of the main content of the 8 videos together with screenshots from YouTube and Quick Response (QR) codes that allows easy access for students using e.g. a smartphone. Study design • 8 short videos (3-7 min) (Table 1) • Uploaded on YouTube and DTU´s podcast channel • Links (URL and QR code) included in laboratory compendium • Videos shown before each exercise References 1.
