Teachers use modern technologies to attract students to science and give them better understanding of it. Through technology, students can explore science content in a way that would not otherwise be accessible.

“As a part of my lesson on the Universe, I showed a video that presents celestial objects in their real sizes. Students were amazed how big the Sun is and that something even bigger exists. There are situations when explanation does not work; visualisation is much better.” (primary school teacher)

Not many videos and visualisation are available in the Czech language. The only bigger source of educative videos in Czech is Khan Academy.

Examples of sources used by teachers

Khan Academy
The US concept introduced in the Czech Republic in 2013. Almost 2,000 videos are available in its Czech version with 30,000 visitors per month. The videos are usually under 10 minutes long and the content is explained in a simple and attractive way. They present mainly Physics and Mathematics topics and cover the whole Czech curriculum of the two subjects. As far as we know, in the Czech Republic, videos are not used for the flipped classroom approach as it is common in English speaking countries.

Documents by Czech TV
Several documents available online free of charge such as “Date with Physics” or “Michael's experiments”.

Methodical Portal RVP
The Czech portal RVP ( provides online space for teachers to share and discuss their experience, inspiration and lessons. It contains a database with animations of physical and chemical experiments, which cannot be done in the class e.g.:
Physical animations –
Physical Java applets –
Videos showing world under the microscope –

Open Science
Animations made by the Czech Academy of Science explain 10 scientific questions in an attractive way, e.g. how the Universe was created or How a nuclear power plant works. See the link:

How things are done (Jak se to dela)
Videos available at present manufacturing processes that cannot be shown in the class.Strong points and opportunities:• Using audiovisual aids is not costly – it is easy to use visual aids with basic equipment (lack of funds to purchase modern aids was marked as a problem by 75% of teachers in questionnaires)
• Khan Academy has many benefits compared to a common lesson, such as the possibility to pause the video, or watch it again at any time. Thanks to a different approach to the topic and a different speaker, the videos are more attractive to students. The database of the lectures created by Czech authors is growing.
• We do not have any evaluation of Khan Academy impact on learning in Czech classrooms. However, there is an evidence from US classrooms that students enjoy to learn through video lectures and that it increases their interest in science.
• Students in general reflect positively on using technologies in lessons. According to both students and teachers, it is stimulating and makes the lessons more attractive.Limitations:• To find a proper and good quality animation or any other aids may take a long time. There are not many databases or portals where teachers would find easily what they need. Teachers mostly browse on internet.
• Mixed quality of aids from internet. There is no guarantee that the content is explained correctly and unbiasedly.
• Students may get bored if the same aids are used too often by teachers. It is advised to alter the visual aids with hands-on activities or any other methods that ensure a diversity of teaching in the class.Added value with regards to the 3 topics of the MASS project:• Apart from the fact that videos and animations are fun for students, teachers mostly highlighted the effect of showing “what you cannot experience in real” as the added value.
• Visual aids communicate the content by sound and image. That is why more types of learners can be engaged compared to using a text or a lecture.Any prerequisites needed:None
