Language Skills Developed
Transferable/Scientific Skills Developed
To observe , to understand ,to acknowledge the laws of physics that govern the phenomena
• The general aims are to develop the observation skills .
To acquire and to interpret information in a critical way through different contexts and through different communicative instruments.
To estimate the scientific credibility of the source and to discern the difference between facts and opinions.
To communicate and to understand different languages (daily, technical, literary, scientific) and to use them in different contexts.
• The linguistic aims are to teach students a correct scientific language . They will have to read or to watch and to understand a scientific article or video. They will have to use a correct language when they have to explain a scientific topic.
• The specific aims are to introduce the reflection of the light and the laws that govern this phenomenon.
• The target group age is 16 /18
• Level of competence in English is B1/B2.
• The time required to use the resource with the students is about two hours: one hour is needed to watch the video, it can be stopped when it is necessary. Another hour is needed for the lesson between the teacher and the students, to do some exercises and to watch the video a second time if necessary.
• While watching the video, the teacher must stop it to add information or explanations and to allow the students to ask questions, to take notes about the topic and to copy the patterns.
The second hour is dedicated to formalise the topic ,to do some exercises about Snell’s law and to introduce the consequences of refraction.
• Normally students have some trouble to understand the refraction of the light and Snell’s law. They find it difficult to understand why the light changes speed when it comes in from a medium to another and why the incident ray is bent. To overcome the problem, in this video it is used the example of the marching band and the students usually understand this phenomenon.
• Strength: The refraction is not easy to understand, but this video explains the topic clearly and in great detail. the explanation about the bending of the light when it comes in from a medium to another is particularly well done. Every concept explained is supported by illustrations and patterns that help the students to understand.. • Weakness: I have not found any particular weakness if not that the teacher sometimes speaks too fast, but he repeats the concepts so many times and the drawings are so clear that there should not be any problem. • Scientific reliability: it is very good. • Pedagogical value: Collaborative learning ,self-direct learning and frontal lesson are used in this lesson.
