Language Skills Developed
Transferable/Scientific Skills Developed
To observe and to understand why this physic phenomenon happens and which laws govern it.
• 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 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 stimulate the curiosity of the students in order to introduce : the two laws of physics: refraction and reflection of the light, the composition of the solar light as a sum of electromagnetic waves with different frequencies, the light as a minimal part of electromagnetic waves: from radio waves to gamma rays.
• 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: half hour to watch the video, it can be stopped when it is necessary and the rest of the time for the lesson between the teacher and the students and to look for other videos or information about this phenomenon.
• The teacher must ask questions to the students about the parts of the video which are less complete ( for example : why is the form of the rainbow an arc?) and he must stimulate them to ask other questions. Then he must lead them to the explanation, including research on line. He must complete the video with clarifications and in depth information . He can also tell the history of the rainbow starting from Alessandro di Afrodisia, Aristotele, Cartesio to nowadays
• Normally students do not have any trouble to understand these laws
• Strength: This video is easy and it explains clearly the refraction law, and the dispersion of the light. The animation is attractive and the explanation why the observer sees the colour in that order is good. • Weakness: This video is complete enough but it speaks only about the rainbow. It could speak about the position of the sun compared to the observer. Also it could explain a lot about the form of the rainbow. • Scientific reliability: it is good, but it could be more exhaustive. • Pedagogical value: Collaborative learning and self-direct learning are used in this lesson. The role of the teacher is to lead the students to ask questions and he must help them to find answers.
