This proposed didactic sequence on Quantum Dots was applied to a 2nd
grade high school class, made up of 44 students in the year 2022 and the last part of this
didactic sequence was applied to that same class, already in 3rd grade of high school in
2023, in the morning shift, at a Public School in Manaus. This didactic sequence
required five (05) classes lasting 50 minutes each, the objective of which was to provide
students with an understanding of the topic of quantum dots and their applications in the
development of new technologies in various areas. To prepare this didactic sequence,
several didactic resources were used to facilitate students' learning throughout classes,
such as the use of slides, short videos on the topic covered, the use of scientific articles
and materials from technology websites that address this topic, a conversation with
students so that they could explain what they learned about quantum dots and their
applications in everyday life. The students were divided into several teams, with a
maximum of five members, and a digital game called Show do Milhão dos QDs was
created for this approach. The framework adopted in this work was David Ausubel's
Meaningful Learning Theory (TAS) and the approach used in this didactic sequence
was the Science, Society, Technology and Environment (CSTA) approach, with the aim
of showing how the use of technology points Quantum technology can help solve
problems faced by society. Information on students' knowledge regarding this topic was
collected through two questionnaires, an initial questionnaire consisting of four open
questions, to determine whether there was any prior knowledge on the part of these
students regarding this topic, in addition to a final questionnaire consisting of five open
and closed questions, with the aim of verifying whether there was an evolution in the
learning process in relation to this topic. In addition to the proposal for the digital game
“Show of the million QDs”, to assist in the learning process of the students involved in
this approach, an evaluation questionnaire for this digital game was also used, present in
the didactic sequence.
