Triatominae biochemistry goes to school: Evaluation of a novel tool for teaching basic biochemical concepts of chagas disease vectors

Abstract

We evaluate a new approach to teaching the basic biochemistry mechanisms that regulate the biology of Triatominae, major vectors of Trypanosoma cruzi, the causative agent of Chagas disease. We have designed and used a comic book, "Carlos Chagas: 100 years after a hero's discovery" containing scientific information obtained by seven distinguished contemporary Brazilian researchers working with Triatominaes. Students (22) in the seventh grade of a public elementary school received the comic book. The study was then followed up by the use of Concept Maps elaborated by the students. Six Concept Maps elaborated by the students before the introduction of the comic book received an average score of 7. Scores rose to an average of 45 after the introduction of the comic book. This result suggests that a more attractive content can greatly improve the knowledge and conceptual understanding among students not previously exposed to insect biochemistry. In conclusion, this study illustrates an alternative to current strategies of teaching about the transmission of neglected diseases. It also promotes the diffusion of the scientific knowledge produced by Brazilian researchers that may stimulate students to choose a scientific career.Copyright V C 2014 by The International Union of Biochemistry and Molecular Biology, 42(4): 323-330, 2014.

Communication in Neglected Tropical Diseases’ elimination: A scoping review and call for action

“…Didactic education was used to explain the CD transmission cycle and spread information about home-based preventive practices through classroom lessons [ 89 , 92 , 102 ], workshops [ 94 ], contests [ 97 ] and public activities in community settings [ 95 ]. Education-based strategies also distributed information to the community through booklets [ 84 , 101 , 103 ], video and radio resources [ 90 , 98 ], and mobile telephones [ 91 ], as well as other materials such as posters, printed bags, magnets, and lottery tickets with key messaging used for community outreach [ 78 , 90 , 92 , 95 ].…”

Constructing online concept maps in CMap Cloud collaboratively: Connecting pathways in case scenarios

“…The construction of concept maps by the student as an active participant can be a generative learning strategy 2 . By developing their own concept maps students can learn to: organize and systematize knowledge; uncover organizational relationships; focus on the most relevant concepts and interconnections; have an overview of the represented process; identify alternative concepts and difficulties; formulate new concepts; foster problem solving 3–5 …”

“…2 By developing their own concept maps students can learn to: organize and systematize knowledge; uncover organizational relationships; focus on the most relevant concepts and interconnections; have an overview of the represented process; identify alternative concepts and difficulties; formulate new concepts; foster problem solving. [3][4][5] This proposal is synthesized in Figure 2. The duration of the entire process can vary greatly with the complexity of the proposal, with an average period of 1 week being suggested.…”
