No full textEducation in our society is a complex process, and different stakeholders have high expectations towards the world of education. Teachers should be able to teach not only their subject but also to foster autonomous critical thinking, in order to enable students to play an active, and constructive role in the society. Teaching requires a lot of human and professional skills because among students we can have both those who have difficulties to learn, and gifted students. A university teaching method is presented that allows to achieve excellent results, both as student motivation, and as skill acquisition in problem solving. Students are required to solve both logic and chemical problems, easy and difficult, with the aim of not discourage anyone. The emphasis is placed on visible reasoning and students are asked to explain, illustrate, argue, and demonstrate the various steps in problem solving. Appropriate strategies that facilitate the acquisition of cognitive skills and problem solving are suggested. Particular attention is being given to help students with difficulties in the course. Many students are able to deliver original and creative solutions. They pass the exam with excellent grades even though the course requests are substantial
La scienza per tutti: una intervista con Peter J. Fensham
No full textAfter providing some glimpses of his private life, Peter Fensham, a leading figure of the prestigious Faculty of Education, Monash University (and now emeritus professor at Queensland University, Brisbane, Australia), gives some suggestions about the conditions that help students to learn meaningfully. He began his career in the field of physical chemistry and then became an international authority in science education. His dedication to students and commitment to teaching a learner-centered science is palpable in many of his comments. This interview touches on many of the themes he addressed in numerous studies and research: the curriculum, the qualities of the expert teacher, and the decline of standards in schools. Although he is a supporter of a constructivist approach to teaching chemistry, he criticizes the extreme views of constructivism and explains the origin of his inner strength that made him a champion of “science for all”
Ragionamenti fondamentali nel calcolo stechiometrico: superare le difficoltà con la densità
No full textThe ability to solve problems in science subjects is an essential component of student’s education. Solving complex problems is a real difficulty for many students. This study, which extends for decades and involves students from different high schools, has been developed with the aim of finding strategies to increase students’ skills in the chemical problems where density is one of the data in the text. Using the results of various studies to the full, various strategies have been suggested and implemented. A consistent improvement of the results in the written examination tasks was obtained with the use of the ‘worked examples’ method. This method has been developed within the Cognitive Load Theory. A ‘worked example’ provides students with useful information on a solved problem: not only it shows the sequence of steps, but it comments them, illustrates, and explains them by motivating, and arguing them
