Resumo:
The aim of this project was the evaluation about the adequacy of several experiments using data-logging to enhance student’ learning about acid/base. Twenty-two students, aged 14-16 years old, were involved. Students had to plan investigations, analyze data and to formulate conclusions based on calculations and graphs. To evaluate student’ learning data were collected using several instruments: questionnaires, observation, group interviews, group discussions and participants' reflections about the work developed. The results suggested that these experiments strongly enhanced the students’ understanding of acid/base and improved students’ experimental and investigative skills in using ICT in chemical laboratory.
