PROBLEM-BASED LEARNING (PBL): TRADITIONAL PERIODIC TABLE versus PTABLE

Problem-Based Learning. Periodic Table of Elements. Chemistry teaching.

Science curricula have evolved considerably in recent years. When it comes to the Periodic Table of Elements (TPE) there are still difficulties, both in the way it is presented by the teacher and in the understanding of the student. Based on the need to seek new teaching methods that more actively involve the student in their own learning, the present study aims to apply and evaluate the teaching methodology known as Problem Based Learning (PBL). PBL) together with Ptable, a web application for the study of the Periodic Table of Elements, seeking to identify possible benefits that this proposal has to offer to the teaching-learning process. The methodology used in the application of the PBL consists of presenting the Periodic Table to students participating in the 9th year B of Elementary School at Nilson Silva School, located in Rolim de Moura/RO, so that, in groups, they can formulate problems in learning the periodic table and later, in groups, present possible solutions. For this, the participants answered two questionnaires with closed questions, one with the objective of getting to know the student and the other to find out how they felt after participating in the research. In addition, participants answered two tests, both with closed-ended questions, in order to compare participants' resourcefulness in relation to traditional TPE versus PTable interactive. The data generated in the research were treated statistically using the chi-square test (X2) to analyze the questionnaires and the Student's t test to determine whether there was a significant difference in the comparison between traditional and interactive tables. A certain adaptation of the referred methodology was observed by most of the participants. Regarding the comparison between the traditional tests versus the Ptable interactive method, there was no significant difference.
