The objectives of the research were: 1) to develop the lesson plans for "Weight and Measurement" of Mathematics by using Problem-Based Learning on TPACK MODEL based on the efficiency of the process and the overall result (E1/E2) at the established criteria of 75/75; 2) to compare the students' learning achievement in "Weight and…

Young children can struggle to learn difficult disciplinary content and important skills for practicing science. Problem-based learning (PBL) may be useful for addressing such difficulties, yet evidence to support its usefulness in elementary school-aged children is limited. We considered the role of a PBL unit in improving students' genetics…

This study explores the integration of culturally responsive mathematical modeling (CRMM) in primary grades to promote racial justice and critical consciousness. The research focuses on how CRMM can support problem-based learning (PBL) by engaging students in analyzing real-world issues through mathematics. CRMM leverages students' cultural…

Communicating their thinking in mathematics is challenging for young children. This research studied the change in six-year old students' oral and written solution explanations before and after six problem-based mathematics lessons that focused on developing conceptual understanding of adding or subtracting a 2-digit number and a multiple of ten.…

The main objective of the study reported was to explore the effect on young children's critical thinking of a peer-tutoring training embedded with the metacognitive processes required for problem-based learning and, consequently, for critical thinking. The sample consisted of 90 first- and third-grade pupils (45 pairs) randomly assigned to the…
