تنمية النزعة المنتجة في الرياضيات باستخدام الأنشطة القائمة على مدخل stem لدى تلاميذ الصف الخامس الإبتدائي
The aim of this research is to identify the effectiveness of using activities based on the multidisciplinary STEM approach in developing the productive tendency in mathematics among the fifth-grade students. The research was applied to a group of fifth grade primary students, which amounted to (34) male and female pupils, at the Nile International School, Damietta branch (NEIS schools), and divided into (17) male and female pupils in an experimental group and (17) male and female pupils in a control group. The present research prepared the following instructional materials: a list of the skills of the productive tendency, and the student's book in units (Coordinates and transformations), (Mental methods and calculator use), (Preparing for algebra), which are prescribed to the fifth grade students in the second semester 2021-2022 after reformulation According to the activities based on the STEM approach, the teacher's guide to teaching units using the activities based on the STEM approach, and the research tool was the productive tendency scale. This research revealed the following result: the effectiveness of using activities based on the STEM approach in developing the productive tendency of the fifth-grade students. (Published abstract)
