Impact of a Teaching Strategy According to Nardo's Developed Model of Algebraic Thinking in Middle School Students

The objective of the research is to know the impact of a teaching strategy according to the Nardo's developed model of algebraic thinking among middle second graders and to achieve the research objective the two researchers selected divisions of (a, b) From (Mediterranean Zayn al-Abidin -A - Boys) of Baghdad/Karakh Education Directorate II for the academic year (2023-2024) The Division (a) represents the control group and includes (31) students who have studied in the usual manner, and a Division (b) The pilot group included (33) students studied according to the teaching strategy according to the Nardo developer model, and the two groups were rewarded (Control and experimental) in variables (pre-year attainment (2022-2023), previous knowledge in mathematics, intelligence) The researchers built the research tool with a algebraic thinking test in mathematics and included (33) Objective paragraph (multiple choice), verified its honesty and consistency as well as Cychometric properties. Results analysed using statistical means. After the duration of the trial, the test tool applied to the two groups (Experimental and control) The results showed that the students of the experimental group outperformed the students of the control group in the algebraic thinking test.
