الملخص EN

The current research aimed to investigate the effectiveness of “safe driving” program in the light of the STEM approach in developing secondary school students’ strands of mathematical proficiency.

to achieve this objective, a group of second grade secondary male and female students (n = 32) in Bakour secondary co-ed school, affiliated to Abou-Teig educational directorate, Assiut governorate, Arab republic of Egypt.

a theoretical framework was developed, while addressing STEM approach and mathematical proficiency, the following research instruments were developed : a questionnaire to define the rules for program development, and a matrix including topics of the proposed program.

in the light of that, the proposed STEM-based program was developed including student’s workbook, teacher’s manual on how to teach the content of the program, and the measurement instruments to measure the intended learning outcomes (ILOs) including, mathematical proficiency test, and a scale of productive mathematical tendency.

the results indicated the effectiveness of the STEM-based program in developing secondary school students’ strands of mathematical proficiency, with a significant difference at (0.01) level between the mean scores of the research group of the pre-post measurements of the mathematical proficiency test, in favor of the post-measurement.

t-value was (55.86) which is a statistically significant value at (0.01) significance level.

effect size was (0.990), using eta square equation.

the results also proved that the program is effective in developing the productive mathematical disposition of the sample students.

there is also a significance difference at (0.01) level between the mean scores of the research group subjects on the pre-post measurements of the productive mathematical disposition scale, in favor of the post-measurement, with a t-value of (36.48) which is a statistically significant value at (0.01) level of significance, with eta square reaching (0.977).
