الملخص EN

The study aimed to investigate the effectiveness of a unit developed in light of the integrated STEM approach in developing some 21^stcentury skills among sixth-grade primary pupils.

The researcher developed the unit of geometry and Measurement unit that six grade primary pupils taught in the first semester.

A list of 21^stcentury skills was prepared to identify the skills required for six grade primary pupils.

A teacher guide and student book for the developed unit was prepared.

The researcher measured the 21^stcentury skills through preparing a higher mental skills test (critical thinking skills and problem-solving skills), and preparing skills scale (social, personal, creative and digital) to measure the rest of the skills on the list.

The participants of the study consisted of seventy-one ( N= 70) pupils in one of the schools from Qalubia Governorate, Toukh Educational Administration.

They were divided into an experimental group ( N= 35) and a control group ( N=35).

Both groups are equivalent.

The test and the scale were applied before and after teaching the unit, in the first semester 2019-2020, The results of the study revealed the superiority of the experimental group over the control group in the 21^stcentury skills as a whole, and each sub-skill through statistically significant differences at the level (0.01).

The size of effect of the unit in developing the skills of 21^st century skills as a whole and each sub-skill was calculated and it was significant in favor of the experimental group.
