The effectiveness of a proposed strategy according to the Biggs model of the methods of learning in expression performance and the development of the skills of the knowledge of the students in the fifth grade scientific.

The researcher used the descriptive method. He tried to build a suggested strategy according to Bigg’s model for learning techniques, and according to the researcher the experimental design which was known of the partial set as a design for the research. For achieving that, the researcher chose randomly (Asadullah secondary school for boys) which belongs to the general directorate of education of Diyala/ Al Khalis district to be the field of the experiment, the sample of the research is (64) students. The researcher has balanced in variables like (age counted with months, parents’ scientific achievmnets, previous school year marks 2018-2019 at Arabic language and IQ test this year, the post criteria of skills of beyond knowledge) and the researcher defined the scientific material for expression in six expressional topics chosen for fifth class. And the researcher designed (67) cognitive and behavioral objectives from Bloom’s classification for the sixth levels.   The researcher made a lesson plan according to Biggs’ model to teach the students of the experimental group and the controller group who study according to the traditional method. The research first tool was a six serial tests for expressive performance topics, and beyond knowledge skills criteria which consists of (52) item. The experiment continued one complete school term (first course) 2018-2019.  The researcher used the statistical means in the educational bag for spss statistical program version 16, (two independent and paired samples t-test.. At the end of the experiment, the researcher concluded some results are: (Students of the experimental group are better than those of the controller one at the first, second, third, fourth, fifth, and sixth expressive performance for the  experimental group.
