A proposed conception to include the standards of earth and space sciences in the science curriculum at the preparatory stage and its effectiveness in achieving some educational goals for students

The aim of the research is to include earth and space sciences standards into science curriculum at the preparatory stage; due to the insufficient of science curriculum in this field. This to keep pace with contemporary international standards of the age of knowledge and the twenty-first century education. It also aimed to measure the effectiveness of the proposed curriculum in achieving some educational goals for students. The research based on the descriptive analytical method to describe the proposed standards, and to analyze the science courses of the three grades using the content analysis tool. As well as describing the proposed curriculum and its elements, and the educational objectives targeted from it. A unit of study titled "Satellite Technology" was applied on a group of students of first grade (32) using the quasi-experimental method by one group and the results of pre and post-test of the targeted educational goals. The results of the descriptive study came to show that the percentage of verification of the standards of earth and space sciences in the preparatory stage (20.6%), which is low; and the percentage of verification came in the first preparatory grade (25.2%), and the second preparatory grade (25.2) %), And the third preparatory grade (20.6%). The result of the standards came as follows: the universe standard (4%), the “earth” standard (8.9%), the weather and climate standard (2.1%), and the space technology standard (zero).The results showed the differences between the pre and post-test of the educational goals. The effectiveness of the curriculum in achieving the targeted cognitive goals (understanding - application - analysis), and skills goals (reading satellite images, and interpreting satellite images) for the first grade students, where measured by using the Black ratio and came (1.6), which indicates a high level of effectiveness of the proposed curriculum.
