The Effect of Using the Integration Approach between Science and Plastic Arts on Science Achievement and the Development of Science Process skills among 5th Grade Basic Education Female Students. This study aimed to investigate the impact of using the Integration Approach between Science and Plastic Art on Science Achievement and the development of Science Process skills among 5th Grade Basic Education Female Students. The sample consisted of (58) female students selected from AlYaqeen Basic Education (5-10) in South Al-Batinah Governorate. The sample was divided into two groups; experimental group (N=29) taught the science content by the integration approach between science and plastic art and control group (N=29) taught the science content by the conventional method of teaching. The study lasted for eight weeks in the second semester of the academic year 2011/2012. To achieve the study's aim, three research instruments were designed: teacher guide in the integration approach between science and plastic art for experimental group, science achievement test and science process skills which included observation, classifying interpretation, communication and inferring. The reliability of the achievement test was (0.89), whereas the reliability of science process test was (0.92). The result revealed that there were no statically significant differences in science achievement at (a=0.05) between the experimental group students and the control group students. However, there were statically significant differences at (a=0.05) between the two groups in acquiring science process skills in classifying and communicating skills and the whole process skills test in favour of the experimental group. The study also showed that there were statically considerable differences at (a=0.05) between pre and post process skills test in observation, classifying, communication and in the whole test in favour of the experimental group. Accordingly, the study proposed the need for conducting workshops and training courses for science teachers on how to use the integration approach between science and plastic art in teaching science. It also recommended conducting similar studies of the current study, but on other variables such as creative thinking, and the trend towards the study of science and arts.
