Level of Deep Understanding of Biology Subject Among Fourth grade science students

Abstract

The current research aim to identify the level of deep understanding of biology among students of the fourth scientific grade .The research has been limited to students of the fourth scientific grade in secondary and Preparatory schools in the center of Al-Qadisiyah Governorate for the academic year (2020-2021), and the descriptive survey approach was adopted, and the sample size amounted to (400) male and female students who were chosen randomly. To achieve the objectives of the research, the tow researchers prepared research tool represented by a deep understanding test, which in its final form consisted of (30) paragraphs with (9) article paragraphs and (21) objective paragraphs, according to the definition of (Fahmy, 2008) who classified the skills of deep understanding into (fluency, flexibility, prediction in light of the data, putting hypothesis, making decision, interpretation and asking questions), And has been verified the apparent validity and the validity of the content and validity construction , calculating the difficulty and discrimination coefficients for the test items, and the effectiveness of the wrong alternatives for the objective items. The reliability of the test was also verified by finding the Cronbach's alpha coefficient, which reached (0.896). The research tool were applied in the first semester of the year (2020-2021), and statistical analysis and data processing were carried out using Microsoft Excel and the Statistical Portfolio for Social Sciences (SPSS) program. By applying the T-test equation for one sample to the data obtained from the final application of the research tool, it was concluded that the fourth-grade science students possess a low level of deep understanding of biology. Accordingly, the researcher recommended a number of recommendations and suggestions.
