Abstract

This study aimed to identify readability level of computer science textbooks among the Jordanian eleventh grade students. A cross-sectional, descriptive study was conducted. The study population consisted of all eleventh graders of Al-Mafraq education directorate. The study sample comprised 122 male and female eleventh graders, chosen by intended sampling method from two public schools. However, to answer the research questions, the researchers prepared a close test as an instrument to measure the readability levels using three randomly selected texts, which have never been used, from eleventh grade computer science textbook. After validating the instrument, it was administered to the study participants. The following results were reported: Eleventh grade computer science textbook readability levels were classified based on the scores students attained during the test as follows: the independent level of readability (48.9%), followed by depressed level (35.1%) and finally the educational level with (16.1%); the existence of positive statistically significant relationship at (α≤ 0.05) level between student achievement in computer subject and its readability level; there were statistically significant differences at (α≤ 0.05) level; the eleventh computer sciences textbook readability levels attributable to student's gender, is in favor of females. Based on these results, some recommendations were suggested.

Key words: Readability, computer sciences textbook, eleventh grade.
