The aim of this study was to investigate about the study skills which are mostly practiced by (PTUK), freshmen and sophomores, Arabic-speaking students who are learning English language introductory courses, namely, Remedial English (no.15200099), English (1)- (no.15200106), and English (2)- (no.15200112). This study also aimed at investigating about the relationship between the mostly practiced study skills and the independent variables of (sex) and (College). To achieve the purpose of this study, the researchers built a 5- domain questionnaire with (30) items which was basically based on related literature; it was refereed and then was adapted and developed to correspond with the questions of the study and the learning environment of the PTUK. The questionnaire was distributed to a sample of (340) female and male students representing colleges and different specialization of PTUK with a percentage of (percent 30) out of the total of (1122) female and male students representing the whole population of the study consisted of. Results of this study indicate that the domain of " Scheduling and time management " was the first and the highest in level with a Mean of (3.53) and with a Standard Deviation of (0.75); the first and the highest practiced skill within this domain was item no. (1) " I attend lectures without any delay" with a Mean of (4.16) and a Standard deviation of (0.89); the least practiced skill within the domain of "Motivation and attitude" with a high degree was number (22), "During the lecture, I am wakeful, active, and interested in dealing with the information presented." with a Mean of (3.49) and a Standard deviation of (1.02). Results of this study also indicate that there are no statistical differences related to the variables of (sex) and (College). In accordance with the findings and results of this study, the researchers recommend that PTUK should offer more guidance and help to its freshmen and sophomore's students, who are learning English language introductory courses, through crediting a separate course of "study Skills" which can orient and help students anchor their study pursuit with an ultimate goal of being independent learners. The researchers also recommend carrying out further related studies in other universities in Palestine.
