This study aimed at identifying the level of scientific argumentation skills in chemistry subject among Omani Grade 11th students and the effects of their logical thinking skills and gender on this level. The study sample consisted of (400) male and female students selected purposely from one educational region in Oman. The study’s instruments consisted of “Scientific Argumentation Skills Test” and “Logical Thinking Test.” The study results revealed that the level of grade 11th students was moderate in argumentation skills and was low in logical thinking. In addition, there were statistically significant differences at (ρ < 0.05) in scientific argumentation skills level due to gender in favor of female students. It also showed significant differences in logical thinking variable in favor of students with abstract thinking, and in the interaction between gender and logical thinking in argumentation level in favor of female abstract thinking. The study is important for Omani chemistry teachers because it gives an overview of the level of scientific argumentation skills and logical thinking skills among their students, which then helps the teachers in determining the next steps of the learning process by adopting appropriate teaching strategies.

This study aimed to identify the aspects of reading impairment ‎among cycle one pupils at private schools in the Sultanate of Oman ‎from their teacher's perspective and discover statistically significant ‎differences in cycle one teacher's responses in those schools attributed ‎to the governorate variable.‎ In order to achieve the study's goal, the researchers used the ‎descriptive method. The survey population included all cycle one ‎teachers in private schools from governorate of Al-Batinah South and ‎North, Muscat and Al-Dakhiliyah. Responses of 500 teachers were ‎received from those governorates. At the same time, among those ‎teachers about 150 teachers were chosen randomly. They represent ‎‎30% to be the purposive sample. The researchers started to use a ‎questionnaire to measure the degree of popularity of the aspects of ‎reading impairment among cycle one pupils at private schools in the ‎Sultanate Of Oman. This questionnaire is divided into three categories ‎related to reading letters, words, and sentences. ‎ It was revealed that the degree of popularity of the aspects of ‎reading impairment among cycle one pupils at private schools in the ‎Sultanate Of Oman from the cycle one teacher's perspective came to ‎an average degree. However, there are no statistically significant ‎differences at the level (0.05) among the teachers' responses according ‎to governorate variable. ‎ According to the study result, it is recommended to put more ‎efforts in teaching reading skills in order to eradicate the common ‎aspects of reading impairment. Related to these recommendations, it ‎is suggested that conducting pilot studies aimed at testing proposed ‎programs are required to find out their effects to solve challenges ‎resulted from aspects of reading impairment among cycle one pupils ‎at private schools in the Sultanate Of Oman‎.
