The current qualitative study was conducted to analyze the mathematics curriculum across grade levels for students’ critical thinking skills development. Qualitative content analysis was used to analyze the document with the facilitation of NVivo software. As per the analysis, Grades I-III cover core math concepts at an introductory level using real-life examples presented concretely. Then grades IV-VIII revisit these same ideas with more depth and add logical reasoning. Finally (IX-X) and higher secondary (XI-XII) levels aim to build a rigorous conceptual understanding of complex mathematical topics like calculus, vectors, and complex numbers as well as non-routine problem-solving capacity utilizing proof techniques and technology tools like MAPLE software. The research results show that the curriculum is indeed effective for 21st-century skills development such as critical thinking, problem-solving, and technological literacy. Students who complete this systematic program will be prepared for advanced studies or careers that require mathematical proficiency.

Blackboard is an Internet teaching management platform that allows a virtual learning environment via the Internet. It is the most popular system used by universities and educational institutions worldwide. However, this study is more concerned with foreign language (EFL) students' perceptions of the use of Blackboard in their courses. For this reason, we focused on 100 EFL students as respondents to the online questionnaire who attended the Language Department-College of Science and Humanities at Rumaah-Majmmah University in this research. Whereas, findings from both the survey data were analyzed by using (the SPSS Program) with the Lickert scale method showed participants had positive perceptions of the use of Blackboard technology for educational purposes. The results of students' perceptions proved the usefulness of Blackboard technology in the field of education. Hence, the suggestions of this study could be shared with other educational institutions in the kingdom.
