About Siaw
Profile Description
I am a highly accomplished Mathematics educator, researcher, examiner, and academic leader with extensive experience in Senior High School and tertiary education in Ghana. My professional journey reflects a deep commitment to academic excellence, student development, and curriculum advancement.
My academic research and public engagements have focused significantly on the Van Hiele Geometric Thinking Model among Senior High School students in the Ashanti Region of Ghana. Through conferences, public presentations, and professional discussions, I have contributed to improving the teaching and learning of geometry by promoting structured cognitive development from visualization to formal deductive reasoning. My approach ensures that students understand concepts deeply rather than memorize procedures.
As an experienced examiner for the West African Examinations Council (WAEC), I assess both WASSCE and BECE scripts. I have also served as a Team Leader during WAEC marking sessions, supervising and guiding assistant examiners to ensure accuracy, fairness, and adherence to national marking standards. This role has provided me with exceptional insight into examination requirements, grading principles, common student errors, and techniques that distinguish excellent scripts from average ones. I use this experience to prepare my students strategically for outstanding performance.
I previously served as the Head of the Mathematics Department at Serwaa Nyarko Girls' Senior High School, where I led curriculum planning, teacher supervision, academic mentoring, and departmental performance improvement. Under my leadership, structured lesson planning, assessment analysis, and targeted interventions contributed to measurable academic growth.
My academic qualifications demonstrate both technical depth and pedagogical expertise:
1. HND in Mechanical Engineering – Kumasi Technical University Certificate in 2. Education – University of Education, Winneba
3. BSC Information and communication Technology -University of Ghana
4. BSc Mathematics – Kwame Nkrumah University of Science and Technology
5. MSc Mathematics – University of Cape Coast
6. MPhil Mathematics Education – Kwame Nkrumah University of Science and Technology
In addition to classroom teaching and research, I am an author of Senior High School textbooks in Mathematics and Physics. My books are structured to simplify complex concepts, promote critical thinking, and align with national curriculum standards.
Beyond academics, I possess a strong foundation in music education. I am a church organist with practical experience in keyboard performance and music instruction. I teach basic music theory and keyboard skills, contributing to holistic student development through the integration of arts and discipline.
I combine subject mastery, research-based teaching strategies, examination expertise, leadership experience, and creative talent to produce confident, analytical, and high-performing students. My goal is not only to help learners pass examinations but to cultivate independent thinkers equipped for higher education and lifelong success.
I am committed to excellence, integrity, leadership, and measurable academic impact.

Charles has been my Mathematics tutor in elementary school. He has the patience to take every student through what he is teaching and teaches very well into details for better understanding. He prepared me in Mathematics for the Basic Education Certificate Examination, and I was remarkably among the best students, although I was an average student. He's an amazing teacher!
I wholeheartedly recommend Charles. He is a great tutor. He taught me Physics in high school. He involves students and interacts with them when teaching
I highly recommend Charles as a Mathematics tutor. He helped me prepare for my exams by breaking down complex formulas into clear digestible steps. During our sessions, his patience and structured approach completely changed how I looked at problem -solving. His guidance gave me the confidence to pass my exams with flying colours.
Working with Charles has been an excellent experience. He doesn't just teach the material; he teaches you how to learn effectively.
If you want a tutor who genuinely cares about your progress, Charles is the perfect choice.A math teacher you can trust . He love and understand the math teaching. I got it on first time . Thanks Mr Charles
I am pleased to recommend Mr Charles Siaw for any role involving teaching, mentoring, or student engagement. I have learned a lot under Mr. Charles as a student and I can confidently say that he possesses the qualities needed to inspire trust and confidence in students.
Mr. Charles conducts himself with honesty and fairness in every interaction. Students quickly recognize that he treats everyone with respect and follows through on what he says. This consistency creates a safe environment where students feel valued and heard.
He explains concepts in a way that is accessible without oversimplifying. When students struggle, Mr. Charles remains patient, breaks problems down, and encourages them to keep trying. This approach reduces anxiety and helps students believe in their own ability to learn.
Beyond academics, Mr. Charles takes time to understand students’ challenges and goals. He celebrates small wins and gives constructive feedback that motivates improvement rather than discouragement. Students respond well because they know he is genuinely invested in their success.
Mr. Charles strikes the right balance between being professional and approachable. Students feel comfortable asking questions, sharing difficulties, and seeking guidance, which is critical for building trust in a learning environment.
During my time as a student , I have seen students who were initially hesitant become more engaged, participate actively, and show measurable improvement in both confidence and performance. His presence in the classroom raises the overall tone of respect and motivation.
I have no doubt that Mr Charles will continue to build strong, positive relationships with students and help them develop the confidence to take ownership of their learning. I recommend him without reservation.Am happy to recommend charlse as my mathematics tutor, has a huge passion on that field having worked and thaught students on this arear for nearly two decades helping students to pass their examinations with flying colours.
One of the finest and classic tutor with years of experience. A top notch, for that matter.View more recommendations
