Cognitive ability, secondary school students, Bloom’s taxonomy, pH of human skin, Online STEM activity


Cognitive ability of students can be measured by level of questions through bloom taxonomy. This study is to assess secondary school student’s cognitive ability towards the knowledge and understanding of pH of human skin through STEM activity, entitle “pH of Human Skin: Acid or Base?” by asking them to answer 10 items online questionnaires by using Google Form after demonstrated them a mini experiment via Google Meet. 200 students around Malaysia involved in this activity; 49 lower form students, 49 Form 4 students and 122 Form 5 students. Level of item questions based on bloom taxonomy are 50% is remembering (C1), 20% is understanding (C2) and 30% is applying (C3). Based on the results, most of the students which is the lower form, form 4 and form 5 mastering on C1 rather than C2 and C3. They have knowledge and understanding about the pH, acid and base definition since they had study in Form 2. We can conclude that the students can’t relate the theory that studied in the class because of the lack of knowledge and understanding about the application of pH, acid and base in daily life.
