The POE tasks also revealed that some of the students had misconceptions regarding pH and pOH. The students believed that pH was a measurement of the acidity, while pOH was a measurement of the basicity. The findings obtained have certain implications for the secondary chemistry program. 展开 ...
The purpose of this study was to investigate the effects on students' achievement and misconceptions of new teaching material developed for the unit 'acids and bases". Also, the students' attitudes towards chemistry were explored. The ne... Gkhan Demircioglu,A Ayas,H Demircioglu - 《Chem.educ...
We also learned how to represent a covalent substance using dot-and-cross diagram and structural formula. The topic of covalent bonds has been written keeping in mind the syllabus of Secondary 3 Chemistry students. Practise the examples and questions given in the article to get a better ...
