Development of electronic activity sheet based preview, question, read, reflect, recite, review (pq4r) learning strategy on ion balance and pH of buffer solution
Jurnal Pendidikan Kimia
The development of a PQ4R-based electronic activity sheet on the material of ion balance and pH of the buffer solution aims to develop a valid electronic activity sheet and determine user responses in learning. The research method used is the research and development (R&D) method by applying a 4-D development model which includes Define, Design, Develop and Disseminate. Pandemic conditions cause research to only be carried out until the Develop stage which was followed by one-on-one trials,doi:10.24114/jpkim.v14i2.34639 fatcat:ktchdcq2szgz3jpsjbyylfsai4
