FUTURE WORK Q&A
We intend to introduce the WiMVT We sincerely welcome your questions,
system into real classrooms practices in comments, and suggestions
secondary schools in Singapore. We will
do both the curriculum design for students
and profession development for teachers
where inquiry learning works within
several subjects in science (physics,
chemistry and biology). (hopefully, the
system can also be appropriate for
primary science learning)
