A Study of Aboriginal and Urban Junior High School Students’ Alternative Conceptions on the Definition of Respiration
Type: Empirical
Data collection method: Survey
Number of subjects, range: Large — 31 or more
Grade and age of subjects: 6th-8th grade — under 13-14 years, 9th-12 grade — under 17-18 years
- Microorganisms do not have respiratory organs, such as lungs or tracheas, so they cannot perform respiration.
- Oxygen is the raw material needed to produce blood.
- The brain needs oxygen because it controls our body activities.
- As long as trees photosynthesize, they can live because photosynthesis can replace respiration.
- If there is storage of nutrition when the leaves have been shed, trees can live without respiration.
- Energy can be given to the stems from the sites of photosynthesis.
- The function of stems is transportation, thus stems are unable to perform respiration.
- Plants require O2 at night because during this time they are unable to photosynthesize.
- O2 can promote breathing and the exhalation of CO2.
- O2 is one kind of nutrition and can help development.
- O2 can promote breathing and the exhalation of CO2.
- Plants need O2 to produce nutrition at night.
- O2 can be used as a raw material in photosynthesis.
