本研究确定了一些替代概念的化学动力学举行的中学和本科生（N = 191）在土耳其。参加的本科生正在学习，毕业后将成为化学教师。学生对化学动力学的概念是通过一系列的书面任务和个别访谈来引出的。中学生表现出的几种另类观念在本科生中持续存在，表明这种另类观念的持续存在。结果表明，学生对热力学和化学平衡的理解不足，对化学动力学概念的理解有很大影响。特别是化学动力学的教学方法的影响进行了讨论。
This study identifies some alternative conceptions of chemical kinetics held by secondary school and undergraduate students (N = 191) in Turkey. Undergraduate students who participated are studying to become chemistry teachers when they graduate. Students’ conceptions about chemical kinetics were elicited through a series of written tasks and individual interviews. Several alternative conceptions exhibited by secondary school students persisted among undergraduates, indicating the persistence of such alternative conceptions. The results suggest that students’ lack of understanding in thermodynamics and chemical equilibrium significantly influences their conceptions about chemical kinetics. Implications for instructional approaches particular to chemical kinetics are discussed.
