IDENTIFIKASI MISKONSEPSI SISWA SMA PADA KONSEP FAKTOR-FAKTOR YANG MEMPENGARUHI LAJU REAKSI
ABSTRACT: This research aimed
to identify misconception of senior high school students class XI in SMAN 1
Lhokseumawe in learning concept of factors that affect chemical reaction rate.
The instrument used in this research was 20 multiple choice questions with
reasons and equipped by CRI (Certainty of Response Index) which is used to
measure the degree of certainty of students’ answers. There were 38 students as
respondents in this research. The data shown that 13,16% of students held
misconceptions relating to the effect of surface area on rates of reaction,
57,89% students held misconceptions relating to the effect of catalyst on rates
of reaction, 57,89% students held misconceptions relating to the effect of
temperature on rates of reaction, However there none of students misunderstood
about the effect of reactant concentration and pressure to chemical reaction rate and most of them
understood about the collision theory.
