KONSEPSI ALTERNATIF MAHASISWA PADA RANAH MEKANIKA: ANALISIS UNTUK KONSEP IMPETUS DAN KECEPATAN BENDA JATUH
Abstrak: Has conducted
research on student alternative conceptions diagnose concept impetus and
velocity falling objects. Subjects were 73 students of physical education a
public university in South Sumatra. Data collected by the test (18 items of the
Force Concept Inventory), interviews, and observation of learning. From the
results, an alternative conception of the respondents on the impetus in the
form of 1) a moving object has derived impetus from the blow given (59.93 %),
2) objects owned impetus is lost or recovered during the movement of objects
(30.14 %), 3) owned impetus slowly lost objects (40.87 %) , 4) impetus objects
appear some time after the cause no (19.41 %) , and 5) impetus also occurs in a
circular motion (54.11 %); and the speed of falling objects such as heavy
objects fall faster (79.45 %). These results indicate that the respondents have
a strong misconception that the force required to maintain the motion of
objects and the mass or weight of the object affect the speed of a falling
object . It is advisable to carry out the conceptual change theory -based
learning on the subject-matter of mechanics to remediate non - scientific
concepts such .
