The Analysis of Concepts Mastery and Critical Thinking Skills on Invertebrate Zoology Course

This study aims to provide an overview of concepts and mastery of critical thinking skills of students in classes taught Invertebrate Zoology conventionally (no or minimal inquiry). Subjects were students of the College of Teacher Training and Education (STKIP) PGRI West Sumatra and Riau Islamic University students (UIR) Department of Biology Education (5th semester and 7th semester), who have taken courses Invertebrate Zoology (on average students take courses Invertebrate Zoology in 3 semesters). Samples were taken randomly as many as 130 people (55 people for critical thinking test consisting of 30 students and 25 students UIR STKIP and 75 people for concept mastery test consisting of 45 students and 30 students UIR STKIP). Mastery of concepts and critical thinking skills of students captured through the test. The results showed that the mastery of concepts and critical thinking skills of students UIR and STKIP PGRI on Invertebrate Zoology some lecture material, which includes 3 phylum (Aschelminthes, Annelids, and Molusca) is still relatively low, ie mastery of concepts and critical thinking skills of students UIR row are 48 and 49, while the mastery of concepts and critical thinking skills of students STKIP PGRI respectively 45 and 49. From these results can also be explained that the concept can not be stored long given in memory of the student , and therefore required the lecture -oriented experience and able to train critical thinking skills of students, the lecture is fitting is the process of inquiry -based laboratory lecture.
