Effectiveness of Ecology and Environment Textbook Based on Science Literacy and North Sumatra's Local Potency to Improve High School Student Science Literacy

This study was held to determined: 1) Effectiveness
of learning by using Ecology and environment textbook based on
science literacy and local potency of North Sumatra in ten grade
of Markus High School and Free Methodist High School. (2) Ten
grader student’s science literacy after using ecology and
environment textbook based on science literacy and North
Sumatra's local potency and students using textbooks in Markus
High School and Free Methodist High School. This research was
quasi experiment with two class served as sample which taken by
cluster random sampling. The first class (X-1) was taught by using
student biology handbook and the other class (X-1) was taught by
using ecology and environment textbook based on science literacy
and North Sumatra's local potency. The instrument used was
science literacy test which contain an essay test, multiple choices
test and observation sheet. Data analysis technique was by t test
at significant level of α = 0,05, using SPSS 22.0. The result
showed there was a significant effectiveness differences in class
taught by using ecology and environment textbook based on
science literacy and North Sumatra's local potency (N-gain =
0,65, and ± SD = 79,86 ± 4,21) with the class taught by using
student’s original biology handbook (N-gain = 0,4, and ( ± SD =
68,01 ± 5,71) and t test result obtained was tcount = 10,456; P =
0,00. As a follow up this result, it is suggested that teacher used
this ecology and environment textbook based on science literacy
and North Sumatra's local potency as an effort in improving
student’s science literacy
