Research Objectives 
The research design uses quantitative research. According to Sugiyono (2017:14) quantitative research is defined as 
research based on the philosophy of positivism, which is used to examine certain populations or samples, sampling 
techniques are generally carried out randomly, data collection uses research instruments, data analysis is 
quantitative/statistical with the purpose of testing the established hypothesis. This study aims to determine whether the 
guided inquiry learning model assisted by puzzle media can improve student learning outcomes in science subjects in 
grade 5 elementary school material for human respiratory organs. The method used is an experimental method to find the 
effect of treatment on others under controlled conditions. The design used in this study is a pre-test post-test control group 
design. 
2. 
Methodology 
This type of research uses quantitative research. The research design used in this study was a non-equivalent control 
group design (pretest-posttest control group design without random). The research subjects were all fifth-grade 
elementary school students in the Sudirman Cluster, Pulokulon District, Grobogan Regency. The population in this study 
were all fifth-grade students of the Sudirman Group, Pulokulon District in 2021 totaling 10 elementary schools with a 
total of 257 students. The sample in this study were two elementary schools, namely class V Public Primary School 
Number 4 Karangharjo as a Guided Inquiry Learning class assisted by Media Puzzle and class V Public Primary School 
Karangharjo as the control class. The sampling technique is purposive sampling. 
The research variable is the guided inquiry model with the help of the puzzle picture as the independent variable 
and the fifth-grade students' learning outcomes as the dependent variable. Data collection techniques used are observation 
and written test. The research instrument was a multiple-choice test with 20 questions. The data analysis includes data 
description, analysis prerequisite test, and hypothesis testing using t test. and N-gain test.
