Which Country is More Effective in Science Teaching? Evidence from PISA 2015 - A descriptive study using secondary school assessment data

Oct 15, 2026

Uploaded by Mimi

This study determines how effectively different countries use educational inputs in the science education process at the secondary level. Using a descriptive model and data drawn from the PISA 2015 dataset, the analysis compares results across 70 countries, including Turkey. Educational inputs are grouped into training inputs and training outputs, while student science achievements are used to identify which countries manage these inputs more effectively. Turkey’s effectiveness in science teaching is evaluated relative to nearby countries, and recommendations are proposed to improve secondary science education outcomes.

The study is in the descriptive model and the data is derived from the PISA 2015 data set, which provides information to countries on secondary education programs. Data from 70 countries, including Turkey, were used in the study. The effectiveness of Turkey in the process of science teaching in secondary education has been compared with other countries and suggestions have been made to increase the effectiveness of secondary education teaching. The data for this study are grouped into training inputs and training outputs. Student behaviour hindering learning”, “teacher behaviour hindering learning”, “shortage of educational material”, “shortage of educational staff”, “professional development”, “teachers participation”, “curricular development”, “total number of science teachers at school”, “index science-specific resources (sum)” were defined as the educational inputs. The science achievements of students have been taken into account in determining which countries have more effective management of educational inputs accepted in this study. Secondary scholl level education inputs while nearby countries respectively to use effectively Slovakia (97.30%), Slovenia (91.16%), Brazil (90.50%), Turkey (89.75%), Finland (84.65%), Greece (83.31%), Denmark ( 83.25%), and Czech Republic (80.61%) . education outcomes in Turkey is ranked as 20th in science teaching secrets to use it effectively.
