Measurement of Science Literacy Skills of Elementary School Teacher Education Students: Development and Validity Testing of Assessment Instruments

/in /by

This study aims to develop and test the validity and reliability of a scientific literacy instrument for students of the Elementary School Teacher Education (PGSD) Program. The instrument was designed to measure three dimensions of scientific literacy: content knowledge, procedural knowledge, and epistemic knowledge, focusing on Earth and Space Science topics. A total of 18 questions were constructed based on indicators that assess the ability to explain scientific phenomena, evaluate scientific investigations, and interpret scientific data. The instrument was tested on 33 PGSD students at Universitas Sebelas Maret (UNS) and analyzed using the Content Validity Index (CVI) and reliability tests via SPSS software.

The results indicated that most items were valid, with an S-CVI/Ave value of 0.981 and an S-CVI/UA value of 0.8333. However, one item was found invalid with an I-CVI score of 0.67. The reliability test showed that some questions had a good level of reliability, while others required revision due to low reliability. Additionally, analysis using the Item Response Theory (IRT) revealed that the questions varied in difficulty and discrimination, with most questions having positive discrimination values and a range of difficulty levels. Overall, the instrument was found to be valid and reliable for assessing the scientific literacy of PGSD students, although some questions need revision to improve consistency and accuracy.
