This study aimed to develop an instrument with acceptable validity and reliability for assessing two key aspects among science teachers: their self-efficacy in teaching science through an integrated STEM approach (STSIS) and their outcome expectancy when employing this approach (OETSIS), which we refer to as TSTSIS. We administered this tool to…

A major challenge to promoting effective early science and engineering education is the lack of reliable and validated assessments that align with current educational guidelines for science and engineering. Existing early science and engineering assessments either cover a narrow range of concepts and practices and/or are not designed in a way to…

The aim of this study is to develop a valid and reliable achievement test on the subject of 'Basic Compounds in the Structure of Living Things'. During the preparation of the draft form of the test, a 32 item-question pool was created by the researchers in the light of the relevant literature. Then, these questions were presented to expert opinion…

In this study, we aimed to develop an instrument that could be used to measure students' achievement in modern physics at high school level in a valid and reliable manner. The study was carried out in fall 2013-2014 with a total of 304 students. In this study, expert opinions were obtained to determine the test's content validity. The reliability…

Chemistry education research has increasingly considered the role of affect when investigating chemistry learning environments over the past decade. Despite its popularity in educational spheres, mindset has been understudied from a chemistry-specific perspective. Mindset encompasses one's beliefs about the ability to change intelligence with…

Self-efficacy scales have been used widely across curriculum and demographic structures, while retaining their objectivity in a specific domain. This pilot study aimed to test the validity and reliability of adapted scales that incorporated four sources of self-efficacy (mastery experiences, vicarious experiences, social persuasion, and emotional…

Scientific inquiry ability is closely related to the process of hands-on inquiry practice. However, its assessment is often separated from this practice due to the limitation of technical basis and labor cost. The development of multimodal data analysis provides a new opportunity to realize automated assessment based on hands-on practice.…

Children interact with science from the moment of their birth. By means of the scientific experiences they have as a result of this interaction, children acquire numerous skills related to science at the early ages. These scientific skills and children's orientation towards science such as awareness, attitude, proficiency, inquisitiveness, as well…

Attitudes towards learning chemistry have been little studied in secondary school students, especially regarding dimensions related to problem solving, the molecular atomic perspective of chemistry, and real-world connection of chemistry. In the present study, we first aimed to design and assess the psychometric properties of the attitude to…

In this study, a valid and reliable multiple-choice achievement test has been developed in order to measure the academic achievement of 8th grade students about the units of "States of Matter and Heat" and "Electricity in Our Life". The pilot study of the achievement test was carried out with 30 questions which were prepared…

In this study, the Integrated Scale of Technology Use in Physics (ISTUP) was developed to determine students' frequency of technology use, their perceptions about the effects of technology use on physics interest and achievement, and their preferences of technological tools and applications in learning physics. The scale was administered two…

We describe the development, validation, and use of the "Learning Progression-Based Assessment of Modern Genetics" (LPA-MG) in a high school biology context. Items were constructed based on a current learning progression framework for genetics (Shea & Duncan, 2013; Todd & Kenyon, 2015). The 34-item instrument, which was tied to…

This study aims to reveal (1) the construct and (2) the characteristics of the developed instrument for assessing Physics cognitive learning achievement of high school students in outdoor learning models through local wisdom-based fieldwork. This research was a research and development using the approach developed by Mardapi (2012: 110). The steps…

Background: The importance of valid and reliable instruments for the assessment of factors affecting students' interest in science encouraged the development and validation of a brief Spanish instrument for the measurement of expectancies of success in school science, named SUCCESS. In this study, the psychometric properties of the SUCCESS…

This study describes the impact of embedding dynamic computer visualization (DCV) in an online instrument that was designed to assess students' understanding of osmosis. The randomized posttest-only control group research was designed to compare the effect and the perceived helpfulness of the integration of DCV before and after the administration…
