This study aims to develop Nature of Science (NOS) measurement instrument for high school students in the Mathematics and Natural Sciences program using COVID-19 cases that had occurred since the end of 2019. This study also attempts to validate test items with the Rasch model approach. The participants in this study are 194 high school students…

This study was aimed at developing and validating a scale that measures the emotions of secondary school students toward Biology. Before selecting a particular subject, it is very important to measure student's emotions toward that subject. The emotions were measured in two academic contexts: class-related and learning-related situations. The…

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…

K-8 science teacher candidates often struggle with the difficult learning tasks in multiple science courses in their teacher-training program. One of the major parts of these science courses is biology. Student learning in biology depends on their motivational and affective variables as much as their cognitive abilities. As one of the theories of…

This study presents the development and validation of a novel multiple-choice test designed to assess university students' conceptual understanding of electric field, force, and flux. The test of understanding of electric field, force, and flux was constructed based on the results of previous studies using a phenomenographic approach to classify…

A growing body of literature shows that Primary Scientific Literature (PSL) is a valuable and useful tool for STEM. Current assessments measuring the success of PSL-based interventions focus mainly on specific scientific content and/or the specific scientific skills students learn. We believe that the underlying motivation students consider while…

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…

Classical automated test assembly (ATA) methods assume fixed and known coefficients for the constraints and the objective function. This hypothesis is not true for the estimates of item response theory parameters, which are crucial elements in test assembly classical models. To account for uncertainty in ATA, we propose a chance-constrained…

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.…

Research-based multiple-choice questions implemented in class with peer instruction have been shown to be an effective tool for improving students' engagement and learning outcomes. Moreover, multiple-choice questions that are carefully sequenced to build on each other can be particularly helpful for students to develop a systematic understanding…

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…

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…
