Interdisciplinary thinking is critical for equipping students to apply scientific knowledge and tackle societal challenges across various disciplines, which has been recognized as a key objective of twenty-first century science education. However, research on effective interdisciplinary assessment in secondary school science education is still…

Principal instructional leadership (PIL) refers to the management of school curriculum, instruction, and assessment by the principal of a school. It is essential to measure the extent of the instructional leadership provided by principals and to propose means of improving instructional leadership. The principal instructional leadership scale…

The problem of local item dependencies (LIDs) is very common in personality and attitude measures, particularly in those that measure narrow-bandwidth dimensions. At the structural level, these dependencies can be modeled by using extended factor analytic (FA) solutions that include correlated residuals. However, the effects that LIDs have on the…

This study aimed to develop a valid and reliable multiple-choice achievement test for the subject area of ecology. The study was conducted within the framework of exploratory sequential design based on mixed research methods, and the study group consisted of a total of 250 middle school students studying at the sixth and seventh grade level. In…

Self-regulation skill is the ability of an individual to plan, monitor, evaluate, and modify their learning process when necessary. It is highly important in foreign language learning because learning a language requires long-term motivation, discipline, and a strategic approach. This study aims to determine the level of high school students' use…

Parents' anxiety about their children's education has been common in recent years and has a negative effect on children. This study aimed to clarify this construct and develop the Parental Anxiety about Children's Education Scale (PACES) to lay a foundation for future research. In Study 1, we developed a scale based on 465 parents that included 20…

In this study, it was aimed to develop an achievement test taking into account the subject acquisitions of the sound and properties unit in the sixth-grade science course. In the test development phase, firstly, literature review for the study was conducted. Then, 30 multiple choice questions in align with the subject acquisition in the 2018…

The present study has aimed to develop and validate a protein concept inventory (PCI) consisting of 25 multiple-choice (MC) questions to assess students' understanding of protein, which is a fundamental concept across different biology disciplines. The development process of the PCI involved a literature review to identify protein-related content,…

Assessing students' multicultural self-efficacy was a challenging duty for high school counselors, particularly in conjunction with the understanding function of school counseling. The main objective of this development research was to design and validate a scale for measuring the multicultural self-efficacy of high school students. The 851 public…

Trigonometry is an important part of secondary school mathematics, but it is usually challenging for students to understand and learn. Since trigonometry is learned and used at a university level in many fields, like physics or geodesy, it is important to have an insight into students' trigonometry knowledge before the beginning of the university…

PISA (Program for International Student Assessment) tests have enabled the OECD countries to see not only the success of their students in gaining the ability to solve some daily problems they may encounter in their lives but also the place in the world rankings as a result of an objective evaluation comparing the achievement results of…

The development of assessments as part of the funded LOCUS project is described. The assessments measure students' conceptual understanding of statistics as outlined in the GAISE PreK-12 Framework. Results are reported from a large-scale administration to 3,430 students in grades 6 through 12 in the United States. Items were designed to assess…

The accurate assessment of analytical thinking in physics, particularly in magnetism, poses substantial challenges due to the limitations of conventional tools in measuring higher-order cognitive skills. This study aimed to validate an analytical skills test in physics, based on Bloom's Revised Taxonomy, with an emphasis on the dimensions of…

Active learning (AL) techniques invite students to participate actively, either physically or mentally, in the learning process so that they can change their behavior efficiently to achieve great achievement. Still, there is insufficient knowledge concerning the dimensions of AL techniques for business subjects of secondary school students in…

This research aimed to develop a valid and reliable test to be used to detect sixth grade students' misconceptions and errors regarding the subject of fractions. A misconception diagnostic test has been developed that includes the concept of fractions, different representations of fractions, ordering and comparing fractions, equivalence of…
