Research is a concrete action in academia which has uplifted societies' prosperity. Although researchers have given particular attention to student perceptions about what research is in a higher education context, little attention has been given to secondary school students' perceptions about this issue. To fill this gap, Yeoman et al. (2016)…

The concept of collective efficacy that can be defined as "a belief in their common ability to organize and realize plans to achieve goals" (Bandura, 1997, p. 477) has gained utmost importance in educational contexts. Therefore, there arises an emergent need to develop scales to evaluate teachers' collective efficacy behaviours. To this…

Test development is a complicated process that demands examining various factors, one of them being writing items of varying difficulty. It is important to use items of a different range of difficulty to ensure that the test results accurately indicate the test-taker's abilities. Therefore, the factors affecting item difficulty should be defined,…

Understanding motivational beliefs such as expectancy and value that shape students' persistence and decision to pursue a STEM career, obtaining valid and reliable measures for these dimensions, and developing strategies using this data are critically important to ensure students' persistence in the STEM pipeline. Therefore, this study aims to…

This study aims to develop and test the reliability and validity of a multiitem teachers' perceived presenteeism behavior scale. For this, first of all, a semistructured interview form was applied to 57 teachers, an item pool was formed for the presenteeism scale with the data obtained, and the draft form of the scale was prepared in line with the…

Informed study decisions are pivotal for student retention in higher online education. A self-assessment prior to enrolment has been proposed as a promising approach to enable informed decision-making and to build resources for retention. To determine whether such a self-assessment affects the decision-making process as intended, thorough and…

This study was conducted to develop a valid and reliable measurement tool that can identify middle school students' self-regulation skills. Firstly, the literature was utilized in the development of the measurement tool. The form was finalized with the support of the opinions of different experts and a trial application. Then, the form was…

This study aims to develop a 'Teacher Expectation Scale' (TES) to accurately and reliably measure teachers' expectations from their students. The development process of TES has an exploratory mixed method research design. The maximum variety sampling method was used when collecting qualitative data for the study, and the simple random sampling…

This study introduces the Professional Development Evaluation Scale (ProDES), a tool that has been developed to evaluate the impact of professional development as it relates to participants' Learning and Use of New Knowledge and Skills, Organisational Support, Student Learning Outcomes, and reactions.
