When teachers have a practical, easy to use tool to self-assess acts of teacher leadership, they are better equipped to develop as leaders by self-determining to whom or what they are committed (relatedness), what they know and can do (competence), and when and how to act (autonomy). The purpose of this mixed methods study was to assess the…

Background and Context: Despite the increasing implementation of coding in early curricula, there are few valid and reliable assessments of coding abilities for young children. This impedes studying learning outcomes and the development and evaluation of curricula. Objective: Developing and validating a new instrument for assessing young…

In the current study, we aimed to develop a reliable and valid scale to address individual cognitive load types. Existing scale development studies involved limited number of items without adequate convergent, discriminant and criterion validity checks. Through a multistep correlational study, we proposed a three-factor scale with 13 items to…

Supporting teachers professionally, both in their teaching skills and the inclusion of technology, is one of the few direct interventions to help them grow. Currently, few instruments assessing these perceptions exist, and evidence on their validity is sparse. Hence, this paper presents the development and validation of an instrument assessing…

To date, the Intentions to Seek Counseling Inventory (ISCI) is the most widely used instrument to measure psychological help-seeking intentions. However, the ISCI is yet to be validated with international students. In this study, we examine the dimensionality and reliability of the ISCI by performing exploratory factor analysis, Cronbach alpha…

Previous research has shown that question characteristics, such as the shape of rating scales, can affect how respondents interpret and respond to questions. For example, earlier studies reported different response distributions for questions employing rating scales in the form of a ladder and in the form of a pyramid. The current experiment,…

Self-determination can affect students to have a positive way of thinking and acting, also to make realistic choices so they can make a decision responsibly. This study aimed to develop a questionnaire to measure student self-determination and validate it. This study was conducted in 2019, involved 406 university students as participants…

Windmill images and shapes have a long history in geometry and can be found in problems in different mathematical contexts. In this paper, we share and discuss various problems involving windmill shapes and solutions from geometry, algebra, to elementary number theory. These problems can be used, separately or together, for students to explore…

In this paper, Harel and Sowder's proof schemes of taxonomy were applied for identifying eighth grade students' learning of proof and proofing. This study aimed to examine what kind of proof schemes are used in geometry and measurement learning areas and student's skills in giving proof and their opinions about proof. Qualitative methods were…

This article describes the development of an instrument for examining schools as institutions where teaching practices and school structures provide opportunities and support for student imagination, creativity, and innovation, as well as initial comparisons using the instrument, using a sample of n = 5020 students and n = 268 teachers (n = 161…
