Jury simulation research has been the subject of longstanding criticism in regards to ecological validity. One additional factor that has received little attention that may also impact the generalizability of this research relates to excluding participants based on their memory of, or their attention paid to, the case. In order to determine how…

Principals' efforts to support the implementation of interventions involve coordination among multiple actors in their social networks. However, less is known about how distinct features of these social networks are associated with principals' perceptions of the social validity of interventions. In this paper, we used Neal and Neal (Implement Sci…

There are many problems whose solution requires proof that a quadrilateral is cyclic. The main reason for writing this paper is to offer a number of new tools for proving that a particular quadrilateral is cyclic, thus expanding the present knowledge base and ensuring that investigators in mathematics and teachers of mathematics have at their…

Several articles deal with tilings with squares and dominoes on 2-dimensional boards, but only a few on boards in 3-dimensional space. We examine a tiling problem with coloured cubes and bricks on a (2 × 2 × "n")-board in three dimensions. After a short introduction and the definition of breakability we show a way to get the number of…

Researchers need to know what is an appropriate sample size for interview work, but how does one decide upon an acceptable number of people to interview? This question is not relevant to case study work where one would typically interview every member of a case, or in situations where it is both desirable and feasible to interview all target…

The authors add to published empirical findings that an appropriate range of validity evidence for achievement tests, including science and mathematics, has either not been gathered, not reported, or is not accessible for independent review. The current study focuses on a sample of published, peer reviewed science intervention studies from a…

Textbooks currently circulating have not been adapted to online learning systems and their contents are less interactive, less communicative, and have not been based on local content potential. This research aimed to produce digital textbooks based on Madura local content and augmented reality to improve students' scientific reasoning ability.…

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…

A career is a process in which people prepare themselves for a higher level in their professional life by gaining certain experiences and knowledge in their professional life and direct proportion to the increase in their knowledge. Sports are activities that socialize people through certain physical activities, reveal their performance and…

For autism spectrum disorder (ASD) in adults there are several diagnostic instruments available with a need for consideration of the psychometric properties. This study aimed to conduct a first psychometric evaluation of a new diagnostic ASD instrument, the NIDA (Dutch Interview for Diagnostic assessment of ASD in adults) in 90 adult males without…

Background: This paper presents psychometric properties of an instrument for the Assessment of Sexual Behaviour and Knowledge of people with Intellectual Disability (ASBKID), other-reported by professionals who are in daily contact with them. Methods and procedures: Assessments of 236 individuals with intellectual disability were obtained from 100…

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…
