In this cross-national study, we explore the different ways of reasoning-and-proving (RP) presented in three 8th grade textbooks, one from each country: Turkey, Norway, and Slovakia. While the analysis revealed that all three textbooks contain similar numbers of problems involving some form of RP, differences exist in terms of the dominating ways…

Students' difficulties with proofs are well documented. To remedy this, it is often recommended that reasoning and proving be focused on in all grades and content areas of school mathematics. However, proofs continue to have a marginal place in many classrooms, or are only given explicit attention in courses in Euclidean geometry. Geometry is also…

The First Year Inventory (FYI) is a parent report screening measure, aimed at identifying the risk of autism spectrum disorder (ASD) in 12-month-old infants. This study aimed to investigate the utility of FYI within the Chinese community and develop a short version, encompassing both a low-risk sample and a high-risk sample comprising infants with…

Although it is commonly believed that automation aids human decision-making, conflicting evidence raises questions about whether individuals would gain greater advantages from automation in difficult tasks. Our study examines the combined influence of task difficulty and automation reliability on aided decision-making. We assessed decision…

The scope of the school nursing practice tool (SSNPT) is needed to apply and explore the gap between what school nurses perceive as important and actual practices. This study adapted and validated the Korean version of SSNPT (K-SSNPT) among 360 Korean school nurses in January 2022. The reliable and valid K-SSNPT can inform school nurses' workforce…

Career aspirations of high school students is a significant motivational force for learning engagement. However, validated methods for probing their career aspirations remain unestablished. Study 1 used 1455 high school students to develop a career aspirations questionnaire (CAQ). The CAQ was developed through item generation, pretesting,…

We study the external validity of instrumental variable estimation. The key assumption we impose for external validity is conditional external unconfoundedness among compliers, which means that the treatment effect and target selection are independent among compliers conditional on covariates. We study this assumption with a case study about the…

Background/purpose: The application of learning models is expected to significantly promote the enhancement of students' problem-solving abilities through the development of interactive learning models. This study aims to (1) determine whether the Development of the Component Display Theory (CDT) Model is categorized as valid, practical, and…

Although ethical sensitivity is a well-defined concept, few scales specifically assess the ethical sensitivity of students in higher education referring to academic honor codes. We conducted the current study to develop and validate a scale that measures the Ethical Sensitivity Scale in Academic Activities (ESS). Scale development followed a…

A successful teaching-learning process depends heavily on teaching. Wherein the teaching process greatly benefits from the involvement of prospective teachers. They need to approach the teaching with a positive attitude for the teaching-learning process to be effective. Therefore, a reliable instrument is required for assessing the prospective…

Autism Spectrum Disorder (ASD) must be present early in development, but may not fully manifest until social demands exceed capacities. In the absence of adequate biological or brain imaging markers to detect and diagnose autism, diagnosis relies on clinical judgment based on observation of symptoms. Many tools have been developed in…
