Sourcing information related to socio-scientific issues requires sophisticated literacies to read and evaluate conflicting accounts often signified by disagreement among experts, multiple solutions or misinformation. Much of the previous work exploring how young people approach conflicting information has tended to focus on students in the…

Questionnaire scales that are mixed-worded, i.e. include both positively and negatively worded items, often suffer from issues like low reliability and more complex latent structures than intended. Part of the problem might be that some responders fail to respond consistently to the mixed-worded items. We investigated the prevalence and impact of…

Stability and change in students' achievement goals (AGs) are of great relevance for educational research and practice. In two separate meta-analyses, we investigated the rank-order stability (93 studies, 569 effect sizes, 54,736 students), as well as the mean-level change (157 studies, 1,170 effect sizes, 81,464 students) in AGs throughout…

The Social Emotional Health Survey-Secondary-2020 (SEHS-S-2020) is a well-studied option for assessing social emotional health to support students within a multitiered system of school support. While a growing body of literature supports the SEHS-S-2020 measure for assessing student covitality, there is less validation evidence specifically for…

The main objective of this study is to revise and validate the assessment of self-presentation skills of middle school students. The assessment is based on existing self-assessment scales and adaptively modified for a more accurate assessment of middle school students' self-presentation skills. Considering the characteristics of middle school…

This study aims to evaluate students' ability to process the context information embedded in chemistry problems. To achieve this goal, a diagnostic measurement instrument was developed, comprising 28 short-answer items embedded in seven context-based chemistry tasks. Four hundred and ninety-three ninth-graders took part in the testing in Jiangsu,…

This is the sixth and culminating study in a series whose purpose has been to acquire a conceptual understanding of school band performance and to develop an assessment based on this understanding. With the present study, we cross-validated and applied a rating scale for school band performance. In the cross-validation phase, college students…

This study developed an Adolescents' Uncertainty Scale (AUS), with the aim of understanding individual differences in uncertainty among adolescents. In the pretest phase, 507 ninth-grade students were recruited. After exploratory factor analyses, a 25-item AUS with four dimensions--irresoluteness, instability, lack of self-knowledge, and…

This study contributes to the call for influencing practice by increasing attention to how learning environments can be designed to support learning in statistical inference. We report on a design experiment in secondary school (students 14-16 years old), that resulted in a set of lessons with the learning goal of teaching students how to apply…

Purpose: There is little consensus in the literature regarding a) what it means for a school leader to lead with data, and b) how to measure data-informed leadership in a reliable and valid way. This study examines the psychometric properties of an operational measure intended to assess the extent to which a school leader is a data-informed school…

Rubrics are popular tools to assess students' social-emotional skills. However, little research has been devoted to investigating whether rubrics' performance level descriptions validly represent the intended skills. In this study, we addressed the validity of Self-management rubrics by examining the presence of construct-irrelevant variance in…

Early adolescence is a time marked by upheaval and change. Youth are navigating increased social pressures from constant connection with peers. Youth have access to 24 hours of social connection via technology, but they increasingly report feelings of isolation, anxiety, and depression (Keles et al., 2020). They are also entering a world with…

This study explores how seven middle and secondary teachers understood and developed ambitious pedagogies within the context of their own classroom. Although there has been an emphasis on preparing preservice teachers for utilizing ambitious pedagogies, these practices are often not observed in practicing teachers' classrooms. The purpose of this…

This study aims to develop a knowledge test to assess secondary school students' awareness of scientists. After determining the topics that the questions in the test would measure, 50 multiple-choice questions were prepared and presented to six experts in the field. Following the experts' feedback, the number of questions in the test was reduced…

With the development of the Internet as a main source of information, teenagers are increasingly faced with multiple documents which may contain contradictory statements, and whose reliability must be assessed. One way to assess information reliability is to evaluate the source of the information (e.g., author expertise, intention). However,…
