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 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…

The aim of this study is to develop a valid and reliable achievement test on the subject of 'Basic Compounds in the Structure of Living Things'. During the preparation of the draft form of the test, a 32 item-question pool was created by the researchers in the light of the relevant literature. Then, these questions were presented to expert opinion…

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…

Researchers in science education lacks valid and reliable instruments to assess students' "disciplinary" and "epistemic" reading of scientific texts. The main purpose of this study was to develop and validate a Reading in Science Holistic Assessment (RISHA) to assess students' holistic reading of scientific texts. RISHA…

Online metacognitive skills are the real-time awareness of cognition, which can effectively promote science learning and improve performance in solving scientific problems. Therefore, it is important to enhance and diagnose students' online metacognitive skills in science education. This study aimed to evaluate ninth-grade students' online…

This study aimed to develop a STEM module for eighth-grade middle school learners through the engineering design process. The module was developed based on the ADDIE model, primarily concentrating on the stages of analysis, design and development. The study consisted of two main phases: module development and module evaluation. During the…

In this study, we use estimated public transit routes for high school students in Baltimore City to predict the number of days they are late during the school year. We find that after adjusting for individual and school characteristics, school preferences, and neighborhood fixed effects, total travel time and transit use are not predictive of…

The Student Subjective Wellbeing Questionnaire (SSWQ) is a 16-item measure of school-specific subjective wellbeing intended for mental health screening applications. We extended past validation work to scrutinize the SSWQ's previously proposed factor structure (i.e., four group factors; one general factor) and score reliability using two random…

A prior study developed the Computational Thinking Scale (CTS) for assessing individuals' computational thinking dispositions in five dimensions: decomposition, abstraction, algorithmic thinking, evaluation, and generalization. This study proposed the Developmental Model of Computational Thinking through validating the structural relationships…

School climate measures are important tools that assist educators in evaluating the "norms, values, and expectations that support people feeling socially, emotionally and physically safe" (National School Climate Council, 2007, p. 4). Positive school climate is associated with academic performance indicators such as grade point average,…

One of the major purposes of this study is to investigate the potential impact of gender and information and computer technology (ICT) resources on students' computational thinking (CT) competencies. To this end, the Computational Thinking Test for Junior High Students (CTT-JH) was developed and validated. Research participants included 437 junior…

In this study, it was aimed to examine 9th grade students' multiple representation translate skills in algebra learning area and the relationship between these representations translate skills. The study employs survey design. Selected through purposive sampling method, 637 ninth grade students in a socio-economically medium level province in…

Adolescent thinking about the wrongness of antisocial behaviours plays a key role in their own engagement in antisocial conducts. Nevertheless, measures assessing adolescent antisocial evaluations are not common in literature. Informed by the social domain theory and using adolescent actual thinking about antisocial behaviours, this study…

The inconsistency task is used to measure metacognitive monitoring in text comprehension via online (reading time) and offline measures (number of detected inconsistencies). Few studies have examined stability in task performance and interindividual differences. We addressed these issues with adolescents (N = 341) in Grades 6/7 (Mage =…
