Climate change worry (CCW) is a specific worry about climate change, involving thoughts about changes that might occur in the climate system and their possible effects. Nowadays, it is growing especially among adolescents. As there is a lack of measurement tools with adequate psychometric properties to assess CCW in this age group, we investigated…

Gas Turbine Engines (GTE) have the highest power-to-weight ratio among Internal Combustion Engines (ICE). Its modularity and ability to utilize various types of fuel make it highly recommended in power plants, naval transportation, and, of course, the most equipped in aviation. The lack of GTEs' real data is increasing a recognized need for…

Scores on the Test of English for International Communication Listening and Reading (TOEIC LR) have been used for rolling-based university admissions in South Korea. Because this test is not designed for that purpose by the testing organization, there may be a need to explore the validity of TOEIC LR score use for admission purposes. Accordingly,…

The long-term goal of the State Systemic Improvement Plan (SSIP) and other federal and state early intervention and early childhood education initiatives is improved child and family outcomes. States play a critical role in supporting practitioners in the use of evidence-based practices to improve child and family outcomes. When practitioners…

Student surveys have gained prominence in recent years as a way to give students a voice in their learning process, and teacher self-reports have always been an effective instrument for revealing the planning, intentions, and expectations behind a given lesson. Though student and teacher surveys are widely used, extant research in education has…

This study examined the validity of a Chinese version of the Social Achievement Goal Orientation Scale (C-SAGOS), a measure testing the trichotomous framework of achievement goal orientations in a social domain. A total of 208 college students (51% female) aged 18 to 23 participated in the study. Factor analyses showed that the three-factor model…

Accountability mandates often prompt assessment of student learning gains (e.g., value-added estimates) via achievement tests. The validity of these estimates have been questioned when performance on tests is low stakes for students. To assess the effects of motivation on value-added estimates, we assigned students to one of three test consequence…

Understanding attitudes toward science and measuring them remain two major challenges for science teaching. This article reviews the concept of attitudes toward science and their measurement. It subsequently analyzes the psychometric properties of the "Test of Science-Related Attitudes" (TOSRA), such as its construct validity, its…

Measurement invariance (MI) is a property of measurement that is often implicitly assumed, but in many cases, not tested. When the assumption of MI is tested, it generally involves determining if the measurement holds longitudinally or cross-culturally. A growing literature shows that other groupings can, and should, be considered as well.…
