Racially and ethnically diverse populations from minoritized backgrounds are often exposed to research methodologies that amplify structural racism and negate their sociocultural reality. Although cross-cultural validation of measures is considered a requisite step to multigroup comparisons, researchers apply measures validated and standardized in…

The aim of this study is to develop a theoretically sound, valid, and reliable scale to examine seventh and eighth grade students' attitudes towards so-called skill-based mathematics questions (SBMQ). The sample of the study was 820 seventh and eighth grade students at three different middle schools in Etimesgut District of Ankara Province. A…

We present a case study of proving by three 12-13-year-old students with different levels of mathematical giftedness. After analysing students' proofs, we conclude that: there was a relation on the consistency and the students' levels of mathematically giftedness, being the least consistent the student not mathematically gifted and the most…

The aim of this study is to construct a STEM competencies assessment framework and provide validity evidence by empirically testing its structure. Common interdisciplinary assessment frameworks for STEM seem to be scarce in the literature. Many studies use students' mathematics or science scores obtained from large-scale assessments or exams to…

In this paper, Harel and Sowder's proof schemes of taxonomy were applied for identifying eighth grade students' learning of proof and proofing. This study aimed to examine what kind of proof schemes are used in geometry and measurement learning areas and student's skills in giving proof and their opinions about proof. Qualitative methods were…

The purpose of the present study is to provide empirical evidence on the adaptation of the mathematics-related beliefs questionnaire (MRBQ) supplemented by info-communication technology-related items. Besides, we also investigate the relationship between their beliefs about mathematics and their ability in problem-solving mathematics. 234 grade…

Students' science identity has been identified as an important construct that positively influences their learning engagement, persistence, and career intentions in science. This paper reported the process of developing and validating an instrument that can be used to assess high school students' science identity. The development of this…

This study was conducted to develop a valid and reliable measurement tool that can identify middle school students' self-regulation skills. Firstly, the literature was utilized in the development of the measurement tool. The form was finalized with the support of the opinions of different experts and a trial application. Then, the form was…

The study aimed to develop and evaluate the psychometrical properties of a new brief measure of gender stereotyping career attitudes. Participants were 222 early and 196 middle adolescents from Croatia. The Vocational Gender Stereotype Attitudes Scale (VGSA) consists of 12 items that represent masculine, feminine and gender-balanced activities…

In this action study, instructional environments were enriched with activities related to the history of mathematics in order to deepen students' beliefs about mathematics and reveal for them fun, interesting, and useful activities. The study enrolled twenty-four 8th-grade students. Data were collected by using multiple data collection tools. The…

The Modeling Self-Efficacy Scale was developed to measure students' confidence in understanding and solving modeling tasks. The scale was administered to 225 eighth- and ninth-grade students. Participants read modeling tasks adapted from Programme for International Student Assessment's 2003 problem-solving assessment and rated their confidence on…

The aim of the present study was to develop the Science Amotivation Scale (SAS) in order to determine amotivation levels among demotivated students in science classes as well as examine the reasons causing amotivation. The participants were 533 students (6th, 7th, and 8th grade) studying across secondary schools located in Kars city centre in…

Background: Several different measures have been proposed to solve persistent validity problems, such as high task-sampling variability, in the assessment of students' expertise in 'doing science'. Such measures include working with a-priori progression models, using standardised item shells and rating manuals, augmenting the number of tasks per…

The National Assessment of Educational Progress's (NAEP's) transition to an entirely digitally based assessment (DBA) began in 2017. As part of this transition, new types of NAEP items have begun to be developed that leverage the DBA environment to measure a wider range of knowledge and skills. These new item types include the science…

In the current study, the researchers examine the validity of a questionnaire assessing students' perceptions of their self-directed and collaborative learning with and without technology with a group of Canadian middle school students. Lee and colleagues (2014) developed the 18-item questionnaire to assess high school students' perceptions of…
