A tree model for diagnostic educational testing is described along with Monte Carlo simulations designed to evaluate measurement accuracy based on the model. The model is implemented in an assessment of inferential reading comprehension, the Multiple-Choice Online Causal Comprehension Assessment (MOCCA), through a sequential, multidimensional,…

There is ongoing debate regarding what performance on the number line estimation task represents and its role in mathematics learning. The patterns followed by children's estimates on the number line task could provide insight into this. This study investigates children's estimation patterns on the number line task and assesses whether mathematics…

This quantitative study aims to determine if there is a relationship between schools that had one-to-one technology programs pre-pandemic, and achievement test score outcomes. The study focused on the twenty-three school districts that had one-to-one programs pre-pandemic in Mississippi, and compared their performance with test scores from…

Differentiation is an instructional practice teachers employ to modify their classroom content, process, and products based on student readiness, interest, and learning profile. Many school districts recognize the benefits of differentiated instruction and thus mandate allotted classroom time for its implementation. In this paper, we investigate…

In response to increasingly diverse student groups in U.S. schools, educational researchers have developed curricula that respond to students' unique needs, cultures, and experiences. Curricula that embrace a pedagogy of empowerment are known as Culturally Responsive Curricula (CRC), and such curricula specific to science are referred to as…

Often included within 'high-risk sibling' studies, the Autism Observation Scale for Infants (AOSI) has only one independent replication study and no evaluation with community-ascertained cohorts. We administered the AOSI and established clinical measures with 103 infants (68% male) at 'high autism likelihood' on the Social Attention and…

This study belongs to assessment-related research and aimed to investigate Finnish high-school students' (n = 211) topic-specific epistemic beliefs about climate change and whether the Norwegian topic-specific epistemic beliefs questionnaire (TSEBQ) was also valid among Finnish respondents. Thus, research data were not only derived from the TSEBQ…

The Colorado Learning Attitudes about Science Survey (CLASS) is an instrument to measure student beliefs about physics and learning physics. In this research, Turkish adaptation and psychometric evaluation of the CLASS is discussed. In the first stage, the translation process, which included examination of six experts (four experts in physics…

Background: Research on character strengths in individuals with multiple sclerosis (MS) is lacking. Moreover, measures of character strengths have not been validated in this population, limiting the opportunities for further investigation. Objective: To investigate the factor structure of the Values in Action Inventory of Strengths (VIA)-72 in a…

Individuals encounter problems daily wherein varying numbers of constraints require delimitation of memory to target goal-satisfying information. Multiply-constrained problems, such as the compound remote associates, are commonly used to study this type of problem solving. Since their development, multiply-constrained problems have been…

With the purpose of developing an instrument for measuring statistics anxiety in the online or hybrid setting, this study tested the newly developed instrument in two stages. Results on item selection and exploratory factor analysis based on pilot testing (n = 115) are presented. Results on classical item analysis, the confirmatory factor…

The Academic Encouragement Scale (AES) evaluates academic encouragement received from someone whom the student respects. This study reported the psychometric properties of the AES among 1602 Chinese adolescents. The results of confirmatory factor analysis (CFA) supported a two-factor structure of the AES (i.e., challenge-focused encouragement…

Though there is substantial evidence that individuals can prioritize more valuable information in visual working memory (WM), little research has examined this in the verbal domain. Four experiments were conducted to investigate this and the conditions under which effects emerge. In each experiment, participants listened to digit sequences and…

The purpose of this study was to develop and validate a novel scale, the Development and Validation of Out-of-School Learning Environments Perception Scale (OSLEPS), that measures middle school students' perceptions of out-of-school learning environments. A total of 990 middle school students (583 females and 407 males) participated in the study.…

This study proposes explanatory cognitive diagnostic model (CDM) jointly incorporating responses and response times (RTs) with the inclusion of item covariates related to both item responses and RTs. The joint modeling of item responses and RTs intends to provide more information for cognitive diagnosis while item covariates can be used to predict…
