A Validity Study Applying the Rasch Model to the American Association for the Advancement of Science Force and Motion Sub-Topic Assessment for Middle School Students.

The purpose of this research was to investigate the reliability of the scores produced and validity of the inferences drawn from the American Association for the Advancement of Science (AAAS, 2018) force and motion sub-topic assessment for middle school students. The assessment of student outcomes in STEM is an international focus in K-12 education. Project 2061, initiated by the AAAS, focuses on addressing challenges related to standards and assessments.

Developmental trajectories of math anxiety during adolescence: Associations with STEM career choice.

The purpose of this study was to determine if there were distinct developmental trajectories of math anxiety during adolescence and if these trajectories predicted later STEM career choice. The study also evaluated whether the trajectories varied in relation to gender and race/ethnicity. Data were drawn from Longitudinal Study of American Youth-younger cohort that consisted of 3116 nationally representative sample of 7th grade students (48% Female, 70% European American) that were followed for 7 years.

Rasch Derived Teachers' Emotions Questionnaire.

The purpose of this research was to estimate the reliability of the scores produced from and validity of the inferences drawn from the revised 90-item Teachers' Emotion Questionnaire consisting of three measures: frequency of emotional expressivity, self-efficacy for regulation of emotional expressivity when teaching, and self-efficacy for regulation of context-specific emotional expressivity. A void exists in an instrument assessing teachers' regulation and communication of their emotions. One-hundred seventeen practicing teachers participated in this study at Time 1 and 46 at Time 2.

Students' daily emotions in the classroom: intra-individual variability and appraisal correlates.

Background: Recent literature on emotions in education has shown that competence- and value-related beliefs are important sources of students' emotions; nevertheless, the role of these antecedents in students' daily functioning in the classroom is not yet well-known. More importantly, to date we know little about intra-individual variability in students' daily emotions.

Aims: The objectives of the study were (1) to examine within-student variability in emotional experiences and (2) to investigate how competence and value appraisals are associated with emotions.

Perceived social support and early adolescents' achievement: the mediational roles of motivational beliefs and emotions.

Although a bulk of literature shows that perceived social support (PSS) influences academic achievement, the mechanisms through which this effect operates received little empirical attention. The present study examined the multiple mediational effects of motivational beliefs (competence beliefs and subjective value) and emotions (anxiety and enjoyment) that may account for the empirical link between PSS (from parents, peers and teachers) and mathematics achievement. The participants of the study were 238 grade 7 students (average age = 13.
