This paper demonstrates how to apply Machine Learning (ML) techniques to analyze student interaction data collected in an online mathematics game. We examined: (1) how different ML algorithms influenced the precision of middle-school students' (N = 359) performance prediction; and (2) what types of in-game features were associated with student…

A caring school community can enhance whole-school wellbeing including the wellbeing of school staff, which directly impacts on student academic, social and emotional wellbeing. This study firstly examines the validity and reliability of a proposed wholeschool staff wellbeing evaluation tool which uses a set of whole-school wellbeing indicators to…

This study puts forward a comprehensive digital citizenship scale based on carefully calibrated, overarching, inclusive components of digital citizenship that can be used to measure abilities, perceptions, and levels of participation of young adults in Internet based community. A 26-item five-factor model was extracted using an Exploratory Factor…

The Social-Emotional and Character Development Scale (SECDS) is intended as a measure of social-emotional skills and character for elementary school-age children. This study investigated the measure's psychometric properties using data collected over 5 waves for a cohort of students followed from Grades 3 to 5 in 14 urban elementary schools (N…

This paper discusses the development of a Cultural Anxiety Scale (CAS) for Chinese students studying in the United States. One hundred items were developed using the anxiety research literature, a survey of research on stress and anxiety among college students, and Chinese cross-cultural studies. Face, construct, and content validity analysis were…

This study examined the psychometric properties of the Input Anxiety Scale, the Processing Anxiety Scale, and the Output Anxiety Scale, (all developed by P. MacIntyre and R. Gardner, 1994) which measure anxiety at the input, processing, and output stages of the foreign language learning process. These scales were administered to 258 university…

Because the literature suggests that aerobic exercise is associated with physical health and psychological well-being, there is a concern with discovering how to improve adherence to such exercise. There is growing evidence that self-motivation, as measured by the Dishman Self-Motivation Inventory (SMI), is a redictor of adherence to regular…

Alcohol abuse is a widespread problem on university campuses. A theoretical explanation of alcohol abuse is the Tension Reduction Theory (TRT), which predicts that alcohol reduces tension and that alcohol is consumed because of its tension-reducing effects. This study examined the validity of this theory. College students (N=81) completed the…

The purpose of this study was to develop and gather initial validity evidence for a scale designed to assess teacher knowledge and practice regarding statistics anxiety and negative attitudes toward statistics. A secondary purpose was to assess the levels of encouragement, knowledge of statistics anxiety, and current teaching practices of…

The psychometric adequacy of the Social Interaction Scale and the Social Phobia Scale (both by R. P. Mattick and J. C. Clark, 1989) was studied with 165 patients with anxiety disorders and 21 people without anxiety. Results support the usefulness of the scales for screening and treatment design and evaluation. (SLD)

Social facilitation can be defined as the effect of an audience or coactors on performance. Research on social facilitation effects has produced some contradictory and confusing findings. Some studies have found that the presence of others enhances performance; other studies have found that the presence of an audience or coactors impairs…

The factor structure, and thereby the underlying construct of the What I Think and Feel Test (WITF) was determined. The delineation of subscales of anxiety within this revision of the Children's Manifest Anxiety Scale was significant, since anxiety is a multidimensional characteristic. Responses of 329 children (grades 1-12) to the 28 anxiety…

The Alpert-Haber Achievement Anxiety Test was developed to measure the extent to which individuals experience test anxiety. In at least two published studies, the authors claim to have used the test when in fact the response format was changed from that used in the original instrument and the "buffer" items were omitted. To investigate…

A self-report, paper-and-pencil version of the Hamilton Depression Rating Scale, the Hamilton Depression Inventory, was developed and tested with 140 depressed adults, 99 adults with anxiety disorders, and 118 nonreferred adults. Overall, data support the reliability and validity of the new measure. (SLD)

The "Minimood" is the synonym chosen from the adult mood adjective checklist (MACL) to measure moods of elementary children. Ratings were obtained on mood and Children's Manifest Anxiety Scales (CMAS) for a 50-subject pilot and a 206-subject developmental sample in grades 1, 3, and 5. Twelve mood factors were identified: Aggression,…
