This document introduces, describes and exemplifies the technical features of some recently implemented automated reasoning tools in the dynamic mathematics software GeoGebra. The new tools are based on symbolic computation algorithms, allowing the automatic and rigorous proving and discovery of theorems on constructed geometric figures. Some…

Background: There is a need for engineering-specific theories and constructs to advance our understanding of student development. Student integration, widely used in educational research, is a suitable construct; however, it has also received some criticism. These critiques can be addressed by rethinking student integration and its use in the…

This article presents pilot study results of two leadership performance assessments, designed for a California principal preparation program and embedded in preparation using two learning approaches. The pilot study had two purposes: to evaluate the assessments' content validity and to evaluate the candidates' leadership skills as demonstrated…

The phenomenon of "digital divide" is complex and multidimensional, extending beyond issues of physical access. The purpose of this study was to develop a scale to measure a range of factors related to digital divide among higher education faculty and to evaluate its reliability and validity. Faculty's Information and Communication…

When educators teach entrepreneurship experientially in higher education, a need arises for different procedures for assessment, evaluation and feedback, and the legitimacy of this type of course is often questioned. In traditional courses, students accumulate knowledge and the educator's primary concern is "what" students learn. When…

Visual input enhancement (VIE) increases the salience of grammatical forms, potentially facilitating acquisition through attention mechanisms. Native English speakers were exposed to an artificial language containing four linguistic cues (verb agreement, case marking, animacy, word order), with morphological cues either unmarked, marked in the…

The psychometric properties of a new multidimensional measure of test anxiety, the Test Anxiety Measure for College Students (TAM-C), based on theory and current research were examined in a sample of 312 Canadian college students online. The TAM-C consists of a Facilitating Anxiety scale and five test anxiety (Cognitive Interference, Physiological…

Approximately, 283 sixth-grade students completed four randomly generated Math Curriculum-Based Measures (M-CBMs) from interventioncentral.org twice during a fall semester. These M-CBMs measured foundational skills in addition, subtraction, multiplication, and division. We found that using mean fluency or accuracy scores from four M-CBMs produced…

This study aims to validate a recent new media literacy (NML) instrument and investigating NML levels of Turkish preservice teachers. A refined NML framework formed the theoretical basis of the study. The data were collected from 972 preservice teachers enrolled in 11 teacher training programs in 5 public universities in Turkey. The language…

Currently, there is a need to assess the impact of ICT educational policies in educational centres. In this study, the level of digital competence of students is proposed as an indicator of the impact of these policies. However, there is an international problem when it comes to measuring this competence due to its diversity and conceptual…

Background: The current body of research on job satisfaction of people with intellectual disability is based on highly diverse measures, originating both from the general population and people with intellectual disability. This heterogeneity represents a possible confounder. Best-practice approaches for the assessment of job satisfaction are hence…

This study aims to the comparison of body image satisfaction levels of athletes in individual and team sports. The sample of the study was selected by 34 athletes engaged in athletics, 52 athletes engaged in boxing, 45 athletes engaged in wrestling, 37 athletes engaged in weightlifting, 36 athletes engaged in handball, 35 athletes engaged in…

There is currently a hot debate in the literature regarding whether or not infants have a true theory of mind (ToM) understanding. According to the mentalistic view, infants possess the same false belief understanding that older children have but their competence is masked by task demands. On the other hand, others have proposed that preverbal…

With the intent of amending the 21-item BDI-II to improve its reliability and validity when administering the scale to nonclinical populations, a survey package consisting of 19 positive items with semantically reflected response options to mirror the negative scenario options in the original BDI-II (excluding items 16 and 18) was created. These…

To facilitate rigorous research on community programs to promote positive intergroup relations among youth, 2 studies were conducted to establish the psychometric properties of the Youth Diversity Acceptance Scale (YoDA). In Study 1, a unifactorial structure was identified for the YoDA using data provided by 126 high school youth involved in a…
