This study aims to introduce a method that is based on the relationship between numbers and geometry, which can be used to show the exact location of rational numbers on the number line, compare rational numbers, make calculations, and examine rational numbers conceptually through parallel lines. It is believed that this method will to contribute…

The Cattell-Horn-Carroll (CHC) taxonomy of cognitive abilities married John Horn and Raymond Cattell's Extended Gf-Gc theory with John Carroll's Three-Stratum Theory. While there are some similarities in arrangements or classifications of tasks (observed variables) within similar broad or narrow dimensions, other salient theoretical features and…

This investigation examined the influence of gender and education attainment on engagement in antisocial and risk-taking behaviours and emotional dysregulation. A convenience sample (N = 285) of Australians, aged between 18 to 74, completed the Antisocial Engagement Questionnaire and the Difficulties in Emotion Regulation Scale. Gender differences…

Prompted by the evidence of international tests of achievement that Swedish students have poor equation solving skills, this paper presents an interview study of upper secondary students' understanding of the topic. Students, from both vocational and academic tracks in two typical suburban upper secondary schools were invited to explain how a…

In this paper, we derive an equation for the distance covered by a free-falling body as a function of time valid for any arbitrary distance. The equation, interestingly, yields exactly the time according to the Kepler's third law in the limiting case of very large distance compared to the radius of the Earth. The equation, of course, reduces to…

The present study examined the psychometric properties of a brief parent-report daily checklist of toddler behavior (Parent Daily Report--Toddler Version; PDR-T). Data were collected from three groups of 18-36 month-olds who were followed longitudinally for approximately one year: (a) internationally adopted children (N = 156); (b) children placed…

The integration of Science, Technology, Engineering, and Mathematics Project-Based Learning (STEM PBL) into educational curriculum has received much attention because of its strength in improving students' affective engagement. We designed the present study to investigate the effectiveness of STEM PBL lessons on 9th grade students' development of…

The sociological imagination is a core component of all introductory sociology courses. A main focus of this perspective is how social forces are related to individual lives. Undergraduates are often socialized to rely on individualistic explanations of public issues. These explanations often blame, dehumanize, and other the victim, thereby…

The aim of this study is to determine the extent to which prospective teachers' metacognitive skills, problem solving skills and academic self-efficacy explain their critical thinking tendencies. This study, designed as correlational survey method, was conducted with 229 prospective teachers studying at Van Yüzüncü Yil University, Faculty of…

Recently, Gauthier introduced a method to construct solutions to the equations of motion associated with oscillating systems into the mathematics education research literature. In particular, Gauthier's approach involved certain manipulations of the differential equations; and drew on the theory of complex variables.Motivated by the work of…

Should the topic of judgment have a place in the preparation and development of school leaders? This question serves as the focus for an examination of the nature of judgment and obstacles to good judgment. Judgment is defined as the ability to arrive at and make a choice when faced with incomplete information, uncertain conditions, and/or…

The need for methods, techniques and approaches that we can develop high-level thinking skills in important activities increases day by day in order to achieve effective use of technology and change in information and communication technologies. In particular, the diversity, complexity of technical skills and to gain technical skills required to…

Cognitive model [CM] is the description of individual's problem-solving method on selected tasks at a precise level to make meaningful inference on his/her strengths and weaknesses. CM serves as a foundation in developing a cognitive diagnostic assessment [CDA] that links the interpretation of test score to the attributes. This study employed the…

The mathematics education field recognizes the importance of noticing children's mathematical thinking as a means for supporting children in learning mathematics (Sherin et al. Mathematics teacher noticing. Routledge, New York, 2010). Using the existing literature base around teachers' knowledge of children's mathematical thinking and…

Evidence demonstrating the effectiveness of the School-wide Positive Behaviour Intervention Support model (SWPBIS) in managing problem behaviour among school students has been widely disseminated. As a result, the SWPBIS model is now widely implemented in schools across the US. Despite its widespread implementation and evidence demonstrating its…
