Tangent lines are often first introduced to students in geometry during the study of circles. The topic may be repeatedly reintroduced to students in different contexts throughout their schooling, and often each reintroduction is accompanied by a new, nonequivalent definition of tangent lines. In calculus, tangent lines are again reintroduced to…

The Flourishing Scale is a new scale designed to measure psychological well-being. FS has been translated into more than 10 languages (e.g., Portuguese, Russian, Turki, Spanish, Egyptian, French, Chinses, Japanese, Malay, Urdu, and Persian). The psychometric analysis of the Flourishing Scale has not been explored in the Malaysian context. The aims…

This study investigated the effectiveness of inquiry-based learning (IBL) approach in ratio and proportion on the mathematics reasoning skill of seventh-grade students. The study was carried out in a seventh-grade mathematics course in a middle school located in the Central Anatolia region of Turkey during the 2016-2017 academic year. The IBL…

Generalization and proof are a foundation of mathematical practice and as such should be integral to K-12 mathematics instruction. However, if generalizing and proving are to become popular within K-12 mathematics classrooms, we must consider how to effectively enlist pre-service teachers (PSTs) into supporting these activities in their…

Different approaches have been used to teach EFL students summary writing, including a genre-based approach (Chen & Su, 2012), implementing key words and question generation (Chou, 2012), and automatic scaffolding and concept mapping (Yang, 2015). This study aims to explore the effectiveness of another approach--one that might be more…

Teaching in Vietnam recently, I had opportunities to work with some amazing students and teachers. Being in such a position lent itself well to cultural exchanges inside and outside the classroom. However, it was clear to me, to my colleagues, and I believe to the majority of students that there was a need to dig deeper--to move beyond the…

The present study reports on the first investigation of the generalizability of the psychometric properties of the Student Subjective Wellbeing Questionnaire (SSWQ) beyond the original development and replication studies. Previous studies tested an English version of the SSWQ with urban, mostly Black/African American, low socioeconomic status,…

This paper reports on the results of a study investigating the potential to embed Informal Statistical Inference in statistical investigations, using TinkerPlots, for assisting 8th grade students' informal inferential reasoning to emerge, particularly their articulations of uncertainty. Data collection included students' written work on a…

This document reports the results of a 4-month experimental study designed to determine the effectiveness of using computers with interactive software programs to teach higher-order thinking skills. The effects of CAI (computer-assisted instruction) on affective domains were assessed, as well as the effectiveness of CAI with interactive software…

Students' evaluations of teacher effectiveness are explored as a multidimensional construct, emphasizing the Students' Evaluations of Educational Quality (SEEQ) instrument developed by H. W. Marsh (1987). An overview is presented of studies in which Marsh evaluated longitudinal data from an archive of responses to nearly 1 million SEEQ instruments…
