In this paper, we analyse a grade 8 (age 13-14) Japanese problem-solving lesson involving angles associated with parallel lines, taught by a highly regarded, expert Japanese mathematics teacher. The focus of our observation was on how the teacher used carefully planned board work to support a rich and extensive plenary discussion (neriage) in…

Automatic machine learning (AutoML) methods automate the time-consuming, feature-engineering process so that researchers produce accurate student models more quickly and easily. In this paper, we compare two AutoML feature engineering methods in the context of the National Assessment of Educational Progress (NAEP) data mining competition. The…

Validity is one of the psychometric properties of the achievement tests. To determine the validity, one of the examination is item bias studies, which are based on differential item functioning (DIF) analyses and field experts' opinion. In this study, field experts were asked to estimate the DIF levels of the items to compare the estimations…

Just for a change, would it not be nice to hear talk about keeping and/or expanding full-time art specialists' presence in schools and maintaining strong art education programs at the college and university level?

This Teaching and Learning Research Initiative (TLRI) project was a 2-year exploratory study focusing on differentiating the curriculum in response to individual learner differences. The project was designed to explore learning and teaching of differentiated scientific content through observational processes and the expression of that learning…

This research examined the relevance of professional associations to effective reading teaching in Chicago Public Schools (CPS). It looked at the performances of students in meets and exceeds in the Illinois State Achievement Test (ISAT) for third and eight grade students in selected schools in CPS between 1999 and 2004 and how the professional…

This article examines how conversations during design reviews in which 8th-grade mathematics students shared population models with visiting specialists expanded the disciplinary expertise of the classroom. "Re-contextualizing" is a conversational exchange that visiting specialists initiated to invite groups to consider their models in novel…

Today's world is challenged by complex issues and citizens need ever-increasing scientific literacy to understand the impact of issues such as global warming, alternative energy, and genetic engineering, on their daily lives and to make informed decisions. Students need to be prepared to tackle issues such as these by being exposed to learning…

This study used qualitative methodology to investigate the self-efficacy beliefs of early adolescents with learning disabilities (LD). We conducted a series of focus group interviews with 28 Grade 8 and 9 students with LD and individual interviews with 7 specialist LD teachers.
