The present study investigates the effect of the separator lines on the learning of 8th grade students in simplifying algebraic expressions with parenthesis. An experimental study was designed to achieve this goal involving 60 girl students in 8th Grade (13 and 14 years old) randomly selected and assigned to two experimental and control groups.…

Productive struggle is a process in which students expend effort to grapple with perplexing problems and make sense of something that is not immediately apparent and beyond their current level of understanding and capacity. The experience encourages students to reflect on and restructure their existing knowledge toward a new understanding of…

The aim of this study is to examine how middle school mathematics teachers diagnose and attempt to eliminate students' misconceptions in algebra. The study employed a case study method and embedded single-case design. The research was conducted with three mathematics teachers working in different state schools and having different professional…

The aim of this study is to reveal and evaluate the attending and interpreting skills of student thinking of prospective teachers, as well as their instructional suggestions as responding skills. The current study was conducted with 29 prospective mathematics teachers (PMTs) within a qualitative design in the context of probability. First, three…

Troubleshooting activities require students to diagnose teacher-crafted erroneous examples by detecting and explaining the conceptual errors driving them. In a previous study, the author tested whether diagnosing erroneous examples and then scoring them using a rubric that contained the related worked examples, a step-by-step strategy to solve a…

This study investigates how different form-focused instruction (FFI) timing impacts English as a foreign language (EFL) learners' grammar development. A total of 169 Chinese middle school learners were assigned to four conditions randomly: control, before-isolated FFI, integrated FFI, and after-isolated FFI. The three experimental groups received…

The effect of writing strategy instruction on three middle school students' narrative writing performance in actual classrooms was investigated. The results indicated that the writing strategy instruction improved writing performance of students with and without disabilities, as well as students who were English language learners when provided…

This study compared students' learning in troubleshooting and problem solving activities. The troubleshooting activities provided students with solutions to conceptual problems in the form of refutation texts; namely, solutions that portray common misconceptions, refute them, and then present the accepted scientific ideas. They required students…

Students with emotional and behavioral disorders (EBD) typically exhibit significant behavioral excesses or deficits that interfere with their learning and sometimes that of their peers in the classroom. These behaviors can generally be described as either external and easily noticed (e.g., disruption, aggression) or internal and easily overlooked…

This study examines the mediating role of homework in the daily practice of a middle-school mathematics teacher and her colleagues in Shanghai. It aims to explore how a system of homework activities mediates and engenders a cultural pedagogy characterized by transforming errors into resources for teaching and learning. The transformation itself…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…
