This study investigates how 11- to 12-year-old students construct data-based decision trees using data cards for classification purposes. We examine the students' heuristics and reasoning during this process. The research is based on an eight-week teaching unit during which students labeled data, built decision trees, and assessed them using test…

Inspired by a "whole child" framing, the current study takes a "whole classroom" perspective to consider classroom practice. Study aims included: (1) presenting a systematic video-based observational coding strategy to concurrently consider practice domains that have implications for learning--cognitive instruction, classroom…

The aim of this study is to investigate the end-of-unit evaluation questions in 5th grade primary school science workbook according to dimensions of the Revised Bloom's Taxonomy (RBT). For that purpose, 191 end-of-unit evaluation questions of 5th grade science workbook which is approved by the Republic of Turkey -the Ministry of National…

Proportional reasoning is a key topic both at school and in everyday life. However, students are often misled by their preconceptions regarding proportions. Our hypothesis is that these limitations can be mitigated by working on alternative ways of categorizing situations that enable more adequate inferences. Multiple categorization triggers…

Prior studies suggest that struggling to make sense of mathematics is a necessary component of learning mathematics with understanding. Little research exists, however, on what the struggles look like for middle school students and how they can be productive. This exploratory case study, which used episodes as units of analysis, examined 186…

Linear algebra is one of the most challenging topics to learn and teach in many countries. To facilitate the teaching and learning of linear algebra, priority should be given to epistemologically analyze the concepts that the undergraduate students have difficulty in conceptualizing and to define their ways of reasoning in linear algebra. After…

Coders used real-time focal-child sampling methods to observe the playground behavior and victimization experiences of 600 third to sixth grade youth. Person-centered analyses yielded three profiles that specified aggressive function (reactive, proactive) and form (direct, indirect), and conformed to social-information-processing functional…

The results of Romanian school students in Science PISA and TIMSS testings have been and continue to be systematically slack. In the present paper we intend to do a comparative analysis of Science curriculum TIMSS 2007 and Romanian Science school curricula of 4th and 8th grades. This analysis, based on Bloom's taxonomy of cognitive domain,…

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…
