The main purpose of the current study is modifying students' daily drinking water and managing waste water through modelling activities as context and modelling cycle as tool. In this study, 12 students (13-14 years old) from the lower secondary school were participated. These students were participated in two sessions (60 minutes) each week for…

This research aims to have an overview of the effectiveness of the "Sabilulungan" culture-based group discussion model assisted by Video-based learning (VBL) to increase the motivation and learning achievement of Tri Mulya Middle School students after the COVID-19 pandemic. The research subjects were Civics students (n=36), 8th grade…

We study the usage of a self-guided online tutoring platform called Algebra Nation, which is widely by middle school and high school students who take the End-of-Course Algebra I exam at the end of the school year. This article aims to study how the platform contributes to increasing students' exam scores by examining users' logs over a three year…

The present study investigates the use of authentic texts (fiction and non-fiction) in 180 video-recorded language arts lessons across 46 secondary classrooms in Norway. It assesses how the texts are used and what kind of language arts-related activities and discourses students are engaging in. The study finds that a majority of the lessons do not…

In this study we extend our prior exploration focused on the extent to which middle school teachers appropriately identified proportional situations and whether there were relationships between attributes of the teachers and their ability to identify proportional situations. For this study, we analyzed both a larger dataset (n = 32) and two…

Mathematical problem solving typically involves manipulating visual symbols (e.g., equations), and prior research suggests that those symbols serve as diagrammatic representations (e.g., Landy & Goldstone, 2010). The present work examines the ways that instructional design of student engagement with these diagrammatic representations may…

In this study we investigated eighth grade students' informal justification for the circle area formula to expand accounts of the measurement knowledge for middle-school age students. Data were collected during three paired interviews of a three-year teaching experiment. Here we describe schemes students exhibited as they operated on measurement…

Increased attention to the relationships between affect and learning has led to the development of machine-learned models that are able to identify students' affective states in computerized learning environments. Data for these affect detectors have been collected from multiple modalities including physical sensors, dialogue logs, and logs of…

Middle Years students often do not see mathematics as useful. Authentic and real mathematics tasks and artefacts are frequently advocated as arresting this situation. However, often such experiences are contrived and lack authenticity. This paper reports on how a group of Middle Years students used mathematics and technology to engage in a real…

The use of video iPods in middle schools was explored through research in two social studies classrooms. This study measured achievement differences in Spring 2007 between two groups of eighth-grade social studies classrooms. Groups were chosen for similarity between numbers of IEP's and/or 504 classifications, and relative class size. Both groups…
