This is one of the first studies to evaluate the impact of computer-based individualized instruction in a developing country. We randomly assigned 1,528 students in grades 6-8 in 15 "model" public schools in Rajasthan, India who were using a computer-adaptive learning software to: a control group, in which they were only able to access…

Previous research has highlighted the importance of social relationships in mathematical group work while working on modelling activities. This study analyses the interaction of sixth-grade students in Primary Education (11 to 12 years old) carrying out a modelling task in groups with a Fermi problem used as the modelling activity. The focus of…

The use of a pedagogical approach mediated transfer with the bridging method has been successful in facilitating the transitions from block-based to text-based programming languages. Nevertheless, there is a lack of research addressing the impact of this transfer on programming misconceptions during the transition. The way programming concepts are…

This study analyzed the comprehension strategies and visuals in two science textbook series for grades 6, 7, and 8 as means of better understanding a core element of the ecological component of science literacy. The iScience [Biggs et al. in iScience (Grade 6), McGraw-Hill, 2015a, iScience (Grade 7), McGraw-Hill, 2015b, iScience (Grade 7),…

We examined the effects of a text-based argument writing intervention, "Triple Q," on argument writing skills in a cluster-randomized trial where groups of middle schools were assigned to conditions within school-level SES blocks. The intervention comprised three 15-day units. Students read and discussed argument texts representing…

This study investigated the effect of a paper folding activity prepared to develop the sixth-grade students' concept definitions and images of parallelism and perpendicularity concepts. The study also examined how the concept definition and images changed after the paper folding activity. A combination of quantitative and qualitative methods was…

Learning engagement is malleable to environmental change. An important learning environment created by teacher-student interactions is perceived teacher autonomy support, which may trigger learning engagement directly and/or indirectly by enhancing academic self-efficacy. In this study, we apply a network approach to explore the relationships…

The present study aimed to examine children's and adults' performance and strategies in volume estimations. Three tasks were designed and presented to 40 adults and 40 6th grade children who were asked to estimate: (a) the number of unit measures (bricks/rice spoons) that may be put in a container, (b) the quantity of bricks/rice, between two…

The lesson described in this article was developed and taught by a team of mathematics educators and physical therapists, with the shared goal of broadening students' perception of how mathematics concepts are applied in the real world. This lesson gives students authentic experience with the Gait Speed Test as a physical therapist would…

In this article, the authors discuss a month-long research study where sixth grade students researched three women for the half-century after the U.S. Civil War War that worked to change their respective communities to address public issues: Jane Addams, Clara Lemlich, and Ida B. Wells. The sixth graders read a picture book for each of the three…

Generalization is one of the core aspects of algebraic thinking, and research literature points to the importance of objectification when generalizing mathematical discourses. To increase the field's understanding of the objectification process in various algebra discourses, our study analyses Grade 6 teachers' use of words, symbols, routines and…

Despite the wealth of knowledge about the impact of bullying victimization, information gaps exist about how traditional and cyber bullying in early adolescence is associated with emotional wellbeing, namely, indicators of positive wellbeing. Therefore, this study investigated associations between different types of bullying victimization and…

Instructional designs that include two or more artifacts (digital manipulatives, tables, graphs) have shown to support students' development of reasoning about covarying quantities. However, research often neglects how this development occurs from the student point of view during the interactions with these artifacts. An analysis from this lens…

In this article, we address a call by Thompson and Carlson to directly contribute to defining the variation of students' reasoning about varying quantities. We show that students as young as in sixth grade can engage in complex forms of reasoning about multiple quantities in contexts that involve exploring science phenomena using interactive…

Purpose: The teacher role in the classroom can explain important aspects of the student's school experience. The teacher-student relationship, a central dimension of social capital, influences students' engagement, and the teaching style plays an important role in student outcomes. But there is scarce literature that links teaching styles to…
