Teacher scaffolding is crucial to promote students' cooperative learning processes, but little is known about the cognitive attention underlying teachers' scaffolding behavior. This study aims to investigate the scaffolding behavior teachers exhibit while intervening in students' cooperative learning and to explore the relation between teachers'…

When justifying a mathematical statement, textbooks often interweave several instances of justification, creating, what we term, "paths of justification." This study aims to characterize the paths of justification of mathematical statements that are offered in eight 7th grade Israeli mathematics textbooks. The study attended to context…

This research compares the use of triadic dialogue and translanguaging in two multilingual grade seven classrooms where algebra is taught in a foreign language. Ten lessons in one classroom that involve teaching properties and seven lessons in another classroom that involve teaching conventions were video- and audio-recoded and then transcribed.…

The literature has amply shown that primary and secondary school students have difficulties in understanding rational number size. Many of these difficulties are explained by the natural number bias or the use of other incorrect reasoning such as gap thinking. However, in many studies, these types of reasoning have been inferred from comparing…

This study investigated gender disparities in students' science motivational beliefs, conceptualized as self-concept and intrinsic value, from Grades 4 to 8 in 22 countries. The gender-specific relation between science motivational beliefs and achievement was also scrutinized. Data from the 2011 and 2015 national cohorts of the Trends in…

The quality of curriculum resources and teaching practices can constrain or promote students' opportunities for mathematics learning, in particular, students with diverse language proficiency. The video study investigates 18 classes that all used the same curriculum resources aimed at developing 367 seventh graders' conceptual understanding of…

We investigated the cognitive demand of the exercise problems that middle school students from Nepal are expected to complete. The middle school (grades 6, 7, and 8) mathematics textbooks examined in this study were published and distributed by the government of Nepal. Our data set consisted of textbooks that are currently in use in public schools…

Attending to the whole unit that a number refers to in a mathematical problem situation and showing flexibility in coordinating different units are foundational for mathematical understanding. In this study, we explored teachers' attention to and flexibility with referent units in situations involving fractions and fraction multiplication. Using…

This article explores three attributes of teachers' understanding of fraction magnitude: the accuracy and reasonableness of teachers' estimations in response to fraction arithmetic tasks as well as the alignment of the estimation strategies they used with the concept of fraction magnitude. The data were collected from a national sample of…

The purpose of this study is to investigate how languages in a multilingual classroom come to participate in the objectification process in the context of pattern generalization. Data came from the transcription of 10 videotaped sessions in grade 7. A mixed quantitative-qualitative approach was adopted for the analysis. The significance of triadic…

Reading comprehension is an essential skill for learning in general and in science classes. Problems with reading comprehension might hinder students' participation in learning science. Text in science includes specific language features that distinguishes it from narrative text, so should reading instruction be part of teaching science? The…

The history of science (HOS) has played an important role in science curricula for teaching about science. However, historical information in science textbooks is often de-contextualized, coupled with limited class time and teaching barriers, and thus fails to help students understand the dynamic process of scientific development. This research…

Students with high reading proficiency typically achieve better results in science assessments, indicating the importance of reading proficiency. Since the process of reading is a complex interaction between properties of a text and a reader, the linguistic demands of a text might affect text comprehension. Certain linguistic features, such as…

The aim of this study is to investigate the effectiveness of the common knowledge construction model (CKCM)-based instruction on academic achievement and 7th grade students' views about the nature of science (NOS) presented in electrical energy unit at schools of different socio-economic levels. In accordance with this purpose, three secondary…

The aim of the current study was to investigate the statistical literacy of seventh grade students regarding the concepts of average and variation on bar and line graphs presented in alternative real-life contexts. To this end, the statistical literacy levels of the seventh grade students were initially determined. Subsequently, definitions,…
