Constructing formal geometry proofs in is an important topic in the mathematics curriculum. But students' difficulties with proof are well documented. This article focuses on proofs that use triangle congruence postulates in US high school geometry. Examining students' proof reasoning in one-on-one task-based interviews, we analyzed students' oral…

Assessing student mathematical knowledge is an important factor in the mathematics learning process because students obtain important feedback to improve their knowledge and learning. Despite the importance of student assessment, several researchers have shown that student grades comprise noncognitive and metacognitive factors and teachers'…

This study is situated within a male-dominated Palestinian-Israeli reality rife with issues of gender privilege. With a purpose to disrupt the status quo in my language classroom and positively affect students' beliefs towards gender injustices, I, as a teacher researcher, designed a unit on gender issues including a book set that would challenge…

We conducted a multisite replication of Yang and Lyster's (2010) study investigating the effects of recasts and prompts on learning English regular and irregular past tense. Our study was conducted with intact high school and vocational school classes in Italy and Bosnia. Our participants were young adolescents (14-15 and 16-17 years old), a…

The purpose of this study was to determine whether there were differences in levels of sentence complexity and grammatical correctness between the spoken and written persuasive language of adolescents with Learning Disabilities (LDs). After viewing short videos providing background information on controversial animal welfare topics, spoken and…

The present study examined the effects of different types of written input on the learning and retention of collocational knowledge. Eighty-three second language (L2) learners from four intact classes were divided into a control group and three treatment groups. The treatment groups were provided with infrequent grammatical collocations embedded…

In this study, I examined how 34 Spanish-speaking English language learners (ELLs) used their linguistic resources (English and Spanish) and language modes (oral and written language) to demonstrate their knowledge of proportional reasoning in a dual language mathematics assessment task. The assessment allows students to see the item in both…

Dual language programs are poised to produce bilingual/biliterate teacher candidates to alleviate bilingual educator shortages. Therefore, in search for ways to support the growing number of Spanish/English dual language programs in Texas, the authors of this paper analyzed the variations of Spanish language and proficiency levels of 9th grade…

As an increasingly popular format of input, the affordances of audio-visual materials have been widely studied. Past research has provided evidence that audio-visual input combined with different captioning strategies could benefit learners in terms of vocabulary learning, listening comprehension, and the development of grammatical knowledge.…

This article reports on what happened when a mathematics teacher at an urban, New Zealand secondary school trialled the use of oral and written language tasks with his Year 9 mathematics students (two classes) as a way of developing their understanding of algebra. Over a period of five weeks, he trialled the use of a range of activities that were…

Six students and six parents were interviewed about the use of Cued Speech (CS) in an inclusive context in Quebec, Canada. The objective of the study was to describe their perceptions of the use of the French version of Cued Speech in high school and to identify factors that could influence these perceptions. The results of the semi-structured…

This study investigated literacy learning in students with specific kinds of language challenges at a specific stage of schooling--transition to high school--when the language requirements of the curriculum can be especially challenging. For this exploratory research, a case study approach was adopted that compared 2 adolescent boys both with…

Adolescent newcomer students bring a wealth of linguistic and cultural resources to their learning environments--resources that become even more dynamic when combined with those of their peers. While a significant body of research has explored students' deployment of multilingual resources through translanguaging, most of this work does not…

This article focuses on the management of students' independent work in the specialty "Journalism" on the subject "Special Foreign Language" in high school through project-based learning, which is one of the most important and modern types of tasks. The goal of this work is theoretically and experimentally proved the…

The study in this article examines and illustrates the intertextual meanings made by a group of high school science students as they embarked on a knowledge building discourse to solve a physics problem. This study is situated in a computer-supported collaborative learning (CSCL) environment designed to support student learning through a science…
