In this article we analyze how students reason about linear combinations across multiple digital environments. We present the work of three groups of undergraduate students in the Southeast United States (US) who were considered ready to take linear algebra. The students played the game "Vector Unknown," reflected upon aspects of their…

Genre, defined as a "staged goal-oriented social process" (Martin, 2009), has long stood as a key principle in second-language writing instruction. This article presents the principles underpinning genre theory as it relates to the language curriculum and the five phases of genre-based L2 writing pedagogy. This pedagogy provides the…

Because deficits in executive functions (EFs) characterize most neurodevelopmental disorders, it is appropriate to question the value of EFs for understanding learning disabilities. Two types of studies--those testing whether EFs moderate treatment effects and those testing the direction of effects between EFs and academic skills--are presented to…

To motivate learners to engage in writing courses and help to improve their writing performance, a mobile-game-based collaborative prewriting approach was proposed in this study. A quasi-experiment was implemented by recruiting two classes of non-English major students from a university in northeastern China. Class 1 learned to write under the…

Higher education organizations in countries where English is not the native tongue must function in a multilingual mode, using English as their primary language for scientific exchange and academic publication and relying on the native language for instruction and administration. When operating in a multilingual mode of communication and identity…

The California Community Colleges (CCC) began implementation of AB 705 in fall 2018, ensuring that most students started in transfer-level math rather than a developmental education sequence. The RP Group's Multiple Measures Assessment Project (MMAP) has found that for all student groups, dramatically increasing access to transfer-level math…

This paper examines how different approaches in mathematics education conceptualise the relationship between school mathematics and university mathematics. The approaches considered here include: (a) Klein's elementary mathematics from a higher standpoint; (b) Shulman's transformation of disciplinary subject matter into subject matter for…

This article examines school history textbooks in Afghanistan and investigates the particular ways in which conceptualizations of temporality, history, and the use of calendars contribute toward the construction of the national narrative. It investigates three generations of history textbooks, published between 1998 and 2021 under the Islamic…

Incorporating forensic applications into chemical education serves as an effective strategy for engaging college students and equipping them with the skills necessary to become valuable in the workforce in relevant fields. For instance, learning how to extract controlled substances from biological specimens in a laboratory course is essential for…

This paper reports on a writing programme I started at Bronx Community College to improve academic success among recently immigrated Spanish-speaking students by linking ESL courses to Spanish academic literacy courses within the framework of a learning community. My reflection begins by articulating the pedagogical rationale for looking beyond…

The Crookes radiometer (also known as a light mill) is a fascinating sunlight-powered device, in which a set of vanes is placed inside a glass bulb within which a partial vacuum has been pulled. The vanes then rotate when sunlight shines on the bulb. The reason for the turning of the vanes was subject to intense debate and many students still have…

The "Science of Reading" (SOR) has gained traction due to public media, resulting in a nationwide prioritization of teacher training and changes in the way reading is taught. The nationwide emphasis on the SOR led to new teacher certification requirements in Texas. Although teacher candidates already take a content exam to demonstrate…

The research on mathematical argumentation has mainly adopted a dialectic lens which focuses on understanding the abstract and logical development of reasoning in argumentation. However, this approach may have overlooked other key aspects of mathematical argumentation, including the unfolding of the meaning-making experience and process during…

In the United States, many actors are pushing for the use of grade point average (GPA) as the main placement tool for gatekeeper math and English courses for community college students (Quarles, 2022; Scott-Clayton, 2018; Turk, 2017). One community college system (pseudonymously, SXCC) in a New England state has begun placing students in initial…

The question is whether or not we or any student are allowed to define a measure of variability in some other way that is not written in textbooks and officially approved. We compare the sum of squares of all deviations against the usual sum of squares of deviations from the mean.
