The COVID-19 pandemic presented significant challenges for both students and educators, particularly because of the virtualization of classes and the consequent lack of practical sessions following the closure of laboratories and experimental fields in universities. The absence of interaction among students and practical classes led to a…

This descriptive study focuses on using voice activity detection (VAD) algorithms to extract student speech data in order to better understand the collaboration of small group work and the impact of teaching assistant (TA) interventions in undergraduate engineering discussion sections. Audio data were recorded from individual students wearing…

The main objective of this study is to revise and validate the assessment of self-presentation skills of middle school students. The assessment is based on existing self-assessment scales and adaptively modified for a more accurate assessment of middle school students' self-presentation skills.

Pedagogical content knowledge (PCK) has framed teacher education for decades, despite the difficulty of demonstrating that teacher preparation effectively develops PCK. Social studies educators have been especially wary of PCK, but their critiques have primarily challenged what knowledge is valued rather than its model of how teachers learn. This…

Although researchers recognize the importance of discussing support for math learning within online learning communities, there is a lack of relevant network classifying methods and analyses at the group level to understand the behavioral differences between groups with varying levels of activity, including their mathematical literacies. In this…

Interaction is the distinctive feature of focus groups, yet little attention has been devoted to understanding techniques for enhancing the quality of interactions. We argue that using a quantitative survey instrument with focus groups has specific benefits beyond traditional open-ended topic lists or questions. We describe particular features of…

Countercurrent multiplication (CCM) is widely accepted as the mechanism for the generation of the corticopapillary osmotic gradient in the outer medulla of mammalian kidneys. However, several issues in the literature cause the current explanations of CCM to be inefficient and incomplete. As a result, it is challenging to clearly explain CCM in…

Active learning, a common practice in higher education, has been shown to promote higher order thinking and skills. Class discussions have been chosen to be the medium to incorporate active learning in schools' curriculum. However, the rate of class participation could be low for certain courses. Literature has shown that the fear of negative…

While several studies support the appropriateness of tasks delivered through Spoken Dialog Systems (SDSs) for L2 oral communication assessment, few studies have explored the construct of interactional competence (IC) as measured by such tasks. This study aims to address this gap in the literature by investigating the use of IC features by high-…

This current study measured the impact of a one-time semester-long course-based civic engagement activity on student learning and participant impact, particularly participants' willingness to engage in community dialogue and promote awareness of social justice issues within their communities. The service-learning project involved on-campus and…

In the late 1990s, linguist Deborah Tannen argued that America had become an "argument culture" characterized by an adversarial frame of mind when approaching the world and the people in it. Recent events appear to have added apocalyptic fears (not entirely unfounded) to our adversarial approach. How can we talk to each other in such a…

This research used qualitative netnography to examine the use of Duolingo German discussion boards among users of varying levels of engagement. The sample contained six participants of various levels of engagement. The criteria for selecting participants were based on usage counts in the discussion board community. This study aimed to examine…

Children often prefer nonfiction to fiction books but historically, teachers have neglected nonfiction books during reads alouds. The present study examined how young readers collectively make meaning of nonfiction picturebooks with the help of the teacher and their peers during a whole group interactive read-aloud in one kindergarten classroom.…

Employing membership categorization analysis and conversation analysis, we uncover how students performing classroom discussion tasks for language learning locally ascribe themselves and others to various identity categories within single discussion activities. Data consist of 126 hours of video-recorded small-group discussions for second language…

This study uses document, observation, and interview to analyze ten Taiwanese elementary school English teachers' practice and exercise of leadership among other colleagues during professional dialogue and to examine what influenced the practice of leadership. This study has the following major findings. First, participants' leadership was mainly…
