Scientific thinking constitutes a vital component of scientific competencies, crucial for citizens to adapt to the evolving societal landscape. To cultivate students' scientific thinking, teachers should possess an adequate professional knowledge foundation, which encompasses pedagogical content knowledge (PCK). Assessing teachers' PCK of…

We developed a Quantum Mechanics Conceptual Understanding Survey (QMCUS) in this study. The survey was conducted using a quantitative methodology. A multiple-choice survey of 35 questions was administered to 338 undergraduate students. Three experienced quantum mechanics instructors examined the validity of the survey. The reliability of our…

Teaching physical science has been challenging for educators for quite some time, and with the COVID-19 pandemic, the situation has even worsened which made the adoption of blended learning in the different cycles of education only a matter of time. This paradigm requires nevertheless a certain command when it comes to using some specific tools…

Conceptual change is assumed to be a potential teaching pedagogy to prepare the skills for anticipating the 21st century. A quasi-experimental method with pre-and post-test control group design was applied to examine the effectiveness of integrating the 3-2-1 reading technique with refutation text on students' conceptual change of buoyancy. The…

Background: Chi and colleagues have argued that some of the most challenging engineering concepts exhibit properties of emergent systems. However, students often lack a mental framework, or schema, for understanding emergence. Slotta and Chi posited that helping students develop a schema for emergent systems, referred to as schema training, would…

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly…

Spaced repetition has been widely implemented and examined in mobile-assisted word learning as an important learning strategy. However, the nature of spaced repetition by commercial word-learning apps and the factors leading to the favoured mobile-assisted spaced repetition have yet to be investigated in authentic contexts. In this study, we coded…

The objective of this study was to employ a new tool for assessing pragmatic "proficiency" (over "performance") in L2 students and to determine if pragmatic lessons on compliment sequences had a positive impact on L2 Spanish students' intercultural competence. To this end, students at a Midwestern college engaged in live video…

This paper explores the impact of AI applications in adaptive learning on learners with varying levels of Chinese proficiency and diverse learning needs. The study investigates the robustness of VR technology in enhancing Chinese oral proficiency and pragmatic skills among 1st year and 2nd year learners. It compares the established VR app Mondly…

The topic of instructional communication skills of educators is relevant to the learning process, yet the problem exists where many educators are not sufficiently trained in effective instructional communication skills. The outcomes of effective instructional communication skills of educators can enhance communicative cognitive processing,…

The present study addresses a significant but neglected aspect of vocabulary teaching in general and teaching collocations, in particular, which is color term collocations. A significant number of idioms involve use color terms such as blue blood, black death, red tape, black sheep, and yellow press that are significant to study in the context of…

The objective of this study was to employ a new tool for assessing pragmatic "proficiency" (over "performance") in L2 students and to determine if pragmatic lessons on compliment sequences had a positive impact on L2 Spanish students' intercultural competence. To this end, students at a Midwestern college engaged in live video…

Spanish learners engaged in two-way interaction gap tasks where, through social interaction, they identified and defined low-frequency vocabulary. Participants (referred to as actors to differentiate them from task partners) completed two such tasks. Each time, they collaborated with different partners of varying degrees of Spanish proficiency and…

This paper presents the results of a Classroom Action Research (CAR) on the use of Nearpod, an online platform that facilitates the use of interactive teaching material using mobile devices, to conduct a formative assessment in the classroom. There are two aims of this study. First, exploring the effectiveness of using Nearpod to conduct in-class…

The present study sought to evaluate the pragmatic competence of heritage learners of Spanish in regard to compliment sequences and the impact that pragmatic lessons would have on these students. To this end, pre and post tests to assess pragmatic recognition in regard to Spanish compliments were designed by the researchers and completed by the…
