To present the difference in oxidizing strength in concentrated and dilute nitric acid reacting with copper, a simple, facile demonstration of these reactions is designed using a waste plastic bottle, plastic droppers, and syringes, which are costless and easily assembled. This new version can be used to demonstrate the difference in oxidizing…

The process of building a teaching platform for contemporary Chinese literature poses many challenges. Based on big data research, this study was conducted using diversified intelligent analysis technology and theory. Through a fuzzy analytic hierarchy process method and relevant steps regarding intelligent parameter improvement, this study…

In massive open online course (MOOC) environments, computer-based analysis of course reviews enables instructors and course designers to develop intervention strategies and improve instruction to support learners' learning. This study aimed to automatically and effectively identify learners' concerned topics within their written reviews. First, we…

Recent advancements in large language models (LLMs) hold significant promise for improving physics education research that uses machine learning. In this study, we compare the application of various models for conducting a large-scale analysis of written text grounded in a physics education research classification problem: identifying skills in…

A strong predictor of children's language is performance on non-word repetition (NWR) tasks. However, the basis of this relationship remains unknown. Some suggest that NWR tasks measure phonological working memory, which then affects language growth. Others argue that children's knowledge of language/language experience affects NWR performance. A…

As science educators seek innovative methods to engage students, the Culturo-Techno-Contextual Approach (CTCA) has emerged as a promising strategy, particularly for African students. CTCA is a culturally responsive teaching method that integrates culture, technology, and locational context, making science more relatable and meaningful. We assessed…

Research comparing equal and expanding spacing schedules in relation to L2 single words is limited. Moreover, none of the existing studies has examined the learning of formulaic language. The current study aims to address this gap by investigating the impact of equal and expanding intervals on the long-term retention of L2 collocations in…

The coefficient of restitution (COR) for a collision is usually a number between 0 and 1 depending on whether the collision is completely inelastic, or perfectly elastic or something in between. That is the usual situation for colliding spheres or a ball dropped on a horizontal surface. A different situation arises when a bat collides with a ball.…

Many language teachers employ collaborative learning within their classrooms. However, expectations surrounding the efficacy of working collaboratively need to be empirically verified. This study employed dynamic assessment to investigate whether learners who are situated within an undergraduate Qatari EFL context learn second language grammatical…

The assessment process in higher education considers four aspects: assessment agents, procedure, content, and scoring. In this study, we delve into the who. We analyze the role of transversal competence assessment agents in the framework of professional internships in university master's degree programs, comparing the suitability of their…

This study aimed to determine the effect of explain-analysis-doing discussion or known as ex-add learning techniques on critical thinking skills and pedagogic competence of Islamic religious education students at State Islamic University (UIN) Sulthan Thaha Saifuddin Jambi and at UIN Raden Fatah Palembang, Indonesia. The approach used quantitative…

In mixed methods approaches, statistical models are used to identify "nested" cases for intensive, small-n investigation for a range of purposes, including notably the examination of causal mechanisms. This article shows that under a commonsense interpretation of causal effects, large-n models allow no reliable conclusions about effect…

This paper aims to investigate to what extent preschoolers' narrative speech can be affected by the combined use of five narrative elements: narrative framing, narrative basic structure, intertextual hero, plot subversion and image-text interaction. It presents an intervention aiming to teach these elements to an experimental group of…

In carrying out surveys involving sensitive characteristics, randomized response models have been considered among the best techniques since they provide the maximum privacy protection to the respondents and procure honest responses. Over the years, researchers have carried out studies on the estimation of proportions of the population possessing…

Length of the Unused Bed (LUB) methods for scaling sorbers have confusing and complicated pedagogically elements. One method limits feeds to C/C[subscript F] < 0.3; a limitation not stated in the established textbooks. Discussed is a new LUB method with no limitation on the feed C/C[subscript F]. It fixes the pedagogically confusing and…
