This study explores multilingual study guidance (MSG) teachers design for learning and the potential of immersive and interactive Virtual Reality (VR) technology to support students' development of disciplinary knowledge through multilingual conceptual learning. Part of a co-design research project, the study draws on two teachers' didactical…

With the increasing technology integration practices in education, the adoption of computer simulations to teach conceptual understanding of science concepts is widely accepted by educators across the globe. To understand the connections between learners' engagement and satisfaction with simulations for science learning and their learning styles,…

The sudden COVID-19 outbreak has obstructed the conventional method of teaching causing a mandated shift to virtual platforms. A developing country like India which predominantly depended on conventional methods of teaching and learning in the pre-COVID era is gradually gaining success in effectively transitioning into virtual classrooms with the…

Student evaluations of teaching (SETs) are commonly used in performance evaluations of university faculty. However, evidence regarding the association of SETs to student learning has been inconsistent. One way to assess the connection between SETs and actual learning is to compare SETs in the first course in a sequence to student performance in…

Many researchers have reported that bridging analogies can productively support students' scientific meaning-making. How this can be understood semiotically is, however, not well understood. This research followed an ethnographic case study approach to investigate Year 11 students meaning-making through a process of transduction (Kress, 2000;…

A good number of instructional strategies are identified to help students overcome their learning difficulties in the mole concept. However, Ghanaian senior high school students continue to have difficulties in the mole concept. Hence, there was the need to examine the perceived nature of learning the mole concept in the perspectives of male and…

The purpose of this research is to determine the conceptual understanding of pre-service science teachers about "Colligative properties", which are aimed to be taught within the scope of Chemistry-II course, within the framework of the argumentation-supported problem based learning (AS-PBL) method. The study, in which 24 pre-service…

The ability to collaborate with culturally diverse groups is essential, not only to further scientific knowledge but also to solve complex global problems. However, not all students have opportunities to develop intercultural competencies through study abroad programs, due to various issues such as cost, rigid curriculum, and unrelated field of…

An online chemistry of art course was developed for K-12 teachers enrolled in a Master of Education in Interdisciplinary STEM Education program. This course focused on the chemistry involved in the preparation of artists' materials, art, and the authentication of art and artifacts. The specific course topics addressed safety in creating art; the…

Introductory chemistry courses tend to suffer from high failure rates. Success in an introductory course has been linked to how students approach learning. The aim of this study was to explore how students' learning approach was related to their success in the introductory chemistry courses measured by the ACS exam and the final course grade.…

A novel undergraduate analytical chemistry experiment involving the identification and quantification of linalool in essential oils was developed. The experiment uses the internal standard method with headspace solid phase microextraction (SPME) and gas chromatography--mass spectrometry (GC-MS). This method is applicable to any linalool-containing…

The unforeseen COVID-19 pandemic forced educational institutions to shift to a remote or distance-learning mode. As a result, classes were offered online, and this shift in teaching modality presented great challenges, especially in teaching laboratory courses. While several options are available, we evaluated the use of (i) videos of lab…

The schoolyard as a setting for teaching and learning is rarely the focus of chemistry education. Therefore, a chemistry unit combining activities in the classroom and the schoolyard was designed to support pre-service teachers'(PSTs) learning of redox chemistry. This study was conducted to investigate the PSTs' talk about redox chemistry as they…

This communication describes an activity where upper-level chemistry students explore the determinability of rate constant values without concentration dependences (k[subscript true]) related to a solvent-ligand exchange in a transition metal carbonyl complex. By performing a series of multivariable linear regression (MVLR) analyses of…

Cola beverages are widely consumed and popular among students; they can be used as safe reagents to replace toxic chemical dyes. In this study, a safe and improved experiment is described, which successfully demonstrates Beer's law and adsorption process using activated carbon as the adsorbent and cola as the adsorbate. The results of this study…
