To remain globally competitive, education in the United States must focus on retaining students in science, technology, engineering, and mathematics (STEM). As laboratory courses have the potential to be powerful attractors or deterrents to a field, developing effective laboratory pedagogies is important to retain students in STEM. A course-based…

A drug discovery project has been successfully implemented in an advanced undergraduate organic chemistry laboratory. In the laboratory, a five-step synthetic sequence is used to prepare five analogues of 13-phenyl-1-tridecanol. These compounds are key precursors in the synthesis of 2-oxo-14-phenyltetradecanes. This class of compounds, isolated…

A straightforward procedure for the synthesis of (Ph[subscript 3]P)[subscript 3]CuCF[subscript 3], a robust, air-stable trifluoromethylating agent, is reported herein. This preparation can be completed in a single 3 h laboratory session and typically provides ample yields (~79--86%) and high purity (>90%). The target complex is characterized by…

The study implements and investigates an innovative learning approach that incorporates Flipped Classroom (FC) methodologies and electronic assessment (e-assessment) in Context-Based Learning (CBL) in chemistry among middle school students. The study incorporated mixed methods strategies and (a) examined learners' attitudes toward and perceptions…

Asking students to explain why phenomena occur at a molecular level is vital to increasing their understanding of chemistry concepts. One way to elicit students' mechanistic reasoning and guide construction of knowledge is through Writing-to-Learn (WTL), which is a promising approach for students in organic chemistry courses. In the design of WTL…

This study aims to determine the cognitive structures of students at different educational levels (8th grade and 12th grade) related to acid-base chemistry. The research was designed as a case study and structured in two stages. The first stage analyzed concepts related to acid-base chemistry and their direction and strength in students' knowledge…

Context-based learning (CBL) environments are widely used in science education to create authentic learning opportunities. Contexts can be authentic through their relation to everyday life, to uncommon scientific phenomena, or to the chemical laboratory. Previous research revealed that students choose contexts that are authentic in different ways…

This study explored Indonesian prospective teachers' views on the adapted (including global socio-scientific issues) and revisited (including local socio-scientific issues) versions of the scientific habits of mind (SHOM) scale and compared their SHOM levels concerning teacher education programs and grades. The sample of the study consisted of…

This paper examines the findings obtained in a chemistry laboratory course provided through online hands-on activities during the pandemic. Case study design, one of the qualitative research methods, was used. The data collection period was 8 weeks. The study was carried out with 16 third-year pre-service science teachers within the scope of a…

Lack of proper laboratories and inadequate facilities have become some of the factors affecting chemistry practical in Nigeria which therefore affects students' performance. While there were many studies conducted on the effectiveness of mobile learning, literature remains very scarce in the Nigerian context. In order to tackle this problem, using…

Embodied cognition posits that physical interactions with the environment play a crucial role in learning, including complex, abstract concepts in STEM disciplines. This is relevant for deaf and hard-of-hearing (DHH) learners who often utilize sign language, which is a naturally embodied, visuospatial mode of communication. My dissertation…

Background: Educational board games have been receiving attention from educators in recent years. Designing the rules of board games based on cognitive theory, and further analysing educational board games from more dimensions are important issues that warrant further study. Purpose: The research designed a board game called Chemistry Story to…

Recently, scholars have suggested a co-design collaboration with instructors and students to effectively implement formative assessment (FA) practices because it ensures a high-quality design that considers users' needs, values, and goals in a specific learning context. This study examines the effect of co-designed FA practices, in which…

Providing students with feedback on their performance is a critical part of enhancing student learning in chemistry and is often integrated into homework assignments, quizzes, and exams. However, not all feedback is created equal, and the type of feedback the student receives can dramatically alter the utility of the feedback to reinforce correct…

Numerous studies have delved into the application of augmented reality (AR) in chemistry education, focusing on specific topics, equipment requirements, and advantages. However, there remains a notable dearth of research examining the evolutionary characteristics of AR in this context. This study, employing bibliometric analysis on 66 articles…
