Background: Although sound is an everyday phenomenon that we hear about constantly, numerous studies have reported that students often exhibit learning difficulties in understanding this subject. Only a few studies have proposed programs involving practical learning experiments to provide students with solid conceptual knowledge. Moreover, little…

Despite an extensive amount of research examining students' perceptions of alternative laboratory experiences, little focus has been aimed at the perceptions of adult learners. This two-phase mixed-methods study investigated the preferred at-home laboratory experience, and the factors that played a significant role in the user experiences, of…

Chemistry is considered a difficult subject by most students. Its difficulty lies in Chemistry's complex and abstract nature. This highly abstract nature requires constant interplay and coordination between the macroscopic, particulate, and symbolic representations. Experts can successfully navigate the various representations without overloading…

The aim of this study was to develop a science experimental guidebook for the mainstreamed students with learning disabilities and investigate its effect on their conceptual understanding of physical events. Through case study research methodology, the sample of the study consisted of 12 mainstreamed students with learning disabilities. To collect…

Animal dissection is practiced to varying degrees around the world and is particularly prevalent in North America throughout all levels of education. However, a growing number of studies suggest that nonanimal teaching methods (NAMs) (e.g., virtual anatomy tools and three-dimensional models) are better for achieving learning goals compared to…

This research examines the effectiveness of the STEM Supported Inquiry-Based Learning Approach on the conceptual understanding of 7th graders. In the study, a mixed-method design was adopted. The research was carried out with 64 students studying in a secondary school. The study used a Conceptual Understanding Test (CUT) and an Interview Form as…

Worksheets are common in science classrooms with an aim to support pupils' meaning-making, e.g., for guiding them in performing hands-on activities and documenting their experiences of such activities. Yet, there have been few systematic studies of pupils' disciplinary representations in worksheets. Drawing on systemic functional linguistics, we…

Because of the COVID-19 pandemic, most courses at universities in many countries transitioned to a remote format for the 2020-21 academic year. This presented additional challenges for courses taught with a hands-on component. Here we describe the implementation of a take-home activity kit and laboratory demonstrations to facilitate hands-on…

We have developed a multivariate and multidisciplinary lab experiment on the synthesis of alginate hydrogel beads of various sizes and dye encapsulation for upper-division undergraduate and graduate students. This experiment introduces students to several common concepts in polymer chemistry, materials science, and drug delivery. The experiment…

An upper-division undergraduate- or graduate-level laboratory experiment, challenging students to identify bovine serum albumin, equine myoglobin, bovine calmodulin, and bovine cytochrome c, uses four methods of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS): linear positive, in-source decay, peptide…

While some might argue that lessons such as this cater towards nonformal education, teachers should not be deterred from integrating these lessons into their formal classrooms. Nonformal lesson plans--including their structures and techniques--can and should be integrated into formal classroom settings. Many nonformal activities are easy to…

BYOL (Bring Your Own Lime), a novel laboratory experiment, is introduced in this paper. Students are encouraged to bring affordable household and grocery store chemicals into the classroom. The Bring Your Own Chemical (BYOC) concept demonstrates to students that food and household products are chemicals too. Citruses are often used to highlight…

Learners' curiosity is among the affective domains of learning that has a great potential to take learning to higher levels and meet the demands of the 21st-century teaching and learning process. This paper assesses how hands-on activities performed using learning materials from learners' immediate environment can enhance learners' curiosity in…

This study compares three pre-collegiate teacher professional learning and development (PLD) integrated science, technology, engineering, and mathematics (STEM) experiences framed in astronomy. The study is set in the western United States (USA) and involves 60 pre-collegiate teachers (in the USA these are K-12 teachers) over the course of three…

Laboratory classes are a cornerstone of physiology education, enabling students to develop essential knowledge and skills. Recent moves toward utilizing blended options to support face-to-face classes with online materials are beneficial, but using solely online classes may not produce similar learning gains. During 2020, the global pandemic meant…
