Titration is an important experimental skill that every chemistry educator and learner must master. Titration is often the method of choice in the science laboratory courses in secondary and postsecondary schools. During acid-base titration, chemistry learners are always told about salt formation. However, a practical visualization of the salt…

Both nanopore-based DNA sequencing and CRISPR/Cas-based gene editing represent groundbreaking innovations in molecular biology and genomics, offering unprecedented insights into and tools for working with genetic information. For students, reading, editing, and even writing DNA will be part of their everyday life. We have developed a laboratory…

The diversity of scientific methods has received widespread recognition in recent years. The purpose of this review is to analyze the changes in the representation of laboratory work in Chinese senior high school chemistry textbooks in the past 30 years from the perspective of the diversity of scientific methods. This study was based on Brandon's…

Although most teachers recognize the importance of taking investigative, open-ended approaches to students' learning experiences, implementing them in high school classes can be challenging for teachers. In this work, we analyzed data from multiple sources from a teaching Community of Practice (CoP) to investigate (a) barriers to taking an…

Increasingly, science teachers are seeking phenomena that will allow them to explore both scientific content and socially relevant issues. The authors describe a series of lessons that (1) model the exoneration of wrongly convicted individuals using the science of DNA analysis and (2) contextualize individual cases within a larger system where…

Internationally, second level curriculum policy for STEM education is concentrating its efforts on promoting curriculum-making pedagogies, with enquiry-based teaching and learning at the forefront of this change. Policy aspirations have not translated well into practice, evidenced by science practical lessons consistently being delivered as…

Contemporary science teaching pedagogy in Namibia places a strong emphasis on fostering inquiry-based instruction and practical work in secondary school science education. In recent years, there has been a growing recognition of the need to move beyond traditional, rote-based methods towards more learner-centred approaches that encourage active…

It is difficult for students to learn the concepts of chemical laboratory safety education from actual experiences because the traditional teaching model prohibits students from performing dangerous operations. Therefore, this study develops a novel mixed reality-based chemistry experiment learning system (MRCELS) to allow learners to conduct…

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…

Increasing public concern over the use of animal dissection in education is driving development and testing of alternatives to animal use. Clay modeling has proven successful in achieving comparable or superior learning at postsecondary levels, but it has not yet been tested at secondary levels. This study tested the effectiveness and appeal of…

When the COVID-19 pandemic struck in 2020, many schools made the decision to cancel face-to-face classes and move instruction online. To better understand how the pandemic affected science educators' plans to conduct classroom animal dissection exercises, we conducted a nationwide survey of biology teachers (n = 2131) and asked about their…

The study was conducted to compare the performance of students working in chemistry laboratory with those working in chemistry laboratory supplemented with simulations at secondary school level. The study was experimental in nature and post-test only control group design was used. The sample comprised of 55 males and 60 female students and 02…

Due to the lack of qualified agricultural education teachers needed to fill yearly vacancies on the secondary school level, educators at Texas Tech University conducted a longitudinal study concerning how student teachers spend their time during their student teaching experience in an attempt to identify if this time spent has an impact on the…

The study aimed to explore Lower Secondary School curriculum of Life Sciences, in Morocco, to establish the current status of animal use and the extent at which it is a curriculum requirement for the introduction of the prescribed concepts and objectives. Two questionnaires were developed and administered to teachers and students to assess their…

In biology education which is an inseparable discipline of medical and veterinary education, it is of great importance that enabling students to make practice in real conditions and gain knowledge and skills related to their professional fields during their education. It is necessary to adapt the new technologies rapidly to education rather than…
