This paper reports the findings of the second year of a four-year empirical research project. Its aim is to modify 'step-by-step' instructions for practical activities in a way that may enable the development of experimental design skills among junior high school learners. Each school year pupils spend six lessons doing practical activities using…

The 21st century technology has advanced to become an accessible beacon of education. The physical boundaries of the chemistry laboratory have expanded with the use of innovative virtual lab simulations despite disparate results from previous investigations of student performance comparing virtual lab simulations with traditional laboratory…

Board games have been used as instructional tools for a wide array of subjects from primary to secondary levels. The present study aimed to develop and apply a novel board game for the instruction of content relating to mole conversion through dimensional analysis in a grade10 class of 29 students. To assess their knowledge prior to and after…

The Next Generation Science Standards encourage students to develop the reasoning and practice skills of scientists. Rather than promoting rote memorization, teachers engage students with real-world phenomena and prompt students to think critically. ChemVLab+ is a series of freely available, online modules that require students to reason like…

Science process skills are the backbone of science, and innovations in this field. It is critical to inculcate such skills among learners at their early stages of learning science. This study reports on how using the mobile phone WhatsApp-supported instructional resources resulted in improvement in students' science process skills in chemistry, in…

The case study-based module on chemical thermodynamics course (ideal and real gases) was developed to fulfill the needs of undergraduate students in online learning during the COVID-19 pandemic. The purpose of this study was to test feasibility of case study-based module. The case study-based module refers to the 4D model (define, design, develop,…

Technology and validation methods for producing biodiesel have been updated and have kept advancing. Creative raw materials used in producing environmentally friendly biodiesels have also attracted interest from scientists. Thus, learning and teaching methods on biodiesel production at the high school level need to be up to date. However, there…

This article describes the implementation of a student-generated open educational resource project into a majors' organic chemistry laboratory. This scaffolded semester-long project was organized into six phases and designed to promote the goals of teaching students about both green chemistry and real-life applications of the reactions covered in…

This paper addresses the incorporation of a scaffolded infographic project into a majors' organic chemistry laboratory. Students were given the freedom to choose their topic with the stipulation that it must be relevant to both organic and green chemistry. This scaffolded project consisted of the following eight phases: (1) summarizing and…

For the past several decades, high-enrollment undergraduate chemistry laboratory experiences have favored traditional approaches involving disparate daily experiments with optimized protocols provided to students. This model often results in poor learning outcomes and low student engagement, and it lacks any attention to scientific inquiry. Here,…

Active participation in project-based learning (PBL) could develop students` knowledge and crucial learning skills across various disciplines. However, the implementation of PBL in the K-12 classroom is usually impeded by the stepby-step PBL cycle. Micro project-based learning (MPBL), which advocates and adheres to the learning principles and…

We developed a comprehensive training module for the undergraduates majoring in chemical education with a simple microfluidic experiment. The students were required to read a scientific reference offered by the instructor, then design and implement a microfluidic experiment for real sample analysis by making some modifications to the method…

Three days into the academic year, the COVID-19 pandemic abruptly led to emergency remote teaching, ERT, of Chemical Experimentation--a revised alternative to the majors' General Chemistry Laboratory at the University of Costa Rica. The course was reoriented to support students' development of nontechnical experimentation skills and scientific…

In delivering chemistry courses by distance, a key challenge is to offer the learner an authentic and meaningful laboratory experience that still provides the rigour required to continue on in science. To satisfy this need, two distance general chemistry laboratory courses appropriate for Bachelor of Science (B.Sc.) students, including chemistry…

In response to a concern about the persistent underachievement in exams of Chemistry students in one school, a pilot study was carried out to see if mentoring-style intervention could improve exam performance. Individual personalised interviews were offered to a class, during which support for the development of the skills and subject knowledge…
