Purpose: The present study examined the effect of Directed Activity Related to Texts (DARTs) and gender on student achievement in qualitative analysis in chemistry. It focused on the qualitative analysis component of the Chemistry course, which for students has been perceived as being the most difficult aspect of their mastery of the subject.…

This paper presents an intervention aiming to promote students' learning by enhancing their interest in the concept of energy. Junior high school students' learning and interest is evaluated after engaging in activities on work and energy. The intervention integrated hands-on and simulated experiments included a structured series of guided…

The COVID-19 pandemic has forced educational institutions to adjust their learning process to distance education or online learning. This paper explains how to teach optics during the COVID-19 pandemic by implementing project-based learning that can be supervised online. Students are instructed to design, characterize, and optimize droplet lenses…

The practical work described here is designed for third-year bachelor students in Life Sciences attending a kidney physiology course. It illustrates how urinary biochemistry can be used for a medical diagnosis. Students have to measure glucose, proteins, and creatinine concentrations in three simulated urine samples. First, they independently…

A problem-based learning (PBL) methodology was implemented to a project, whose main objectives were to discuss and apply the Twelve Principles of Green Chemistry to the study of poly(vinyl alcohol)'s cross-linking reaction with dicarboxylic acids. The five participating students were oriented to be responsible for their own learning and the…

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the correlations of science classroom teachings with eighth graders' science…

This study examined the roles of gender and STEM major status as predictors of performance in formulating a research question and designing experiment among 70 undergraduate Taiwanese college students participating in inquiry-based learning (IBL). Student participants in this study were involved in discrepant demonstrations of scientific events…

Growing evidence has come to suggest that model-based inquiry can improve student learning outcomes and attitudes toward STEM in the biological sciences and beyond. In our introductory biology laboratory course that focuses on cellular and molecular biology, we introduced model-based inquiry (MBI) labs to create a more student-focused course that…

The laboratory practice "Primary culture and directional differentiation of rat bone marrow mesenchymal stem cells (BMSCs)" is part of a required course for sophomore medical students at Tongji university, which has been conducted since 2012. Blended learning has been widely applied in medical courses. Based on a student-centered…

Although international school systems and resources can differ from those in the UK, it is always useful to have an informed worldview of practice in primary science. The COVID-19 pandemic has inevitably changed the ways in which pupils around the world have access to knowledge. Furthermore, it has changed the ways in which teachers globally…

It is commonly accepted that learners gain better understanding of science concepts when they perform 'hands-on' experiments in the lab. However, the lack of lab infrastructure, particularly in most rural schools, negatively affects the teaching of science. With the increasing potential of ICT to education, virtual laboratories (VL) have emerged…

The nature of science describes what science is, how it works, and its interactions with society under the perspectives of philosophy, history, sociology, and psychology of science. Understanding it is an essential aspect of scientific literacy. Given the critical role that school textbooks hold, considering what is taught and how it is taught in…

Research-based blended learning (RBBL) allows students to be part of an authentic scientific discovery process. In this study, students' perception and motivation of the RBBL coupled with Scrum methodology in a third-year polytechnic chemistry laboratory course were investigated. Results showed that the scaffolded approach, designed referencing…

In this paper we designed a STEM outreach program with a modular tissue engineering education tool (we refer to as "modular cyclic-stretch device") to engage high school students in STEM hands-on activities. Using simple machines such as gears and rotating cams, students were able to build a custom device to apply cyclic stretch to…

The COVID-19 outbreak has created turbulence and uncertainty into multiple aspects of life in countries around the world. In China, the pandemic continues to pose a great challenge to the nature of traditional in-class education in schools. Chinese education has faced the difficult decision of whether to resume in-person teaching in an…
