This study aimed to examine the effect of problem-based learning (PBL) in developing science process skills (SPS) and learning achievement on the topic of 'Safety in Our Environment' in secondary schools in Tanzania. The study employed a quasi-experimental design. The participants for the study were Form One 'Stream E' students in the experimental…

General chemistry laboratories are a core requirement for nearly all STEM (Science, Technology, Engineering, and Mathematics) majors and have the greatest breadth in disciplines and audience of any STEM course at a university. A bioremediation Course-based Undergraduate Research Experience (CURE) for first-year undergraduate students was developed…

Recently, two-dimensional (2D) nanostructures, such as graphene and few-layer MoS[subscript 2], have been applied to wide fields based on their intriguing performances, and they contribute to developments of clean energy, biomedicine, and environmental protection. The synthesis of 2D nanostructures involves chemistry, materials, and…

Highlighting the interdisciplinary nature of research, we present a series of experiments for undergraduate lab courses that teach the principles of preparative ion exchange chromatography and flame emission spectroscopy. Through these inquiry-based experiments, the students learn about experimental design and instrument limitations, naturally…

The Australian science curriculum is intended to enable school students to develop an understanding and curiosity about the way that science can assist them in making sense of the physical and technological world. In addition to understanding and communicating scientific knowledge and using inquiry processes, students also need to develop the…

Background/purpose: This study aimed to investigate the effectiveness of a computerized instructional module based on artificial intelligence in acquiring scientific concepts and developing critical thinking among seventh-grade female students. Materials/methods: To achieve the study's objectives, an AI-based computerized instructional module was…

Raising scientifically literate citizens has been the main concern of the science education community. Socioscientific issues (SSIs) provide a context to facilitate individuals to expand their epistemic understanding and develop scientific reasoning skills such as evidence-based argumentation and consensus building. In this qualitative research,…

Introduction: Undergraduate research experiences prepare students for graduate training or employment. Statement of problem: At many teaching-intensive universities, there is a greater demand for research experiences than there are independent study opportunities. Students from typically underrepresented backgrounds may also be unaware of a…

Flow cytometry has become an important tool in the fields of veterinary, medicine, and biological sciences in general. However, in the introductory and even in advanced university degree courses, students do not have many opportunities to be in contact with this type of technology. This situation motivated us to design a simple and inexpensive…

This study developed the Investigable Questioning Formulation Technique (IQFT) protocol to formulate investigable questions by following the procedures of design-based research. As guiding heuristics, the protocol used two provisional design principles based on teaching experience and previous studies that have applied tools for formulating…

In recent decades, enhancing scientific literacy has been the ultimate goal of science education worldwide. This effort aims to develop the skills by individuals to cope with the challenges of the modern world, which requires scientific knowledge and thinking. This research study aimed to investigate and compare the scientific literacy level of…

Reflection on current practices is key to the transformation of teachers into reflexive practitioners. This study describes how design thinking was integrated in Schön's 'reflection in and on' model, to transform traditional teaching of Biology into constructivist learning. As a first step, the reflection model was used to identify limitations in…

Systems thinking is a powerful concept in biology which can help students understand how the diversity of contexts in the biology curriculum all have similar underlying characteristics. However, it is not currently a common feature in secondary education as it is not part of the National Curriculum of England. Research on systems thinking has…

Both graph comprehension and data analysis and interpretation are influenced by one's prior knowledge and experiences. To understand how one's prior knowledge and experiences interact with their analysis of a graph, we conducted think-aloud interviews with general chemistry students as they interpreted a graph to determine optimal conditions for…

We present an integrative mixed-methods systematic review of research on laboratory work in secondary-school science education from 1996 to 2019. The aim of the study is to identify important aspects of how to successfully make use of laboratory work as a science-teaching strategy in secondary schools. By engaging teachers, our study uses a…
