The laboratory plays a crucial role in science education. However, teacher education for pre-service teachers' design performance in the laboratory is still challenging. This study paved the way for redesigning traditional laboratory teaching into a student-centered approach: inquiry-based design thinking (IBDT). To investigate the impact of the…

This study investigates the ability of future primary school teachers to design experiments when confronted with everyday life problems, particularly those involving complex phenomena or counterintuitive outcomes. Data were collected using a content analysis approach from the written assignments submitted during a Science Education university…

Common over-the-counter medicines can be an exciting entry point for introducing students to the interesting chemistries that they encounter in their daily lives. In this inquiry-based activity, students are tasked with using a list of given supplies and information about four medications (Aspirin, Tums, Pepto-Bismol, and Tylenol) to design three…

Purpose: Hands-on training in tissue engineering is often associated with specialized labs and expensive equipment, such as CO[subscript 2] incubators. To minimize the use of costly commercial incubators and provide a more vivid engineering experience in a biology lab, we present a hands-on project that introduces medium to large groups of…

Science, technology, engineering, and mathematics (STEM) project refers to experiments conducted to address problems, make improvements, or discover new things in those fields that can be tested using the scientific method. This paper describes a long-term STEM project in which pre-service science teachers (PSSTs) have a chance to discover new…

Enzymes, enzymatic kinetics, and enzyme inhibition are topics covered in undergraduate biochemistry textbooks, having perceptible relevance to everyday life. The experimental use of enzymes involved in basic physiologic processes may be of utmost pedagogic interest because they bring evidence on how a significant number of drugs are used to…

Background: Physics textbooks are a learning resource for students to acquire knowledge and information. The findings of previous studies on physics textbooks analysis have mostly focused on representations of gender, the nature of science, and scientific literacy. This study, therefore, extends the critical content analysis of physics textbooks…

In today's world shaped by technology and the natural sciences, knowledge and skills related to experimentation are crucial, especially given growing public debates about science-related topics. Despite a strong emphasis on experimentation in science curricula worldwide, learners still encounter diverse challenges when experimenting. This paper…

In this study, students' understanding of some important features of competitive elimination and substitution reactions of alcohols was examined based on their participation in a guided inquiry activity of two organic laboratory experiments: the dehydration of cyclohexanol and the conversion of tert-butyl alcohol into tert-butyl chloride. Students…

The main objective of this intervention study was to investigate the effect of three teaching approaches, namely the traditional teaching method (TTM), a teacher-based demonstration experiment (TBDE) and a student hands-on experiment (SHE), on students' academic performance. A total number of 324 senior five students studying chemistry as one of…

The purpose of this study was to investigate the frontier, science, and public engagement of educational science research. This paper conducted a systematic literature review of 101 educational science research articles published in "Nature" and "Science" in 1982-2021 based on the Web of Science database and analyzed the…

Scientific inquiry is an inquiry-based learning approach that emphasizes student investigation of research questions and the utilization of scientific methods to address those research questions. One such method is experimentation, which is viewed as an open-ended problem-solving process that is mostly perceived by students as a complex procedure.…

It has been shown that active learning strategies are effective in teaching complex STEM concepts. In this study, we developed and implemented a laboratory experiment for teaching the concepts of Boolean logic gates, molecular beacon probes, molecular computing, DNA logic gates, microRNA, and molecular diagnosis of hepatocellular carcinoma, which…

This paper presents an innovative teaching approach that integrates photoelectric technology with analytical chemistry instruction through inquiry-based learning (IBL), using cerium as a selected analyte. With the advancement of science and technology, a strong foundation of basic knowledge and methodologies is crucial in analytical chemistry…

This study investigates the effectiveness of using a REACT strategy instruction enriched with guided inquiry-based experiments to improve 7th-grade students' understanding of mixtures compared to conventional teacher-centered instruction. A convergent parallel mixed-method design was used, and 39 middle school students were divided into…
