Teacher education needs to combine training in content knowledge, pedagogical knowledge, and pedagogical content knowledge (PCK). One important part of PCK in science education is knowledge about school science practical work to promote learning by scientific inquiry and about the nature of science. In Germany, practical seminars and lab sessions…

In recent years, with the more powerful functions of smartphones, the use of sensors integrated by mobile phones as an auxiliary tool for physical experiment teaching has become more popular. Combined with the related mobile phone apps, people easily can develop and expand the physical experiment contents of mechanics, optics, acoustic phenomena,…

Currently, the physics disciplines are represented by a significantly larger number of professional males, compared to females. Although the problem of underrepresentation of female physicists has several causes, one likely reason is the lower interest that female school students have in physics activities. Several instructional solutions have…

This study investigated the effects of providing domain information in an early stage of an inquiry process, together with an aligned hypothesis scratchpad, on inquiry learning, and hypothesis generation in particular. Participants were provided with basic domain information that was adapted to their prior knowledge (experimental condition) or…

In an era where technology is being used more and more in daily life, the potential and effective use of technology is becoming increasingly vital in education. Engineering education necessitates the use of technology to assist students in understanding abstract concepts and principles. Augmented reality (AR) is a technology that can be used to…

A pilot study, funded by the Gatsby Charitable Foundation, supported 10 secondary schools across England to plan and deliver open-ended investigative practical work within science curriculum time. This enabled all students to experience the benefits of investigative work, rather than just those attending extracurricular STEM enrichment activities.…

Dissection is a unique multisensory educational experience and is essential to learning the anatomical construction of the human and animal bodies. This study aims to introduce a specialized design for the assessment of dissection and to discuss the assessment's attributes. The design was a product of the "assessment drives learning"…

The natural sciences, by their very nature, are based on the exploration of the physical world, and digital mobile devices are considered appropriate to support this exploration (Suárez et al., 2018) since they offer the tools that make this investigation more accessible but also ubiquitous (Crompton et al., 2017). Inquiry-based learning is a…

In this work, an alternative Experimental Didactic Kit for teaching resistors, capacitors and "RC" timing circuits was developed, using the Arduino platform technology, which is composed of a microcontroller and peripherals, due to the easy access to available teaching materials, enabling the reproduction of the prototype in the future…

Science and technology education necessitates teaching and learning experiments involving electronic circuit construction and measurements using experimental equipment. In this study, a novel cross reality system for learning physical circuit construction and performing virtual experiments using virtual experimental equipment with mid-air haptics…

The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

Undergraduate-level laboratory experiments that involve the synthesis of nanomaterials with well-defined/controlled shapes are very attractive under the umbrella of nanotechnology education. Herein we describe a low-cost and facile experiment for the synthesis of Cu(OH)[subscript 2] and CuO nanowires comprising three main parts: (i) synthesis of…

This lab experiment describes a complete method to fabricate an enzymatic glucose electroanalytical biosensor by students. Using miniaturized and disposable screen-printed electrodes (SPEs), students learn how to use them as transducers and understand the importance SPEs have acquired in sensor development during the last years. Students can also…

The principles of process-oriented guided inquiry learning (POGIL) are applied to a binary solid-liquid mixtures experiment. Over the course of two learning cycles, students predict, measure, and model the phase diagram of a mixture of fatty acids. The enthalpy of fusion of each fatty acid is determined from the results. This guided inquiry…

The synthesis of epoxidized soybean oil (ESO) provides students a vantage point on the application of green chemistry principles in a series of experiments. Qualitative tests review the reactions of alkenes, whereas spectroscopic analyses provide insight in monitoring functional group transformations.
