In 2012, engineering was adopted as a content area in K-12 science education. Yet few science teachers have engineering content or pedagogical content knowledge. Teachers learn how to teach engineering through professional development experiences, for which Darling-Hammond et al. (2017) outline seven characteristics of effectiveness. This…

The rapid transition to remote teaching in the spring of 2020 posed particular challenges for laboratory courses, which often involve students working hands-on with equipment in collaborative environments. Replicating in-person experiments was especially challenging for advanced lab courses that utilize specialized apparatus, which could not be…

While the use of experiments is important for developing students' scientific knowledge and skills, challenges may arise when teachers and students are conducting experiments in class, such as non-reusable experimental resources, safety issues and difficulties simulating some specific effects. Augmented reality (AR) technology affords an…

The purpose of this study was to investigate the development of pre-service chemistry teachers' (PCTs') argumentation skills in a laboratory course throughout a semester. A case study design was utilised. A total of six PCTs participated in the study. To investigate the development of PCTs' argumentation skills, the laboratory reports that were in…

COVID-19 has changed about every aspect of life including how we teach in higher education. Laboratory experiments vital for learning hands-on techniques are limited due to social distancing requirements and increased numbers of distance-learning students. The solution to loss of hands-on activities has been to compensate with virtual laboratory…

A digital lecture with motivating experiments--how can this be done in practice? This question shall be answered in the context of a case report from the field of material science. A digital experimental lecture as a substitute for a lecture with student experiments was evaluated by students to provide information on whether an adequate substitute…

This study aimed to develop, introduce, and conduct an inquiry-driven creative drama activity. The activity, for elementary students, related to the transmission of light and full shadow. In the activity, which consisted of a warm-up, dramatization, and evaluation stages, two inquiry-based experiments were added to the dramatization stage. Thus,…

Single slit diffraction is part of many high-school physics curricula throughout the world. In this study, we aimed to investigate whether high-school physics teachers from Bosnia and Herzegovina, Serbia and North Macedonia are adequately prepared to discuss with their students about various aspects of the single slit diffraction pattern,…

Contribution: A 3-D interactive learning environment, from which students of different levels in the control engineering background can benefit regarding classroom demonstration and online experimentation, is present. The findings support that students can benefit from the application of the online laboratory. Background: Control system design is…

In this research, the effect of experimental applications by using robotics technology in Science and Technology course the "Force and Motion" unit on the level of scientific creativity and scientific attitude of students was investigated. This research was designed according to the quasi-experimental method pre-test post-test design…

The introduction of the computer into the educational process is a fact. The educational use of new technologies creates a new, more appealing and enjoyable learning environment. The introduction of new technologies into school differentiates the role of the professor by giving him/her a guiding character in a process of experiential approach to…

The COVID-19 pandemic necessitated the move to online teaching and assessment. This has created challenges in teaching laboratory skills and producing assessments that are robust and fair. Our solution was to use bespoke laboratory videos to provide laboratory training and to generate unique data sets for each student in coursework and exams. For…

This paper describes an inquiry-based integrated laboratory project for green synthesis, characterization, and applications of silver and gold nanoparticles. In this project, students were able to choose their choice of plant extract as reducing and stabilizing agents, and the students also designed their own experiments. This course gave the…

Virtual manipulatives running on tablets have been demonstrated to improve students' conceptual understanding in previous studies. However, the differential effects on group interaction during face-to-face collaborative inquiry learning from the support of alternative technology affordances has received little attention. Technology affordances in…

This paper describes an experimental investigation of the skin depth effect for electromagnetic waves in salt water using a cell phone that is immersed to a critical depth where it no longer responds when called. We show that this critical depth is directly proportional to the theoretical skin depth for a range of salt concentrations.
