The underrepresentation of girls and students of color in STEM fields, particularly in science, is an ongoing issue that is very well documented. There is a limited amount of research that provides insight on experiences of girls, especially girls of color, who have been exposed to authentic science experiences. This article interrogates the…

Curricular reform efforts depend on our ability to determine how courses are taught and how instructional practices affect student outcomes. In this study, we developed a 30-question survey on inquiry-based learning and assessment in undergraduate laboratory courses that was administered to 878 students in 54 courses (41 introductory level and 13…

This study reports the use of data mining tools in order to examine the influence of the methodology used in chemistry lab classes, on the weight attributed by the students to the lab work on learning and own motivation. The answer frequency analysis was unable to discriminate the opinions expressed by the respondents according to the type of the…

Understanding and trouble-shooting microscopic processes involved in laboratory tests are often challenging for students in science education because of the inability to visualize the different steps and the various errors that may influence test outcome. The effectiveness of gamification or the use of game design elements and game-mechanics were…

A high quality science education in primary and secondary schools contributes to developing scientific literacy and would be expected to predispose students to study the enabling sciences at university. The major purpose of this study was to assess the practice and problems in science laboratory activities in the secondary school of Wolaita Zone,…

Teaching ecosystem services provides an ideal opportunity to use inquiry-based learning to help students make connections between ecological, geological, and social systems. The idea of ecosystem services, or the benefits nature provides to society, has emerged as a key concept in a host of environmental fields and is just beginning to gain…

Problem-based learning methods support student learning of content as well as scientific skills. In the course of problem-based learning, students seek outside information related to the problem, and therefore, information literacy skills are practiced when problem-based learning is used. This work describes a mixed-methods approach to investigate…

We present a multiweek laboratory exercise that exposes students to the fundamental techniques of bacterial expression and protein purification through the preparation of sperm whale myoglobin. Myoglobin, a robust oxygen-binding protein, contains a single heme that gives the protein a reddish color, making it an ideal subject for the teaching…

Mobile devices have become a popular form of education technology, but little attention has been paid to the use of their sensors for data collection and analysis. This article describes some of the benefits of using mobile devices this way and presents five challenges to help students overcome common misconceptions about force and motion. The…

This paper presents a new photovoltaic (PV) power systems laboratory module that was developed to experimentally reinforce students' understanding of design principles, operation, and control of photovoltaic power conversion systems. The laboratory module is project-based and is designed to support a renewable energy course. By using MATLAB…

The advances in communication networks and web technologies, in conjunction with the improved connectivity of test and measurement devices make it possible to implement e-learning applications that encompass the whole learning process. In the field of electrical engineering, automation or mechatronics, it means not only lectures, tutorials, demos…

Learning about scientific inquiry (SI) is an important aspect of scientific literacy and there is a solid international consensus of what should be learned about it. Learning about SI comprises both the doing of science (process) and knowledge about the nature of scientific inquiry (NOSI). German reform documents promote inquiry generally but do…

Thanks to their unique physicochemical properties (e.g., surface plasmon resonance), noble metal nanoparticles are at the cornerstone of nanotechnology. Silver triangular nanoprisms are presented here as an ideal playground to introduce students to nanochemistry concepts such as the formation of shape-controlled nanostructures. Not only a reliable…

This communication is a collection of additions and modifications to two previously published classic inorganic synthesis laboratory experiments. The experimental protocol for the synthesis and isolation of enantiomerically enriched ?- (or ?-)Co(en)[subscript 3]I[subscript 3] has been modified to increase reproducibility, yield, and enantiomeric…

Here we present the development of a 13 week project-oriented biochemistry laboratory designed to introduce students to foundational biochemical techniques and then enable students to perform original research projects once they have mastered these techniques. In particular, we describe a semester-long laboratory that focuses on a biomedically…
