Plastic embryological models lack the excitement of seeing real, live embryos. Chick embryos are often used to demonstrate embryological development and blood circulation to students but this necessitates the death of the organism. "Kryptolebias marmoratus" embryos are large and can be viewed by means of a light microscope without need…

In this technology report, a tool is provided for teaching reciprocal space to undergraduates in physical chemistry and materials science courses. Reciprocal space plays a vital role in understanding a material's electronic structure and physical properties. Here, we provide an example based on previous work in the "Journal of Chemical…

Safety education is absent in the chemistry curriculum. This commentary discusses the consequences of the missing safety education for graduates and institutions that hire them. It suggests and discusses the application of the theory of Normalization of Deviance to explain why safety education is missing. It suggests ways to fix the shortcoming by…

Research has focused on identifying and overcoming determinants that impede widespread adoption of instructional interventions, with little empirical examination of postsecondary educators' perceptions about these interventions. We explored postsecondary biology educators' sensemaking of education improvement interventions targeting undergraduate…

This article is about the development of an Internet-based remotely-controlled physical experiment, this is a part of the Remotely Controlled Laboratory at the University of Applied Sciences of Cologne known as TH Köln. The main experimental set-up is based on Pohl's Torsion Pendulum which was enhanced by a PXI measurement system and a webcam. In…

Undergraduate research opportunities have expanded from elite universities in the United States to universities and institutions of all ranks and sizes. Research studies have shown positive outcomes in regards to the research experience for undergraduates (REU), such as enhanced research skills and competencies. However, with the widespread…

Distance education programs in higher education are gaining popularity mostly due to the flexibility of the formative programs to fit all the requirements that brick-and-mortar educational institutions are not able to provide to students. However, quite often these distance programs report feelings of isolation, lack of self-direction and…

Background: Students' well preparedness for laboratory sessions is of importance for a number of reasons including them being able to engage in and learn from the session and in acquiring the necessary laboratory skills needed for the scientific community and for possible further work in industry. To enhance the preparedness of the students an…

This study aims to examine students' reasoning based on the model in each laboratory work style and find the effect on scientific attitude and student activity. This study uses a quantitative approach with the experimental method. The study was conducted in three classes with different lab work styles. Arduino and sensors were used as a…

Science faculty are being asked to create active learning experiences that engage students in core concepts and science practices. This article describes an approach to developing active learning lessons from authentic science research projects using the 5E lesson format. Included is a description of the 5Es and a template for creating a 5E…

The use of active learning techniques in engineering classrooms has been limited despite substantial evidence supporting their efficacy in helping students construct problem-solving expertise. A blended classroom, which combines online and in-class learning, was employed in a Chemical Engineering Computation class to address instructional…

This paper presents a case study on the teaching and learning of fluid mechanics at the University of Western Sydney (UWS), Australia, by applying a blended learning approach (BLA). In the adopted BLA, various flexible learning materials have been made available to the students such as online recorded lectures, online recorded tutorials, hand…

An experiment for an undergraduate organic chemistry class based on the application of an ionic liquid as solvent and catalyst of an organic reaction is reported. The whole experiment requires three 3-h lab sessions. First, students prepare the ionic liquid dimethylimidazolium methylsulfate, which is then used as a recyclable catalyst/reaction…

A laboratory experiment was developed to investigate the rheological properties of a green calcium-cross-linked alginate gel as an alternative to the traditional borax-cross-linked poly(vinyl alcohol) gel. As borax is suspected of damaging fertility and the unborn child, a safe, green alternative is necessary. The rheological properties of a…

Biochemistry subject had problem in learning and teaching, especially in laboratory work. We explored laboratory learning implementation in Biochemistry subject. Participants of this research were 195 students who took biochemistry subject and 4 lecturers of biochemistry in three universities in Indonesia. We obtained data using questionnaires and…
