Virtual experiments offer opportunities for students to engage in the scientific process and observe scientific phenomena. However, virtual experiments are not always effective for learning. The current study examined how two small manipulations might support better learning from virtual experiments and the extent to which this varied across…

Archimedes' principle has been and still is a complicated concept to understand by introductory students, especially as typically stated in physics textbooks. Take for example its statement by Bierman: "When a body is fully or partially submerged in a fluid, a buoyant force from the surrounding fluid acts on the body. The force is directed…

Retrieval practice is an evidence-based approach to teaching; here, we evaluate the use of PeerWise for embedding retrieval practice into summative assessment. PeerWise allows anonymous authoring, sharing, answering, rating, and feedback on peer-authored multiple choice questions. PeerWise was embedded as a summative assessment in a large…

3D holograms are an effective tool for visualization, and their utilization in chemistry teaching can be beneficial in improving learning outcomes. However, studies on students' opinions about holograms in chemistry teaching and learning are scarce. The research aimed to examine the views of chemistry students on the application of 3D holograms in…

Learner engagement is well-established as critical for learning online. Professional development for online instructors emphasizes techniques for engaging students, and learning technology products tout features intended to promote engagement (e.g., adaptive content, video, gamification). But the influence of particular instructor practices and of…

Students often perceive statistics as a difficult subject, and it is frequently named as one of the primary causes of high dropout rates in economics educations in Norway. In order to support the learning process in statistics courses, and in order to make the courses more flexible, the author experimented with the use of Padlet in two different…

We recorded the percentage of students voting on each option on every clicker question used in 19 introductory statistics classes. To identify the questions that provide the most useful feedback, we looked for those for which the percentage of students voting correctly varied the most from class to class, producing the largest standard deviations.…

Training in chemistry is essential for undergraduate medical students; however, at the National University of Colombia, basic chemistry courses are associated with high fail rates and low academic performance with regard to first semester students, especially in vulnerable special admission populations. A longitudinal study was carried out via…

This paper summarizes our experience of teaching undergraduate robotic courses in the past ten years. The objective is to introduce students to the fundamental knowledge in robotics. Lecture topics covered subjects in both Autonomous Mobile Robots and Robotic Manipulator. In the lab sessions, students work on physical robots to acquire basic…

A growing number of faculty in higher education are using technology applications in their teaching practices. However, a gap in the literature exists related to instructional technology integration in liberal arts courses. This gap also exists in theater education, where I have spent the last 20 years of my professional life. This self-study…

Microsoft PowerPoint was one of the Microsoft Office applications developed by Microsoft since 1990 and has been used widely for disseminating information and presenting reports. PowerPoints are normally produced in slides to be projected on the screen or whiteboard for the audience to see. However, the strengths of PowerPoint go beyond slide…

This article illustrates ways that dynamic software using some sophisticated techniques in Excel can be used to demonstrate fundamental ideas related to hypothesis testing to increase student understanding of the concepts and methods in elementary statistics courses. The article considers hypothesis tests for the population mean with large or…

The purpose of this randomized experimental study is to apply two socio-cognitive models to understand possible ways to improve students' learning outcomes in an online introductory chemistry learning environment. Specifically, the social presence theory suggested that students' sense of relatedness and learning motivation can be increased by a…

This study investigates the effectiveness of two statistical software packages, the commercial software, SPSS, and the free software, R Version 3.5.0, in teaching statistics, by comparing grades earned by students in an introductory statistics course. Students taught using R earned slightly higher grades overall than those in the SPSS class,…

In introductory physics classes, a laser pointer and a compact disc are all the items required to illustrate diffraction of light in a single dimension. If a two-dimensional diffraction pattern is desired, double axis diffraction grating material is available or a CCD sensor can be extracted from an unused electronics device. This article presents…
