The trebuchet has quickly become a favorite project for physics and engineering teachers seeking to provide students with a simple, but spectacular, hands-on design project that can be applied to the study of projectile motion, rotational motion, and the law of conservation of energy. While there have been free trebuchet simulators and range…

Financial analysts generally create static formulas for the computation of NPV. When they do so, however, it is not readily apparent how sensitive the value of NPV is to changes in multiple interdependent and interrelated variables. It is the aim of this paper to analyze this variability by employing a dynamic, visually graphic presentation using…

This study examines the effect of computer-assisted language learning on the vocabulary learning of Iranian EFL learners, in which 40 pre-intermediate and intermediate students enrolled at Iran Language Institute, Urmia, Iran were selected as participants. The participants were randomly assigned to two experimental groups and two control ones. The…

Science becomes engaging when students know that what they learn in the classroom relates to their own lives and communities. This article describes a project in which students use field exploration and online software to design virtual solutions to improve the hydrology of their school yard. The project is called Teaching Environmental…

In this paper, a Chinese character educational system based on Kinect is proposed for guiding beginners to learn the basics of Chinese characters in a more intuitive way. It extracts 19 common components, denoted as alphabets, from Chinese characters. Nineteen postures were designed according to the shapes of these alphabets. Instead of memorizing…

Use of advanced mass spectrometry techniques in the undergraduate setting has burgeoned in the past decade. However, relatively few undergraduate experiments examine the proteomics tools of protein digestion, peptide accurate mass determination, and database searching, also known as peptide mass fingerprinting. In this experiment, biochemistry…

In this article, the author discusses how graphical simulation models created using STELLA software can be used to present natural resource systems in an intuitive way in undergraduate natural resource economics classes based on his experiences at a leading research university, a state university, and a leading liberal arts college in the United…

The effects of courseware learning for children with learning difficulties have been studied over the years. Educational courseware is very common nowadays as a teaching tool for children's early education. However, most of the coursewares are designed for children with normal learning ability. Special children who face difficulty in the learning…

This paper evaluates the affordability of "Quipper" as an online platform for teaching and learning English as a foreign language (EFL). It focuses on the extent to which features available in "Quipper" may correspond to fundamental components of Computer-Assisted Language Learning (CALL) pedagogy, as suggested by Chapelle…

Gateway courses in English challenge students to strengthen skills in critical thinking, reading, grammar, and writing structure and strategies -- skills that also help build competency in comprehension and composition. They can also prove to be a particular challenge to many community college students. This case study examines the efforts at…

The binding constant and stoichiometry ratio for the formation of iron(II)-(1,10-phenanthroline) or iron(II)-o-phenanthroline complexes has been determined by a combination of a low-cost analytical method using a smartphone and a molecular modeling method as a laboratory experiment designed for analytical and physical chemistry courses. Intensity…

In this article the authors present the concept of Coding Literacy and describe the ways in which coding apps can support the development of Coding Literacy and disciplinary and digital literacy skills. Through detailed examples, we describe how coding apps can be integrated into literacy instruction to support learning of the Common Core English…

In this research article an analysis and evaluation of virtual learning spaces is carried out. To address this process, three (3) academic virtual platforms were selected, Moodle, Blackboard and Jimdo. The methodology used was of a descriptive type, applying the synchronous and asynchronous methods of virtual teaching established in each of the…

The conveyance of knowledge of the life cycles performed by fungi and plants with spores is a challenge for teaching in university education. The life cycles of fungi, in particular, can be very complex and difficult to understand. This paper presents the development and implementation of a German and English educational software program,…

Business education is undergoing paradigmatic changes, and business schools are feeling the brunt of these changes. This article proposes that "business as usual" is over for traditional business schools. Using Ohmae's 3Cs--customers, competitors, and company--as an analytical framework, I examine important changes from different vantage…
