This paper describes the development of a light polarization experimental apparatus for a remote laboratory. The apparatus had been developed by controlling the analyzer rotation using a stepper motor controlled via the Arduino. Device control and data acquisition applications were developed with LabVIEW which provides remote control panel…

This study has proposed a simple method to show the convective heat transfer. The object in this study is an air conditioner (AC) as a simple case of convection. In addition, AC is also easy to find in the class because most classrooms in Indonesia installed AC. Usually, a visualization needs special software (i.e. MatLab or others) and good…

Teaching materials used in distance education are generally obtained from the internet as ready-made by teachers. Materials such as simulation, animation and presentation are usually limited to the frame drawn by the creator and do not allow changes outside this limit. In addition, many of these types of materials do not have a feedback mechanism.…

This work combines laboratory quantitative analysis of colored solutions and common devices for digital imaging (digital or web cameras or mobile phones, i.e., smartphones). ColorX software, specially designed for this study, was used for data collection and analysis in order to calculate concentrations of colored solutions from measured RGB…

One challenge of teaching chemical analysis is the proliferation of sophisticated, but often impenetrable, instrumentation in the modern laboratory. Complex instruments, and the software that runs them, distance students from the physical and chemical processes that generate the analytical signal. A solution to this challenge is the introduction…

Solar system is an abstract phenomenon that needs to understand by junior high school students. The phenomenon cannot be observed directly in the classroom. In this research, the role-play model is first proposed to provide analogical phenomenon combined by Stellarium as an astrophysical virtual laboratory to give better visualization of Solar…

We present a simple and accurate experiment to obtain the speed of sound in air using a conventional speaker and a microphone connected to a computer. A free open source digital audio editor and recording computer software application allows determination of the time-of-flight of the wave for different distances, from which the speed of sound is…

This exercise demonstrates the principle of parsimony in constructing cladograms. Although it is designed using mammalian cranial characters, the activity could be adapted for characters from any group of organisms. Students score categorical traits on skulls and record the data in a spreadsheet. Using the Mesquite software package, students…

It is well known that laboratory applications are of significant importance in chemistry education. However, laboratory applications have generally been neglected in recent educational environments for a variety of reasons. In order to address this gap, this study examined the effect of a virtual chemistry laboratory (VCL) on student achievement…

This article describes LabSkills, a revolutionary teaching tool to improve practical science in schools. LabSkills offers the chance to help improve the exposure that the average Key Stage 5 (age 16-19) student has to practical work. This is a huge area for development being highlighted by universities who are seeing a worryingly growing trend in…

A number of tools and techniques have been developed to assist students with blindness and visual impairment who are studying in secondary and post-secondary science laboratories. Commercial electronic probes and their associated software packages allow real-time viewing and collection of data using a personal computer; however, until now, these…

This paper presents the development of a 3-D virtual environment in Second Life for the delivery of standards-based science content for middle school students in the rural Appalachian region of Southeast Ohio. A mixed method approach in which quantitative results of improved student learning and qualitative observations of implementation within…

Online learning is growing rapidly across the United States within all levels of education, as more and more students and educators become familiar with the benefits of learning unconstrained by time and place. Across most states and all grade levels, students are finding increased opportunity, flexibility, and convenience through online learning.…
