Probeware 'LabQuest' for Inquiry-Based Lab Activities

Ontario curriculum strongly emphasizes learning science by the inquiry-based framework, as inquiry is central to the teaching and learning of science. Inquiry-based learning is based on the constructivist approach as it encourages learners to learn inductively through concrete experiences and observation with the help of real-world exemplars (Colburn, 2004).

Collecting data through observations or measurements is a key element in science education. Often times, students use a wide range of instruments to collect, analyze and interpret data. For example, most widely used equipment are thermometers, pH paper, ammeters, voltmeters and hygrometers. The collected data is written down and then represented in tables/ graphs for further calculations, interpretations or to draw various conclusions. Until recently, this was done and still being done in many parts of the world manually. Today, however, another dimension of technology being used in science labs (besides Simulations) known as 'Probewares' has made it very easy to collect and present the data and support inquiry-based learning in the science laboratory.

Probeware also referred as Microcomputer-Based Labs (MBL) or Calculator Based Labs (CBL) is basically a tool that connects probes and sensors with a computer system running suitable software.  It helps to collect, display, and record or analyze data over a short period or very long period of time.(To learn more, please visit the website http://probesight.concord.org/ ).

Probeware eliminates tedious laboratory setups and helps to collect or record data that sometimes is difficult to collect with traditional laboratory instruments.  Thus, they reduce the mechanical aspects of data collection in an experiment that often impede student learning.  There is a large range of probeware applications being used in school science laboratories and scientific labs.  
One such probeware, I found worth having in high school Physics laboratory is LabQuest from ‘Vernier Software & Technology’. It is a standalone interface used to collect sensor data with its built-in graphing and analysis application. It also offers the latest version ‘LabQuest 2’ that has wireless capability and touch screen interface. Interestingly, Vernier also provides free on-line training webinars and videos to teachers.
Following video provides a good illustration of its functions.

Logo of Geometer's Sketchpad Today information and communication technology (ICT) have  provided a wide range of tools that significantly enriches math teachers’ instructional strategies and support students’ learning in mathematics. These ICT tools can be used both for whole-class instruction or to design programs that meet diverse needs of student by the teacher. Screenshot of Fathom Screenshot of Graphic Calculator Many useful ICT tools include multimedia resources, databases, and different websites that give access to large amounts of statistical data, and computer-assisted learning modules. Besides the software tools such as Geometer’s Sketchpad , Excel , Fathom , Graphmatica , Graphing Calculators , Winplot , SMART Notebook and Graphcalc.com etc. are great to supplement various mathematical topics effectively. Along with these come many applications such as databases, spreadsheets, computer algebra systems (CAS), word-processing software, math

Math Talk

Let us talk Math! I remember many years back when I was a student; there was very less emphasis on discussion in the class during the session. Best students would be those who were sitting silently and seems to be working seriously! There is no doubt in the fact that there are different learning styles. However, in changing times, there is more focus on activity-based courses where children learn to become confident problem solvers by engaging in meaningful talks and that could be in pairs, small groups or in whole groups. The National Council for Teachers of Mathematics (NCTM) Standards emphasizes the need for students to discuss their mathematical thinking as a way to increase understanding. There are many ways to engage students in purposeful math talk. Asking questions is one of the important ways by which they learn to reason mathematically. Some of the significant questions that could motivate and engage students to get involved in meaningful ‘Math Talk’ are; What do you th

Project-Based Learning

The article “Project-Based Learning Research Review” in edutopia is an excellent piece of knowledge that sums up the benefits and scope of the project-based learning. The article explores the vast body of research on the topic and in the series of five articles; it detail the definition of project-based learning, review the possible learning outcomes, give recommendations of evidence-based components for successful PBL and suggest the best practices across disciplines, to name a few. What is Project-Based Learning? The basic principle of project-based learning is an inquiry-based approach of teaching and learning. Teacher provides the students with a question or problem that could be driving, challenging or intriguing and that in turn encourage and guide their learning. Students are free to work in groups, pairs or individually to conduct research, collect or construct material and evidences. They, therefore, approach the problem in a systematic and guided way in order to create m
