Unizor is an open source mathematics and physics Web site that seeks to promote intellectual strength, creativity and analytical abilities. Unizor’s founder, Zor Shekhtman, does this through a series of lectures on mathematics and physics designed to help high school students exercise the mind just as one would exercise his or her body in a gymnasium. The abilities strengthened by using Unizor can readily be applied to real life. Another great strength of Unizor is that parents and other responsible adults are placed in charge of their students’ education.
So, how does Unizor do this? A parent/supervisor goes to Unizor’s Web site and creates an account for him or herself. The parent/supervisor then has two roles. The first is to enroll his or her students into instructional programs. The second is to manage the learners’ progression through the programs. Each student has an account created by the parent/supervisor which makes this possible. From here, students’ progress can be monitored, including exam scores, and they can be passed on to the next level within the course.
How does Unizor work? Each topic is presented by Zor Shekhtman as a video lecture. Far from being dry, Zor conveys his enthusiasm for the curriculum through his instruction, which makes the lectures very engaging. Zor also utilizes visual aids and examples to enhance the learning experience. The educational experience is further augmented by the use of other media and materials. Furthermore, teachers are not left out. To quote from the Unizor home page, “The function of a Unizor teacher is to provide quality educational materials. Control over educational process is not a function of a Unizor teacher, this is supposed to be provided by parents/supervisors.” Teachers can modify both instructional content and exams as well.
Unizor has a very different approach to mathematics education than the more prevalent principles utilized by many schools. These principles have an emphasis on formulas and procedures and the memorization of these. The problem with this is that students, not finding immediate real-world application for this information, will soon forget it once the assessment is passed. Unizor focuses on a logical and analytical approach to mathematics education, encouraging problem-solving, proving theorems, axiomatic foundation and rigorousness of educational material. This approach is conducive to the development of students’ minds, something that will be of value in any occupation.
Unizor is ideal for learners who have been identified as gifted and talented. The opportunities for academic and intellectual growth abound here. Be aware, that Unizor is a work in progress. However, there are more than 400 lectures available with more to come. You should also know that the physics component is still predominantly under development. So take control of your student’s learning and create a supervisor account on Unizor’s Web site today.
One of the great benefits of mailing lists is that you have the opportunity to learn about new things. In this case, the new thing that I have learned about via the schoolforge-discuss mailing list is FisicicaLab, an open source educational application developed to solve physics problems. FisicaLab handles all of the mathematics related to physics, giving the user the ability to focus purely on physics. So, without further adieu, let’s take a closer look at this thought-provoking piece of software.
The graphical interface is similar to that of GIMP, incorporating multiple windows. Unlike GIMP, FisicaLab utilizes only two windows initially. The main window is called the Chalkboard and the other window is entitled Modules and Elements. The Modules and Elements tool enables users to add items to the Chalkboard and to modify those items. Buttons at the top of the Modules and Elements window allow users to toggle between different types of elements. (See the screenshot for a typical session). Additional windows open as needed.
FisicaLab allows users to manipulate virtual objects such a blocks, pulleys and forces. These can be handled and allowed to interact in a variety of ways, including, but not limited to, relative motion, collision and explosion. Other factors that can be adjusted include friction and force, among others. FisicaLab gets a high level of expandability via additional modules which users can install. These modules include, but are not limited to, kinematics of particles, dynamics of particles and calorimetry, ideal gas and expansion.
This brief article is written merely to inform and cannot do this wonderful application justice. If you teach physics, FisicaLab is designed with both instruction and learning in mind.
FisicaLab is available for Linux, Microsoft Windows and Apple MacOS.

I’ve recently come across a piece of open source technology that will not only take the struggle out of getting your kids to do schoolwork at home, but will also put them in control of this work while helping them to self-monitor and develop independence at the same time. AutoTeach will do all of these things. So, what is AutoTeach and how can it do all of this?
With AutoTeach Parent Tool, students earn credits which can be used to “purchase” time on the Internet. There are three components that make this happen. the first is the Credit Meter. The student logs onto this via his or her wi-fi device (tablet, game system, etc.). While this is running, the student can access the Internet. The next component is a Raspberry Pi. For those unfamiliar with Raspberry Pi, they are open source palm-sized computers consisting of a motherboard with a CPU and RAM, as well as audio, video, SD card (used as hard drive), USB and LAN ports. In short, they are fully functioning computers. The Raspberry Pi serves as router, Credit Meter and firewall. By default, the firewall only allows the students to access the third component of AutoTeach, the Credit Reader Web site.
The activities are just as engaging as they are educational. By completing activities to a predefined skill level, students can earn credits toward free Internet time. You may actually find your kids begging to do schoolwork. A really neat feature of AutoTeach is that credits can be awarded manually. This means that you could use it as a reward for completing chores or other activities that you would like to encourage. In terms of personal growth, students will have greater control over their learning and a greater enjoyment of it. Through monitoring their own progress and working independently, young people will develop a sense of independence as well as one of self-reliance.
Arguably one of AutoTeach’s greatest strengths is its capacity for growth. Developers will be constantly creating new plugins. There is also a development suite available, AutoTeach’s Development Sandbox, which will allow developers to create plugins on their own. The result is that potential for more plugins is limitless.
As you can see, I am very enthusiastic about this technology. So how do you acquire AutoTeach? It is available as a subscription. To learn more, check out some of the resources below to which I’ve provided links.

I want to look at a fun application entitled LinCity-NG. As the name would imply, it is an open source clone of Electronic Artis’ (EA) SimCity. LinCity-NG has evolved quite a bit since my first encounter with it ten years ago. It has an aesthetically appealing interface and is highly customizable in terms of features and game play.
LinCity-NG is also a wonderful way for students to learn about both economics and ecology. My reasoning for this is that this game requires users to build a civilization. In order for a civilization to grow it must first survive and then expand. Surviving means that you must have a successful economy with employment, resources and trade. These things fluctuate during the game and to succeed, you must be able to compensate for them. In terms of ecology, as you expand, you will encounter various types of terrain, such as wetlands, that you must work around as removing them is very expensive. You must also be aware that civilizations generate pollutants. These pollutants must be dealt with responsibly in order to avoid repercussions. Keeping these factors in mind, let’s take a closer look at LinCity-NG.
When initially launched, LinCity-NG presents the user with a straightforward interface. The screenshot at left displays the main menu. Clicking the New option opens a menu allowing users to select a scenario. Available options include Beach, good times and bad times, among others. Personally, I like to start with an empty board and when I create my LinCity-NG academic unit (forthcoming), this will be required so that all students start at the same level in the game. If you’re experimenting with LinCity-NG, by all means try different scenarios. The titles are self-explanatory.
Once your game starts, you will be presented with a map of the terrain upon which a civilization must be built. There is a panel on the upper left-hand side of the screen that provides access to available actions and structures. In the lower left corner is what looks like the control buttons on a DVD player. These allow users to accelerate and pause the simulation or to run it at normal speed. Users can also access the main menu from here. In the lower right-hand corner, is a panel offering a map, some buttons below it and several tabs. Both tabs and buttons allow you to view various information about your civilization, such as economic standing and resource availability, among other things. The map is laid out in a rhomboid shape. Check out the screenshot at right for an idea of the initial layout.
In the beginning, users can create only the bare minimum in terms of structures for their civilization. As your civilization grows, more options become available. This is what would make LinCity-NG an ideal platform for learning. All learners start at the same level. Each could be provided with a rubric identifying what their society must have in terms of services and industry at specified points in game time. For example, “By simulation year 60, your civilization should have Residences and Farms powered by Windmills.”
Looking at the panel in the upper-left corner, each button represents a category. The top button allows you to toggle between the Query tool (mouse pointer),the Bulldozer and Water. Clicking on anything with the Query tool will provide information about that item in the little map window in the lower-right corner. The next tool on the panel allows you to iniitally build Residential areas. You can choose from one of three options, each of which affects the population levels differently. The button below this could best be described as basic resources. These include at outset Market (where jobs are created and goods exchanged), Farm (for food) and Water well.
The next button opens a menu that could be best described as social services. Initially, Monument (something to give the citizens pride in their community) is the only option available, but others include School, Fire Department and Sport (like a basketball court). Transportation is the next category. The only option available is Track (like a trail) at first, but others such as Road and Port can quickly be unlocked. Power sources are next and none of these are available at start up time. Windmills however can be readily earned to provide power to Residences and Farms, as I indicated above.
Resource sources are next. The options available at the beginning include Commune (a place where such goods as coal and steel are produced), Ore mine and Rubbish tip (landfill). Other choices that become available are Coal mine and Recycle (recycling center). Industries make up the final menu. Pottery is the only option available at outset (like all industries in the game, Pottery converts resources into goods). As the game progresses, users have access to Blacksmith, Mill, Light Industry and Heavy Industry. If you haven’t got all of that committed to memory, don’t worry. One of LinCity-NG’s greatest strengths is its integrated help. Just right-click on any of these options for more information about them.
I could write more on this stimulating application, but I leave it to you to explore LinCity-NG for yourself. Your students will be enrapt. There is one more academic aspect of LinCity-NG that I neglected to mention and that is creativity. Though you can use it to teach students about economics and ecology, one fun aspect for the educator is the opportunity to observe the worlds that students will create and how they vary. Student creativity is often one of the greatest rewards that educators can enjoy.

A person who reviewed Enertgize Education through Open Source felt that the book should have contained lesson plans with open source technology integrated into them. This has inspired me to do just that. Download the compressed file by clicking on the link below. Uncompress or unzip the file and you’ll have a folder containing a lesson plan and packet for a project designed to teach 8th-grade students how to use the periodic table of the elements. All you need to do is download and install Kalzium (Linux) or QPerdiodicTable (Microsoft Windows), both pf which are open source interactive periodic tables of the elements, onto students’ laptops and you’re ready to go.

OpenRocket is an application for virtually building and launching model rockets. This software was developed by Sampo Niskanen, who was a student at the Helsinki University of Technology when he developed OpenRocket as the focus of his graduate studies on open source software. OpenRocket is fun and easy to use. The online guide, Getting Started with OpenRocket. advises basing your rocket designs on existing products, so I chose to virtually create and launch an Estes Hi-Flier (kit number 2178) as shown in the image below.
OpenRocket launches with a pop-up window asking the user to provide rudimentary information about the rocket he or she plans to design (design name, designer and a field for comments). If desired, this window can be readily closed so that the user can begin working with the application.
The OpenRocket interface is very straightforward. A simple menu bar is at the top of the window, allowing users to perform common tasks (Open, Save, Undo, etc.). Below this are two tabs, Rocket design and Flight simulation. The Rocket design tab employs a kind of switchboard interface that allows users to select which model rocket components they would like to add to their build. The only three options available at start up are Nose cone, Body tube and Transition (a coupler that is tapered at one end). To the left of this switchboard is a window displaying a text-based tree-structure outline of your rocket. The lower half of the screen is the canvas upon which your design appears. The default is Side view, but users can toggle between this are Rear view. This canvas is flanked on top and to the left by rulers measuring centimeters. At the top of the OpenRocket window is a simple menu.
When a new component is added to your rocket, the Component configuration window opens providing information about the component’s shape, composition and mass, as well as offering options to modify the component. Additional tabs are available for configuring such categories as mass override, figure (illustration) style and a field for notes about the model. This feature can also be accessed by clicking on a component and choosing Edit from the switchboard menu just to the right of the outline window. Components in the outline area can be expanded to reveal sub-components or collapsed to hide them. Components can also be moved here by clicking on a component and dragging it to a desired location in the tree-structure. Furthermore, components can be modified using the switchboard immediately to the right of this window. Two really neat features included under the Analyze menu include Component analysis and Rocket optimization. These allow you to tweak your rocket’s performance.
Once you’ve added an engine, the fun begins, as the guide Getting Started with OpenRocket states, as you’re ready to enter into the simulation portion of the application. OpenRocket is well integrated with the model rocket industry in regards to measurements and sizes of various components. For example, when you are ready to select a motor, if you have properly configured your engine mount, only motors that will fit the engine mount will be listed. Once you have selected your engine (or engines), we’re ready to run a simulation. Click on the Flight simulations tab. The Flight simulations window has five buttons at the top of the screen allowing users to create, run and modify simulations. Below this is a pane in which are listed user-created simulations. Below this is the canvas showing the user’s rocket.
Clicking on New simulation opens the Edit simulation window. Under the Launch conditions tab, you can customize the simulation in terms of engine configuration, wind speed, atmospheric conditions and other launch conditions. When the launch is configured as desired, click the Run simulation button. A window with simulation information will flash on the screen. Click on the Plot/export button and this will open the Edit Simulation window. In this window, users can adjust various criteria relating to the simulation, such as launch conditions, simulation options and what types of data will be plotted. Once this information has been set, simply click the Plot flight button in the lower right corner and a window presenting a graphic representation of the rocket’s flight will open. What’s really fun is to tweak various rocket components and launch conditions to see how they affect a rocket’s trajectory.
So, what are the benefits to using OpenRocket? It provides a wonderful opportunity to build and test model rockets prior to launch. What this means to model rocket enthusiasts is that they will have a better opportunity to determine their rockets’ trajectories and, therefore, have a better chance at recovery. Plus, it’s a fun way to experiment with model rockets. Isn’t that really what it’s all about?
OpenRocket is available for Linux, Apple MacOS, Microsoft Windows and Android.

I am currently working on a review of an open source software item that model rocketry people will just love. OpenRocket is an application that allows users to create model rockets. More than just a canvas, OpenRocket allows users to simulate flights, analyze rocket performance and to optimize the design according to the results. Watch this space for more info.
We’ve all seen the ads for Lumosity, the Web-based service that boasts games that “train your bran”. You also have to pay to use Lumosity, something the ads don’t tell you. Well, I want to introduce you to a free and open source application that does the same thing and touches on exactly the same areas that Lumosity claims to address, but without the cost and fanfare. The application is gbrainy and we’re going to examine its components so you can see how it can help you train your brain.
First of all, you may wonder what are the components of gbrainy? gbrainy consists of four components: Logic puzzles which are designed to challenge your reasoning and thinking skills; Mental calculations, which measure your ability to mentally solve arithmetical calculations; Memory trainers are designed to test and improve your short-term memory; Verbal analogies assess your verbal aptitude.
Logic puzzles presents the user with a scenario and a question. Answers to questions can be both selected response and constructed response. The user can respond either by using the mouse, the keyboard or either one, depending upon the type of question. The puzzles measure users’ attention to detail as well as reasoning skills. So how do gbrainy’s Logic puzzles compare with Lumosity? Among the skills that Lumosity claims to promote are attention, speed of processing and flexibility. These games certainly help to cultivate these skills.
Mental calculations displays a mathematical equation to be solved by the user. The operations include common arithmetic operations, algebraic expressions, finding averages and working with decimals and fractions. The goal here is to determine the user’s ability to perform mental equations. gbrainy provides all of the data necessary to solve the problems. You need to provide the answers via keyboard or mouse. How does Mental calculations compare with Lumosty? They help to hone your speed of processing and problem-solving skills, just as Lumosity claims to do.
Memory trainers provides the user with objects to observe for a set period of time, then asks a question pertaining to what has been observed. These objects can be words, numbers or shapes and the amount of time to observe them is fixed. Input is given solely through the keyboard. For example,take a look at the Memory trainers screenshot to the right. After observing the numbers provided for the time allowed, gbrainy switched to a screen asking me how many odd numbers were listed on the previous screen. I actually found Memory trainers to be the most challenging of gbrainy’s puzzles due to the time factor. In comparison with Lumosity, Memory trainers matches it readily in terms of improving users’ short-term memory and their capacity to pay attention to details.
Verbal analogies assess and improve your vocabulary. The puzzles are all selected response. The user may be asked to choose the best definition for the word given from a list. Alternatively, the user may be asked to select a word that will best complete a given analogy. Additionally, gbrainy provides alternate answers that would have also been acceptable in addition to the answer provided by the user. This is a great opportunity to build your repertoire of synonyms. In terms of Lunosity’s goals, Verbal analogies strengthens both your long-term memory and your processing speed. The Verbal analogies screen is shown at left.
In closing, I just want to add that I did not write this to condemn Lumosity. I wrote this article to simply inform people that a free alternative is available. For more information, visit gbrainy’s Web site. gbrainy can also be played on the Web here.

Today I want to focus on the KDE Education Project or KDE-Edu. As you may know, KDE (K Desktop Environment) is an open source graphical interface for UNIX-based operating systems like Linux. KDE-Edu is a project started by the people at KDE with the intention of developing educational open source software for all ages, both learners and teachers.
The software that they produce addresses language arts, mathematics, science and social studies as well as other areas of learning, such as computer programming and occupational therapy. Language arts appplications range from KHangman, a variation of the popular word game to KWordQuiz, a vovabulary builder, to Parley, a powerful vocabulary assessment tool. Mathematics applications range from KBruch, a tool for quizzing users about fractions and facotrizations to applications addressing more advanced topics, such as KAlgebra for graphing algebraic expressions and Kig, an interactive geometry tool.
In terms of science software, KDE Edu has some interesting offerings. These include, but are not limited to, an interactive periodic table of the elements, Kalzium, a virtual planetarium for your computer desktop, KStars and Step, an application that allows users to create virtual two-dinmensional physical science experiments. If you’re looking for social studies applications, check out Marble, a virtual globe that allows users to view Earth from various perspectives including geographical, historical and climate or KGeography, an application that quizzes users on their geographical knowledge including locations, capitol cities and flags.
Other applications include KTurtle, a program teaching beginning computer programming, KTouch, a typing/keyboarding tutor and KLettres, a tool for teaching younger students how to write their letters.
I cannot do KDE-Edu justice in this short space. There are more applications available than I have discuessed here. I urge you to check them out. They’re open source, free and will soon (as of this writing) be available for Microsoft Windows.
