The present invention relates to a distance learning device for providing laboratory instruction via two-way interaction with a student at a remote location and system for using same.
Distance education, or distance learning, is the education of students who are not physically present at a university or educational center. This type of educational situation is also referred to as distributed learning, e-learning, online learning, etc. The widespread use of computers and the Internet have made distance learning economical, as well as easier and faster. Currently, virtual schools and universities deliver full curricula online. The capacity of the Internet to support voice, video, text and immersion teaching methods made earlier distinct forms of telephone, videoconferencing, radio, television, and text based education somewhat redundant. However, many of the techniques developed and lessons learned with earlier media are used in Internet delivery.
The first fully online university was founded in 1994 as the Open University of Catalonia, headquartered in Barcelona, Spain. In 1999, Jones International University was launched by Glenn Jones, CEO and Bernard Luskin, Chancellor as the first fully online university accredited by a regional accrediting association in the US.
Between 2000 and 2008, enrollment in distance education courses increased rapidly in almost every country, both developed and developing. Many private, public, non-profit and for-profit institutions worldwide now offer distance education courses from the most basic instruction through to the highest levels of degree and doctoral programs. New York University, for example, offers online degrees in engineering and management-related fields through NYU Tandon Online. Levels of accreditation vary: widely respected universities such as Stanford University and Harvard now deliver online courses—but other online schools receive little outside oversight, and some are actually fraudulent, i.e., diploma mills. In the US, the Distance Education Accrediting Commission (DEAC) specializes in the accreditation of distance education institutions.
Distance education has a long history, but its popularity and use has grown exponentially as more advanced technology has become available. By 2008, online learning programs were available in the United States in 44 states at the K-12 level. Internet forums, online discussion group and online learning community can contribute to an efficacious distance education experience. Research shows that socialization plays an important role in some forms of distance education.
By 2011, a third of all U.S. students enrolled in postsecondary education had taken an accredited online course at a postsecondary institution. Even though growth rates are slowing, enrollment for online courses has been seen to increase with advances in technology. The majority of public and private colleges now offer full academic programs online. These include, but are not limited to, training programs in the mental health, occupational therapy, family therapy, art therapy, physical therapy, and rehabilitation counseling fields. Even engineering courses that require the manipulation and control of machines and robots that are technically more challenging to learn remotely are subject to distance learning through the internet.
Interactive Distance Learning (IDL) is a proven training method that uses interactive technologies to allow instructors and students to communicate from geographically dispersed locations. Instruction can be transmitted through a business television network, point-to-point videoconferencing networks, or over the Internet or intranets. IDL allows one instructor to transmit to and to train a potentially unlimited audience. Plus, it provides a means for immediately ascertaining audience comprehension and tracking overall training results. The classic IDL model is the transmission of training over these networks in an essentially broadcast-type manner, with feedback permitted back to the instructor.
However, one drawback with distance learning programs is how to effectively administer “hands on” lab activities in educational fields that require laboratory time in order to understand the subject matter. Students at remote sites are typically not able to train in a real-time environment using specialized, expensive apparatus as transporting the specialized, expensive equipment or apparatus to the remote site for real-time environment training is cost prohibitive.
What is needed in the art is a way of enabling distance learning between a student(s) and teacher that provides a way for the student(s) to conduct experiments, with the professor actively observing and providing guidance as needed. Further, the current disclosure seeks to improve student retention in online courses by revolutionizing the online course environment via improved interaction.

In one embodiment, the current disclosure is directed to a distance learning system for allowing a student or trainee and an instructor or professor to actively interact with one another to conduct lab environment type classes. For instance, in a preferred embodiment, a student or trainee could work with a professor or instructor to conduct a laboratory directed to building electronic circuits. The current disclosure is applicable to any laboratory educational events wherein an instructor would observe status, conditions, or procedure and interpret the status, conditions, or procedure so as to direct or redirect a student(s) to learn, comprehend or make corrections to a procedure to achieve objectives or obtain desired results. For example: a slight modification may occur so as to include sensors, transducers or instrumentation to be interfaced into a breadboard. Analog tap voltages would represent scaled values for physical variables such as temperature, pressure, flow, level, position, velocity, acceleration, analytical, etc.
Workstation 6 may be a multifunctional surface such as a breadboard for electronic laboratory operations. A breadboard In other embodiments, workstation 6 may contain chemical ingredients for chemistry laboratories, or may be a visual interface for students learning a language. In a further embodiment, workstation 6 may include portable laboratory equipment, such as a spectrophotometer, necessary labware, and reagents for different chemical parameters. For biological laboratories, workstation 6 might include a portable incubator and labware to test for parameters such as chlorine (free and total), coliform (total, e. coli and fecal), nitrate, nitrite, nitrogen, ammonia, pH, phosphorus, sulfide, TDS, conductivity and turbidity. Other instruments that may be included are, but are not limited to, a turbidity meter, colorimeter and UV lamp.
In one embodiment, workstation 6 may be a breadboard for configuring electrical circuits. Breadboards are one of the most fundamental pieces of equipment when learning how to build circuits. Many years ago, when electronics were big and bulky, users would employ a breadboard, a few nails or thumbtacks, and start connecting wires onto the board to give themselves a platform on which to build circuits. An electronics breadboard (as opposed to the type on which sandwiches are made) is actually referring to a solderless breadboard. These are great units for making temporary circuits and prototyping, and they require absolutely no soldering. For those new to electronics and circuits, breadboards are often the best place to start. They can house both the simplest circuit as well as very complex circuits. Another common use of breadboards is testing out new parts, such as Integrated circuits (ICs). When one is trying to figure out how a part works and constantly rewiring, a user would not want to solder connections each time. If one is not sure how a circuit will react under a given set of parameters, it is best to build a prototype and test it out. Prototyping is the process of testing out an idea by creating a preliminary model from which other forms are developed or copied, and it is one of the most common uses for breadboards.
Terminal Strips 106 comprise rows of metal strips on the bottom of the breadboard. The tops of the metal rows have clips that hide under the plastic holes. These clips allow one to stick a wire or the leg of a component into the exposed holes on a breadboard, which then hold it in place. Once inserted, that component will be electrically connected to anything else placed in that row. This is because the metal rows are conductive and allow current to flow from any point in that strip. Each horizontal row is separated by a ravine 103, or crevasse, in the middle of the breadboard. Ravines 103 isolate both sides of a given row from one another, and they are not electrically connected. Each side of a given row is disconnected from the other, leaving the user with five spots for components on either side.
Power rails 108 typically run vertically along the sides of breadboard 100. Power rails 108 may be metal strips that are identical to the ones that run horizontally, except they are, typically, all connected. When building a circuit, one tends to need power in lots of different places. The power rails provide easy access to power wherever it is needed in the circuit. Usually power rails 108 will be labeled with a ‘+’ and a ‘−’ and have a red and blue or black stripe, to indicate the positive and negative side.
Ravine 103 that isolates the two sides of a breadboard serves a very important purpose. Many integrated circuits, often referred to as ICs or, simply, chips, are manufactured specifically to fit onto breadboards. In order to minimize the amount of space they take up on the breadboard, they come in what is known as a Dual in-line Package, or DIP 104. DIP chips have legs that come out of both sides and fit perfectly over ravine 103. Since each leg on the IC is unique, one does not want both sides to be connected to each other. That is where the separation in the middle of the board comes in handy. Thus, one can connect components to each side of the IC without interfering with the functionality of the leg on the opposite side.
Many breadboards have numbers and letters marked on various rows and columns. These serve to help guide users building circuits. Circuits can get complicated quickly, and all it takes is one misplaced leg of a component to make the entire circuit malfunction or not work at all. If one knows the row number of the connection, it makes it much simpler to plug a wire into that number rather than eyeballing it.
Some breadboards come on a platform that may have binding posts 102 attached. These posts allow one to connect various, different power sources to breadboard 100. When it comes to providing power to breadboard 100, there are numerous options. If one is working with a development board such as an Arduino, then one can simply pull power from the Arduino's female headers. The Arduino has multiple power and ground pins that one can connect to the power rails or other rows on a breadboard. Connecting the Ground (GND) pin from an Arduino to a row on a mini breadboard. Now any leg or wire connected to that row will also be connected to Ground. The Arduino usually gets its power from the USB port on a computer or an external power supply such as a battery pack or a wall wart. The first step to using binding posts 102 is to connect them to the breadboard using jumper wires. Although it would seem that binding posts 102 are connected to the breadboard, they are not. If they were, one would be limited to where one could and could not provide power. Breadboard 100 is meant to be totally customizable to provide a wide swath of teaching possibilities. It makes sense that binding posts 102 are no different. Typically, one only needs to connect a power and ground wire from the binding posts 102 to breadboard 100. If one need an alternate power source, you can use another binding post 102.
Different methods may be used to connect power to binding posts 102, and, thus, to breadboard 100. Many electronics labs have benchtop power supplies that allow one to provide a wide range of voltage and current to a prototype circuit. Using a banana connector, not shown, one could provide power from the supply to binding posts 102. Alternatively, one could use alligator clips, IC hooks, or any other cables with a banana connection to hook breadboard 100 to a number of different power supplies. Alternatively, a student may pull power directly from a computer via USB connections.
Workstation 6 may include notifiers 8, such as for purposes of example only, analog and digital taps, that would allow the professor to see how the student is progressing with the lab instruction. Other types of communication that may be integrated with workstation 6 include texting and video display abilities, such as via a display view screen 7, as known to those of skill in the art. For purposes of example only, written instructions and the ability to display graphics to communicate electronic schematics as hand-drawn sketches via view screen 7 would aid with real-time directions and instruction. Additionally, workstation 6 may be able to display simulations and provide auto prompts for achievement recognition to students, as known to those of skill in the art, via view screen 7 and/or speaker 9
Video analyzer 4 may also incorporate an infrared camera 5 for determining and locating hot spots or heat plumes on workstation 6. The instructor at a distance could readily use the indication of a hot spot or heat plume information as a pivotal moment to further guide the student. In one embodiment for electronic laboratory embodiments, video analyzer 4 would have infrared capability to see hot spots on the breadboard; helping the instructor to better “see” what the student was doing on the breadboard via the heat emissions produced by the assembled circuitry on the board. This would be a significant improvement over in-class instruction as an instructor would be incapable of seeing these heat blooms with the naked eye.
Further, device 2 may include an articulation arm 11. Incorporation of articulation arm 11 may provide multi-dimensional interaction between instructor and student over a distance. Articulator arm 11 could be termed a “robot arm” by most modern definitions and could employ robotic arms as known to those of skill in the art. Articulator arm 11 may be capable of full rotational movement as well as movement in the X, Y, and Z planes with respect to attachment point 17. In one embodiment, video analyzer 4 may be affixed to articulator arm 11. In a further embodiment, a second video analyzer 13 may be affixed to proximal end 15 of articular arm 11. In a further embodiment, multiple articulator arms 11 may be housed in one automated remote learning device 2. In this way, articulator arms 11 may interact with one another to demonstrate techniques, such as knot tying, proper handling of a test tube, how to clean a spark plug, how to prepare a culinary dish, demonstrating how to agitate a sample, etc.
Video analyzer 4 may in one embodiment comprise a two-way camera, that, in association with view screen 7, allows the student to also see the instructor. Device 2 also includes an indicator 12. Indicator 12 will enable the professor to direct the student's attention to portions of workstation 6. Indicator 12 would need to be a device capable of pointing to or indicating portions of workstation 6, such as a light, pointer, or laser. In one embodiment, indicator 12 may be a laser pointer mounted on articulator arm 11, which allows the professor to have remote control of the position of the laser pointer and to direct the student's attention to various sites on workstation 6 by pointing to particular parts thereof.
Indicator 12 in conjunction with video analyzer 4 would allow the professor to follow the student's progress, as well as instruct the student on how to make changes to workstation 6, if correction of the lab exercise is needed. Further, device 2 may include a two way communication platform 16. Two way communication platform 16 may include audio and/or visual two way communication as known to those of skill in the art. In a further embodiment, two way communication platform 16 may be integrated with video analyzer 4. In one embodiment, two way communication platform 16 may be capable of communication via a software application such as Skype, Google Hangouts, VoIP call, VSee, UberConference, GoToMeeting, Webex, Voca, Viber, oovoo, etc., as known to those of skill in the art. At essence, communication may be accomplished via software that requires no more than an internal or external camera and microphone, which may be built into device 2 and an active Internet connection. An internet connection may be established via a modem/router 19, as known to those of skill in the art.
Further, processor 21, software 23, and memory 25 may be incorporated into device 2 in order to provide instructions to a student via forums such as PowerPoint, screen shot captures, or to simply deliver content from the instructor. In one embodiment, a Raspberry PI, which uses LINUX or Windows based operating systems, or others as known to those of skill in the art, may be used with Python Language software. Further, a 120 GB memory could be employed. The Raspberry PI board may host 120 GPIO pins, an HDMI port, a USB port, two camera ports, a SD connector and two display ports. Python software language may be used to generate code and subroutines while using an open source, or proprietary, library calls to facilitate video streaming, remote control, GPIO and hypertext interface. In addition, two way communication platform 16 may have audio/video recording capabilities, as known to those of skill in the art, in order to allow a student or instructor to capture activity occurring within a device 2 and create a data cache 27 for later playback, manipulation, discussion, etc., of the captured information. Two way communication platform 16 may also use processor 21, software 23, and memory 25 to enable language translation to overcome communication difficulties between speakers of different languages.
A router may connect multiple networks and may route network traffic between them. The router may have one connection to the Internet and one connection to a private local network, such as device 2. In addition, the router may contain built-in switches that allow for connection of multiple wired devices. The router may also contain a wireless radios for connection with Wi-Fi devices. The modem may serve as a bridge between the local network, such as device 2, and the Internet. Historically, the term “modem” is shorthand for modulator-demodulator. The modem connection to device 2 may depend on the type of connection. The modem may plug into whatever type of infrastructure you have—cable, telephone, satellite, or fiber—and gives a standard Ethernet cable output that can plug into any router (or a single computer) and obtain an Internet connection.
In one embodiment, workstation 6 may include a modified breadboard, such as an Automated Remote Learning (“ARL”) Breadboard. A typical breadboard would not have taps for voltage measurements, whereas an ARL Breadboard would be voltage measurement capable, as well as include analog and digital capabilities. As shown by
Example. Level Detector. In one embodiment, a distance learning experience may be employed to educate students regarding circuit schematics and physical rendering. For instance, a distance learning event may be designed around teaching a student(s) how to construct an analog circuit. For instance, the learning experience may be to energize a relay automatically with a decrease in light level as seen by a photo resistor or manually energize or de-energize the relay through start/stop buttons. The sensitivity of the level detection can be adjusted with a 10 k trim pot.
One embodiment of a distance learning event could teach a component/subsystem type of assembly, moving from left to right on
As students learn to place components on a breadboard, mistakes are common. However, with the assistance of indicator location 50, which in one embodiment, may be a laser dot produced by a laser pointer such as indicator 12, which may also be accompanied by voice and/or video communication, the instructor may use indicator location 50 to assist the student in properly placing items on the breadboard, see
As explained above, the previous example depicted a single step. Another learning experience may have 2, 3, 4, or more, subsystems, all of which may be broken down into directable and testable multi-step learning experiences. Indeed, the previous example may be leveraged to provide Automated Remote Learning at a distance for the entire circuit during a lab event. Visual inspection and analysis of voltage measurements from the student's ARL breadboard 30 occurs throughout the entire circuit from input to output—this allows for teaching as well as troubleshooting problem areas.

Example. Modification of circuit.
Thus, as described supra, the current disclosure allows for two way interaction by, for purposes of example only and not intended to be limiting, pointing a laser pointer, or other indicator, at different parts of workstation, such as a breadboard and circuit, while advising the student though voice and/or video communication. This may enable several students spread out in remote areas to actively participate in a laboratory learning environment with a central instructor, located at a distance from the students, via this effective and efficient new way to aid in the building of electronic circuits.
One problem the current disclosure addresses is best summarized by the tendency of the student to shift accountability from themselves to their surroundings for a malfunction in their circuit. When the instructor is present, any touching or manipulating of the student's circuit can be morphed into the words “it was working before you messed with it.” This is overcome by the current disclosure, which circumvents the “if you touch it then you own it” defense of students creating non-functional experimental setups. Thus, the current disclosure, as a precautionary mantra, only points and guides but does not to physically interact with the circuit and board to an extent sufficient to change the configuration of same. The current disclosure places the instructor anywhere except near the circuit and board, thus eliminating accountability shifting.
An added benefit of this invention will be the omnipresence gatherings of information on the individual, group or effectiveness during the procedural steps are seen as quantitated measurements acting as a function of time. In these models a host of known variables and yet to be determined variables can undergo the scrutiny of causality. Furthermore when the physiological and other factors are quantified and modeled the student's performance can be better understood thus moving from the antidotal realm to the hard science of study.
This invention also provides a benefit that addresses the problem of remotely installing a “bug” or fault. These “bugs” could be communicated with the five senses such as the sound of a relay “clicking” on and off or the smell of an overheated resistor. A better teaching of troubleshooting occurs when the addition of “bugs” into the circuit on the breadboard at seemingly random moments. Through the distance learning method an instructor will be able to add “bugs” into the circuit and will be remotely installed appearing as an random event. For example, in the same proximity as the analog taps on the bread board, transistor switches may be placed so as to introduce “bugs.” For example, the note between a photo resistor and fixed resistor may be grounded remotely via the transistor (acting as a switch) via GPIO used by the remote instructor. This example may be further extended not only to grounding but also biasing. A yet further example would be to ground input pings of an onboard ICS. A further example would be to pull output pins of onboard ICS via transistor using GPIO under the control of the remote instructor. Another example could be to incite a short circuit appearing as a low resistance path between analog tap locations. This example would be effective to provide a student with the experience of locating a shorted transistor or as a push-button malfunction.
In a further embodiment, automated remote learning devices 2 may form network 212 by allowing for two-way communication 214 between devices 2. (Additionally, students may be allowed to communicate with one another over network 212 or another network established amongst units 2.) By allowing devices 2 to form a network 212, a rudimentary neural network may be formed amongst units 2 in use within a class of students. Further, communication platform 16 may contain a processor 21 that may use software 23 to evaluate a student's use of device 2. In this way, devices 2 could have built in “assistance” for students based on a history of use across the network, either via the current class experience or previous ones. This would enable students to learn from past users of a device 2 via software 23 interacting with the student via communication platform 16 in the form of a helpful hints data file, videos, etc., that a student might access if they encountered an issue or simply wanted to learn more about device 2. In addition, communication platform 16 may provide video, audio, sensory or other notifiers to students if a project is wrong, such as, for purposes of example only, a red light, a buzzer, flashing light, or burning smell if a circuit is assembled incorrectly. Other indicators, such as a green light, ding, or other means could be used to signify success.
