DESCRIPTION OF EMBODIMENTS
[0043]
[0044]
[0045] The circuit board layer 110 comprises a printed circuit board on which a portion of an electrical circuit is provided. In particular, first and second terminals 120 are provided on the circuit board layer, between which the portion of the electrical circuit extends.
[0046] In the example of
[0047] The terminals 120 enable the teaching aid 100 to be dynamically connected to other aids 100, to a power source, and to other electrical components, to generate complete circuits. As outlined in further detail below, a plurality of teaching aids 100 are advantageously coupled to each other during a class to illustrate electrical concepts to the students.
[0048] The schematic layer 115 is placed above the circuit board layer 110 and graphically provides a schematic of the portion of the electrical circuit of the circuit board layer 110. The schematic is printed in contrasting colour (e.g. black on white) and is large so that it can be seen from a distance, e.g. from a back of a classroom.
[0049] The schematic layer 115 includes a resistor element 115a, and first and second wire elements 115b. The first and second wire elements 115b extend from the terminals 120, and as such, the schematic layer 115 and the circuit board layer 110 are aligned at the terminals. As such, when a circuit is generated with the teaching aid 100, e.g. by coupling a plurality of teaching aids 100 together, a schematic is generated (from the schematic layer(s) 115 and physical wires), as well as an electrical circuit (from the circuit board layer 110 and the physical wires).
[0050] As such, visual representation of the circuit (i.e. the schematic) is inextricably linked to the actual circuit. This allows the teacher to demonstrate a circuit physically (practically) and theoretically in the same time and space and through a single action.
[0051] The magnetic backing layer 105 enables the system 100 to be coupled vertically, e.g. on a whiteboard. As such, circuits can be generated in a manner which enables them to be easily seen by a plurality of students, and in a classroom setting. Also, by using the aids 100 in a traditional theoretical setting (i.e. a classroom), practical observations may be made by students within this environment, which can enhance retention of information.
[0052] As best illustrated in
[0053] In an alternative embodiment, the circuit board layer 110 includes a peg, or handle, which is configured to enable the user to pull the teaching aid 100 directly from the surface. Advantageously, the peg or handle is located at a corner (e.g. the bottom right corner) which is both functional (it is easier to remove the teaching aid 100 from a corner), and aesthetically pleasing (it does no shield the schematic layer 115).
[0054] The schematic layer 115 advantageously covers more than half of the circuit board layer 110, to provide an efficient view of the schematic to the user. In particular, the wire elements 115b are much thicker than the tracks 130, which enables the wire elements 115b to be seen from a much further distance from the aid 100 than the tracks (which may not be visible unless very close to the aid 100). Similarly, the resistor element 115a is much larger than the resistor 125.
[0055] According to certain embodiments (not illustrated), the teaching aid 100 includes a Quick Response (QR) code that provides a link to media relating to the circuit. As an illustrative example, the QR code may comprise an encoded Uniform Resource Locator (URL) linking to an online video describing or clarifying the circuit. The QR code may be positioned on the circuit board layer 110, adjacent to the circuit. Such positioning enables easy access to the QR code while in use (e.g. be scanned by a smartphone of a student), while not distracting from the schematic of the schematic layer 115 when viewed from a distance.
[0056]
[0057] The electronic teaching aid 400 includes a circuit board layer 405, similar to the layer 105, but with the light 425 soldered thereto. Similarly, the electronic teaching aid 400 includes a schematic layer 415, similar to the layer 115, but with a light element 415a between the wire elements 115b (and terminals 120).
[0058] The skilled addressee will readily appreciate that the circuit board layers 110, 410 of the teaching aids 100, 400 may be provided without the resistor 125 or light 425, and be configured such that a teacher (or other suitable person) solders a desired component onto the circuit. In such case, the circuit board layers of the teaching aids 100, 400 may be identical initially, and be adapted to incorporate a resistor, light, or other suitable component. A suitable schematic layer 415, 115, may then be added thereto.
[0059] Furthermore, circuit board layers may be provided that have a plurality of alternative circuit configurations, as outlined below. Such setup may reduce manufacturing costs, as a single circuit board layer can be produced for multiple different configurations. Furthermore, such setup may provide increased flexibility, as kits may be provided for completion at schools, where the configurations may be selected as needed.
[0060]
[0061] The circuit board layer 500 includes four (4) configuration zones 505a-d illustrated on its first side, and may include a further four (4) configuration zones on its second side (not illustrated).
[0062] Each of the configuration zones 505a-d is provided on an edge of the circuit board layer 500, which is substantially rectangular in shape. As such, components may be installed into one of the zones 505a-d to generate a circuit board layer 500 for use in a teaching aid, such as the teaching aid 100 or teaching aid 400.
[0063] The configuration zones 505 are non-overlapping at their edge, and as such, may be used with a schematic layer of fixed size. In particular, the circuit board layer 500 may be rotated (and turned if double sided) so that a desired configuration zone 505 is provided at a lower end of the circuit board layer 500. Components are then soldered thereto, and a magnetic layer and schematic layer are attached to complete the teaching aid.
[0064] In other words, above each configuration zone 505a-d is associated with a corresponding schematic zone 510a-d. Each configuration zone 505a-d and schematic zone 510a-d pair fills the entire circuit board layer 500 such that each schematic zone 510a-d covers all other configuration zones 505a-d.
[0065] As a result, each configuration of the circuit board layer 500, when a schematic layer is installed onto a schematic zone 510a-d, results in a teaching aid where all other (alternative) configurations are hidden, thus providing a clean (and easy to understand) teaching aid.
[0066] Each configuration zone 505a-d includes a plurality of predefined tracks 515 that define part of the circuit. The tracks 515 extend from pads 520, i.e. portion of metal on the surface of the board to which a component is to be soldered, or from an annular ring 525, i.e. a ring of metal around a plated through hole to which a terminal is to be soldered.
[0067] The pads 520 are placed to simplify installation of various standard components. For example, the pads 520-a are configured to be used together with an 8-pin dual in-line package (DIP) Integrated circuit (IC) chip, and the pads 520-b are configured to be used together with a three-way switch and three alternative components.
[0068] The above described circuit board layer 500 is also particularly useful in that allows teaching aids to be repurposed. As an illustrative example, a teaching aid may be stripped back to the circuit board layer 500, upon which a new configuration is chosen and new components are installed. This is particularly useful as a school's needs change over time.
[0069]
[0070] The educational aids 605 may be similar or identical to the aid 100 of
[0071] Electrical wires 610 are used to couple the educational aids 605 through their respective terminals 120. The wires 610 have an outer plastic layer, which both protects the conductive material of the wires 610 and which makes them large and easy to see. As such, when a circuit is generated between the aids 605, a clear schematic of the circuit is illustrated by the wires 610 and schematic portions 615 the aids 605.
[0072] Furthermore, the wires 610 and circuit layers of the aids 605 provides an actual circuit from circuit portions 620, corresponding to the schematic, which enables a reach to demonstrate the circuit without interruption. As an illustrative example, once the circuit is completed (i.e. coupled), the teacher may connect a multimeter to different parts of the circuit (e.g. to terminals) to demonstrate theoretical concepts. For example, the teacher may illustrate a voltage drop across the resistor by coupling the multimeter to the first and second terminals of the educational aid 605 comprising a resistor.
[0073] Furthermore, the teacher may dynamically reconfigure the circuit by adding and removing educational aids 605, and/or by coupling the educational aids 605 in a different manner.
[0074] While the above embodiments have been described with reference to electrical circuits, the skilled addressee will readily appreciate that other types of circuits may be used, including electromechanical circuits, pneumatic circuits, hydraulic circuits, a combination thereof, or any other suitable circuit.
[0075] Similarly, while the embodiments have been described in the context of a teacher in a traditional classroom, the skilled addressee will readily appreciate that the teaching aids may be used in other contexts, such as in lecture style environments, in labs, and in any suitable educational context. For example, the teaching aids may be used in a demonstrative manner by a teacher, or in an interactive manner by the student(s).
