educat.ninja Logic Gates Experimental Circuit Set

A modular logic gate set containing NOT, AND, NAND, OR, NOR, and XOR gates, together with logic input boards and splitters.

Suggested/Example Activity Worksheets

Now available via Tindie.com

A logic gate set which allows students to begin to explore Logic with working logic gates, build logic circuits, including half and full adder circuits - combining the two to make a working two-bit (half +full) adder circuit, Universal NAND and NOR gate modelling.

Logic circuits can be build from working physical gates, allowing students a real appreciation for the physicality of the applications of logic circuits.

The Universal kit allows for complex logic circuits to be built and examined including building logic gates from NAND gates and a working adding circuit which can combine a pair of two-bit binary numbers together (a combination of a half and full adder).

Suitable for practical, hands-on, exploratory and experimental lessons allowing students to work independently with minimal teacher talk.

Changes to inputs instantly cascade throughout the circuit

Each gate has LEDs showing the input and output from each gate and the boards have magnetic feet which allow them to be mounted on a vertical whiteboard and the USB-A and USB-C connections ensure that the boards are connected correctly.

There are also a few suggested activities including students discovering for themselves the truth tables for each gate, a structured worksheet allowing them to build a half adder, and more advanced, more challenging activities for higher ability students, building each gate from the universal NAND and NOR gates through trial and error and perseverance, rather than relying on the internet to simply give them the answer.

allows logic circuits to be modelled such as a two input bit (half) adder

The magnetic feet and 3m power cable allow the circuits to be mounted on vertical whiteboards for group demonstrations.

The kit can easily be powered from any USB-A charger or power-bank with the 3m USB power cable.

More complicated arrangements are possible, below is the half and full adder combination.

Exam topics - Student Graphical Analysis

Show your student how they performed on each topic in the test.

This will require openoffice which is a free alternative to microsoft office and can be downloaded from https://www.openoffice.org/

You can download the file from the following link https://educationalelixirs.com/files/examtopicsV1.ods

Before any marks can be added to the spreadsheet, it is necessary to look through the exam papers and make a note of the topics of each question and the maximum mark available for each section. The goal is to divide the paper into the smallest number of topic sections.

eg. 

Q1a - Calculations (6 marks)

Q1b - Resistance (8 marks)

Q2-4 - Projectile Motion (13 marks)

Q5 - Resistance and Projectile motion (9 marks)

Q6 - Forces (15 marks)

Select a unique single letter code for each Topic

e.g.

C Calculations

P Projectile Motion

R Resistance

F Forces

This can be entered into the "Exam" Sheet.

For each topic section enter the topics and the number of marks available. The reference row is purely for your reference. Enter the Code(s) for the topics which refer to the question in the top box. It is important to use exactly the same codes as you put into the boxes. You can enter up to 3 topics per topic section (but obviously you'll get more accurate results dividing up the papers into individual topic sections), and do not insert spaces between them - RPC will work R P C (with spaces) will not.

e.g.

Code	C	R	F	P	RP
Mark	6	8	13	9	15
\ Ref	Q1a	Q1b	Q2-4	Q5	Q6

It is, of course, necessary to calculate the marks for each topic section for each student when the paper is marked.

The codes are entered into the Box on the right hand side of the "Exam" sheet.

The averages for each question are available at the bottom, allowing the teacher to see exactly how well the class performed on each of the topic sections.

The MCQ sheet (below), has space for more exam topic sections (as MCQ papers tend to have more questions and exam topic changes). The boxes in yellow cannot be modified, only enter information into the green and blue boxes.

The results sheet

The name of the student can be selected on the graph sheet and the bars should change to reflect the topics - printing this page will result in 1 A4 page being used - alternatively you can always save the pdf in the print dialog.

The Graphs

On the left is how the student achieved in the MCQ, in the short answer exam and a 1:1 average of the two. The graph at the bottom is intended as a revision guide for the student - it arranges the topics in order of weakest to strongest, advising the student to start revising with their weakest one. The graphs on the right hand side show how the student is performing relative to the class average for each individual topic - this particular student performed better than his peers on every topic except the dark green one. Again, the top box is the MCQ, the middle is the short answer exam and then an average of the two.

The revision suggestion at the bottom right is listed in order of the weakest topics relative to the class average.

Please let me know if there are any problems with the spreadsheet.

Free Timetabling Software

FET is open source free software for automatically scheduling the timetable of a school, high-school or university. It uses a fast and efficient timetabling algorithm. It is licensed under GNU GPL.

Usually, FET is able to solve a complicated timetable in maximum 5-20 minutes. For simpler timetables, it may take a shorter time, under 5 minutes (in some cases, a matter of seconds). For extremely difficult timetables, it may take a longer time, a matter of hours.

Electronic Markbook / Pupil tracking system

This spreadsheet functions as an electronic mark book. It automatically tracks the progress of each student against the class average and displays a graph allowing you to see which pupils are beginning to under-perform. It also makes report writing much easier as you can see at a glance how the student has performed over the term.

It automatically calculates the averages for each piece of work completed and can include data columns - for instance mid-term grades and final report grades if required (but the maximum mark box must be EMPTY).

The spreadsheet is automatically weighted and assumes that the importance is related to the maximum number of marks for an assignment - a 55 mark test is 5x as important as a 11 mark prep. This can be changed by entering a value in the weighting column - if you require the 11 mark prep to have equal weighting with the 55 mark test either change the weighting of the test to 11 or the prep to 55 depending on the other marks in the spreadsheet. if you would like all the pieces of work to have equal weighting, then put the same number (any number) along the weighting row.

e.g. 1 1 1 1 1, or 20 20 20 20 20, etc...

Magic UMS (OpenOffice spreadsheet)

MagicUMS is a straightforward UMS calculating spreadsheet. Requires the FREE OpenOffice suite. ( http://download.openoffice.org ) - alternative to Microsoft Office.

It allows you to easily combine the raw marks for up to 3 papers and instantly converts to UMS marks complete with grade achieved. The results can be copied and pasted into word or another spreadsheet.

The tab can be copied and renamed so you can keep the results for different classes on different tabs in a single excel file.

Simply input the maximum mark for each paper, the weighting of the paper, adjust the grade boundaries if necessary and then input the names and marks of each student and the UMS marks and the grade magically appear.

If necessary the names of the grades and the UMS marks awarded for each grade can be changed.

Only the areas in green need to be filled in, the areas in grey can be adjusted if absolutely necessary. If there are less than 3 papers set then the weighting should be set at zero for the unused one. The weighting can be in any ratio 1:4:3 works out exactly the same as 20:80:60.

There is a possibility that the G/U grades are not automatically completed for this version, but hopefully you won't need them!
