NEW WORK


This section of the website documents new work being created and tested by Ian Symonds of EDUTRONIC. This is work in progress and uses some of the material in the Education Archive. Extra new material and new practical work is being created as part of a personal research project. Brief information is given below on the work, and links are included to view the material as it is being developed.

Trial1 Material
(Combinational Logic)


Trial1 Building

Trial1 Testing

The first stage was a "one to one" review and discussion of part of some online material from the archive. It is an introduction to the basic logic gates, AND, OR and NOT. Logic functions combining these basic gates such as NOT AND (NAND) and NOT OR (NOR) are introduced. This is revision, but introduces what is possibly a different approach to that seen initially by the student.

The next stage introduced the use of a simple custom built battery powered logic tutor using 4000 series CMOS chips. The online material to support the practical work is called Trial1 and is in three sections. The first contains the background and the theory for the trial. The second section is support for the design and building of the circuit and the final section is support for testing the circuit.



Test Material for Investigation A

Simple test material to be used by students prior to a semi-structured interview. The aim of the interview is to get student views on the use of the material.



Trial2 Material
(Sequential logic)


The learning and Teaching material will start with an introduction to the LATCH circuit which is an example of a SEQUENTIAL Logic Circuit. This work utilises and builds upon the work on COMBINATIONAL circuits studied in Trial1. The work is in three sections as in Trial1 but includes the use of audio support in some sections. The trial ended with a semi-structured interview, as in Investigation A, to gather data on audio use for later projects



Trial3 Material
(Extended Pilot Study 2019)


The learning and Teaching material will start with a continuation of the SEQUENTIAL material from trial2. Bistables, with the JK device as an example, will introduce the way in which counting is achieved in a digital circuit. The next step uses COMBINATIONAL logic as well to produce PULSE WIDTH MODULATION, PWM, which is a key digital method for control systems and Robotics. It is at this stage that we move to programable digital devices, where the same digital methods can be accessed from software. The work is still in three sections as in Trial1 and includes the use of audio support in some sections. The trial will end with a semi-structured interview, as in Investigation A and trial2, to gather data on audio use for later projects
