Isometric drawings
Published in Bob McFarlane, Beginning AutoCAD 2002, 2012
An isometric is a 2D representation of a 3D drawing and is useful as it can convey additional information about a component which is not always apparent with the traditional orthographic views. Although an isometric appears as a 3D drawing, the user should never forget that it is a ‘flat 2D’ drawing without any ‘depth’.
Why do students choose to study on engineering foundation year programmes within the UK?
Published in European Journal of Engineering Education, 2023
Students were asked to produce a 4–5-minute digital story entitled ‘Why I am studying engineering’ as an assignment for a 10-credit ‘Development of Key Skills for Engineers’ module. The module ran in the first semester of the academic year, for a duration of ten weeks from late September to early December 2018. The syllabus included: identification and assessment of key skills; oral communication (planning, preparation, and presentation, resources, use of slideshow software and videos for communicating ideas); written communication (report writing, information gathering, structure, and content); ICT skills (introduction to computing using MATLAB); graphical communication (orthographic projection, isometric projection, sketching); project work (structure of the project, planning and organisation, brainstorming, review of progress); and networking skills. There were 2 hours of contact time per week which included lectures, example classes and computer labs. The assignment was introduced half-way through the module and was worth 15% of the module mark. Students were introduced to various types of multimedia software which they may utilise to complete their assignment. Although they were asked to include use of slideshow presentation software, they were given a significant degree of flexibility in the format of the submission. They were informed that their submissions would be marked according to the following criteria: video length (between 4 and 5 minutes); their physical presence within the video; the structure of the presentation; quality of content (on topic) text and graphics; quality of production.

Procedure for the Conventional Group: The conventional group students received two implementations of the conventional teaching of ED in four sessions on four separate days (Figure 8). The duration of each session was approximately two hours. Similar to the experimental group, Implementation 1 (sessions 1 and 2) used problems on ‘orthographic projection,’ while Implementation 2 (sessions 3 and 4) used problems on ‘isometric projections.’ At the end of every session, we conducted the same tests on ED problems. Here again, after each test, we collected students’ reflective journals to understand their perceptions of the learning difficulties in ED while solving the tests. Additionally, at the end of all sessions, we conducted students’ interviews to get a deeper understanding of learning difficulties.
Requirements in mathematics textbooks: a five-dimensional analysis of textbook exercises and examples
Published in International Journal of Mathematical Education in Science and Technology, 2018
The content requirements refer to finding out what mathematical knowledge a student should possess in order to solve a particular textbook task. The content field of the Austrian standards is divided into: numbers and measures (coded as I1); variables and functional dependences (I2); geometric shapes and solids (I3); and statistic representations and parameters (I4). These content fields follow the current national curriculum for the lower secondary level of mathematical education. Numbers and measurements encompass integers, rational and irrational numbers, arithmetic operations and measurement units. Variables and functional dependences involve terms and formulas, equations and linear equation systems, proportionality and linear and quadratic function. Geometric shapes and solids refer to 2D and 3D shapes, similarity, isometric functions in the plane, Pythagorean theorem, circumference, area, surface area and volume of geometric shapes. In this framework, the statistics content refers to representations of statistical data, probability and random event.
