Writing Across the Curriculum Rationale:

MCC Form EDU 0007 (rev. 1208/2006)

3 Mohave Community College firmly supports the idea that writing can be used to improve education; students who write in their respective content areas will learn more and retain what they learn better than those who don’t. Courses in the core curriculum have been identified as “Writing Across the Curriculum” courses. Suggested minimum standards for the Writing Across the Curriculum component are as follows: 1. The writing assignments should total 1500 – 2000 words. For example, a single report which is 1500 words in length could fulfill the requirement, or a series of essay questions and short papers (example: four -375 word assignments) which total 1500 words could meet the requirement. 2. The writing component will represent at least 10% of a student’s final grade in the course. Is this a course identified as a Writing Across the Curriculum course?

__ Yes

X__ No

Intended Course Outcomes

By the end of the semester, students will be able to: 1. Develop freehand sketches quickly and accurately. 2. Freehand sketch three-dimensional objects, auxiliary views, and sectional views. 3. Demonstrate freehand lettering techniques that conform to ANSI standards. 4. Produce accurate freehand drawings of objects including, correct dimensioning and placement.

Course Competencies and Objectives Competency 1 Demonstrate the use of freehand lettering techniques. Objective 1.1 Demonstrate lettering that conforms to ANSI (American National Standards Institute) standards. Objective 1.2 Compare and contrast a drafting type pencil, lead holder and technical pen, and discuss the best use of each. Objective 1.3 Demonstrate the correct steps for forming letters following the recommended sequence to ensure correct proportions. Objective 1.4 Demonstrate the correct sequence for forming typical curved line letters. Objective 1.5 Define “mono-spaced text” and give an example of when it is used. Objective 1.6 Describe and demonstrate the use of isometric lettering. Competency 2 Demonstrate the use of freehand sketching to illustrate an idea or mental image on paper. Objective 2.1 List the variety of tools designers use when sketching.

Describe the purpose of grids and demonstrate their use. Demonstrate how to annotate sizes and proportions for a design Demonstrate how to measure the points on a circle. List the rules use to locate tangent points. Create a pictorial sketch of a three-dimensional object. Demonstrate the use of visualization to assemble individual surfaces Compare and contrast pictorial vs. orthographic views. Demonstrate how to convert pictorial ideas into orthographic form. Demonstrate the process for converting orthographic drawings into List and describe the commonly used dimensions for objects. Demonstrate how to transfer depth, using dividers, paper method and List the most common line codes used on drawings.

Competency 4 Visualize unique surfaces in space, and predict the appearance of each surface in each view. Objective 4.1 Describe normal surfaces. Objective 4.2 Translate the normal surface table for each of the views. Objective 4.3 Break objects into individual surfaces in order to analyze the object. Objective 4.4 Predict the shape, size and appearance of an object in regular views. Objective 4.5 Utilize the normal surface and edge charts to prove lines and surfaces of a drawing. Objective 4.6 Analyze surface locations by using the rules for normal surfaces. Objective 4.7 Demonstrate the correct procedure for proving inclined surfaces. Objective 4.8 Describe oblique and cylindrical surfaces and discuss when they are used. Objective 4.9 List and describe the two forms in which cylindrical surfaces may be illustrated. Competency 5 Illustrate auxiliary and sectional views and describe why they are used. Objective 5.1 Describe the purpose of an auxiliary view, and demonstrate projecting auxiliary views from the front, top and side. Objective 5.2 Describe the purpose of a sectional view. Objective 5.3 Demonstrate sketching solid areas by adding visible lines. Objective 5.4 Describe how sectional line codes are used to illustrate different materials. Objective 5.5 Compare and contrast the use of phantom, half section, and revolved section views. Competency 6 Specify fasteners on drawings, indicating proper size, strength and finish. Objective 6.1 Describe and demonstrate how to specify threads on a drawing. Objective 6.2 Define thread pitch. Objective 6.3 Compare and contrast ACME, SQUARE and BUTTRESS threads. Objective 6.4 Demonstrate the illustration of bolt clearances, countersink holes,

5 blind threaded holes, set screws, keys, pins and lock washers. Competency 7 Demonstrate the use of basic dimensioning techniques. Objective 7.1 Describe the use of dimension, extension and leader lines. Objective 7.2 Demonstrate the use of size, location, pattern, machine and mating dimensions. Objective 7.3 Accurately utilize dimension lines for arcs, circles and cylinders. Objective 7.4 Analyze the advantages and disadvantages associated with the use of too many or too few dimension lines. Competency 8 Objective 8.1 Objective 8.2 Objective 8.3 fits. Objective 8.4 metric systems.
