Applied Technical Mathematics For Diesel Mechanics and Horticulture Students
Overview
Applied Technical Mathematics for Horticulture and Diesel Mechanics is intended for a one-semester class with students who enter the semester with a good working-level of math skills. High school algebra and geometry are the only prerequisites,
The technical math course at Kishwaukee College is unique in that the class combines students in horticulture with those from diesel mechanics. The course materials apply to both areas, as much as possible. The intent is to provide a solid foundation for solving job-related math problems for all students in the class. For this reason, the focus is on "how to solve" more than "why does this work?"
Feedback, comments, etc. would be greatly appreciated!

Preface
Technical Mathematics for Diesel Mechanics and Horticulture is designed for a 3-credit hour class for students majoring in diesel mechanics or majoring in horticulture.
The two fields, diesel mechanics and horticulture, each require an ability to perform on-the-job math. The math skills needed for the two fields have much in common, as well as some things that are different. This text includes material from both fields in sufficient depth to develop competence.
Comments, questions, comments, and corrections are welcomed.

Introduction
Introduction
Applied Technical Mathematics for Horticulture and Diesel Mechanics is intended for a one-semester community college class with students who enter the semester with a good working-level of math skills. High school algebra and geometry are the only prerequisites. The textbook was created for use within Open Illinois in OER Commons and is available for by other OER organizations. The textbook is specifically designed for classes containing students in both horticulture and diesel mechanics.
The technical math course at Kishwaukee College is unique in that the class combines students in horticulture with those from diesel mechanics. The course materials apply to both areas, as much as possible. The intent is to provide a solid foundation for solving job-related math problems for all students in the class. For this reason, the focus is on "how to solve" more than "why does this work?"
Inspiration for this work came from many semesters of teaching technical mathematics. Students in these classes were from the fields of diesel repair and from horticulture; their interests were strictly toward on-the-job applications. To meet this need, this text is focused on various job situations, and emphasizes:
- How to recognize what is needed: Exactly what is the problem asking? How does it apply to a job situation? What sort of answer do you need? (I.e., Do you want the answer to several decimal places, or is a good estimate enough?)
- What to do while setting up the issue in terms of a mathematical problem
- How to solve it
- Recognizing that there often will be more than one solution method
- Ways to see if the last answer makes any sense.
- When to take a hard stand if challenged on an answer.
- Think things through before you do anything.
- If you are being pressed for an answer, demand enough space so you can figure it out.
- Check your work before showing it to anyone!
- Do not ever release an answer unless you are absolutely certain and can explain why.
- But do not be so stubborn that you get a reputation for being hard to work with.
A highly stressed approach is to get a sense of what you are looking for: Before doing the math. For example, if a student is asked to calculate the volume of a semitruck gravel trailer, then estimate the loaded weight, what would be a reasonable answer? Maybe it is 5 tons, or maybe 35. It probably is not a quarter of a ton, or 500 tons. I.e., do not rely on a calculator too much. Consider your answers with the “does this make any sense?” test.
A chapter is included on MS Excel, which few students knew before entering the class. Excel is so ubiquitous in the working world that nearly all tech math students need to have at least a basic knowledge of this software.
The textbook starts with fractions, which almost nobody likes but everybody needs. It is the author’s belief that the foundation for technical math is an ability to work well with fractions. Further course work is intended to teach students how to frame a problem, how to understand what the problem means in terms of why somebody is asking, and how to solve it in any one of several possible ways.
The order of chapters is based on past schedules in my tech math classes. The order can, and does, vary amongst instructors. The order I have chosen is what has worked in my experience.
It is my great hope that this OER textbook will be beneficial to students. My intentions are for anyone who uses this to become thoroughly knowledgeable about the subject materials.
Any comments, corrections, questions, complaints? Please send me an email. All feedback is greatly appreciated.
