The Worcester State University Library has called for proposals for Open Educational Resources Initiative (OERI) mini-grants to support Fall 2017 courses to the use of Open Educational Resources.
I have submitted a proposal to support the use of OER in CS 343 Software Construction, Design, and Architecture. This is the first required course in our Software Development Concentration in the Computer Science Major, and is taken by students in the concentration in the Fall of their Junior year.
Rather than repeat material from my mini-grant proposal, I’m just going to reproduce my submission here. Whether I receive the mini-grant or not, I will still be doing this with my course, and I will blog about it here as I work on it.
Course Number
CS 343
Course Title
Software Construction, Design, and Architecture
What type of course is this?
LASC Required course in the major Elective course in the major
Number of Students
Please estimate the enrollment of the course, either using data from previous semesters (average or aggregate), exact enrollment from the last time the course was taught, or, if proposing a new course, an estimate of anticipated enrollment.
Currently 33 registered for Fall 2017. (Another 5-10 are likely when transfer students register.)
(There were 26 students in the last offering in Fall 2016.)
(This course is a first-semester junior-year course required of all Software Development Concentration students in the CS Major, offered every Fall semester.)

What are your goals regarding this initiative? What are your intended outcomes for your students’ learning?
I am redesigning this course from scratch and there is no single textbook that covers the range of material that I want to include in this course.
My plan is for this course to cover the design of software systems, as represented by design patterns and software architectures. The students will design software systems, and construct some of them from those designs, in some cases using available software frameworks. The unifying theme for these three design topics (design patterns, software architectures, and software frameworks) will be the concept of modeling these designs using the Unified Modeling Language (UML) as a representation.
To implement this plan, I will need to find resources covering four areas:
- Learning the most commonly used diagrams in the UML and learning to use a modeling tool to create the models and diagrams.
- Learning about the most commonly used design patterns, and to what types of problems they should be applied.
- Learning about a number of commonly used software architectures, to what types of problems they should be applied, and how to design with them.
- Learning about a number of commonly used software frameworks that correspond to some of the architectures, and how to implement a design/system with them.
By using OER materials for:
- The UML – I will be able to pick and choose which diagrams we cover, and to what level of detail. Students will not need a textbook that is larger than needed. In addition, we will have access to instructions for using the most recent version of the modeling tool, and students will not have to translate from a different tool that might be used in a textbook.
- Design Patterns – I will be able to pick and choose which patterns we cover, and to what level of detail. Students will not need a textbook that is larger than needed. In addition, I will be able to find more relevant examples of the design patterns for the students.
- Software Architectures – I will be able to pick and choose which architectures we cover, and to what level of detail. Students will not need a textbook that is larger than needed. In addition, I will be able to find more relevant examples of the architectures for the students.
- Software Frameworks – I will be able to pick and choose which frameworks we cover, and to what level of detail. Software frameworks are not typically covered in textbooks. In addition, we will be able to use the most up-to-date versions of appropriate frameworks, which change quite frequently.
Finally, it will be easier to have the course materials reflect the current state of software design for future semesters, as a textbook would go out of date quickly and not be updated as frequently.
Please give a brief description of the plan for which you seek support. This might include how you will go about identifying or creating resources to replace the materials used in your course, how students will access the assigned content (e.g., via laptop, mobile device or smartphone), how you will make your educational resources openly available, etc.
There are literally hundreds of online tutorials and blog posts about the four areas I want the course to cover. There may be some materials in some of the open content and open textbook databases, but I am not having as much luck with those. The difficulty will be determining which of the materials are of high enough quality and at the right level for the students. The bulk of my effort will be put into finding and reviewing the materials. Once the materials have been identified, compiling them into lessons and background reading for assignments will not be too difficult.
As the materials I am looking at are mostly Web resources, the students will most likely be accessing them on their laptops, although access through a mobile device will be possible.
All materials that I produce myself (syllabus, lists of readings and resources, lessons, assignments, project specifications, and tutorials) will be licensed CC-BY-SA (which I have been doing for years) and will be available on the GitHub repository for the course. I will look into which of the OER sites is the most appropriate for posting to as a directory to link to my materials.
What challenges do you anticipate in implementing your goals? (e.g., time constraints, technology barriers, etc.) How do you plan to address those challenges?
The biggest challenge will be having enough time to review the large quantity of web materials. Another challenge will be the fact that I am still designing the course, as I am researching materials.
I plan to address those challenges by adopting a “good-enough” approach and finding something good enough for each topic first, and then when additional time is available, looking for better materials before the topic is covered (or after the course has ended to prepare for the next offering.)
What library or other support will your project require?
I have not spent any significant time investigating library resources, particularly database and ebook offerings. Spending some time with one of the librarians to look at what is available will be helpful.
How do you plan to assess the effectiveness of this initiative? Will you be able to participate in library assessment?
I will blog about my efforts to design the course and select materials. I will survey the students on the materials themselves. I plan to have the students spend time looking for materials themselves and blogging about them as part of the course, in service of our program outcome:
“Learn new models, techniques, and technologies as they emerge and appreciate the necessity of such continuing professional development.”
I will give the students both the Pre-Test and Post-Test that the Library develops to assess the OER Initiative.

Yesterday was International Weblogger’s Day, and in honor of the day I’m going to make a resolution to post on my blog at least once a week. (Let’s see how well that goes…)

I am preparing for a new (for me) course for the Fall 2017 semester: CS 343 Software Construction, Design, and Architecture. My intention is for this to be a course primarily about software design and I want to approach it through design patterns, software architectures, and modern software frameworks. These are all topics that I have read a little about, but not enough to really teach. So, I am spending my summer reading a lot about them.
For other courses, I’ve learned little bits of UML (mostly class diagrams, with a very small amount of use-case diagrams, sequence diagrams, activity diagrams, and state diagrams) and all very informal. So, I decided that, if I’m going to teach design, I need a representation for those design patterns and architectures and it’s time that I finally learned UML more formally.
I am currently working my way through the video series UML Fundamentals, Standardized Structural and Behavioral Modeling for System Design by Simon Bennett from O’Reilly Media (6 hours, 12 minutes). So far, it’s pretty good, although it seems almost more about how to create the diagrams in Enterprise Architect (a commercial product) than about UML itself. I’m going to have to read some books about UML also to supplement the videos, but it’s a good introduction.
The commercial tool he uses looks nice, but I would like to find a FOSS alternative to use, both for myself, and for the students to use in class. I’ve played around a little bit with some of the Eclipse tools for modeling, but I’ve not found them very easy to use. So, I’m still looking. If you have any suggestions, please let me know.

The fifth chapter reminded me of chapter 2 in The Clean Coder. I wrote about this in my blog https://rmurphy12blog.wordpress.com/2017/01/25/week-1-the-clean-coder-ch-12/ An important skill to master is the ability to say no. The act of saying no can save you from getting into trouble.
Chapter six is titled “Working Software”. In most cases the code you are working on is going to be around for a while. This means is is just as important to write code that is maintainable as it is to write code that preforms the required task. If code is written in hast, without proper planning it is going to end up costing more time in the long run. I have found this last statement to be true. I once wrote a piece of software rather hastily and did not write a single comment, a few months later I was asked to make some changes to the program. The changes should have been simple, I was just going to add a few features. When I started looking through the code to become familiar with the code I realized there was much I could not remember. I ended up spending a lot of unnecessary time on the project because the first time around I was in a rush.

In the third chapter of The Software Craftsman, Sandro Mancuso discusses what it means to be a software craftsman. One of the first ideas brought up is to be a software craftsman you must be a professional. The topic of professionalism is covered in several of my earlier blogs as it was one of the main themes of The Clean Coder. As a craftsman you are always looking to hone or refine your skills.
The fourth chapter is all about the attitude of a software developer. A true craftsman really cares about there work, the take pride in it. I believe this is very important in all jobs. If you don’t take pride in your work you are more likely to have issues of all sorts.
