BEFORE THE YEAR BEGAN BEHIND THE SCENES

Why Statway™? Students haven’t been choosing to take statistics because they see it as hard, even when the faculty in their majors talk with them about why it would be useful. We haven’t had a good prerequisite course for Elementary Statistics.

How did we organize it? A two-semester sequence (fall and spring) Math for Stat I Developmental math 4 contact hours MATH 1342 (special section) 3 contact hours + Math for Stat II Developmental math 1 contact hour The two Math for Stat courses are new courses we created.

Why that organization? Our department insisted. Better for transferability. There are some hassles, but we think it is a good choice overall.

Who is eligible? Placement into Elementary Algebra College-level reading skills In a program for which MATH 1342 will fulfill entire math requirement for associate’s degree and for expected bachelor’s degree, if that is relevant.

How did we recruit? Presentation to counselors and advisors, with handouts. Handouts for students “Do you need to take statistics? ” Handouts for students in developmental math classes about pathways through developmental math. Classroom visits in appropriate classes. Email message to students enrolled in Elementary Algebra.

What recruiting worked? The targeted email messages. Of the 70 students who enrolled, more than 55 of them were from the targeted email messages. Some of our faculty / administrators think that more classroom visits might have helped. Definitely we need to get other disciplines to make their needs/preferences about required math courses clearer (Is MATH 1342 acceptable to meet math requirement? ) to help the advisors refer students appropriately.

What course materials do we use? For both semesters: Statway lessons Statway online learning materials (http: //www. mystatway. org/) Our usual MATH 1342 textbook (David Moore’s Basic Practice of Statistics) Statistical software (Crunch-It and Minitab) Some additional materials in developmental math. (We may use this – still considering. )

IMPLEMENTATION STRATEGIES THE IMPORTANCE OF BEING PREPARED AND FLEXIBLE

Weekly Meeting We met at the end of each week for 3 – 5 hours. It seems like a lot, but we found it extremely helpful! Here is what we did that worked: Debrief that week’s lessons Share experiences and strategies Discuss student problems and successes Review student work and progress We gave common exams and similar HW; this made it easier to compare (plus we could share the work of writing the assignments and exams)

Weekly Meeting Discuss next week’s lessons We read these in advance of the meeting if at all possible Head off logistical problems (like when a lesson requires students to “bring a music player”) Anticipate student difficulties in lessons – where we might need to slow down or supplement Readjust Calendar Both instructors and students had to be very flexible! Letting students know ahead of time made them better able to “go with the flow” as we felt our way through the material this first time through

In-semester Adjustments Homework – integrating our text with My. Statway and “Take it Home” assignments o o o Our text definitely has some meaty problems that we wanted student to grapple with. We started slow (one problem from the text mixed with their written lessons and My. Statway work online) One instructor had her students either solve the problem, or write down what questions they would need to have answered to be able to solve the problem We waited to integrate our text until the 4 th week so they had time to get used to all the different avenues of instruction

In-semester Adjustments We each made modifications throughout the semester to the structure of the class periods and the homework assignments. Here are some things I did in my Statway™ class: 10 -minute Introduction • Lets students know what to expect in that day’s lesson 10 -minute Wrap-up • • Reminds students of key ideas that were discovered Doing this as a PPT and posting it online was a nice way to help them organize when they were reviewing for exams

CLASSROOM EXPERIENCES IN THE TRENCHES

Starting the class with the students Week 1 Contracts and expectations Groups Getting to know each other Experiencing the focus on activities What sorts of thoughts / solutions will be counted right? Which ones will be wrong? (These questions require more consideration than you might think, particularly in Module 1. )

Weeks 1 - 3 How to start each part of the course? Activities Group work Software (mystatway. org) Paper homework Which parts will be graded? How many attempts for each checkpoint? When is feedback available? How much is each part relevant to preparing for the test? Which parts will be graded? When is feedback available? How should they think about each part? Using the other textbook Using statistical software

Shift in types of questions Module 1 – Producing Data Activities ask for a lot of “what makes sense? ” on fairly complex questions. At first, how do you say that an answer is wrong – or not fully right – without discouraging students? How do you transition to “produce the correct answer on a test question”? Module 2 – Summarizing data Lots of “thought questions” in activities but also lots of problems to do in homework where it is easy to say what is a wrong answer.

Preparing for a test • What kinds of summaries of important concepts will you provide? o We collected the learning objectives in the lessons in the module. • When – before they start the material, during it, or at the end when giving a test review? o At first we gave it during the test review. We gave them out somewhat earlier after Test 1.

Why we pulled in 12. 1 Module 3 covers regression We thought the students needed to see exact linear models (finding the equation of a line using two points, meaning of slope and intercept) before seeing these in the context of statistical relationships Mixed success o Students didn’t do well on this on the test. o Students did say that it helped them with the Module 3 work on lines.

Computation in the activities In Module 2, for the standard deviation, we didn’t do as much of “square all the deviations and sum them” as the activity called for. That would have taken more time than we had for that lesson. Similarly, in Module 3, the material on SSE and SST was too much. We did talk about the coefficient of determination but shortened the “build-up” to it by informally showing it graphically and then saying that it is algebraically equivalent to r-squared.

Tests The tests from Carnegie are more focused on multiple-choice questions than we have been used to in our statistics courses. The weaker students (in particular) were not good at knowing whether they were prepared for a test with a heavy emphasis on multiple choice questions. We expect to think more about how much we base our test grades on the multiple choice and how much on the free-response questions.

SUCCESS STORIES AND RATES HOW IT’S ALL GOING

What do students think? “First math course where I feel like I understand anything. ” “My favorite college course. No one has ever let me talk about what I’m thinking so much. ” “When I read articles in the newspaper that talk about data, I feel like I know understand what they’re talking about. ” “Quit telling us stuff now. We need to get into our groups and figure it out. ”

And… “I have trouble learning without more practice doing the computations. Will you give me more? ” “You didn’t give us very many practice problems doing the computation. How can you expect that I would do that correctly on the test? ” “I got that multiple choice question wrong because I didn’t read all the choices before I answered it. ”

Success rate so far at ACC Three classes at ACC this fall, with a total enrollment of 70. End of first semester 48 passed out of 54 still enrolled. So far 43 have enrolled (and paid) for the second semester with still about six days of registration left. (We expect all 48 will enroll. ) We are pretty confident that almost all of those left will be able to pass the second course.
