Fall 2011 Student Response System Pilot

Summary Report

NDSU has been standardized on a single student response (i.e., “clicker”) system for over a decade, with the intent to provide a reliable system for students and faculty that can be effectively and efficiently supported by ITS. In April 2011, Instructional Services made the decision to explore other response options and to identify a suitable replacement product for the previously used e-Instruction Personal Response System (PRS). At the time, PRS was laden with technical problems that rendered the system ineffective and unsupportable. That system also had a steep learning curve, was difficult to navigate, and was unnecessarily time-consuming to use. In fact, many universities across the U.S. experienced similar problems with PRS and have since then adopted alternative systems.

A pilot to explore alternative response systems was initiated at NDSU in fall 2011. The pilot was aimed at further investigating two systems—Turning Technologies and iClicker—in realistic classroom environments. As part of this pilot program, each company agreed to supply required hardware and software at no cost to faculty or students. Each vendor also visited campus to demonstrate their product to faculty, students and staff.

An open invitation to participate in the pilot was extended to all NDSU faculty on a first come, first serve basis. Of those who indicated interest, 12 were included as participants in this pilot.

Pilot Faculty Participants:

• Angela Hodgson (Biological Sciences)
• Ed Deckard (AES Plant Science)
• Mary Wright (Nursing)
• Larry Peterson (History, Philosophy & Religious Studies)
• Ronald Degges (Statistics)
• Julia Bowsher (Biological Sciences)
• Sanku Mallik (Pharmaceutical Sciences)
• Adnan Akyuz (AES School of Natural Resource Sciences)
• Lonnie Hass (Mathematics)
• Nancy Lilleberg (ITS/Communications)
• Lisa Montplaisir (Biological Sciences)
• Lioudmila Kryjevskaia (Physics)

Pilot Overview

The pilot included three components: 1) Vendor demonstrations, 2) in-class testing of the two systems, and 3) side-by-side faculty demonstrations of the two systems.

After exploring several systems, Instructional Services narrowed down to two viable options—Turning Technologies and iClicker. Both of these systems met initial criteria that was assembled based on faculty input and previous usage of the existing response system. These criteria included durability, reliability, ease of use, radio frequency transmission, integration with Blackboard LMS, cross-platform compatibility (Mac, PC), stand-alone software (i.e., no longer tied to PowerPoint or other programs), multiple answer formats (including multiple choice, true/false, numeric), potential to migrate to mobile/Web solutions at some point in the future, and cost to students and the university.

In the first stage of the pilot, both vendors were invited to campus to demonstrate their respective technologies. These presentations took place during spring semester 2011 and were attended by faculty, staff and students. The purpose of these presentations was to introduce both systems and provide faculty, staff, and students with an opportunity to take a more hands-on look at the systems and provide their initial feedback.

In the second stage of the pilot, faculty were invited to test the technologies in their classes during fall semester 2011. Both vendors supplied required hardware and software at no cost to faculty and students, and both provided online training to orient faculty to their respective system. Additionally, Instructional Services staff provided follow-up support and training throughout the pilot program. Both vendors were requested to ensure system integration with Blackboard. Both vendors indicated that they would provide the number of clickers necessary to test the systems equally across campus. Both clickers were allocated to courses of varying sizes, ranging from 9 to 400+ students, to test viability in various facilities with differing numbers of users. Participating faculty agreed to offer personal feedback and collect feedback from students regarding experiences with the systems at the end of the pilot.

In the final stage of the pilot, Instructional Services facilitated a side-by-side demonstration led by two faculty members. Each faculty member showcased each product on a function-by-function basis so that attendees were able to easily compare and contrast the two systems. Feedback was collected from attendees.

Results of Pilot

In stage one, we established that both systems were viable and appeared to offer similar features, functions, and were compatible with existing IT systems at NDSU. The determination was made to include both products in a larger classroom trial.

In stage two, we discovered that both systems largely functioned as intended; however, several differences between the technologies in terms of advantages and disadvantages were discovered that influenced our final recommendation. (See Appendix A for a list of these advantages, disadvantages, and potential workarounds.) We also encountered two significant issues that altered the course of the pilot. Initially, it was intended that both systems would be tested in equal number in terms of courses and students. Unfortunately, at the time of the pilot, iClicker was not able to provide more than 675 clickers, which was far fewer than anticipated. Turning Technologies was able to provide 1,395 clickers. As a result, Turning Technologies was used by a larger number of faculty and students across campus.

At the beginning of the pilot, Blackboard integration with iClicker at NDSU was not functional. The iClicker vendor provided troubleshooting assistance immediately, but the problem was not resolved until mid-November. As a result, iClicker users had to use alternative solutions for registering clickers and uploading points to Blackboard for student viewing. Turning Technologies was functional and fully integrated with Blackboard throughout the pilot.

During the span of the pilot additional minor issues were discovered with both systems. A faulty iClicker receiver slightly delayed the effective start date of clicker use in one course.  The vendor responded by sending a new receiver, however it was an incorrect model. Instructional Services temporarily exchanged receivers with another member of the pilot group until a functional replacement arrived. Similarly, a Turning Technologies receiver was received with outdated firmware. Turning Technologies support staff identified the problem and assisted in updating the firmware with an update tool located on their website. A faculty participant discovered a software flaw in the iClicker software that hides the software toolbar when disconnecting a laptop from a second monitor. iClicker technical support assisted in identifying the problem and stated the problem would be addressed in a future software update. A workaround was identified that mitigated this problem for the remainder of the pilot. It is important to note that these issues were not widespread and did not widely affect all pilot users, however these issues attest to the need for timely, reliable, and effective vendor support.

Students and faculty reported positive experiences with both technologies throughout the semester. Based on feedback, users of both systems found the new technologies to be much improved over the previous PRS system, indicating that adopting either technology would be perceived as an upgrade among students and faculty. Faculty pilot testers met several times during the semester to discuss their experiences with each system; feedback was sent to each vendor for their comments, suggestions, and solutions.

During the stage three demonstrations, feedback from attendees focused on the inability for iClicker to integrate with Blackboard at that time and the substantial differences between the two systems in terms of entering numeric values (i.e., Turning Technologies has numeric buttons, while iClicker requires the use of a directional key pad to scroll through numeric characters). Feedback indicated that attendees perceived Turning Technologies’ clickers to be much more efficient for submitting numeric responses. Feedback regarding other functionalities indicated relative equality between both systems.

Recommendation

Based on the findings of this pilot, Instructional Services recommends that NDSU IT adopt Turning Technologies as the replacement for the existing PRS system. While both pilot-tested systems are viable solutions, Turning Technologies appears to meet the needs of a larger user base. Additionally, the support offered by Turning Technologies was more timely and effective throughout the pilot. With the limited resources of IT, vendor support is critical and was a major reason for exploring alternative student response technologies.

From Instructional Services’ standpoint, standardizing to one solution is imperative for two major reasons: cost efficiency for students (i.e., preventing students from having to purchase duplicate technologies) and efficient utilization of IT resources (i.e., support and training). It is important to note that this recommendation is based on the opinion of the Instructional Services staff and the majority of pilot testers, but is not based on consensus among all participating faculty and staff. It is possible that individual faculty members may elect to use other options that best meet their individual teaching needs, including (but not limited to) iClicker. As an IT organization, we continue to support technology that serves faculty, student and staff needs across various colleges, disciplines, and courses. We feel that this pilot was effective in determining the student response technology—Turning Technologies—that will best serve NDSU faculty, students and staff for the foreseeable future.

Once a final decision concerning standardization is made, contract negotiations should begin in earnest with the goal of completion by January 1, 2012, in order to accommodate those wishing to use clickers during the spring session.

Appendix A: Clicker Comparisons
Turning Technologies and iClicker

Areas where both products have comparable functionality:

• Setting up the receiver and software
• Student registration of clickers
• Software interface floats above other software
  • Can use with anything – PowerPoint, Websites, Word, etc.
  • Asking questions on the fly
  • Can create questions / answers files
  • Managing scores and data
    • Allow participation points, points for correct answer, change correct answer
    • Reporting – Summary and Detailed
    • Uploading scores and data to Blackboard (but there was a big delay with the iClicker product)
    • Durability of the receivers and clickers
    • Free software
    • Offer mobile web device product to go “clickerless”

Areas where the products differ:

Main Shortcomings of Turning Technology Product:

• Costs $5 more – no workaround
• Doesn’t have instructor readout window on receiver base –
  • This is a handy function in iClicker that lets the instructor see the %’s of votes as they come in, allowing the instructor to plan how he/she will proceed.
  • Workaround: As the time winds down to answer the question, the question and answers are displayed on the screen. Intermittently, the instructor would push a button to mute the projector, push a button to view graph results quickly, then push a button to hide graph and push a button to unmute the projector. In summary, push four buttons quickly each time you want to see the feedback, and the students will see a black screen momentarily.
  • Processing multiple sessions when uploading grading –
    • Turning Technologies uses their own file structure types, but iClicker uses comma-separated-value text files which work easily with Excel
    • Workaround: When uploading grades into Blackboard, upload them one session at a time, and use a calculated total column in Bb to combine them. Ideally, instructors would upload the grades daily or weekly to avoid backlog of sessions.

Main Shortcomings of iClicker Product:

• Entering numeric answers –
  • Questions that use numeric answers are widely used in Math and the sciences. Instead of choosing a multiple-choice answer, students solve the problem and enter the actual numeric answer, which can include numbers and symbols.
  • Workaround: Students push mode button and use directional pad to scroll up and down through a list of numbers, letters and symbols to choose each character individually from left to right. Then they must submit the answer.
  • Number of multiple choice answers –
    • iClicker has 5 buttons on the transmitter for direct answer choices and Turning Technologies has 10.
    • Workaround: Similar to numeric answer workaround. Once again the simpler transmitter becomes complex for the students.
    • Potential Vendor Support Problems –
      • It took iClicker over 3 months to get their grade upload interface working with NDSU’s Blackboard system. The Turning Technology interface worked right away.  No workaround.
