What is Chickscope?What is Chickscope?(http://chickscope.beckman.uiuc.edu/)(http://chickscope.beckman.uiuc.edu/)
• Chickscope is a project to study chicken embryo development using a variety of educational resources, such as inquiry-based curriculum materials, interactive modules on egg mathematics, image processing, and remotely controlled magnetic resonance imaging instrument.
• It is being developed by educators and researchers from several UIUC departments in collaboration with inservice and preservice teachers, and the Image Processing for Teaching project at the University of Arizona.
• Inquiry-based materials by collaborating teachers are at http://www.ed.uiuc.edu/inquiry/.• Chickscope overview for parents and teachers is at
http://chickscope.beckman.uiuc.edu/about/overview/.

Remote scientific instrumentationRemote scientific instrumentation
• Using a standard Web browser, researchers, teachers, or students in any location and at any time have the potential to access the latest scientific instruments without having to travel to a remote site or invest in the hardware themselves.
• Accordingly, the Web becomes a laboratory for many fields of research and education—a World Wide Laboratory (WWL).
• Chickscope is a working example of the WWL project.• In addition to Chickscope, there are other innovative scientific instrumentation
projects on the Web (e.g., Stardial, an autonomous astronomical camera).

Participants in the first Chickscope projectParticipants in the first Chickscope project
• The ten participating classrooms during the spring of 1996 ranged from kindergarten to high school, including an after-school science club and an out-of-state home school.
• In all, there were 210 students, 9 teachers, and 15 undergraduate students in the classrooms.
• Teachers selected based on their school or classroom access to the Internet, interest in the project, and plans for integrating it into their curriculum.
• Teacher training prior to and during the project.• A Sample Scenario: Primary School Classroom

• Six to eight primary students per group for image acquisitions.• “Look at quadrant F3. We are looking at the top [view]. What do
you think we could do next? What do you think the white spots are?” [Teacher leading a discussion in the classroom]
• “The bright spots above and below it [heart area] are signals from the blood in the ventricle. These spots are in the wrong places because they are moving too rapidly.” [Expert observations and annotations]

Impact in classroomsImpact in classrooms (http://www.ed.uiuc.edu/facstaff/chip/Publications/chickscope/)(http://www.ed.uiuc.edu/facstaff/chip/Publications/chickscope/)
• Situated evaluation approach to examine how Chickscope is used across different classroom contexts.
• General questions to guide our understanding of the project– How useful is MR imaging (with and without remote access)
for understanding chick embryo development?– What different modalities are available to students?– What are students learning from this experience?– What kinds of support structure is provided to teachers?– What are some of the unexpected events?
University of Illinois at Urbana-Champaign
Situated evaluation of educational innovationsSituated evaluation of educational innovations
• Situated evaluation is focused on the innovation-in-use across contexts (Bruce and Rubin, 1993).
• Some of the purposes of situated evaluation include:– explain why the innovation was used the way it was– predict the results of using the innovation– identify similarities and differences across settings– improve the use of the innovation– improve the technology– identify variables for later evaluation
University of Illinois at Urbana-Champaign
Situated evaluation processSituated evaluation process
• The situated evaluation process has three key aspects:– understand the idealization of the innovation– examine the settings in which the innovation appears– analyze the realizations of the innovation
• The guiding assumption in the process is that the innovation comes into being through use.

Lessons learnedLessons learned
• Students working in groups were able to share computers and limited MRI time effectively to do serious science for an extended period.
• Students more involved in Chickscope when it was integrated into the classroom curriculum plans.
• In spite of the complexity of the technology, students and teachers across K-12 were able to benefit.
University of Illinois at Urbana-Champaign
Diverse range of benefitsDiverse range of benefits
• Exposure to a new way of using the Internet.• Increased understanding of the process of gathering scientific
data.• Opportunity to interact with scientists from several disciplines.• Motivation for learning science and sustained interest in the
scientific enterprise (i.e., at least 21 days).• Continuing sustained use of resulting project materials by
classrooms that did not originally participate or have access to the remote instrumentation.
University of Illinois at Urbana-Champaign
Implications for K-12 outreach from the first Implications for K-12 outreach from the first Chickscope projectChickscope project
• Access to new technologies should be possible through standard computer hardware and software, such as Web browsers.
• Online interactions with experts is essential for doing scientific investigations, especially for students in the lower grades who may need specific guidance as well as immediate feedback.
University of Illinois at Urbana-Champaign
Why Illinois Chickscope?Why Illinois Chickscope?
• The first Chickscope project was successful in immersing students and teachers in a small scientific community. Students and teachers learned much about how to collect and analyze data, how to ask questions, and how to communicate their findings with others (Bruce et al, 1997).
• Planned to scale this project up to provide further opportunities to students and teachers at state and national levels.
• Proposed a professional development program, now referred to as Illinois Chickscope (ILCS), for K-12 teachers during the spring, summer, and fall semesters of 1998 (Bruce and Thakkar, 1997; Potter, 1997).
• ILCS was initially proposed as Champaign County Chickscope (CCC) before teachers from east-central Illinois got involved.

• Illinois Chickscope is building a community of teachers; linking that community with scientists in a variety of disciplines; promoting an integrated understanding in science and mathematics; and teaching new ways of using the Internet.
• ILCS participants are 32 K-12 teachers (21 elementary school teachers, 4 middle school teachers, and 7 high school teachers) from 15 schools in Champaign County and Charleston-Mattoon area.
• ILCS started by introducing Chickscope to 57 preservice teachers in fall of 1997 so that these teachers can take their new pedagogical knowledge into their student teaching, including in the classrooms of the ILCS teachers.
University of Illinois at Urbana-Champaign
ILCS objectivesILCS objectives
ILCS objectives include:• To demonstrate what is required to scale up a successful local
project to a larger community.• To build collaborations between teachers, preservice teachers, and
scientists in order to promote and facilitate scientific investigations using the Internet.
• To test the information infrastructure by providing a diverse range of classrooms with access to the interactive MRI database.
• To assess the effectiveness of Illinois Chickscope in motivating and preparing teachers for incorporating inquiry-based learning and teaching in science and mathematics classrooms.
University of Illinois at Urbana-Champaign
ILCS inservice scheduleILCS inservice schedule
ILCS teachers are expected to attend 11 inservice days. Eachday includes interactive discussions, hands-on, and computer-based activities related to chick embryology and MR imaging.• During the spring semester, the teachers were learning about
Chickscope through five inservice days.• During a week-long summer inservice, the teachers focussed
on developing inquiry-based curriculum materials for use in their classrooms.
• During the fall semester the teachers will return for one day of inservice, where they will introduce the ILCS project to new preservice teachers and other interested teachers.
University of Illinois at Urbana-Champaign
Inquiry themes Inquiry themes
Inquiry themes during inservice focus on a broad question: How do we build a community for inquiry learning?• How do we get students to engage in inquiry?• How do we ensure that all students are involved in inquiry
activities?• How do teachers link to other teachers and student teachers to
facilitate inquiry learning and teaching?• What are the roles for scientists in supporting inquiry in the
classroom?• How can teachers study their own inquiry practice and share
what they learn with others?
University of Illinois at Urbana-Champaign
ILCS evaluation proceduresILCS evaluation procedures
• ILCS evaluation questions will focus on the project objectives. For instance, what is required to scale up? Is collaboration among classroom teachers, preservice teachers, and scientists supported? How well does the information infrastructure work? Are teachers supported in inquiry-based teaching?
• A formative evaluation is being conducted to guide the project development.
• A summative evaluation during the summer and fall semesters will assess the overall impact of the project.
• A variety of data is being collected for evaluation. Appropriate consent from teachers, preservice teachers, school, and university has been obtained before the start of the project.
University of Illinois at Urbana-Champaign
ILCS and scientific instrumentation?ILCS and scientific instrumentation?
• The goal for the Chickscope project was not only to provide students and teachers with access to the MRI instrument, but also to provide them with the supporting infrastructure that is usually reserved for scientists.
• It is difficult to sustain the infrastructure of both the people and the underlying technology for a long duration.
• ILCS teachers (and their students) will be using images from the MRI database to learn about embryonic development and growth; for instance, studying the change in the yolk occurring between 24 to 72 hours of development (see, for example, http://chickscope.beckman.uiuc.edu/explore/biological_imaging).
• The database includes MR images acquired by students during the first Chickscope project.

Significance in educationSignificance in education
• Remote scientific instrumentation is part of the daily practice in research and industry (e.g., Mars Pathfinder mission).
• Students at all levels may need to learn more about this new technology for doing science, and that it is likely to be less costly in the future (e.g., electronic mail).
• The particular instruments and scientific domains may change, but understanding the principles underlying this mode of learning through projects like Chickscope should be generalizable to other domains, such as cell biology, involving new technologies, such as transmission electron microscope.
University of Illinois at Urbana-Champaign
Current directionsCurrent directions
• I am working on a review of scientific instrumentation projects in many domains, such as radio astronomy, cell biology, and nanomaterials.
• My interest is in evaluation of WWL technologies to understand their impact in research and education; for instance,– What effect WWL technologies have on student learning?– How WWL technologies support scientific collaboration and
expand participation in science?
