2. Agenda
• Millennials!
• Our NSF Grant
• UCS and Learning Preferences
• What We Have Done and Are Doing
• In the Future….
• Implications for Higher Education
• The Tool!
3. Millennials
• Multitask
• Have Short Attention
Spans
• Tend to be Visual
Learners
• Bore Easily
• Want Instant
Gratification
• Want Control Over
Their Learning
• Have an Expectation
to Achieve
• Lack Self-Reflection
Skills
• Need Individualized
Educational
Opportunities
4. Our NSF Grant - iSECURE
•Ultimate Course Search (UCS)
• Use all digital Material
• Textbook
• Articles, PowerPoint Presentations,
etc.
• Lecture Videos
• Create Searches
• Integrate Learning Preferences
5. iSECURE
• Multimedia data often relies on annotation
However, manual annotation is tedious
• How to effectively and efficiently search such a
huge amount of heterogeneous data?
6. Multimedia Retrieval Problem
• Given a query (either image or video), retrieve
relevant items from a (large) set of multimedia files
7. Image/Video Representation
• Each keypoint descriptor is in high dimensional space
• Each image/keyframe is represented as a sparse set of
points, each point in high dimensional space
• Search: matching between two images will take
considerable time!!

9. Powerpoint Presentation
Indexing and Search
• Indexing
• Stemmed text is indexed with their name, value
pairs(slidenumber, slidetitle, slidetext)
• The set of slides belonging to a presentation file are mapped
relationally to that presentation along with the values of
presentation title and presentation filename
• The keywords will be stored as an inverted index (Given a
keyword, the set of slides(and presentations) in which the
keyword is found is mapped as an inverted listing)
• Search
• The presentations(slides in actual) are searched for matches in
keywords
• A presentation’s relevancy is calculated by the following :
• The score of each slide that belong to the same presentation is summed up
• The presentations are ranked according to their total score of relevancy
(higher to lower)
10. Lecture Video
• In order to find where the slide exists in a video, we need
to segment the lecture video
• We determine the transition of videos that are currently
recorded using a software
• For the videos recorded prior, we can use image
processing techniques to get the transition
• Once transition is found we can easily determine the
duration of the slide segment of video
11. Textbook
• We use the textbook back index and the ontology to form
our index
• The book’s index words and page numbers of the word’s
occurrences are organized as the following XML
<Textbook title = ‘textbookTitle’ >
<Keyword>
<Word> index word </Word>
<PageNumber>1,2,3 </PageNumber>
<Keyword>
</Textbook>
• The above information is indexed using Apache Lucene
12. Our Objectives for UCS
• Create a program that will accurately
search all electronic course materials
• Integrate UCS into Courses
• Help students understand learning
preferences as connected to UCS
• Create a user friendly, clean interface
• Determine the effectiveness of the tool
13. The Research
• Developed the Ultimate Course Search
Tool – Beta
• Begun Collecting Data in a Security Course
• Control and Experimental
• Demographics, Pre-Post Test, ILS
14. Learning Preferences
• Index of Learning Preferences (Felder &
Soloman, 1993)
Four Types of Learners
• Active – Reflective
• Sensing – Intuitive
• Visual – Verbal
• Sequential - Global
17. Student Demographics
Control
• N = 28
• Mean Age = 23.8
• Year in School = 3.54
• Gender
• Female = 4
• Male = 24
• Racial/Ethnic Identifiers
• African American/Black = 5
• American Indian or Alaska = 0
• Asian = 3
• Caucasian/White = 12
• Hispanic/Latino = 9
• Pacific Isl/Native Hawiian = 1
• Other = 4
• No Answer = 3
Experimental
• N = 21
• Mean Age = 23.19
• Year in School = 3.52
• Gender
• Female = 1
• Male = 20
• Racial/Ethnic Identifiers
• African American/Black = 2
• American Indian or Alaska = 1
• Asian = 6
• Caucasian/White = 6
• Hispanic/Latino = 8
• Pacific Isl/Native Hawiian = 1
• Other = 5
• No Answer = 0
18. Survey Feedback: How did the
students using UCS?
• Search for Information/specific words & terms
• Review video podcast lectures
• As a reference
• To study for the Midterm and Final
• To help complete class projects
19. Survey Feedback: What did the
students like about UCS?
• User friendly
• Search engine
• Fast and accurate
• Search exact words
• Tabs and specific information
• Search Videos
• Searches lead to a lot of information
• Helped Students Understand Concepts
• Made studying easier
• Able to better understand material covered in class
20. Pre and Post Test Results
Control
• Pre Test Mean = 9.39
• Standard Dev = 2.25
• Post Test Mean = 12.13
• Standard Dev = 2.29
• Change in Scores = 2.74
Experimental
• Pre Test Mean = 9.10
• Standard Dev = 2.16
• Post Test Mean = 11.70
• Standard Dev = 3.09
• Change in Scores = 2.60
21. Implications for Higher Education
• Reduce attrition
• Increase clarity of course organization
• Increase student interaction with materials
• Individualize learning
• Create connections within and between courses
22. In the Future….
• In the Fall – integrate into Hybrid Graduate
Counseling course and MSU Computer Science
Course
• UCS will have individual learning preferences
assessment and information accessible in-tool
• UCS will be integrated into a course
management system – like Moodle or Canvas
23. In the Future….
• UCS will Learn from the Students – and Provide
Search Terms in Preferential Order Based on
Learning Preferences and Previous Viewings of
Material
• UCS will be linked to a database of courses
• More buttons! UCS will have the ability to add
more types of materials – with more buttons
