Implementing Elements of The Physics Suite at a Large Metropolitan Research University
A key question in physics education is the effectiveness of the teaching
methods. A curriculum that has been investigated at the University of Central
Florida (UCF) over a period of two years is the use of particular elements of
The Physics Suite. Select sections of the introductory physics classes at UCF
have made use of Interactive Lecture Demonstrations as part of the lecture
component of the class. The lab component of the class has implemented the
RealTime Physics curriculum, again in select sections. The remaining sections
have continued with the teaching methods traditionally used. Using pre- and
post-semester concept inventory tests, a student survey, student interviews,
and a standard for successful completion of the course, the data indicates
improved student learning

Practitioner Track Proceedings of the 6th International Learning Analytics & Knowledge Conference (LAK16)
Practitioners spearhead a significant portion of learning analytics, relying on implementation and experimentation rather than on traditional academic research. Both approaches help to improve the state of the art. The LAK conference has created a practitioner track for submissions, which first ran in 2015 as an alternative to the researcher track.
The primary goal of the practitioner track is to share thoughts and findings that stem from learning analytics project implementations. While both large and small implementations are considered, all practitioner track submissions are required to relate to initiatives that are designed for large-scale and/or long-term use (as opposed to research-focused initiatives). Other guidelines include:
ā¢ Implementation track record The project should have been used by an institution or have been deployed on a learning site. There are no hard guidelines about user numbers or how long the project has been running.
ā¢ Learning/education related Submissions have to describe work that addresses learning/academic analytics, either at an educational institution or in an area (such as corporate training, health care or informal learning) where the goal is to improve the learning environment or learning outcomes.
ā¢ Institutional involvement Neither submissions nor presentations have to include a named person from an academic institution. However, all submissions have to include information collected from people who have used the tool or initiative in a learning environment (such as faculty, students, administrators and trainees).
ā¢ No sales pitches While submissions from commercial suppliers are welcome; reviewers do not accept overt (or covert) sales pitches. Reviewers look for evidence that a presentation will take into account challenges faced, problems that have arisen, and/or user feedback that needs to be addressed.
Submissions are limited to 1,200 words, including an abstract, a summary of deployment with end users, and a full description. Most papers in the proceedings are therefore short, and often informal, although some authors chose to extend their papers once they had been accepted.
Papers accepted in 2016 fell into two categories.
ā¢ Practitioner Presentations Presentation sessions are designed to focus on deployment of a single learning analytics tool or initiative.
ā¢ Technology Showcase The Technology Showcase event enables practitioners to demonstrate new and emerging learning analytics technologies that they are piloting or deploying.

SizeNet: Weakly Supervised Learning of Visual Size and Fit in Fashion Images
Finding clothes that fit is a hot topic in the e-commerce fashion industry.
Most approaches addressing this problem are based on statistical methods
relying on historical data of articles purchased and returned to the store.
Such approaches suffer from the cold start problem for the thousands of
articles appearing on the shopping platforms every day, for which no prior
purchase history is available. We propose to employ visual data to infer size
and fit characteristics of fashion articles. We introduce SizeNet, a
weakly-supervised teacher-student training framework that leverages the power
of statistical models combined with the rich visual information from article
images to learn visual cues for size and fit characteristics, capable of
tackling the challenging cold start problem. Detailed experiments are performed
on thousands of textile garments, including dresses, trousers, knitwear, tops,
etc. from hundreds of different brands.Comment: IEEE Conference on Computer Vision and Pattern Recognition Workshop

Semi-Supervised Self-Taught Deep Learning for Finger Bones Segmentation
Segmentation stands at the forefront of many high-level vision tasks. In this
study, we focus on segmenting finger bones within a newly introduced
semi-supervised self-taught deep learning framework which consists of a student
network and a stand-alone teacher module. The whole system is boosted in a
life-long learning manner wherein each step the teacher module provides a
refinement for the student network to learn with newly unlabeled data.
Experimental results demonstrate the superiority of the proposed method over
conventional supervised deep learning methods.Comment: IEEE BHI 2019 accepte

Zero Shot Learning for Code Education: Rubric Sampling with Deep Learning Inference
In modern computer science education, massive open online courses (MOOCs) log
thousands of hours of data about how students solve coding challenges. Being so
rich in data, these platforms have garnered the interest of the machine
learning community, with many new algorithms attempting to autonomously provide
feedback to help future students learn. But what about those first hundred
thousand students? In most educational contexts (i.e. classrooms), assignments
do not have enough historical data for supervised learning. In this paper, we
introduce a human-in-the-loop "rubric sampling" approach to tackle the "zero
shot" feedback challenge. We are able to provide autonomous feedback for the
first students working on an introductory programming assignment with accuracy
that substantially outperforms data-hungry algorithms and approaches human
level fidelity. Rubric sampling requires minimal teacher effort, can associate
feedback with specific parts of a student's solution and can articulate a
student's misconceptions in the language of the instructor. Deep learning
inference enables rubric sampling to further improve as more assignment
specific student data is acquired. We demonstrate our results on a novel
dataset from Code.org, the world's largest programming education platform.Comment: To appear at AAAI 2019; 9 page
Science Teacher Learning of MBL-Supported Student-Centered Science Education in the Context of Secondary Education in Tanzania
Science teachers from secondary schools in Tanzania were offered an in-service arrangement to prepare them for the integration of technology in a student-centered approach to science teaching. The in-service arrangement consisted of workshops in which educative curriculum materials were used to prepare teachers for student-centered education and for the use and application of Microcomputer Based Laboratories (MBL)āa specific technology application for facilitating experiments in science education. Quantitative and qualitative data were collected to study whether the in-service arrangement impacted teacher learning. Teacher learning was determined by three indicators: (1) the ability to conduct MBL-supported student centered science lessons, (2) teachersā reflection on those lessons and (3) studentsā perceptions of the classroom environment. The results of the research indicate that the teachersā were able to integrate MBL in their science lessons at an acceptable level and that they were able to create a classroom environment which was appreciated by their students as more investigative and open-ended
