EDM'14 - Choice-based assessment:

Submitted by Sharon Hsiao on Sat, 07/05/2014 - 6:51am.

Another fascinating paper:
Can Choices Made in Digital Games Predict 6th-Grade Students' Math Test Scores?

In this paper, we mined students' sequential behaviors from an instructional game for color mixing called Lightlet. Students pkaying the game have two broad strategies. They can either test candidate color combinations in an experiment room without risking an incorrect answer. Or they can choose colors from a faux shopping Catalog containing several different mixing charts. While the results shown in the Experiment Room are always correct, only a few of the charts in the Catalog are correct. Thus, if students use the catalog students must apply critical thinking skills to determine what charts to trust. Our primary goal in this work was to identify the crucial choice pattern(s) in students' game play that would contribute to their learning or subsequent performance.

Who’s in Control?: Categorizing Nuanced Patterns of Behaviors within a Game-Based Intelligent Tutoring System

The authors use dynamical analyses to investigate the relation between students’ patterns of interactions with various types of game-based features and their daily performance. High school students (n=40) interacted with a game-based intelligent tutoring system across eight sessions. Hurst exponents were calculated based on students’ choice of interactions with four types of game- based features: generative practice, identification mini-games, personalizable features, and achievement screens. These exponents indicate the extent to which students’ interaction patterns with game-based features are random or deterministic (i.e., controlled). Results revealed a positive relation between deterministic behavior patterns and daily performance measures. Further analyses indicated that students’ propensity to interact in a controlled manner varied as a function of their commitment to learning. Overall, these results provide insight into the potential relations between students’ pattern of choices, individual differences in learning commitment, and daily performance in a learning environment.

EDm'14 - A Data-Driven Approach: Learning Individual Behavior in an Educational Game

Submitted by Sharon Hsiao on Sat, 07/05/2014 - 5:58am.



Modeling and predicting individual behavior in such interactive environments is crucial to better understand the learning process and improve the tools in the future. A model-based approach is a standard way to learn student behavior in highly-structured systems such as intelligent tutors. Defining such a model relies on expert domain knowledge.

They propose a data-driven approach to learn individual behavior given a user’s interaction history. This model does not heavily rely on expert domain knowledge. They use framework to predict player movements in two educational puzzle games, demonstrating that our behavior model performs significantly better than a baseline on both games. This indicates that our framework can generalize without requiring extensive expert knowledge specific to each domain.

EDM'14 - Keynote: The field of EDM: Where We Came From and Where We're Going

By Dr. Joe Beck

Abstract: The Educational Data Mining community has undergone tremendous growth in the past decade. This talk will discuss how we got to where we are, as well as upcoming challenges for the field. The beginning of the EDM workshop series grew out of the AIED and ITS conferences, which greatly influenced both the initial participants and the frameworks used for viewing data mining problems. The development of the EDM conference series served to focus the field, and greatly increase the range of participants. Although much progress has been made in the past 6 years, there remain some large challenges not (yet) well addressed by the EDM community. Two issues include who are the consumers for the advances that we make, and under what conditions can we draw scientific conclusions from data-mining activities.

Biography: Joseph has a PhD in computer science. His research focuses on educational data mining, a new discipline that develops techniques for analyzing large educational data sets to make discoveries that will improve teaching and learning. His work centers on estimating how computer tutors impact learning. He established the first workshop in the field and in 2008 was program co-chair of the first EDM.

What is Biomedical Engineering?

Submitted by Kafoumba Doumbia on Thu, 07/03/2014 - 11:41pm.

Biomedical engineering is an engineering discipline that focuses on the medical and healthcare aspects of technology. Biomedical engineers do research and develop product and engineering devices that help patients and people with disabilities. This engineering discipline might sound complicated because it does not involve engineering principles and designs but rather medical aspects such as biology and other natural sciences. It is an interesting field of study because you get to make artificial legs, arms and other human body parts to make lives better. Technology does more jobs in the hospitals than doctors because those developed by biomedical engineers make their work easier and help them get better results. Technology and engineering runs everything I do, therefore we should encourage and provide the necessary knowledge to our students in order to better prepare them to become future engineers, doctors and technologists.

Helping Students

Submitted by Oumar Soumahoro on Thu, 07/03/2014 - 12:29am.

It is often said that education is the key to success. In other words, one is most likely to become successful if they are well educated. However, with tuition and student loans at an alarming high rate, a lot of students are missing out on education and ultimately success. I’ve noticed witnessed that students with financial hardship find it impossible to complete their assignments when facilities are not open or when they are fully occupied. However, this following article shares efficient ways to help students stay in school and on top of their education.

The Joy of Music

Submitted by Youssef Ballo on Wed, 07/02/2014 - 11:50pm.

Music can be learned in a variety of ways. For some, it is a natural gift while others spend countless hours practicing and honing their skills. Now, anyone can learn music through gaming. Joy Tunes is a web and mobile application that allow individuals to learn to play real instruments. Joy Tunes was established in 2010 by a private Israeli company and developed by experienced musical artists and educators. The games are intended to teach and encourage people to practice by changing music exercises into fun games. Joy Tunes is also a great platform for aspiring producers and composers to mix and match music.

Why don’t the highly educated smoke?

Submitted by Sarpong Adjei on Wed, 07/02/2014 - 10:58pm.

A recent study by researchers at Yale University sough to look at some of the reasons why Americans with less education tended to smoke more than those well educated. The study, relying on data collected over a 14-year span, concluded that adults with college degrees were less likely to smoke than those without. The study argues that by age 12, the link between smoking and eventual educational levels will begin to appear.

In my opinion, I believe that education does play a role in smoking at adulthood. My theory is that it is stresses of education such as excelling, being at the top of your game and many other factors that lead to smoking. Many adults result to smoking as a source to relieve stress. While that may provide a momentary relief, the long-term effects could be life threatening.

Motivation Among Young Athletes

Submitted by Malik Muftau on Wed, 07/02/2014 - 6:57pm.

There is an adage that young athletes with exceptional talents are not motivated to play to the best of their abilities. As a result, coaches have a huge task of ensuring their players are motivated and dedicated to putting in their best performances every game. This article explores the role of coaches in ensuring that their players are motivated enough in order to attain positive results. For instance, coaches are encouraged to use effective communication skills to help their athletes motivate themselves.

Interestingly, this article broadens its scope because it does not only focus on motivation in sports. The article also gives several tips to teachers on how they can motivate their students. Motivation forms an integral part of everyday life and often determines successes and failures. I am however convinced that the greatest motivator is you. When we are motivated, we work extra hard towards a specific goal.
