Fall 2015 Brown Bag #2 with Dr. Sigmund Tobias and Dr. J. Dexter Fletcher

For our second Brown Bag Presentation of the semester, Eminent Research Professor Dr. Tobias and Dr. Fletcher of the Institute for Defense Analyses led a discussion of their findings related to the use of digital games as a form of educational technology.

According to Dr. Tobias and Dr. Fletcher, as the use of technology has become more popular in educational settings, interest regarding the use of computer games to deliver meaningful instruction has increased.  Digital games can be very useful educational tools if they are used correctly.  Games allow students to interact with the curriculum and instruction.  Students may be more motivated to learn using a game than other forms of instruction.  Games have the ability to give students a sense of self in which they can interact with their technological environment.  Games may also be ideal for students that have learning difficulties, minority students, and students from low SES backgrounds due to the ability of games to tailor games to students' individual differences. Digital games can be used not only in schools, but also in the workplace for instructional development.  It is important to conduct cost analyses, but digital games can cut down on the cost of training and instructional development,

Games must be educational in order to be useful for an instructional purpose.  Digital game creators need to focus on what students will be learning from the game not just the technology behind the game.  In order for games to be useful and effective, they need to be highly integrated with the curriculum.

Fall 2015 Brown Bag #1 with Dr. Mariola Moeyaert

Dr. Mariola Moeyaert presented our first Brown Bag discussion of the semester.  Dr. Moeyaert discussed the topic of "Multilevel Meta-Analysis of Single-Case Effect Size Estimators: General Introduction and Application".

This is Dr. Moeyaert's first year teaching at UAlbany.  She is teaching Statistics 1 this Fall and will be teaching Statistics 2 and Single-Case Experimental Design in the Spring of 2016.  Dr. Moeyaert received her Ph.D. in Educational Statistics at the Methodology of Educational Sciences Research Group, KU Leuven, Belgium.  

Dr. Moeyaert has been researching how the three-level meta-analytic model can be used to combine data from single-subject experimental designs and estimate effect size.  The findings can be used to evaluate and improve interventions in addition to influencing future single-subject experimental design research. 

The multi-level analysis of single-case experimental data consists of three main parts: single-case experimental designs, multilevel modeling, and meta-analysis.  Single-case experimental designs are used to collect data for a single individual over time.  The collected data are used to determine if an intervention is having an impact on an individual's performance on what is being measured.  A multilevel modeling approach allows researchers to look at the effect sizes within cases, across multiple cases, and across multiple studies. Meta-analysis is then used to determine if interventions are useful and successful.  Dr. Moeyaert's research has concluded that a multilevel modeling framework successfully estimates the effect within cases, across cases, and across studies.
