Mathematics is an important discipline, providing crucial tools, such as problem solving, to improve our cognitive abilities. In order to solve a problem, it is better to envision and represent through multiple means. Multiple representations can help a person to redefine a problem with his/her own words in that envisioning process. Dynamic and Interactive Mathematics Learning Environments (DIMLE), allow multiple representations in mathematics and therefore provide opportunities to explore, to explain, and to model (Karadag & McDougall, 2009) mathematical subjects or concepts. The goal of this study is to explore the effect of multiple representations on perceptions of elementary mathematics pre-service teachers in problem solving process. Hence, ten representations, which dynamically represent a word problem, are created by using one of the DIMLE, GeoGebra. The sample group consists of elementary mathematics pre-service teachers (n=17). In order to precisely analyze the data, which are gathered from sample group, quan-qual mix method was used. Consequently, the use of multiple representations, which were prepared by DIMLE, cause to a mental demand for the other mathematical concepts except for understanding and solving a problem.
Today, “Talent Gap” poses as one of the biggest problems in the business world. As the ratio of this talent gap increases, so too does the desperation of businesses to alleviate this problem. This study aims to answer the research problem defined as, “Does using game-based assessment provide an advantage to companies in the war of attracting and retaining young talents?” To answer this, the aptitudes and perspectives of 35 candidates towards the companies in terms of some criteria were measured by means of Analytic Hierarchy Process. In conclusion, this study shows that the companies, offering game based assessment, witnessed a 72 percent more advantageous situation than companies offering traditional assessment tests.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
