Effectiveness of virtual reality-based instruction on students' learning outcomes in K-12 and higher education

Abstract: The purpose of this meta-analysis is to examine overall effect as well as the impact of selected instructional design principles in the context of virtual reality technology-based instruction (i.e. games, simulation, virtual worlds) in K-12 or higher education settings. A total of 13 studies (N?=?3081) in the category of games, 29 studies (N?=?2553) in the category of games, and 27 studies (N?=?2798) in the category of virtual worlds were meta-analyzed. The key inclusion criteria were that the study came from K-12 or higher education settings, used experimental or quasi-experimental research designs, and used a learning outcome measure to evaluate the effects of the virtual reality-based instruction.Results suggest games (FEM?=?0.77; REM?=?0.51), simulations (FEM?=?0.38; REM?=?0.41), and virtual worlds (FEM?=?0.36; REM?=?0.41) were effective in improving learning outcome gains. The homogeneity analysis of the effect sizes was statistically significant, indicating that the studies were different from each other. Therefore, we conducted moderator analysis using 13 variables used to code the studies. Key findings included that: games show higher learning gains than simulations and virtual worlds. For simulation studies, elaborate explanation type feedback is more suitable for declarative tasks whereas knowledge of correct response is more appropriate for procedural tasks. Students performance is enhanced when they conduct the game play individually than in a group. In addition, we found an inverse relationship between number of treatment sessions learning gains for games.With regards to the virtual world, we found that if students were repeatedly measured it deteriorates their learning outcome gains. We discuss results to highlight the importance of considering instructional design principles when designing virtual reality-based instruction. A comprehensive review of virtual reality-based instruction research.Analysis of the moderation effects of design features in a virtual environment.Using an advance statistical technique of meta-analysis to study the effects.Virtual reality environment is effective for teaching in K-12 and higher education.Results can be used by instructional designers to design the virtual environments.

The potential of digital tools to enhance mathematics and science learning in secondary schools: A context-specific meta-analysis

Abstract: Based on systematic research of studies published since the year 2000, this comprehensive meta-analysis investigated how the use of technology can enhance learning in secondary school mathematics and science (grade levels 5–13). All studies (k = 92) compared learning outcomes of students using digital tools to those of a control group taught without the use of digital tools. Overall, digital tool use had a positive effect on student learning outcomes (g = 0.65, p

Graphic Comprehension and Interpretation Skills of Preservice Teachers with Different Learning Approaches in a Technology-Aided Learning Environment

Abstract: A one-group quasi-experimental design and survey methodology were used to investigate the effect of virtual laboratory practices on preservice teachers’ (N = 29) graphic comprehension and interpretation skills with different learning approaches. Pretest and posttest data were collected with the Test of Understanding Kinematic Graphs. The Learning Approaches Scale was administered to the preservice science teachers to determine if they used an in-depth, superficial, or strategic approach. These data were analyzed using non-parametric statistics. The effect of virtual laboratory practices on these preservice teachers’ graphic comprehension and interpretation skills was evaluated, and a significant pretest–posttest gain for “Selecting the graphic related to the explanation of movement” was found. Suggestions are made to address the effects of teaching models and technology-integrated learning environments on students’ learning approach in science courses at different levels of education.

An Analysis of Scientific Researches in the Field of Technology-Assisted Science Education between the Years 2005-2012

Abstract: This study analyzes the distribution of scientific researches made on technology-assisted science education in Turkey between 2005-2012 by years in terms of type of publication, sample group, research design, data collection tools, the scientific subject used in the content and education material. The study examines the scientific researches made on technology-assisted science education and aims to detect the shortcomings in this field and to guide future researches with the resulting data. The study uses case study design which is a qualitative research design. The universe of the study consists of articles, doctorate and master theses published on technology-assisted science education between the years 2005-2012. For this purpose, articles published in refereed journals reviewed from Ulakbim (Turkish National Academic Network and Information Center) Social Sciences Data Base and master and doctorate theses published by Council of Higher Education Thesis Search Center were included in the research. As for data collection method, documentary analysis was used. For the analysis of data, content analysis was used and the results were presented in percentages and frequency values. As a result of the research, it was found out that majority of the researches on technology-assisted science education were published in the form of master thesis; the subjects studied most were “Systems in our Body” for biology, “structure and properties of matter” for chemistry, “Light and Sound” for physics Oz
