Augmented Reality Trends in Education between 2016 and 2017 Years

The aim of this chapter is to review literature regarding using augmented reality (AR) in education articles published in between 2016 and 2017 years. The literature source was Web of Science and SSCI, SCI-EXPANDED, A&HCI, CPCI-S, CPCI-SSH, and ESCI indexes. Fifty-two articles were reviewed; however, 14 of them were not been included in the study. As a result, 38 articles were examined. Level of education, field of education, and material types of AR used in education and reported educational advantages of AR have been investigated. All articles are categorized according to target groups, which are early childhood education, primary education, secondary education, high school education, graduate education, and others. AR technology has been mostly carried out in primary and graduate education. “Science education” is the most explored field of education. Mobile applications and marker-based materials on paper have been mostly preferred. The major advantages indicated in the articles are “Learning/Academic Achievement,” “Motivation,” and “Attitude”

A practical approach example to measurement uncertainty: Evaluation of 26 immunoassay parameters

IntroductionMeasurement uncertainty is a non-negative parameter that characterizes the distribution of all values appropriate to the measured size and is associated with the measured result. In this study, we aimed to compare the results with various suggestions and produce more qualified results by calculating the measurement uncertainties of the immunoassays like fertility hormones, drug concentration tests, cardiac markers, thyroid function tests and tumour markers. Materials and methodsUncertainty calculation was made in accordance with the top-down approach according to Nordtest guide. The 12-month study of internal and external quality assessment results were used. The parameters of drug concentration tests were performed on the Abbott Architect c8000, other hormones/markers on the i2000 of the same brand. ResultsFactors that increased the measurement uncertainty of a test were due to external quality control data. The calculations showed that 13 of 26 parameters satisfied quality requirements. The highest uncertainty value, with 28% belonged to cancer antigen 19-9 test. The lowest value was calculated for prolactin with 8.3%. Dehydroepiandrosterone sulfate and phenytoin performed poorly in terms of measurement uncertainty, although internal and external quality control assessment results were considered favourable for both. ConclusionIt is recommended that the concept of measurement uncertainty, which plays an important role in the total quality performance of the laboratory, should be followed up by the clinical laboratory experts at certain time intervals and should be increased the awareness of clinicians about the subject

Interaction between Group Work, Motivation and Instructional Feedback in Project-Based Courses

This study aimed to define the relationships between the factors affecting the learning processes of participants in project-based courses. The study sample consisted of 132 participants who had taken in the instructional design course offered at the undergraduate level. The MSLQ, SAGE, and SPIF were used as data collection tools. The findings showed that the conflicts caused by the individuals with negative affect about instructional feedback diminished the quality of product and process during group work. Positive affect was found to be directly affected by ‘extrinsic goal orientation’, which is one of the motivation variables

Društvena prisutnost u trodimenzionalnim virtualnim svjetovima koji se primjenjuju u nastavi na daljinu

The purpose of this study was to examine differences in social presence among students who had participated in a traditional video conference environment and a 3D virtual world for distance education. Also, characteristics of the 3D environment most affected their social presence, and the users’ opinions concerning the 3D environment were revealed. For this purpose, an exploratory, mixed research method was used in this study. Quantitative and qualitative methods were usedto collect and analyze the data. The participants included 40 distance education university students, of which 20 in an experimental group (using a 3D virtual world) and 20 in a control group (using traditional methods). The results indicate that students who used the 3D virtual environment reported notably higher social presence. They perceived 3D virtual world as more social than video conference environment. Also, they found the 3D virtual world warm, interesting, and flexible, and that they were active and sociable within such environment. These results showed that 3D virtual worlds can be used effectively in educational environments for distance education students because they provide a rich social presence.Svrha ovog istraživanja bila je istražiti razlike u društvenoj prisutnosti među studentima koji su se, za nastavu na daljinu, koristili tradicionalnom videokonferencijom i 3D virtualnim svijetom. Osim toga, utvrđena su obilježja 3D okruženja koja najviše utječu na društvenu prisutnost i mišljenja korisnika o 3D okruženju. U ovom istraživanju koristile su se različite istraživačke metode. Za prikupljanje i analizu podataka koristile su se kvantitativne i kvalitativne metode. Uzorak ispitanika činilo je 40 studenata koji studiraju na daljinu, od toga je 20 studenata bilo u eksperimentalnoj grupi (koristili su se 3D virtualnim svijetom), a 20 u kontrolnoj grupi (koristili su se tradicionalnim metodama). Rezultati pokazuju da su student koji su se koristili 3D virtualnim okruženjem imali znatno veću društvenu prisutnost. 3D virtualni svijet doživjeli su društvenijim nego videokonferenciju. Uz to su uvidjeli da je 3D virtualni svijet pristupačnije, zanimljivije i fleksibilnije okruženje unutar kojeg su bili aktivni i društveni. Ti rezultati pokazuju da 3D virtualni svjetovi mogu biti učinkovita obrazovna okruženja za studij na daljinu zato što omogućuju veću društvenu prisutnost

Prospective Preschool Teachers’ Academic Achievements Depending on Their Goal Orientations, Critical Thinking Dispositions and Self-Regulation Skills

The aim of this study is to explain and predict prospective preschool teachers’ academic achievements depending on goal orientations they adopt, their critical thinking dispositions and self-regulation skills. Research sample constitutes of 265 prospective preschool teachers attending the Faculty of Educational Sciences in Cukurova University. Research data were collected with the 2x2Achievement Goal Orientations Scale, Self-Regulation Questionnaire and Critical Thinking Disposition Scale. Demographical information about prospective teachers’ gender, age, grade level and academic grade point averages were obtained with the personal information form. For the analysis of research data, One-Way Analysis of Variance (ANOVA) and discriminant analysis were used. In this study; it was concluded that prospective teachers with high level of learning approach orientation, critical thinking disposition and self-regulation skills had higher levels of academic achievement. However, it was determined that distinguishing variables among prospective preschool teachers with low, medium and high level of academic achievement included learning approach, performance approach goal orientation and critical thinking disposition and self-regulation skills. Correct classification percentage of distinguishing variables according to prospective preschool teachers’ levels of academic achievement was determined as 48.8%. Considering the fact that prospective teachers’ achievement-goal orientations, critical thinking dispositions and self-regulation skills may increase their academic achievement and shape their future teaching performances, it is suggested to implement programs that will contribute to the development of such skills and orientations among prospective preschool teachers

Parkinson’s Disease and Narcolepsy-Like Sleep Episodes

A fifty one-year-old male patient presented with the complaint of sudden daytime sleep episodes for the last one and a half years. The patient had been diagnosed with Parkinson’s disease for four years and has been administered treatment of ropinirole 4 mg XL and rasagiline 1 mg tablet. The patient reported that his complaints occurred with the addition of pramipexola 0.750 mg/day tablet. Excessive daytime sleepiness occurred as sudden sleep episodes without giving any prior signs and subsided spontaneously after which the patient felt rested. The patient was diagnosed with severe obstructive sleep apnea syndrome and hypersomnia depending on medical disease and drug side effects with polysomnography and multiple sleep latency test

Razrada popisa kriterija za odabir 3D virtualnih svjetova i izradu obrazovnog okruženja

The purpose of this study was to develop a criteria list to be considered during the selection of 3D virtual world platforms for educational purposes. As the first step in this process a draft list was created by the researchers based on literature review and heuristic investigation. The draft list was reviewed and revised by 2 internal and 4 external experts, and then used as a questionnaire. The items in the finalized criteria list were divided into three categories as follows: 50 items of technical specifications (system/program features, usability, software tools, multimedia tools, security, and cost), 21 items of interaction specifications (avatars, activities, communication tools) and 8 items of educational specifications (teaching/learning activities). Ultimately, the developed criteria list will be helpful for identifying and eliminating the deficiencies and constraints of virtual worlds used for educational purposes.Svrha ovog istraživanja bila je razrada popisa kriterija koje treba uzeti u obzir prilikom odabira 3D virtualnih platformi u obrazovne svrhe. U tom su procesu znanstvenici najprije sastavili nacrt kriterija na osnovi proučene literature i heurističkog istraživanja. Dva naša i četiri vanjska stručnjaka pregledala su i napisala osvrt na nacrt kriterija koji se zatim koristio u obliku upitnika. Završni popis kriterija podijeljen je u sljedeće tri kategorije: 50 tehničkih kriterija (osobine sustava / programa, iskoristivost, softverski alati, multimedijski alati, sigurnost, cijena), 21 kriterij vezan uz interakciju (avatari, aktivnosti, komunikacijski alati) i 8 obrazovnih kriterija (aktivnosti poučavanja / učenja). Na kraju će razrađeni popis kriterija pomoći u utvrđivanju i uklanjanju nedostataka i ograničenja virtualnih svjetova koji se koriste u obrazovne svrhe
