METHODS: The researchers carried out database search in both Web of Science and the Scopus for relevant articles using 15 related key terms. Finally, forty journal articles aligned with the inclusion criteria.
RESULTS: The results found that gamification has been widely utilized in more than ten non-English-speaking countries and various English language skills, which indicated that gamification has gained popularity in facilitating EFL/ESL learning. The benefits of using gamification included improving students' English language skills and abilities, positively affecting students' attitudes and emotional responses, providing an authentic language learning environment and cultivating students' comprehensive competence. The drawbacks of using gamification mainly included the technical problems, short-lived positive effect, and the negative influence caused by the gamified competition, and so forth. The most frequently used gamification elements were feedback, points, quiz, digital badges, leaderboard, and reward, followed by progress bar, story-telling, challenge, videos, time limit, and competition.
DISCUSSION: The results provide a better understanding of the state of using gamification in EFL/ESL instruction in recent years. It will be useful for researchers seeking to understand and evaluate gamification as well as to practitioners interested in using gamification.
DATA SOURCE: The China National Knowledge Infrastructure and MEDLINE databases were searched. The systematic review with meta-analysis included genetic studies which assessed the association between neonatal hyperbilirubinemia and 388 G>A, 521 T>C, and 463 C>A variants of SLCO1B1 between January of 1980 and December of 2012. Data selection and extraction were performed independently by two reviewers.
SUMMARY OF THE FINDINGS: Ten articles were included in the study. The results revealed that SLCO1B1 388 G>A is associated with an increased risk of neonatal hyperbilirubinemia (OR, 1.39; 95% CI, 1.07-1.82) in Chinese neonates, but not in white, Thai, Latin American, or Malaysian neonates. The SLCO1B1 521 T>C mutation showed a low risk of neonatal hyperbilirubinemia in Chinese neonates, while no significant associations were found in Brazilian, white, Asian, Thai, and Malaysian neonates. There were no significant differences in SLCO1B1 463 C>A between the hyperbilirubinemia and the control group.
CONCLUSION: This study demonstrated that the 388 G>A mutation of the SLCO1B1 gene is a risk factor for developing neonatal hyperbilirubinemia in Chinese neonates, but not in white, Thai, Brazilian, or Malaysian populations; the SLCO1B1 521 T>C mutation provides protection for neonatal hyperbilirubinemia in Chinese neonates, but not in white, Thai, Brazilian, or Malaysian populations.
