Technological Intervention

AbstractIn this report it is presented the results of a longitudinal pre-experimental study, it was realized a technological intervention to stimulate the phonological awareness through a tangible reading toy based on the RFID technology, consisting of a teddy bear and 30 letters in 3D from the Spanish alphabet. This study started with a sample of 200 children, from them, there were selected 17 children aged between 6 and 7 years (Mage = 6.47, SD = .51) with a phonological disorder from an educative institution. The procedure consisted of obtaining pre-test and post-test values with the Evaluation of Phonological Awareness (PECFO). Sampling inclusion criteria considered children presenting problems of phonemes’ recognition and its relationship with graphemes. During 30 weeks it was realized an intervention with the technological toy and at the end of the sessions, it was applied the post-test. Results of phonological awareness showed statically significant differences among the pre (M = 12.88, SD = 3.53) and post-test (M = 17.17, SD = 2.96) this contributes to the empirical evidence of the intervened group improvement in this cognitive function t(16) = −3.67, p = .002. From this research it is projected proposing technological innovations contributing in the treatment of children’s cognitive difficulties.

Semantic Aspect

This study analyzed the development of phonological, semantic, and syntactic aspects by using augmented reality and interactive whiteboard with boys and girls in the kindergarten of Liceo San Felipe, San Felipe, Chili. With the implementation of these tools, learning experiences were carried out, enhancing the understanding of sentences and words in their successive components: linguistic segmentation, phonological awareness, and reflection on the meaning of words and sentences. The experiments were carried out in a didactic classroom of the course of Educacion Parvularia (Pre-School Education) at the University of Playa Ancha, San Felipe Campus, for 60 minutes, once a week for four months. It was a quasi-experimental study, and through pre- and post-tests, it was possible to verify the development of 18 children of a municipal school in San Felipe. The instruments used were the Linguistic Segmentation Test, Comprehensive and Expressive Language Examination Test (ELCE); Subtest semantic aspect, Test Evaluation O; Subtest words and phrases. The results, based on the comparison of pre- and post-test, showed changes in the management of the semantic, syntactic, and phonological aspects achieved by the children with this methodology. However, more research is needed to validate this proposal in teaching metalinguistic.

Mouthwash is an additional mechanical oral cavity cleaning method which is known to reduce oral bacterias that causes plaque build ups. Mouthwash may and may not contain alcohol. The objective of this study was to determine the alterations on the oral cavity environment (salivary pH and plaque index) before and after gargling with alcohol and non-alcohol mouthwash, and to analyze which of the mouthwash is more effective. This study was an experimental study with one group pre test and post test experimental design. The subject of this study was 16 of University of Sumatera Utara’s female undergraduates whose age ranges from 18–23 years old and accorded to the inclusion and exclusion criteria. Subjects were divided in two groups, subjects were instructed to used the mouthwash twice a day for seven days, then salivary pH and plaque index were measured at third and seventh day of used. Repeated Annova test results shown a significant decreas on salivary pH and plaque index after gargled with mouthwash containing alcohol, in the non-alcohol mouthwash there was a significant decreased in plaque index but none on the salivary pH. Dependent T-test results shown that there were no difference in salivary pH and plaque index after gargled with alcohol containing and non-alcohol mouthwash. This study shows that non-alcohol mouthwash is better because there were a significant decrease in plaque index, without caused significant decreases in pH scores.

The aim of this research is to investigate whether there is a meaningful difference in the academic success, between the students who are applied the "formula t-shirt method" (experimental group) and the students who are not (in other classes of the school), in the education for the scientists wanted to be taught in the secondary school 5th, 6th and 7th grade science textbooks. Semi-experimental method was used as research method. In the 6th grade, 27 students participated in this study as experimental group (students wearing t-shirts) and 49 students in the other classes of the school that did not participate in the study. Academic achievement test including pre-test and post-test, informative observations, students’ and teacher’s interviews as well as 20 printed t-shirts were used to collect data. The pilot study of the developed achievement test was applied in another school and also the item analysis of it was performed. According to the research findings, when the experimental group’s success post-test results from the application performed, were examined in line with the interviews, significant differences were observed. It was seen that the subjects aimed to be gained with the formula t-shirt method, were adopted by the students and also increased their success. Looking at the results of the research, thanks to wearing the t-shirts prepared by using the human body on the background, and the reconciliation of the students wearing with the scientists on t-shirts, the desired learning was provided. This also contributed to such learning techniques as peer learning, active learning, social learning in terms of visuality and integrity. It is thought that these materials developed with the formula t-shirt method, will also inspire researchers for future studies in terms of their usability in other fields and subjects

This study attempts to determine whether gamification can be used as a pedagogical technique to overcome the challenges in teaching statistics. A post-test quasi-experimental design was carried out in gamified and non-gamified groups in order to reveal the effect of gamification elements in cultivating students’ statistical literacy skills. Students in gamified group were also interviewed to understand the function of gamification process. The results suggest that; although gamifying the instructional process had a positive impact on developing students’ statistical literacy in medium and high score students; surprisingly the influence of the gamification to the low- achieved scores were not positive. The positive impact was discussed in accordance with the gradual structure of statistical literacy and suggestions for successful gamification applications due to the context were included.

Abstract Background Social isolation and loneliness have each been associated with cognitive decline, but most previous research is limited to Western populations. This study examined the relationships of social isolation and loneliness on cognitive function among Chinese older adults. Methods This study used two waves of data (2011 and 2015) from the China Health and Retirement Longitudinal Study and analyses were restricted to those respondents aged 50 and older. Social isolation, loneliness, and cognitive function were measured at baseline. Follow-up measures on cognitive function were obtained for 7761 participants (mean age = 60.97, s.d. = 7.31; male, 50.8%). Lagged dependent variable models adjusted for confounding factors were used to evaluate the association between baseline isolation, loneliness, and cognitive function at follow-up. Results Loneliness was significantly associated with the cognitive decline at follow-up (episodic memory: β = −0.03, p < 0.01; mental status: β = −0.03, p < 0.01) in the partially adjusted models. These associations became insignificant after additional confounding variables (chronic diseases, health behaviors, disabilities, and depressive symptoms) were taken into account (all p > 0.05). By contrast, social isolation was significantly associated with decreases in all cognitive function measures at follow-up (episodic memory: β = −0.05, p < 0.001; mental status: β = −0.03, p < 0.01) even after controlling for loneliness and all confounding variables. Conclusions Social isolation is associated with cognitive decline in Chinese older adults, and the relationships are independent of loneliness. These findings expand our knowledge about the links between social relationships and the cognitive function in non-Western populations.
