The aim of this study was to investigate how the implementation of GeoGebra by teachers who had recently attended a GeoGebra training course, impacts on learner experience and achievement. The study was conducted in four disadvantaged and under resourced schools situated in rural areas of the Mpumalanga Province of South Africa. Despite the curriculum’s encouragement to use educational technology in the mathematics classroom, and evidence of the benefits of such use, literature indicates that most mathematics teachers still struggle with effective technology integration into their classrooms. Within the non-equivalent quasi-experimental design of this study, a quantitative approach was used. The conceptual framework involved the first two levels of Kirkpatrick’s (1996) four level framework. Four Grade 10 classes comprising of 165 learners participated in this research. Data collection involved a questionnaire administered to the experimental group, as well as pre- and post-tests assessing the achievement of the learners regarding the properties of quadrilaterals administered to both the experimental and control groups. Results from the quantitative data analysis showed a significant difference in the mean scores with a mean difference of 6.5 in favour of learners taught with GeoGebra compared to a chalk and talk method. Implementation of and enthusiasm about GeoGebra had a positive influence on learner achievement. Analysis of the questionnaire responses indicated a positive reaction towards the use of GeoGebra in learning about quadrilaterals. Based on the results, it was concluded that GeoGebra as a pedagogical tool can work effectively in deep rural schools where geometry is hardly taught.

Primiparous Women

Introduction The spouse has a special role in promoting the health of mothers and infants during pregnancy, childbirth, and postpartum. Women's health during pregnancy requires the participation and cooperation of their spouses. Therefore, this study was conducted to determine the effect of face-to-face and virtual prenatal care training of spouses on the pregnancy experience and fear of childbirth of primiparous women. Methods This is a quasi-experimental clinical trial that was conducted on primiparous pregnant women referring to three prenatal clinics in Tehran, Iran. Sampling was done by available method and pregnant women were divided into three groups of face-to-face training ( n = 35), virtual training ( n = 35), and control ( n = 33). The content of training program in the virtual and face-to-face groups was similar and included; nutrition during pregnancy, emotional support, fetal growth and development, advantages and disadvantages of vaginal delivery, planning for delivery, infant care, and danger signs for infants, which were presented in four sessions. The samples in the control group did not receive any training. In the 18th and 20th weeks of pregnancy, the demographic information form, pregnancy experience scale, and version A of the Wijma delivery expectancy/experience questionnaires were completed, and once again in the 37th and 38th weeks of pregnancy, the pregnancy experience scale and version A of the Wijma delivery expectancy/experience questionnaires were completed. Results There was a statistically significant difference in the mean score of pregnancy experience after the intervention between the face-to-face training and control groups ( p = 0.001). There was a statistically significant difference in the mean score of uplifts between the two groups of face-to-face training and control ( p = 0.01), and also between virtual training and control groups ( p = 0.02). There was a statistically significant difference between the two groups of face-to-face training and control in terms of and hassles score after the intervention ( p = 0.04). There was a statistically significant difference between the two groups of face-to-face training and control ( p = 0.02) and also between virtual training and control ( p = 0.04) in terms of the mean score of fear of childbirth after the intervention. Conclusion The results of this study showed that teaching prenatal care to spouses of primiparous women by face-to-face and virtual methods can be a useful intervention in improving the pregnancy experience and reducing the fear of childbirth among primiparous women.

The Impact

Introduction/Objective. The development of speech is the result of interaction of different systems of the cortex, which gradually acquires the ability of phonological presentation and motor control, in the presence of a series of physical and physiological changes in the morphology of the articulation system. The objective of the study was to examine the impact of laterality and cortical responses on the development of speech in children. Methods. Research is a quasi-experimental design with two groups. The sample covered 60 children from Belgrade, of both sexes, ages 5.5?7 years, divided into two groups, experimental (30) and control (30). We used the following instruments: test for assessing laterality and ascertaining evoked potentials. Results. On the visual lateralization subtest there was a statistically significant difference (?2 = 7.56, p < 0.05) between the observed groups. The visual evoked potentials on all measured parameters gave a statistically significant difference between the groups: waveform cortical responses ? left (?2 = 30.00, df = 1, p < 0.05); cortical responses ? right (?2 = 6.667, df = 1 , p < 0.05); waveform amplitude ? left (?2 = 13.469, df = 1, p < 0.05); amplitude ? right (?2 = 40.00, df = 1, p < 0.05), somatosensory potentials (?2 = 18.261, df = 1, p <0.05); waveform amplitude (?2 = 12.000, df = 1, p < 0.05); waveform latency (?2 = 5.455, df = 1, p < 0.05). Conclusion. Visual laterality, as well as visual and somatosensory cortical responses to stimuli is better in children without the present articulation disorder, which could be used for timely prevention planning.

Abstract: This research aims at finding out whether or not the use of chunking strategy is effective in developing students’ ability of story retelling to the tenth-grade students at MAN 01 Pekalongan. Quasi experimental research was applied as the method with two groups : experimental and control group. The total subject of this research was 52 students which were taken from two classes of X IPS 1 as a control group and X AGAMA 2 as an experimental group. Face and content validity were done by asking the English teacher and advisor to be expert judgements to validate the instrument by using a rubric appearance of test for face validity and its conformity by curriculum as a content validity. Inter-rater reliability in giving scores to the students’ was done to measure the reliability of the test. This research used SPSS in analysing the data of speaking test through several activities. They were pre-test before treatments, and post-test after treatments. The result of the research shows the significant difference in the story retelling ability between tenth grade students who were taught by using chunking strategy and those were not taught by using it. It can be seen in the result of mean score in the post-test of experimental class which is 89 and control class which is 83 and as a result Sig. (2-tailed) is 0.044 0.050. Therefore, the null hyothesis of this study is rejected. It means that the use of chunking strategy had significantly improved the tenth-grade students story retelling ability in English teaching and learning process of the experimental class at MAN 01 Pekalongan in the academic year 2019/2020. Keywords:     chunking, teaching speaking strategy, story retelling
