Improving Students’ Vocabulary Mastery Using Songs (Classroom Action Research at English Class B of Information Technology Program in Wira Wacana Christian University Sumba)

Pronunciation is focus on how to pronounce and produce the word. Students should be careful in pronouncing the word because in English there are some vocabulary that have almost similar pronunciation but different meaning. This research is Classroom Action Research (CAR). Classroom Action Research is a method of finding out what works best in your own classroom so that you can improve student learning. Method which was used in this research qualitative method research. Based on the diagram above, the students’ score in doing the test in cycle 2 can be seen that the percentage of students’ vocabulary mastery after songs were they got 49,44 for pronunciation, 71,84% for spelling, 37,04 for Grammar, 68,80% for Meaning. From the explanation, it could be concluded that only two of the vocabulary components that reach the target of minimum standard score: Spelling and Meaning. Teaching vocabulary using songs is one of the alternative solution, that teacher can use to teach vocabulary to their students. It makes students more relax in learning new words and they can memorize them easily

INFLUENCE OF THE ATTITUDE OF TEACHERS ON ACADEMIC PERFORMANCE OF VISUALLY IMPAIRED LEARNERS IN PRIMARY SCHOOLS OF RONGO SUB-COUNTY, KENYA

Visual impairment has a negative impact on the learner’s ability to learn. In Kenya learners with visual impairment experience problems interacting with the learning environment just like other learners with other forms of impairment. The purpose of the study was to investigate the influence of the Attitude of Teachers on Academic Performance of Visually Impaired Learners in Primary Schools of Rongo Sub-County, Migori County, Kenya. The study was based on Bandura’s (1968) Social Cognitive Theory of learning which outlines the process of learning as a result of the surrounding environment. The study employed a descriptive survey design. The study population included 29 headteachers of public primary schools with the integrated program, 40 Special Needs Education (SNE) Teachers and 5 Curriculum Support Officers (CSOs) giving a total of 74 respondents. Purposive and Saturated sampling techniques were used to get a sample size of 29 headteachers, 40SNEteachers and 5 CSOs. Reliability of research instruments was done through piloting on 4 SNE teachers, 3 headteachers and 1 CSO in UririSub-County. Using the test-retest technique, a reliability index of 0.79 and 0.81 was attained for teachers’ and headteachers’ questionnaires respectively. The reliability test for the interview schedule was carried out by parallel-form reliability. The content validity of instruments was established by presenting the instruments to an expert for confirmation. Quantitative data was analyzed using descriptive statistics of frequencies, percentages and means and Inferential statistics of Pearson Correlation Coefficient and Chi-square. Qualitative data was analyzed based on emerging themes generated from the study objective. Data were analyzed using the Statistical Package of Social Sciences (SPSS) version 22. Frequency and percentage tables were used to present collected data. The study established that there was a significant relationship between teachers’ attitude and teaching learning materials and academic performance at p <0.05. Therefore the null hypothesis was rejected and it was concluded that teachers’ attitude affect academic performance in Integrated Primary Schools in Rongo Sub-County. From the study it was recommended that teachers handling visually impaired learners should work on their attitude to improve the performance of visually impaired learners; teaching and learning materials that are relevant and appropriate should be made available to visually impaired learners in order to aid their academic performance. Research findings will assist in identifying appropriate teaching methods, teacher training, and a conducive working environment to boost teacher morale and adequate teaching and learning resources.  Article visualizations

Caractérisation de la translocation (12;13)(p12;q12-14) et l’insertion (X;6)(p11.23;q21q23.3) dans des leucémies aiguës pédiatriques

Par une stratégie de dépistage combinant le caryotype et l’hybridation in situ en fluorescence (FISH), une insertion (X;6) présente chez des jumelles avec une leucémie myéloïde aiguë (LMA) et une translocation (12;13) dans deux cas de LMA et un cas de leucémie lymphoblastique aiguë (LLA) ont été mis en évidence. L’insertion (X;6) n’est pas rapportée et serait un variant de la translocation (X;6) rapportée dans 4 cas de LMA, dont un associe un gène de fusion MYB-GATA1. Nous avons mis en évidence la dérégulation de l’expression de ces gènes dans le cas d’insertion sans la présence de fusion MYB-GATA1. De plus, dans le premier cas de translocation (12;13) identifié, ETV6 serait fusionné à CDX2 ou FLT3. Le deuxième cas associe la délétion des gènes miR-15a et miR-16-1 à une fusion d’ETV6 et le troisième cas impliquerait une fusion ETV6- FOXO1.By a screening strategy combining standard cytogenetics and fluorescent in situ hybridization (FISH), an insertion (X;6) in twins with acute myeloid leukemia (AML) and a translocation (12;13) in 2 cases of AML and a case of acute lymphoblastic leukemia (ALL) have been identified. Insertion (X;6) is not reported and could be a variant of translocation (X;6) described in 4 cases of AML, one of which is associated with a MYB-GATA1 fusion gene. We have identified the disruption of MYB and GATA1 in the insertion but no MYB-GATA1 fusion seems to be present. Other mechanisms could be in play for the disruption of these genes’ expression. Moreover, in the first case of translocation (12;13) identified, ETV6 is fused to either CDX2 or FLT3. The second case associates the deletion of miR-15a and miR-16-1 genes to an ETV6 fusion. In the third case, an ETV6- FOXO1 fusion seems to be involved

Assessing the food preference of the brushtail possum (Trichosurus vulpecular) using fixed-ratio schedules

The quality of different foods has been found in previous studies to effect an animal’s performance on fixed-ratio schedules. Foods that are of a higher quality should maintain behaviour to larger fixed-ratio values than foods of a lower quality. The present study examined the performance maintained by increasing fixed-ratio schedules by four different foods (Rolled Oats, Cocoa Puffs™ and flaked barley, All Bran™ and Soy Protein) with six brushtail possum (Trischosurus vulpecula). Overall response rates and running response rates both generally showed a bitonic function, and post-reinforcement pauses showed a modest increase with increases in the fixed-ratio. The equations of two quantitative models; Behavioural economics and mathematical principles of reinforcement (MPR) were fitted to the data to see how different food types affected the two models ability to predict behaviour. This was measured through two parameter estimates, alpha (α) and specific activation (αs). Both demand equations and the MPR equation described the data fairly well. The parameter estimates for specific activation (αs) showed a significant difference in value across the foods, but there was no significant difference across foods for parameter estimates of alpha (α). There was a weak correlation between parameter estimates of α and αs (r =-0.245, p =0.0926) . The four foods used in this study were also tested in a paired-stimulus preference assessment. The foods that were assessed as being of more value in the behavioural economic equations and the MPR model, for some possums were identified as being more preferred, but this was not consistent for all possums
