We develop a web-application for practice of listening skills by learners of English, which allows users to listen to pre-recorded sound-files and respond to multiple-choice questions. They receive feedback as to the accuracy of their responses, and they are navigated through the set of items in one of two ways according to the group they are randomly assigned to. Members of a control group are guided from one item to the next depending on success or failure with each new item, and the difficulty ratings of the remaining items. For the experiment group, item selection is made in an adaptive fashion: selecting items through automatic predictions based on individual performance and observations of other students’ interactions with the platform, as well as known item attributes obtained through tagging. Based on the cognitive literature, we also provide listeners with the option of controlling the speed of presentation of the listening items.

University students in Vietnam do not have enough time to practise their listening inside the classroom. Outside the classroom, they do not have chance to practice it. To supplement time constraint in the classroom, extensive listening was employed to assist students to develop their listening skills. The study aims to investigate whether extensive listening ameliorates students’ listening proficiency. Two groups of students from two intact classes: the control group (n = 32) and the experimental group (n = 32) were selected. Before the semester started, all students sat for the pre-listening test.  After that, students in the experimental group were advised to listen to fifteen suggested sound files with one file for each week. They were also instructed some listening strategies to self-practise at home while students in the control group did not do any listening tasks at home. After 15 weeks, students in both groups took the post-listening test. The post-interview was conducted to explore how students practiced their listening out of school. The results showed that the experimental group outperformed the control group in the post-test. Some students in the experimental group reported that they practised listening many times and tried to learn as much vocabulary as possible.

Teaching Learning

The use of information and communication technologies (ICTs) has become a fundamental tool in all areas of today’s society, including higher education. Lessons cannot be envisaged without the use of tools such as computers, tablets or mobile devices. Many lecturers use audience response systems (ARS) to keep their classes engaged. ARS software allows teachers to interact with students via polls, text responses, or multiple-choice questions displayed via their mobile devices. A new example of the use of this type of devices in education is gamification, a technique that uses a set of activities with ludic character as a learning methodology in order to facilitate the acquisition of knowledge and competences. One of the most used gamification tools is Kahoot!, a free learning application based on a mixture of game and creativity, which encourages attention and participation of students through questions and answers formulated by the teacher and designed in a way that students respond via their mobile phones. This paper examines the use of Kahoot! in a subject belonging to the chemistry area. In order to assess the benefits of this tool, it was tested in a group of students to review the knowledge and skills acquired during the theoretical lessons prior to the exams, and the academic results were compared with those of a control group of students who did not use the tool. The results demonstrate that the use of Kahoot! led to an improvement in the teaching–learning process of the students and a noteworthy rise in their marks, and that its positive effects rise with increasing the frequency of use of this didactic tool.

ABSTRACT: The present study evaluated the efficacy of a single oral dose of doramectin in the control of Psoroptes ovis and Leporacarus gibbus in naturally infested rabbits. Sixteen adult rabbits were selected and distributed in two experimental groups. The treated group received 200 μg/Kg of oral doramectin and the control group received the same volume of saline solution. The diagnosis of the mites was made with a stereoscopic microscope. Hairs from the dorsal part of the neck, lumbar right, lumbar left, ventral side of the tail and ventral abdomen were evaluated for L. gibbus, and ear wax evaluated for P. ovis. The evaluation of the efficiency and the clinical assessment of the lesions was made in days 0, +3, +7, +14, +21, +28, and +35 after treatment. An efficacy of 75% and 87,5% was observed for L. gibbus in days +3 and +7 after treatment, an efficacy of 100% was observed in days +14, + 21, +28 e +35. An efficacy of 100% for the control of P. ovis was observed following day +7. The clinical lesion score of the control group remained unaltered, except for one animal which conditions worsened during experimentation. In the treated group animals, regression of the lesions was observed following day +3, and on day +21 no signal of infestation by P. ovis was present. None of the animals from the treated group presented secondary collateral effects caused by the doramectin, which proved itself as an optimal alternative for mite control in naturally infested rabbits.

The effects of audience response systems (ARS) on students' academic success and their perceptions of ARS were examined in this study. Participants, comprising 44 undergraduate students, were randomly assigned to a control or treatment group. The course design was the same for both groups and the instructor prepared the multiple-choice questions in advance; students in the control group responded to these questions verbally whereas the treatment group used ARS. Two paper-based examinations were used to measure the learning of concepts and skills that were taught. Students' perceptions of ARS were collected via a questionnaire. Results showed that ARS usage has a significant learning achievement effect in the first 4 weeks but not at the end of the second 4 weeks. There was no significant difference in retention between either group. Students perceived the ARS tool positively, finding it very enjoyable and useful.

Reading ability seems to involve analytic-sequential processing of selected letters and a holistic-simultaneous perception of the salient features of the entire word. The dyslexic child, being normal in intelligence, is most likely deficient in either one of the two processes while being normal in the other. To test this hypothesis, 28 reading disabled children, on the basis of the nature of errors made in a writing from dictation task, were divided into two groups: analytic-sequential deficient and holistic-simultaneous deficient. Further testing showed that the first group was poor in processing a sequence of digits but normal on holistic-simultaneous memory tasks. The opposite pattern of performance was shown by the second group. A control group of 14 normal readers did not show such an imbalance.

In spite of the advances made in orthodox medicine, there has been an increasing interest in herbal medicine. The leaves of Carica papaya and Pakia biglobosa have been reported to contain lots of beneficial medicinal compounds, hence their use in the traditional prevention, management and treatment of ailments/diseases. In this study, the effect of varied concentrations of the ethanol leaf extract of the plants on some biochemical parameters of albino rats was assessed. The phytochemical compositions of the leaves were determined using established standard laboratory methods. Fifty four male Albino rats weighing between 150g-200g were randomly distributed into nine groups of six animals each. A daily single dose of 500mg/kg, 1000mg/kg, 1500mg/kg and 2000mg/kg body weight of either of the extracts was respectively, administered to the eight test groups for fourteen days. The control group was given only feed and water. Biochemical parameters such as the serum activities of Aspartate Aminotransferase, Alanine Aminotranferase and Alkaline phosphatase as well as the serum concentrations of Bilirubin, Albumin, HCO3-, Urea, Creatinine and Na+ were assessed. Result of the analyses showed that the administration of the extracts did not significantly raise the serum activity of ALT. The decreases in serum concentrations of Urea and increase in the concentration of HCO3- were directly proportional to the concentration of the extracts. It can be deduced from this study, that 500mg, 1000mg 1500mg and 2000mg/kg bw of either C. papaya or P. biglobosa did not elicit any marked hepatotoxicological or renotoxicological effect on the experimental animals

Abstract The Cerebral Vascular Accident is responsible for a significant increase in the mortality rate in individuals who have suffered this condition, regardless of the level of subsequent disability. This study aimed to analyze the influence of a strength training program on indicators of depression in survivors of the ischemic stroke. The study sample included subjects from both genders who were divided into two groups: an experimental group (EG) consisting of 11 subjects aged 51.7 8.0 years, and a control group (CG) consisting of 13 subjects aged 52.5 7.7 years. The EG underwent 12 weeks of strength training. Assessment was made in the pre-test before training and at the re-test after 12 weeks of training. We used the Beck Depression Inventory and evaluated 1RM. Significant differences in depression were found between post-test and pretest measurements (Δ% = -21.47%, p = 0,021) in the EG; furthermore, there were significant differences in all indicators of depression between the EG and CG after completing 12 weeks of training. There were significant gains in strength of the EG in relation to the CG. There was a negative correlation between the strength gains as determined with the 1RM test and the levels of depression, especially in lower-limb exercises. The results of this study suggest that improvements in strength are negatively correlated with levels of depression. Improvements in strength are therefore associated with a reduction in levels of depression.

Mastery of keyboarding being part urgent to communicate through the computer, and very important, especially students who study in the field of business. On the other side, individual performance also influenced by the work environment, and music is one form the environment that could effect keyboarding performance. A model that can describe this is the stimulus-responsible model of mehrabian-russell which explains that music can affect the performance of individual writing. Almost all of Indonesia has traditional music. Therefore, research is needed to identify the effects of traditional music to enrich the area of innovation in strategies and techniques of learning keyboarding skills. In this study conducted an experiment on two groups, the treatment groups(traditional music) and control group (without traditional) and questionnaire to strengthen the experimental results. In preliminary tests of typing, both groups had a mean AWPM identical or similar. Furthermore, tests carried one, where the treatment group listened to five kinds of music Java, Sunda, and Bali. The test result and the result of the questionnaire showed that (typing skills shown by the average value of AWPM) will increase significantly used of traditional music as the background. So, the genre of traditional music can be stimulant to improve average performance of AWPM. There are three traditional kinds of music that can improve student typing speed and accuracy significantly, a regional music cublek-cublek suweng, kebiar bali, and oleg tambuliningan, but cublek-cublek suweng is a genre of traditional music that has the best effect. Therefore, the process of learning courses keyboarding skills needs to use instrumental traditional music, especially instrumental music that has a fast and cheerfully tempo.
