The dynamics of the social interaction within the cooperative learning group are accepted and considered to be one of the aspects that will influence the individual learner's feelings regarding the group activity. The impact of the groupings on the quality and quantity of the observable learning within the class is considered. For this study the cooperative learning groupings were manipulated, considering aspects of the learner's social relationships uncovered with the use of a social questionnaire, which the learners completed. These details were summarised by means of a sociometric table and a sociogram. This study approaches the topic from two main perspectives. Primarily observation and naive sketches, from the learners, formed the source of the data and provided the initial perspective on the area of study. From the viewpoint provided in this information specific grouping paramaters were applied to later groups of learners, and a survey conducted. / Educational Studies / M. Ed. (Socio-Education)

Indiana University-Purdue University Indianapolis (IUPUI) / To access interactive systems, blind and visually impaired users can leverage their auditory senses by using non-speech sounds. The current structure of non-speech sounds, however, is geared toward conveying user interface operations (e.g., opening a file) rather than large theme-based information (e.g., a history passage) and, thus, is ill-suited to signify the complex meanings of primary learning material (e.g., books and websites). In order to address this problem, this dissertation introduces audemes, a new category of non-speech sounds, whose semiotic structure and flexibility open new horizons for facilitating the education of blind and visually impaired students. An experiment with 21 students from the Indiana School for the Blind and Visually Impaired (ISBVI) supports the hypothesis that audemes increase the retention of theme-based information. By acting as memory catalysts, audemes can play an important role in enhancing the aural interaction and navigation in future sound-based user interfaces. For this dissertation, I designed an Acoustic EDutainment INterface (AEDIN) that integrates audemes as a way by which to vividly anticipate text-to-speech theme-based information and, thus, act as innovative aural covers. The results of two iterative usability evaluations with total of 20 blind and visually impaired participants showed that AEDIN is a highly usable and enjoyable acoustic interface. Yet, designing well-formed audemes remains an ad hoc process because audeme creators can only rely on their intuition to generate meaningful and memorable sounds. In order to address this problem, this dissertation presents three experiments, each with 10 blind and visually impaired participants. The goal was to examine the optimal combination of audeme attributes, which can be used to facilitate accurate recognitions of audeme meanings. This work led to the creation of seven basic guidelines that can be used to design well-formed audemes. An interactive application tool (ASCOLTA: Advanced Support and Creation-Oriented Library Tool for Audemes) operationalized these guidelines to support individuals without an audio background in designing well-formed audemes. An informal evaluation conducted with three teachers from the ISBVI, supports the hypothesis that ASCOLTA is a useful tool by which to facilitate the integration of audemes into the teaching environment.

This study aims to explore politeness shown by lecturers during tuition and student support conversations with the objective of promoting polite interactions between IsiZulu mother tongue and non-mother tongue speakers in higher education in South Africa. In particular, the study investigates the way in which politeness in email communication influences learning outcomes within an ODL environment, using quantitative and qualitative research methodologies, a questionnaire as well as interviews to collect data from a cross-section of students from an Open Distance Learning (ODL) institution. All the results drawn from the data sources, namely the questionnaires and interviews, were enumerated according to the data collection tools used. Version 12 of SPSS and Nvivo were used to analyse the quantitative data. The analysis is also based on the politeness strategies of Brown and Levinson (1978) as well as a conceptual framework that links all the variables. Based on the results, the research hypotheses are accepted, thus indicating that politeness in email communication influences learning outcomes within an ODL environment. In particular, the results show that, overall, lecturers who employ politeness contribute positively to student compliance. Accordingly, the study recommends that ODL should recognise both the role of language in communication as well as the power and influence of politeness in communication. / African Languages / D.

It was observed that most students had no knowledge about the area, but his interest was increasing during the development of the work, bringing suggestions for discussion and exploring other areas of knowledge, demonstrating the interdisciplinary potential and contextualizing of ICT used. It was also possible to identify the development of skills and abilities of students at work. Are research products: a didactic sequence, posting Laifi in the category education and culture and a tutorial for using the software that can be adapted by teachers according to desired area.

The study was carried out to: (1) determine the relationship between English and mathematical literacy scores at Grade 12 in Moloto Circuit, (2) understand and describe the learning difficulties experienced by learners when English language was used as a medium of instruction, and (3) suggest guidelines that could be used in teaching mathematical literacy. Regression and correlation analyses were carried out to determine the functional and strength of relationship between English language and mathematical literacy in the ten schools of Moloto Circuit. The views of the learners on the use of English language in the learning of mathematical literacy and the use of technical terms were sourced and analysed. The views of the educators about the use of English language as the medium of instruction were also analysed. A mixed approach methodology was used since both quantitative and qualitative methods were employed. The target population consisted of 305 learners who wrote the Grade 12 public examinations in 2016, 585 Grade 12 learners and 10 educators who completed questionnaires in January 2017. A census approach was carried out because everyone in Moloto Circuit doing Mathematical Literacy at Grade 12 level and their educators were studied. Grade 12 results for English and Mathematical Literacy for the 2016 academic year were collected and analysed. Questionnaires with closed and open-ended items were administered on Grade 12 learners and educators for the 2017 academic year in January 2017. Results in the ten schools showed that there was a positive relationship between performances in the two areas. In all cases the computed correlations were significant. This suggested that English influenced performance in Mathematical Literacy. This was supported by coefficients of determination calculations which ranged from 15% to 40%. Most responses indicated that learners found Mathematical Literacy difficult when English language was used as the medium of instruction. The learners preferred that Mathematical Literacy be taught in their mother tongue and that educators explain technical terms associated with mathematics. The educators said that learners had problems in Mathematical Literacy because of the use of English as the medium of instruction. They also said that learners found it difficult to relate Mathematical Literacy questions to real life situations and that the learners lacked adequate practice. The educators recommended the use of code-switching in their teaching in order to enhance understanding of Mathematical Literacy. / Mathematics Education / M. Ed. (Mathematics Education)

Indiana University-Purdue University Indianapolis (IUPUI) / Recent technological applications have made the life of people too much dependent on Science, Technology, Engineering, and Mathematics (STEM) and its applications. Understanding basic level science is a must in order to use and contribute to this technological revolution. Science education in middle and high school levels however depends heavily on visual representations such as models, diagrams, figures, animations and presentations etc. This leaves visually impaired students with very few options to learn science and secure a career in STEM related areas. Recent experiments have shown that small aural clues called Audemes are helpful in understanding and memorization of science concepts among visually impaired students. Audemes are non-verbal sound translations of a science concept. In order to facilitate science concepts as Audemes, for visually impaired students, this thesis presents an automatic system for audeme generation from STEM textbooks. This thesis describes the systematic application of multiple Natural Language Processing tools and techniques, such as dependency parser, POS tagger, Information Retrieval algorithm, Semantic mapping of aural words, machine learning etc., to transform the science concept into a combination of atomic-sounds, thus forming an audeme. We present a rule based classification method for all STEM related concepts. This work also presents a novel way of mapping and extracting most related sounds for the words being used in textbook. Additionally, machine learning methods are used in the system to guarantee the customization of output according to a user's perception. The system being presented is robust, scalable, fully automatic and dynamically adaptable for audeme generation.

Text in English, abstracts and keywords in English, Afrikaans and Zulu / Secondary educational institutions need to constantly scan their environment for crises that could hamper their operations and hinder the achievement of their organisational objectives. These institutions should also engage their strategic stakeholders in a mixed motive communication to collaboratively discuss the crises and find amicable solutions; thereby avoiding crises like the proliferating student strikes in secondary educational institutions in Kenya. This study explored the need for a customised Proactive Crisis Communication Process (PCCP) framework for secondary educational institutions in Kenya to avoid student strikes. A two-phased approach was adopted to collect the data. The first phase involved 12 one-on-one semi-structured interviews with the principals of the secondary educational institutions in Mirangine Sub-County, while the second phase involved five focus group discussions with the students of Ruiru Secondary School. The results indicated that student strikes in secondary educational institutions in Kenya were proliferating and that despite this, these institutions lack proactive measures to avoid strikes. Hence, this study posited a PCCP framework that proposed various proactive measures to avoid student strikes in secondary educational institutions in Kenya. / Sekondêre opvoedkundige instellings moet konstant hul omgewing ondersoek vir krisisse wat hul bedrywighede kan belemmer en die bereiking van hul organisatoriese doelwitte kan verhinder.

Abstracts in English, Sesotho and Xhosa / Through learner progression in South African primary and lower secondary public schools, many learners proceed to the Further Education and Training (FET) Phase without proficiency in English First Additional Language (EFAL), the language of learning and teaching (LoLT). Compelled by this challenge, this multiple-case study aimed to explore the lived experiences of grades 10 and 11 teachers in teaching progressed learners to enhance communication proficiency in EFAL. The study was informed by a qualitative research approach, embedded in a constructivist paradigm, guided by Vygotsky (1978) social development theory. Observations and one-on-one, semi-structured interviews were used to collect data from a sample frame of five grades 10 and 11 EFAL teachers in selected rural secondary schools and thematic analysis was used for data analysis. Findings revealed that in this era where learner diversity requires differentiated teaching that appeals to the needs of diverse learners, teachers hold on to the past training one-size-fits-all teaching methods. Consequently, teachers experience challenges related to lack of exposure to teach complex grades of able and progressed learners together. Among others, recommendations are made to policy makers that the Curriculum Assessment Policy Statement (CAPS) for EFAL be aligned with the needs of diverse learners. The EFAL teachers should also engage in a culture of reading and lifelong learning to empower themselves professionally in order to overcome challenges in the inclusive teaching of able and progressed learners who have barriers to learning the language. / Ka leano la ho fetisa baithuti leha ba sa atleha likolong tsa mathomo, le tse mahareng Africa Boroa, baithuti ba bangata ba fetela mokhahlelong oa thuto e phahameng ntle le bokhoni ba puo ea mantlha ea Senyesemane, puo ea ho ithuta le ho ruta.
