Learning management systems (LMSs) are used by universities to support learning and teaching. Two-way communication and strong relationships can contribute to successful learning, however, LMSs are not generally viewed as an instrument to facilitate just that in an e-learning environment. The perceptions of lecturers and students on the eFundi LMS as communication and relationship building instrument was studied in this case bymeans of semistructured interviews and group-administered surveys. It was found that although students have a need for engaging in two-way communication with lecturers and costudents by means of the eFundi LMS and viewed it favourably as a relationship- building instrument, most lecturers did not make use of its interactive functionalities. Further research from a communication and relationship building perspective is therefore necessary to assure optimal LMS use in e-learning environments.

Attention is in particular being paid to the role of professional identity in how they applied innovative teaching methods such as enquiry-based teaching. The study is based on the personal narratives of the six teachers, regarding their own learning experiences in MST, the impact of their professional training at an institution of higher education, as well as their first experiences as MST teachers in the workplace. A qualitative research design was applied and data was obtained through visual (photo collages) and written stories, observation and interviews. Whilst all the teachers held negative attitudes towards Mathematics, this situation was turned around during their university training. The three teachers in early childhood education experienced their entrance to the profession as positive, due mainly to the support of colleagues in their application of innovative teaching methods. Two teachers in the foundation phase, however, experienced the opposite. The findings emphasise the complex processes in the moulding of a professional teacher identity and how teaching practices are influenced by these processes.","PeriodicalId":30428,"journal":{"name":"South African Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70517386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Cardio Stress Index (CSI) is a noninvasive marker of the stress that the heart is experiencing. The aim of the study was to test the physiological impact of 20 weeks of intense training of armed service recruits, using CSI as a noninvasive biomarker of cardiac stress. Armed service recruits are faced with many stressors, including a strenuous training regimen that may have an impact on their physiological functioning. The CSI is a noninvasive marker of the stress that the heart is experiencing. The calculation of the CSI is based on the duration of vascular excitation (QRS duration), heart rate, heart rhythm and standard deviation of the duration of time between each successive cardiac cycle (RR-interval). The aim of the present study was to test the physiological impact of 20 weeks of strenuous training of armed service recruits, using CSI as a noninvasive biomarker of cardiac stress. Experiments were conducted at three points in time (weeks 1, 12, 20) during the basic military training of armed service recruits ( n = 202, males = 115, females = 87), aged between 18 and 24 years. Variables measured include: Resting CSI, heart rate and blood pressure. Data analysis was performed, using paired t -tests for pairwise comparisons of week 1 (baseline) with week 12; week 12 with week 20; and week 1 with week 20. The average CSI and heart rate remained within normal values for male participants on all three testing occasions. However, baseline readings for females were significantly higher during week 1. There was an overall decrease in the CSI in the 20 week time frame. From this study it seems as if the CSI measurement is a noninvasive method to establish the effects of training on the health of the heart.","PeriodicalId":30428,"journal":{"name":"South African Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70516608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
