<p style="text-align: justify;">Learners bring prior knowledge to their learning environments. This prior knowledge is said to have an effect on how they encode and later retrieve new information learned. This research aimed at exploring ‘A’ level mathematics learners’ understanding of the determinant concept of 3×3 matrices. A problem-solving approach was used to determine learners' conceptions and errors made in calculating the determinant. To identify the conceptions; a paper and pencil test, learner interviews, and learner questionnaires were used. Ten learners participated in the research and purposive sampling was used to select learners who are doing the syllabus 6042/2 Zimbabwe School Examination Council (ZIMSEC). Data was analyzed qualitatively through an analysis of each learners' problem-solving performance where common themes were identified amongst the learners’ work. Results from the themes showed that Advanced level learners faced some challenges in calculating the determinant of 3×3 matrices. Learners were having challenges with the place signs used in 3×3 matrices, especially when using the method of cofactors. The findings reveal that learners had low levels of engagement with the concepts and the abstract nature of the concepts was the major source of these challenges. The study recommends that; teachers should engage learners for lifelong learning and apply some mathematical definitions in real-world problems. Teachers should address the issues raised in this research during the teaching and learning process. In addition, teachers should engage learners more through seminars where learners get to mingle with others from other schools.</p>

This article aims to describe how is the process of decision making. Decision making is something that is never separated from human life, both simple decision making and complex problems. Everyone is always faced with the choice to take a decision. To be able to take the right decisions, every person should know the steps. This article presents what the decision-making steps and what is the importance of creative thinking in decision making. Creative thinking will help decision makers to improve the quality and effectiveness of problem solving and decision making results were made. In relation to the process of decision making, creative thinking is needed, especially in identifying problems and develop alternative solutions. The methodology used to arrange this article is Systematic Literature Review (SLR). First, researcher find relevant theories, and then make a conclusion about it, then analyzing, and finally make a new information based researcher analyzing.

Significant investments are being made in the application of new information and communications technologies (ICT) to teaching and learning in higher education. However, until recently, there has been little progress in devising an integrated costbenefit model that decision-makers can use to appraise ICT investment options from the wider institutional perspective. This paper describes and illustrates a model that has been developed to enable evaluations of the costs and benefits of the use of ICT. The strengths and limitations of the model are highlighted and discussed DOI:10.1080/0968776030110205

The innovations that happen in education seek for great leaders and with an outstanding professional background. The innovation managers are very open-minded to the changes that occur in schools, but unfortunately there are many of them who are closed to such changes in schools, the reason to resist is the lack of knowledge towards these educational innovations and of the changes that could be made in the schools and in the classrooms. Avoiding such problems could be made through active participation of the teachers in trainings, because the development of the technology and the improvement of the educational technology influences many changes in teaching methods and forms. Based on previous research it was seen that the role of multimedia in the classroom influences a great interest in participating actively in learning. This research was chosen intentionally with the reason of playing a positive role in raising the awareness of the community, with the argumentation of the hypothesis that multimedia in the learning process has a great role in purifying students with new information. Education, as a rule, slowly accepts any implementation of innovations in comparison with business, producing, transportation etcetera. In addition to it, implementing multimedia systems, distance learning, virtual schools etcetera would definitely increase the activity of the students in advancing their skills in comparison with their former background knowledge.

SummarySerial quantitative immunoelectrophoretic (IE) measurements of antithrombin III heparin cofactor (AT III) were made in groups of well and sick newborn infants classified by gestational age. Collection methods (venous vs. capillary) did not influence the results; serum IE measurements were comparable to AT III activity by a clotting method. AT III is gestational age-dependent, increasing from 28.7% of normal adult values at 28-32 weeks to 50.9% at 37-40 weeks, and shows a gradual increase to term infant levels (57.4%) by 3-4 weeks of age. Infants with the respiratory distress syndrome (RDS) show lower levels of AT III in the 33-36 week group, 22% vs. 44% and in the 37-40 week group, 33.6% vs. 50.9%, than prematures without RDS. Infants of 28-32 week gestational age had only slight differences, RDS = 24%, non-RDS = 28.7%. The lowest levels of AT III were seen in patients with RDS complicated by disseminated intravascular coagulation and those with necrotizing enterocolitis. Crossed IE on representative infants displayed a consistent pattern which was identical to adult controls except for appropriate decreases in the amplitude of the peaks. The thrombotic complications seen in the sick preterm infant may be related to the low levels of AT III.

<p>This study observed how two hypertext features – absence of a linear or author-specified order and availability of multiple reading aids – influence reading comprehension processes of ESL readers. Studies with native or highly proficient users of English, have suggested that readers reading hypertexts comprehend better than readers reading print texts. This was attributed to (i) presence of hyperlinks that provide access to additional information that can potentially help overcome comprehension obstacles and (ii) the absence of an author-imposed reading order that helps readers exercise cognitive flexibility. An aspect that remains largely un-researched is how well readers with low language competence comprehend hypertexts. This research sought to initiate research in the area by exploring the question: Do all ESL readers comprehend a hypertext better than a print text?</p> <p>Keeping in mind the fact that a majority of readers reading online texts in English can be hindered by three types of comprehension deficits – low levels of language proficiency, non-availability of prior knowledge, or both – this study investigated how two characteristic features of hypertext, viz., linking to additional information and non-linearity in presentation of information, affect reading comprehension of ESL readers. </p> <p>Two types of texts that occur in the electronic medium – linear or pre-structured texts and non-linear or self-navigating texts, were used in this study. Based on a comparison of subjects’ comprehension outcomes and free recalls, text factors and reader factors that can influence hypertext reading comprehension of ESL readers are identified. </p> Contradictory to what many researchers believe, results indicate that self-navigating hypertexts might not promote deep comprehension in all ESL readers.
