The paper attempts to throw light on the direct (instructional) cost of OU teaching methods as against conventional “live” instruction. The variable cost per student-course is with one exception lower in the OU than elsewhere. This constitutes a strong case for the use of existing OU packages in campus universities, especially as campus universities might feel able to dispense with the costs of the summer schools. It also constitutes a case for expansion of existing courses at the OU. As regards the development of new OU packages, the paper shows the Foundation courses to be much cheaper than equivalent provision de novo at the same scale in campus universities. Measured by the breakeven number of students, second-level courses in a given faculty are cheaper than foundation level courses. But they also have fewer students and some are operating at levels which, if there were no interdependence between courses, might be considered expensive. If however they were used by more students either at the OU or at campus universities they could be economic, even when taken on their own. The paper does not cost student time but, if this is cheaper when OU teaching methods are used, this is a further argument in their favour.
AbstractThis yearlong study explores how digital technologies are used during literacy instruction in the critical year of third grade. We analyzed technology use in 16 classrooms across six geographically and socioeconomically diverse schools. We examined the multiple layers of technology’s influences on teachers’ instructional decision-making and on students’ engagement. Applying Bloom’s Revised Taxonomy alongside the SAMR model, expectations for student technology use varied across settings and resulted in mixed levels of student engagement. Although technology has the potential to transform teaching and learning, it is most often used as a substitution for traditional instructional tools and to support students’ remembering and understanding rather than more complex tasks. Analysis suggests technology tools are not being strategically employed to support the development of 21st century learning skills. 相似文献
This research investigated the sources of explanations and understanding of natural phenomena in terms of the students’ cultural and school science experiences. The first phase involved interviews with eight village elders that probed their explanations and understanding of natural phenomena. The second phase involved the design, development and administration of two questionnaires on natural phenomena to 179 students in a rural boarding high school in Papua New Guinea (PNG). Most village elders gave explanations of many of the phenomena in terms of spirits, spells, magic, religion, and personal experiences. Most school-aged students choose scientific explanations of natural phenomena in terms of what they had learned in school or from personal experiences. However, many choose explanations of the same phenomena about spirits, spells and magic that came from the village, family or home. The study revealed that students’ ideas about natural phenomena are strongly governed and controlled by their school science knowledge in the school setting. It is likely that their own traditional knowledge cannot be identified in a school setting but that questionnaires in the students’ local language be given to students in their villages (as opposed to school). In addition, so as not to diminish the value of this traditional knowledge, science education programs are needed that are able to consider and harmonise traditional knowledge with school science. 相似文献
This paper presents the concept of critical flexibility as an alternative to eclecticism in instructional design. Eclecticism is often viewed as a persuasive alternative to theoretical
orthodoxy (i.e., rigid use of a single perspective or process) due to the openness and flexibility it purports to offer. In
contrast, the authors argue that eclecticism ignores or discourages critical reflection regarding background understanding
(e.g., implicit assumptions and values) and perpetuates the lack of openness and flexibility commonly associated with orthodoxy.
Critical flexibility, as an alternative to eclecticism, emphasizes an awareness of background understanding, but construes
it as capable of being explicated, critically examined, adjusted in specific contexts, and refined or developed over time
to facilitate increasingly flexible and effective design practices. The authors clarify the nature of critical flexibility
as a general way of being involved in the design process, suggest how it helps overcome the traditional theory–practice split,
and discuss several of its implications for scholarship and training. 相似文献
Treatments that interfere with animals’ short-term retention (e.g., in delayed matching-to-sample) were studied using a spatial memory task. Rats performed in an eight-arm radial maze in which choosing each arm without repetition was the optimal behavior. Performances were interrupted between fourth and fifth choices for a delay of 15 sec to 2 min. A variety of events occurring during the delay interval did not disrupt memories for prior choices (as assessed by the accuracy of postdelay choices). The ineffective treatments included variations in visual and auditory environments, removal from the maze, food consumed during the delay, a distinctive odor added to the maze, or combinations of these manipulations. Additionally, performance on another spatial task (a four-arm maze) during the delay between Choices 4 and 5 did not interfere with performance in the eight-arm maze. These findings suggest that rats’ memories for spatial locations are immune to retroactive interference, at least within the range of conditions reported, and that the rat can successfully segregate memories for spatial locations established in different contexts. 相似文献
Various initiatives over the past 40 years have aimed to strengthen children’s early learning and social development. One policy theory—manifest in recent welfare reforms—postulates that requiring single mothers to work more outside the home will advance children’s well-being. We first examine whether young children’s social development is related to maternal employment among 405 women who entered welfare-to-work programs in 1998. For girls, age 24–42 months, we found that their mother’s recent employment duration was significantly associated with a lower incidence of aggressive behavior and inattentiveness, measured by two scales from the Child Behavior Checklist (CBCL 2/3). Yet these relationships with employment were weaker than more robust associations observed for proximal child-rearing practices, including the frequency of reading with the child, enforcing a regular bedtime, the propensity to spank the child, as well as levels of maternal depression. We then assess whether broader measures of the mother’s economic security help to predict these proximal determinants of development. We observed that food security and indicators of job quality consistently predicted the proximal factors. Structural equation models (SEM) provided additional evidence that these broader indicators of economic security, but not recent employment per se, operated through parenting practices and maternal depression to influence girls’ and boys’ social development. These results are consistent with recent findings from random-assignment experiments, showing that employment gains rarely affect child outcomes unless mothers’ income and broader economic security also improve. 相似文献
This explanatory sequential mixed methods study investigated the writing feedback perceptions of middle and high school students (N = 598). The predictive and mediational roles of writing self-efficacy and perceptions of writing feedback on student writing self-regulation aptitude were examined using mediation regression analysis. To augment the quantitative findings, the explanations students provided for either liking or disliking writing feedback were explored using open-ended questions. Quantitative findings revealed that students’ perceptions of the feedback they receive about their writing partially mediated the relationship between writing self-efficacy and writing self-regulation aptitude. Qualitative data suggested ways in which students perceive writing feedback—both positive and negative. Collectively, the quantitative and qualitative data illustrate the influential role writing feedback perceptions plays in middle and high school student writing motivation and self-regulation beliefs. 相似文献
Using participatory action research (PAR), this paper explores the ethical practice of students engaged in practitioner research in a higher education context. Using narrative enquiry, the paper explores the participants’ experiences of practitioner research, including ethical dilemmas that resulted from a conflict of values between the practitioner and research roles. We postulate a multi-dimensional approach to ethical practice known as ‘ethical posture’ emerging from our consideration of conceptions of inquiry that resulted in contrasting ethical behaviour. 相似文献
