Flipped classrooms represent a new instructional paradigm for presenting K-12 instruction. Whereas in traditional classrooms new content is taught during the school day and application activities are assigned for homework, in flipped classrooms students are expected to acquire new content by working through assigned tasks at home prior to the next day’s class. Subsequently, class time is used for application activities. To date, limited, conflicting analyses of research about the efficacy of the flipped classroom paradigm have been reported. This lack of a clear consensus is of concern for students with serious learning and/or behavioural challenges who have not been the focus of these analyses and whose learning characteristics arguably run counter to what students must do to be successful in flipped classrooms. The investigation reported herein addresses one aspect of the aforementioned void in the literature. Data from an international survey of teacher educators from 33 countries that ascertained their thoughts about the appropriateness of the flipped classroom paradigm for students with serious learning and/or behavioural challenges are reported. Results indicate that teacher educators have reservations about the appropriateness of flipped classrooms, but that their opinions are not fully informed by knowledge about, and experience with, these classrooms.  相似文献

The purpose of this review was to identify the different augmented reality (AR) modalities used to teach anatomy to students, health professional trainees, and surgeons, and to examine the assessment tools used to evaluate the performance of various AR modalities. A scoping review of four databases was performed using variations of: (1) AR, (2) medical or anatomical teaching/education/training, and (3) anatomy or radiology or cadaver. Scientific articles were identified and screened for the inclusion and exclusion criteria as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses with extension for scoping reviews guidelines. Virtual reality was an exclusion criterion. From this scoping review, data were extracted from a total of 54 articles and the following four AR modalities were identified: head-mounted display, projection, instrument and screen, and mobile device. The usability, feasibility, and acceptability of these AR modalities were evaluated using a variety of quantitative and qualitative assessment tools. Within more recent years of AR integration into anatomy education, the assessment of visuospatial ability, cognitive load, time on task, and increasing academic achievement outcomes are variables of interest, which continue to warrant more exploration. Sufficiently powered studies using validated assessment tools must be conducted to better understand the role of AR in anatomical education.  相似文献

This paper compares the results of three surveys. The subjects comprise 96 adolescents in an English comprehensive school, 118 Arab adolescents in three schools in Israel and 89 adolescents in two schools in Saudi Arabia. The first and last groups of subjects have a modal age of 14 years whereas the majority of the second group are 15 years of age. The open‐ended questionnaire comprised 10 prompts designed to elicit responses concerning ideals and least ideals, most and least preferred companions, use of solitude, summum bonum, most and least desired outcomes to life and nascent philosophies. Two methods of analysis were used. First, references to dominant themes were totalled; secondly, responses were assigned to six categories according to the dominant values expressed from materialistic to altruistic. Similarities but also significant differences were found in the dominant themes and significant differences were also apparent in the values that were expressed. Most marked was the high value placed on parents and friendship by the English young people, the importance attached to education by the Israeli‐Arab group and the prominence given to Islam by the Saudi Arabian adolescents.  相似文献

Chlorella vulgaris (CV) has been reported to have antioxidant and anticancer properties. We evaluated the effect of CV on apoptotic regulator protein expression in liver cancer-induced rats. Male Wistar rats (200∼250 g) were divided into eight groups: control group (normal diet), CDE group (choline deficient diet supplemented with ethionine in drinking water to induce hepatocarcinogenesis), CV groups with three different doses of CV (50, 150, and 300 mg/kg body weight), and CDE groups treated with different doses of CV (50, 150, and 300 mg/kg body weight). Rats were sacrificed at various weeks and liver tissues were embedded in paraffin blocks for immunohistochemistry studies. CV, at increasing doses, decreased the expression of anti-apoptotic protein, Bcl-2, but increased the expression of pro-apoptotic protein, caspase 8, in CDE rats, which was correlated with decreased hepatoctyes proliferation and increased apoptosis as determined by bromodeoxy-uridine (BrdU) labeling and terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling (TUNEL) assay, respectively. Our study shows that CV has definite chemopreventive effect by inducing apoptosis via decreasing the expression of Bcl-2 and increasing the expression of caspase 8 in hepatocarcinogenesis-induced rats.

Uncertainty tolerance, individuals' perceptions/responses to uncertain stimuli, is increasingly recognized as critical to effective healthcare practice. While the Covid-19 pandemic generated collective uncertainty, healthcare-related uncertainty is omnipresent. Correspondingly, there is increasing focus on uncertainty tolerance as a health professional graduate “competency,” and a concomitant interest in identifying pedagogy fostering learners' uncertainty tolerance. Despite these calls, practical guidelines for educators are lacking. There is some initial evidence that anatomy education can foster medical students' uncertainty tolerance (e.g., anatomical variation and dissection novelty), however, there remains a knowledge gap regarding robust curriculum-wide uncertainty tolerance teaching strategies. Drawing upon humanities, arts and social sciences (HASS) educators' established uncertainty tolerance pedagogies, this study sought to learn from HASS academics' experiences with, and teaching practices related to, uncertainty pedagogy using a qualitative, exploratory study design. Framework analysis was undertaken using an abductive approach, wherein researchers oscillate between inductive and deductive coding (comparing to the uncertainty tolerance conceptual model). During this analysis, the authors analyzed ~386 min of data from purposively sampled HASS academics' (n = 14) discussions to address the following research questions: (1) What teaching practices do HASS academics' perceive as impacting learners' uncertainty tolerance, and (2) How do HASS academics execute these teaching practices? The results extend current understanding of the moderating effects of education on uncertainty tolerance and supports prior findings that the anatomy learning environment is ripe for supporting learner uncertainty tolerance development. This study adds to growing literature on the powerful moderating effect education has on uncertainty tolerance and proposes translation of HASS uncertainty tolerance teaching practices to enhance anatomy education.  相似文献

This study problematises the discourses of Pakistan's national curriculum textbooks to investigate how they represent Pakistan's indigenous languages/cultures through the prism of religion to constitute secondary school students' particular postcolonial linguistic identities. It also draws on the perspectives of 12 teachers and 424 students to record their responses. Taking insights from Paulo Freire's cultural invasion, Robert Blauner's internal colonisation and selected postcolonial perspectives, the study notes a dynamic interplay of the sampled textbooks, schoolteachers and the school as a site of discursive social practices. Jointly, they position students within an exclusionary homogenous Urdu-loving group—a language which is represented as Arabic's tributary. Indigenous languages are recognised, however, as an adjunct to Arabic and Urdu, emphasising their role in the proselytisation of Islam in the region. Similarly, fine arts and indigenous cultural festivals are represented from a particular religious lens. The students strongly identify with this curious case of internal colonisation and cultural invasion, and support it. They exhibit self-righteousness and aversion towards linguistic/cultural pluralism and minorities, which entails implications for Pakistan's national cohesion and educational parlance of equity and inclusivity.  相似文献

Detection of PCV2 DNA by SYBR Green I-based quantitative PCR   总被引:5,自引:0,他引:5  
We developed an assay for the detection and quantitation of porcine circovirus type 2 (PCV2) with the SYBR Green I-based real-time PCR. The real-time PCR provides a broad dynamic range, detecting from 103 to 1011 copies of DNA per reaction. No cross-reactions were found in specimens containing PCV1. Because of the high sensitivity and specificity of the assay with a relatively rapid and simple procedure, real-time PCR can be used as a routine assay for the clinical diagnosis of PCV2 infection. In this study we applied real-time PCR assay to 80 clinical samples, collected from 40 pigs with postweaning multisystemic wasting syndrome (PMWS) and 40 healthy pigs in comparison with conventional PCR assay. In 56 of 80 samples, PCV2 DNA was de-tected by conventional PCR assay. All samples positive for PCV2 DNA in conventional PCR assay were also positive in real-time assay, and 12 of 24 samples that tested negative for PCV2 DNA in the conventional assay were tested positive in real-time PCR assay. Real-time PCR assay increased the number of samples in which PCV2 was detected by 15%. It is, therefore, considered to be a useful tool for the detection of PCV2.  相似文献
