Knowledge Construction and Information Seeking in Collaborative Learning / La construction des connaissances et la recherche d’information dans l’apprentissage collaboratif
pp. 1-21 |
This study aims to better understand the complex dynamics of knowledge construction and information seeking in a collaborative learning setting. A total of 34 graduate students who participated in a collaborative research project were asked to complete process surveys in the initiation, midpoint, and completion phases of the project. The process survey for this study comprised closed questions that sought to measure students’ perceptions of knowledge and difficulty as well as open-ended questions that asked students what they knew about the topic and what they considered difficult at each phase of the project. The results revealed growth in individual students’ knowledge as they proceeded through the project. When the results of this study are compared to findings from studies focusing on individual information seeking, students who participated in the collaborative research project began the project with confidence as they developed a shared understanding of the topic in the early phase of the project. However, students became more stressed as the project progressed as they carried out their information-seeking activities in individual ways.Cette étude a pour objectif de mieux comprendre la dynamique complexe de la construction des connaissances et de la recherche d’information dans la situation de l’apprentissage collaboratif. Nous avons demandé à trente-quatre étudiants des cycles supérieurs ayant participé à un projet de recherche collaborative de participer à une enquête sur le processus lors des phases de début, de milieu et de fin du projet. Aux fins de cette étude, l’enquête comprenait des questions fermées qui avaient pour but de mesurer les connaissances acquises ainsi que la difficulté telles que per?ues par les étudiants, et des questions ouvertes qui demandaient aux
étudiants ce qu’ils savaient sur le sujet et ce qu’ils considéraient comme difficile à chaque phase du projet. Les résultats ont montré une croissance des connaissances des élèves au fur et à mesure qu’ils avan?aient dans le projet. En comparant les résultats de cette étude avec les résultats d'études portant sur la recherche individuelle d’information, les étudiants ayant participé à un projet de recherche collaborative ont démarré le projet avec une confiance due au fait qu’ils avaient développé une compréhension commune de la question dès la première phase du projet. Toutefois, les étudiants ressentent plus de stress quand le projet avance et qu’ils doivent effectuer leurs activités de recherche d’information individuellement.

Annual analyses of the clinical materials of acute myocardial infarction patients admitted to a collaborative group of hospitals in Beijing demonstrated that there was a progressive lowering of hospital fatality from 27.5% before 1972 to 14.6% in 1976, and no further lowering since then. The relevant factors of low fatality were the efficacy in reducing shock and primary ventricular fibrillation which might be accounted for by the progress in the emergency case of AMI patients especially with regard to early diagnosis, early treatment and close monitoring. Factors such as sex, site of infarction, preexisting diseases and the time between the onset of symptoms and hospitalization were irrelevant.根据10年来临床资料的汇总分析,急性心肌梗塞8周内住院病死率有明显下降,1972年以前为27.5%,年为20.7～24.8%,年为11.1～14.6%,1976年以后没有进一步的下降。通过前后两阶段资料的对比分析,年病死率的下降,主要是并发休克与原发室颤的减少,这与早期诊断、治疗、进行监护有关;与患者性别、梗塞部位、伴发病及发病距入院时间无明显关系。 The results arising out of authors participating an inter-national collaborative study organized by 2nd AOHW in 1982 were reported, when HLA frequencies in 50 newly diagnosed NPC patients were compared with those in 40 normal controls, there is an increased risk of NPC associated with B17(RR=2.54) and a decreased with A11 (RR=0.28). On the other hand, there is an excess of DR double blanks among NPC patients, which are probably associated with increased risk of NPC (RR=2.82). Association between antigen... The results arising out of authors participating an inter-national collaborative study organized by 2nd AOHW in 1982 were reported, when HLA frequencies in 50 newly diagnosed NPC patients were compared with those in 40 normal controls, there is an increased risk of NPC associated with B17(RR=2.54) and a decreased with A11 (RR=0.28). On the other hand, there is an excess of DR double blanks among NPC patients, which are probably associated with increased risk of NPC (RR=2.82). Association between antigen BW46 and NPC has not been confirmed in this study. This may be attributable to the smaller size of the sample.本文报告作者参加1982年由第二届亚大地区组织相容性工作会议(2nd AOHW)组织的国际协作研究的结果。50名初诊鼻咽癌患者与40名正常对照者的HLA抗原频率比较,可见抗原B17与NPC的高风险性相关(RR=2.54),抗原A11与NPC的低风险性相关(RR=0.28),鼻咽癌患者的DR双空白增多也可能与NPC的高风险性相关(RR=2.82)。本研究未能证实抗原BW46与NPC的关联,可能归因于样本偏小。 A collaborative study to ascertain the mortality of cancer among coking plant workers was instituted in 1982 according to a joint program on the investigation of occupational cancer projected by the Ministry of Public Health, the Ministry of Metallurgical Industry, the Ministry of Chemical Industry, and the All-China Federation of Trade Unions.

A collaborative study to ascertain the mortality of cancer among coking plant workers was instituted in 1982 according to a joint program on the investigation of occupational cancer projected by the Ministry of Public Health, the Ministry of Metallurgical Industry, the Ministry of Chemical Industry, and the All-China Federation of Trade Unions. In this report discussion is limited to the methodology used in this study. A retrospective cohort study was conducted for the workers at nineteen coking plants in different parts of this country. The workers were categorized into six main work areas. The cancer mortality of the workers in each area and subdivision was compared with that of a population of workers at rough rolling mills in steel industries in different parts of this country. The standardized rate ratios (SRRs) from selected cancers were calculated. SRRs from lung cancer were calculated for six groups of the coke oven workers according to the latency (interval between the initial date of employment and the date of death) .按照卫生部、冶金部、化工部和中华全国总工会关于开展职业性肿瘤调查的联合通知,1982年进行了焦化厂工人的癌症死亡的协作调查研究。本文仅论及本研究用的方法。 对我国不同地区的19个焦化厂进行了回顾性队列研究。焦化厂被分为六大工作区。每一工作区和再分作业都与分布全国的钢铁企业中钢坯初轧厂职工人群进行癌症死亡比较,计算癌症的标化率比率(SRR)。并根据就业至观察终点的间隔年数(latency)把焦炉作业工人分为6组,计算各组的肺癌SRR。&nbsp&&&&&相关查询
