ABSTRACTModel-based instruction offers numerous benefits to students, including increased content knowledge and critical thinking. This study explored the differences in the knowledge outcomes and reasoning processes employed by undergraduate students in an introductory biology lab as they constructed, revised, and simulated a computational model of a prokaryotic gene regulatory system. We analysed post-lesson conceptual models (n?=?335) and audio-recorded small group discussions (n?=?10) of students that either constructed and revised a computational model and then investigated a pre-constructed computational model or only investigated a pre-constructed computational model to determine the impact of constructing and revising a computational model. No significant differences were found between the mental models of students who constructed and revised a computational model and those who only simulated a pre-constructed computational model. However, this study demonstrated that constructing and revising a model before simulating it offered additional benefits to students by fostering deeper cognitive reasoning processes. Constructing and revising a model elicited more explanatory and evaluative reasoning and prompted students to discuss the underlying mechanisms of the biological system. 相似文献

Submicrorepresentations (SMRs) are a powerful tool for identifying misconceptions of chemical concepts and for generating proper mental models of chemical phenomena in students’ long‐term memory during chemical education. The main purpose of the study was to determine which independent variables (gender, formal reasoning abilities, visualization abilities, and intrinsic motivation for learning chemistry) have the maximum influence on students’ reading and drawing SMRs. A total of 386 secondary school students (aged 16.3 years) participated in the study. The instruments used in the study were: test of Chemical Knowledge, Test of Logical Thinking, two tests of visualization abilities Patterns and Rotations, and questionnaire on Intrinsic Motivation for Learning Science. The results show moderate, but statistically significant correlations between students’ intrinsic motivation, formal reasoning abilities and chemical knowledge at submicroscopic level based on reading and drawing SMRs. Visualization abilities are not statistically significantly correlated with students’ success on items that comprise reading or drawing SMRs. It can be also concluded that there is a statistically significant difference between male and female students in solving problems that include reading or drawing SMRs. Based on these statistical results and content analysis of the sample problems, several educational strategies can be implemented for students to develop adequate mental models of chemical concepts on all three levels of representations. 相似文献

ABSTRACTAn increase in the number of children with speech–language pathology also having a genetic disorder imposes the need for speech and language pathologists (SLPs) to have sufficient knowledge about genetic basis of speech–language disorders. Research aim was to estimate in Serbian SLPs different aspects of theoretical and practical knowledge about intercorrelation of genetics and speech and language pathology and to compare obtained results with the results of SLPs in the United States. The questionnaire from Tramontana’s study was used in our study. Comparison of the results that obtained in our study with those in Tramontana’s study has shown that our study respondents have higher General Knowledge Index (78.6%: 66.2%), higher mean confidence summary score (22.2: 16.7) and higher mean score of ‘overall’ attitudes about genetics and its relation with communication disorders (20.8: 13.6). Differences which emerge from educational programmes, educational levels and practical experience in the observed groups are indicated as possible causes of differences in the obtained results. On the basis of the obtained results, it may be concluded that it is necessary to elevate SLPs’ level of general knowledge about genetics and to acquire their knowledge through clinical practice. 相似文献

ABSTRACTThe study aimed to investigate variations in addition and subtraction fluency by observing grade three students in Norway (n = 253, Mage = 8.38 y.) and Finland (n = 209, Mage = 9.35 y.) while controlling for their age and non-verbal reasoning. Gender differences were also examined. The focus of the study was on the performance of the low-achieving (LA) students in comparison to the typically achieving (TA) group, not neglecting differences in how early educational support was organised across the two countries. Two-minute speed tests in both addition and subtraction within the 1–20 number range were used to assess fluency. The Finnish students outperformed students in the Norwegian sample both in addition and subtraction fluency. There were more Norwegian students in the LA group (i.e. performance at or below the 25th percentile) in both addition (37.9% vs. 20.1%) and subtraction (39.1% vs. 15.8%). In comparison to the TA students, the LA students made more errors and skipped over more arithmetic tasks in an attempt to solve them. Observed differences are discussed in relation to both country characteristics concerning early mathematics education and early educational support. 相似文献

Surveys have confirmed the ubiquity of aggression in schools, and verbal aggression is not an exception. The identification of teasing as a frequent form of verbal aggression is an indispensable step towards diminishing it. The purpose of this study was to investigate teasing among primary school students in Slovenia. The research showed that teasing is common in schools: the most usual forms of teasing refer to the students’ appearance, and the victims mostly report negative feelings after being teased. Most teasing was done to reciprocate, and the most frequent response to teasing was a verbal comeback. The research revealed some differences in teasing between students by sex and age and offers some useful implications for practice. 相似文献

This study investigated the cognitive processes involved in learning information presented in multimedia and text format using electroencephalographic (EEG) measures. Thirty-eight students (19 gifted, and 19 average) learned material presented with text (text); text, sound, and picture (picture); and text, sound and video (video), while their EEG was recorded. Alpha power, which is inversely related to mental effort, was analyzed. For thetext presentation, the alpha power measures showed higher amplitudes (less mental activity) over the occipital and temporal lobes, and less alpha power (higher mental activity) over the frontal lobes. The results support the assumption that thevideo andpicture presentations induced visualization strategies, whereas thetext presentation mainly generated processes related to verbal processing. The results further showed that gifted students displayed less mental activity during all three formats of presentation. These differences were especially pronounced for thevideo format. No gender-related differences in EEG patterns related to the format of presentation were observed. 相似文献

While several have written about the connection between life experience and learning, there is little in the literature that explicitly deals with how a particular life experience can become a significant learning experience for one person, but not another. This qualitative study examines the underlying structure of the significance of life‐experience learning. Open‐ended responses to a question about one's significant learning experiences were collected from 405 adults. In addition, 19 interviews were conducted to probe more deeply about individuals’ learning experiences and the significance they held for the learner. Findings suggest that for learning to be significant: (1) it must personally affect the learner, either by resulting in an expansion of skills, sense of self, or life perspective, or by precipitating a transformation; and (2) it must be subjectively valued by the learner. 相似文献

Recent advances in genetic engineering nowallow the design of programmable biologicalartifacts. Such programming may include usageconstraints that will alter the balance ofownership and control for biotechnologyproducts. Similar changes have been analyzedin the context of digital content managementsystems, and while this previous work is usefulin analyzing issues related to biologicalprogramming, the latter technology presents new conceptual problems that require morecomprehensive evaluation of the interplaybetween law and technologically embeddedvalues. In particular, the ability to embedcontractual terms in technological artifactsnow requires a re-examination of disclosure andconsent in transactions involving such artifacts. 相似文献
