Inquiry learning environments increasingly incorporate modelling facilities for students to articulate their research hypotheses and (acquired) domain knowledge. This study compared performance success and scientific reasoning of university students with high prior knowledge (n = 11), students from senior high‐school (n = 10), and junior high‐school (n = 10) with intermediate and low prior knowledge, respectively, in order to reveal domain novices’ need for support in such environments. Results indicated that the scientific reasoning of both groups of high‐school students was comparable to that of the experts. As high‐school students achieved significantly lower performance success scores, their expert‐like behaviour was rather ineffective; qualitative analyses substantiated this conclusion. Based on these findings, implications for supporting domain novices in inquiry learning environments are advanced. 相似文献

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

It has been suggested that proportional reasoning tasks contain field effects. Field-dependent students are considered to be highly influenced by the structure of the perceptual field and lack an articulated conceptual framework. To test the hypothesis that there is a significant correlation between field independence and proportional reasoning tasks, a sample of science students were tested to determine performance in proportional reasoning and degree of field independence. It was found that even students who are normally capable of proportional reasoning can be misled by the presence of field effects. A significant correlation (r = 0.50; p = 0.001) was found between the test of field independence and the nine items of proportional reasoning. Educational implications are drawn. 相似文献

We developed a rubric for measuring students' ability to reason and write scientifically. The Rubric for Science Writing (Rubric) was tested in a variety of undergraduate biology laboratory courses (total n = 142 laboratory reports) using science graduate students (teaching assistants) as raters. Generalisability analysis indicates that the Rubric provides a reliable measure of students' abilities (g = 0.85) in these conditions. Comparison of student performance in various biology classes indicated that some scientific skills are more challenging for students to develop than others and identified a number of previously unappreciated gaps in the curriculum. Our findings suggest that use of the Rubric provides three major benefits in higher education: (1) to increase substance and consistency of grading within a course, particularly those staffed by multiple instructors or graduate teaching assistants; (2) to assess student achievement of scientific reasoning and writing skills; and (3) when used in multiple courses, to highlight gaps in alignment among course assignments and provide a common metric for assessing to what extent the curriculum is achieving programmatic goals. Lastly, biology graduate students reported that use of the Rubric facilitated their teaching and recommended that training on the Rubric be provided to all teaching assistants. 相似文献

Although electromagnetism is an important component of upper secondary school physics syllabuses in many countries, there has been relatively little research on students’ understanding of the topic. A written test consisting of 16 diagnostic questions was developed and used to survey the understanding of electromagnetism of upper secondary school students in Turkey (n = 120) and England (n = 152). A separate test consisting of 10 questions on the visualization of spatial rotation was used to investigate the hypothesis that students’ ability to visualize three‐dimensional situations from two‐dimensional representations might influence learning of electromagnetism. Many students’ responses showed misunderstandings and inconsistencies that suggested they did not have a coherent framework of ideas about electromagnetism. Common errors included confusing electric and magnetic field effects, seeing field lines as indicating a “flow”, using cause–effect reasoning in situations where it does not apply, and dealing with effects associated with the rate of change of a variable. Performance on the spatial rotation test was, however, only weakly correlated with performance on the electromagnetism questions. The findings suggest the need to develop teaching strategies that help students to visualize magnetic field patterns and effects, and assist them in integrating ideas into a more coherent framework. 相似文献

Research Findings: National policy today is on the brink of defining preschool experiences as essential for children’s academic success. Indeed, many children’s classroom experience begins as they transition from infant/toddler care to a preschool classroom. This study examined developmentally relevant skill domains among 36-month-olds (effortful control, social engagement, and language abilities) and tested their organization in a latent factor model of skills hypothesized to promote classroom adaptation. Assessments of low-income children interacting with a parent and examiner from the Early Head Start Research and Evaluation Project were utilized (n = 1,814). The data included observations of mother–child interactions during semistructured activities at home and child behavior assessments. Results indicated that the interrelated structure of children’s skills was best defined in a 2-factor, latent variable model: effortful control and social communication. These learning skills were related to but separate from general cognitive ability. Practice or Policy: Home-visiting programs for infants and toddlers are expected to promote children’s school readiness, yet little research has focused on the skills that facilitate children’s transition to the large-group learning environment at age 3. Implications of this model for early prevention efforts and early childhood teacher training to promote children’s readiness for group-based learning are discussed. 相似文献

The purpose of this research was to investigate the cognitive abilities that explain reading comprehension across childhood and early adulthood. Drawing from the standardization sample of the Woodcock–Johnson III, analyses were conducted with large samples at age levels spanning early childhood to early adulthood: 5 to 6 (n = 639), 7 to 8 (n = 720), 9 to 13 (n = 1,995), 14 to 19 (n = 1,615), and 20 to 39 (n = 1,409). Using a model including factors representing general intelligence, Cattell–Horn–Carroll broad abilities, and reading decoding skills, results revealed significant direct effects for reading decoding skills and Crystallized Intelligence on reading comprehension across all age levels. Memory‐related abilities, processing speed, and auditory processing demonstrated indirect effects on reading comprehension through reading decoding skills. The magnitude of direct and indirect effects varied as a function of age. The results provide support for integrative models of reading that include both direct and indirect effects of cognitive abilities on reading comprehension and for consideration of developmental differences in the cognitive aptitudes predicting reading comprehension. © 2012 Wiley Periodicals, Inc. 相似文献

This paper is about augmented reality (AR) and its potentials to support students in handling scientific representations. For this purpose, first representations are examined from a science educational and instructional psychology perspective. After giving a short overview of AR in general and how it can be delineated from virtual reality (VR), potential advantages of an educational use of AR are outlined considering typical difficulties of students when learning with scientific representations. Since literature frequently reports sex differences in spatial abilities, this study focuses on potential differential effects in the use of AR depending on sex. Against this background, AR might be a tool which can help to compensate for disadvantages in spatial abilities. In order to investigate this question, chemistry students had to answer 20 items related to stereochemistry, a concept that places high demands on mental spatial rotation skills. While one half of the items had to be solved using two-dimensional (2D) ball-and-stick figures of molecules, the other half had to be answered with the help of AR representations. Due to the aforementioned sex differences regarding visuo-spatial abilities between males and females found in the literature, it is hypothesized that AR representations will support all students but females in particular by reducing cognitive load. If this assumption is correct, the AR items would have to be correctly solved by the students more often than the 2D items. The results of analyses of variance indeed reveal a significant effect of the sex variable dependent on the type of representation. In addition, a questionnaire was administered to survey the students’ attitudes towards learning with the AR app used. 相似文献

The broad cognitive abilities defined by the Cattell–Horn–Carroll (CHC) theory have been shown to predict school achievement. However, the ecological validity of these constructs has not been studied in classroom settings. This study compares ratings by a sample of teachers (n = 53) and school psychologists (n = 86) of the importance of the CHC cognitive abilities in the classroom. The scale demonstrated adequate reliability (total scale α = .93, median α = .74), although evidence of construct validity varied between teachers and school psychologists. Both teachers and school psychologists rated quantitative ability, crystallized knowledge, and fluid reasoning as most important to school success. However, school psychologists rated short‐term memory and quantitative ability as more important than did the teachers. Importance of these differences for consultation is discussed. © 2009 Wiley Periodicals, Inc. 相似文献

The primary goal of this study was the broad assessment and modeling of scientific reasoning in elementary school age. One hundred fifty-five fourth graders were tested on 20 recently developed paper-and-pencil items tapping four different components of scientific reasoning (understanding the nature of science, understanding theories, designing experiments, and interpreting data). As confirmed by Rasch analyses, the scientific reasoning items formed a reliable scale. Model comparisons differentiated scientific reasoning as a separate construct from measures of intelligence and reading skills and revealed discriminant validity. Furthermore, we explored the relationship between scientific reasoning and the postulated prerequisites inhibitory control, spatial abilities and problem-solving skills. As shown by correlation and regression analyses, beside general cognitive abilities (intelligence, reading skills) problem-solving skills and spatial abilities predicted performance in scientific reasoning items and thus contributed to explaining individual differences in elementary school children's scientific reasoning competencies. 相似文献

Verbal and nonverbal forms of thinking exhibit widespread dissociation at neural and behavioral level. The importance of this for children's causal thinking and its implications for school science are largely unknown. Assessing 5‐ to 10‐year‐olds' responses (N = 231), verbal ability predicted causal reasoning, but only at lower levels, while nonverbal ability was the strongest predictor at higher levels of causal inference. We also distinguished between generic and scientific vocabulary use (n = 101). The results showed that use of scientific vocabulary predicted causal reasoning beyond generic, and connected more to nonverbal thinking. The findings highlighted the importance of elementary school science activities supporting application of nonverbal ability in thinking about causal processes; the benefits of linking nonverbal imagery to scientific vocabulary; and shortcomings in understanding of the forms/sources of nonverbal ability and their role in learning. 相似文献

ABSTRACTIntroductory undergraduate courses present an opportunity to use disciplinary concepts in solving authentic problems. Making complex natural systems accessible to students through computer-based models allows them to practice making evidence-based predictions and communicate understanding. Despite the importance of modelling tools in formal classrooms, gaps exist in our understanding of how post-secondary students engage in computer-based modelling. Introductory courses, particularly in the hydrosciences, typically do not use these tools. This mixed methods study examines students’ model-based reasoning about a water-related issue over two years in response to a flipped course model. Students in an introductory water course learned basic hydrologic content and used a computer-based water model to complete a project. Data came from a pre-/post-course assessment, student assignments, and student interviews. Results of quantitative and qualitative data analyses show that students in the revised version of the course (Year 2, n?=?53) increased their understanding of core hydrology concepts and performed better on their evaluation of a computer-based water model, than students in the initial course (Year 1, n?=?38). We tentatively attribute these observed changes to increased active learning opportunities surrounding computer-based modelling of water systems. Findings contribute to science literacy development, undergraduate science learning environment design, and undergraduate scientific modelling. 相似文献

“Complex systems” is a general-purpose reasoning scheme, used in a wide range of disciplines to make sense of systems with many similar entities. In this paper, we examine the generality of this approach in learning chemistry. Students' reasoning in chemistry in terms of emergent complex systems is explored for two curricula: a normative and a complexity-based one, so that the interaction could be examined under both the conditions. A quasi-experimental pretest-intervention-posttest comparison group design was used to explore student's learning, complemented with interview data. The experimental group (n = 47) studied the topic of gases with a complexity-based curriculum. A comparison group (n = 45) studied with a normative curriculum for the same duration. Students' answers to questionnaires were coded with a complexity-based approach that included levels (distinguishing micro- and macro-levels), stochastic particle behaviors, the emergence of macro-level patterns from micro-level behaviors, and the source of control in the system. It was found that students' reasoning about chemistry concepts in terms of complex systems falls into three distinct and coherent mental models. A sophisticated mental model included most of the above-described complexity features, while the nonsophisticated model included none. The intermediate model is typified by distinguishing between levels, but not by stochastic and emergent behaviors. The nonsophisticated mental model was used mostly in the pretest. In the posttest, the experimental group used the intermediate and sophisticated models; while the comparison group used the nonsophisticated and intermediate models. Discussion approaches the topics of the generality of the complex systems approach; and the unique forms of reasoning that a complexity approach may contribute to learning science. 相似文献

Currently, medical education context poses different challenges to anatomy, contributing to the introduction of new pedagogical approaches, such as computer-assisted learning (CAL). This approach provides insight into students' learning profiles and skills that enhance anatomy knowledge acquisition. To understand the influence of anatomy CAL on spatial abilities, a study was conducted. A total of 671 medical students attending Musculoskeletal (MA) and Cardiovascular Anatomy (CA) courses, were allocated to one of three groups (MA Group, CA Group, MA + CA Group). Students' pre-training and post-training spatial abilities were assessed through Mental Rotations Test (MRT), with scores ranging between 0-24. After CAL training sessions, students' spatial abilities performance improved (9.72 ± 4.79 vs. 17.05 ± 4.57, P < 0.001). Although male students in both MA Group and CA Group show better baseline spatial abilities, no sex differences were found after CAL training. The improvement in spatial abilities score between sessions (Delta MRT) was correlated with Musculoskeletal Anatomy training sessions in MA Group (r = 0.333, P < 0.001) and MA + CA Group (r = 0.342, P < 0.001), and with Cardiovascular Anatomy training sessions in CA Group (r = 0.461, P = 0.001) and MA + CA Group (r = 0.324, P = 0.001). Multiple linear regression models were used, considering the Delta MRT as dependent variable. An association of Delta MRT to the amount of CAL training and the baseline spatial abilities was observed. The results suggest that CAL training in anatomy has positive dose-dependent effect on spatial abilities. 相似文献

The purpose of this study was to examine the relations of various cognitive abilities and aspects of math performance with computational estimation skill among third graders. Students (n= 315) were assessed on language, nonverbal reasoning, concept formation, processing speed, long‐term memory, working memory, inattentive behavior, basic reading skill, arithmetic number combination skill, double‐digit computation skill, and computational estimation ability. One‐way analysis of variance indicated significant differences in estimation skill among students of low, average, and high math computation performance. The unique predictors of estimation skill were arithmetic number combination skill, nonverbal reasoning, concept formation, working memory, and inattentive behavior. 相似文献

Informal learning experiences have risen to the forefront of science education as being beneficial to students' learning. However, it is not clear in what ways such experiences may be beneficial to students; nor how informal learning experiences may interface with classroom science instruction. This study aims to acquire a better understanding of these issues by investigating one aspect of science learning, scientific reasoning ability, with respect to the students' informal learning experiences and classroom science instruction. Specifically, the purpose of this study was to investigate possible differences in students' scientific reasoning abilities relative to their informal learning environments (impoverished, enriched), classroom teaching experiences (non-inquiry, inquiry) and the interaction of these variables. The results of two-way ANOVAs indicated that informal learning environments and classroom science teaching procedures showed significant main effects on students' scientific reasoning abilities. Students with enriched informal learning environments had significantly higher scientific reasoning abilities compared to those with impoverished informal learning environments. Likewise, students in inquirybased science classrooms showed higher scientific reasoning abilities compared to those in non-inquiry science classrooms. There were no significant interaction effects. These results indicate the need for increased emphases on both informal learning opportunities and inquiry-based instruction in science. 相似文献

The purpose of this research is to investigate the determinants of student attrition in institutions of higher education. A causal model was developed which synthesized research findings on turnover in work organizations and on student attrition. Questionnaires were distributed to university freshmen (N = 1,171). The data was analyzed using multiple regression and path analysis. The regressions produced anR
2 = .36 for females and .27 for males. Findings indicate that three surrogate measures for pay were significantly related to intent to leave for both sexes and that the theories and determinants developed in research on turnover are useful in studies of student attrition.Paper presented at the Annual Meeting of American Educational Research Association, San Francisco, April 1979. 相似文献

The purpose of the present study was to explore the 3rd-grade cognitive predictors of 5th-grade computational skill with rational numbers and how those are similar to and different from the cognitive predictors of whole-number computational skill. Students (n = 688) were assessed on incoming whole-number calculation skill, language, nonverbal reasoning, concept formation, processing speed, and working memory in the fall of 3rd grade. Students were followed longitudinally and assessed on calculation skill with whole numbers and with rational numbers in the spring of 5th grade. The unique predictors of skill with whole-number computation were incoming whole-number calculation skill, nonverbal reasoning, concept formation, and working memory (numerical executive control). In addition to these cognitive abilities, language emerged as a unique predictor of rational-number computational skill. 相似文献
