This yearlong study was implemented in seventh-grade life science classes with the students' regular teacher serving as teacher/researcher. In the study, a method of scoring concept maps was developed to assess knowledge and comprehension levels of science achievement. By linking scoring of concept maps to instructional objectives, scores were based upon the correctness of propositions. High correlations between the concept map scores and unit multiple choice tests provided strong evidence of the content validity of the map scores. Similarly, correlations between map scores and state criterion-referenced and national norm-referenced standardized tests were indicators of high concurrent validity. The approach to concept map scoring in the study represents a distinct departure from traditional methods that focus on characteristics such as hierarchy and branching. A large body of research has demonstrated the utility of such methods in the assessment of higher-level learning outcomes. The results of the study suggest that a concept map might be used in assessing declarative and procedural knowledge, both of which have a place in the science classroom. One important implication of these results is that science curriculum and its corresponding assessment need not be dichotomized into knowledge/comprehension versus higher-order outcomes. © 1998 John Wiley & Sons, Inc.

The psychometric characteristics and practicality of concept mapping as a technique for classroom assessment were evaluated. Subjects received 90 min of training in concept mapping techniques and were given a list of terms and asked to produce a concept map. The list of terms was from a course in which they were enrolled. The maps were scored by pairs of graduate students, each pair using one of six different scoring methods. The score reliability of the six scoring methods ranged from r = .23 to r = .76. The highest score reliability was found for the method based on the evaluation of separate propositions represented. Correlations of map scores with a measure of the concept maps' similarity to a master map provided evidence supporting the validity of five of the six scoring methods. The times required to provide training in concept mapping, produce concepts, and score concept maps were compatible with the adoption of concept mapping as classroom assessment technique. © 1999 John Wiley & Sons, Inc.

Concept mapping is a technique that paves the way to represent knowledge schematically. In this research, concept mapping was used as an assessment method on the impulse–momentum topic. The purpose of this study was to determine teacher candidates’ knowledge about understanding of the concepts of impulse and momentum by comparing and contrasting two different methods; namely, students’ concept maps and an achievement test. The mean of teacher candidates’ concept map scores are extremely low when compared with the scores of the achievement test. In addition, it was seen that although a great number of concepts were written down, not many relationships were established between these concepts. There is a weak correlation between the achievement test and the concept map scores since concept maps assess the students’ knowledge from a conceptual perspective while the achievement tests measure the level of students’ knowledge on the topic and his/her ability to apply this knowledge on different occasions.  相似文献

Long-term effects of a teacher education program on beginning teachers' cognitive structures for classroom management, and relationships between various measures of cognitive structure were investigated. Nine elementary teachers completed an ordered tree and a concept mapping exercise of the domain classroom management one year after program completion. Comparisons of follow-up data with exit scores revealed a positive but non-significant trend toward greater organization. Correlations between the ordered tree and scores derived from concept maps revealed significant relationships between the ordered tree and the scoring procedure of Roehler, Duffy, Conley, Hermann, Johnson, and Michelson (1990). Implications for the measurement of cognitive change in teacher education students are discussed.  相似文献

This paper explains the application of concept mapping to help foster a learning-centred approach. It investigates how concept maps are used to measure the change in learning following a two-week intensive undergraduate Marketing Principles course delivered to 162 Chinese students undertaking a Bachelor of Business Administration programme in China. Using four scoring procedures (breadth of knowledge, relational quality, structural quality and holistic quality), student learning is assessed in terms of prior and new knowledge, as well as improvement in knowledge structure. Concept map scores are correlated with conventional measures of overall student performance. The results provide strong evidence for improvement in students’ ability to externalise new learned concepts resulting from intensive instruction. Incorporating concept maps as a contemporary method of learning in the curriculum potentially enriches student learning, provides a measure of the impact of teaching on students’ learning and adds value to students’ higher education experience.  相似文献

The search for new, authentic science assessments of what students know and can do is well under way. This has unearthed measures of students' hands-on performance in carrying out science investigations, and has been expanded to discover more or less direct measures of students' knowledge structures. One potential finding is concept mapping, the focus of this review. A concept map is a graph consisting of nodes representing concepts and labeled lines denoting the relation between a pair of nodes. A student's concept map is interpreted as representing important aspects of the organization of concepts in his or her memory (cognitive structure). In this article we characterize a concept map used as an assessment tool as: (a) a task that elicits evidence bearing on a student's knowledge structure in a domain, (b) a format for the student's response, and (c) a scoring system by which the student's concept map can be evaluated accurately and consistently. Based on this definition, multiple concept-mapping techniques were found from the myriad of task, response format, and scoring system variations identified in the literature. Moreover, little attention has been paid to the reliability and validity of these variations. The review led us to arrive at the following conclusions: (a) an integrative working cognitive theory is needed to begin to limit this variation in concept-mapping techniques for assessment purposes; (b) before concept maps are used for assessment and before map scores are reported to teachers, students, the public, and policy makers, research needs to provide reliability and validity information on the effect of different mapping techniques; and (c) research on students' facility in using concept maps, on training techniques, and on the effect on teaching is needed if concept map assessments are to be used in classrooms and in large-scale accountability systems. © 1996 John Wiley & Sons, Inc.  相似文献

We examined whether different word displays also differ in terms of the format in which they are represented in memory. Undergraduates studied a text, an outline, a graphic organizer, or a concept map and then were shown either a verbal (digits) or spatial (dots) display. They were then tested on comprehension of the first display and recognition of the second display. Comprehending graphic organizers and concept maps interfered with the spatial concurrent task and vice versa, whereas the verbal concurrent task interfered with comprehension of texts and outlines. These results are consistent with the conjoint retention hypothesis suggesting that spatial encoding may explain the facilitative effects of graphic organizers and concept maps.  相似文献

In this study, we investigated the value of a concept map marking guide as an alternative formative assessment tool for science teachers to adopt for the topic of energy. Eight high school science teachers marked students’ concept maps using an itemized holistic marking guide. Their marking was compared with the researchers’ marking and the scores of a multiple-choice diagnostic test. Statistical analysis revealed that teachers evaluated students’ concept maps consistently, but the concept map scores were only mildly correlated with the multiple-choice test scores. We explored what each assessment method revealed in terms of students’ understanding with one student’s performance as a showcase. Teachers’ views on using the marking guide of concept maps as an assessment tool were also included. We discuss the value of the concept map marking guide as a formative assessment tool for science teachers to create and modify in order to encourage students’ conceptual learning.  相似文献

The benefits of using a comprehensive annotation strategy (employing underlining/circling, making connections, asking questions, and making comments) with knowledge maps (spatial/verbal arrays) and traditional, linear text to improve free recall scores for learners with individual differences in vocabulary and comprehension ability were examined. Types and frequencies of annotations generated were also examined for each stimulus format condition. Multiple regression analyses indicate that the frequency of use of two component annotation strategies, asking questions and making connections, were significant predictors of recall scores, while frequency of underlining/circling and generating elaborations failed to predict recall scores. Text users generated more underlining/circling, while knowledge map users generated more connections between ideas, suggesting that knowledge maps may facilitate the application of more productive annotation strategies. Also examined were the interrelationships between vocabulary ability, comprehension ability, and free recall scores.  相似文献

The purpose of this study was to examine relationships between structural characteristics of students' concept maps about chemical equilibrium and independent measures of their achievement in chemistry. Fifty students in 1991 and seventy students in 1992 completed a concept-mapping task using twenty-four specified concepts. Using similarities in concept map structure, based on the presence or absence of linked pairs of concepts, non-metric multidimensional scaling (MDS) was used to plot the location of the concept maps in coordinate space. The distribution of maps was based on differences in their structure, but also reflected levels of student achievement on independent tests. The relationship between the coordinate location of each student's maps and his or her test scores on independent chemistry achievement tests was sought by canonical correlation analysis of the 1991 data set. This revealed significant relationships between the MDS coordinates and test scores of recall of knowledge and its application. Multiple regression analysis of sixty-one students' maps from the 1992 data set against their percentile rank scores on a national chemistry quiz revealed significant relationships. The results are interpreted as revealing structural differences in conceptual organisation about chemical equilibrium among students with different levels of achievement and thus relative expertise in the domain. The significant relationship between map structure and cognitive process scores in chemistry also supports the view that the organisation of declarative knowledge influences its accessibility in cognitive tasks.  相似文献

After reviewing the uses made of concept maps in research, as an aid to instruction and as a form of assessment, the problems of scoring maps objectively are discussed. Maps created de novo by 15‐16 year‐old pupils, before and after their introduction to Mendelian genetics, are used to investigate the properties of a scoring system based on that developed by Novak et al. (1983). The maps have been scored separately for a number of features ('branching’, ‘general to specific’, ‘closed units’, ‘terminology’, ‘relationships’ and ‘ hierarchy ‘) and compared with performance on genetics examination‐type questions. The components are not all independent, and do not have strong relationships with performance. The limitations of analytic methods of scoring concept maps are discussed.  相似文献

Recent research in teacher cognition has shown that concept maps, or ordered trees, are sensitive to differences in teacher experience and to change resulting from participation in academic courses. In the current study, we examined the usefulness of concepts maps for detecting differences in kindergarten teachers' theoretical orientation (whole language versus phonics), and we assessed the stability of their concept maps over time. Both the structure and content of teachers' concept maps were examined at three times across an academic year. Results revealed that content but not structure measures differentiated whole language from phonics teachers. Specifically, whole language teachers generated more nodes related to child affect and individual differences between children. Teachers' maps were quite stable structurally and moderately stable in terms of content. The results suggest that concept maps are useful as a measure of theoretical orientation and that both structure and content of concept maps should be considered in studies using the ordered tree technique. Directions for future research are discussed.  相似文献

Research has shown that many educators do not understand the terminology or displays used in test score reports and that measurement error is a particularly challenging concept. We investigated graphical and verbal methods of representing measurement error associated with individual student scores. We created four alternative score reports, each constituting an experimental condition, and randomly assigned them to research participants. We then compared comprehension and preferences across the four conditions. In our main study, we collected data from 148 teachers. For comparison, we studied 98 introductory psychology students. Although we did not detect statistically significant differences across conditions, we found that participants who reported greater comfort with statistics tended to have higher comprehension scores and tended to prefer more informative displays that included variable-width confidence bands for scores. Our data also yielded a wealth of information regarding existing misconceptions about measurement error and about score-reporting conventions.  相似文献

This study investigated how well 74 6th-grade science students represented text structures from a 900-word textbook chapter on soil conservation, given a concept map template with four superordinate terms and 24 unsorted concepts. Findings suggest students were more successful at classifying pre-selected terms under given superordinate categories than they were at fully identifying relevant concept sets and articulating three different relationship types between terms. No significant differences were noted in the mapping performance of students at different reading levels. About two-third of students indicated they enjoyed concept mapping and would prefer to both read and map rather than just read without mapping. Students also expressed a strong preference for mapping in pairs or small groups compared to mapping alone. Multiple recommendations are provided for improving the relational thinking of students tasked with concept mapping expository science texts, including bridging to more open-ended maps, embedding mapping in longer-term inquiry projects, and leveraging collaborative and tool-based scaffolds.  相似文献

This study examined variation in the organization of domain-specific knowledge by 50 Year-12 chemistry students and 4 chemistry teachers. The study used nonmetric multidimensional scaling (MDS) and the Pathfinder network-generating algorithm to investigate individual and group differences in student concepts maps about chemical equilibrium. MDS was used to represent the individual maps in two-dimensional space, based on the presence or absence of paired propositional links. The resulting separation between maps reflected degree of hierarchical structure, but also reflected independent measures of student achievement. Pathfinder was then used to produce semantic networks from pooled data from high and low achievement groups using proximity matrices derived from the frequencies of paired concepts. The network constructed from maps of higher achievers (coherence measure = 0.18, linked pairs = 294, and number of subjects = 32) showed greater coherence, more concordance in specific paired links, more important specific conceptual relationships, and greater hierarchical organization than did the network constructed from maps of lower achievers (coherence measure = 0.12, linked pairs = 552, and number of subjects = 22). These differences are interpreted in terms of qualitative variation in knowledge organization by two groups of individuals with different levels of relative expertise (as reflected in achievement scores) concerning the topic of chemical equilibrium. The results suggest that the technique of transforming paired links in concept maps into proximity matrices for input to multivariate analyses provides a suitable methodology for comparing and documenting changes in the organization and structure of conceptual knowledge within and between individual students.  相似文献

This paper reports the results of a study that compared two concept‐mapping techniques, one high‐directed, “fill‐in‐the‐map,” and one low‐directed, “construct‐a‐map‐from‐scratch.” We examined whether: (1) skeleton map scores were sensitive to the sample of nodes or linking lines to be filled in; (2) the two types of skeleton maps were equivalent; and (3) the two mapping techniques provided similar information about students' connected understanding. Results indicated that fill‐in‐the‐map scores were not sensitive to the sample of concepts or linking lines to be filled in. Nevertheless, the fill‐in‐the‐nodes and fill‐in‐the‐lines techniques were not equivalent forms of fill‐in‐the‐map. Finally, high‐directed and low‐directed maps led to different interpretations about students' knowledge structure. Whereas scores obtained under the high‐directed technique indicated that students' performance was close to the maximum possible, the scores obtained with the low‐directed technique revealed that students' knowledge was incomplete compared to a criterion map. We concluded that the construct‐a‐map technique better reflected differences among students' knowledge structure. © 2001 John Wiley & Sons, Inc. J Res Sci Teach 38: 260–278, 2001  相似文献

The purpose of this study was to examine how different scoring procedures affect interpretation of maze curriculum‐based measurements. Fall and spring data were collected from 199 students receiving supplemental reading instruction. Maze probes were scored first by counting all correct maze choices, followed by four scoring variations designed to reduce the effect of random guessing. Pearson's r correlation coefficients were calculated among scoring procedures and between maze scores and a standardized measure of reading. In addition, t tests were conducted to compare fall to spring growth for each scoring procedure. Results indicated that scores derived from the different procedures are highly correlated, demonstrate criterion‐related validity, and show fall‐to‐spring growth. Educators working with struggling readers may use any of the five scoring procedures to obtain technically sound scores.  相似文献

Abstract

The causal relationship between drama-based reading instruction and reading comprehension among 4th-grade students was examined. Cognitive theories related to the role of imagery in memory were used to develop a drama-based reading comprehension program. A randomized pretest-posttest control-group design was then employed to assess the impact of the drama-based instruction on students' test scores on the reading comprehension portion of the Iowa Tests of Basic Skills. Results suggest a direct causal link between drama-based instruction and improved reading comprehension.  相似文献
