This paper reports on teachers' use of concept mapping as an alternative assessment strategy in advanced level biology classes and its effects on students' cognitive skills on selected biology concepts. Using a mixed methods approach, the study employed a pre-test/post-test quasi-experimental design involving 156 students and 8 teachers from intact classes. A researcher-constructed Biology Cognitive Skills Test was used to collect the quantitative data. Qualitative data were collected through interviews and students' personal documents. The data showed that the participants utilized concept mapping in various ways and they described positive experiences while being engaged in its use. The main challenge cited by teachers was the limited time available for more consistent use. The results showed that the use of concept mapping in advanced level biology can lead to learning gains that exceed those achieved in classes where mainly traditional methods are used. The students in the concept mapping experimental groups performed significantly better than their peers in the control group on both the lower-order (F(1)?=?21.508; p?<?.001) and higher-order (F(1)?=?42.842, p?<?.001) cognitive items of the biology test. A mean effect size of .56 was calculated representing the contribution of treatment to the students' performance on the test items. 相似文献

Knowledge structure is an important aspect for defining students’ competency in biology learning, but how knowledge structure is influenced by the teaching process in naturalistic biology classroom settings has scarcely been empirically investigated. In this study, 49 biology lessons in the teaching unit blood and circulatory system in 9th grade German classrooms were videotaped and analyzed. Before the lesson, a questionnaire was administered to the students to solicit their responses about learning motivation. After the lesson, students’ learning outcomes on knowledge structure were examined with the concept mapping method. The video coding used in this study focused on the knowledge linking levels during the biology lesson. Out of the 49 classes, those with the highest and those with the lowest linking levels were selected based on the coding results. In high-linking classes, interrelated facts were introduced more often in the lessons, whereas in the lessons of the low-linking classes, isolated pieces of knowledge were predominant. The results from the concept mapping task showed that the students in the high-linking classes constructed more correct relations among the concepts compared to the students in the low-linking classes. The results remained stable even after controlling for learning motivation. These findings confirm the importance of teaching interrelated facts and concepts instead of isolated facts for fostering students’ knowledge structure. As a result, based on the Bavarian biology curriculum, we develop materials and programs to enable students, student teachers, and teachers to focus on interrelated facts and basic concepts instead of isolated facts in biology lessons. 相似文献

This paper evaluates the effectiveness of concept maps as a teaching and learning tool in university level Principles of Microeconomics courses in Australia and USA. Concept mapping was incorporated in the teaching material in both courses at different countries and, at the end of the semester, the students completed a survey regarding the use, effectiveness, and accessibility of concept maps. It was revealed that USA students valued concept maps relatively less than Australian students. We provide two explanations: First, there may be differences in prior training in economic and/or concept mapping between Australian and USA students. Second, there were significant differences in class structure, which caused the link between collaborative study-groups and the construction of concept maps to not be maintained in the case of USA students. 相似文献

This paper compares the efficiency of calculus classes. Two kinds of classes are evaluated: the traditional ones and others that use computational methods in teaching. This experiment was performed at Fluminense Federal University, Niterói, Brazil, from 1998 to 2000. The emphasis of this paper is on the quantitative evaluation using two operational research tools: multicriteria decision aid methods (mainly using the MACBETH approach) and data envelopment analysis. The evaluating variables are the level at which students enter the university and the performance of the students after studying calculus. 相似文献

This paper examines the contention that achievement in research is a prerequisite for effective teaching in higher education. It also explores university level teaching more generally with the purpose of examining the links between teaching and research. Concept mapping, in particular, is described as a means of exploring both the knowledge structures of experts (teachers and researchers) and the cognitive changes that are indicative of meaningful learning among students. We use the approach to suggest that rich and complex networks are indicative of expert status, but that these are seldom made explicit to students in the course of teaching. Instead, simple, linear structures comprise most lesson plans or teaching sequences. This linearity is often made transparent through the lecturers’ use of PowerPoint presentations to structure teaching. Thus the transmission mode of teaching predominates in HE and evidence of authentic research‐led teaching remains scant. This is likely to reinforce surface learning outcomes among university students and be an impediment to the emergence of expert status. The linear chains that are commonly espoused in teaching lend themselves to rote learning strategies rather than to individual meaning making. The approach we describe here has the potential to reinstate expert status as the prime qualification for teaching in higher education. Where concept mapping is used to share and explore knowledge structures between students and experts, then learning can be shown to occur in ways that are synonymous with research and discovery. Using this approach, the teacher–student distinction becomes legitimately blurred so that the sharing and advancement of knowledge are concomitant. In conclusion, we suggest that this is a basis for a pedagogy that is appropriate to HE and distinct from the compulsory sector. 相似文献

Abstract All students learn more and are less likely to be off‐task when they are involved in actively making responses. The use of response cards is a cost‐effective and practical strategy to increase individual responding in whole class and group teaching with students from pre‐school to university level. It may be particularly useful in classes that include learners with learning or behaviour difficulties. Response cards may be pre‐printed, where students select a response, or may require students to write a brief response. The research shows that students make more responses with response cards, are less likely to be disruptive and score better on quiz and test results than they do with conventional oral questioning. 相似文献

The primary objective of this research was to compare various groups of Greek university students for their level of knowledge of Evolution by means of Natural Selection (ENS). For the purpose of the study, we used a well known questionnaire the Conceptual Inventory of Natural Selection (CINS) and 352 biology majors and non-majors students from the University of Athens took part in it. A principal components analysis revealed problems with the items designed to assess the concepts of population stability, differential survival and variation inheritable, therefore these items need to be reconsidered. Nonetheless, the results of the CINS for each Greek sub-group showed that the higher the involvement in evolution education, the higher the students' performances on the CINS test. This linear correlation, together with other evidence, supports the CINS authors' claims about the usefulness of the CINS as an assessment of instruction. Unfortunately, Greek university students gave many teleological and proximate answers to many of the CINS items. Comparisons between least and most evolutionary educated university students revealed that the latter gave more evolutionary answers. Oddly, advanced biology majors students did not show an improvement in all the 20 items of the CINS (only in 14 out of the 20 items) compared to novice biology students. They even gave more teleological answers to the concept natural resources are limited than novice biology majors students. Finally, Greek university students' level of knowledge of ENS seems to be closer to Canadian than US students'. 相似文献

The purpose of this research study was to (a) describe how concept mapping can be used as an integral instructional strategy for teaching a college course on evolution, (b) evaluate the utility of incorporating concept mapping in a college course on evolution, (c) determine whether students' concept maps reveal “critical junctures” in learning as the course unfolds, and (d) assess the impact of concept mapping on students' study practices and on students' understanding of course content. Key findings include: (a) Critical junctures in learning evolution can be identified by monitoring the degree of concordance of superordinate concepts appearing on the class set of concept maps submitted after each of the course lectures; (b) students who made concept maps reported spending an average of 37% more study time on this college biology course than on their previous biology courses; and (c) the use of “seed concepts,” “micromapping,” a standard concept map format, and a standard concept map checklist made the strategy feasible for the instructor to implement and for the student to adopt. A concept map performance index formulas was also developed for this research study in order to assess students' overall mapping performance. 相似文献

With the advancements in technology networks, mobile learning has been extensively applied in teaching contexts, enabling closer interaction between students and authentic environments. Previous studies have indicated that, when learning in real-world contexts, students need to interact with real learning targets and peers as well as the digital learning content; thus, effective learning strategies or tools are generally required for helping them organize knowledge and for promoting peer interactions. As a result, the present study developed a bi-directional peer-assessment-based concept mapping system, which not only engages students in assessing peers’ concept maps, but also encourages them to evaluate or respond to peers’ ratings and comments. To explore the effectiveness of this learning system, the study conducted an experiment in elementary science classes. A total of 101 fifth graders from four classes were recruited to participate in the study. Two classes were assigned to the experimental group and two to the control group. The experimental group adopted the bi-directional peer-assessment approach, while the control group adopted the conventional peer assessment approach for concept mapping. The results reveal that the bi-directional peer-assessment-based concept mapping system can not only increase students’ learning achievement and the completeness of their concept mapping, but can also enhance their critical thinking tendency and the feedback quality of their peer assessment. 相似文献

The results of recent studies into the use of the concept mapping heuristic seem to demonstrate that meaningful learning results through its use in science classrooms. While this underscores the need to use more effective instructional strategies in science teaching, the issue of the intervening variable of anxiety in learning and science achievement, and the possible use of a metacognitive strategy in anxiety reduction have not been addressed. This study, therefore, sought to find out if the metacognitive strategy of concept mapping reduces anxiety and thereby enhances achievement in biology. A total of 51 (30 boys, 21 girls) senior secondary one (grade 10) students participated in this experiment. Two instruments—the Zuckerman Affect Adjective Checklist and the Biology Achievement Test—were used in pre- and posttest administrations to measure the treatment effect on anxiety and achievement, respectively. Findings support the stand that concept mapping is significantly more effective than the traditional/expository teaching strategy in enhancing learning in biology. In addition, it apparently reduces students' anxiety towards the learning of biology. A significant reduction of anxiety was noticed for male subjects. 相似文献

Incorporating authentic research experiences in introductory biology laboratory classes would greatly expand the number of students exposed to the excitement of discovery and the rigor of the scientific process. However, the essential components of an authentic research experience and the barriers to their implementation in laboratory classes are poorly defined. To guide future reform efforts in this area, we conducted a national survey of biology faculty members to determine 1) their definitions of authentic research experiences in laboratory classes, 2) the extent of authentic research experiences currently experienced in their laboratory classes, and 3) the barriers that prevent incorporation of authentic research experiences into these classes. Strikingly, the definitions of authentic research experiences differ among faculty members and tend to emphasize either the scientific process or the discovery of previously unknown data. The low level of authentic research experiences in introductory biology labs suggests that more development and support is needed to increase undergraduate exposure to research experiences. Faculty members did not cite several barriers commonly assumed to impair pedagogical reform; however, their responses suggest that expanded support for development of research experiences in laboratory classes could address the most common barrier. 相似文献

This study was designed to learn if students perceived an interactive computer/videodisc learning system to represent a viable alternative to (or extension of) the conventional laboratory for learning biology skills and concepts normally taught under classroom laboratory conditions. Data were collected by questionnaire for introductory biology classes at a large midwestern university where students were randomly assigned to two interactive videodisc/computer lessons titled Respiration and Climate and Life or traditional laboratory investigation with the same titles and concepts. The interactive videodisc system consisted of a TRS-80 Model III microcomputer interfaced to a Pioneer laser-disc player and a color TV monitor. Students indicated an overall level satisfaction with this strategy very similar to that of conventional laboratory instruction. Students frequently remarked that videodisc instruction gave them more experimental and procedural options and more efficient use of instructional time than did the conventional laboratory mode. These two results are consistent with past CAI research. Students also had a strong perception that the images on the videodisc “were not real” and this factor was perceived as having both advantages and disadvantages. Students found the two approaches to be equivalent to conventional laboratory instruction in the areas of general interest, understanding of basic principles, help on examinations, and attitude toward science. The student-opinion data in this study do not suggest that interactive videodisc technology serve as a substitute to the “wet” laboratory experience, but that this medium may enrich the spectrum of educational experiences usually not possible in typical classroom settings. 相似文献

Meiosis is a biological concept that is both complex and important for students to learn. This study aims to explore first‐year biology students’ explanations of the process of meiosis, using an explicit theoretical framework provided by the Structure of the Observed Learning Outcome (SOLO) model. The research was based on responses of 334 first‐year biology students to practical and examination questions about meiosis, together with student interviews. Students’ written responses were coded, which resulted in a hierarchy of qualitatively different categories consistent with recent developments in the SOLO model. Most responses described a number of the less abstract elements of meiosis, but not in a coherent, relational manner, and interviews elucidated several areas of confusion about meiosis and its subordinate concepts. These findings are consistent with much previous research, and provide insights into both the use of the SOLO model as a research tool and students’ understandings of meiosis. In conjunction with previous research, the results of this study raise questions beyond its local context about the match between students’ apparent understandings and university expectations. The implications of the study relate to the use of terminology, the treatment of meiosis in textbooks, and some specific issues of pedagogy. 相似文献

ABSTRACT: Problem-based learning (PBL) can provide an enhanced appreciation of the relationship between culture and food for students who aspire to become dietitians or nutrition educators; however, large university classes often inhibit the use of PBL. A professor who specializes in research documenting the relationships among food and culture took 17 Canadian university students, many of whom were studying nutrition and food science, to southern Italy where they learned about Mediterranean diets and Italian food culture. PBL was implemented by encouraging students to work together to solve problems, and by the completion of assignments that promoted observation of and interaction with the local culture. Students evaluated the experience positively with majority agreement that the quality of course content was excellent, that knowledge of the subject areas increased, and that the courses challenged students to critically think about issues. Despite a focused effort on PBL in the courses, not all students agreed that the courses helped them to develop the ability to solve real problems in this field. This may have been due to unawareness of dietetic competencies by some students. Many of the assignments used in Italy could be adopted for use in food culture classes in North America, or by postsecondary instructors planning travel study programs in Italy. 相似文献

ABSTRACT: Researchers and educators call for educational programs that teach youth about food safety. In this study, researchers used qualitative research methods (interviews and concept mapping) to ascertain elementary students' understandings of food spoilage and preservation benchmarks based on national science education standards. Constructivist learning theory and its attendant qualitative methods framed the study. Few students understood the causes of spoilage and most were unable to discuss the role of bacteria or germs in meat. Students with an understanding of microorganisms clearly explained methods of preventing spoilage, while students who did not understand the microorganism concept could not. Constructivist research methods were fruitful in unearthing students' conceptions related to food spoilage. This research has implications for university food science faculty members interested in strengthening their teaching practice by focusing on helping students develop conceptual understanding. 相似文献

University students are too often challenged by their limited skills in application, investigation, relational thinking, and communication of ideas. In this study, we have combined 3 tools that potentially can support and foster students’ development in the above mentioned areas through student collaboration, concept mapping, and electronic technologies. The participants in this study were 26 students in two intact classes in learning theories. In groups of 3 to 5 students, they were asked to generate 3 concept maps and accompanying prose over the term on 3 major issues in the field of learning. Through the use of interviews, questionnaires, and student generated concept maps, students reportedly enjoyed concept mapping for its organizational and relational properties but preferred sharing their concept maps and dialoguing with one another in a synchronous mode where immediate feedback and flow of thinking could be maintained when involved in constructing maps. Moreover, they did not like the redundancy offered by both prose and concept map outputs, suggesting that while concept mapping can be an arena for generating and generally structuring ideas, prose can be a means of communicating such ideas in a form that is common to most people. This is particularly important for teachers and students who have difficulty navigating through maps alone. 相似文献

Direct teaching of problem-solving methods to high school physics students met with little success. Expert problem solving depended upon an organized knowledge base. Concept mapping was found to be a key to organizing an effective knowledge base. The investigation of the effect of the degree of concept mapping on achievement was the purpose of this study. Six intact high school physics classes, taught by this investigator, took part in the study. Two classes were control groups and received standard instruction. Four classes received six weeks of concept-mapping instruction prior to the unit under study. Two of these four classes were the low-level treatment group and were required to submit concept maps at the conclusion of the instruction. The other two classes were the high-level treatment group and were required to submit concept maps at the beginning and at the conclusion of the unit under study. One class from each treatment group took a pretest prior to instruction. An analysis of the posttest results revealed no pretest sensitization. A one-way analysis of covariance indicated a significant main effect for the treatment level at the p < 0.05 level. A pair of single-df comparisons of the adjusted treatment means resulted in significant differences (p < 0.05) between the control group and the average of the treatment means as well as between the two experimental groups. It can be concluded that for this sample (upper-middle-class high school physics students) mapping concepts prior to, during, and subsequent to instruction led to greater achievement as measured by posttest scores. 相似文献
