思考语文教学策略，必须正视这样几个问题：一是策略的目标是放在如何获取知识还是如何运用知识；教学中着力解决某个问题还是致力于解决某类问题；把生活引进语文学习还是把语文学习当成生活。语文教育是树人的教育，教学策略应充分发挥其树人效应。为此，要认识学生成长的规律，要研究语文教育到底能为学生的成长做些什么?成长教育中的语文教学策略可以归结为四个字：品、评、悟、化。 相似文献

现代课堂教学设计，它是研究课堂教学这个复杂系统的一项智力工程，是实现教学目的有力保证，是连接先进教学理论和教学实践的桥梁，是使教学实现科学性与艺术性统一的有效途径，是课堂教学现代化的重要标志之一。我们认为，现代课堂教学的基本任务应是促进学生有意义学习。而课堂教学促进学生有意义学习的基本点，归纳起来有如下四点： 一、认知停靠点 有意义学习不是凭空产生的，正如奥苏贝尔所说，有意义学习的第一个条件就是学习者头脑中应具有可以用来同化新知识的适当观念。如果我们把学习者头脑比做一片港湾，新知识比做一艘轮船，那… 相似文献

The purpose of this study was to explore relationships among school students' (N = 189) meaningful learning orientation, reasoning ability and acquisition of meaningful understandings of genetics topics, and ability to solve genetics problems. This research first obtained measures of students' meaningful learning orientation (meaningful and rote) and reasoning ability (preformal and formal). Students were tested before and after laboratory-based learning cycle genetics instruction using a multiple choice assessment format and an open-ended assessment format (mental model). The assessment instruments were designed to measure students' interrelated understandings of genetics and their ability to solve and interpret problems using Punnett square diagrams. Regression analyses were conducted to examine the predictive influence of meaningful learning orientation, reasoning ability, and the interaction of these variables on students' performance on the different tests. Meaningful learning orientation best predicted students' understanding of genetics interrelationships, whereas reasoning ability best predicted their achievement in solving genetics problems. The interaction of meaningful learning orientation and reasoning ability did not significantly predict students' genetics understanding or problem solving. Meaningful learning orientation best predicted students' performance on all except one of the open-ended test questions. Examination of students' mental model explanations of meiosis, Punnett square diagrams, and relationships between meiosis and the use of Punnett square diagrams revealed unique patterns in students' understandings of these topics. This research provides information for educators on students' acquisition of meaningful understandings of genetics. © 1996 John Wiley & Sons, Inc. 相似文献

This paper presents the results of part of an investigation carried out with fourth‐level Spanish secondary education students (15 years old), in which we implemented a teaching unit based on problem‐solving methodology as an investigation to teach genetics and human inheritance curricular contents. By solving open problems, the students experienced a conceptual restructuring that stayed with them over time and involved the following specific theories: the location of hereditary information, the transmission of hereditary information, and the appearance of new characteristic. The learning connections between these specific theories were also studied. Furthermore, these results were compared with a control group that worked with closed problems, the usual approach to genetics teaching in Spanish classrooms. Consequently, we were able to verify that our methodology results in better learning. 相似文献

Genetics Reasoning with Multiple External Representations 总被引：1，自引：0，他引：1
This paper explores a case study of a class of Year 10 students (n=24) whose learning of genetics involved activities of BioLogica, a computer program that features multiple external representations (MERs). MERs can be verbal/textual, visual-graphical, or in other formats. Researchers claim that the functions of MERs in supporting student learning are to complement information or processes, to constrain the interpretation of abstract concepts, and to construct new viable conceptions. Over decades, research has shown that genetics remains linguistically and conceptually difficult for high school students. This case study using data from multiple sources enabled students' development of genetics reasoning to be interpreted from an epistemological perspective. Pretest-posttest comparison after six weeks showed that most of the students (n=20) had improved their genetics reasoning but only for easier reasoning types. Findings indicated that the MERs in BioLogica contributed to students' development of genetics reasoning by engendering their motivation and interest but only when students were mindful in their learning. Based on triangulation of data from multiple sources, MERs in BioLogica appeared to support learning largely by constraining students' interpretation of phenomena of genetics. 相似文献

Summary Some important results that relate to classroom learning and teaching of problem solving emerge from these case studies. These
are now summarized as follows.
In terms of the students' potential learning experiences of problem solving, it was found that the students were mainly witnessing
their teachers' demonstrations of using rules or algorithms for solution to problems. Repeated practice of solving the sorts
of problems that occur in examinations was also emphatically included as part of the learning experience. The students were
not exposed to a range of strategies that could possibly be used to solve the same problems. There was no explicit teaching
of important problem solving skills such as translation skills (comprehending, analyzing, interpreting, and defining a given
problem) and linkage skills (concept relatedness between two concepts or using cues from the problem statements to associate
ideas, concepts, diagrams, etc. from memory). When teachers solve problems they use, in general, several strategies to solve
the same class of problems and they are very careful and explicit about translating problem statements, making relevant linkages
and checking.
These absences in the teachers' teaching of problem solving (and hence in the students' range of learning experiences) are
particularly interesting because they are part of the teachers' own repertoire of skills. Accordingly, it may not be too difficult
to get teachers to include them in their teaching. This would mean that the students' range of learning experiences for problem
solving would be very much strengthened. 相似文献

This study is an attempt to analyze students' construction of function based problem solving methods in introductory algebra.
It claims that for functions to be a main concept for learning school algebra, a complex process that has to be developed
during a long period of learning must take place. The article describes a longitudinal observation of a pair of students that
studied algebra for 3 years using a function approach, including intensive use of graphing technology. Such a long observation
is difficult to carry out and even more difficult to report. We watched for three years classrooms using the ‘Visual-Math’
sequence, and sampled students that exhibited various levels of mathematics achievement. The analysis method presented here
is a non-standard case study of a pair of lower achievers students and their work is often juxtaposed to the work of other
pairs participating in the study. The students' attempts to solve a linear break-even problem is analyzed along three interviews
which present the development of the use of mathematical resources and the patterns of problem solving at different learning
phases. Beyond describing solving attempts, the article offers terms for describing and explaining what and how do learners
appreciate and make out of solving introductory school algebra problems over a three years course.

This study explored the use of wikis in a science inquiry-based project conducted with Primary 6 students (aged 11–12). It used an online wiki-based platform called PBworks and addressed the following research questions: (1) What are students’ attitudes toward learning with wikis? (2) What are students’ interactions in online group collaboration with wikis? (3) What have students learned with wikis in a science inquiry-based project in a primary school context? Analyses of the quantitative and qualitative data showed that with respect to the first research question, the students held positive attitudes toward the platform at the end of the study. With respect to the second research question, the students actively engaged in various forms of learning-related interactions using the platform that extended to more meaningful offline interactions. With respect to the third research question, the students developed Internet search skills, collaborative problem solving competencies, and critical inquiry abilities. It is concluded that a well-planned wiki-based learning experience, framed within an inquiry project-based approach facilitated by students’ online collaborative knowledge construction, is conducive to the learning and teaching of science inquiry-based projects in primary school. 相似文献

Researchers have pointed out the difficulties that high school students have in understanding meiosis and the infrequency with which they acknowledge the conceptual relationships between meiosis and classical genetics, particularly when solving genetics problems. The research described in this article paints a different picture of students' reasoning with meiosis as they solved complex, computergenerated genetics problems, some of which required them to revise their understanding of meiosis in response to anomalous data. Details are presented of the ways students used their knowledge of meiosis to recognize anomalous data, to generate hypotheses as part of the revision of explanatory models, and to assess these hypotheses. The findings from this research, contrary to most reports in the literature, suggest that students are able to develop rich understanding of meiosis and can utilize that knowledge to solve genetics problems. 相似文献
