College students (N = 41) were randomly assigned to one of two groups defined by the teacher's clarity in the lesson, i.e., high-clarity versus low-clarity presentation on genetics. After the lesson the subjects completed a test on the contents of the lesson and then rated the lesson presentation. Students in the high-clarity group achieved more (although not significantly) than students in the low-clarity group. Students perceived the high-clarity lesson as significantly clearer than the low-clarity lesson. These findings are discussed in relation to previous research on teacher clarity.  相似文献

The East Asian learner paradox refers to the apparent contradiction between the teacher-dominated learning environment in East Asia, which is generally perceived to be non-conducive to learning, and the outstanding performance of East Asian students in comparative studies. This study attempts to explain this phenomenon based on the perspectives of a Chinese teacher from Shanghai, his group of students, and the author's own observations as a researcher. The analysis was based on the theory of variation and it showed how the teacher handled the relationship between the procedural and conceptual aspects of the mathematics. This analysis also shows that the teacher in this study had a strong pedagogical belief and highly valued his students' thinking and participation. At the same time, his students also expressed a consistent concern for learning the mathematical content. Therefore, this author argues that what seems to be a teacher-dominated lesson may actually be interpreted as an alternative form of student-centredness, which is accepted in the teacher's culture.  相似文献

Language in Use     
The conference set up one commission to look at the particular place of the English lesson within a framework of Language across the Curriculum. Such a view of language in school could have awkward implications for English: that either a pupil's growth in language might be provided for by the work of the whole curriculum, or that the English lesson should ‘service’ a pupil's language for his work in other studies. Two questions arise: are there certain responses and experiences which pupils need time for and which can only be allowed for in the English lesson ? And are there particular studies in language that only the English lesson can take responsibility for ? In order to set this discussion on its way, Peter Doughty was invited to talk about the special work which his team at University College, London, had been doing on language in English, and which has now been incorporated into material known as Language in Use. We print here an extract from his paper, published by the Schools Council, a fuller version of which is available on application from Great Portland Street, London, W.1. Fred Inglis took issue with this point of view about language in English.  相似文献

The Self Lesson Report Form (SLRF) was designed as an alternative either to direct classroom observation or to commonly used questionnaires in which students and/or teachers report on general practices used in their classes. In the SLRF teachers report what happened in their last lesson. Certain items are structured while others are open. A special procedure was developed for the analysis of the open answers. A high level of reliability was obtained by comparing results of teachers' and observers' reports on the same lesson. Two hundred and fifty SLRF's were analyzed and the results are reported to illustrate the kind of information which can be obtained with this instrument. It was found that, on the average, junior high science classes in Israel are inquiry oriented, have abundance of discussions and hands-on laboratory activities which are closely supervised by the teachers.  相似文献

To learn from a text, students must make meaningful connections among related ideas in that text. This study examined the effectiveness of two methods of improving connections—elaborative interrogation and diagrams—in written lessons about posterior probability. Undergraduate students (N = 198) read a lesson in one of three questioning conditions (read twice, embedded questioning, and elaborative interrogation) and one of three diagram conditions (text only, diagram without redundant text, and diagram with redundant text). Elaborative interrogation negatively affected learning from the lesson, relative to reading the lesson twice. One possible explanation for this finding is that the quality of answers to the elaborative interrogations was poor. When the lesson was read twice, diagrams helped learning from the lesson relative to text only. Implications of these findings for instruction in probabilistic reasoning are discussed.  相似文献

COMMUNITY BUILDING: A NEW ROLE FOR THE JEWISH DAY SCHOOL   总被引：1，自引：0，他引：1  
Wearing a swastika armband, I entered the classroom carrying a copy of Hitler's Mein Kampf. Placing it on the music stand I employed as a makeshift lectern, I peered around the room until the students became silent. Then I began to read sections of Hitler's venomous tome, the hateful words cutting through me like a knife. As I read, I noticed that a few students stiffened. I had students analyze Hitler's quotes, addressing them as either “Herr” or “Fraulein.” After this lesson, I explained why I used such tactics. I told them death and destruction during World War II was only part of studying the Holocaust. Learning where the Jew-hatred came from and its context within Nazism was also important. And that meant comprehending Mein Kampf. Closing the book, I removed the twisted cross and slowly tore it into small pieces.  相似文献

Two focusing hypotheses were evaluated. First, do adjunct questions, focusing on science concepts and inserted after computer-animated sequences, selectively alter students' attentional or practice processing and thus produce differential learning effects? Theoretically, such questions selectively focus students' attention and enhance concept learning of focused concepts. Second, do these questions still provide enough metacognitive scaffolding to produce differential learning effects when only the first 8 out of 12 sequences are followed by focusing questions? Eighth-grade students (n = 160) were randomly assigned to a control group (lesson alone) or one of four treatment groups (lesson plus 12 questions focusing either on heat or on temperature, or lesson plus the same first 8 questions on heat or temperature followed by 4 placebo questions). Two significant two-way interactions with widely varying F ratios supported the differential focusing hypotheses (12 questions—more robust interaction, 8—less robust interaction).  相似文献

The purpose of this study is to provide insight into short-term professionalization of teachers regarding teaching socioscientific issues (SSI). The study aimed to capture the development of science teachers' pedagogical content knowledge (PCK) for SSI teaching by enacting specially designed SSI curriculum materials. The study also explores indicators of stronger and weaker development of PCK for SSI teaching. Thirty teachers from four countries (Cyprus, Israel, Norway, and Spain) used one module (30–60 min lesson) of SSI materials. The data were collected through: (a) lesson preparation form (PCK-before), (b) lesson reflection form (PCK-after), (c) lesson observation table (PCK-in-action). The data analysis was based on the PCK model of Magnusson, Krajcik, and Borko (1999). Strong development of PCK for SSI teaching includes “Strong interconnections between the PCK components,” “Understanding of students' difficulties in SSI learning,” “Suggesting appropriate instructional strategies,” and “Focusing equally on science content and SSI skills.” Our findings point to the importance of these aspects of PCK development for SSI teaching. We argue that when professional development programs and curriculum materials focus on developing these aspects, they will contribute to strong PCK development for SSI teaching. The findings regarding the development in the components of PCK for SSI provide compelling evidence that science teachers can develop aspects of their PCK for SSI with the use of a single module. Most of the teachers developed their knowledge about students' understanding of science and instructional strategies. The recognition of student difficulties made the teacher consider specific teaching strategies which are in line with the learning objectives. There is an evident link between the development of PCK in instructional strategies and students' understanding of science for SSI teaching.  相似文献

This paper discusses the ways in which teacher educators can effectively engage prospective teachers (PTs) in lesson study during mathematics methods courses. Evidence from this work suggests that engagement in lesson study provides PTs with opportunities to strengthen their knowledge about mathematics, students, and pedagogy. More specifically, the results demonstrated that lesson study helped PTs to engage in deep and thoughtful discussions about mathematics, reflect on their teaching, and make effective changes to their lessons that showed noticeable improvements in student learning. Recommendations from this work provide specific methods-course suggestions on the implementation of lesson study as a model for PTs' professional and practitioner development, including strategies and guiding questions that teacher educators can utilize to help deepen PTs' knowledge about mathematics, teaching, and student learning.  相似文献

In this article, we address the choice of suitable instructional units that might serve as the basis for cross-cultural analyses of classroom practice. Our argument draws on analyses undertaken as part of the Learner's Perspective Study (LPS). The database comprised a three-camera video record of sequences of 10 consecutive lessons in each classroom, supplemented by post-lesson video-stimulated interviews with teachers and students: a total of over 180 videotaped lessons, over 50 teacher interviews and almost 400 student interviews. The results of these analyses challenge the suitability of the lesson as the unit of comparative analysis. In particular, the location of the lesson in the topic sequence is seen to be a key influence on the lesson's structure, critically affecting the teacher's deployment of the constituent activities that we have called ‘lesson events.’ The lesson event is proposed as an alternative unit of international comparative analysis of classroom practice.  相似文献

It would be difficult to find any pedagogical story that is comparable to that of jugyou kenkyuu (or lesson study in English) that has been practised for over a century in Japan in isolation and became a method that was used worldwide in less than 10 years. Because of its uniqueness and its history, it is an irrefutable challenge to understand what it is really about, how its basic aspects such as a lesson or teachers' knowledge and its development, the culture of education, the measurability of educational activities and other main aspects of education are or can be conceptualised and in which ways these can travel in a globalised arena of education. In this article, we try to give answers to these and some other relevant issues related to lesson study via the author's subjective view and individually‐constructed narrative.  相似文献

The purpose of this study was to investigate the effects of the Common Knowledge Construction Model (CKCM) lesson sequence, an intervention based both in conceptual change theory and in Phenomenography, a subset of conceptual change theory. A mixed approach was used to investigate whether this model had a significant effect on 7th grade students' science achievement and conceptual change. The Excretion Unit Achievement Test (EUAT) indicated that students (N = 33) in the experimental group achieved significantly higher scores (p < 0.001) than students in the control group (N = 35) taught by traditional teaching methods. Qualitative analysis of students' pre‐ and post‐teaching conceptions of excretion revealed (1) the addition and deletion of ideas from pre‐ to post‐teaching; (2) the change in the number of students within categories of ideas; (3) the replacement of everyday language with scientific labels; and (4) the difference in the complexity of students' responses from pre‐ to post‐teaching. These findings contribute to the literature on teaching that incorporates students' conceptions and conceptual change. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 47: 25–46, 2010  相似文献

ABSTRACT

A Bayesian IRT-model approach was used to investigate the validity and reliability of student perceptions of teaching quality. Furthermore, the student perceptions were compared with ratings of teaching quality by external observers. Grade 4 students (n = 675) filled out a questionnaire that was used to measure their opinions about the lessons of their teachers. Three lessons of 39 teachers were recorded and rated by 4 raters. The analyses showed that student perception and lesson observation scales fit best in an 11-dimensional model, which was an indication of construct validity and discriminant validity. Student perception scales were reliable, although not all items contributed to the scales to the same extent. Student ratings and lesson observations scores generally correlated moderately (ranging from r = .18 to r = .50). Higher correlations were found for scales with a similar content; however, no clear pattern was apparent. Suggestions for future research are presented.  相似文献

Engaging students in a challenging (cognitively demanding) task and launching a mathematics lesson with a task before instruction are two characteristics of a reform-oriented approach to mathematics instruction often considered together. The authors systematically contrasted teaching with challenging tasks using a task-first lesson structure with that of a discussion-first lesson structure to three composite classes of first- and second-grade students (n = 73). Subsequent assessments of mathematical performance revealed that the discussion-first lesson structure was somewhat more efficacious in improving fluency performance but both structures similarly improved problem-solving performance. The findings suggest there is more than one way of incorporating challenging tasks into mathematics lessons to produce sizeable learning gains.  相似文献

This paper presents the development and evaluation of a web‐based lesson—Lesson Rainbow. This lesson features multiple representations (MRs), which purposefully deliver concepts in relation to distinctive disciplinary subject areas through story‐based animations that are closely related to learners’ life experiences. The researchers selected 58 2nd‐year junior high school students as the participants (32 males and 26 females). A quasi‐experimental method together with semi‐structured interviews was utilised. This research project was intended to investigate students’ conceptual progress, and to evaluate the use of MRs and of situated learning components in the design of Lesson Rainbow. The statistical results indicated that: (1) students’ science concepts significantly increased (t= 3.84, p < 0.01) through the use of Lesson Rainbow, and (2) students thought that the use of MRs in this web‐based lesson was an effective pedagogical tool inasmuch as it allows for the learning of specific theoretical viewpoints in addition to the necessary background information. Lesson Rainbow employing MRs helps learners to understand the meanings of, and interrelationships between, different kinds of external representations. This kind of design facilitates their understanding of the correspondence between abstract symbolic expressions and real‐world situations.  相似文献

Assessing a student's acquisition rates (ARs) is a reliable way to determine how many new words should be taught in one lesson without reducing retention. Exceeding a student's AR can result in frustration and problem behaviors. The purpose of this study was to examine the effect of AR on the off‐task behavior of kindergarten students while participating in a commonly used sight‐word instruction video. Participants included 39 kindergarten students whose ARs were assessed before showing the sight‐word video. Behavior was measured as on‐ and off‐task using momentary time‐sampling with 10‐s intervals. Results indicated that students' time off task increased after exceeding their ARs, with a noticeable immediate increase. The implications and limitations of these results are discussed.  相似文献

In the 19th century, a shift in classroom technology from monitoring to recitation was staged in several European countries. The analysis draws on late 19th- and early 20th century lesson plans that were produced as part of the final teacher examination by students at two Swedish teacher training colleges, in order to explore how the lesson was restructured as a pedagogic text in the course of this transformation. The argument focuses upon the structure and transformation of the lesson designs, the discursive pattern of the text, the narrative involved, and the message or moral reflected in the text. The inquiry demonstrates that a classroom technology originally advocated in order to enhance the teacher's control of pupils and to influence children's minds, thoughts and morality became one instrument in the creation of a school for symbolic representation and meaning-making in a rapidly changing world of modernity.  相似文献

Incorporating engineering instruction into the elementary curriculum is not without challenges. Traditionally, researchers investigated using engineering design to promote students learning science concepts. More recently, researchers have conducted qualitative investigations to measure students' learning of engineering concepts after engaging in engineering design. In this study, we extended work on elementary engineering instruction by implementing an integrated engineering and writing unit with 58 third-grade students. Using stratified random assignment based on pre-intervention engineering vocabulary assessment scores, we assigned students to treatment (n = 28) or comparison (n = 30). During a 10-day unit, all students participated in design challenges, emulated the practices of actual engineers, and used writing to support and document their learning, as they designed and authored their own five-page pop-up books. Students in the treatment condition participated in additional writing during 8 of the 10 unit lessons. During this time, they responded to journal prompts related to lesson objectives. At the same time, students in the comparison condition participated in small-group discussions during which they discussed journal prompts orally. We found that all students made statistically significant gains from pre- to posttest on an engineering vocabulary assessment; total words written, number of different engineering concepts used, and depth of understanding of engineering concepts in a written essay response; and number of different engineering concepts used in an oral interview response, regardless of their incoming writing skills and regardless of whether they participated in additional writing or small-group discussion of lesson objectives. This study is the first to quantitatively document the effectiveness of a combined elementary engineering and writing intervention for promoting students' learning of engineering concepts in multiple ways (rote recall, written representation, and oral representation). We argue that literacy, particularly writing, provides an effective and feasible method for incorporating engineering instruction into the elementary curriculum.  相似文献

High school biology students (n = 48) were each randomly assigned to one of four groups defined by possible combinations of two teacher vagueness conditions (high vagueness versus low vagueness) and two post-lesson conditions (test, then lesson evaluation versus lesson evaluation, then test). Each group was presented a lesson over the vascular system of angiosperms. After the lesson, each group was tested on comprehension of the material and each group completed a lesson evaluation. Teacher vagueness terms significantly affected student achievement and student perception of lesson effectiveness. These findings are discussed in relation to previous research on teaching clearly.  相似文献

This study describes a lesson in which students engaged in inquiry in evolutionary biology in order to develop a better understanding of the concepts and reasoning skills necessary to support knowledge claims about changes in the genetic structure of populations, also known as microevolution. This paper describes how a software simulation called EVOLVE can be used to foster discussions about the conceptual knowledge used by advanced secondary or introductory college students when investigating the effects of natural selection on hypothetical populations over time. An experienced professor's use and rationale of a problem-based lesson using the simulation is examined. Examples of student misconceptions and naïve (incomplete) conceptions are described and an analysis of the procedural knowledge for experimenting with the computer model is provided. The results of this case study provide a model of how EVOLVE can be used to engage students in a complex problem-solving experience that encourages student meta-cognitive reflection about their understanding of evolution at the population level. Implications for teaching are provided and ways to improve student learning and problem solving in population genetics are suggested.  相似文献
