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

First-year algebra high school students of various ability levels were presented lessons concerning the application of geometry theorems. The lessons varied in terms of the complexity of the examples that were shown. After the lessons, students completed a questionnaire concerning their perceptions of the lessons, and then they were tested over the material covered in the lessons. With test scores as the dependent variable, the main effect due to lesson complexity was not significant. With student perception as the dependent variable, significant main effects due to lesson complexity were identified. Significant interactions between lesson complexity and student ability level were identified also. These results are discussed in terms of teaching secondary school mathematics.  相似文献

To increase the teacher efficacy of student teachers, they need positive classroom experiences: mastery experiences. These mastery experiences have to be created by the student teachers themselves. Therefore, student teachers need a tool to better understand problematic teaching experiences and help them create positive classroom experiences. Nine student biology teachers used this attribution support tool when reflecting on multiple lessons taught in classes they considered difficult. They scored their lessons and filled in a teacher efficacy questionnaire after each lesson. The results show that teacher efficacy increased and the number of failures during the lessons decreased; on average, the self-awarded marks per teacher per lesson increased, indicating an increase in mastery experiences. Therefore, the attribution tool seems to be a promising tool for student teachers to enhance their teacher efficacy and to support reflection on problematic teaching experiences.  相似文献

This study demonstrated that the modality principle applies to multimedia learning of regular science lessons in school settings. In the first field experiment, 27 Dutch secondary school students (age 16–17) received a self-paced, web-based multimedia lesson in biology. Students who received lessons containing illustrations and narration performed better on subsequent transfer tests than did students who received lessons containing illustrations and on-screen text. In the second field experiment, 55 Dutch secondary school students (age 16–17) received similar multimedia programs that allowed more self-pacing and required students to record the time to learn. The illustrations-and-narration group outperformed the illustrations-and-text group on subsequent transfer tests for students who required less time to learn but not for students who required more time to learn. The interaction of learning time spent with modality of presentation on post-test scores was studied. Implications for testing of the robustness of cognitive theory of multimedia learning are discussed.  相似文献

Given the globalization of science education and the different cultures between China and Germany, we tried to compare and explain the differences on teacher questions and real life instances in biology lessons between the two countries from a culture-related perspective. 22 biology teachers from China and 21 biology teachers from Germany participated in this study. Each teacher was videotaped for one lesson on the unit blood and circulatory system. Before the teaching unit, students’ prior knowledge was tested with a pretest. After the teaching unit, students’ content knowledge was tested with a posttest. The aim of the knowledge tests here was for the better selection of the four samples for qualitative comparison in the two countries. The quantitative analysis showed that more lower-order teacher questions and more real life instances that were introduced after learning relevant concepts were in Chinese lessons than in German lessons. There were no significant differences in the frequency of higher-order questions or real life instances that were introduced before learning concepts. Qualitative analysis showed that both German teachers guided students to analyze the reasoning process of Landsteiner experiment, but nor Chinese teachers did that. The findings reflected the subtle influence of culture on classroom teaching. Relatively, Chinese biology teachers focused more on learning content and the application of the content in real life; German biology teachers emphasized more on invoking students’ reasoning and divergent thinking.  相似文献

High school students of various ability levels were presented lessons concerning economics concepts. The lessons were varied according to their organization or structure. Students then were tested over their understanding of the concepts. The test questions ranged from simple recall of information (low level) to application of economics principles (high level). Students scored generally higher when they were presented highly structured lessons. Scores were higher on the low level questions than on the high level questions. Significant interactions occurred between student ability level and lesson structure, as well as between cognitive level of questions and lesson structure. These results are discussed in terms of previous research on lesson structure.  相似文献

The study was designed in an attempt to gain greater understanding of the kinds of learning processes engaged in by students during regular classroom instruction, and at investigating the students' level of understanding and problems in understanding parts or all of the lessons. Six school levels of male and female students from 44 secondary and pre-university classes (N=2719) were the subjects of this study. During the lessons, students and teachers were observed and video-taped. Following the lessons, students' reports of their learning processes were obtained using a questionnaire. The questionnaire also served as the basis for a follow-up interview of four randomly selected students from each of the sampled classes. The whole procedure was repeated for each class within a one-month period and for a different curricular area.

Analyses of student responses showed that more of the average ability students as compared to the high or low ability students reported understanding all of the lessons. However, the higher ability students were more likely to report using specific cognitive strategies to monitor their understanding of the lessons and in processing intellectual tasks and lesson content. They were able to provide more elaborate and more specific reasons for not understanding parts of the lessons. The results were interpreted in terms of physical and organizational characteristics of educational classrooms in Singapore. Instructional implications are discussed in relationship to both the findings and previous literature.  相似文献

The effects of studying alone or in cooperative learning groups on high- and average-ability students were investigated. Also examined were the effects of completing computer-based instruction using either a learner- or program-control version of a lesson. A total of 175 fourth-grade students were classified as being of high or average ability and randomly assigned to paired or individual treatments stratified by ability. Students completed training to enhance small-group interaction before completing a computer-based tutorial and a posttest. Following cooperative learning, students demonstrated increased achievement and efficiency as well as better attitudes toward both the computer lesson and grouping. Students completed more practice items and examples in program-control treatments than in learner-control treatments. However, the form of lesson control did not affect students' achievement or attitudes.  相似文献

Four groups of student teachers taught short lessons to small classes of children. According to the micro‐teaching format developed at Stanford University they then retaught a similar lesson approximately one hour later to a comparable but different group of children. In the intervening one‐hour period they received various kinds of feedback about the first lesson they had given. Analysis of the second lessons showed that the students who had both seen videotapes of their first lesson and been given information about their interaction with the class were likely to lecture less, elicit more spontaneous talk by the children and be rated higher by them.  相似文献

Following a model on the cyclical nature of teacher (“trait”) self-efficacy and context-, task- and situation-specific (“state”) mastery experiences (TSSME), we investigated the variability and effects of lesson characteristics (e.g. lesson sequence), student group characteristics (e.g. proportion of students receiving free school meals) and teacher characteristics (e.g. teacher experience) on teachers' situation-specific mastery experience. Forty-three teachers reported on 1,055 lessons in 385 student groups using electronic questionnaires in Personal Digital Assistants during a period of 2 weeks. Two domains of TSSME (support of learning and organisation of classrooms) and perception of students (engagement and behaviour) were found. Multilevel models found roughly a quarter of the variance in TSSME between teachers, a quarter between student groups and half between lessons. Student group characteristics differentially predicted TSSME. Perceived student engagement was more predictive of TSSME than perceived student behaviour. More experienced and high-efficacy teachers had higher TSSME. The findings have implications for our understanding of teachers' everyday practice with different student groups.  相似文献

A video-based program on lesson analysis for pre-service mathematics teachers was implemented for two consecutive years as part of a teacher education program at the University of Lazio, Italy. Two questions were addressed: What can preservice teachers learn from the analysis of videotaped lessons? How can preservice teachers’ analysis ability, and its improvement, be measured? Two groups of preservice teachers (approximately 140 in total) participated in the program. A three-step lesson analysis framework was applied to three lesson videos: (1) goal(s) and parts of the lesson; (2) student learning; and, (3) teaching alternatives. Preservice teachers’ ability to analyze lessons was measured through an open-ended pre- and post-assessment. In the assessment, preservice teachers were asked to mark and comment on events (in a lesson not included in the program) that they found interesting for: teachers’ actions/decisions; students’ behavior/learning; and, mathematical content. A coding system was developed based on five criteria: elaboration, mathematics content, student learning, critical approach, and alternative strategies. In both studies, the ability to analyze instruction improved significantly on all five criteria. These data suggest promising directions for the development of both an instrument to measure lesson analysis abilities and a model for teacher learning.  相似文献

Teaching for understanding requires teachers to organize thought-demanding activities which continually challenge students to apply and extend their prior knowledge. Research shows that student teachers often are unable to develop lessons in teaching for understanding. We explored how a domain-specific heuristic can assist student biology teachers in developing problem-posing lessons according to teaching for understanding. Worksheets of lesson plans were analyzed according to criteria for problem-posing lessons. Furthermore, student teachers’ perceptions of the design heuristic’s usefulness were categorized in a cyclical process. In general, the heuristic appeared helpful to most student teachers for designing problem-posing lessons satisfactory according to the criteria. Furthermore, teachers indicated that using the heuristic deepened their subject matter knowledge and their awareness of pupils’ prior knowledge.  相似文献

When designing lessons to meet the needs of our increasingly diverse population of students, educators need to rethink planning and structuring lessons so that all students achieve better results. Therefore, teacher preparation programmes need to prepare pre‐service teachers accordingly. Within this paper, a new lesson planning template is unveiled that builds on many of the foundational concepts of inclusive education. This template is meant for teacher educators to use with pre‐service teachers across the curriculum to guide the design of inclusive lessons. This paper discusses the foundations, unique features, and applications of this student‐centred lesson design template to create creative and active learning for students in inclusive classrooms.  相似文献

This article reports on active teaching and learning approaches taken by one English teacher and a secondary PGCE student‐teacher to bring about changes to the work culture in a Year 8 mixed‐ability class. It is written by the PGCE tutor, student‐teacher, class teacher and external examiner, following an observation of one lesson, in a series of lessons, given by the student‐teacher. This lesson is analysed through its motivating content, approach to critical reading, inherent creativity and active approaches to learning. It indicates how a challenging class has been changed by approaches that provide alternatives to currently advocated objectives‐driven and direct instructional approaches.  相似文献

This case study of a first-year and an experienced teacher presents an analysis of the place and frequency of three types of questions: probing, guiding, and factual. We examined the use of these questions in the course of five lessons, in order to study the relationship between the part of the lesson and types of questions asked. In addition, we interviewed the teachers to gain insights into their reasons for asking different types of questions. Both teachers asked many more factual questions than other types of questions regardless of their teaching strategies. Both asked more probing questions during the summary part of the lessons than in other parts. The first year teacher asked more probing questions overall than the experienced teacher, except in a lesson in which the experienced teacher engaged student with manipulatives. Guiding questions were rarely used by either teacher. In the interviews, both teachers said asking higher order questions was important for better students’ learning, even though they asked relatively few probing or guiding questions. Using the indicators we developed for question types, we found that the two teachers were aware of the functions of questions they used. Even after a considerable amount of time had elapsed, they were able to recall the lesson from a video clip and explain why they used questions with particular students or in a specific situation  相似文献

This study explored a modified version of Japanese Lesson Study to determine whether and how it influenced preservice elementary teachers in their abilities to deliver science lessons that included nature of science (NOS) to their own students. We used a case study approach that focused on one subset of a cohort of preservice elementary teachers within their field placement settings. Data sources included lesson plans, lesson feedback forms, videotapes of delivered lessons, and videotapes of lesson study feedback sessions. Early in the semester peers provided feedback on content, and later in the semester peers provided feedback on classroom management as well as content during the lesson study feedback sessions. We found that preservice elementary teachers were able to provide feedback to their peers regarding how to include NOS in their science lessons, yet did not naturally included NOS connections within their own lessons.  相似文献

The purpose of this study was to determine whether third-grade teachers' instructional actions during reading comprehension lessons contributed to their students' reading comprehension achievement. Our framework focused on teachers' emphasis on three dimensions of instruction (pedagogical structure, teacher-directed instruction, and support for student learning), as observed in comprehension lessons across a year. Third-grade teachers' instruction was analyzed first by measuring their latent propensity to engage in instructional actions in the three dimensions and then by using these latent variables in a multilevel model to examine their students' gains in reading comprehension. Results provided support for the theoretical dimensions, taking into account contextual variables including lesson, student, and teacher characteristics; teachers' engagement in teacher-directed instruction and their support for student learning significantly contributed to their students' reading comprehension. Results suggest that analysis of teachers' instructional actions within and across lessons is a promising approach for the study of effective reading instruction.  相似文献

An essential question when computing test–retest and alternate forms reliability coefficients is how many days there should be between tests. This article uses data from reading and math computerized adaptive tests to explore how the number of days between tests impacts alternate forms reliability coefficients. Results suggest that the highest alternate forms reliability coefficients were obtained when the second test was administered at least 2 to 3 weeks after the first test. Even though reliability coefficients after this amount of time were often similar, results suggested a potential tradeoff in waiting longer to retest as student ability tended to grow with time. These findings indicate that if keeping student ability similar is a concern that the best time to retest is shortly after 3 weeks have passed since the first test. Additional analyses suggested that alternate forms reliability coefficients were lower when tests were shorter and that narrowing the first test ability distribution of examinees also impacted estimates. Results did not appear to be largely impacted by differences in first test average ability, student demographics, or whether the student took the test under standard or extended time. It is suggested that for math and reading tests, like the ones analyzed in this article, the optimal retest interval would be shortly after 3 weeks have passed since the first test.  相似文献

Advances in online geospatial technologies (GST) have expanded access to K-12 classrooms which has implications for the support teachers require to effectively integrate GSTs to promote learning. Previous studies have shown the impact of GST-integrated lessons on student engagement, spatial thinking skills, and/or content knowledge; however, most of these studies have been small in scope and scale and frequently focus on the affordances of the technology, without addressing the context of the implementation and student characteristics for whom GST is most impactful. We attempt to address some of these gaps. Our program scaled an effective GST-focused professional learning and development program to a national audience through a facilitator development model. This paper explores the student characteristics and lesson factors that resulted in student interest in science and technology and careers in those fields. After teaching a Geospatial Inquiry lesson created during a teacher workshop, teachers (n = 82) submitted the lessons and surveys on the implementation of Geospatial Inquiry lessons. The implementation surveys and lessons were scored for alignment to the principles of high-quality Geospatial Inquiry. Students (n = 1924) completed a post-lesson retrospective survey and indicated the extent to which their perceptions and attitudes toward science and technology changed because of the lesson. Results indicate that teacher GST performance is associated with increases in student outcomes. Students with previous exposure to science activities were more likely to have increased interest and excitement in science and careers in science but decreased interest in technology careers. Students who had previous exposure to technology activities had increased interest and excitement in technology and careers in technology but decreased interest in science careers. Geospatial Inquiry lessons also had a significant impact on students who are traditionally underrepresented in STEM fields. After participating in the lessons, students who identify as female reported higher engagement and interest in science and higher interest in science careers. Students who identified as Black or Hispanic also reported higher interest and excitement in science and technology, and students who identified as Black reported marginally higher interest in science careers.  相似文献
