This study investigates three teachers’ uses of a dynamic geometry program (The Geometer’s Sketchpad) in their high school geometry classes over a 2-year period. The researchers examine teachers’ actions and questions during pivotal teaching moments to characterize mathematics instruction that utilizes technology. Findings support an association between teacher–tool relationships, predominant teacher actions, and questioning. 相似文献

Teaching geometry at the elementary level is challenging. This study examines the impact of van Hiele theory-based instructional activities embedded into an elementary mathematics methods course on preservice teachers’ geometry knowledge for teaching. Pre- and post-assessment data from 111 elementary preservice teachers revealed that van Hiele theory-based instruction can be effective in improving three strands of participants’ geometry knowledge for teaching: geometry content knowledge, knowledge of students’ van Hiele levels, and knowledge of geometry instructional activities. As a result, this paper offers implications for teacher educators and policy makers to better prepare elementary preservice teachers with geometry knowledge for teaching. 相似文献

Formative assessment is considered to be a promising teaching practice for promoting teaching and learning processes. The implementation of teaching practices into instruction involves intervening with a learning environment that is characterised by certain features of instructional quality. Our study aims to contribute to the understanding of formative assessment by analysing the interplay between a formative assessment intervention and aspects of general instructional quality. In a quasi-experimental study design, 15 teachers participated in a control group (n = 361 students) and 20 teachers in the intervention classes (n = 498 students) implemented a curriculum-embedded formative assessment tool in their ninth-grade mathematics classes. No effects were found for the intervention on the assessed aspects of general instructional quality (process-oriented instruction, teacher–student relationship, effective use of instructional time). However, multilevel regression analyses revealed an interaction effect between the intervention and process-orientation and the effective use of instruction time. Our findings suggest that implementing formative assessment tools do not seem to suffice regarding changes in general instructional quality, but that an intervention with detailed material and guidelines can counterbalance effects of instructional quality, fostering students’ achievement in classes with lower degrees of process orientation and a less effective use of instructional time. 相似文献

Educative curricula, curriculum materials that intentionally foster teacher professional development, can serve as a site for teacher learning through their use in daily instructional practices. The present article introduces a framework, Teacher Learning Opportunities in Mathematics Curriculum Materials (TLO-Math), for designing and evaluating mathematics curriculum materials’ educative features according to seven theoretically based variables: (1) mathematics content knowledge for teaching, (2) teacher knowledge of student thinking in mathematics, (3) teacher knowledge of disciplinary discourse in mathematics, (4) teacher knowledge of assessment in mathematics, (5) teacher knowledge of differentiated instruction in mathematics, (6) teacher knowledge of technology use in mathematics, and (7) teacher knowledge of mathematical community. Each variable is illustrated with a definition, guiding questions, discipline-specific literature, and examples from two sets of elementary mathematics curriculum materials. The development of the TLO-Math framework is a critical first step for further study of the use of mathematics curriculum materials as sites for teacher learning. 相似文献

This study was designed to increase reading comprehension and academic achievement of students through the use of a modified reciprocal teaching program. Modified reciprocal teaching involved small groups of students working together to read and comprehend a portion of text. The students took turns “teaching” these groups by assisting the rest of the group in selecting key words and phrases, summarizing, questioning, clarifying, and predicting. Students were randomly assigned to one of three seventh-grade regular education social studies classes. One class used modified reciprocal teaching twice a week for 8 weeks. The other two classes received a traditional instructional program. All classes were taught by the same teacher. Significant differences included higher scores on comprehension tests and writing samples, improvement in second-quarter social studies grades, and better conduct records for students who participated in modified reciprocal teaching. Several explanations for the superior performance of the modified reciprocal teaching group are hypothesized. 相似文献

Flipped instruction, in which information typically conveyed through in-class lectures is delivered remotely through video or text, is being used increasingly by teachers at all levels. However, there is little research documenting how elementary teachers think about, plan for, and use flipped instruction. In this article, we use data from interviews, class observations, and an analysis of instructional videos to describe an elementary mathematics specialists' efforts to incorporate flipped instruction for mathematics in her fifth grade class. We use this case to highlight how a knowledgeable teacher might use flipped instruction to enhance her teaching, and also describe potential challenges. 相似文献

Abstract This randomized, controlled field trial estimated the causal impact of a technology-based geometry curriculum on students’ geometry achievement, as well as their attitudes toward mathematics and technology. The curriculum combines learner-centered classroom pedagogy with individualized, computer-based student instruction. Conducted over a 3-year period in eight high schools within an urban fringe district, the study found that students assigned to the treatment curriculum scored 19% of a standard deviation lower on the geometry posttest than their counterparts assigned to the district's standard curriculum, but found no statistically significant impact on students’ attitudes toward mathematics and technology. Researchers also collected observation and interview data on teachers’ instructional practices. These data suggest that many teachers had difficulty implementing the treatment curriculum's learner-centered pedagogy. In fact, observed levels of learner-centered practices were only modestly higher in treatment classes than in control classes. In both treatment and control classes, however, higher levels of learner-centered pedagogy were associated with higher student achievement in geometry. 相似文献

Abstract. Thirty‐four matched pairs of sixth‐ and seventh‐grade students were selected from 358 participants in a comparison of an explicit concrete‐to‐representational‐to‐abstract (CRA) sequence of instruction with traditional instruction for teaching algebraic transformation equations. Each pair of students had been previously labeled with a specific learning disability or as at risk for difficulties in algebra. Students were matched according to achievement score, age, pretest score, and class performance. The same math teacher taught both members of each matched pair, but in different classes. All students were taught in inclusive settings under the instruction of a middle school mathematics teacher. Results indicated that students who learned how to solve algebra transformation equations through CRA outperformed peers receiving traditional instruction on both postinstruction and follow‐up tests. Additionally, error pattern analysis indicated that students who used the CRA sequence of instruction performed fewer procedural errors when solving for variables. 相似文献

This study examined the interrelationships among three major components of classroom teaching: subject matter content knowledge, classroom management, and instructional practices. The study involved two middle school science classes of different achievement levels taught by the same female teacher. The teacher held an undergraduate degree with a major in social studies and a minor in mathematics and science from an elementary teacher education program. The findings indicated that the teacher's limited knowledge of science content and her strict classroom order resulted in heavy dependence on the textbook and students' individual activities (e.g., seatwork) and avoidance of whole-class activities (e.g., discussion) similarly in both classes. Implications for educational practices and further research are discussed. 相似文献

In this study we explored the relationship between teacher enjoyment of teaching mathematics, their attitudes towards student struggle, and the amount of time teachers spent teaching mathematics. Ninety-eight primary educators were surveyed regarding their attitudes and behaviors towards mathematics instruction. Hierarchical regression analyses revealed that teacher enjoyment of teaching mathematics explained variance in both teacher attitudes towards student struggle and instructional time spent on mathematics, even after relevant educator characteristics were accounted for. Findings suggest that teacher enjoyment of teaching mathematics in the early primary years has important implications for both the quality and quantity of mathematics instruction students receive. 相似文献

This investigation explores the effectiveness of a teacher preparation program aligned with situated learning theory on preservice science teachers' use of technology during their student teaching experiences. Participants included 26 preservice science teachers enrolled in a 2‐year Master of Teaching program. A specific program goal was to prepare teachers to use technology to support reform‐based science instruction. To this end, the program integrated technology instruction across five courses and situated this instruction within the context of learning and teaching science. A variety of data sources were used to characterize the participants' intentions and instructional practices, including classroom observations, lesson plans, interviews, and written reflections. Data analysis followed a constant comparative process with the goal of describing if, how, and why the participants integrated technology into their instruction and the extent to which they applied, adapted, and innovated upon what they learned in the science teacher preparation program. Results indicate that all participants used technology throughout their student teaching for reform‐based science instruction. Additionally, they used digital images, videos, animations, and simulations to teach process skills, support inquiry instruction, and to enhance student engagement in ways that represented application, adaptation, and innovation upon what they learned in the science teaching methods program. Participants cited several features of the science teacher preparation program that helped them to effectively integrate technology into their instruction. These included participating in science lessons in which technology was modeled in the context of specific instructional approaches, collaborating with peers, and opportunities for feedback and reflection after teaching lessons. The findings of this study suggest that situated learning theory may provide an effective structure for preparing preservice teachers to integrate technology in ways that support reform‐based instruction. © 2013 Wiley Periodicals, Inc.

The purpose of this study was to determine what effect the communication of precise instructional objectives to students has on their learning. The study was designed (1) to provide data on whether student achievement can be influenced significantly by providing students, in advance of instruction, information on what is expected of them as an outcome of instruction and (2) to investigate various ways of communicating to students, in writing, that which is to be learned in class. The Ss for this study were selected from five tenth-grade health and safety classes taught by the same teacher. Of the 143 Ss, one third in each class was randomly assigned to one of three treatment groups. For treatment groups one through three, the participants received precisely stated instructional objectives, vaguely stated instructional objectives, and short paragraphs of health information, respectively. Ss receiving prior to instruction precise information on what is expected of them showed greater achievement than those who received vague or related information. 相似文献

Co‐teaching is a popular strategy for implementing the inclusion of students with disabilities within secondary general education classrooms. However, we have little data regarding its effectiveness under routine conditions of educational practice. This study examined whether there was an “additive effect” of the special education teacher on the instructional experiences of students with disabilities as compared with the experiences of the same students taught by only the general education teacher under routine conditions. Observers used time sampling methods to document how students with disabilities spent their time in 11 middle school co‐taught classes. Statistically significant differences were found for targeted students in terms of general education teacher interaction and individual instruction. General education teachers spent significantly less time with students with disabilities when the special education teacher was present. In addition, students with disabilities received significantly more individual instruction when the special education teacher was present. However, these differences were of limited practical significance. 相似文献

Summary Was the project successful in assisting teachers to reform their biology teaching? The answer appears to be a qualifiedyes. Although teachers changed how they taught biology, they did not necessarily adopt the model as originally conceived by the
project. Teachers used materials they developed in ways that increased student involvement in learning and decreased direct
teacher instruction. Teachers taught primarily from the units they developed, and they borrowed instructional ideas and lessons
from other units which fit their instructional style and curriculum. Teachers did not, however, adopt complete instructional
units developed by other teachers for use in their classroom. 相似文献

Researchers in educational technology have searched for factors to explain teachers’ acceptance and resistance to using technology
for instruction. Among the many identified factors, however, organizational and school factors have not yet been explored
and discussed. This study investigates the effects of school size on science and mathematics teachers’ adoption of technology
in classrooms. Using national survey data collected from 940 science and mathematics teachers at junior high schools in Taiwan,
we employed factor analyses, log-linear analyses, and three-way ANOVA techniques to examine interactions among school factors
and teacher factors. Results obtained from the log-linear analyses suggested that both the interactions of school region with
school size and school size with technology users were needed to explain teachers’ use of educational technology in classrooms.
It appears that teachers at small schools were more likely to use technology for instructional purposes. Additionally, results
of the study revealed that teachers at small schools tended to have positive attitudes toward technology use and that among
users of educational technology in southern Taiwan, teachers at small schools designed and used significantly more instructional
activities with technology. This study suggests that small schools provide a better environment for science and mathematics
teachers to implement educational technology in instruction. 相似文献

As it has been shown that teachers of social studies content are less likely than teachers of other content areas to utilize technology in their classroom, this study focuses on one instructional technology coordinators’ beliefs towards technology, instruction, and students and how these beliefs impacted how technology was utilized during a technology-enriched community history project with a group of fourth-grade students. It was determined that the instructional technology coordinators’ beliefs included the following: (a) technology should serve as a tool and should be seamlessly integrated into the curriculum; (b) the teacher should construct meaningful experiences that allow students to become engaged in the learning process; however, before guiding student discovery, the teacher needs to explicitly teach basic technological skills; (c) and all students are able to learn and are capable of engaging in independent problem solving and critical thinking at some level. Her beliefs manifested themselves daily, particularly in the way that she approached instruction and integrated technology seamlessly into the curriculum. Through this study, it was found that the technology coordinator's beliefs toward technology, instruction, and her students directly impacted how technology was used in her classroom. 相似文献

Teacher characteristics and teaching styles as effectiveness enhancing factors of classroom practice
《Teaching and Teacher Education》2006,22(1):1-21
This study examined effects of teacher characteristics (gender, teacher education and certification, class management skills and job satisfaction) and teaching styles on indicators of good classroom practice in mathematics classes in secondary education by means of multilevel analysis. The study reveals that the presence of effective classroom practices can be explained by a learner-centered teaching style and by good class management skills. Furthermore, it was found that teachers with a high level of job satisfaction give more instructional support to their classes, especially to classes from a low-ability range, than teachers with a low level of job satisfaction. 相似文献

Science, technology, engineering, and mathematics (STEM) fields, important in today’s world, are underrepresented by students with disabilities. Students with visual impairments, although cognitively similar to sighted peers, face challenges as STEM subjects are often taught using visuals. They need alternative forms of access such as enlarged or audio‐converted text, tactile graphics, and involvement in hands‐on science. This project focused on increasing teacher awareness of and providing funds for the purchase of supplemental adaptive resources, supplies, and equipment. We examined attitude and instructional changes across the year of the programme in 15 science and mathematics teachers educating students with visual impairments. Positive changes were noted from pretest to posttest in student and teacher perspectives, and in teacher attitudes towards students with disabilities in STEM classes. Teachers also provided insights into their challenges and successes through a reflective narrative. Several adolescent students resisted accommodations to avoid appearing conspicuous to peers. Teachers implemented three strategies to address this: providing the adaptations to all students in the class; convincing the student of the need for adaptation; and involving the class in understanding and accepting the student’s impairment. A variety of teacher‐created adaptations for various science and mathematics labs are reported. Another finding was many adaptations provided for the student with visual impairment benefitted the entire class. This study supports the claim that given knowledgeable, supportive teachers, and with appropriate accommodations such as tactile or auditory materials, students with visual impairments can be as successful and engaged as other students in science and mathematics. 相似文献
