This article reports on a study in which activity theory was used to design, implement, and analyze a 10-week curriculum unit about how honeybees collect nectar with a particular focus on complex systems concepts. Students (n = 42) in a multi-year kindergarten and 1st-grade classroom participated in this study as part of their 10 regular classroom activity. The curricular unit was composed of 4 specific activity types, each of which was intended to focus students on a particular dimension of the content: (a) Inquiry with BeeSign software was intended to help students explore the benefit of individual nectar-collecting behaviors for the hive as a whole; (b) traditional drawing activities were intended to help students learn the structures of 15 the bees; (c) participatory representation activities, in which students enacted the behavior of the bees as they collect nectar, were intended to help students link bee structures to individual behaviors; and (d) an embodied nectar-gathering game was intended to help the students recognize the challenges of finding nectar for individual bees. Pre- and posttest interviews reveal a shift in individual student understanding 20 as students progressed from discussing the superficial structures of the system to discussing both behaviors and functions.  相似文献

Students with specific learning disabilities (SLDs) are more likely to exhibit internalizing and externalizing behaviors than typically developing peers. Virtually none of the literature, however, reports on the behaviors of students at-risk for writing disabilities (AR-WD). We compared the behaviors of writers who are AR-WD and typically developing writers (TDW) from first through fourth grade (N = 138). We found that students who are AR-WD were only significantly different from TDW on Externalizing and Total Behaviors at Grade 2. These findings illustrate the benefits of studying behavior across different forms of SLD, as it appears that students ARWD do not consistently manifest significant behaviors, although interventions that simultaneously target writing and behavior may be warranted and mutually beneficial.  相似文献

Research Findings: This study investigates contributions of the preschool classroom interpersonal environment to students’ social competence in 1st grade. Participants were 862 ethnically/racially diverse children who attended public preschool classrooms serving low-income families. Systematic observations of 60 classrooms occurred across the preschool year and quantified teacher and student behaviors. Preschool and 1st-grade teachers provided reports of children’s social behavior. First-grade teachers also assessed children’s problem behaviors. Multilevel analyses indicated that at the end of 1st grade, students who experienced preschool settings with teachers who displayed more approving behavior, less disapproving behavior, and more positive emotional tone showed significant gains in positive social behavior and lower rates of problem behavior, even after students’ social skills at preschool entry were controlled. Greater gains in positive social behavior and fewer problem behaviors in 1st grade were also predicted by immersion in preschool classrooms that had more positive and cooperative interactions among peers. Practice or Policy: Universal preschool is a policy under consideration nationally and locally, with social competence often listed as an important goal. This study indicates that even in the absence of a particular social-emotional curriculum, preschool teachers’ behaviors and interactions among their students may have lasting implications for children’s social development.  相似文献

School-wide positive behavior interventions and supports (SW-PBIS) can effectively reduce problem behaviors and simultaneously increase pro-social behaviors in general education settings. SW-PBIS is not a “packaged” intervention, but a framework through which schools create systemic changes for promoting expected behaviors, while also monitoring and intervening with students who have behavior concerns through a tiered model of service delivery. A case study documenting the SW-PBIS implementation process in an alternative educational setting is presented. Alternative schools typically serve students who qualify to receive special education services, have a lower staff-to-student ratio, and often warrant more intensive student interventions as compared to general education settings. These differences from traditional environments pose unique challenges to the SW-PBIS implementation process. Suggestions for neutralizing these challenges such as providing enhanced Tier 1 supports and extensive staff training are explained in depth in this case study.  相似文献

This study describes the effects of ability-paired student interactions on achievement as fifth graders (10-year-olds) worked on laboratory activities relating to balance. Achievement gains were assessed (n = 83) by analysis of pretest–posttest differences on the lever concept test. Audio recordings and field notes (n = 30) were analyzed for the following laboratory behaviors: number of words spoken, tinkering, block moving, turns speaking, incidence of helping and distracting behavior. Results revealed that: (1) low-ability student achievement is greater when students are paired with high-ability partners; (2) low-ability students speak more words, exhibit less distracting behavior, and move blocks on the lever less when they are paired with a partner of high ability; (3) high-ability students speak more words, take more turns speaking, and exhibit more helping behaviors when they are paired with low-ability students rather than with other high ability students; and (4) there are no achievement differences for high-ability students regardless of the ability level of their partner. These findings suggest that heterogeneous grouping of students in science can be beneficial to low-ability students partnered with high-ability students, without being detrimental to the high-ability partners.  相似文献

Three computer‐based systems for teaching arithmetic and algebra are discussed. The systems embody several pedagogical tactics: To provide students with augmented repre‐sentations that reveal the structure of problem solutions; to make mathematical symbols meaningful by giving students concrete referents for those symbols; to provide students with enriched feedback about the consequences of their mathematical operations; and to adapt instruction to the cognitive processes of the students. Weaknesses in the three systems are discussed and two general problems, called complexity trade‐off and scaffold removal, are put forward as possible explanations for why the systems are not more effective. The alternative view that mathematics is difficult because it requires abstract thinking is outlined and some of its implications discussed briefly.  相似文献

Data were collected from students in grades three to eight (N = 377) in order to identify the determinants of their intentions to perform laboratory and nonlaboratory science activities. Fishbein and Ajzen's theory of reasoned action was used as the basis for the study. The theory posits that the immediate determinant of behavior is intention. Intention is determined by the weighted attitude toward the behavior and the weighted subjective norm. Attitude toward behavior and subjective norm are determined by combinations of beliefs, evaluations, and motivations to comply. Cores of salient beliefs related to attitude toward laboratory and nonlaboratory behaviors and cores of salient beliefs related to subjective norm for laboratory and nonlaboratory behaviors were identified. Hypotheses generated from the theory were confirmed. Attitude toward behavior and subjective norm explained significant amounts of variance in behavioral intention for both laboratory and nonlaboratory behaviors. Attitude toward behavior had a greater relative weight than subjective norm for both laboratory and nonlaboratory. The correlations between adjacent constructs in the theoretical model were significant in all cases.  相似文献

This study explores interactions with diagrams that are involved in geometrical reasoning; more specifically, how students publicly make and justify conjectures through multimodal representations of diagrams. We describe how students interact with diagrams using both gestural and verbal modalities, and examine how such multimodal interactions with diagrams reveal their reasoning. We argue that when limited information is given in a diagram, students make use of gestural and verbal expressions to compensate for those limitations as they engage in making and proving conjectures. The constraints of a diagram, gestures and linguistic systems are semiotic resources that students may use to engage in geometrical reasoning.  相似文献

The purpose of this study is to investigate and compare students’ collaborative inquiry learning behaviors and their behavior patterns in an augmented reality (AR) simulation system and a traditional 2D simulation system. Their inquiry and discussion processes were analyzed by content analysis and lag sequential analysis (LSA). Forty university students were divided into dyads and then randomly assigned into AR group and traditional 2D group to collaboratively conduct an inquiry task about elastic collision. The results of the content analysis and LSA indicated that both systems supported students’ collaborative inquiry learning. Particularly, students showed high frequencies on higher-level inquiry behaviors, such as interpreting experimental data or making conclusions, when using these two simulations. By comparing the behavioral patterns, similarities and differences between the two groups were revealed. The AR simulation engaged the students more thoroughly in the inquiry process. Moreover, students in both groups adopted the same approaches to design experiments. Due to the line of AR research is in its initial stage, suggestions for future studies were proposed.  相似文献

In this study, 188 master‐level students received training through a distance education course to conduct functional behavioral assessments (FBAs) and behavior support plans with 68 boys and six girls (aged 3–20 years) displaying persistent behavior problems in inclusive preschools, elementary, and secondary schools. In the course, master‐level students’ scores on an FBA knowledge test increased from 13.2% to 68.8% correct. Changes in pupils’ target behaviors were evaluated with a total of 114 AB single‐subject designs and combined data with one‐group pretest–posttest designs. Comparing medians of means, disruptive behaviors decreased by 77.8% and aggressive behaviors by 88.7%, whereas task engagement increased by 91.5% after intervention. Nonparametric Wilcoxon signed‐ranks tests for related samples showed that changes were statistically significant for all groups with sufficient sample sizes. Adjusted effect sizes ranged from d = .5 to 1.6. Results indicate that positive changes in student behavior problems can be attained with function‐based interventions conducted by teams trained through a distance education course.  相似文献

Student behavioral concerns are a top priority for school psychologists. This project took an ecological systems perspective by examining the contribution of students’ initial externalizing and internalizing behaviors and the quality of their classroom environments to their behavioral outcomes across one school year. Participants included 322 elementary students and their 32 teachers. Results suggested that externalizing and internalizing behaviors were stable over time. However, the correlation between fall and spring internalizing behavior was accentuated if students also had high externalizing behavior in the fall. Poor spring behavioral engagement was predicted by students’ fall internalizing (but not externalizing) behavior. Importantly, classrooms high in emotional support attenuated the stability of students’ internalizing behavior. In addition, students’ fall externalizing behavior appeared to be associated with reduced spring internalizing behavior in classrooms high in emotional support or classroom organization. Findings underscore the importance of considering both student‐ and classroom‐level factors when predicting elementary students’ behavioral outcomes.  相似文献

This secondary analysis explored longitudinal associations between the concentration of shared-language peers and the development of prosocial and problem behavior in dual language learning (DLL) preschoolers from low socioeconomic backgrounds. Mixed-effects regression models were used to analyze year-end outcomes of 212 Spanish-speaking students in 73 Head Start classrooms in which English was the only instructional language. Research Findings: Classroom concentration of Spanish speakers was not associated with Spanish-speaking DLLs’ year-end prosocial behavior. For problem behavior, there was a disordinal interaction between teacher social-emotional support and classroom concentration. In classrooms with higher teacher social-emotional support, the proportion of Spanish-speaking classmates was positively associated with Spanish-speaking children’s problem behaviors. In classrooms with lower teacher social-emotional support, the proportion of Spanish-speaking students per classroom was negatively associated with Spanish-speaking children’s problem behaviors. Practice or Policy: Findings highlight the value of shared-language peers in particular classroom contexts and have implications for DLL students’ preschool classroom placements.  相似文献

Whereas emerging technologies, such as touchscreen tablets, are bringing sensorimotor interaction back into mathematics learning activities, existing educational theory is not geared to inform or analyze passages from action to concept. We present case studies of tutor–student behaviors in an embodied-interaction learning environment, the Mathematical Imagery Trainer. Drawing on ecological dynamics—a blend of dynamical-systems theory and ecological psychology—we explain and demonstrate that: (a) students develop sensorimotor schemes as solutions to interaction problems; (b) each scheme is oriented on an attentional anchor—a real or imagined object, area, or other aspect or behavior of the perceptual manifold that emerges to facilitate motor-action coordination; and (c) when symbolic artifacts are introduced into the arena, they may both mediate new affordances for students’ motor-action control and shift their discourse into explicit mathematical re-visualization of the environment. Symbolic artifacts are ontological hybrids evolving from things with which you act to things with which you think. Students engaged in embodied-interaction learning activities are first attracted to symbolic artifacts as prehensible environmental features optimizing their grip on the world, yet in the course of enacting the improved control routines, the artifacts become frames of reference for establishing and articulating quantitative systems known as mathematical reasoning.  相似文献

As school psychologists are asked to help schools evaluate the level of violence risk posed by specific students, they need to fully consider the technical adequacy of any test or procedure that is proposed to “predict” future violent behavior or conditions. In this article, we contribute to this discussion by examining responses of 40,435 students from the 1993, 1995, and 1997 administrations of the Youth Risk Behavior Surveillance Survey. Student self‐reported school risk behaviors and experiences are used to “predict” recent weapon possession on school campuses and to illustrate the use of receiver operating characteristic curves to evaluate the performance of a test for prediction purposes. An index of nine school risk behaviors was moderately correlated (r = .36) with school weapon possession. However, when the accuracy of using this school risk index to predict weapon possession is evaluated, it is found that the area under the ROC curve was approximately .75, a moderate‐to‐large effect size but still demonstrating inadequate prediction at the individual student level. Further, there were twice as many frequent weapon carriers with zero school risks than with 7–9 risks, suggesting that attention directed toward violence risk profiles may promote inattention to another group of students who engage in potentially high‐risk behaviors at school. It is argued that school psychologists should consider school violence appraisals within a developmental, long‐term model. © 2001 John Wiley & Sons, Inc.  相似文献

Abstract

The purpose of this study was to investigate objectively observable categories of behavior for good and poor readers in classroom settings. Seven specific observable behaviors of 3 good and 3 poor readers from each of three regular classrooms at each of six grade levels were viewed under natural classroom conditions. Trained observers recorded student behavior for 30 min a day for 10 days. A two-way analysis of variance procedure was used in data analysis. Results indicated that poor readers did not differ from good readers in starting to work on assignments, having necessary materials available, making unacceptable noise, being out of place, or making unacceptable contact with other persons or their property. Poor readers, however, were off task more and volunteered less than good readers did. The results were interpreted to suggest that poor readers could be viewed as uninvolved students. Instructional suggestions are given.  相似文献

This work compares the results of three assessment systems used in two Spanish universities (the Universidad Politécnica de Madrid and the Universidad Católica de Ávila): the traditional system based on final examinations, continuous assessment with periodic tests and a proposed system (specially designed for heterogeneous student bodies) orientated towards motivating students. This third system involved dividing the syllabus into two different parts: a common core assessed by multiple choice tests, and a specialisation assessed by a literature review, the writing of an article and an oral presentation. The latter skills are highly valued by employers. The proposed system led to a greater pass rate than that achieved by students taking similar courses assessed by the more conventional systems. In addition, the results show that involving students in the assessment process increases their participation in their studies and generates a feeling of satisfaction and justice.  相似文献

Relatively little is known about the extent of marijuana use and related risk‐taking behavior by college students on historically Black colleges and universities (HBCUs). Undergraduate students (N = 212) from an HBCU in the southern region of the United States completed anonymous questionnaires that assessed their marijuana‐related behaviors and perceptions. Logistic regression analysis revealed risk factor profiles that provide college counselors with greater insight into prevention and treatment on HBCU campuses.  相似文献
