This study examines how three elementary teachers refer to pictorial models (photographs, drawings, and cartoons) during science read-alouds. While one teacher used realistic photographs for the purpose of visually verifying facts about crystals, another employed analytical diagrams as heuristic tools to help students visualize complex target systems (rainbow formation and human eye functioning). Another teacher used fictional cartoons to engage students in analogical storytelling, communicating animal camouflage as analogous to human “blending in.” However, teachers did not always explicitly convey the representational nature of pictorial models (analog and target as separate entities). It is argued that teachers need to become more aware of how they refer to pictorial models in children’s science books and how to promote student visual literacy. 相似文献

Abstract This paper is organized into two main sections. The first section examines extension as an engine for innovation and reviews the numerous priorities confronting extension systems. Section two highlights the current knowledge imperative and the critical connection of extension to post-secondary higher education and training, organizational inservice training, and vocationally oriented self-directed learning. Final comments address ‘The Continuing Role of the Public Sector’, and the prospect of its role in balancing societal interests and promoting extension as an aspect of a knowledge economy. The conclusion proposes what may be agricultural extension's challenges ahead. 相似文献

Abstract This study was designed to determine the value of the Southern Region Cooperative Extension Program Leadership Network in the United States. Of particular interest was determining the value added by the network for individual extension administrators, their state organizations, and the southern region. The researchers conducted a series of focus groups and an electronic survey of the members of the Southern Region Cooperative Extension Program Leadership Network to determine the value of the network. The Program Leadership Network was found to provide great value for the vast majority of study participants at the individual, team, and organizational levels. This value included enhancing individual performance, encouraging critical thinking, catalyzing best practices, providing opportunities for leadership and skill development, enhancing the relationship between extension programmes, and serving as a think tank for regional and national initiatives. Extension and programme administrators in other regions and countries should examine leadership networks to determine if they are adding value to extension work. Development of a network similar to the Southern Region Cooperative Extension Program Leadership Network could improve individual, team, and organizational effectiveness. This is especially true for enhancing multistate, regional, and national programming. Extension systems and workers will find value in this study since the results indicate that networking of extension workers enhances personal, team, and organizational performance. A secondary value includes the increased number of multistate, regional, and national coordination of extension programming efforts. 相似文献

In the flipped classroom model, the pedagogical paradigm is reversed and the students learn the class lesson at home and do homework in class. Although much of the focus of the flipped model has been on the secondary education level, this model could be a viable way to teach library instruction sessions to college-level students as well as a way to preserve scarce class time. This article examines a project that was done at LIU Post, where an instructor of the Library Competency Workshop course flipped the classroom and compared test results to sections where the class was run in a traditional lecture classroom model as well as the experiences on how the instructor flipped the classroom. 相似文献

Part of the mission of the American Association of Community Colleges addresses the need for a curriculum emphasis on international and intercultural education (Wismer, 1994, p. 77). Considering that (a) 2‐year colleges exist primarily to prepare students for jobs, (b) many American businesses operate in an international environment, and (c) a growing proportion of companies in the United States are foreign affiliated, the internationalization of our curriculums is necessaryforthe fulfillment of institutional missions of preparing the workforce for businesses. However, to fully internationalize college programs and services, the focus must be on more than courses and curriculums. The everyday life of college students, faculty, and staff must present evidence of cultural diversity. Internationalization, therefore, must be infused at every level of college activity. Such an infusion is occurring at Florence‐Darlington Technical College in Florence, South Carolina. There are four broad categories within which activities are planned or are underway: (a) resource development, (b) awareness development and information dissemination, (c) faculty and staff development, and (d) curriculum development. The importance of the need for this South Carolina college to undertake internationalizing initiatives is underscored by the multicultural business environment that exists in the state. For many years, international investment has created record levels of new employment opportunities for South Carolinians and has contributed significantly to statewide economic and industrial growth. The economic impact of international business in the state is apparent. However, there is also a cultural impact that is less obvious, yet profound. These factors present some definite implications for the need to internationalize technical college programs and services. 相似文献

Three experiments (N = 68), using Wynn's procedure, tested 5-month-old infants' looking time reactions to correct and incorrect results of simple addition and subtraction transformations. The aim was to investigate both the robustness and the parameters of infants' arithmetic competence. Experiments 1 and 2 (N = 44) were replications of Wynn's first two experiments in which infants were shown addition (1 + 1 = 1 or 2) and subtraction (2 - 1 = 1 or 2) requiring imprecise calculation. Experiment 3 (N = 24) was a subtraction counterpart (3 - 1 = 1 or 2) to Wynn's third experiment requiring precise calculation of addition (1 + 1 = 2 or 3). Unlike Wynn, we found no systematic evidence of either imprecise or precise adding and subtracting in young infants. Our results, together with the mix of both positive and negative findings from other studies of infant arithmetic, suggest that infants' reactions to displays of adding and subtracting are variable and, therefore, that infants' numerical competencies are not robust. This conclusion is consistent with previous findings indicating that simple adding and subtracting develops gradually and continuously throughout infancy and early childhood. 相似文献

An increase in online education is causing science educators to evaluate student cognitive understanding after completing virtual, computer-simulated laboratories. Online education has demonstrated comparable learning gains when analysed to those of the traditional classroom, but research is mixed when reviewing students’ ability to manipulate tangible laboratory equipment after participating in online experimentation. The question remains, are students who are exclusively enrolled in online science courses equipped with the cognitive ability to operate laboratory equipment within a physical laboratory? When considering the optimal learning environment for science majors, educators have discovered the blended classroom may provide the perfect opportunity to combine the benefits of face-to-face instruction and feedback with the reinforcement of scientific theory through technology integration. New advances in virtual education provide promising examples of enhancing the online classroom laboratory in all scientific disciplines. Further insight into the blended classroom has the potential to influence the field of education towards an optimal learning environment for science majors in colleges and universities. 相似文献

Team‐based projects continue to be important for structuring work in many organizations, and employees are increasingly using mobile applications (apps) for peer evaluations as part of a performance appraisals process. Since a graduating student can expect to work in a team at some point in their career, exposure to class‐related group projects is important. This study explored using a mobile application (app) called DevelapMe (DMe), which allowed for 273 business undergraduates in 54 teams to give and receive real‐time peer‐based feedback during a 5‐week group project. Prior empirical research has shown that technology can improve the group development process, but such research has not used a mobile app. The general goal of this study was to investigate how receiving real‐time feedback through a mobile app (DMe) can affect the team development process over time. Two online surveys, Time 1 (T1) and Time 2 (T2), were administered over a 5‐week period. Results showed that two of the three team‐level process outcomes, team trust and team commitment (but not team value‐goal fit), significantly increased from T1 to T2. Results also showed that receiving T1 sender‐based positive, but not negative, feedback scales had a significant impact on all three team‐level process outcomes. 相似文献

This paper provides an instrumental account of precalculus students’ graphical process for solving polynomial inequalities.
It is carried out in terms of the students’ instrumental schemes as mediated by handheld graphing calculators and in cooperation
with their classmates in a classroom setting. The ethnographic narrative relays an instrumental sociogenetic account of mathematical
knowledge construction and foregrounds a progressive evolution of mathematical knowledge from the concrete to the abstract
phase. 相似文献
