Accountability mandates often prompt assessment of student learning gains (e.g., value-added estimates) via achievement tests. The validity of these estimates have been questioned when performance on tests is low stakes for students. To assess the effects of motivation on value-added estimates, we assigned students to one of three test consequence conditions: (a) an aggregate of test scores is used solely for institutional effectiveness purposes, (b) personal test score is reported to the student, or (c) personal test score is reported to faculty. Value-added estimates, operationalized as change in performance between two testing occasions for the same individuals where educational programming was experienced between testing occasions, were examined across conditions, in addition to the effects of test-taking motivation. Test consequences did not impact value-added estimates. Change in test-taking motivation, however, had a substantial effect on value-added estimates. In short, value-added estimates were attenuated due to decreased motivation from pretest to posttest.  相似文献   

Discrimination of the number of sequential events by rats     

Donna M. Fernandes  Russell M. Church 《Learning & behavior》1982,10(2):171-176

Ten rats were trained to press a right lever following two successive sounds and to press a left lever following four successive sounds. Three sound sequences were used in initial discrimination training, such that reliable classification could not be based on the duration of each sound, the interval between sounds, or the total duration of the sound sequence. Classification of seven novel sound sequences suggested that the animals were either using number or the sum of sound durations in a sequence as the relevant cue. When this total sound duration was put in conflict with number, rats classified by number. The conclusion was that rats can discriminate number, even when temporal cues are controlled.  相似文献   

An exploration of teacher's use of iPads for students with learning support needs          下载免费PDF全文

This project explored how iPads were being used in a range of K‐12 schools to support the learning of students with a range of learning support needs. Groups of teachers (and other professionals) from the USA, Canada, Australia and the UK were invited to complete an online survey focused on the use of iPads in their classrooms, perspectives of their skill level, and how their school and school districts support the use of iPads. The survey focused on iPad use in classrooms (curriculum and skills); teachers’ skill levels; whether iPads are addressed in the Individualised Education Program (IEP); the systemic support for the iPads; and the perceived benefits and barriers. The results reveal that respondents are using iPads across many areas of the curriculum, which affirms the research in the emerging literature base. However, there are teacher reported differences in the manner and scope of iPad use in the classrooms and also the integration of the iPad in the IEP. The research also highlights variability in reported skill level for the iPad and an increased need for enhanced systemic support, such as training, funding, technical support and administrative support for the use of the iPad as a pedagogical tool.  相似文献   

Meta-analysis of theory-of-mind development: the truth about false belief   总被引：58，自引：0，他引：58  

Wellman HM  Cross D  Watson J 《Child development》2001,72(3):655-684

Research on theory of mind increasingly encompasses apparently contradictory findings. In particular, in initial studies, older preschoolers consistently passed false-belief tasks-a so-called "definitive" test of mental-state understanding-whereas younger children systematically erred. More recent studies, however, have found evidence of false-belief understanding in 3-year-olds or have demonstrated conditions that improve children's performance. A meta-analysis was conducted (N = 178 separate studies) to address the empirical inconsistencies and theoretical controversies. When organized into a systematic set of factors that vary across studies, false-belief results cluster systematically with the exception of only a few outliers. A combined model that included age, country of origin, and four task factors (e.g., whether the task objects were transformed in order to deceive the protagonist or not) yielded a multiple R of .74 and an R2 of .55; thus, the model accounts for 55% of the variance in false-belief performance. Moreover, false-belief performance showed a consistent developmental pattern, even across various countries and various task manipulations: preschoolers went from below-chance performance to above-chance performance. The findings are inconsistent with early competence proposals that claim that developmental changes are due to tasks artifacts, and thus disappear in simpler, revised false-belief tasks; and are, instead, consistent with theoretical accounts that propose that understanding of belief, and, relatedly, understanding of mind, exhibit genuine conceptual change in the preschool years.  相似文献   

Towards teaching science for social responsibility: An examination of flaws in science,technology and society     

Dr. Roger T. Cross  Dr. Ronald F. Price 《Research in Science Education》1991,21(1):47-54

In this paper we continue our search for a socially responsible science education by an examination of the trends in the Science, Technology and Society movement. These trends reflect differing ideological perspectives and result in courses which serve different ends. We identify two major flaws in the movement that inhibits the realization of a schooling in science dedicated to democracy. We propose skills necessary for citizens to participate in debate over issues surrounding the impact of science and technology on society and a teaching stategy to help develop them. Specializations: social responsibility and the curriculum, ideology and comparative science education.  相似文献   

Building Context: Using Activity Theory to Teach About Genre in Multi-Major Professional Communication Courses     

Donna Kain  Elizabeth Wardle 《Technical Communication Quarterly》2005,14(2):113-139

Instructors in multi-major professional communication courses are asked to teach students a variety of workplace genres. However, teaching genres apart from their contexts may not result in transfer of knowledge from school to workplace settings. We propose teaching students to research genre use via activity theory as a way of encouraging transfer. We outline theory and research relevant to teaching genre and provide results from a study using activity theory to teach genre in two different professional communication courses.  相似文献

No comparison: Distance education finds a new use for ‘No significant difference’     

Barbara B. Lockee  John K. Burton  Lawrence H. Cross 《Educational technology research and development : ETR & D》1999,47(3):33-42

Media comparison studies have long been criticized as an inappropriate research design for measuring the effectiveness of instructional technology. However, a resurgence in their use has recently been noted in distance education for program evaluation purposes. An analysis of the research design will detail why such a methodology is an inappropriate approach to such an investigation. Increased access to such programming does not seem to serve as a satisfactory benefit for the implementation of distance education efforts. Stakeholders desire to prove that participants in distance-delivered courses receive the same quality of instruction off-campus as those involved in the traditional classroom setting. However, the desire to prove that the quality of such distributed offerings is equal to the quality of on-campus programming often results in comparisons of achievement between the two groups of student participants. Statistically, such a research design almost guarantees that the desired outcome will be attained—that indeed distance learners perform as well as campus-based students.  相似文献

Exploring youth engagement in agricultural development: the case of farmers’ children in the Philippines as rice crop manager infomediaries     

Jaime A. Manalo IV  Sonny P. Pasiona  Anna Marie F. Bautista  Jennifer D. Villaflor  Donna Cris P. Corpuz  Hanah Hazel Mavi Biag-Manalo 《The Journal of Agricultural Education and Extension》2019,25(4):361-377

Purpose: This paper explores the intersections between community development and youth development in an initiative that mobilized farmers’ children as Rice Crop Manager (RCM) infomediaries (information mediators). RCM is an ICT-enabled nutrient management application.

Design/Methodology/Approach: The study engaged 30 farmers’ children in high school level from the provinces of Pangasinan, Isabela, Camarines Sur, Iloilo, Bukidnon, and Davao del Norte from November 2016 to October 2017. They interacted with the research team (the authors) and the RCM-SMS platform that sends text messages regarding fertilizer recommendations. A staff member from the Agricultural Training Institute (ATI) also called the students for some follow-up questions. The research team conducted three rounds of interviews with the students concerning the messages and calls that they received and what they did with the information.

Findings: This study finds that farmers’ children can perform infomediary roles quite effectively. Academically excellent children and those involved in farm work performed best.

Practical Implications: The study provides guidance on similar initiatives tapping young people in agricultural development.

Theoretical Implications: This paper finds that while Community Youth Development (CYD) Theory provides a powerful lens in understanding community and youth development intersections, some identified outcomes may overlap and may not be very easy to observe. Hence, the identified outcomes may be revisited for clarity and to make them more all-encompassing.

Originality/Value: The paper documents actual parent-child interaction when the latter is mobilized to serve as an infomediary to access nutrient management-related information on rice.  相似文献
