Constraints on conceptual development: a case study of the acquisition of folkbiological and folksociological knowledge in Madagascar     

Astuti R  Solomon GE  Carey S 《Monographs of the Society for Research in Child Development》2004,69(3):1-135, vii-viii; discussion 136-61

How different are the concepts held by children who grow up in a North American middle class neighborhood and by children who grow up in a rural Malagasy fishing village? By probing Malagasy children's and adults' conceptual representations of human and animal kind, biological inheritance, innate potential and family relations, the studies presented in this Monograph address current debates about the acquisition and the nature of concepts in the domains of folkbiology and folksociology. Cross-cultural and developmental studies of this kind bear on the hypothesis that conceptual development in these domains is supported and constrained by innate conceptual content. If so, one would expect cross-cultural universality in the relevant adult concepts and their early emergence in childhood regardless of widely different input conditions. We chose to conduct these studies among the Vezo of Madagascar because the ethnographic literature has attributed to them folkbiological and folksociological theories that are radically different, even in commensurable, with those of North American adults. Vezo therefore provide a challenging test for the innate conceptual constraints hypothesis.Four studies probed aspects of biological and sociological reasoning of Vezo children, adolescents and adults through a number of adoption scenarios. Despite ethnographic reports to the contrary, we found cross-cultural convergence in adult concepts of biological inheritance, but the pattern of development of this concept differed greatly from that seen in North America. Moreover, in agreement with the ethnographic literature, we found that Vezo adults have constructed a distinctive theory of social group identity. However, we found that children's reasoning in this domain is under the influence of endogenous constraints that are overturned in the course of development. Finally, we found cross-cultural convergence in adults' concept of species kind, as well as evidence for the early emergence of this concept. In light of these findings, we discuss the nature of the constraints on children's conceptual representations, the developmental process through which the adults' concepts are constructed, and relations between Vezotheories of folkbiology and folksociology.  相似文献   

A theory of instruction for introductory programming skills     

Benjamin Xie  Dastyni Loksa  Greg L. Nelson  Matthew J. Davidson  Dongsheng Dong  Harrison Kwik 《Computer Science Education》2019,29(2-3):205-253

ABSTRACT

Background and Context: Current introductory instruction fails to identify, structure, and sequence the many skills involved in programming.

Objective: We proposed a theory which identifies four distinct skills that novices learn incrementally. These skills are tracing, writing syntax, comprehending templates (reusable abstractions of programming knowledge), and writing code with templates. We theorized that explicit instruction of these skills decreases cognitive demand.

Method: We conducted an exploratory mixed-methods study and compared students’ exercise completion rates, error rates, ability to explain code, and engagement when learning to program. We compared material that reflects this theory to more traditional material that does not distinguish between skills.

Findings: Teaching skills incrementally resulted in improved completion rate on practice exercises, and decreased error rate and improved understanding of the post-test.

Implications: By structuring programming skills such that they can be taught explicitly and incrementally, we can inform instructional design and improve future research on understanding how novice programmers develop understanding.  相似文献   

Economic Sectors as Discursive Resources for Civil Society Collaboration     

Matthew A. Koschmann 《Communication quarterly》2016,64(4):410-433

This study explores the communication processes of civil society collaboration, with particular attention to the ways in which sectoral differences are managed communicatively and how sectoral differences among members are implicated in the processes of collaboration. Findings from a 10-month qualitative investigation of a civil society collaboration of social service providers indicate that sector differences are discursive resources that people draw upon to make sense of uncertainty and frame arguments. Findings also demonstrate how sector differences are managed communicatively through practices of recognition, resistance, translation, and mediation. This study builds on previous scholarship that conceptualizes civil society collaboration as a series of communicative processes and discursive practices (versus economic or structural characteristics), as well as research that advocates a processual approach to the study of organizational collaboration.  相似文献   

Understanding the graphical challenges faced by vision-impaired students in Australian universities     

Matthew Butler  Leona Holloway  Kim Marriott  Cagatay Goncu 《高等教育研究与发展》2017,36(1):59-72

Information graphics such as plots, maps, plans, charts, tables and diagrams form an integral part of the student learning experience in many disciplines. However, for a vision impaired student accessing such graphical materials can be problematic. This research seeks to understand the current state of accessible graphics provision in Australian higher education. We conducted an online survey of 71 vision-impaired university students and semi-structured interviews with 44 key stakeholders (students, academics, disability liaison officers and accessible graphics providers). We found that difficulty in accessing graphical materials was a barrier to many vision-impaired students and that there were systemic problems with current processes for accessible graphics provision. Recommendations are made on ways to address these concerns in order to provide a more equitable higher education experience.  相似文献

The Validity of Value-added Estimates from Low-Stakes Testing Contexts: The Impact of Change in Test-Taking Motivation and Test Consequences     

Sara J. Finney  Donna L. Sundre  Matthew S. Swain  Laura M. Williams 《Educational Assessment》2016,21(1):60-87

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

Development of the International Ocean Literacy Survey: measuring knowledge across the world.     

Géraldine Fauville  Craig Strang  Matthew A. Cannady  Ying-Fang Chen 《Environmental Education Research》2019,25(2):238-263

The Ocean Literacy movement began in the U.S. in the early 2000s, and has recently become an international effort. The focus on marine environmental issues and marine education is increasing, and yet it has been difficult to show progress of the ocean literacy movement, in part, because no widely adopted measurement tool exists. The International Ocean Literacy Survey (IOLS) aims to serve as a community-based measurement tool that allows the comparison of levels of ocean knowledge across time and location. The IOLS has already been subjected to two rounds of field testing. The results from the second testing, presented in this paper, provide evidence that the IOLS is psychometrically valid and reliable, and has a single factor structure across 17 languages and 24 countries. The analyses have also guided the construction of a third improved version that will be further tested in 2018.  相似文献   

Classroom Use of Multimedia-Supported Predict–Observe–Explain Tasks in a Social Constructivist Learning Environment     

Matthew Kearney 《Research in Science Education》2004,34(4):427-453

This paper focuses on the use of multimedia-based predict–observe–explain (POE) tasks to facilitate small group learning conversations. Although the tasks were given to pairs of students as a diagnostic tool to elicit their pre-instructional physics conceptions, they also provided a peer learning opportunity for students. The study adopted a social constructivist perspective to analyse and interpret the students conversations, focussing on students articulation and justification of their own science conceptions, clarification of and critical reflection on their partners views, and negotiation of new, shared meanings. Two senior science classes participated in this interpretive study. Data sources were mainly qualitative and included audio and video recordings of students small group discussions at the computer, interviews with selected students and their teachers, classroom observations, and student surveys. Findings indicate that the computer-based POE tasks supported students peer learning conversations, particularly during the prediction, reasoning and observation stages of the POE strategy. The increased level of student control of the POE tasks, combined with the multimedia nature of the program, initiated quality peer discussions. The findings have implications for authentic, technology-mediated learning in science.  相似文献   

Three-Dimensional Display Technologies for Anatomical Education: A Literature Review     

Matthew Hackett  Michael Proctor 《Journal of Science Education and Technology》2016,25(4):641-654

Anatomy is a foundational component of biological sciences and medical education and is important for a variety of clinical tasks. To augment current curriculum and improve students’ spatial knowledge of anatomy, many educators, anatomists, and researchers use three-dimensional (3D) visualization technologies. This article reviews 3D display technologies and their associated assessments for anatomical education. In the first segment, the review covers the general function of displays employing 3D techniques. The second segment of the review highlights the use and assessment of 3D technology in anatomical education, focusing on factors such as knowledge gains, student perceptions, and cognitive load. The review found 32 articles on the use of 3D displays in anatomical education and another 38 articles on the assessment of 3D displays. The review shows that the majority (74 %) of studies indicate that the use of 3D is beneficial for many tasks in anatomical education, and that student perceptions are positive toward the technology.  相似文献
