Toulmin’s argument pattern as a “horizon of possibilities” in the study of argumentation in science education

Kim and Roth (this issue) purport to draw on the social-psychological theory of L. S. Vygotsky in order to investigate social relations in children’s argumentation in science topics. The authors argue that the argumentation framework offered by Stephen Toulmin is limited in addressing social relations. The authors thus criticize Toulmin’s Argument Pattern (TAP) as an analytical tool and propose to investigate the genesis of evidence-related practices (especially burden of proof) in second- and third-grade children by studying dialogical interactions. In this paper, I illustrate how Toulmin’s framework can contribute to (a) the study of “social relations”, and (b) provide an example utilizing a theoretical framework on social relations, namely Engeström’s Activity Theory framework, and (c) describe how we have used the Activity Theory along with TAP in order to understand the development of argumentation in the practices of science educators. Overall, I will argue that TAP is not inherently incapable of addressing social relational aspects of argumentation in science education but rather that science education researchers can transform theoretical tools such as Toulmin’s framework intended for other purposes for use in science education research.  相似文献

The Effects of Role Congruence and Role Conflict on Work,Marital, and Life Satisfaction     

Kristin?M.?PerroneEmail author  L.?Kay?Webb  Rachel?H.?Blalock 《Journal of Career Development》2005,31(4):225-238

The impact of role congruence and role conflict on work, marital, and life satisfaction was studied using Super’s life-span, life-space theory. A conceptual model of relationships between these variables was proposed, and gender differences were examined. Participants were 35 male and 60 female college graduates who completed surveys by mail. Results indicated adequate fit for the proposed model. Results of gender analyses indicated that women in this study participated more in parenting and housework, whereas men participated more in career and leisure activities. Despite the differences in actual role participation, no gender differences were found regarding ideal role participation. Both men and women reported that the parent role was most rewarding. Implications for counselors and directions for future research were discussed.  相似文献   

Equilibrium bed-concentration of nonuniform sediment     

孙志林  孙志锋  DONAHUE John 《浙江大学学报(A卷英文版)》2003,4(2):186-194

Knowledge of the equilibrium bed-concentration is vital to mathematical modeling of the river-bed deformation associated with suspended load but previous investigations only dealt with the reference concentration of uniform sediment because of difficulties in observation of the bed-concentration. This work is a first attempt to develop a theoretical formula for the equilibrium bed-concentration of any fraction of nonuniform sediment defined at the bed-surface. The formula is based on a stochastic-mechanistic model for the exchange of nonuniform sediment near the bed, and described as a function of incipient motion probability, non-ceasing probability, pickup probability, and the ratio of the average single-step continuous motion time to static time. Comparison of bed-concentration calculated from the proposed formula with the measured data showed satisfactory agreement, indicating the present formula can be used for solving the differential equation goverming the motion of suspended load.

Academic Mentoring in College: The Interactive Role of Student’s and Mentor’s Interpersonal Dispositions     

Annie?BernierEmail author  Simon?Larose  Nathalie?Soucy 《Research in higher education》2005,46(1):29-51

This study examined the interaction between college students attachment orientation and mentors relational style in the prediction of students behaviors and perceptions in academic mentoring and of their subsequent academic achievement. Ninety college students were administered the Adult Attachment Interview and their professors-mentors completed the Attachment Style Questionnaire. Students displayed more adaptive behaviors and perceptions in mentoring and earned higher grades when their attachment orientation was in contrast to their mentors relational style. Implications for the practice of academic mentoring in college are discussed.  相似文献

Syllabic Sructures in Typing: Evidence from Deaf Writers     

Guido?NottbuschEmail author  Angela?Grimm  Rüdiger?Weingarten  Udo?Will 《Reading and writing》2005,18(6):497-526

This study examined the time course of typing in prelingually and profoundly deaf as well as hearing individuals. Both groups of participants performed a written picture naming task and a written pseudoword task. Keystroke timing measurements from the written picture naming task revealed that the deaf as well as the hearing group were significantly delayed at syllable boundaries compared to identical within-syllable letter combinations. As the deaf are impoverished with respect to phonology based on spoken language experience, we postulate that syllabic segmentation is not crucially dependent on experience with spoken language. Furthermore, delays at syllable boundaries were not affected by word frequency in both groups, in contrast to the keys straddling a root morpheme boundary. Together with the finding that delays at syllable boundaries also occur in pseudowords, the experiments provide strong evidence towards post-lexical syllabification processes. Our results support previous findings which claim that (1) orthosyllables are autonomous and mode-specific entities, and (2) that the principles of syllabic organisation apply post-lexically.  相似文献   

Existence of a new force in colloidal systems —Hydrophobic attraction between macroscopic surfaces     

B.?Sudhir  Sanjeev?KumarEmail author 《Resonance》2002,7(4):67-81

Colloids play an important role in our modern lives. In this article, we briefly discuss various forces that are known to operate between colloidal particles and then take the reader through the discovery of a new, strong and long ranged force operating between hydrophobic particles/surfaces. Characteristics of the new force and some promising theories proposed in the literature to explain its origin are also discussed; the origin of the new force is not yet resolved, however.  相似文献   

Representation of time in time-place learning     

Matthew?J.?PizzoEmail author  Jonathon?D.?crystalEmail author 《Learning & behavior》2002,30(4):387-393

Ordinal, interval, and circadian mechanisms of solving a time-place task were tested. Rats searched for food twice in the morning and once in the afternoon (Group AB-C,n=5) or once in the morning and twice in the afternoon (Group A-BC,n=5) in a box with four food troughs. The location of the food depended on the time of day in a 12:12-h light:dark cycle. Acquisition was documented by foodsite inspections at the correct locations prior to food availability. On nonrewarded probes, the time of the middle search (B) was shifted late (for Group AB-C) or early (for Group A-BC). The rats visited Location B at chance, contrary to an ordinal mechanism. When the posttesting meal and light-dark transitions were omitted, the rats visited correct locations with impaired performance but at abovechance levels on nonrewarded probes. The results are consistent with interval and circadian representations of time.  相似文献   

Heterogeneous UV/Fenton catalytic degradation of wastewater containing phenol with Fe-Cu-Mn-Y catalyst     

郑展望  雷乐成  徐生娟  岑沛霖 《浙江大学学报(A卷英文版)》2004,5(2):206-211

The heterogeneous UV/Fenton process with the appropriate amount of Fe-Mn-Cu-Y as catalyst was developed and various operation conditions for the degradation of phenol were evaluated. The results indicated that by using the heterogeneous UV/Fenton process, the CODcr removal rate reached almost 100% for wastewater containing phenol. Compared with the homogeneous process, the developed catalyst could be used at wider pH range in the UV/Fenton process. Comparison of various heterogeneous process showed that heterogeneous UV/Fenton process was best. The heterogeneous UV/Fenton process with Fe-Mn-Cu-Y catalyst is highly efficient in degrading various organic pollutants.  相似文献
