逻辑基本规律的新表述及其应用

伟大的逻辑学家亚里士多德提出了逻辑的三个基本规律：同一律、矛盾律和排中律,然而逻辑基本规律的现有表述并不科学。史天治提出了广义矛盾律,同时对逻辑基本规律进行了新的表述。新表述由三个部分组成：一是公式,二是客观规律,三是思维法则。同一律适用于词和命题,矛盾律和排中律仅适用于矛盾命题,广义矛盾律适用于互斥性命题。表达逻辑基本规律应以客观的语言形式（词和命题）为基础,而不是以主观的思想事物（概念、判断、推理）为基础。论文利用逻辑基本规律解决了说谎者悖论和罗素悖论。     

Alternative conceptions in Galilean relativity: inertial and non‐inertial observers

This concluding part of a study on Galilean relativity focuses on students’ notions with regard to the inertial and non‐inertial character of frames of reference. (See Panse et al. 1994, Ramadas et al. 1996). The results show that students: adopt kinematic criteria for deciding the inertial or non‐inertial character of frames; consider this character to be a ‘relative’ property of two frames rather than an intrinsic property of a given frame; and equate pseudo‐forces to ‘imaginary’ forces. Centrifugal force is associated with rotating objects rather than with rotating frames; the latter are localized by the finite extension of their associated objects. Anthropomorphic criteria are invoked to judge the existence of centrifugal force, which is regarded as a reaction (in the sense of Newton's third law) to the centripetal force on a rotating object.     

Judges’ delivery of ground rules to child witnesses in Australian courts

Ground rules directions are given to children in forensic interviews to explain what is expected of them, and to reduce their tendency to acquiesce to erroneous or incomprehensible questions. Ground rules may also be necessary when children provide testimony in court. Drawing on research conducted for the Australian Royal Commission into Institutional Responses to Child Sexual Abuse, the present study examined the use of ground rules directions delivered in court in 52 trials by 24 presiding judges in three jurisdictions to 57 child complainants (aged 7–17.5 years). Eleven categories of rules were identified. The number of words spoken to deliver each rule was counted, and grade-level readability scores were calculated as a proxy for the complexity of the ground rules. When judges asked comprehension or practice questions, the question types were coded. More than one third of the children (35%) received no ground rules directions from the judge; the remaining 65% received directions on an average of 3.5 types of ground rules out of a maximum of 11 types. While comprehension questions were common, practice questions were rare. Comprehension questions were most often presented in a yes/no format that implied the expected response, although this form of question is unlikely to provide an effective assessment of a child's comprehension. Neither the number of rules delivered nor the number of words used was related to children's age. Implications for children's court testimony are discussed.     

Executive function and verbal self-regulation in childhood: Developmental linkages between partially internalized private speech and cognitive flexibility

Recent studies have noted that executive function and the use of self-regulatory private speech are related in childhood, and proposed that the critical leap that occurs in the development of executive function between the ages of three and six years may be due to the onset of language-based self-regulatory functions at this age. This research explored the relationship between executive function and private speech in a cross-sectional study of 81 children between four and seven years of age. The children performed an executive function task, the Dimensional Change Card Sort (DCCS), and children's use of private speech was observed during a categorization task. The results indicated that, after controlling for children's age, gender, verbal abilities, and fluid reasoning, children's use of partially internalized private speech during the categorization task was significantly related to the number of phases successfully passed on the DCCS task, which required them to switch between card sorting rules. Children who used more partially internalized private speech were more likely to pass the most challenging phase of the DCCS task that assesses the ability to flexibly use different sorting rules according to a higher-order rule. We discuss the role of verbal mediation in the development of cognitive flexibility and its implications for the design of intervention programs for children who possess deficits of executive function.     

Mentoring and being mentored: The story of a novice music teacher's success

This qualitative study examined the growth of Jelani, a failing novice teacher who successfully received tenure following his third year of teaching. His progress seemed related to the quality of his relationships with different mentors. An unanticipated factor in Jelani's success was his participation in a university-based program for children, where he served, under supervision, as a mentor for two preservice teachers. In what became a mutually beneficial relationship, Jelani reinforced his new-found knowledge and skills and learned to better describe and assess his own teaching. Among those who worked with Jelani, additional reciprocal mentoring relationships developed.

Children's Thoughts About Reading and Spelling

Most current psychological research on children's reading concentrates either on the various abilities that children need to read or write or on the relative success of different kinds of instruction. Very little attention is being paid to the ways in which children learn orthographic rules. I argue that children typically go through 3 steps in learning a new rule. First they apply a rule that is already in their repertoire but is inadequate. Next, when they realize that this rule is inadequate, they try to extend and adjust it to cover these inadequacies. This adjustment leads them into new experiences that allow them to take the third and final step, which is to form a new and more adequate rule. These steps are similar to the theoretical sequence proposed by Piaget for children's construction of logical rules.     

Support of the collaborative inquiry learning process: influence of support on task and team regulation

Regulation of the learning process is an important condition for efficient and effective learning. In collaborative learning, students have to regulate their collaborative activities (team regulation) next to the regulation of their own learning process focused on the task at hand (task regulation). In this study, we investigate how support of collaborative inquiry learning can influence the use of regulative activities of students. Furthermore, we explore the possible relations between task regulation, team regulation and learning results. This study involves tenth-grade students who worked in pairs in a collaborative inquiry learning environment that was based on a computer simulation, Collisions, developed in the program SimQuest. Students of the same team worked on two different computers and communicated through chat. Chat logs of students from three different conditions are compared. Students in the first condition did not receive any support at all (Control condition). In the second condition, students received an instruction in effective communication, the RIDE rules (RIDE condition). In the third condition, students were, in addition to receiving the RIDE rules instruction, supported by the Collaborative Hypothesis Tool (CHT), which helped the students with formulating hypotheses together (CHT condition). The results show that students overall used more team regulation than task regulation. In the RIDE condition and the CHT condition, students regulated their team activities most often. Moreover, in the CHT condition the regulation of team activities was positively related to the learning results. We can conclude that different measures of support can enhance the use of team regulative activities, which in turn can lead to better learning results.     

Beginning readers' use of talking books: styles of working

This paper examines young children's working styles when they are engaged with a peer on a computer‐based reading task. Two types of pairing were investigated: (i) ‘Equal’ pairs, where the children were of equal reading attainment and (ii) ‘Unequal pairs’, where there was a disparity between the children's reading attainment. The results suggest that the children's reading attainment and/or their gender may be more significant factors in determining the nature of children's collaborative activity than pair type. The implications of these results for practitioners who wish to use talking books as a classroom resource are discussed.     

Mothers' sensitivity to the competencies of their preschoolers on a concept-learning task

This study investigated the instructional strategies mothers used when interacting with their child on a concept-learning task and the effect of this interaction on subsequent independent child performance. Also investigated was whether mothers' behaviors and perceptions differed depending on the child's age, task difficulty, or the child's needs for assistance. Sixty 3- and 5-year-old children participated in a three-phase sequence of tasks that required the matching of opposite concepts. The pretest and posttest phases were identical for all children, but during the second phase half the children completed the tasks with their mothers and half continued to work independently. During each phase, children received both an easy and a difficult version of the task. Children who interacted with their mothers matched more concepts correctly on the posttest and gave more correct explanations for their matches than children who worked independently. Mothers of 3-year-olds provided more assistance than mothers of 5-year-olds, and mothers provided higher levels of assistance on the difficult task than on the easy task. Most mothers were sensitive to their child's needs in that the instructional strategies they adopted throughout the interaction were appropriately modified in response to their child's successes and failures. There was some evidence that individual differences in maternal sensitivity were related to variations in children's independent performance. Mothers' perceptions of the task, of their child's needs for assistance, and of their own role in the interaction were related to their overt behaviors. Intervention programs aimed at fostering parents' skills in interacting with their children should emphasize the importance of scaffolded instruction tuned to the child's capabilities.     

Rule-governed approaches to physics: Conservation of mechanical energy

This article reports on a study conducted to investigate the methods individuals use to make predictions about five situations involving the conservation of mechanical energy. The subjects in the study came from two different populations—science majors and nonscience majors. The technique used to determine the strategies subjects employed was a paper-and-pencil version of Siegler's Rule-Assessment technique. Each subject worked five task sets, although the order in which they did the sets varied. The task sets had simple situations involving carts moving on inclines or horizontal paths. The situations had energy transformations from: (1) kinetic energy to thermal energy via work against friction, (2) potential energy to thermal energy via work against friction, (3) potential energy to potential energy, (4) potential energy to kinetic energy, and (5) kinetic energy to potential energy. The major findings of the study were: (a) the subjects did employ identifiable strategies in over 97% of the cases, (b) the sequencing of the task sets did affect the way subjects worked the problems, (c) there was a difference in the way science majors and nonscience majors worked the problems, and (d) the effect of the variation in sequence differed for the two populations.     

Social marking of cognitive operations. The effect of different social rules

The present study is concerned with assessing whether social marking (i.e. the correspondence between the correct solution of a task and some known social rule) is a mechanism of cognitive progress which depends on specific forms of rule represented in the task material. Results of an experiment on a spatial transformation task (N=sixty-four non-conserving 5–6-year-olds) showed no significantly different levels of cognitive progress for subjects who transformed the spatial arrangement of a classroom or of a theatre. Significant difference emerged only when a deviation from the normally regulated arrangement were represented. In the condition where the deviation concerned the theatre subjects showed the lower level of progress. It was concluded that the beneficial effect of social marking may depend on the form of rule represented. Results were discussed with respect to children’s knowledge of the relative alterability of different types of rules.

Assessment and Learning of Qualitative Physics in Newton's Playground

ABSTRACT

Digital games are very popular in modern culture. The authors are examining ways to leverage these engaging environments to assess and support student competencies. The authors examine gameplay and learning using a physics game they developed called Newton's Playground. The sample consisted of 167 eighth- and ninth-grade students who played Newton's Playground for about 4 hr over the course of 1.5 weeks. Findings include significant pretest–posttest physics gains, and significant relations between in-game indicators and learning.     

Processes and Consequences of Peer Collaboration: A Vygotskian Analysis

A sample of 162 children aged from 5 to 9 was pretested to discover each child's "rule" for predicting the movement of a mathematical balance beam. Children then worked alone, with a partner who used the same rule, with a partner who was more competent, or with a partner who was less competent. If partners' predictions differed, the dyad members were asked to discuss and reach agreement, but were not given feedback. All children were subsequently given 2 individual posttests. The results revealed that regression in thinking was as likely a consequence as improvement, both proving stable. Benefits accrued primarily to those whose partner was more competent, but understanding of the outcomes of collaboration required attending both to the nature of the rules (whether they allowed consistent or inconsistent prediction) and the shared understanding attained during the paired session.     

The predictive power of intuitive rules: A critical analysis of the impact of `more A–more B' and `same A–same B'

In the international community of mathematics and science educators the intuitive rules theory developed by the Israeli researchers Tirosh and Stavy receives much attention. According to this theory, students' responses to a variety of mathematical and scientific tasks can be explained in terms of their application of some common intuitive rules. Two major intuitive rules are manifested in comparison tasks: ‘More A—more B’ and ‘Same A—same B’. In this paper, we address two important questions for which the existing literature on intuitive rules does not provide a convincing research-based answer: (1) are the reasoning processes of students who respond in line with a given intuitive rule actually affected by that rule or by essentially other misconceptions (leading to the same answer), and (2) are individual students consistent in their choice of one of the intuitive rules when confronted with different, conceptually unrelated tasks? A test consisting of five comparison problems from different mathematical subdomains was administered collectively to 172 Flemish students from Grades 10 to 12. An analysis of students' written calculations and justifications suggested that the students were considerably less affected by the intuitive rules than their multiple-choice answers actually suggested. Instead, essentially different misconceptions and errors were found. With respect to the issue of individual consistency, we found that students who made many errors did not answer systematically in line with one of the two intuitive rules.     

Identity concept formation during visual multiplechoice matching in a harbor seal (<Emphasis Type="Italic">Phoca vitulina</Emphasis>)

Identity concept formation was tested in a harbor seal using a visual multiple-choice matching-tosample task. The seal was first trained on a two-alternative matching task. After criterion (≥80% correct choices in two successive sessions) was reached with two sets of two stimuli (Figure 3, Blocks A and B), stimulus sets were enlarged to six objects (Blocks C-G). After the seal reached criterion immediately with two successive sets (Blocks F and G), multiple-choice matching was introduced, first using stimulus sets of four familiar objects (Blocks H-M). After the seal reached the criterion immediately with two successive sets (Blocks L and M), completely new objects were used in two further stimulus sets (Blocks N and O). The seal immediately applied the matching rule in all four sessions (≥80% correct choices). In two further sessions with problems composed of all 38 familiar stimuli, the seal again reached the criterion (Block P). In the final, transfer session, 20 new problems were composed of 80 unknown stimuli (Block Q). The seal immediately applied the matching rule in these one-trial tests, showing that harbor seals can conceptualize complex visual information.     

Peer Collaboration on a Nonverbal Reasoning Task by Urban,Minority Students

An experimental study of collaborative reasoning in 86 7th-grade minority students from an urban, low-income school was conducted. The students completed items from the Test of Nonverbal Intelligence-Third Edition (TONI-3) and were asked to provide written explanations for their judgments. All students worked individually during the pretest and posttest phases of the study. During the experimental phase, some students worked independently while others worked in small, same-gender or mixed-gender groups. Significant improvements in judgments were evident during the experimental phase for all groups except the single-gender female group. The mixed-gender group reached the ceiling level of performance and outperformed both the students who worked independently and the collaborative, single-gender female group during the experimental phase. Posttest judgment scores declined and were not significantly different from pretest scores for any group. Significant improvements in written explanations for judgments were evident during the experimental phase and were maintained on the posttest by all groups. The students who collaborated had higher percentages of fully correct explanations on the posttest than students who worked alone. Collaborative experiences were beneficial for students' reasoning about unfamiliar, moderately difficult, nonverbal problems.
