RESUMO
Young adults received information regarding the platforms of two candidates for mayor of a troubled city. Half constructed a dialogue between advocates of the candidates, and the other half wrote an essay evaluating the candidates' merits. Both groups then wrote a script for a TV spot favoring their preferred candidate. Results supported our hypothesis that the dialogic task would lead to deeper, more comprehensive processing of the two positions, and hence a richer representation of them. The TV scripts of the dialogue group included more references to city problems, candidates' proposed actions, and links between them, as well as more criticisms of proposed actions and integrative judgments extending across multiple problems or proposed actions. Assessment of levels of epistemological understanding administered to the two groups after the writing tasks revealed that the dialogic group exhibited a lesser frequency of the absolutist position that knowledge consists of facts knowable with certainty. The potential of imagined interaction as a substitute for actual social exchange is considered.

We examined apprenticeship, in the form of interaction with a more capable other, as a mechanism of development of higher-order reasoning skills, specifically argumentation. Over a 1-year period, middle school students engaged in twice-weekly electronic dialogs with a sequence of different peers on a series of social issues. In one group, unbeknownst to participants, a highly capable adult substituted for peers in half of their dialogs. Beginning immediately, increasing with time, and extending to peer-only dialogs on a new topic, the quality of argumentation shown by the experimental group exceeded that of a comparison peer-only group, highlighting the power of apprenticeship as a mechanism in the development of reasoning, a demonstration of both theoretical and applied significance.

Engagement in purposeful problem solving involving social science content was sufficient to develop a key set of inquiry skills in low-performing middle school students from an academically and economically disadvantaged urban public school population, with this skill transferring to a more traditional written scientific thinking assessment instrument 3weeks later. Students only observing their peers' activity or not participating at all failed to show these gains. Implications are addressed with regard to the mastery of scientific thinking skills among academically disadvantaged students. Also addressed are the efficacy of problem-based learning and the limits of observational learning.

Great effort is invested in identifying ways to change people's minds on an issue. A first priority should perhaps be enriching their thinking about the issue. With a goal of enriching their thinking, we studied the views of community adults on the DACA issue-young adults who entered the United States illegally as children. A dialogic method was employed, offering dual benefits in providing participants the opportunity to further develop their own ideas and to consider differing ideas. Yet, participants engaged in dialog only vicariously by observing the talk of a pair of actors who held opposing positions on DACA. The effect on participants' thinking was greatest in the condition in which they viewed a dialog between the two actors, rather than a comparison condition in which the actors individually expressed their positions. In control conditions, no presentation was observed. Probing questions included in all conditions encouraged a participant to examine and clarify for themselves their own position, potentially enriching it. This condition proved unsuccessful in enriching thinking; participants' justifications for their own positions in fact became simpler and less qualified. In contrast, observing a video of a like-minded and opposing other did enrich observers' thinking, yet to a greater degree in the dialogic than nondialogic condition. The findings thus suggest observed dialog as a promising practical approach in promoting deeper thinking.

Now is an auspicious time to make student-centered discourse a centerpiece of social and civic education, as well as across the curriculum more broadly. We describe here the features of the middle-school program we have developed and implemented for this purpose, emphasizing its concentration on direct student-to-student communication, in contrast to the more common whole-class teacher-led discussion. The Covid-19 epidemic forced us to modify the way in which we implemented the program, eliminating face-to-face contact. What had been an in-person interactive discourse-based workshop we transformed into a remotely-experienced, technology-supported interaction between rotating student pairs. Each participant debated individually with a sequence of individual peers who held an opposing view on a series of social issues. This modified distance-learning approach revealed some unanticipated benefits that we share here. Most notable among them were the enhanced comfort in sharing their views that participants reported they experienced, due to the remote, text-only connection that concealed their personal identities.
RESUMO
Argumentive reasoning skills are featured in the new K-12 Common Standards (Common Core State Standards Initiative, 2010), yet with little said about their nature or how to instill them. Distinguishing reasoning skills from writing skills, we report on a multiyear intervention that used electronically conducted dialogues on social issues as the medium to develop argumentive reasoning skills in two cohorts of young adolescents. Intervention groups demonstrated transfer of the dialogic activity to two individual essays on new topics; argument quality for these groups exceeded that of comparison groups who participated in an intervention involving the more face-valid activity of extensive essay writing practice, along with whole-class discussion. The intervention group also demonstrated greater awareness of the relevance of evidence to argument. The dialogic method thus appears to be a viable one for developing cognitive skills that the comparison-group data show do not routinely develop during this age period.

We present evidence suggesting that the effect of self-explanations on learning is not always beneficial and, in fact, in some contexts has a detrimental effect. Over eight sessions, fourth-graders engaged in investigation of a database with the goal of identifying causal effects. In a separate task, children in one condition also generated self-explanations regarding the mechanisms underlying the causal effects they believed to be present. In a comparison condition, they did not. On a transfer task, children in the no-explanations condition showed superior causal inference performance. The findings are discussed as reflecting the development of "data-reading" skill with which an emphasis on explanations may interfere.

The skill of predicting outcomes based on simultaneous effects of multiple factors was examined. Over five sessions, 91 sixth graders engaged this task either individually or in pairs and either preceded or followed by six sessions on the more widely studied inquiry task that requires designing and interpreting experiments to identify individual effects. Final assessment, while indicating a high level of mastery on the inquiry task, showed progress but continuing conceptual challenges on the multivariable prediction task having to do with understanding of variables, variable levels, and consistency of a variable's operation across occasions. Task order had a significant but limited effect, and social collaboration conferred only a temporary benefit that disappeared in a final individual assessment. In a follow-up study, the lack of effect of social collaboration was confirmed, as was that of feedback on incorrect answers. Although fundamental to science, the concept that variables operate jointly and, under equivalent conditions, consistently across occasions is one that children appear to acquire only gradually and, therefore, one that cannot be assumed to be in place.

We report a study of a class of 28 sixth graders engaged in an extended computer-supported argumentive discourse activity. Participants collaborated with a same-side peer in arguing against successive pairs of peers on the opposing side of an issue. Meta-level awareness was facilitated by conducting the dialogs via instant messaging software, which made available a transcript of the dialog that was used in additional reflective activities. In the course of dialogs on 3 successive topics, participants showed significant gains in meta-level communications about the discourse, reflecting at least implicit understanding of its goals, as well as in the strategic moves that constituted the discourse. The latter advances remained evident when the social support of a same-side partner was withdrawn.

How do inference rules for causal learning themselves change developmentally? A model of the development of causal reasoning must address this question, as well as specify the inference rules. Here, the evidence for developmental changes in processes of causal reasoning is reviewed, with the distinction made between diagnostic causal inference and causal prediction. Also addressed is the paradox of a causal reasoning literature that highlights the competencies of young children and the proneness to error among adults.

RESUMO
The news that the brain continues to develop through much of adolescence risks becoming an explanation for anything and everything about teenagers and suggests the need for closer analysis. Central to such analysis is clarifying what develops at a psychological level during these years. An examination of contemporary research data on adolescent cognitive development identifies increased executive control as a major dimension of cognitive development during the second decade of life. Such development is consistent with changes occurring in the brain during this period.
RESUMO
Academically low-performing urban sixth graders engaged in inquiry activity received a suggestion that they focus their investigation on the role of a single factor. This suggestion had significant effects on their use of a superficially dissimilar strategy--controlling the variation of other factors. This latter strategy has received the lion's share of attention in research on the development of scientific reasoning. These results have implications, we propose, for what undergoes development with respect to scientific thinking and how this development can best be facilitated.

This work sought to obtain experimental evidence to corroborate cross-sectional patterns of development in argument skills and to evaluate the effectiveness of an intervention designed to foster development of these skills in academically at-risk 13- to 14-year-olds. Students participated in 16 sessions of a collaborative, goal-based activity providing dense exercise of argumentive thinking. One condition included peer dialogues; another did not. The former was the more effective, although both groups progressed. Participants showed increased frequency of usage of powerful argumentive discourse strategies, such as counterargument, and decreased frequency of less effective strategies. Quality of individual arguments (for or against a claim) also improved, supporting the existence of a close relation between these two kinds of argument skills.

PURPOSE/OBJECTIVES: To describe the impact of treatment on fertility, discuss fertility-sparing options available for women with breast cancer, and explore pregnancy subsequent to breast cancer. DATA SOURCES: Published research, clinical articles, book chapters, and abstracts. DATA SYNTHESIS: The risk of amenorrhea associated with alkylating agents in breast cancer survivors is well known. Fertility-sparing options before, during, and after treatment are possible with the use of assistive reproductive technology. Young breast cancer survivors are concerned about stimulating recurrence with subsequent pregnancy, health during pregnancy, and family matters. CONCLUSIONS: Current data about the effects of treatment on amenorrhea, subsequent pregnancy after treatment, preservation of ovarian function during adjuvant therapy, and management of ovarian failure in young women with breast cancer are important to include in discussions and counseling. IMPLICATIONS FOR NURSING: Young women deserve a thoughtful discussion about their concerns among their multidisciplinary team, including oncology nurses, oncologists, and social workers. Effects of treatment on fertility are well known. Women with fertility concerns should be referred to a reproductive endocrinology team at the time of diagnosis rather than after treatment has ended.
