How Do Sibling Conflicts End?

The endings of sibling conflicts were investigated in 40 families at 2 time periods. Each family included 2 children, studied when they were 2 1/2 and 4 1/2 years of age, and 2 years later, at 4 1/2and 6 1/2 years. Four types of conflict endings were observed in sibling conflicts: Compromise, Reconciliation, Submission, and No Resolution. Results indicate that at both time periods conflicts typically ended with No Resolution, followed by Submission, Compromise, and finally, Reconciliation. Submissions decreased and No Resolutions increased over the two time periods; no changes were observed in either Compromise or Reconciliation. Parents' interventions led directly to a resolution of 16% of the children's disputes (Parent Ending). In those cases, there was a greater likelihood of conflicts ending in Compromise or Reconciliation than when parents did not intervene. Conflicts in which parents intervened but the children ultimately resolved the conflicts themselves (Child Ending with Intervention) occurred 42% of the time. Such conflicts ended more often with No Resolution and less often with children's Submissions to their siblings. The implications of these findings for the development of children's conflict resolution skills and the role of parent involvement are discussed.

Intention to Transfer: How Do Autonomous Professionals Become Motivated to Use New Ideas?

Although performance technologists recognize the importance of transfer, there are few studies of this complex process from the perspective of the individual, autonomous professional. For these trainees, intention to apply an idea is a vital part of transfer. Thus we asked: How do autonomous professionals learning from a training program form their intentions to apply? Over eight years we collected and analyzed 180 stories of application from 73 physicians attending a faculty development fellowship. In the majority of stories, Fellows said they formed their intentions to transfer during training sessions. Of those Fellows, most said they formed intentions toward a general target while listening to explanations. To form their intentions, Fellows weighed their experiences in training against job requirements, task experiences, self‐evaluations, and goals and values. As Fellows decided to use an idea, they considered its credibility, practicality and need. Based on our analyses of the stories, we present a model for the intention to transfer and discuss its implications for practice and research.     

Do Friendships Afford Academic Benefits? A Meta-analytic Study

Using meta-analytic techniques, we examined systematically the evidence linking friendship to academically related outcomes, asking: To what extent is friendship related to academic performance and to academically related cognitive skills? Based on 22 studies that yielded 81 effect sizes and 28 independent samples, we examined relations between friendship and academically related cognitive skills (e.g., scientific reasoning, linguistic skills, spatial memory) and performance (e.g., academic grades, test scores). The role of friendship was defined in one of two ways: working with mutual friends on academic tasks and the experience of having friendships (as indicated by having at least one reciprocated friend or a number of friends). Small to moderate effect sizes suggest that working together with a friend and simply having a friend were related significantly and positively both to cognitive and performance outcomes. Student (sex, age, country of origin) and methodological (measurement, design) characteristics were not significant moderators of relations between friendship and academically related outcomes.     

Why Do Achievement Measures Underpredict Female Academic Performance?

In the context of college admissions, the current study examined whether differential prediction of first‐year grade point average (FYGPA) by gender could be explained by an omitted variable problem—namely, academic discipline, or the amount of effort a student puts into schoolwork and the degree to which a student sees him/herself as hardworking and conscientious. Based on nearly 10,000 college students, the current study found that differences in intercepts by gender were reduced by 45% with the inclusion of academic discipline in a model that already included high school grade point average (HSGPA) and ACT Composite score. Moreover, academic discipline resulted in an additional 4% of variance accounted for in FYGPA. Gender differences in slopes were not statistically significant (p > .001) regardless if academic discipline was included in the model. The findings highlight the utility of taking a more holistic approach when making college admission decisions. Namely, the inclusion of noncognitive measures has benefits that are twofold: increased predictive validity and reduced differential prediction.     

Model-Based Teaching and Learning with BioLogica™: What Do They Learn? How Do They Learn? How Do We Know?

This paper describes part of a project called Modeling Across the Curriculum which is a large-scale research study in 15 schools across the United States. The specific data presented and discussed here in this paper is based on BioLogica, a hypermodel, interactive environment for learning genetics, which was implemented in multiple classes in eight high schools. BioLogica activities, data logging, and assessments were refined across this series of implementations. All students took a genetics content knowledge pre- and posttests. Traces of students' actions and responses to computer-based tasks were electronically collected (via a log file function) and systematically analyzed. An intensive 3-day field test involving 24 middle school students served to refine methods and create narrative profiles of students' learning experiences, outcomes, and interactions with BioLogica. We report on one high school implementation and the field test as self-contained studies to document the changes and the outcomes at different phases of development. A discussion of design changes concludes this paper.

How Do Academic Achievement and Gender Affect the Earnings of STEM Majors? A Propensity Score Matching Approach

The United States government recently enacted a number of policies designed to increase the number of American born students graduating with degrees in science, technology, engineering and mathematics (STEM), especially among women and racial and ethnic minorities. This study examines how the earnings benefits of choosing a STEM major vary both by gender and across the distribution of academic achievement. I account for the selection into college major using propensity score matching. Measures of individual educational preferences based on Holland’s theory of career and educational choice provide a unique way to control for college major selection. Findings indicate that the earnings benefit to STEM major choice ranges from 5 to 28 % depending both on academic achievement and on gender and that high-achieving students benefit more from STEM major choice. Further, high achieving men benefit more from STEM majors than high-achieving women. Earnings differences in major choice may play an important role in explaining the underrepresentation of women in STEM major fields, especially among high achieving students.

How Do the Movies Do It?（高一适用）

Have you ever seen a movie in which a building was burned down or a bridge was destroyed? Have you seen films in which a train crashed or a ship sank into the ocean? If so, you may have wondered how these things could happen without harming the people in the film.The man who knows the answer is the special-effects man. He has one of the most important jobs in the film industry. He may be ordered to create a flood or to make a battlefield explode. And he may also be asked to create a special effect which is much less exciting, though just as important to the sue-
