Impact of the School Environment on Medical Treatment of Attention Deficit Hyperactivity Disorder: A Population-Wide Register Data Study of School-Wide Positive Behavioral Interventions and Supports

Although attention deficit hyperactivity disorder (ADHD) is among the most heritable psychiatric childhood disorders, social and gene–environment interactions seemingly play an important role in the etiology of ADHD. Consistent with this, this study finds that School-Wide Positive Behavioral Interventions and Supports (SWPBIS) reduced the likelihood of pharmacotherapeutic treatment for ADHD at age 14–16 by 12%, using population-wide Norwegian register data and a difference-in-difference design (N = 698,364, birth cohorts 1990–2002, 48.7% girls, 5.7% immigrant background). At-risk students in schools with high fidelity of implementation are driving these intervention effects. Overall, the findings indicate that children with a genetic disposition for ADHD are more likely to avoid medical treatment in an organized and predictable school setting with a focus on positive reinforcement.     

Comparing university organizations across boundaries

The article discusses comparative organizational studies, focusing on change in higher education institutions, and in particular (but not only) on studies that compare organizations in different national settings. It first presents and discusses different approaches to comparison based on a couple of typologies that have been developed to identify different research strategies (cf. Page in Public Adm 73(1):123–141, 1995; Skocpol in Vision and method in historical sociology. Cambridge, Cambridge University Press, 1980: 356–391). It focuses on comparative strategies, and distinguishes between different strategies based on how issues of causality and generalizability are addressed. It illustrates how strategies may be used and combined with examples from comparative research projects, in many of which the author has participated. The second part deals with the current status of comparative research in higher education, and argues that a move in the direction of more rigorous, systematic comparisons is not just a question of quantification, but of conceptualization, and in particular that there is a need for concepts that can travel in meaningful ways. The experiences of one large comparative project, TRUE, are drawn upon in order to demonstrate how some of the challenges mentioned above, may be dealt with.     

Trust and mistrust when students read multiple information sources about climate change

The present study investigated how undergraduates judged the trustworthiness of different information sources that they read about climate change. Results showed that participants (N = 128) judged information from textbook and official documents to be more trustworthy than information from newspapers and a commercial agent. Moreover, participants put most emphasis on content and least emphasis on date of publication when judging document trustworthiness. When judging the trustworthiness of the textbook, they emphasized criteria differently than when evaluating other types of documents. Results also indicated that readers low in topic knowledge were more likely to trust less trustworthy sources and failed to differentiate between relevant and irrelevant criteria when judging the trustworthiness of sources.     

Blinded by the Light: How a Focus on Statistical “Significance” May Cause p-Value Misreporting and an Excess of p-Values Just Below .05 in Communication Science

Publication bias promotes papers providing “significant” findings, thus incentivizing researchers to produce such findings. Prior studies suggested that researchers’ focus on “p < .05” yields—intentional or unintentional—p-value misreporting, and excess p-values just below .05. To assess whether similar distortions occur in communication science, we extracted 5,834 test statistics from 693 recent communication science ISI papers, and assessed prevalence of p-values (1) misreported, and (2) just below .05. Results show 8.8% of p-values were misreported (74.5% too low). 1.3% of p-values were critically misreported, stating p < .05 while in fact p > .05 (88.3%) or vice versa (11.7%). Analyzing p-value frequencies just below .05 using a novel method did not unequivocally demonstrate “p-hacking”—excess p-values could be alternatively explained by (severe) publication bias. Results for 19,830 p-values from social psychology were strikingly similar. We conclude that publication bias, publication pressure, and verification bias distort the communication science knowledge base, and suggest solutions to this problem.     

Task-oriented reading of multiple documents: online comprehension processes and offline products

We explored readers’ judgments of text relevance and strategy use while they read about a controversial scientific issue in multiple conflicting documents using a think-aloud methodology and had them write a short essay after reading. Participants were university-level students. There were three main findings. First, readers discriminated between more- and less-relevant information while they read. Second, the frequency with which they used strategies differed while they read more- and less-relevant information. Specifically, while they read more-relevant information, students were more likely to build connections between that information and information in other texts. Third, their judgments of more-relevant segments as relevant and their evaluation of less-relevant information while they read were related to the quality of students’ essays after they read. We discuss how the findings may contribute to the literature on task-oriented reading of multiple documents.     

Job Values in Professional Education: The role of achievement goals

What kind of jobs students prefer after having completed their professional education may have important personal and organisational consequences. It is therefore essential to gain a better understanding of the job values they pursue, as well as of the antecedents of such values. In this longitudinal study, we first showed that the job values of the 152 participating Norwegian student nurses and student teachers could be divided into extrinsic job values, such as high salary and good opportunities for advancement, and intrinsic job values, such as good social relations and interesting work. Moreover, we found that an important aspect of academic motivation, that is, students' achievement goals, predicted their job values. Specifically, students adopting performance‐approach goals were more likely to pursue extrinsic job values and students adopting mastery goals were more likely to pursue intrinsic job values. Ways in which the findings address current controversies in the literature on achievement goals are discussed.     

Vygotsky as Precursor to Metacognitive Theory: II. Vygotsky as Metacognitivist

In this article it is demonstrated that topics discussed in contemporary metacognitive research are integral parts of Vygotsky's (1978, 1986) theory of cognitive development. This conclusion is reached through a discussion of Vygotsky's views of self‐regulation, the relationship between self‐awareness and self‐regulation, and the relationship between awareness/regulation on the one hand and cognitive process on the other. The uniqueness of a Vygotskian approach to metacognition is also specified. This uniqueness resides in Vygotsky's focus on the sign system of human language, on the linguistic tools of thought and the central role they play in mediating cognitive performance.     

Teachers' source evaluation self‐efficacy predicts their use of relevant source features when evaluating the trustworthiness of web sources on special education

Building on prior research and theory concerning source evaluation and the role of self‐efficacy in the context of online learning, this study investigated the relationship between teachers' beliefs about their capability to evaluate the trustworthiness of sources and their reliance on relevant source features when judging the trustworthiness of websites concerning special education. We constructed the Source Evaluation Self‐Efficacy Scale (SESES) and used the scores of 263 teachers on this measure to predict their reliance on source features related to the product and the producer of websites when evaluating their trustworthiness. Results showed that even after variance related to gender, age, domain knowledge and frequency of searching the Internet for special education information had been accounted for, teachers' source evaluation self‐efficacy beliefs uniquely predicted their self‐reported use of information about websites' products and producers when judging their trustworthiness. Thus, this research applies self‐efficacy theory and research to a new area and contributes to the burgeoning literature on source evaluation within both reading and information literacy.
