Intervention studies with developmental samples are difficult to implement, in particular when targeting demographically diverse communities. Online studies have the potential to examine the efficacy of highly scalable interventions aimed at enhancing development, and to address some of the barriers faced by underrepresented communities for participating in developmental research. During the COVID-19 pandemic, we executed a fully remote randomized controlled trial (RCT) language intervention with third and fourth-grade students (N = 255; age range 8.19-10.72 years, mean = 9.41, SD = 0.52) from diverse backgrounds across the United States. Using this as a case study, we discuss both challenges and solutions to conducting an intensive online intervention through the various phases of the study, including recruitment, data collection, and fidelity of intervention implementation. We provide comprehensive suggestions and takeaways and conclude by summarizing some important tradeoffs for researchers interested in carrying out such studies.

Background/Context Billions of dollars are spent annually on professional development (PD) for educators, yet few randomized controlled trials (RCT) have demonstrated the ultimate impact PD has on student learning. Further, while policymakers and others speak to the role schools should play in developing students’ civic awareness, RCTs of PD designed to foster civic learning are rare. This randomized controlled trial contributes to the knowledge base on the effectiveness of PD designed to integrate civic learning, ethical reflection, and historical thinking skills into high school humanities courses. Focus of Study The study examined the impact of a PD intervention in two areas: (a) teacher self-efficacy, burnout, and professional engagement and satisfaction; and (b) the academic, civic, social, and ethical competencies of 9th and 10th grade students in the teachers’ classes. Population/Participants/Subjects The study involved 113 teachers and 1,371 9th and 10th grade students in 60 high schools from eight metropolitan regions in the United States. Intervention/Program/Practice The intervention, Facing History and Ourselves, provides PD through a five-day seminar, curricular materials, and follow-up coaching and workshops to help teachers develop their capacities to implement an interdisciplinary historical case study unit using student-centered pedagogy. Research Design The study used a school-level, randomized, experimental design to investigate impacts of the intervention for teachers and their 9th and 10th grade students. Findings/Results Intervention teachers showed significantly greater self-efficacy in all eight assessed domains, more positive perceptions of professional support, satisfaction and growth, and greater personal accomplishment. Intervention students demonstrated stronger skills for analyzing evidence, agency, and cause and effect on a historical understanding performance measure; greater self-reported civic efficacy and tolerance for others with different views; and more positive perceptions of the classroom climate and the opportunities afforded for engaging with civic matters. Fidelity analysis found these causal effects despite the fact that roughly half of the intervention teachers did not fully implement the program. Conclusions/Recommendations Educators need evidence-based approaches for teaching complex social, civic, and political issues enabling students of diverse mindsets and backgrounds to engage constructively with one another while obtaining necessary skills and knowledge. These findings provide empirical support for a professional development approach that engages teachers in fostering academic and civic competencies critical to both participation in a democracy and success in college and career.

Objective: To provide guidance to criminologists for conducting experiments in light of two common discouraging factors: the belief that they are overly time-consuming and the belief that they can compromise the ethical principles of human subjects’ research. Method: A case study approach is used, based on a large-scale randomized controlled trial experiment in which we exposed participants to a 5-s TASER shock, to describe how the authors overcame ethical, methodological, and logistical difficulties. Results: We derive four pieces of advice from our experiences carrying out this experimental trial: (1) know your limitations, (2) employ pilot testing, (3) remain flexible and patient, and (4) “hold the line” to maintain the integrity of the research and the safety of human subjects. Conclusions: Criminologists have an obligation to provide the best possible evidence regarding the impact and consequences of criminal justice practices and programs. Experiments, considered by many to be the gold standard of empirical research methodologies, should be used whenever possible in order to fulfill this obligation.

An understanding of fractions eludes many U.S. students, and research-based knowledge about fractions, such as the utility of linear representation, has not broadly influenced instruction. This randomized trial of lesson study supported by mathematical resources assigned 39 educator teams across the United States to locally managed lesson study supported by a fractions lesson study resource kit or to 1 of 2 control conditions. Educators (87% of whom were elementary teachers) self-managed learning over a 3-month period. HLM analyses indicated significantly greater improvement of educators' and students' fractions knowledge for teams randomly assigned to lesson study with resource kits. Results suggest that integrating researchbased resources into lesson study offers a new approach to the problem of “scale-up” by combining the strengths of teacher leadership and research-based knowledge.

Every day, acts of violence injure more than 6000 people in the United States. Despite decades of social science arguing that joblessness among disadvantaged youth is a key cause of violent offending, programs to remedy youth unemployment do not consistently reduce delinquency. This study tests whether summer jobs, which shift focus from remediation to prevention, can reduce crime. In a randomized controlled trial among 1634 disadvantaged high school youth in Chicago, assignment to a summer jobs program decreases violence by 43% over 16 months (3.95 fewer violent-crime arrests per 100 youth). The decline occurs largely after the 8-week intervention ends. The results suggest the promise of using low-cost, well-targeted programs to generate meaningful behavioral change, even with a problem as complex as youth violence.

Vaccination rates have stagnated in the United States and the United Kingdom leading to the continuing spread of COVID-19. Fear and concern over vaccine side-effects is one of the main drivers of hesitancy. Drawing from behavioral science and health communication theory, we conducted a randomized controlled trial among 8998 adults to determine whether the way COVID-19 vaccine side-effects are framed and presented to individuals can influence their willingness to take a vaccine. We presented participants information on a hypothetical future COVID-19 vaccine -- including information on its side-effect rate -- and then examined the effect of three side-effect framing strategies on individuals stated willingness to take this vaccine: adding a qualitative risk label next to the numerical risk, adding comparison risks, and for those presented with comparisons, framing the comparison in relative rather than absolute terms. Based on a pre-registered and published analysis plan, we found that adding a simple descriptive risk label (very low risk) next to the numerical side-effect increased participants' willingness to take the COVID-19 vaccine by 3.0 percentage points (p = 0.003). Providing a comparison to motor vehicle mortality increased COVID-19 vaccine willingness by 2.4 percentage points (p = 0.051). These effects were independent and additive: participants that received both a qualitative risk label and comparison to motor-vehicle mortality were 6.1 percentage points (p < 0.001) more likely to report willingness to take a vaccine compared to those who did not receive a label or comparison. Taken together, our results reveal that despite increasingly strong vaccination hesitancy and exposure to large amounts of vaccine misinformation, low-cost side-effect framing strategies can meaningfully affect vaccination intentions at a population level.
