There is broad interest to improve the reproducibility of published research. We developed a survey tool to assess the availability of digital research artifacts published alongside peer-reviewed journal articles (e.g. data, models, code, directions for use) and reproducibility of article results. We used the tool to assess 360 of the 1,989 articles published by six hydrology and water resources journals in 2017. Like studies from other fields, we reproduced results for only a small fraction of articles (1.6% of tested articles) using their available artifacts. We estimated, with 95% confidence, that results might be reproduced for only 0.6% to 6.8% of all 1,989 articles. Unlike prior studies, the survey tool identified key bottlenecks to making work more reproducible. Bottlenecks include: only some digital artifacts available (44% of articles), no directions (89%), or all artifacts available but results not reproducible (5%). The tool (or extensions) can help authors, journals, funders, and institutions to self-assess manuscripts, provide feedback to improve reproducibility, and recognize and reward reproducible articles as examples for others.

This activity introduces students to an actual data set that explores the impacts of ocean acidification on tropical coral reef ecosystems. Students are first given a scenario for a field site in the Caribbean and are asked to design an experiment that answers the question: How will a decline in surface ocean pH by the 21st century impact tropical coral growth? Students then gather actual data (from coral images collected from the field site) to calculate calcification rates of different coral samples. Finally, students use the provided saturation state values to predict the extent to which coral calcification is expected to decline by the 21st century.

Finding themselves in the middle of the Amazon rainforest after a plane crash, students use map scales, keys, and longitude and latitude coordinates to figure out where they are. Then they work in groups to generate ideas and make plans. They decide where they should go to be rescued, the distance to that location, the route to take, and make calculations to estimate walking travel time.

"Research is increasingly showing the impact of the microbiome -- the diverse microbial communities living within the gut -- on human health. But, _when_ and _how_ is the microbiome established? Two opposing hypotheses have been put forward. For over a century, the prevailing thought has been that the human fetal environment is sterile and that microbes are acquired during and after birth. If this view is correct, the microbiome of infants born via C-section should differ from those born vaginally. Recent studies using molecular techniques, however, suggest that bacterial communities may be present in the placenta, amniotic fluid, and the baby’s first stool. They posit that the acquisition of the gut microbiome, therefore, begins _in utero_. If this is the case, delivery method should have less of an effect on early microbiome assembly..."

The Assessment of Authentic Learning Rubric focuses on the areas of agency and authenticity, concepts derived from the Student as Producer and Social Pedagogies frameworks. The rubric consists of five areas: learning tasks, learning process, social core, learning assessments, and lifelong learning. Each of the five areas contains statements that course designers can use to evaluate their course/s. Instructors may elect to use the rubric as a self-evaluation tool or might elect to work through it with support from an instructional designer. The rubric can be used for course taught in a variety of modalities including online, hybrid, and face-to-face.

This 7-week lesson plan is designed for use in clinical nursing courses. It is designed specifically for use by Nursing faculty teaching in the absence of state required patient facing clinical opportunity due to COVID restrictions. The lesson plan describes pedagogical techniques and provides video and education OER resources designed to help support the development of empathetic communication skills over 7 weeks. Refection and video debriefing techniques will be employed. Role play will culminate in the group presentation project of a brief video modeling effective therapeutic empathetic communication.

"Consuming high amounts of red meat is commonly linked to an increased risk of developing cancer, especially colorectal cancer. At the same time, antibodies against Neu5Gc , a carbohydrate derived from red meat, have been observed to worsen cancer in “human-like” mice. While these antibodies and red meat consumption are each believed to increase cancer risk, it remains unknown how diet affects the antibodies. Now, research suggests that consuming Neu5Gc from red meat and dairy can modulate the amounts and properties of anti-Neu5Gc antibodies in humans, providing clues to how the carbohydrate might be linked to cancer. The team behind the study calculated daily intake of Neu5Gc for more than 19,000 subjects aged 18 years or older. These participants provided regular logs of food consumed over 24-hour periods as part of the NutriNet-Santé study, which was designed to investigate relationships between nutrition and health status..."

To increase transparency in research, the International Committee of Medical Journal Editors required, in 2005, prospective registration of clinical trials as a condition to publication. However, many trials remain unregistered or retrospectively registered. We aimed to assess the association between trial prospective registration and treatment effect estimates. Methods This is a meta-epidemiological study based on all Cochrane reviews published between March 2011 and September 2014 with meta-analyses of a binary outcome including three or more randomised controlled trials published after 2006. We extracted trial general characteristics and results from the Cochrane reviews. For each trial, we searched for registration in the report’s full text, contacted the corresponding author if not reported and searched ClinicalTrials.gov and the International Clinical Trials Registry Platform in case of no response. We classified each trial as prospectively registered (i.e. registered before the start date); retrospectively registered, distinguishing trials registered before and after the primary completion date; and not registered. Treatment effect estimates of prospectively registered and other trials were compared by the ratio of odds ratio (ROR) (ROR <1 indicates larger effects in trials not prospectively registered). Results We identified 67 meta-analyses (322 trials). Overall, 225/322 trials (70 %) were registered, 74 (33 %) prospectively and 142 (63 %) retrospectively; 88 were registered before the primary completion date and 54 after. Unregistered or retrospectively registered trials tended to show larger treatment effect estimates than prospectively registered trials (combined ROR = 0.81, 95 % CI 0.65–1.02, based on 32 contributing meta-analyses). Trials unregistered or registered after the primary completion date tended to show larger treatment effect estimates than those registered before this date (combined ROR = 0.84, 95 % CI 0.71–1.01, based on 43 contributing meta-analyses). Conclusions Lack of trial prospective registration may be associated with larger treatment effect estimates.

Through this earth science curricular unit, student teams are presented with the scenario that an asteroid will impact the Earth. In response, their challenge is to design the location and size of underground caverns to shelter the people from an uninhabitable Earth for one year. Driven by this adventure scenario, student teams 1) explore general and geological maps of their fictional state called Alabraska, 2) determine the area of their classroom to help determine the necessary cavern size, 3) learn about map scales, 4) test rocks, 5) identify important and not-so-important rock properties for underground caverns, and 6) choose a final location and size.

In this lesson, students learn some basic facts about asteroids in our solar system. The main focus is on the size of asteroids and how that relates to the potential danger of an asteroid colliding with the Earth. Students are briefly introduced to the destruction that would ensue should a large asteroid hit, as it did 65 million years ago.
