Clearinghouse for Training Modules to Enhance Data Reproducibility

​The external links from this webpage provide additional information that is consistent with the intended purpose of this site. NIGMS cannot attest to the accuracy or accessi​bility of a nonfederal site.

In January 2014, NIH launched a series of initiatives to enhance rigor and reproducibility in research. As a part of this initiative, NIGMS, along with nine other NIH institutes and centers, issued a funding opportunity announcement (FOA) RFA-GM-15-006 to develop, pilot, and disseminate training modules to enhance data reproducibility. This FOA was reissued in 2018 (RFA-GM-18-002).

For the benefit of the scientific community, we will post the products of grants funded by these FOAs on this website as they become available. In addition, we are sharing here other relevant training modules developed, including courses developed from administrative supplements to NIGMS predoctoral T32 grants.

NIH Rigor and Reproducibility Training Modules

These modules, developed by NIH, focus on integral aspects of rigor and reproducibility in the research endeavor, such as bias, blinding, and exclusion criteria. The modules are not meant to be comprehensive, but rather are intended as a foundation to build on and a way to stimulate conversations, which may be facilitated by the accompanying discussion materials. Currently, the modules are being integrated into NIH training activities.

Let's Experiment: A Guide for Scientists Working at the Bench
iBiology, R25 GM116704

"Let's Experiment" is a FREE 6-week online course designed for students and practitioners of experimental biology. Scientists from a variety of backgrounds give concrete steps and advice to help you build a framework for how to design experiments. We use case studies to make the abstract more tangible. In science, there is often no simple right answer. However, you can develop a general approach to experimental design and understand what you are getting into before you begin.

By the end of this course, you will have:

  • A detailed plan for your experiment(s) that you can discuss with a mentor.
  • A flowchart for how to prioritize experiments.
  • A lab notebook template that is so impressively organized, it will make your colleagues envious.
  • A framework for doing rigorous research.

Improving Reproducibility in Research
Aaron Carroll, Indiana University School of Medicine, R25 GM116146

In order to promote better training and ensure the reliability and reproducibility of research, we developed a series of webisodes (thematically related online videos) targeted at graduate students, postdoctoral fellows, and beginning investigators that addresses critical features of experimental design and analysis/reporting.

Module 1: Experimental Design Learning Module

The Experimental Design Learning Module focuses on the intricacies of designing research that is robust, with an eye toward making it reproducible. It is comprised of four distinct learning units:

  1. Replication,
  2. Randomization,
  3. Pitfalls with Experimental Design, and
  4. Measurement.

Each of these learning units has one or more sub-topics that is the subject of an individual webisode.

Module 2: Analysis/Reporting Learning Module

The Analysis/Reporting Learning Module covers the various factors that are critical to writing about research with enough clarity to ensure its reproducibility. Very few researchers are given formal education on how to properly report findings to support reproducibility. It is comprised of three distinct learning units:

  1. Power and P-values,
  2. Scientific Writing, and
  3. The Review Process.

Each of these learning units has one or more sub-topics that is the subject of an individual webisode.

This teaching module was designed to help biomedical researchers understand the changing standards of practice for studies using animals as research models. This module is comprised of three sections that focus on developing strong skills in designing animal studies, analyzing results from those studies, and reporting findings that are reproducible. Modules are designed to be used by higher education institutions, laboratory groups, individuals, and professional societies.

Lesson 1: Experimental Design
The Experimental Design lesson focuses on the experimental details needed to support the design and implementation of a well-controlled animal study.

Lesson 2: Analyzing Results
The Analyzing Results lesson focuses on how to assess datasets on which article figures are based and consider whether the information in the dataset is sufficient for creating an interpretable figure.

Lesson 3: Reporting Results
The Reporting Results lesson focuses on the details of an animal experiment to be reported in a manuscript.

A series of 14 tutorials on improving the reproducibility of data analysis for those doing microbial ecology research. Although the materials focus on issues in microbiome research, the principles are broadly applicable to other areas of microbiology and science. This series of lessons focus on the importance of command line practices (e.g. bash), scripting languages (e.g. mothur, R), version control (e.g. git), automation (e.g. make), and literate programming (e.g. markdown). These are the tools that are used by a growing number of microbiome researchers to help improve the reproducibility of their research. By completing the activities in the tutorials, you will be listed on the Reproducible Research Tutorial Honor Roll, which provides a certification of your training.

Cell Line Authentication Training
Leonard Freedman, Global Biological Standards Institute® (GBSI), R25 GM116155

GBSI and its partners developed an exportable "active learning" training module to reduce cell line misidentification, mislabeling, and contamination. This module contains highly interactive training units, including "back to the lab" exercises that will turn learning into practice by sending the trainees back into the laboratory to practice their skills. The importance of cell line authentication when using cultured lines will improve the credibility, reproducibility, and translation of preclinical research.
