About the Database

Direct Instruction (DI) programs are based on over 40 years of research on how children learn and the most effective ways to teach. Studies involving DI curricula and its implementation have been conducted with a wide variety of populations, in different settings and within all subject areas related to the programs. As such, the volume of research on DI is expansive. The National Institute for Direct Instruction (NIFDI) makes this extensive research base more accessible to educators and researchers through a free online database of over 200 entries.

Until now, users’ ability to search has been limited to keyword, author, research area and year. Now, users have the ability to search by the type of content the entry covers, organized into the following categories:

  1. DI Overview and Background – Textbooks about DI, general books regarding the program, the history of its development, etc.

  2. Program Effectiveness – Documentation proving DI’s effectiveness.

  3. DI Theory – The theoretical and experimental work that provided the foundation for the development of the programs.

  4. Implementation Support – Content with instructions for teachers, studies of implementation fidelity, school reform, administrative issues, etc.

  5. DI Curricula – A listing of the programs that have been developed.

As a result of these changes, users can now funnel their queries down to very specific parameters. For example, a user can search for articles that evaluate the effectiveness of DI reading programs for elementary aged students and then sort by the year the articles were published to include ones within a specified time span, such as the last five years.

Options for searching the database, including the selection option for the new content categories, are found at the top of the page. Simply enter your desired parameters and click “go”. The NIFDI Office of Research and Evaluation is continually evaluating and adding content relevant to DI. As a result, the DI Research Database is a dynamic tool that will regularly expand and evolve with entries and categories added on an on-going basis.
