Language and Literacy Strategies for Indigenous Children: A Scoping Review

Abstract

The purpose of this scoping review was to describe the existent research on language and literacy strategies for Indigenous children and to establish the strength of strategies described. A scoping review was conducted to locate existent studies that described language and literacy interventions used with Indigenous children. The following electronic databases were searched: PsycINFO, ERIC, CINAHL Complete, Academic Search Premier, Education Source, and ASHAWire. Articles were managed and analyzed using Covidence, a web-based program for review research. Results were charted and a preliminary evidence map was created. Forty sources were identified that described language and literacy strategies for Indigenous children. Strength of strategy coding revealed 5 sources had compelling strength, 5 had promising strength, and 30 had lacking strength. Overall, there remains limited research describing language and literacy strategies for Indigenous children. A preliminary evidence map was created to chart each strategy and sources that included the strategy, and to indicate the highest strategy strength observed across sources. A discussion of compelling strategies as well as strategies that may be culturally responsive is provided.

INDIGENOUS POPULATIONS

The terms Indigenous and Native American are terms used to describe tribal communities in the United States, First Nations in Canada, and other Indigenous communities in Central America as defined by the National Congress of American Indians.[1] However, the U.S. government often reports population data using the terms American Indian or Alaskan Native. For example, the National Center on Educational Statistics defines American Indian or Alaska Native as a person having origins in any of the original peoples of North and South America (including Central America) and maintaining tribal affiliation or community attachment.[2] For consistency, the term Indigenous will be used throughout this article.

The overall population of Indigenous people is increasing; there are approximately 574 federally recognized tribes in the United States.[1] In 2020, Indigenous people accounted for 1.1% (3.7 million) of all people living in the United States, compared with 0.9% (2.9 million) in 2010. Together, individuals who identified as Indigenous or Indigenous in combination with another race comprised 9.7 million people (2.9% of the total population) in 2020, up from 5.2 million (1.7%) in 2010. Several states including Alaska, South Dakota, New Mexico, and Oklahoma have more than 10% of the state population consisting of individuals who identify as Indigenous.

NEED FOR LANGUAGE AND LITERACY RESEARCH WITH INDIGENOUS CHILDREN

Indigenous children experience profound educational disparities including decreased access to educational opportunity, lower graduation rates, higher rates of suspension/expulsion, and the highest drop-out rate compared with other races and ethnicities.[2] In addition, the most recent data reporting the representation of Indigenous children in special education has shown disproportionate representation across disability categories. Nationwide, Indigenous students continue to be the racial/ethnic group with the highest percentage of students served in special education, with 18% enrolled in special education.[3] Of Indigenous children in special education, 38% were identified with specific learning disabilities, 16% with speech-language impairment, and 12% had other health impairment.[2] Furthermore, a higher percentage of Indigenous students (10%) received services for developmental delay, compared with 6% of all students. Indigenous students were less likely to receive services for autism (6%) and were underrepresented as gifted and talented.

Researchers have attributed these educational disparities to the systematic failure of school systems to tap into the strengths of Indigenous children and communities.[4] [5] The authors of this scoping review have proposed that a culturally responsive way to address the language and literacy needs of Indigenous children is to shift from a deficit model to an abundance model.[6] A deficit model focuses on child weaknesses; what a child cannot do; and attributes poor performance to personal, family, and/or cultural characteristics. An abundance model has a relational and intergenerational focus that emphasizes support, empowerment, and opportunities with the aim of developing a child's cultural assets.[6] [7] An abundance model focuses on the child's positive development, identifying and building up student and family assets, and the discussion is centered on the child's interest, strengths, skills, talents, and competencies. The abundance model can lead to greater understanding when working with Indigenous families and students.

Adequately meeting the developmental and educational needs of Indigenous children requires that researchers and educational teams learn about existent language and literacy strategies that have been used to address the learning needs of this population. In the spirit of an abundance model and identifying existing strengths, a scoping review of the existent research literature will provide a summary of what is understood about language and literacy interventions with Indigenous children. It essentially will inform what works and what can be improved.

PURPOSE AND APPROACH

The current study will summarize what is known about language and literacy strategies for Indigenous children. The purpose of this study is to (1) identify and describe the existent research on language and literacy strategies with Indigenous children; (2) classify the strength of strategies from this literature.

The authors applied a scoping review methodology to search, review, and classify the strength of language and literacy strategies for Indigenous children. The goals of a scoping review include examining the depth and quality of research on a given topic; summarizing and mapping research findings for practitioners or consumers; and identifying gaps in the research to establish areas for future research. Scoping reviews employ an iterative and flexible process in which potential sources are collected, examined for their relevance to the research question, and mapped according to how they relate to the key concepts underpinning the research question. There are five stages to a scoping review[8]:

1. Identifying the research question.

2. Identifying relevant studies.

3. Selecting studies.

4. Charting the data.

5. Collating, summarizing, and reporting the results.

METHODS

Search Strategy

The authors followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review (PRISMA-ScR) guidelines for this study.[9] The PRISMA-ScR protocol provides authors with guidelines for documenting and reporting scoping review details including 22 reporting points from abstract to conclusions. The PRISMA-ScR protocol completed for this scoping review is available as a supplementary appendix ([Supplementary Material]). This protocol was used to guide decision making and documentation. Covidence review software was used to manage the charting of the data.[10] Covidence is a web-based software platform that facilitates importing sources from databases, citation screening, full-text review, data selection, data charting, and data extraction.

Procedure

Stage 1: Identifying the Research Question: Objectives of the Scoping Review

This scoping review examined research with Indigenous children birth to 18 years of age to answer the following two questions.

1. What language and literacy strategies are described in the research literature?

2. What is the strength of strategies identified?

Stage 2: Identifying Relevant Studies

The authors developed the search terms based on the research questions and their experience and knowledge of Indigenous populations and language and literacy. [Table 1] provides the search terms across four columns. All combinations of terms were searched in each database, but combinations of search terms within term groups were not used. Instead, each search string consisted of one term from each term group joined by “AND.” The research team conducted a search of EBSCO electronic databases including PsycINFO, ERIC, CINAHL Complete, Academic Search Premier, and Education Source (completed October 2021). To check reliability of database searches, approximately 10% of the search terms combination database queries were replicated, where a member of the research term repeated a search term combination in a database to check to see if the same sources appeared as were obtained in the initial search. A 100% reliability rate was obtained for these reliability checks. Next, the ASHAWire search engine was used to locate additional sources. ASHAWire is a search tool that provides a fully interconnected network of publications from the American Speech-Language-Hearing Association (completed October 2021). Finally, in line with typical scoping review procedures, a hand search of promising sources, including reference lists and known sources, was completed (completed November 2021).

Each search string consisted of one term from each term group joined by “AND.”

Stage 3: Selecting Studies

The selection of studies involved two steps: initial title and abstract screening and full-text review. Initial title and abstract screening was conducted to establish if sources were relevant based on the inclusion criteria below.

1. The study or intended population must be Native American or Indigenous as defined by the National Congress of American Indians.[1]

2. Participants must be children or teachers/caregivers (agents) who deliver the intervention to children.

3. The intervention program must be intended for language and/or literacy.

Title and abstract screening. Each study identified underwent initial title and abstract screening by the first or second author and a graduate student who had been trained in the screening criteria. After initial training and review of terms and software features, the first 10 articles were screened by two coders to establish screening consistency. Each study was screened to ensure it met the inclusionary criteria. Then, coders completed title and abstract screening using Covidence software, with two coders (one of the authors and a graduate student in speech-language pathology) coding each of the sources. Agreements and disagreements across coders were tracked by Covidence. Agreements immediately were advanced to full-text review or were removed based on screening decisions. Disagreements were flagged by Covidence for resolution coding, in which the coder who had not previously been involved in screening of the source screened the article and discussed the final decision with the team during weekly meetings.

Full-text review. Sources that had been advanced to full-text review were reviewed by at least one of the authors and a graduate student. Each study was again reviewed to ensure the study met the inclusionary criteria. The criteria were reviewed during a team meeting and Covidence features and procedures were reviewed prior to beginning full-text reviews. Covidence features included recording the reason an article was excluded during this stage and having coders take relevant notes within Covidence so that further discussion could occur. All the full-text sources were coded with agreement.

Stage 4: Charting the Data

Charting the data was a two-step process: data extraction and charting the data. A data extraction form was set up within Covidence. The form included the following: stage source, source type, grade-level, if the source included children with disabilities, country, and caste information. In addition, a Strength of Strategy Coding form was set up in Covidence. This coding system was used in several earlier scoping reviews.[11] [12] [Table 2] presents the strength of coding categories and indicators. To be assigned, a source had to have all of the qualities described for a given strength level. The first 10 sources were extracted collaboratively by the authors to establish and verify consistent use of the data charting forms within Covidence. Point-by-point agreement was 0.96 for the data extraction and 100% agreement for the strength of strategy coding. The authors then independently extracted data for the remaining 30 studies. After all the data were charted, the authors met to achieve consensus on data extraction on all 40 articles. Any discrepancies were resolved through a consensus coding discussion.

Table 2 Strength of Strategy Coding

Recommendation strength	Study quality indicators
Compelling	□ Study described the intervention strategy and randomized assignment to treatment condition □ Study included pre-test post-test measures that were relevant to the intervention strategy □ Study reported statistical analysis and results (including significance and/or effect size or data that can be used to calculate these) □ Study reported positive intervention outcomes
Promising	□ Study did not describe the intervention strategy implementation adequately or did not randomly assign participants to treatment □ Study reported suggestive findings, but did not include pre-test and post-test measures, or measures were not relevant to the intervention strategy □ Study did not report enough detail about statistical analysis and results (e.g., significance or effect size) to be compelling; significance was reported but effect size was small □ Study reported neutral intervention outcomes or outcomes that did not differ from no treatment or control groups
Lacking	□ Study lacked methodological rigor or lacked descriptions of participant selection, intervention strategy, procedures, or was not designed to evaluate an intervention strategy (this includes descriptive studies, recommended practices, and/or tutorial type articles) □ Study may have reported descriptive, comparative, or correlation results, but did not include pre-test post-test measure □ Study may report data, but does not isolate intervention strategy, or does not report statistical analysis, and/or lacks rigor or practical significance □ Study does not report intervention outcomes

Stage 5: Collating, Summarizing, and Reporting Results

The authors applied a thematic framework to identify broad domains and subdomains. This involved sorting individual strategies into the domains of language or literacy, and then collating the strategies further into subdomain areas under these broad domains. Each strategy that was described in the sources underwent this process. In some instances, slight variations of strategies were described or researches used a variation of the name of the strategy (e.g., enhanced vocabulary instruction, enrich vocabulary, deliberate vocabulary teaching, teaching key vocabulary words). In such instances, the authors grouped all similar strategies together, identified common aspects that described the strategies, and refined the strategy description until an inclusive and accurate term was identified (e.g., targeted vocabulary instruction). This occurred without changing the intended meaning or the accuracy of the original source. If a strategy did not fit the inclusive term, it was pulled out and left as a standalone strategy.

Once all of the strategies were collated and sorted in broad domains and subdomains, the results were organized into a preliminary evidence map, a table which presents and organizes pertinent information about strategies identified through the scoping review. The evidence map included highest strength observed for a strategy, which was coded by identifying and indicating the highest strength observed across resources that applied a given strategy. The evidence map also included grade levels and the sources that described the strategy.

RESULTS

The research questions identified in Stage 1 were as follows: (1) What language and literacy strategies are described in the research literature and (2) What is the strength of strategies identified? Stages 2 and 3 involved identifying, selecting, screening, and reviewing sources. [Fig. 1] presents the scoping review search, process, and flow diagram in line with PRISMA-ScR guidelines.[9] The combined searches identified 3,013 sources; 2,757 were from EBSCO databases, 240 from ASHAWire, and 16 from the hand search. After duplicates were removed, the remaining 732 studies underwent title and abstract screening. Of these, 676 sources were excluded for not meeting one or more of the eligibility criteria. This was followed by full-text review of the remaining 56 sources; 16 of these were excluded upon further review for not meeting inclusion criteria. A total of 40 sources were selected for inclusion in the present scoping review.[4] [5] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24] [25] [26] [27] [28] [29] [30] [31] [32] [33] [34] [35] [36] [37] [38] [39] [40] [41] [42] [43] [44] [45] [46] [47] [48] [49] Of these, 24 were identified from the EBSCO database search, 8 were from ASHAWire, and 8 were from the hand search.

Aligned with Stage 4, the details for the 40 sources were charted; this information is available in [Table 3]. Sources included 11 clinical tutorials/recommended practice documents, 9 program or approach description, 5 nonrandomized treatment studies, 3 department of education or Indian education documents, 3 conference proceedings, 2 cross-sectional descriptive studies, 2 dissertations, 1 descriptive mixed method study, 1 cohort treatment study, 1 nonsystematic review, 1 manual or guidelines from a state, and 1 book chapter. In terms of ages or child populations described, 13 sources described strategies with preschool age children (intended for children younger than 5 years), 26 described school-age children (inclusive of kindergarten-age to 18 years of age), and 1 described both preschool and school-age children. Only 6 of the 40 sources mentioned or specifically described the intervention in relation to children with disabilities. Twenty-eight of the sources were from the United States, and 12 were from Canada. Seventeen of the sources did not specify tribes that the language and literacy strategies were intended for, 23 sources identified specific tribes—and a total of 21 tribes were mentioned. Finally, strength of strategy coding revealed 5 sources with compelling strength, 5 with promising strength, and 30 with lacking strength.

After initial charting of the 40 sources, further collating and summarizing was conducted as part of Stage 5. It should be noted that multiple strategies could have been extracted from a single source (e.g., the Romero-Little [2010] source described five different strategies). The domain of language had 43 strategies or approaches that were collated into five subdomains, including bidialectal education (n= 10), language stimulation strategies (n= 13), narrative-based strategies (n= 10), enhanced language instruction (n= 5), and other language approaches (n= 5). The domain of literacy had 49 strategies or approaches that were collated into nine subdomains, including shared book interactions (n= 6), print knowledge (n= 3), phonological awareness (n= 1), phonics (n= 2), fluency (n= 4), reading comprehension (n= 14), multi-literacy (n= 3), dialect bi-literate (n= 2), written language instruction (n= 6), and other approaches (n= 8).

[Table 4] provides a preliminary evidence map of strategies obtained in this scoping review. The evidence map is organized by broad domains and subdomains. For each strategy, detailed information is provided, including highest strength of strategy, the grade level for which the strategy is intended, and citations for sources that described the strategy. Of the 43 language strategies identified, 18 were lacking strength, 12 had promising strength, and 13 had compelling strength. Of the 49 literacy strategies identified, 27 were lacking strength, 7 had promising strength, and 15 had compelling strength.

DISCUSSION

This scoping review is the first to review sources that have described language and literacy strategies intended for Indigenous children. Forty sources were identified that met criteria, and of these the majority were non-database sources describing clinical tutorials/recommended practices, program or approach description, and conference proceedings. However, several sources were database, including some that were nonrandomized treatment studies. Very few sources, and none of the treatment studies, included children with disabilities. Overall, there continues to be a scarcity of treatment-based research on language and literacy for Indigenous children who are at risk for academic challenges or who have identified disabilities. This is despite the fact that Indigenous children have one of the lowest graduation rates in the United States, and they are proportionally the highest race/ethnicity group represented in Special Education services. To meet the educational needs of Indigenous children, more data-based research is needed to evaluate language and literacy strategies for this population.

Even with the shortage of treatment-based research with Indigenous children, this scoping review did provide a survey of the literature by identifying 43 potential language strategies and 49 potential literacy strategies described in sources. The strength supporting these potential 92 strategies varied; 28 of these strategies had compelling strength. Of strategies with compelling strength, several are frequently part of mainstream language and literacy strategies. For example, the language stimulation strategies of modeling language, use of demonstration and models while teaching, and encouraging children's questions and comments all had compelling strength and are frequently described in other language intervention packages. The same is true of the literacy strategies, and common literacy strategies that are frequently part of mainstream intervention were identified. Making cultural modifications to mainstream intervention programs and tailoring intervention strategies and procedures to a caregiver's or child's cultural background have been shown to be effective with other culturally and linguistically diverse groups.[12] [50] This approach of adapting existent mainstream intervention strategies may provide needed insight that will ultimately result in well designed, culturally consistent language and literacy strategies for Indigenous children.

Of the strategies that had promising strength (n = 19) or lacked strength (n = 45), many appeared that they could be useful and cultural modifications or supplements could be applied to these strategies. These strategies need to be further studied to support their continued use or before they are widely adopted. For example, several narrative-based strategies had cultural aspects that could be very natural for caregivers or educators to implement with Indigenous children. These included teaching listener–storyteller interactions and dialogue (comprehension and expression); providing multiple opportunities for storytelling; singing songs/stories; teaching children how to code-switch roles in storytelling in different contexts; and integrating tribal heritage and traditions into all aspects of storytelling. The same is true for the 10 bidialectal strategies and the two dialect bi-literate strategies described. What is important about the bidialectal strategies is that they support Indigenous cultural identity while supporting the acquisition of academic language that is needed for school success.

There were several strategies that had compelling strength that aligned with existent literature on language and literacy interventions. Modeling language, encouraging children to ask questions, encouraging children to make comments, using narrative based and story grammar strategies, targeted vocabulary, and targeted morphological or grammar instruction are all strategies that have been described in mainstream language approaches.[51] Reading with a focus on fluency, fluency reading with corrections, as well as reading comprehension strategies of return sweep, group read, read aloud, and repeated readings are well-established reading approaches.[51] [52] In addition, all of the print knowledge and phonological awareness strategies identified in this review are supported by scientifically based reading research.[53] [54]

Encouraging exposure and use of Indigenous languages was mentioned by 19 different sources, and needs to be further described and understood. It should be noted that 17 of the sources did not specify the tribe or Indigenous languages of the Indigenous population included or described in the source. In some instances, this may have been because more than one tribal group or language was included in the source. When studying language and literacy in bilingual children, it is important to have detailed information on language exposure and usage. More research is needed that is inclusive of a wide range of Indigenous languages. Careful consideration is needed by both researchers and clinicians when studying or intervening with Indigenous languages. For researchers, reporting languages used by study participants must be included as part of scientific reporting. For clinicians, an evidence-based decision-making approach must be used when deciding how to include Indigenous languages as part of language and literacy strategies.

With five nonrandomized treatment studies and one cohort treatment study identified, this scoping review found a shortage of language and literacy treatment studies with Indigenous children. Additionally, there were no treatment studies that evaluated language and literacy intervention approaches for children with identified disabilities, even though Indigenous children are highly represented in special education programs. The shortage of intervention research with Indigenous children is a recognized area of concern.[55] This parallels a field-wide shortage of treatment-based language and literacy interventions.[56] The lack of evidence relating to language and literacy strategies with Indigenous children is concerning for several reasons. One of these is that high-quality research-based strategies and interventions are needed for Indigenous children, given the projected increase in this population. This research is also needed to improve educational programming and access for Indigenous children, which is evidenced by the current trends of lower graduation rates and disproportionate special education representation.

In the spirit of evidence-based practice, speech-language pathologists (SLPs) must integrate information and act in accordance with the best available evidence. This scoping review identified 28 compelling language and literacy strategies, which can be applied and adapted to meet the needs of Indigenous children. There were also 19 promising language and literacy strategies, which can be applied but should be closely monitored in a case-by-case scenario to evaluate effectiveness and cultural appropriateness. Finally, nearly half of the strategies identified were lacking. Clinicians need to evaluate these closely to establish if they should be applied, including the rationale for their use, which may include evidence from research with other populations, as well as their observed effectiveness and their cultural appropriateness. The lack of research with children with disabilities is concerning; however, when faced with the lack of research to support practice, SLPs can draw upon related bodies of research to identify promising approaches. The compelling and promising strategies described in this scoping review can be trialed with children with disabilities and evaluated on a case-by-case basis to establish their effectiveness. This also aligns with the American Speech-Language-Hearing Associations' position on the critical and direct role that SLPs have in developing, implementing, and collaborating with others in literacy instruction for children and adolescents.[57]

LIMITATIONS

There are several limitations to the current study. As a field more research is needed to provide higher levels of evidence for language and literacy strategies with Indigenous populations. A limitation to this scoping review was that the strength of strategy coding was based on the highest strength level found in any of the sources that included a description of a particular strategy. This means that strength of strategy coding of compelling could be assigned to a strategy that was described by 10 studies, only 1 of which had compelling strength. On a related note, there were only 5 studies that were ranked as having compelling strength, and those studies described a total of 28 strategies that were coded as compelling. An additional limitation has to do with the practicality of implementing the abundance model in the field. The abundance model may be a culturally consistent approach to understanding Indigenous children, but unfortunately, special education is inherently deficit based, and defined by legal mandates and guidelines that are deficit focused. For an abundance model to work, the policies and guidelines for special education processes would need to be reconsidered by policy makers and school personnel.

CONCLUSION

Promoting equity in speech and language services to Indigenous children requires SLPs to continually reflect on their cultural competency. Self- reflection is an important component of cultural competency, and leads to openness to shifting one's perspective or framework. The authors of the current study also believe that the abundance model will help SLPs make this perspective shift. The abundance model's focus on positive development; identifying and building up student and family assets; and highlighting the child's interest, strengths, skills, talents, and competencies can set the stage for intervention planning. Furthermore, the sources and strategies identified in this scoping review provide valuable information that can be used to guide intervention planning with Indigenous children and families. Combining this knowledge with meaningful dialogue with families and communities will lead to cultural modifications to existent strategies or the development of new strategies and ultimately to culturally consistent practices that will support the language and literacy of Indigenous children.
