Although the pandemic was officially declared over by the World Health Organization in May 2023, many questions remain about the long-term impact of the pandemic on K-12 education. The purpose of this study was to gain a deeper understanding of the continued impact of the pandemic among school-based speech-language pathologists (SLPs) at the onset of the 2023-2024 school year.METHODThis study involved a survey of 193 school-based SLPs between September and December 2023. The results of the survey were analyzed both qualitatively and quantitatively to identify key themes and trends related to how the pandemic influences both their direct work with students and how they approach and reflect on their own careers. Multiple efforts were made to ensure the credibility and trustworthiness of the analysis.RESULTSThis survey found that although many SLPs in public schools have largely returned to prepandemic practices, most perceived that the pandemic continues to influence their work in key ways. Specifically, survey responses highlighted the altered needs of students (e.g., social-emotional needs and academic gaps) as well as changes to how SLPs reflect on their careers as professionals serving communities.CONCLUSIONThe results of this study indicate that although the most obvious effects of the pandemic are no longer visible in schools (e.g., masking, distancing, relying on virtual services), the pandemic continues to make the work of school-based SLPs more challenging as they navigate the disconnect between the postpandemic demands of their work and prepandemic expectations, policies, and regulations.","PeriodicalId":54326,"journal":{"name":"Language Speech and Hearing Services in Schools","volume":"30 1","pages":"1-26"},"PeriodicalIF":2.4,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142231277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple regression was used to examine the effects of self-efficacy, job satisfaction, caseload size, and geographic location on the number of data sources used in eligibility decision making and to examine the effects of caseload size and job satisfaction resources on SLP self-efficacy.RESULTSSLPs, on average, reported using 7.98 data sources to support eligibility determinations. Standardized tests, conversation samples, and review of records were most used, and literacy assessments were used least. Results of multiple regression models indicate that SLPs with higher self-efficacy scores reported using significantly more data sources and that SLPs with higher job satisfaction indicated significantly higher self-efficacy.CONCLUSIONSThis study affirms self-efficacy as a strong resource for school-based SLPs and that it is, in fact, related to the number of data sources used in eligibility decisions. Limited literacy assessment was reported, despite the SLP's critical role in an educational setting. Job satisfaction as a predictor of self-efficacy and self-efficacy, in turn, as a predictor of data sources underscore the need for SLPs to advocate for work conditions that support their work.","PeriodicalId":54326,"journal":{"name":"Language Speech and Hearing Services in Schools","volume":"17 1","pages":"1-15"},"PeriodicalIF":2.4,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142171315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is unclear whether FVMC scores vary as a function of language sample elicitation contexts. The current study evaluated the performance on FVMC in preschool-aged children across different language sampling contexts.METHODParticipants were 38 English-speaking children who were between the ages of 3 and 4 years and below the mastery level of tense usage in three language sampling contexts, including conversation (free-play), picture description, and narratives (story retell). FVMC from each sampling context was computed by calculating the overall accuracy of copula be, auxiliary be, third-person singular present -s, and past tense -ed combined. A linear mixed-effects model comparison was carried out to determine the effect of sampling context on FVMC scores.RESULTSAfter controlling for child age, mean length of utterance, and the number of obligatory contexts for FVMC scoring, FVMC scores were significantly higher in conversation than in picture description and narratives. In addition, FVMC scores across the three sampling contexts were significantly correlated (rs ≥ .62, p < .001).CONCLUSIONSAlthough children's performance on FVMC relative to each other was quite stable across sampling contexts, FVMC scores may vary with sampling contexts. As compared to picture description and narratives, conversation may not adequately capture the limitation in preschoolers' tense development that is important for therapeutic planning.","PeriodicalId":54326,"journal":{"name":"Language Speech and Hearing Services in Schools","volume":"1 1","pages":"1179-1187"},"PeriodicalIF":2.4,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142448011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is broad evidence that semantic depth is an important contributor to word learning, especially when semantic cues are repeated and spaced out over time. Perceptual learning and production learning each support word learning sometimes, but not in all cases. The purpose of this study was to examine all three learning mechanisms within a single experimental paradigm.METHODThirty-six typically developing preschool children completed the experiment. They were familiarized with 16 novel words that were contextualized as alien names. These aliens came in four sets, each set comprising one base alien and three modified aliens marked by suffixes. Children completed four familiarizations: two in which they simply listened to the alien names (perceptual learning) and two where they repeated the alien names (production learning). Those conditions were crossed with a semantic depth manipulation (aliens with and without verbal semantic cues). Following each familiarization, referent identification and confrontation naming tasks were completed to assess learning.RESULTSChildren were able to identify more alien referents following familiarizations with semantic depth. There were no significant effects of either perceptual learning or production learning.CONCLUSIONSThis study confirms and expands on the benefits of semantic depth, but the results are unclear about the relative importance of perception and production to word learning. Nevertheless, the study suggests benefits to simultaneously studying multiple factors related to word learning.","PeriodicalId":54326,"journal":{"name":"Language Speech and Hearing Services in Schools","volume":"3 1","pages":"1085-1098"},"PeriodicalIF":2.4,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142448010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
