• Impact of the Self-Learning Module in Relativity (SLM-R) on students' conceptual understanding of Einstein’s theory (2026) · doi

  This research endeavor acknowledges the various limitations that may affect the results. First, the study does not intend to compare the effects of the gender gap in the intervention. Therefore, any discussion of this aspect may not be addressed, as it primarily emphasizes the effect of SLM-R on classroom use. Second, the design, development, and validation of the material are excluded from this study. Hence, articulations of how the SLM-R was compared to existing materials are limited, and a separate study was conducted to address this. Third, the limited number of participants may influence the generalizability of the results. Hence, increasing the sample size could expand the generalizability of the findings. Fourth, the statistical tools employed in this study primarily focused on the effectiveness of the instructional material, which may limit the robustness of the data interpretation. However, potential threats to internal validity were carefully addressed by implementing actions to minimize them. Similarly, qualitative data were collected to support the claims.

• A Needs Analysis of Teacher Experiences and Literacy Practices in Supporting Multilingual Learners in Borderland Schools (2026) · doi

  Several limitations can be identified when interpreting the findings of this study. First, the sample size was small (n = 16), which limits the statistical power of the research and reduces the ability to generalize the findings to broader populations. The small sample also affects the stability of statistical estimates and limits the reliability of subgroup comparisons. This issue was further compounded by the number of analyses conducted due to the lack of internal consistency across measures. Although the Holm–Bonferroni correction indicated that none of the analyses reached statistical significance, this may reflect limited statistical power associated with the small sample rather than the absence of meaningful effects. Furthermore, we were unable to examine potential differences based on key instructional and contextual variables, such as the percentage of multilingual students in a classroom, the proportion of instructional time dedicated to language or literacy instruction, or the grade levels taught. Another imitation is that the study involved multiple statistical comparisons, which increases the risk of Type I errors. Given the exploratory nature of this pilot study, these analyses were intended to identify potential patterns rather than establish definitive relationships. Future studies with larger samples will be better positioned to apply more robust statistical procedures and confirm whether the observed patterns are replicated. Some subscales demonstrated internal consistency estimates below the commonly recommended threshold of α = .70. To address this limitation, analyses were conducted at the item level rather than the scale level for these domains to avoid drawing conclusions from unreliable composite scores. This approach allowed for a more cautious interpretation of the data while acknowledging that further psychometric refinement of the instrument is needed. Future research with larger samples will allow for more robust evaluation of the factor structure and reliability of the instruments. In addition, the qualitative synthesis of open-ended responses was conducted by the lead author and intended to provide a high-level descriptive summary of participant perspectives. While this approach allowed for an initial overview of common themes, future research could incorporate multiple http://ijlter.org/index.php/ijlter 623 coders and formal reliability procedures to strengthen the rigor of qualitative analysis. Another limitation is that the data are cross-sectional and exploratory, which limits the ability to draw causal inferences about the relationships across teacher characteristics, practices, and perceptions. The findings should therefore be interpreted as descriptive patterns rather than definitive evidence of underlying mechanisms. A further limitation includes participation bias, as those who chose to participate may have had stronger opinions or greater interest than those who did not. While mandatory participation could reduce this bias, it may not be feasible or ethical, thus the findings should be interpreted accordingly.

• Reading gains and gaps: students with reading difficulties’ response to an open educational reading intervention (2026) · doi

  There are several limitations to our current study. First, the research design does not allow for causal claims and at best provides correlational conclusions (Gast and Ledford, 2014). Another limitation is the external validity of our study. As has been previously reported in studies in England, girls are less likely to be identified for specific learning difficulties services (Daniel et al., 2026; Daniel and Wang, 2023) and none of the participants teachers recommended were females. This could be due to meaningful gender differences or gender bias. Another limitation concerns the demographic characteristics of our sample. All participants were White, monolingual males; this homogeneous sample restricts the findings. The absence of students from multilingual or racially diverse backgrounds limits our ability to consider how the intervention may function across varied cultural and linguistic contexts. However, it is important to note that the aim of this study was not to obtain a representative sample, but to explore individual patterns of responsiveness to intervention within a specific instructional context among primary school children with reading difficulties. the generalizability of Moreover, given that all five students in our sample came from one private school, the demographic of our sample was mostly homogenous. However, the reading profiles of our sample was heterogenous; that is the level of severity of reading difficulties varied among our sample and similar variability has been reported remedial instruction to students with reading difficulties in small groups (Daniel et al., 2024b) and in past literature of reading profiles (Capin et al., 2021; Daniel and Barth, 2023). In addition, focus educators provide schools where in feedback with educators highlighted that although group students attended a private school, the additional support they received focused mostly on decoding skills and was delivered only once or twice a week, lacking the intensity recommended in current research. This pattern is comparable to support reported in some public schools (Daniel et al., 2024b; DfE, 2024), suggesting that the challenges observed here are not unique to private school settings. Additionally, potential measurement error in the oral reading fluency and MAZE assessments may have impacted the accuracy of our estimates of students’ progress. Although progress- monitoring procedures were implemented with fidelity and each progress monitoring assessment administered a previously unseen passage, inherent test–retest effects and variability in student performance can contribute in individual scores. to error variance Another limitation concerns the nature of open educational programs themselves. Although adaptability is a key strength of open educational programs, the 30-minute session limit in this pilot restricted opportunities for modification. For example, Students 2 and 3 could have benefited from the word-reading extension activities but we could not implement these within the allotted time. Future research should examine how extended sessions or flexible to incorporate such adaptations more effectively. scheduling might allow teachers A further limitation is that social validity data were collected anonymously, which precluded to individual student characteristics or intervention responsiveness; future studies should consider linking social validity responses to individual outcome profiles to better understand variability in student perceptions. linking ratings lower Additionally, while freely available interventions reduce financial barriers, their successful adoption requires adequate teacher training and ongoing support. In our prior work (Daniel et al., 2024b), we found that the scripted teacher lesson copies included with the lessons allowed educators to implement the program with relative ease following a one- hour workshop on how to use the materials. Nonetheless, systematic broader approaches. Future funded studies could embed dissemination and training as a central component of intervention research, providing researchers with resources to develop online media, exemplar lesson demonstrations, and practical guidance to support teachers in utilizing open educational resources with fidelity in diverse school contexts. dissemination will require more
