Abstract

This paper systematically reviews informal Design Thinking (DT) models in Science, Technology, Engineering, and Mathematics STEM education and performs a meta-analysis to assess their impact on students' creativity. Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, data sources include eighteen peer-reviewed research papers from 11 countries, representing more than 1,600 students. The meta-analysis, using a random-effects model, assessed the effect size ( ES ) of informal DT in enhancing creativity in STEM education and revealed a significant improvement compared to traditional classroom education ( d = 0.876, p < 0.001). This study found that several moderator variables influenced the impact of informal DT on students’ creativity, including teaching methodology, assessment methods, subject area, student group size, course duration, and grade level. Moderator analysis revealed that the combination of direct and indirect assessment ( d = 1.163, p = 0.010) and triangulation assessment methods ( d = 1.009, p < 0.001) had the highest effect size and significance. Student study sizes of 30 or more ( d = 1.143, p < 0.001) were most effective, and informal DT employed for the subject areas like STEM ( d = 1.165, p < 0.001) and science/math ( d = 0.988, p < 0.001) exhibited the greatest creativity improvements. However, the study location of the students was not a significant moderator. This study provides valuable insights into existing literature. It aids academicians in designing, developing, and implementing successful STEM-based informal DT models in STEM education, and aids educators in developing innovative approaches to enhance creativity.

TL;DR

This meta-analysis of 18 peer-reviewed studies from 11 countries finds that informal Design Thinking (DT) models in K-12 STEM education significantly improve students’ creativity compared with traditional classroom settings (d = 0.876, p < 0.001). Moderator analyses show the strongest effects for combined direct/indirect or triangulation assessment, larger student groups, STEM or science/math subject areas, and courses lasting 5–15 weeks, while study location was not a significant moderator.

Key findings

  • Overall, informal DT had a high positive effect on creativity: n = 18, d = 0.876, 95% CI [0.547, 1.205], p < 0.001; 13 of 18 studies showed statistically significant effects favoring the informal model.
  • Assessment method mattered: direct + indirect assessment had the highest effect (n = 2, d = 1.163, p = 0.010), followed by triangulation (n = 8, d = 1.009, p < 0.001), direct (n = 5, d = 0.723, p < 0.001), and indirect (n = 3, d = 0.620, p = 0.001).
  • Group size and subject area moderated outcomes: groups of more than 30 students had d = 1.143, p < 0.001; STEM had d = 1.165, p < 0.001; science/science & math had d = 0.988, p < 0.001.
  • Educational level and duration also mattered: middle school had d = 1.098, p < 0.001 and high school d = 0.908, p < 0.001; the 5–15 week duration had the highest course-duration effect (n = 7, d = 1.067, p < 0.001). Study location was not a significant moderator (Q_B p > 0.05).

Methods

  • PRISMA-guided systematic review and meta-analysis; searches across Web of Science (n = 114), ERIC (n = 271), and Scopus (n = 214) yielded 599 documents, from which 18 peer-reviewed empirical studies published 2005–2024 met inclusion criteria, representing 11 countries and more than 1,600 students.
  • Random-effects meta-analysis using Comprehensive Meta-Analysis Software Version 4, with Cohen’s d as the effect-size index and DerSimonian and Laird methods; moderator variables were teaching methodology, assessment methods, school level, course duration, subject area, study location, and student group size.
  • Inter-rater reliability was substantial (Cohen’s kappa = 0.765, p < 0.001); included studies scoring 18–21 out of 27 on the Downs and Black checklist were considered high quality.

Limitations

  • The paper states that only peer-reviewed empirical articles were included, excluding books and conference papers; few articles met the inclusion criteria, limiting depth and generalizability; DT definitions/implementations and creativity assessment tools were heterogeneous; elementary-level studies were insufficient for statistically significant conclusions; and cultural/contextual variables were not examined.
  • The text also makes evident high heterogeneity (Q = 317.492, df = 17, p < 0.001; I² = 95%; τ² = 0.455; τ = 0.675), with a wide prediction interval of −0.598 to 2.350.
  • Several moderator subgroups were very small (e.g., n = 2 for direct + indirect assessment, engineering & technology, technology, West Asia, and Southeast Asia), and some confidence intervals crossed zero, so those subgroup estimates should be interpreted cautiously.

  • The paper relies on this without support.

    The 18 included studies are sufficiently comparable in their definitions and measures of creativity to be pooled in a meta-analysis.

    “This meta-analysis presents a novel contribution to research by synthesizing data from eighteen articles selected from a pool of 595 published between 2005 and 2024.”
  • The paper relies on this without support.

    The moderator categories (e.g., assessment methods, subject area, group size) are coded consistently and validly across the included studies.

    “A moderator analysis also evaluates the influence of variables such as Subject Area, Teaching Methodologies, Assessment Methods, Educational Level, Course Duration, Study Location, and Group Size.”
  • The paper relies on this without support.

    The search keywords and databases captured the relevant literature on informal DT in STEM K-12.

    “a total of 599 documents were identified across different databases: Web of Science (n = 114), ERIC (n = 271), and Scopus (n = 214).”
  • The paper relies on this without support.

    The effect sizes reported in the primary studies are unbiased estimates of the true effect.

    “The meta-analysis, using a random-effects model, assessed the effect size (ES) of informal DT in enhancing creativity in STEM education and revealed a significant improvement compared to traditional classroom education (d = 0.876, p < 0.001).”
  • The authors state this as an assumption.

    The true effect sizes in the combined studies are normally distributed around a common mean, with between-study variance estimated using a weighted average of within-study variances.

    “This method assumes that the true ESs in the combined studies are normally distributed around a common Mean, with a certain between-study variance estimated using a weighted average of the within-study variances.”
  • The authors state this as an assumption.

    All studies in the analysis report the same true effect size.

    “Based on the assumption that all studies report the same true effect size, Q would be equal to the degrees of freedom, which are calculated as the Number of studies minus one.”
  • The authors state this as an assumption.

    The true effects are normally distributed in d units.

    “We can estimate the prediction interval of -0.598 to 2.350 if we assume that the true effects are normally distributed in (d units).”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Medium-group significance conflicts with its confidence interval

    Major

    The reported 95% confidence interval for groups of 10 to 30 includes zero, although the paper reports p = 0.032 and says all group sizes are significant.

  • One-to-four-week significance conflicts with its confidence interval

    Major

    The 1-4-week subgroup's reported 95% confidence interval includes zero, despite its reported p < 0.001 and the claim that all duration subgroups are significant.

  • Six-to-twelve-month significance conflicts with its confidence interval

    Major

    The 6-12-month subgroup's reported 95% confidence interval includes zero, yet its p-value is reported as less than 0.001 and the paper says every duration subgroup is significant.

  • Engineering significance conflicts with its confidence interval

    Major

    Engineering's reported 95% confidence interval includes zero, while its reported p < 0.001 and the text call the result significant.

  • Three studies are assigned conflicting course durations

    Minor

    Chiu, Ellis, and Solodikhina are grouped under 6-12 months in the literature review but are also cited under the 1-4-week subgroup in the discussion.

  • Technology subgroup has two different p-values

    Minor

    The subject-area findings give p = 0.365 for technology, while the discussion gives p = 0.519 for the same effect size.

  • Overall heterogeneity is mislabeled as between-group heterogeneity

    Minor

    The discussion calls approximately 317.5 the moderator between-group statistic, Q B, while Table 4 defines that value as the overall statistic, Q T, and reports separate Q B values for individual moderators.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-23.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-23.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
