PSLE Science Reality Lab Vol No.156 | “R² = 0.90” — Does That Mean 90% of the Predictions Were Correct?
PSLE-SCI-REALITY-0156. A Primary 5/6 guide to R² in scientific reports: why R² = 0.90 does not mean 90% of predictions are correct, and why residuals, validation and range still matter.

The Tutor Handbook Vol No.0189 | The Tutor Case-Mix Allocation Gate — How a Tuition Programme Distributes Diagnostically Intensive Learners and Groups Without Treating Equal Headcount as Equal Work
THB-0189 — How tuition programmes allocate tutor portfolios by current decision complexity as well as headcount, balancing diagnostic ambiguity, transitions, coordination and group divergence without labelling learners as difficult.

The Tutor Handbook Vol No.0188 | The Contrast-Case Gate — How a Tutor Chooses Which Two Examples to Put Side by Side So the Learner Notices the Decisive Difference Without Turning Comparison Into Extra Noise
THB-0188 — How tutors choose, align and sequence two comparison cases so learners notice a decisive structural difference or similarity, then verify the distinction on a fresh third case.

PSLE Science Reality Lab Vol No.155 | “This Dot Is Beyond the Box-Plot Whisker” — Does That Mean the Measurement Is Wrong?
PSLE-SCI-REALITY-0155. A Primary 5/6 guide to box-plot outlier flags: why a point beyond a whisker is evidence that a value is unusual, not automatic proof that the measurement is wrong.

The Tutor Handbook Vol No.0187 | The Implementation-Feasibility Gate — How a Tuition Programme Decides Whether an Evidence-Informed Teaching Routine Can Actually Fit Ordinary Tutor Time, Materials and Learner Variation Before Blaming Non-Use on Fidelity
THB-0187 — How tuition programmes distinguish a sound practice that is operationally infeasible from poor tutor fidelity, then redesign time, materials, support or scope without removing the active ingredient.
