Just out: Secondary Research in Applied Linguistics: A Meta-Systematic Review of the Last Three Decades BY : Hessameddin Ghanbar, Marzieh Dehghan-Chaleshtori, and Mohammad Amini Farsani
This is our most recent article, presenting the most comprehensive meta-review to date on secondary research in the field, synthesizing 30 years of publications (n = 1,560). Through systematic searches of five prestigious databasesāWeb of Science (WoS), Scopus, LLBA, PsycINFO, and ERICāwe identified 14 main types of secondary research along with several additional subtypes, and mapped more than 40 distinct research foci. To guide and inspire future work, the article also includes four integrated appendices serving as a detailed methodological resource for conducting similar studies.

What is the Noncentrality Parameter? (A new part added to the most recent version of SPSS in ANOVA's tables
The noncentrality parameter (Ī») is a value used in noncentral distributions (like the noncentral F-distribution) to compute:
Observed power
Confidence intervals
Critical values for hypothesis tests
It quantifies how far the true distribution is from the null distribution. When Ī» = 0, the F-distribution is central (i.e., under the null hypothesis).
A larger Ī» means a larger effect ā the further the true mean is from the null.
Noncent. Parameter (Ī»): A theoretical value that determines the shape of the F-distribution under the alternative hypothesis.
Higher Ī»>>>Greater deviation from null ā stronger evidence for the effect.
Used for>>>Calculating observed power and confidence intervals.
Two Corrections for Cohen's D in SPSS's Tables and their Functions
ā¶ļø Hedge's Correction:
š¹ When the sample size is small (e.g., n=8 in each group), we can use Hedge's Correction. That is a variation of Cohen's d which includes a correction for small sample sizes. This adjustment makes the data analysis more accurate when sample sizes are below 20 per group.
...................
ā¶ļø Glass's delta:
š¹Because group variances were unequal, we calculated Glass's delta instead of Cohen's d. Glass's delta measures effect size using the control group's standard deviation, making it appropriate when variances differ.
Dear Colleagues,
We are delighted to share that our new book, "Key Concepts in Syllabus Design and Materials Development," has just been published!

Dear Colleagues,
Greetings. You might be interested in this monograph, the idea of which came to my mind four years ago after being enlightened by Yin et al.'s (2019) study on the Dispositions towards Loving Pedagogy (DTLP) scale: Instrument development and demographic analysis.
The new scale development and validation might be suitable for EFL/ESL contexts.
