Quality of Online Science Info. Varies by Language

The Internet can alleviate inequality in science literacy. Nevertheless, structural factors appear to underlie disparities in science literacy and in Internet access and use.

Among these, the “language divide” partly determines how successful users are in their Internet use depending on the languages they speak.

So far, little is known about the availablity of scientific information in different languages.

Research Question

Does the quality of online scientific information vary between languages and scientific fields?


We collected online search results regarding scientific terms in English, Hebrew, and Arabic, analyzed their content, and rated their scientific and pedagogical quality.

Statistical methods included univariate and multivariate ANOVA and Linear Discriminant Analysis (LDA).


Note: The Linear Discriminant Analysis was conducted by my co-author, Dr. Eyal Nitzany.

Findings and Discussion

Findings indicate that searches in English yielded overall higher quality results, compared with Hebrew and Arabic, but mostly in pedagogical aspects, rather than scientific ones.

Clustering the results by language yielded better separation than clustering by scientific field. This finding points to a “language divide” in access to online science content.

These findings should encourage scientific communities and institutions to mitigate this language divide.
