I'm not sure if this is the original article you were reading, but he cites Ramba"m and Talmud Kiddushin (no pun, but "Talmud" here has a different definition). It seems that "Talmud" means "learning" and not "teaching".
אין לך מצוה בכל המצות כולן שהיא שקולה כנגד תלמוד תורה אלא תלמוד תורה
כנגד כל המצות כולן שהתלמוד מביא לידי מעשה, לפיכך התלמוד קודם למעשה בכל
מקום. (הלכות תלמוד תורה ג:ג)
My translation (I am intentionally not translating the term Talmud Torah, here, as it is not apparent, yet what the translation really is :
There is no mitzvah that is equal to Talmud Torah. Rather Talmud Torah is equal to all the other mitzvoth, for Talmud leads to performing. therefore, the Talmud precedes performing in every situation.
(See the linked article that resolves a contradictory statement that Ramba"m makes.)
In his introduction to the Commentary to the Mishnah (pp. 22 –
23), Rambam writes (excerpted):
. ולכן תמצא המצוה בכל התורה, ולמדתם ואחר כך לעשותם, התלמוד קודם למעשה,
כי בתלמוד יבוא לידי מעשה ואין המעשה מביא לידי תלמוד, וזהו אמרם ע"ה
שהתלמוד מביא לידי מעשה
My translation (Here, I will translate Talmud Torah, as it seems quiet clear what it means based on the Torah term that he is using.)
Therefore, you will find this mitzvah stated everywhere in the Torah in the format, "You shall learn them" and then it says, "Do them". The learning precedes the doing. Because learning will lead to doing and not doing leads to learning.
One of many examples from the Torah regarding the order of the primciple Ramba"m states ולמדתם ואחר כך לעשותם is
Deuteronomy 5:1:
וַיִּקְרָ֣א מֹשֶׁה֮ אֶל־כָּל־יִשְׂרָאֵל֒ וַיֹּ֣אמֶר אֲלֵהֶ֗ם שְׁמַ֤ע
יִשְׂרָאֵל֙ אֶת־הַחֻקִּ֣ים וְאֶת־הַמִּשְׁפָּטִ֔ים אֲשֶׁ֧ר אָנֹכִ֛י
דֹּבֵ֥ר בְּאָזְנֵיכֶ֖ם הַיּ֑וֹם וּלְמַדְתֶּ֣ם אֹתָ֔ם וּשְׁמַרְתֶּ֖ם
לַעֲשֹׂתָֽם׃
And Moses called unto all Israel, and said unto them: Hear, Israel, the statutes and the ordinances which I speak in your ears this day, that you may learn them, and observe to do them.
See also a cross ref to beginning of Sefer Hachinuch 419:1 who cites this verse, among others. He says that there is a mitzvah to both learn AND teach/ But it is obvious that you can't relay the info to your children unless you have learned it yourself, first.
