1
00:00:04,200 --> 00:00:08,600
"We are tired from teaching, and tired again from the calculator."

2
00:00:11,100 --> 00:00:16,733
Every term, public school teachers check every paper by hand.

3
00:00:16,813 --> 00:00:22,586
They tally every item, and do the math on a calculator.

4
00:00:22,666 --> 00:00:27,417
In a country where most ten-year-olds struggle to read,

5
00:00:27,497 --> 00:00:36,113
by the time the numbers are ready, there is no time left to fix what the class missed.

6
00:00:39,363 --> 00:00:43,568
Meet Tanglaw, by AHA X.

7
00:00:44,163 --> 00:00:47,021
Tanglaw means guiding light.

8
00:00:51,663 --> 00:00:55,346
It does one loop, end to end:

9
00:00:55,426 --> 00:00:58,748
check the papers, find what the class missed,

10
00:01:00,026 --> 00:01:04,127
plan the lesson that fixes it, and report it.

11
00:01:04,207 --> 00:01:06,647
All on the teacher's phone.

12
00:01:09,007 --> 00:01:14,883
Teachers with a printer make answer sheets for the whole class in one tap.

13
00:01:19,607 --> 00:01:25,298
One master can be photocopied, and every copy still scans.

14
00:01:29,207 --> 00:01:35,630
Snap a photo. Tanglaw reads it on the phone, in under a second,

15
00:01:35,710 --> 00:01:37,930
even with no signal.

16
00:01:38,010 --> 00:01:44,211
Anything unclear is flagged for the teacher to fix in one tap.

17
00:01:49,910 --> 00:01:57,122
No printer? Tap the items you marked wrong, about forty seconds a paper.

18
00:01:57,202 --> 00:02:00,699
Or photograph the checked paper;

19
00:02:00,779 --> 00:02:06,609
the name is hidden first, and AI reads it once there's signal.

20
00:02:07,159 --> 00:02:10,099
Instantly, the item analysis.

21
00:02:10,179 --> 00:02:12,851
The Mean Percentage Score.

22
00:02:12,979 --> 00:02:17,044
The three skills the class missed most.

23
00:02:18,279 --> 00:02:23,355
Who needs support, who's close, who's got it.

24
00:02:23,435 --> 00:02:28,708
Even the wrong answer most learners chose.

25
00:02:30,735 --> 00:02:38,040
Then the plan. A remedial lesson in DepEd's ILAW format,

26
00:02:38,120 --> 00:02:40,828
with one activity for each group,

27
00:02:40,908 --> 00:02:44,963
ready offline and ready for ARAL sessions.

28
00:02:45,043 --> 00:02:49,062
With signal, it's tailored to this class.

29
00:02:52,643 --> 00:02:59,298
And the files the coordinator expects: their Excel calculator, already filled in,

30
00:02:59,378 --> 00:03:04,279
a one-page summary, and the plan, shared in a tap.

31
00:03:06,878 --> 00:03:09,504
It all works offline.

32
00:03:10,378 --> 00:03:14,025
And learner names never leave the phone.

33
00:03:14,978 --> 00:03:19,322
Every screen in English or Filipino.

34
00:03:23,772 --> 00:03:27,466
Tanglaw, by AHA X.

35
00:03:28,372 --> 00:03:31,044
Less tallying. More teaching.
