Missing the kids

-
These pictures of my kids are taken separatey when they were of the same age (around 8 months). This reminded me of how genetics played a role in diversity. I remembered the class website of Miss Stacy Baker doing the meiosis dance, with emphasis on crossing over during prophase I in a process called synapsis.

Interestingly, after attending an international conference in math and science education, my desire to learn more about molecular biology and genetics has been burning much. I am particularly curious about the chromosomal and mitochondrial DNA.

While what I presently know is that apart from the nucleus the chloropolast and mitochondrion of the cell have their own DNAs, I know nothing much deeper than that. But it was an eye opener to me that I met a scientist telling me that what constitutes the DNA of our children are mine and my wife's but as to their mitochondrial DNAs, they are all their mom's. This indeed has a far-reaching implication in forensic science.

And since this is my second week in the city, I have been missing these two cute babies. Mwah!

Boom in Brooms: The Potentials of Tiger Grass Industry

-
Image
Marigondon Norte is a tiger grass growing village in San Andres, Romblon. It is located in the northeastern part of the municipality along the lush and rolling mountains of central Tablas. It is bounded by San Agustin in the east and Calatrava in the north. It has an approximate total land area of 2,800 hectares and is home to about 221 households of 1,175 (NSO, 2005) people. It is a typical remote agricultural Philippine village, barely reached by technological breakthroughs because of its rugged trails and far-flung distance (about 14-18km) from the town proper. Although passable to robust motorcycles and sturdy vehicles, transportation remains a major problem because large portions of the service road are still in bad shape and condition.

Lightning and Mushroom Growth

-
One time in my class several years ago, a student asked me why do mushrooms flourish after lightning. All I could mutter was, mushroom absrobed the nitrogen in the air because there is no way it can be directly absorbed but through that process. (lols). Here's one that gives a better explanation:

Rubrics

-

As opposed to most traditional forms of testing, performance assessment does not have clear-cut or wrong answers. Rather there are degrees to which a student is successful or unsuccessful. This can be accomplished by creating rubrics. Airasian, (1991) Popham, (1995) and Stiggins, 1994) were cited by Brualdi (2000) on their definition of rubric as a rating system by which teachers can determine at what level of proficiency a student is able to perform a task or display knowledge of a concept. With rubrics, the different levels of proficiency for each criterion can be defined. Scoring rubrics are descriptive scoring schemes that are developed by teachers or other evaluators to guide the analysis of the products or processes of students’ efforts (Brookhart, 1999). Scoring rubrics are typically employed when a judgment of quality is required and maybe used to evaluate broad range of subjects. In the article by Heidi Goodrich Andrade published in American Leadership in 1999, he defined rubr...
