A Purpose for Social Studies - 1 views

  • social studies is about understanding things, and not very much about learning skills.
  • social studies should be part of the curriculum for the purpose of helping students understand human interactions that occurred in the past, are occurring now, and that are likely to occur in the future. The reason for these understandings is they may help students develop and nurture values that will make it more likely that they will be able to determine for any situation what the right thing is and do it, especially when doing the right thing is hard to do. It is about decency, respect, courage and honor. This is not a difficult idea to understand, but it can take a lifetime to appreciate.

WHAT IT MEANS TO UNDERSTAND SOMETHING -  Part 1 - 0 views

  • I even require that my students to begin their lesson plans with the phrase “I want my students to understand…” 
  • Reasons are important!
  • I ask each student to complete these two sentences: 1. "I know about or understand"_______________________ 2. "I know how to"_________________________________ The students are told that these understanding and skills can be about anything, and not necessarily social studies, which is what I teach. Usually, students are comfortable expressing what they understand and know how to do when the context for doing so is not threatening. When they have finished writing the completions to the sentences, there is period when I ask each student to tell the class what it is they understand and know how to do. During the process, I question them about how they came to understand whatever they wrote and how they learned the skill they indicated. It is an interesting exercise.

  • Following that, I give an assignment
  • to write a description of what a person would have to DO in order for the student to make an inference that the person actually understood what the student said he or she understood.

    The Altai region of southern Siberia has played a critical role in the peopling of northern Asia as an entry point into Siberia and a possible homeland for ancestral Native Americans. It has an old and rich history because humans have inhabited this area since the Paleolithic. Today, the Altai region is home to numerous Turkic-speaking ethnic groups, which have been divided into northern and southern clusters based on linguistic, cultural, and anthropological traits. To untangle Altaian genetic histories, we analyzed mtDNA and Y chromosome variation in northern and southern Altaian populations. All mtDNAs were assayed by PCR-RFLP analysis and control region sequencing, and the nonrecombining portion of the Y chromosome was scored for more than 100 biallelic markers and 17 Y-STRs. Based on these data, we noted differences in the origin and population history of Altaian ethnic groups, with northern Altaians appearing more like Yeniseian, Ugric, and Samoyedic speakers to the north, and southern Altaians having greater affinities to other Turkic speaking populations of southern Siberia and Central Asia. Moreover, high-resolution analysis of Y chromosome haplogroup Q has allowed us to reshape the phylogeny of this branch, making connections between populations of the New World and Old World more apparent and demonstrating that southern Altaians and Native Americans share a recent common ancestor. These results greatly enhance our understanding of the peopling of Siberia and the Americas.
