Abstrak: As far back as the late 1800s, U.S. physics teachers expressed many of the same ideas about physics education reform that are advocated today. However, several popular reform efforts eventually failed to have wide impact, despite strong and enthusiastic support within the physics education community. Broad-scale implementation of improved instructional models today may be just as elusive as it has been in the past, and for similar reasons. Although excellent instructional models exist and have been available for decades, effective and scalable plans for transforming practice on a national basis have yet to be developed and implemented. Present-day teachers, education researchers, and policy makers can find much to learn from past efforts, both in their successes and their failures. To this end, we present a brief outline of some key ideas in U.S. physics education during the past 130 years. We address three core questions that are prominent in the literature: (a) Why and how should physics be taught? (b) What physics should be taught? (c) To whom should physics be taught? Related issues include the role of the laboratory and attempts to make physics relevant to everyday life. We provide here only a brief summary of the issues and debates found in primary-source literature; an extensive collection of historical resources on physics education is available at https://sites.google.com/site/physicseducationhistory/home.

Abstrak: This research aims to investigate the role of government buy-local campaign to increase consumer willingness to purchase local products in Indonesia. This paper also aims to identify relevant mediating variables between exposure to “buy local” campaign and willingness to purchase local products. This research use questionnaire data from 394 respondents selected using purposive sampling method. Product specific constructs are asked and analyzed separately in four different product categories (e.g. Produce, Leather, Culinary and Creative products). Data was analyzed using Structural Equation Model and compared further between product categories. The study found that exposure to the buy local promotion campaign does increase consumer ethnocentrism, attitude toward the campaign and toward domestic products. Consumer ethnocentrism does increase attitude toward domestic product and willingness to purchase local products.

Abstrak: Udang galh betina menghasilkan 10.000-20.000 telur tiap memijah. Setelah menetas, ``sekitar 25-50% berkelamin betina,`` ujar Dr Fauzan Ali, peneliti di Pusat Penelitian Limnologi Lembaga Ilmu Pengetahuan Indonesia (Puslit Limnologi LIPI), Cibinong, Bogor. Itu berdasarkan pengalamannya 3 tahun meneliti Macrobrachium rosenbergii. Sekarang, udang galh bisa menghasilkan 100% jantan.
