 หัวเรื่อง:การสำรวจแนวคิดเกี่ยวกับฟิสิกส์ของนิสิตนักศึกษาฝึกประสบการณ์วิชาชีพครูวิชาเอกวิทยาศาสตร์ทั่วไป ผู้เขียน: นายขจรศักดิ์ บัวระพันธ์, อาจารย์ , นางเพ็ญจันทร์ ซิงห์, รองศาสตราจารย์, ดร.วรรณทิพา รอดแรงค้า, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractTo explore the preservice science teachers' physics concepts and categorize those concepts with respect
to scientific concepts, 19 preservice science teachers from three teacher colleges were asked to complete the
Science Concept Test (SCT) consisted of physics, chemistry and biology content. In particular to physics
concepts, the results revealed that the preservice science teachers' concepts varied from scientific concepts,
alternative concepts, to incorrect concepts. Their scientific concepts arranged respectively from electric circuit,
electric current, to natural frequency of sound and their alternative concepts arranged respectively from
voltage, resistance, to work. Additionally, only one incorrect concept found was Newton's first law of motion
in case of at rest condition. |

หัวเรื่อง:การสำรวจแนวคิดเกี่ยวกับฟิสิกส์ของนักศึกษาฝึกประสบการณ์วิชาชีพครู ผู้เขียน: Khajornsak Buaraphan,, นางเพ็ญจันทร์ ซิงห์, รองศาสตราจารย์, ดร.วรรณทิพา รอดแรงค้า, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractTo explore the preservice physics teachers' physics concepts and categorize those concepts with respect
to scientific concepts, thirty three preservice physics teachers from seven teacher colleges all over Thailand
were asked to complete the Physics Concept Test (PCT). The test is consisted of the following main areas:
mechanics, wave, electric and magnetic fields, thermodynamics, electromagnetic wave, and atomic physics
and physics nuclear. The results revealed that the preservice physics teachers' concepts varied from scientific
concepts, alternative concepts, to incorrect concepts. From this, most of the preservice physics teachers had
alternative conceptions on all main areas. |

 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Histological Investigation of Fungal Endophytes in Healthy Tissues of Azadirachta indica A. Juss.) ผู้เขียน:V.C. Verma, S.K. Singh, R.N. Kharwar สื่อสิ่งพิมพ์:pdf AbstractThe presence of endophytic fungal mycelia within healthy tissue is most commonly detected by long incubation of small pieces of surface-sterilized healthy tissue on agar plates and the emergence of their mycelia or spores. Thus, to understand their biology and distribution within the host, it is mandatory to use histological tools to locate the endophytic mycelia as well as spores in vivo within healthy tissue. Thin microtome sections were stained with KOH-aniline blue procedures. The prominent fungal structures visualized were the fungal mycelia and occasionally spores. Mostly, the intercellular compact mycelia were observed with a few haustoria and clamp-like structures, while at several locations, the position was ambiguous. A few spore-like structures were also visible which were suspected to be the spores of Humicola or Nigrospora, since these genera have been reported as frequent endophytes from the same host (Azadirachta indica A. Juss.) by isolation methods. Some smaller hyphae were found under the cuticle and within the epidermal cells; however the larger hyphae were observed within all tissues including mesophylls, palisade and spongy parenchyma and vascular tissue. The study emphasized the localization, distribution and signifi cant presence of fungal endophytes of Azadirachta indica within healthy tissues, which may eliminate the suspicion with which some scientists view the presence of endophytes. The study provided further insight in the biology of the host-endophyte relationship as well as encouraging future investigations pertaining to host-endophyte interactions. |
