Active Learning Approach in Simulated Health Guidance Utilizing ICT : Class Development and Improvement to Cultivate Practical Learning Instruction Abilities

　養護教諭の職務の重要な柱である保健指導の実践的指導力を育成するために，養成段階においても能動的学修を推進する必要がある。そこで教職科目「教育方法論」において，ICT を活用した能動的学修として模擬保健指導に取り組んだ。授業では，子どもの実態や健康課題に基づいて指導案を作成し保健指導の設計・実施・評価を一連の流れとしたグループ活動を展開した。平成25 年度から平成27 年度の3 年間の授業開発・改善の結果，「非常に到達目標を達成できた」とする学生は，平成25 年度の18.2%から平成27 年度は26.7%に増加した。「授業目標や内容が非常に理解できた」のは31.8%から60%，「教材が授業内容の理解や自宅学習に非常に役立った」のは40.9%から60%，2時間以上予習や課題にかける学生も18.2%から40%に増加した．保健指導の実践的指導力を育成し効果的な授業を可能とするためには，模擬保健指導をICT を活用した能動的学修にすることは有効といえる

Proanthocyanidin promotes free radical-scavenging activity in muscle tissues and plasma

金沢大学教育学部保健体育The present study was carried out to clarify the effect of oral administration of proanthocyanidin (PA) on radical-scavenging activity in muscle and plasma using electron spin resonance (ESR). Eight-week-old male Wistar rats were orally administered with 3 doses per day of 1 mL of 0.05% (PA0.05), 0.5% (PA0.5) or 5% (PA5) PA for 1 week. Control animals received the same volume of distilled water. We also examined the effect of a single dose of 0.5% PA. Blood and muscle were collected from rats 1 h after the final administration. Scavenging activity against superoxide anions in the plasma and m. soleus (Sol), m. plantaris (Pla), deep and surface areas of the m. gastrocnemius (GasD and GasS, respectively) and myocardium (Hrt) was determined using ESR with the spin trap, 5,5-dimethyl-1-pyrroline-N-oxide The scavenging activity in plasma for all groups given PA was 34%-44% higher than the control (p < 0.05). The scavenging activity in Hrt, Sol and GasD increased by up to 50% compared with the control and tended to increase depending on the dose of PA (p < 0.05). The impact of a single dose of PA was undetectable in all tissues. These results suggested that 1 week of oral PA improves the radical-scavenging activity in both plasma and muscle, especially in highly oxidative muscle. A single dose of PA was insufficient to improve the antioxidative capacity of muscle tissues. © 2007 NRC
