The paper should draw out the water and draw in the salt solution. 4. Observe the effects of the saline (salt) solution on the onion cells. Make a properly labeled, careful drawing of the cells appearance. ? 5. Replace the sodium chloride (NaCl) solution with distilled water in the same way that the salt solution was added. Make a properly labeled drawing of the cells ? ppearance in the space provided. Answer the following questions: 1. Draw a diagram to indicate the relative proportions of salt and water within the onion cells and outside the onion cells when they were placed in the saline (salt) solution.

Using Effective Instructional Strategies

Using Effective Instructional Strategies Instructional strategies include all approaches that a teacher may take to engage students in the learning process actively. These strategies drive a teachers instruction as they work to meet specific learning objectives and ensure that their students are equipped with the tools they need to be successful. Effective instructional strategies meet all learning styles and the developmental needs of all learners. Teachers must be equipped with a well-rounded arsenal of effective instructional strategies to maximize their effectiveness and to increase student learning opportunities. Teachers are best served when they utilize a variety of instructional strategies as opposed to one or two. Variety ensures that students are never bored. It also ensures that students will likely be exposed to strategies that align with their preferred individualized learning style. Students will enjoy being taught with a variety of instructional strategies and are likely to stay engaged longer. Ultimately, a teacher should align the instructional strategies they are using with the students they are serving and the content they are teaching. Not every instructional strategy will be the perfect fit for every situation, so teachers must become adept at evaluating which strategy will be the best fit. Effective Instructional Strategies Popular instructional strategies include cloze reading, cooperative learning, hands-on learning activities, scaffolding, group instruction, self-assessment, thematic instruction, and word walls. New instructional strategies are being developed and implemented in classrooms on an almost daily basis. Instructional strategies can also be completely customized, meaning that they can be tweaked and configured to fit any situation. Two teachers can be using the same instructional strategy completely differently based on their own individual preferences and needs. Teachers should put their own creative spin on these instructional strategies to make them their own. 5 Ways to Boost Student Learning Instructional strategies provide a delivery mechanism for presenting great content. Instructional strategies are the how, and content is the what. In many cases, how you present the content is more important than what you present. Students latch onto content that is packaged in an interesting and engaging way. A lack of a great delivery system will fail to make connections with even the most interesting content.Instructional strategies provide teachers with the flexibility necessary to meet individual learning needs.  The sheer number of instructional strategies at a teachers disposal provides the flexibility to differentiate instruction. What works well for one group of students may not necessarily work well with another. Teachers must adapt to each group and utilize multiple instructional strategies to maximize their effectiveness.Instructional strategies can make teaching and learning fun. The majority of students learn best through active, engaging learning opportunities. Many instructional strategies embrace this and feature components that ensure learning is fun and engaging. Teachers must make every effort to feature instructional strategies that keep students engaged, on their toes, and wanting more. Instructional strategies, when used correctly, keep students from becoming bored with how they learn. When a teacher uses the same strategy over and over again, it becomes boring to students. This is a great way to cause students to lose focus and lose interest in learning.  When a teacher varies activities, changes them up, and uses a wide range of instructional strategies students stay engaged. This ultimately helps them learn more.Instructional strategies enhance instruction and boost learning. When teachers are continuously exploring and tweaking their delivery system, a beautiful thing happens. Over time, they become more effective at not only finding great instructional strategies but also with implementing them into their class. Likewise, when students are exposed to a variety of instructional strategies it broadens the scope of how they learn - essentially giving them multiple ways to process and learn new information.

Marketing a consumer organization - Essay Example It began as an effort to help eleven Japanese-American children they had found wandering the streets of Japan as outcasts and orphans, victims of their bi-racial makeup, a cultural taboo. After successfully relocating these orphans, word spread and before they knew it they were instrumental in helping over one hundred such orphans find new homes and new lives. Between 1960 and 1964 they were directly involved in founding nine orphanages, a school as well as a hospital in both Japan and Vietnam. In 1974-75 the organization assisted thousands of orphans that were rescued during "Operation Baby Lift" and brought to the United States for adoption. In 1976 the organization changed its name to "Childrens Village USA." Then in 1978 the organization created a center called The Village of Childhelp West in Beaumont, California and officially became known as Childhelp (Childhelp 2007). The focus of the agency from that time is captured in its Mission Statement: "Childhelp ® exists to meet the physical, emotional, educational, and spiritual needs of abused, neglected and at-risk children. We focus our efforts on advocacy, prevention, treatment, and community outreach" (Childhelp 2007). They have several regional locations in Arizona, Atlanta, California, Michigan, North Carolina, San Diego, Tennessee, Virginia and the Washington DC Area. However their outreach and information and assistance programs transcend the traditional boundaries. Furthermore, their web site allows them to assist people in all parts of the world. Additionally, the Childhelp National Child Abuse Hotline (1-800-4-A-CHILD) which began in 1982 has received over two million calls since its inception: These calls come from children at risk for abuse, distressed parents seeking crisis intervention and concerned individuals who suspect that child abuse may be occurring. The Hotline is also a valuable resource for those who are mandated by law to report suspected abuse, such as school personnel,
