The most useful forms of technology that I used in Math Methods were the basic communication tools - Google Docs and email. Working with large groups of people, it would have been a nightmare to prepare our projects without Google Docs. There was a number of times when several of us were editing the Google Docs at once - something we could not do with the Wiki. We also used email and chat extensively to communicate about meeting times and questions regarding our projects. These two tools - Google Docs and email - were life-savers for this class.
Other technology sources that we used included the wiki page, smart board, Geometer's Sketchpad, calculators, Sakai forums, and NCTM resources. The wiki page was frustrating because only one person could edit at a time. Therefore, if one person had three or four hours of information to add to the wiki, the other group members were handicapped for that period of time unless they stole the lock from the other person. If they chose to steal the lock, the other person's information would be lost. Google Docs was far superior to the wiki. The smart board is a tool that I have already used in Novice Teaching, and I presume that I will be using it in my future occupation. I appreciated the opportunities in Math Methods to play around with smart board. Geometer's Sketchpad is an excellent tool for helping students grasp geometry concepts without having to create their own representations by hand. Learning about this tool was very beneficial, and I can see myself using it in my own classroom some day. The calculators that could figure fractions are a long-time awaited invention. Now students will be able to discover math instead of simply doing math, by experimenting with LCM, GCF, adding, subtracting, multiplying, and dividing fractions, and other information regarding fractions. The Sakai forums were a useful tool for claiming our articles, although it would have been just as easy to send and email to relate that information. Finally, the NCTM website was great, with its vast resources including applets and illuminations. I am excited to know of such a rich resource where I can find activities to supplement or teach math concepts.
Overall, the use of technology in Math Methods had given me tools to fulfill the following quote: "The art of teaching is the art of assisting discovery." I look forward to using technology in the future as a means to "assist discovery" in my students.

Supporting Language Learners
Supporting Language Learners from Teaching Children Mathematics
This article suggests two methods of assisting language learners in the mathematics classroom. One method involves helping the students through their English language acquisition. Some strategies include using advanced organizers, bi-lingual organizers, explaining mathematical terms as homonyms (some,sum), visual cues, and adjusting teacher talk (repeating, slowing down, simplifying, consistency, and avoiding idioms). The article discussed two tasks which assist language learners in developing their terminology. One involved a story with manipulatives relating to the story (fishing) and checked the students' understanding of "more than" and "less than." The other activity shows how teachers can change the wording of directions to a problem to be more consistent with language learners vocabulary. A second method of helping language learners in the classroom is to promote a low-anxiety classroom environment. Teachers should reassure the language learner that mistakes are common. They should teach their students how to applaud and praise each other rather than ridicule mistakes. Routines also help language learners feel comfortable in the classroom - knowing what will come next in the day. Finally, teachers should use signals and assign classroom buddies to ease tension that language learners may feel .
I have already had the opportunity to apply some of these strategies - not with language learners, but with a student with Asperger's syndrome who struggled processing words and dictating his thoughts. I noticed that assisting him with understanding words was always necessary, regardless of the subject. He was an intelligent child, but simply needed extra help with vocabulary. I also noticed that he performed much higher when he was at ease in the classroom. If he felt like his peers were watching him or making fun of him, he lost all ability to function. I am sure that language learners will pose different experiences than I had with this student, but I do believe that applying the strategies for making the classroom a comfortable place and helping them with their vocabulary will assist them greatly in mathematics.

Making Technology Work
Making Technology Work from Mathematics Teaching in the Middle School
This article encourages teachers to ensure that their use of technology follows this criteria: it allows students to do something they could not have done before, or it allows students to do something they could do before in a better way. It warns against using technology when students could perform a task more quickly without the technology; yet it promotes using technology to help students use higher-level thinking and to visualize math better. The article provides an example of a beneficial use of technology - The Weather Project. In this project, the students must create a pamphlet about the weather in five different regions of Croatia. The project not only connects to other subject areas, it allows students to work with real data and to use technology to interpret and represent the data. The students took ownership in the project because it was a real to life experience.
I appreciated that this article addressed the need to use technology wisely. Technology can be powerful, but it can also be debilitating if it does not meet the criteria for beneficial uses of technology. If I take anything from the article, it will be to ask myself as a future teacher whether my desire to use technology truly allows students to do something they would not be able to do otherwise. Does the technology promote higher-level thinking? Will it enable students to engage in real-world applications of mathematics? Will it engage students in exploration and discovery? Technology cannot replace the brain - and teachers must be careful that they use it in a way that enhances learning.

Assessing Understanding Through Reasoning Books
Sally K. Roberts and Carla Tayeh
March 2010, Volume 15, Issue 7, Page 406
http://www.nctm.org/eresources/view_media.asp?article_id=9178
In this article, teacher candidates are challenged to make a booklet of reasoning and proof which show that they know how to communicate mathematical concepts and ideas to a larger audience. Their instructors do not allow them to say, "You know what I mean" even if it is obvious that they do know what the student means. It is important for teacher candidates to be able to understand a problem at a deeper level than by simply giving the correct answer. Later in the article, middle school students were challenged to use reasoning and proof to solve a problem without a clear-cut answer. Some of the students found an incorrect answer using faulty reasoning. Some of the students came up with the correct answer using good reasoning, but without providing adequate defense or proof to show how they found the answer. Finally, some of the students used good reasoning and proof to find and convey their answers to a wide audience.
I think that reasoning and proof can be the most challenging, yet important, component in mathematics. Because communicating our reasoning takes time and practice, teachers should begin to help students communicate their thoughts at a young age. I hope that I can resist the temptation to nod at a student and say, "Yep. You have the right idea. I know what you are trying to say. Good job." Students need to be given time to sort through their reasoning - to justify their thinking. This is perhaps as important as coming up with the correct answer.

Sand and Water Table Play
Teaching Children Mathematics
March 2010, Volume 16, Issue 7, Page 394
In this article, the teacher emphasizes the value of play in mathematical learning of young children. Children left alone to play may not develop mathematically, but children playing with a teacher in close proximity prompting them to think while playing offers great possibilities. This teacher kept a table in her kindergarten classroom filled with sand. She placed geometric containers, beakers, and bottles in the sandbox. At first, the students were allowed to play and the teacher simply observed the students' discourses and mathematical play, and considered possible math interventions that would naturally flow from the students' play. Then, the teacher played with the students. She asked only a few simple questions to enrich their play - to get them thinking about their play. Finally, when she noticed a frustration with some mathematical concept within the students' playing, she developed lessons from those frustrations to meet the state standards for kindergarten mathematics.
I am always in favor of hands-on learning, as long as the play truly causes learning and is not simply play. This article provided a good example of how to use play to interest the children and to make their learning relevent to them. I think that I will attempt to use such student-centered learning in my future classroom of (hopefully) intermediate or middle school students. I may not provide as much time for free-play with older grades, but I hope to allow a measure of freedom so that I can learn the subjects that matter most to my students, thereby creating lesson that they can relate to.

Portfolio Assessment
Damiani, V.B. (2004). Portfolio assessment in the classroom. In Helping Children at Home and School II: Handouts for Families and Educators (S3, 129-131). Retrieved from http://www.nasponline.org/communications/spawareness/portfolioassess.pdf
Using portfolios is an authentic method for assessing student work, from primary grades through college levels. A well-done portfolio contains a collection of student work from a specific topic or theme. Portfolios are valuable in that they show what students can do - not just what they know.
The portfolio process involves several steps:
1. Decide on a purpose or theme for the portfolio
2. Consider what samples of student work might best illustrate the goal being assessed.
3. Determine how samples will be selected.
4. Decide whether to assess both the process and the product, or just the product.
5. Develop an appropriate scoring system.
6. Share the scoring system with the students.
7. Engage the student in discussion about the product.
Portfolio assessment has several advantages and challenges.
Advantages -
1. Assesses what students can do - not just what they know.
2. Engages students actively
3. Fosters student-teacher communication
4. Fosters depth of exploration and learning
5. Helps parents understand the educational process
6. Provides goals for student learning
7. Offers an alternative to traditional testing
Challenges -
1. Establishing scoring systems that are reliable over time and with different raters
2. The process is time consuming.
3. Portfolios portray depth of student learning, but not breadth - assessment is over a narrow theme.
4. Keeping the process fair, when some students may have advantages in their homes, such as parental support and access to technology.
5. It is difficult to compare the students' learning to students across the nation.
6. Students may not accurately self-assess their work if they know it is being assessed by the teacher.

Video analysis - graphing
The purpose of the activities in this video is for students to represent graphs in a variety of ways and to extract meaning from the graphs. The students first create a story about the graph, which helps them learn that the graphs depict a relationship between two quantities. Next they create tables as another representation of the graph, and finally they develop an equation to show a fourth representation. The content of the graph is therefore shown as a graph, a table, a story, and an equation – four representations!
Lesson Analysis 1: Describe the primary task in this lesson and identify the mathematical skills and concepts that this task is designed to develop.
The primary task in this lesson is for students to create a sequence for their classmates and teachers to figure out missing numbers. In order to meet that goal, students will develop the skill of representing a concept in several different ways and problem solving to find a generalized equation for that sequence.
Reflective Task 1: Describe how appropriate you think the primary task in this lesson is for developing an understanding of the mathematics being taught.
I think the primary task in this lesson was very appropriate because the students had to use various representations to display the meaning of the graph, communicate mathematically in groups, and problem solve to figure out a sequence that would be a challenge even for their teacher. Not only were the process skills used, but the students developed a better understanding of the relationship between two variables in a graph because they attached personal meaning to their graphs through stories.
Lesson Analysis 2: Describe what the teacher does to support learning while students are working in groups.
The teacher supports learning by asking guiding questions to assist the students’ thought processes. She did not simply tell them the answers or tell them how to think, she guided their learning through questions. She also encouraged the students to communicate mathematically with each other, telling them to “talk about it in your groups.” As she rotated between groups, she listened to their thinking patterns to understand where they were misinterpreting or forgetting some important aspect of their problem.
Once again, I benefited from watching the videos because I could actually see the teacher leading the children to understanding. It is helpful to witness someone carrying out the strategies we learn in school. Observing her decisions motivated me to one day guide students to learning through the process standards rather than teach them the way I was taught.
