Education Technology and Me
Educational technology can be described as any technological tool that aids in the
explanation and understanding of information. A major benefit to these tools is that teachers
can use them to better present information to their class in many ways that they could not
before. Whether it is to help explain a complex topic or just add another dimension to the
lesson, technological tools can help teachers present the information to students visually,
audibly, kinesthetically, or in many other ways that help them to better understand the lessons.
In a high school algebra or geometry course, a teacher can utilize the software Geometer’s
Sketchpad to help the students visualize concepts they are learning. With software like this,
students would be able to create figures and interact with them in a way that helps them to
better understand topics like transformations, congruency, area, ratios, tangency, and many
more. Rather than spend time drawing images by hand or working out simple computations,
classes can use technology to quicken their work so that they are able to focus more on main
concepts they are learning. While technology can be very beneficial to a classroom, it is up to
the instructor to judge the appropriateness of the piece of technology for the class. Not all
technology will be helpful to a course and those that are will not be used every day. It is up to
the teacher to assess the value of the different technological tools at their disposal and
determine when they are appropriate for use. They must see that the tools will in fact help the
students’ understanding and be worth the time to use.
My personal experience with educational technology is minimal but developing. Having
taken the course Math 305, I have gained both a better understanding for the importance of
technology in the classroom, as well as some situations it can be used. However, I am still
![Page 4: Right Triangle Trigonometry Portfolio Kyle Linford Eastern ... · determine when they are appropriate for use. They must see that the tools will in fact help the students understanding](https://reader033.vdocuments.us/reader033/viewer/2022060522/6051db922444975acb453073/html5/thumbnails/4.jpg)

actively seeking to improve my understanding of the many ways it can be used and their
appropriateness. During my time in Math 305, the class had a discussion about the appropriate
use of calculators in the classroom. While many people found calculators to be a crutch for
students, the teacher questioned this view by having the class think about what they consider
important for students to be able to do. She asked if always being able to remember what
certain products of numbers are should be the main focus of a math class. The situation she
gave suggested that if we had a student who had difficulty remembering multiplication, should
we really worry since there are many pieces of technology that can do the computation for
them, or should we focus more on making sure they understand the concept of multiplication
and its application? This questioning of the traditional view of education caused me to examine
the importance of technology in a new way and the ways it can be implemented in a class.
Though I am still learning when it is appropriate, I can value the use of educational technology
in a class and begin to supplement technology that I find is helpful and beneficial to future
classes.

ISTE Standards
1. Facilitate and Inspire Student Learning and Creativity—Teachers use their knowledge
of subject matter, teaching and learning, and technology to facilitate experiences that
advance student learning, creativity, and innovation in both face-to-face and virtual
environments.
Summaries of Standard Meeting Technology
a. Core Math Tools: Core Math Tools is an online office suite that provides users
with a collection of free mathematical programs. These programs include a
computer algebra system, a dynamic geometry environment, a simulation
runner, and many other features that are beneficial for a math class. These
programs provide users with a collection of abilities that replace other, more
expensive programs like Microsoft Excel, Geometers Sketchpad, or the TI-Nspire
CAS. Because of these free capabilities, this program is one that would be
beneficial to incorporate into any classroom. While a math classroom will
receive the full benefits of this suite, classes in other subjects who are unable to
use expensive programs designated for the math classes can download Core
Math Tools for free and utilize its many features. Whether it is exploring
geometry with the interactive whiteboard, running advanced simulations, or
working through the calculation functions, Core Math Tools is a suite that
provides helpful and necessary math features to any possible classroom.
b. Fakebook: Fakebook is a website that allows users to create parody Facebook
pages of historical figures and well known celebrities. While it can be seen as a

They must see that the tools will in fact help the students understanding](https://reader033.vdocuments.us/reader033/viewer/2022060522/6051db922444975acb453073/html5/thumbnails/6.jpg)
Linford 6
comedic endeavor, Fakebook can be used by classrooms to promote thinking
that is of high cognitive complexity values. Instructors can use this feature to
engage students understanding of a specific topic to analyze, interpret, and
create a Fakebook page. For example, an English instructor can assign students
to create a Fakebook for some literary character. Students will need to truly
understand the literature they are studying to create the persona of their
character online. Similarly, a history class can utilize their understanding of
historical events to create an account for a historical figure.
c. TI Nspire: As a mathematical tool, the TI Nspire provides users with the benefits
of both a graphing calculator as well as a computer algebra system. For a class,
students would be able to perform all of their calculations on the Nspire, while
also working through the benefits of the CAS. They will be able to create and
save files for their work, explore dynamic geometry environments, and many
other interactive features. Some of these features are available online for
download from the Texas Instrument website. These features include
preprogrammed features for instructors to use for their students. As a teacher,
one can have students work through these preprogramed downloads and
interact with the different visual features they provide. The benefits of this tool
become incredibly beneficial to helping to better achieving the desired learning
goals.
2. Design and Develop Digital-Age Learning Experiences and Assessments—Teachers
design, develop, and evaluate authentic learning experiences and assessments

incorporating contemporary tools and resources to maximize content learning in
context and to develop the knowledge, skills, and attitudes identified in the NETS•S
Summaries of Standard Meeting Technology
a. Movenote: Presentations and lectures are important to lessons. Especially with
online learning experiences, they provide students with necessary information in
an abbreviated and organized way. However, posting them online for students
to read can become confusing and uninformative without a narrative. By
utilizing Movenote, instructors can provide narrative commentary for their
presentations to provide students with both a visual breakdown of the lecture,
as well as an auditory explanation. This interactive program can allow
instructors to record their auditory lecture over different slides and interact with
the slides through the use of a laser tool. When having to incorporate a lesson
into an online environment, this tool will be extremely helpful to ensure the
necessary information is presented to the students in way that fits the desired
learning goals. Rather than link students to external videos or simply post slides
to a lecture, the instructor can provide an explanation that fits their class’s
needs.
b. Skitch: Skitch is a tool from Evernote that allows users to interact and mark up
images. Similar to the benefits of Movenote, Skitch provides instructors with a
way to interact with images that are important to helping students understand
the desired learning outcomes. From this interaction, teachers can highlight key
information for students and provide commentary along with it. Students in a

math class might find this particularly helpful when their instructor can interact
with and explain the components of a mathematical concept being visually
represented.
3. Model Digital-Age Work and Learning—Teachers exhibit knowledge, skills, and work
processes representative of an innovative professional in a global and digital society.
4. Promote and Model Digital Citizenship and Responsibility—Teachers understand local
and global societal issues and responsibilities in an evolving digital culture and exhibit
legal and ethical behavior in their professional practices.
5. Engage in Professional Growth and Leadership—Teachers continuously improve their
professional practice, model lifelong learning, and exhibit leadership in their school and
professional community by promoting and demonstrating the effective use of digital
tools and resources.
a. Organizations like Edutopia and ISTE help teachers meet this standard by
providing them with resources and information to better improve their ability to
understand and integrate technology into the classroom.

Components of an Effective PowerPoint
There is a reason that PowerPoint causes people to cringe. Many individuals have had
horrible experiences either making or being forced to watch poorly made slideshows. These
presentations are often lackluster, hard to follow, and mind numbing. However, if they were to
be adjusted by following several techniques for PowerPoints, these slideshows would become
far more powerful for an audience.
The first tip labeled is one that, in my experience, has been the biggest problem with
presentations: “Simplify and limit the number of words on each screen.” If someone is
unprepared for or unsure about their presentation, they will cram an excessive amount of
information onto a slide. This provides the viewer with too much information to read and pulls
their attention away from the presenter. During one of my education courses at Washtenaw
Community College, my instructor would constantly load the screen with paragraphs of text. As
viewers, we were unable to focus on what she was saying as we tried to read and copy the key
information from the slide. These slides were so wordy that she was unable to do anything but
read right off the screen. This inability to talk directly to the audience presents another issue
people have with PowerPoint.
People often set PowerPoints up as if the screen is their notecard. They read from the
slide and speak to it. These two issues are listed specifically as “Do not read from your slides,”
and “Do not speak to your slides.” This causes the audience to become unfocused on what the
message is because the speaker is not speaking to them. During a group presentation, a
partner I had been working with spoke in this way. Their actions reflected to the audience
someone who was unprepared and disinterested in what they were saying. Soon the audience

lost interest in us and were unfocused on the turned around speaker. No matter how well the
slides are prepared, the speaker loses the audience by their inability to properly communicate
what they intend.
To further explore the things that can cause an audience to lose focus on a presentation,
the disorienting and distracting effects of flashy transitions is discouraged. The tip suggests for
presenters to “avoid the use of flashy transitions.” In my experience with good presentations,
the speaker always kept their transitions and animations consistent and minimal. This kept the
focus on the speaker and the message they are conveying. By utilizing this and other
techniques, a person can better develop a presentation that resonates with the listeners and
conveys the message needed to be understood.

Technology Integration
My Definition:
Technology integration is the incorporation of technological tools into classrooms for student
learning.
Edutopia Video:
In the video Technology Empowers Student Fieldwork, the use of technology was integrated
into the classroom as a tool to help further student understanding with a class project. For this
project, students and local farmers worked together to track horny toad lizards with the
NatureMapping program, as well as GPS trackers. This equipment allowed the students to be
able to better track where the animals were located and how they can monitor them and the
environment. The director of the task mentioned how she finds that the project-based task is
able to bring science, math, technology, and even art to the students in a way that provides
them with real world applications. From using these sophisticated technologies, students
appeared to be more engaged in the information they were learning, the differentiated tasks
allowed them to work in a variety of ways, and their ideas can be exchanged with other schools
across the country.
Level of Integration:
Based on the information from the videos, the classroom appears to be at the appropriation
level of integration. Here, the students are working collaboratively with their classmates and
local farmers to better understand and track the horny toad lizard. They are sharing their
research on the Internet and working together to achieve a goal.

Reflection on Web Development
The ability to develop original web content is a skill that teachers can benefit from as
professionals and educators.
As a professional seeking employment, the ability to develop a personal website is very
important. It signifies that one is knowledgeable about technology, and it presents their
professional resume to potential employers. Now, administrators are able to not only access a
person’s resume and see their skill sets, but also, they can have direct links to projects and work
the person has created. This technological skill set helps to further show one’s ability to create
original web content for students.
By creating an original WebQuest, I was personally able to use my technological skills to
develop an engaging online experience for students to practice both their conceptual
knowledge of trigonometry and online research. The task for the students is one that forces
them to use their knowledge of trigonometric identities to create a rainwater irrigation system.
By using math to solve a real world application problem, students are able to have a better
understanding of the trigonometric identities they are using and how they can be implemented
to solve problems. However, by asking students to question their responsibility and
involvement with their local communities, they are able to further build on their
understandings of larger concepts, like community and the environment. From creating simple
projects like a WebQuest or a person webpage, teachers are more able to better demonstrate
their abilities as a professional and educator.

Plagiarism
There is more to writing a paper than cutting and pasting information. Plagiarism is a
serious ethical issue that educators are facing. Often, students will submit an assignment as
their own even though it is someone else’s work. However, a student’s desire to cheat is not
always to blame for a situation like this. Sometimes, an individual’s ignorance about plagiarism
can cause the incident to occur. To help lessen the occurrence of this issue, strong, clear
information about plagiarism should be discussed openly with students in a classroom.
Though there are cases were the act of plagiarism was knowingly committed by a
student, some situations reflect more of the student’s ignorance about the issue. According to
a survey by the ATL, they suggest that most students “don’t know the difference between
plagiarism and legitimate research” (rpt. in Clay). Teachers need to understand that students
caught plagiarizing may be unaware why their actions are considered wrong and unethical.
Self-reflection will be needed in this situation to properly judge whether the topic of plagiarism
was properly covered in the class and if the student is responsible for their actions. According
to Chris Harrick of Turnitin.com,
“The big challenge that educators have is to make sure that they teach their
students the proper way to find material on the web, how to document it,
what’s acceptable and what’s not, and then use tools to make sure that those
protocols are followed” (qtd. in Zwang 9).
Working at the Washtenaw Community College writing center, I have had to help many
students understand the concept of proper citations. It appears that about half of the students
I work with are unaware of how to properly cite information in MLA or APA format and are

unsure about what information they can consider original. Teachers need to discuss this ethical
issue in their classroom to help ensure that students understand both the technical and ethical
aspects of the matter. In this way, students will be able to better find research and understand
when to cite it in their work.

Reaching Out with Digital Age Media
By using media like newsletters and blogs to reach out to parents, teachers are better
able to fulfill the ISTE standard that requires the effective communication of relevant
information and ideas to students, parents, and peers through the use of digital age media and
formats. This communication allows teachers to present this information in a professional and
organized way that all parents are able to access. Teachers can first think about what they
want to convey to the parents and organize it in a way that is easier to comprehend. Parents
are then able to learn important information from their child’s instructor in a clear and concise
way.
Further, this information can become easily accessible. By creating a blog or emailing a
newsletter, teachers can be in quick communication with all parents. Anyone with computer
access can read the teacher’s messages and respond appropriately. However, teachers will still
need to take the technological divide into consideration and make appropriate
accommodations.

Online Teaching
With the ever growing development of technology and forms of communication,
education has new ways to differentiate and progress.
Because of modern technological advancements, education can reach past the
classroom walls. Technological tools, like Moodle, Weebly, live chats, videos, and blogs, allow
teachers to present their lessons to students at any time and location; they are not confined to
just the hour long sessions in their classrooms. This online teaching creates individual
opportunities for students to learn at a speed that suits them. Students are able to work
individually and focus on the material in an environment that suits their preference. However,
though the students can work individually on the activities and lessons, they do not have to
work from this on their own.
A main aspect of the technological advancement is the progress in communication.
Teachers and students have access to different ways of communicating outside of the
classroom. Students are now able to live chat with their instructors, make Skype calls, and
interact with their teacher and the academic lesson more often. Other than just the individual
student and teacher communication, whole classes can interact online to discuss the lesson and
information they are working from in the class. Both individual and cooperative learning can be
branched out from the classroom lesson.

Moodle Organization
Title:
Right Triangle Trigonometry
Introduction:
To introduce the students to the online lesson, I will begin by introducing myself as their
instructor. Included are my name, contact information, and a link to my professional website.
Additionally, students will find a list of standards that will be used in the lesson and several
external links to extra information about trigonometry.
Anticipatory Set:
This lesson will proceed with the assumption that students are unaware of the trigonometric
relationships involved with right triangles. To help introduce them to these relationships, or
review them for those who already are knowledgeable, a short video will be used that explains
these relationships in depth. In the video, I will explore what a right triangle and its
components are; angle measures, including degrees and radians; the trigonometric identities of
sine, cosine, tangent, cosecant, secant, and cotangent; the inverse relationships; and some
application problems.
Guided Practice:
As the students begin to understand the large concepts of right triangle trigonometry, they will
begin to practice their knowledge through a series of problems in a Microsoft Word document
to help in their understanding of the topic. These problems will walk students through the
necessary steps and build in complexity. As they work, students will be able to contact me and
schedule quick discussions to help answer any questions they might have about a problem.

Linford 20
Independent Practice:
Having gained a sufficient knowledge about the topic of right triangle trigonometry, the
students will be challenged to demonstrate their understanding by completing the inquiry-
based application WebQuest I created. In this activity, students will put their understanding of
right triangles to use in creating a rainwater irrigation system for their school’s community
garden. By working from this web formative assessment, students will be exposed to a better
understanding of both the applications and concepts of right triangles as they strengthen their
computation skills. This WebQuest will be linked to the Moodle page along with a description
of what students are expected to do for the activity.

Visualization in the Classroom
Visualization is an important factor for the improvement of one’s education. It allows
students to better interpret and understand concepts and topics being discussed. Visualization
in the classroom can be implemented through the use of software like Inspiration or the
webpage creator, Weebly. The Inspiration software allows for users to organize creations in a
way that help themselves and others to visualize the different aspects being covered. Teachers
can use this for their own explanations of concepts to a class. As an instructor attempting to
breakdown the topics for a particular lesson, one can utilize the Inspiration capabilities to
create a visual organizer for the students to better understand the content. Similarly,
instructors can also use the webpage creator Weebly to further help organize and develop their
lessons in a larger way. Rather than focusing of the breakdown of a specific topic, Weebly
pages allow for users to create sites that can be broken down into different sections and
presented in a way that engages the students. Additionally, students can work through
creating these diagrams to explore their own understanding. For example, students beginning
to write essays can create organized outlines and clusters from this software in a way that
provides more options than just writing it out traditionally. From these connections, the
visualization and organizational aspects of programs like Inspiration and Weebly can be seen to
better improve the understanding of students.

Moodle Reflection
The Moodle page I created is the page Right Triangle Trigonometry. The main focus for
this lesson was to explore the trigonometric identities through the components of a right
triangle, as well as solving for these specific components with given information. While
students work through these specific topics, they will gain a better understanding of the specific
concepts being explored by seeing how mathematics can be applied to the development of
their communities. To accomplish these learning outcomes, the Moodle features a collection of
materials, including quizzes, embedded videos, downloadable files, and a WebQuest activity.
From these different features on the Moodle pages, students will be better able to explore the
topics being discussed in an organized and engaging way. The students will begin with an
introductory, diagnostic assessment that gauges their entry understanding of topics that will be
taught. They will then watch a series of videos that provided detailed information about the
identities being learned and their applications. These videos were found to provide very helpful
explanations of not only what the identities are, but the reasoning behind their development as
well. By exploring these detailed explanations of these videos, students will find themselves
more confident in their understanding of the topic and its applications to community. The
students can then practice this understanding through the downloadable homework and
demonstrate their potential mastery of the topic on the final quiz and WebQuest activity. The
WebQuest was created as an inquiry based project that required the students to demonstrate
their full understanding of the topic and apply it to their exploration of a community problem.
In this way, students can follow an ecojustice education framework to explore the subject’s
