This website is organized around 75 genetics concepts. I love that it teaches students about each concept by using multiple types of materials (animations, pictures, videos, problems, etc.) and especially that it describes the ACTUAL RESEARCH conducted by a real-life scientist that gave us this knowledge. In other words, it has a focus on HOW we know what we know.

The Problem section in each concept is excellent. I will try to rework many of these as online quizzes for my class.

Personally, I think the apology for their role in the eugenics movement could be stronger.

This is a very useful tool to use for teaching Mendel and genetics. The site gives you a bunch of options where you can show videos and animations. For example, there is a video on Mendel where he shows how he cross pollinated two pea plants. The students can get a better understanding of the concept by just watching the animation and reading the captions.

There is a lot of information on this site, from reading materiasl to videos, animations, and supplementary links.  The information is clear and easy to understand. Just about any topic that you would want to cover in class concerning DNA and genetics is covered here, along with some extra interesting information. 

Technical Remarks:

The videos and the animations both played on the school computers, which isn't always the case.

I think this website is a great tool when it comes to introduicing the notion of genetics in middle or high school level. I particularly found interesting the various animations the use which is appropriate for middle school students. They also have practice problems for each concepts they introduce which is great to nail down the concept learned. As a teacher, this website will help me a lot in teaching Genetics and the notion of DNA which is sometime very abstract for younger kids to grasp.

This was an interesting collection of animations that will be very useful for their use in the classroom. It clearly explains the concept why DNA is an important macromolecule for all living systems, which clearly serves as an example of unity in diversity. DNA topics, an image gallery, video interviews, photographs, problems, biographies, and links related to DNA are exemplary. There are three sections, Classical Genetics, Molecules of Genetics and Organization of Genetic Material. Classical experiments are well explained.

I have not used this particular site, but have taught the classical genetics material in classes. If you cannot have students actively doing the studies with each other face-to-face, this is the next best thing! Individuals can interact intelligently with the material and it would be an excellent supplement to pairs or small group investigations. The problems require clear critical thinking.

The thing that I like most about the website, is that it is very simple looking and provides information in small chunks. I felt that as I went through the activities, questions that came up in my mind where answered on the next slide. In other words, it seemed really natural. I can see using this site as homework for students and for lesson plan ideas, I probably wouldn't use it during class though.

Technical Remarks:

It is a basic webpage. Does not require any installation of software, and is free.

I love this resource because it covers many different topics related to DNA. There is everything from Mendel's pea plants, to chromosomes, to the structure of DNA. I liked this aspect since it could be used in many different lessons on DNA or genes and will have specific information for the topic that is being studied. I also liked the information on the scientists that studied the particular aspect of DNA. It is a fun way to integrate the history of science into the curriculum. It would have been even more useful if some of the scientists had a little bit more information on them, instead of just their names and pictures. Some were explained in greater length, but not all. I didn't particularly like the organization of the site. I am happy and excited for the multitude of topics, but it was a little overwhelming as I was looking at the different topics. The topics were not organized in a usable way that teachers or students could easily locate the topic they want to learn about. It would be more useful if the topics were under subtopics of more general titles, so that the information that was needed could be more easily located. If a teacher were to use one of the pages for a lesson, they would have to look through all of the topics first to find the one that works best with the lesson. Once they found the right topic, it would be great for the student to explore, it would just be time consuming to actually locate that topic that would work with your lesson.

Technical Remarks:

I loved the animation that was used throughout the site. I think that it would keep students interested in the information and make the information more comprehensible. Any demonstrations like the ones on the site, help science come alive for students and give them a more concrete visual for science procedures and concepts. This type of resource would be especially useful for visual learners.

This a great resource. There are tons of visuals and animations that can be very beneficial to students. It is broken up into three sections: Classical Genetics, Molecules of Genetics, and Genetic Organization. Within each section there are 10-15 subsections that all include Concepts, Animation, Gallery/Images, Audio/Video, Bio, and Problems. This resource thoroughly explains concepts and provides great visuals for students.

I spent about a half an hour reviewing the DNA from the beginnings presentation tool. I found it to be interesting yet informative. I thought the content was well presented in a fashion which made it easier to learn. This tool used animation, video, and sound to create a learning environment which is conducive to all learning styles. The site ran quickly and smoothly and without error. I would recommend to anyone trying to give a visual representation of DNA to a high school class.

Technical Remarks:

This tool was extremely easy to navigate through. It would be ok for a beginner/novice to use the tool in the classroom setting.

I’ve always been interested in genetics and this website is a fun way to review and learn new things related to that topic. The animations and problems are great interactive devices to allow one to think about what is being presented. The audio visual interviews presented many facts in a way that is more interesting and fun than just reading.

I am a fourth year college student. I was instructed by my college professor to
join merlot and to review three websites and pick my favorite. This was my

I feel this website was of the highest quality. It provided a vast array of
information in an enjoyable manner. The webpages were setup in such a way that
you don't realize how much you are learning until you have completed the
"lesson". I am currently taking a genetics course at South Dakota State
University, and we have or are currently covering many of these topics. I found
it much more effective to "view" the experiments rather than merely hear about
them. The videos and sound were excellent and I appreciated the animation
allowing me to move at my own pace. I was not forced to move through too
quickly, or drug along for a long ride.

I believe this site would be beneficial to any student who learns well by seeing
and hearing the topic in pictures and sound simultaneously.

I found this site to be extremely easy to navigate. The side menu options are
always the best way to go. I appreciated being able to select the next topic
quickly. I also thought the tabs on the bottom of the page which allowed the
selection of different functions without using the "back" button were efficient.

I reviewed this site for about an hour initially, then returned to it to plan
how to use it in my general biology classes. I plan to use it in March.

Quality of Content: Comprehensive, accurate
information from classical genetics to today?s advances in molecular genetics.
The credibility of the source, the DNA Learning Lab at Cold Spring Harbor Lab,
insures that learner that the information is ?first hand? and accurate. Much of
the content is presented by the actual researchers (primary sources) and
reflects the
realism of day-to-day lab research conducted by real people. Wonderful
historical reflection on DNA research as well as today?s progress.

Potential Effectiveness as a Teaching-Learning Tool:
This source addresses a variety of leaning styles by using tutorials,
explanation of terms, audio/visual,animations, and interaction during the
problem phase. The links are helpful to instructors and/or serve as a
springboard for student reflections or projects on the
topic. The information is presented in ways that are relevant to learners and
the problem-solving approach helps learners advance to a higher level of
learning and reasoning. This approach leads to more meaningful learning than
just memorization. The lessons teach for
understanding. These activities also expose learners to real science and the
people who have contributed to our knowledge of DNA. They show that science is
a means of
problem solving that can be applied to other contexts.
An index of content could be helpful, especially for students who are unfamiliar
with the content. If it ould be more interactive (not just tutorial) the
learners could be more involved.

Ease of Use: No problems here. It was very well organized and the format was
consistent. Learners can focus on the content and not be bogged down with
navigation issues.

I use this site when teaching a sophomore core course in cell and molecular
biology. The tutorials and assignments that animate classical experiments, such
as the Griffith transformation, Hershey & Chase and the Meselson & Stahl
experiments are excellent. Using them in a classroom setting allowed me to
cover the material in one half the ususal time, and allowed me to ask more
thought provoking questions on the exam. Students seemed to comprehend the
experimental designs faster and better, and commented very positively on the
supplemental use of this site.
