It says that children can learn with internet without any intervention from outside -like a teacher. When the topic is not defined, children can learn what they want. But for some specific topics, they at least need the very first idea -a question, sometimes even a pre-designed system of information and instruction. Are we too much interfering to students' learning process?

Such educational frameworks support the trend of shift from teacher-centeredness to student-centeredness. In the past, when we need to ask something, we asked to our elders- in school, to teachers. Now, we have an additional elder, the internet. It can answer almost anything. In that sense, the impact of the technology can not be ignored. The idea of providing internet access to places that is scarce in terms of teachers is reasonable - which also supports the idea of distance education. Besides, bringing technology is easier and cheaper than bringing a teacher with resources. However, we still need teachers as -cliche but vital term- "facilitators" and regulators in self-learning process. It is necessary for constructivism as well as child-driven education or for any other self-learning methods. Someone is needed for wrapping-up the knowledge gained, for assessing the results, for remedying circumstances that obstruct the learning process, for deciding goals or organizing goals to be attained, and for secure and heuristic browsing on the internet. In that sense, I support the idea of "self organized learning environments" as Mitra offers, but also I contend that there should be teachers around these environments for facilitating. In short, we should not quit important elements of education while trying to make it better.

I believe although computers and instructional softwares are amazing to enhance the effectiveness of instruction, they are not enough. They are always limited. It is impossible to load them all possible questions of students and their responses. Moreover, none of the computers or softwares would be able to fulfill students' emotional and motivational needs. There is also the uniqueness of the students; not all of the students would enjoy a computer-based education. Lastly, as a science educator when I think for my area; it is never the same to make an experiment on computer and in a laboratory. Students learn better when they are actively engaged in an experiment and seethe results with their eyes.

Recently I came across with this paper. According to authors Learning Science has at least 4 dimensions: Education, Neuroscience, Psychology and Machine Learning. By the way, just a fresh news: Next semester we may have a "Learning Science" course offered by Evrim Hoca ;)

Dincer, thanks a lot. I will definitely check this out.

A book on science of learning from the cognitive psychologist: Gary Marcus

I believe that this lesson plan is a very good example of a constructivist lesson plan for a science lesson. It has many steps that involve the student actively. And as I read I felt that the student is not only hands on, but minds on also. What I mean is that it is clearly a process-oriented plan. Even if the student can't do well in some steps, there are other activities that he can accomplish and enjoy. Also the stress on group work is evident, student can learn from each other and take responsibility. Evaluation part is also very clear, explained to the students with a rubric and it relies on presentations and all the wprk students gather till that day. Making the family involved is another strong part of this plan to me. The things that may not work can be that it takes one month totally, so to keep the attention of the students on the same topic for such a time may be hard, maybe the project could last like two or three weeks. Also the organization of the peer groups is critical.

"impact of technology" part made me think that using technology in education is not valuable without how to use it. The project FATİH is generally taken a big step of using technology in state schools. "What is the cost?" "Are they necessary?" "Will our teachers use it?" are most asked questions. However, "How to use it?" is rare. Here with the word "use" I don't refer to running the devices. I mean the way technology be used in accordance to the educational objectives. As Chomsky says, without knowing what to do, using educational technology effectively is difficult.

There were several points that got my attention in this video. The first one was Chomsky's sentence saying that education had a value in itself. The purpose of it was to create "better" human beings, not bigger human capital for money. At this point, he opposed to idea that all generations should be given enough knowledge about math and science in order to increase people with scientific knowledge that will lead to more money income. Rather, education should foster the ideas of being independent in thoughts, being creative, having the ability and willingness to pursue one's own interest, and learning to learn on one's own. The second one was the analogy that Chomsky used. He made an analogy between technology and a hammer. He said that with a hammer you can either construct a building or smash a school down. This is about how you use the hammer, and it is the same with technology. Thus, it is more important that for what purpose we will use the technology than simply how to use technology. The last one was about achievement tests. Chomsky said that tests do not have so much value. You can pass a test after studying hard for about 3 weeks. Nevertheless, it does not mean that you will remember even the names of the topics that was covered in the exam after 3 weeks of the exam. That's why exploration, self learning, project-based learning and formative assessment is much more important and promising compared to achievement tests.

This is a lesson plan I prepared during my last year of college while I was taking school experience course and attending a public school as an intern. My proffessor Jale Çakıroğlu also liked this lesson plan very much and published it in her book named "Bilimin Doğası ve Öğretimi". Moreover, I also implemented it this semester with preservice teachers at METU. I took activity from http://www.indiana.edu/~ensiweb/lessons/gr.fs.fd.html and adapted it into Turkish. I also made some changes to make it more appropriate for 6th graders. In this activity, students are active all the time. The teacher only provides them the required materials and answer their quesions to guide them. The students work in small groups to learn the nature of science aspects with an acitivity where they act as they are scientists. The evaluation is process based not product based and this is clearly explained to the students. Since I prepared this lesson plan, actually implemented it and saw that it worked perfectly I would not change anything, but I always welcome your suggestions. :))

Gamze, thanks for sharing the lesson plan. This is an exemplary lesson plan and let's talk about it in class.
