49. Tell me how would you use assessment in your classroom?

the best units and plans aligned to standards are for naught if I don't also assess student's progress toward mastery (task).

In assessing students, I use both formative and summative assessment procedures. The types of formative assessments I use entail gathering immediate data to check for understanding. For example, I might insert a short verbal quiz into the lesson or use thumbs up/down or an exit ticket to assess class mastery of a concept. I can quickly get an idea of who needs more help and have some students work on completing a problem set in the packet while I call others together to reteach or explain differently. Summative methods include graded quizzes, tests, culminating projects, and lab reports. Throughout the term I also grade and assess participation in discussions, group projects, and timeliness turning work in.

The goal of my assessment activities is to give students and myself data to measure their growth toward mastery of each learning objective. Students can take control of their learning and I can give a grade that accurately reflects what the student knows and is able to do.

I have made a career change to teaching after working 4 years as an organic chemist and 16 years in various business roles at research vendors. I decided to become a teacher after volunteering in an AP chemisstry classroom. For two years I subbed per Diem and long term. My most recent job was teaching 10th chemistry and 7th grade science at ISB in Beaverton SD. I admire [blah blah] about [school] and that is the reason I want to teach here. My real world experience equips me to help your science students thrive under the new next generation science standards and CC.

61. Do you know how buffer works?

In buffer when hydrogen ion is added, it will neutralized by the base in buffer. Hydroxide ion will be neutralized by the acid. On the overall pH of the buffer solution, these neutralization reactions will not show much effect.

While when you select an acid as a buffer solution, try to use an acid acid that has a pH closed to your desired pH. This will help your buffer to achieve nearly equivalent amount of acid and conjugate base, so that it will enable to neutralize as much as H+ and OH.

Silicon

65. Tell me what is your greatest weakness that is really a weakness, and not a secret strength?

I have a lot of ideas for activities and I am not always a linear thinker. When I was student teaching, I expected my students to be able to move with me through lesson plans that often incorporated too many untried technologies and jumped around from one task to another. (like the time students' videotaped an assignment and then we couldn't upload and share them on EDMODO). To address this weakness, I started creating lists of my ideas and bringing them to our lesson planning team or my cooperating teacher where I would sort them and relate each one to a learning standard. This helped me prioritize and choose an anchoring activity or lab around which I was able to plan bursts of direct instruction followed by practice and formative assessment. My students noticed the change and the dynamics of the classroom moved from chaos to more orderly intentional activity. Substitute teaching has really helped me continue to strengthen my lesson organization. By teaching block lesson plans created by seasoned teachers I have been able to keep students engaged and learning in high priority activities tied to learning targets.

66. Explain about a teacher who has inspired you and what did you learn from him or her?

This kind of teacher interview question is created to discover your values and motivation. You need to prepare some examples in which show their behavior and teaching styles that inspired you.

67. Explain me what are the skills required for chemistry teacher employee in order to success in his work?

Talking to others to convey information effectively, Giving full attention to what other people are saying, taking time to understand the points being made, asking questions as appropriate, and not interrupting at inappropriate times, Using logic and reasoning to identify the strengths and weaknesses of alternative solutions, conclusions or approaches to problems, Understanding written sentences and paragraphs in work related documents, Using scientific rules and methods to solve problems.

68. Tell me what is the formula you will use to calculate how many millilitres of 5.5 M NaOH are required to prepare 400 mL of 1.5M NaOH?

To know the amount or volume of NaOH to prepare 400 mL of 1.5 M NaOH, we use formula

M1 X V1 = M2 X V2

V1 = M2 X V2/ M1

But before that we will convert 400 mL into litre = 0.4 L

5.5 X V1 = 1.5 M x 0.4 L

V1 = 1.5 M X 0.4L/ 5.5

V1= 0.10 L

V1 = 100mL

So, you need 100mL of 5.5 NaOH

69. Explain me the formula to calculate pH of a solution?

In order to calculate the pH of a solution you have to use the formula pH= -log [H+] or pH = -log [H3O+]

72. Tell me how does addition of ethylene dibromide help to petrol?

Elimination of lead oxide

73. Tell me why did you decide to become a teacher?

I am passionate about science, I enjoy working with young people, and when it came time to consider re-entering the work force I thought back to the best job I have had and that was working as a chemist. At the same time, I was volunteering as a tutor and classroom aid for a chemistry teacher at my daughter's high school. I was good at it and I loved it. The teacher and the principal both encouraged me to put the two things together into a mid-life career change and then helped me during my application process to the MAT program at University of Portland. The past three years I have been a substitute teacher in chemistry, biology and freshman physics classrooms working daily and long term. LT subbing has made my desire to teach stronger than ever and I hope to find a teaching job for the coming school year.

74. Suppose a lesson went wrong what would you do?

Things don't always go according to plan and it is wise to be able to quickly notice and adapt a lesson. A: For example, I designed a lesson plan around an apartment analogy to teach students how to populate electrons around the nucleus of an element. Even though I ran my idea for the poster project by my lesson planning team, when I actually did it with my students I saw too many not understanding the steps. R: I reflected on the gaps and revised the guided practice portion to give more opportunities together. The next class had more success creating and using their posters to write electron configurations.

75. Tell me what are your areas of strength in the curriculum?

You need to have an honest self-evaluation of your strengths. Present a clear understanding curriculum and explain why you consider those special districts as your strengths. Identify strengths that you want to enhance and the steps you will or are following to catch your goals.

76. Do you know what is dextro-rotatory and levo-rotatory?

Levorotation and Dextrorotation is referred to the properties of plane polarized light, when light rotates clockwise when it approaches the observer is then known as dextro-rotation and when the light rotates anti-clockwise then it is referred as levo-rotation.

A compound which exhibits a dextro-rotation is referred as dextro-rotatory and which exhibits levo-rotation is referred as levo-rotatory.

Avogadro's number = 6.023 X 10 (-23)

79. Tell me what is the difference between fractionation and distillation?

Both methods are used to separate the components present in the solution based on the melting points

☛ Distillation : This technique is used when boiling point of chemicals are different in the mixtures
☛ Fractionation : This technique is used when boiling point of chemicals are close to each other in the mixtures
