# Ionic Bonding Rationale

Rationale

I decided to turn this lesson into a flipped lesson as the topic on ionic bonding is something very microscopic and I feel it would help students to develop a more concrete understanding of an abstract topic. By recording the lecture which includes a step-by-step guide on drawing a dot-and-cross diagram, the weaker ones will be able to study at their pace and choose to pause or rewind should they not understand. This helps them to understand the concepts better, as opposed to going slowly in class if it were a traditional classroom setting.

Following the flip lesson, the next day, students are able to clarify any doubts and consolidate their learning. The in-class activities helps to facilitate the students’ learning via interactive
To check for students’ understanding and ability in identifying the ions of the constituent atoms and its respective charge.

Scaffolding provides guidance to weaker students and prevents them from ‘switching off’.
To allow students to be active participants during the lesson. The students are expected to work together to complete the activity. This helps to promote collaborative learning.

Allowing students to understand the formation of ionic bonds by using models helps to bridge the gap from micro level to symbolic. It makes it less abstract for them.

The teacher will still provide assistance to the students when needed and intervene by asking questions to stimulate student thinking.

15 mins Lesson Worksheet:
Hereon, they are to attempt the worksheet individually where they are required to draw the ‘dot and cross’ diagrams for the same 4 compounds they were assign in the previous activity. Teacher will remain as a facilitator.

After the starter activity, students should attain a better understanding with respect to the number of ions involved in forming trickier ionic compounds. (e.g. in MgCl2, there needs to be 2 Cl– ions with a total charge of –2 to balance out the +2 charge on the Mg2+ ion so Mg will donate 1 electron to each of the chlorine

• ## Pythagorean Theorem Essay

However, by the end of the week/unit, the students will receive a summative assessment to demonstrate their understanding of using the Pythagorean Theorem to identify the missing leg or hypotenuse of a right triangle. Procedure: Before the lesson (Do Now): To help the students be successful with using the Pythagorean Theorem, the students will review what it means if a number is squared, square roots, and solving expressions with single digit exponents. To ensure that the students understood the Do Now, the teacher will call on volunteers to solve each problem. Introduction: Before beginning the mini-lesson, the teacher will review some vocabulary words that students will need to know in order to be successful in today’s lesson. These vocabulary words are Pythagorean Theorem, right triangle, and hypotenuse.…

The teacher will then pull up the poster that the teacher and the students made together the other day in class. The teacher will review the poster with the students, and the teacher will call on some students to read the poster to the other students; for example (pointing to the first shape), “What is this shape’s name?” “How many faces does this shape have?” “What are some examples of this shape?” and allow different students to answer these questions. 2. After the teacher and the students review the poster the teacher will tell the students that they are now going to look at a poem that the teacher found about 3D shapes. The teacher will pull the poster up with the poem and read the student’s the title.…

• ## Essay On My Flipped Math Classroom

Students then took a lesson quiz over the learning goal, and they received immediate feedback on their email. Those students who received feedback indicating they were non proficient on the learning goal were directed to the back table for reteaching. Since Ms. Yoder was absent, we planned for me to provide reteaching to the students, and the substitute to keep a close eye on the students who were working independently at their desks. During the reteaching, I followed a direct lesson framework with the “I Do, We Do, You Do” process, so students were clearly shown how to complete the problems correctly before completing more problems with guided practice and independence. Student M was part of my group, and he benefited from this extra instruction and practice, as did other students.…

• ## Long Grammar Effect

As mentioned before, the student’s errors focused the most on sentence structure, usage, and mechanics. In order to correct the mistakes that the students were making, I noticed that the strategy used was a process of steps. For starters, the teacher used a table or model to read and analyze the recorded errors. According to the errors, the teacher designed a mini lesson to present to the class so the students recognize how to correct their mistakes. Lastly, the teacher collected the student’s writing again, to re-analyze, and determine if there was any progress or if there was not.…

• ## Grit Reflection

My students tend to be most accountable when they have created and written a specific and concrete plan for their success. Having a specific set of steps that they might follow to develop grit in challenging circumstances would make it more likely that they would follow through and actually work on developing grit. For example, instead of just continuing to try in math class when confused, my student could have made a plan that such as “First, I will re-read the question. Then, I will look at similar problems on the page. If that doesn’t work, I will review my notes, and if I am still stuck, then I will ask my teacher for help.” Another example of a more concrete plan might be that if a student does not pass an assignment, they might first read the feedback on the assignment, then consult their notes, and last, ask the teacher for additional support.…

• ## Informative Essay On Formative Assessment

For instance, a lesson has just been taught about Pythagorean’s Theorem and its applications. There are 3-5 minutes left in class and the students are asked to construct an answer to the prompt which has been projected onto the Smart Board. A prompt such as, “Explain how to solve for a leg of a right triangle using complete sentences.” would allow the teacher to assess if his or her students had understood the conceptual aspects of the days lesson, while, also, implementing writing into a mathematical setting. Based on the results, what adjustments could be made: Based on the results of this assignment, the teacher could establish if his or her lesson had been understood by the majority of the class and could help identify which students are struggling with the material. The teacher could decide to spend more time on the subject or pull students aside for some extra practice or explanation.…

Students will determine how much time they will spend at each station. Students will determine as a group which station they will complete first. After each group has completed all workstations, students will share their accomplishments at each station and explain what else they might want to learn about measurement individually. After explaining the workstation steps, the educators will be allowed to choose three of Bloom’s Taxonomy level workstations to practice that they are not comfortable presenting to students. Similarly, Piaget’s preoperational stage and Vygotsky’s concept of scaffolding both target how children learn based upon their developmental level.…
