Grade 6 - Dr. Holger Meinberg

Grade 6 students embarked on an investigation into the fascinating phenomenon of light refraction. They began with an activity where they observed a chopstick appearing bent when placed in water and explored the observation of coins in a cup with and without water. These hands-on experiments allowed students to witness the effects of refraction firsthand. To reinforce their understanding, students utilized a simulation that provided a virtual environment to explore and interact with refraction. This simulation enabled them to become more familiar with the concept and apply it to solve practice questions. Impressively, one student even managed to represent total internal refraction using the simulation.

The project not only honed their research and writing skills but also deepened their appreciation for the nuanced interplay between cultural narratives and empirical discoveries. Through their diligent efforts, Ms. Exum's students bridged the gap between myth and science, demonstrating the evolving nature of human understanding.

Grade 10 - Mr. Nick Smith

On Monday students sat a summative assessment of their studies on Current electricity and Ohm's Law. The summative also included assessment of the laboratory learnings. I was pleased with the overall results. Some individuals need to improve but as a whole the Grade 10 Science students are working together cohesively and collaboratively to achieve very good results. At the close of the week the students have been designing a laboratory exploration. They are not required to do the exploration just to design it. This is proving challenging as science students are, in general,  "doers". It has been a very good thinking exercise for the students and prepares them for higher science studies.

Biology Class - Grade 11 - Ms. Marina Baltikian

In Ms. Marina's class this week, our DP1 students continued their deep dive into theme B1.1, focusing on the captivating world of Carbohydrates and Lipids. In addition to our theme studies, a few students have taken the initiative and submitted their DNA models. This demonstrates their commitment to the subject matter and their dedication to their assignments. Their efforts are truly commendable, and I encourage all students to complete and submit their models as it not only reinforces their learning but also showcases their creativity and scientific understanding. As we move forward, I encourage all students to actively engage in the upcoming lessons and assignments. Commitment to learning and exploration is the key to your success in the DP1 biology course.

The students are now part way through understanding solutions to calculate concentration and calculate dilutions of solutions.

Chemistry Class - Grade 12 - Mr. Nick Smith

The drafts of the Chemistry IA's continue to trickle in. The topic of equilibrium has been completed. The topic is short but quite complex.  The equilibrium theory for HL students included calculation of Equilibrium constants, the factors affecting the position of the equilibrium constant and the value of the equilibrium constant. Higher level students also related equilibrium to Gibbs Free Energy to determine whether a reaction is spontaneous. I see that students are now struggling with time management as many have assignments due and a busy time shcedule. No practical was held this week.

ESS Class - Grade 11 - Mr. Samuel Ward

In Grade 11, the focus of study is sub-topic 1.5: Humans and Pollution. At the onset of the week, the students engaged in a debate centered around the advantages and disadvantages of employing DDT as a means to combat malaria. Our analysis included an examination of India's persistent use of this chemical and the detrimental impact it has had, despite its reduced effectiveness against malaria.

Later in the week, the Grade 11 students were tasked with researching a specific form of pollution. Consequently, they began the construction of a systems diagram that visually represents the inputs and outputs, flows and storages, transfers and transformations associated with the chosen type of pollution. This exercise ties in with the knowledge acquired during sub-topic 1.2: Systems and Models.

ESS Class - Grade 12 - Mr. Samuel Ward

As for Grade 12, they presented to their peers about two different food production systems of their choosing. For example, subsistence farming in India, or commercial pig farming in the USA. They demonstrated many excellent skills such as in research, creating a presentation, and public speaking. We then transitioned into planning for a long-term study focused on monitoring the air quality in the vicinity of CISH, their home, and HeFei, depending on their chosen scope. This student-led activity requires the creation of their own methodology. This practical application of their knowledge in Environmental Systems and Societies (ESS) serves as a valuable opportunity to address environmental concerns specific to their local community.

Physics Class - Grade 11 - Mr. Geofrey Kivisha

This week, eleventh graders studied the intricacies of circular motion in physics class, gaining knowledge of fundamental formulas including linear velocity, angular velocity, frequency, and period.

In AA DP1, students covered the concept of inverses. Inverse functions, a vital tool for reversing the process of a given function, have been thoroughly studied, enabling students to solve equations and grasp the relationships between variables. Students have likely gained the knowledge to find inverse functions and apply them to a variety of mathematical problems.

Garde 12

In AA DP2, the second year of the IB Diploma Program, students have completed their preparations for a significant milestone - their calculus mock assessments. These assessments are a pivotal part of the curriculum, particularly for both Higher Level (HL) and Standard Level (SL) students as they contributed a better understanding of the student’s overall progress in the course due to the comprehensive nature of the mock examinations.

AI DP1 and DP2

In AI DP, we reviewed the test on the first half of Unit 1 that was given to them for homework. We started looking at advanced probability theory and motivated the Binomial distribution in some detail. 

G1 Beginner EAL - Tom Wickham

With the alphabet concluded, we have been focusing on both vowel and consonant recognition and blends. We also began with the sight words: there, were, some, they, said. We have also been covering the magic e. Most students are now competent with CVC construction and pronunciation including using the magic e. Focus on listening comprehension has been effective. Focus on pq and bd distinction has also been effective. Overall class improvement is noticeable.

G1 Intermediate EAL - Hercus Theron

This week, the grade 1 students continued learning about phonics. We reviewed the short vowel sound ‘o’. We built CVC words using the vowel sound. We also learned about nouns and how to categorize the different kinds of nouns. During story time, we practiced reading short ‘a’ and short ’o’ word stories. We also learned about regret in a story about a mouse who wanted to fly. Next week, there will be more phonics and reading as well as a creative exercise to practice speaking and listening.

G2 Beginner EAL - Tom Wickham

Now that students have completed the alphabet, we have been focusing on both consonant and vowel recognition and blends. We have also been covering the magic e and using it during CVC construction activities. All students are now competent with CVC construction and pronunciation and some using the magic e. Overall class improvement is noticeable. We will focus on exercises to practise blends going forward. Will also begin to introduce prepositions.

G2 Intermediate EAL - Hercus Theron

The grade 2 students this week continued to learn about ‘r’ blends. We also reviewed nouns and the different types of nouns. Students had to categorize nouns and also use some of the words in sentences. After students visited the zoo on Thursday, we gave each student an opportunity to speak about their favorite part of the zoo visit and their favorite animals. We then played some interactive games to practice vocabulary and phonics.

G2 Intermediate EAL - Chris Marionni

In Mr. Marionni’s G2 Intermediate EAL, students read the short story “Ian’s Halloween Costume”, discussed the story in detail, answered story questions (both verbally and in writing), and focused on story vocabulary using visuals. On Wednesday, students focused on regular plural nouns and used IXL for extended practice. On Thursday and Friday, students focused on writing; this week, students completed sentences in a paragraph about the Halloween costume they chose for this year. At the end of class on Friday, students played a vocabulary game where reading and listening skills were also a focus.

G3 Beginner EAL - Tom Wickham

Continuing to review nouns, pronouns, verbs and adjectives as progress has been slow. Sight word recognition is much improved using the ‘I have, who has’ card game but decodable phonic reading needs more attention. From observation of written work and student response, we will be reviewing more phonic based reading. Will be using more basic CVC, CVVC and CVCC construction going forward. Some slow progress in some areas but readjusting the difficulty level of exercises should be effective. Also covering relevant vocabulary for homeroom’s Unit of Inquiry.

G3 Intermediate EAL - Hercus Theron

In Grade 3 this week, we read a story about cloud watching. We also learned about different perspectives. Students got to look at some abstract pictures and then had to vote about what it is they think the image is, or what it looks like. There was also time to review a few blends during our phonics lesson. Students learned about Icarus and how he regretted flying too close to the sun. After that, students had to write their own story about regret. 

G4 & G5 Beginner EAL - Tom Wickham

Grade 4&5 have benefited from more active team-based exercises including charades. Will continue to pursue more team-based approaches as it seems to work well with the group. Additionally, presentations have proved effective for maintaining focus during writing activities and the finished work being displayed has had a motivating effect. Duolingo continues to be popular as a homework activity among students and they regularly spend upwards of 45 minutes a week using the program. To focus on reading comprehension and facilitate regular book reports as part of EAL, a weekly library visit has been arranged.

G4 & G5 Intermediate EAL - Hercus Theron

This week, we did a lot of different writing activities that gave us lots of opportunities to learn better writing habits. We looked at using different words when starting new sentences rather than using the same sentence structures or continuously using words like ‘and’, ‘but’, and ‘then’. There was also time for reading practice and comprehension. As well as reviewing phonics and grammar rules.

G4 & G5 Intermediate EAL - Chris Marionni

In Mr. Marionni’s G4 & G5 Intermediate EAL, students read the short story “The Haunted Tree”, discussed the story in detail, answered story questions (both verbally and in writing), and focused on story vocabulary using visuals. On Wednesday, students focused on adjectives and then used IXL for extended practice. On Thursday and Friday, students completed a one-paragraph writing assignment connected to the short story and grammar focus of the week. At the end of class on Friday, students played a vocabulary game where reading and listening skills were also a focus.

G6 & G7 EAL - Richard McNamara

Throughout the week in EAL, sixth-graders worked on finishing and practicing for their summative I&S research project. In contrast, 7th graders, in advance of class, investigated the fundamental elements of agriculture and industry's societal roles and completed two review exercises to improve their Unit 1 I&S summative test results from last term. In Science, 6th-grade studied color formation (absorption, reflection, light bending, and refraction). 7th-grade students edited and presented a weather video. In I&S, the 6th grade completed and presented a modified Unit 1 research project. 7th-grade EAL began a worksheet describing the historical stages of the agricultural revolution in detail.

G8 & G9 EAL - Anuschka Etsebeth

This week in grade 8 EAL, we began by previewing vocabulary related to I&S reading about eruptions. In Science, we reviewed dependent, independent, and variable factors. We also looked at different supplies and discussed how they could be used in our experiment. In grade 9 EAL this week, we discussed the importance of completing tasks and provided students with the necessary materials. In Science class, we emphasized staying on topic and using one's own words. We previewed a reading activity for I&S by providing a short summary with lots of pictures to make it easier for students to understand. At last, we covered the topic of personal hygiene and listed translations with practical examples on the board.

G10 EAL - Ayana Najuma

This week in Ms. Najuma's grade 10 EAL class, students focused on activities that enhanced their understanding of the mob/mot/mov root. They also worked on developing the skill of identifying the main idea at their own learning levels. Students worked on identifying key parts of essays, such as, the in-text citation, quotation vs. paraphrase, and the author’s argument or opinion. Additionally, students were frontloaded three videos and engaged in discussions related to their I&S class.
