ABSTRACT

This study investigates two latent constructs (Engagement and Value) of dialogic interaction to examine the epistemic climate. Since the new reform movement emphasizes creating generative learning environments, it is important to examine whether a classroom promotes students’ knowledge generation or limit students’ epistemicgrowth through rote memorization. At this point, it is inevitable to focus on dialogic interaction (one of the epistemic practices), because how students engage with and view dialogic interaction provides meaningful information about the epistemic climate. By employing Rasch modeling, this study tested a statistical validity of two latent constructs of dialogic interaction. The findings in this study highlight that the two latent constructs are theoretically and statistically valid and can be used to gauge the epistemic climate through students’ engagement with and value of dialogic interaction. While understanding the epistemic climate cannot solely occur through a single perspective, this study plays a significant role in adding a valid instrument. Such instruments help researchers comprehend the epistemic features of learning environments and provide a practical way to reflect students' lived experiences to learn about the overall atmosphere of the learning environment.

[Home-Baking] Whole-Wheat Ricotta Cheese Cobbler

If you want to eat fruit differently, there is a cobbler recipe that you can easily make at home. There are so many different types of cobblers, and there are many different types of cobblers in each household. While it is easy to make, the taste is deep and light (?). This time, I decided to try making it healthier by using especially whole wheat flour. First, lightly wash the blueberries and place them on a sieve. Rub the outside of the apple with baking soda, clean it, and cut it into small pieces. I needed about 3 tablespoons of butter, but I only have 2.5 tablespoons left, so I'll just use it as is. Chop it up into small pieces and place it in a baking glass bowl. Put it in the microwave for 45 seconds and it melts so well. You can use sugar or honey, but I found quince jam left in the refrigerator for a while and decided to use it today. Take a large tablespoon of jam and spread it on top of the melted butter. Sift 1 cup whole wheat flour through a sieve Sprinkle two tablespo...

Mental Wellbeing Check-in Activity - Draw Emojis

Today's topic is my past week expressed with emoticons. Usually, in this activity, the teacher puts emoticons on the screen and asks the students to choose them, but in my class, I had the students draw them directly to add a more creative element. It was an early morning class, so even the students who rushed in felt that it was helpful to calm the students' emotions as they were able to catch their breath and draw slowly as soon as they started the activity. Student B, who tried to capture a lot of happy expressions by changing colors Student A is proud that her emoji has hair
