Applying Baamboozle to teach English vocabulary for pre-starter level at a language center in HCMC

/in /by

This study investigates the effectiveness of Baamboozle, a digital game-based learning tool, in teaching English vocabulary to Pre-Starter level students at Phuong Nam Language Center, Ho Chi Minh City. Quantitative and qualitative methods are employed. Quantitative data was obtained from questionnaires and tests while qualitative data was collected from interviews. 88 Pre-Starter level students and 17 teachers at Phuong Nam Language Center, Ho Chi Minh City participated in the research. The findings reveal that Baamboozle significantly improves students’ vocabulary acquisition and students’ engagement compared to traditional methods. Both teachers and students expressed a positive attitude toward the Bamboozle tool, appreciating its interactive and enjoyable nature. However, the study also highlights some challenges when using the tool such as inconsistent use across classes and content repetitiveness. The study recommends regular integration of Baamboozle into English lessons supported by teacher training, and suggests further research on its long-term effects in language learning. This study adds valuable insights into the use of educational technology to enhance language instruction.

Subclinical Hypothyroidism Post-Bariatric Surgery: A Reversible Case of Iodine Deficiency Without Autoimmune Thyroid Disease

/in /by

Subclinical hypothyroidism is a common finding in clinical practice, often prompting initiation of levothyroxine therapy. However, not all cases of elevated thyroid-stimulating hormone (TSH) reflect permanent thyroid dysfunction. This report discusses a 39-year-old woman with a history of Roux-en-Y gastric bypass surgery who presented with elevated TSH in the absence of thyroid autoantibodies or classic hypothyroid symptoms. Laboratory and clinical findings suggested iodine deficiency as the underlying cause. Her TSH normalized following potassium iodide supplementation. This case underscores the need for a nuanced approach to managing elevated TSH, particularly in post-bariatric surgery patients where iodine deficiency may be the etiology of subclinical hypothyroidism.

The Development of Ethnomathematics-Based Learning Devices of Sulur Godong Batik Using Digital Manipulatives on Geometry Transformation to Improve Students Creative Thinking Abilities

/in /by

The research conducted aims to create learning devices that can be declared valid, practical, and effective, especially on the subject of Geometric Transformation. The development of this learning device is carried out with the aim of improving students’ creative thinking skills. This research is a type of research and development with the 4-D Thiagarajan development model. The stages of 4-D Thiagarajan include define, design, develop, and disseminate. Data collection is carried out using observation, test, and questionnaire techniques. The results of the Ethnomathematics-based development research using digital manipulatives are classified into valid, practical, and effective. The level of validity can be seen from the validity value of each teaching module of 3.78, LKPD of 3.87, and test of 3.92 which are included in the valid category. The practicality value is obtained from the results of observations of the implementation of learning devices and the results of observations of student activities of 92.25% and 93.08%, respectively. The effectiveness value is seen from the learning outcome data obtained 83.0% completed classically with the category of very creative and creative thinking and the student response questionnaire has a positive value of 88.2%. Suggestions for teachers are expected to use learning devices more often because they can train students’ creative thinking skills and can be used as a guideline in a more varied and innovative learning process. Not only that, other researchers can reach wider research subjects and different materials in the development of further learning devices.
