Facilitating grade 11 students' conceptual understanding of fundamental acid-base models
Öz: The purpose of this study was to enhance grade 11 students’ conceptual understanding of fundamental acid-base models using Predict-Observe-Explain based animated movies (POE-AM). Twelve grade 11 students participated in the study. To collect data, the students’ responses to the POE-AM tasks and interview protocols were used. The findings indicated that the POE-AM tasks positively improved the students’ conceptual understanding of fundamental acid-base models and remedied any deficiency identified in pre-interviews and/or the ‘predict’ stage of the POE strategy. The results also showed that before implementation the students stated the main parts of acids and bases as H+ and OH- ions, respectively. After the implementation, they indicated that the Arrhenius model had the least adequate explanation to imply features/behaviors of acids and bases whilst the Lewis model did the most adequate acid-base definition to address their features/behaviors. Moreover, the study revealed that most of the students had alternative understanding or only partial understanding at the ‘predict’, but showed somewhat a sound understanding of these concepts at the ‘observe’ and ‘explain’ stages. The current study suggests that chemistry teachers should integrate the POE-AM into their classes to effectively promote student learning.
Anahtar Kelime: 11. Sınıf öğrencilerinin temel asit-baz modelleriyle ilgili kavramsal anlamalarını kolaylaştırma
Öz: Bu çalışma, 11. sınıf öğrencilerinin temel asit-baz modelleriyle ilgili kavramsal anlamalarını Tahmin-Gözlem-Açıklama temelli animasyon filmleriyle (TGA-AF) artırmayı amaçlamaktadır. Çalışmaya 12 onbirinci sınıf öğrencisi katılmıştır. Veri toplamak için öğrencilerin TGA-AF etkinliklerine ve mülakat protokollerine verdikleri cevaplar kullanılmıştır. Elde edilen bulgular, TGA-AF etkinliklerinin öğrencilerin temel asit-baz modelleriyle ilgili kavramsal anlamalarını pozitif olarak geliştirdiğini ve ön mülakatlarda ve/veya TGA stratejisinin tahmin aşamasında belirlenen eksiklikleri giderdiğini göstermiştir. Öğrenciler uygulamadan önce asit ve bazların temel bölümlerinin sırasıyla H+ ve OH- iyonları olduğunu ifade etmiştir. Uygulamadan sonra ise öğrenciler asit ve bazların özelliklerini ve davranışlarını açıklamak için Arrhenius modelinin en az ve Lewis modelinin ise en çok yeterli açıklamaya sahip olduğunu belirtmişlerdir. Ayrıca, öğrencilerin çoğunluğunun TGA’nın “tahmin” aşamasında alternatif ya da kısmi anlamaya sahip olduğu; ancak, “gözlem” ve “açıklama” aşamalarında belli bir dereceye kadar tam anlamayı gösterdikleri ortaya çıkmıştır. Bu çalışma, kimya öğretmenlerinin öğrencinin öğrenmesini etkili olarak teşvik etmek için TGA-AF’yi kendi sınıflarına entegre etmelerini önermektedir.
