The purpose of this study was to identify university students’ conceptual understanding and alternative conceptions in qualitative analysis. For this reason, a 19 items two-tier multiple choice test administered 301 second year university students in spring semester 2004. Analysis of results showed that students find difficulty about conceptual understanding and they have some alternative conceptions related to displacement reactions, redox, dissolution, addition of acid and heating in qualitative analysis

Anahtar Kelimeler

Qualitative analysis, Displacement reactions

ÜNİVERSİTE ÖĞRENCİLERİNİN NİTEL ANALİZ KONUSUNDAKİ KAVRAMLARI ANLAMALARI VE ALTERNATİF KAVRAMLARININ İKİ AŞAMALI TESTLE BELİRLENMESİ

Öz

Bu çalışmanın amacı üniversite öğrencilerinin nitel analiz konusundaki kavramları anlama düzeylerinin ve alternatif kavramlarının belirlenmesidir. Bu nedenle iki aşamalı 19 sorudan oluşan çoktan seçmeli test 301 üniversite 2. sınıf öğrencisine 2004 yılı bahar döneminde uygulanmıştır. Sonuçların analizi ile öğrencilerin nitel analiz konusundaki kavramları nedenleri ile birlikte anlamada zorlandıkları ve nitel analiz konusu ile ilgili yer değiştirme tepkimeleri, redoks, çözünme, asit ilavesi ve ısıtmayla ilgili alternatif kavramlarının olduğu tespit edilmiştir.

Anahtar Kelimeler

Nitel analiz, Yer değiştirme tepkimeleri
