Sources Of Students’ Difficulties In Learning Chemistry, David F. Treagust, Reinders Duit, Martina Nieswandt

Administration and Staff Articles and Research

Chemistry is a difficult subject to teach and to learn at both secondary and tertiary levels. Major learning difficulties are due to the particular views of chemistry phenomena that in many ways contradict intuitive and everyday views of the learners. As a result, major misunderstandings occur when students try to comprehend chemical explanations within the framework of their pre-instructional conceptions. This paper describes research findings on students’ pre-instructional conceptions in the domain of chemistry and on attempts to guide students from their conceptions to the core ideas of chemistry. Rather than providing an overview of students’ conceptions in various topics, …

Flipping The Flipped: The Co-Creational Classroom, Vuk Uskoković

Pharmacy Faculty Articles and Research

The flip teaching model is being increasingly adopted by higher education institutions as an active learning alternative to traditional lecturing. However, the flip model shares a number of critical premises with the classical didactics. The further flips of the flip are thus advocated and the fear of returning the method to its initial state, prior to the flip, via such flips of the flipped dispelled. Proposed here is a seminal variation to the flip model based on the active involvement of students in searching, finding, selecting, and assembling knowledge from various literature sources into the learning material for the entire …
