The effectiveness of concept-mapping in improving CHM 130 students' achievement

The effectiveness of concept mapping will be investigated in introductory chemistry students' achievement.  The researcher will test the hypothesis which stated that the implementation of concept mapping in teaching introductory chemistry will increase students’' performance.  The sample will be two sections, one will be the experimental group and another group will be the control group.  Both groups had taken a pretest.  The experimental group will draw concept maps for the units taught and will be part of their journal.  The units will include naming, moles, balancing equation, stoichiome

Particle Diagrams for picturing chemistry

Chemistry students are required to think about the atomic nature of matter, while only being able to see the macroscopic level.  To help them, we use particle (atomic) level diagrams that rely on different colors, shapes and lines to represent different types of particles, phases, reactions, and temperatures.  These models are used throughout their chemistry courses particularly when systems become too complex to describe concisely in text or formulas.  A firm grasp of understanding and drawing these diagrams is important for success in the future.  However we never directly assess individu
