The Subject

This study aimed to determine the contribution of multiple representation-based learning through cognitive dissonance strategy and to reduce misconceptions encountered by chemistry students. A mixed method research with the embedded experimental design was employed in this study involving 66 sophomore students enrolled in the Basics of Analytical Chemistry class. This study used a threetier test diagnostic test of 43 questions that had been validated by the education teams and chemists. The analysis was done by using a t-test and N-gain. The results showed a significant difference between the experimental and the control classes and a greater increase in N-gain in the experimental class (68.56%) compared to the control class (42.42%). The most effective reduction of misconceptions occurred in the subject of argentometric titration, from 33.41 to 8.79 %. This indicates that MRCD cannot completely eliminate misconceptions, especially for concepts related to sub-microscopic and symbolic representations.

Cognitive Awareness

The purpose of present study is to examine the role of learning strategies as moderator between meta-cognitive awareness and study habits among university students. Sample comprises of 200 students (100 male students and 100 female students) of various universities of Islamabad and Rawalpindi with age ranging from 18-25 years. In order to assess study variables questionnaires were used included Meta-Cognitive Awareness Inventory (Schraw & Dennison, 1994) measuring two-components of meta-cognition that are knowledge and regulation of cognition. Study habits demonstrated by the students were measured by the Study Habits Inventory (Wrenn, 1941). Motivated Strategies for Learning Questionnaire (Pintrich, Smith, Garcia, & McKeachie, 1991) which includes motivation and learning strategies scales. In the present study, only the learning strategies section was utilized, which measures the cognitive strategies and resource management strategies. Results revealed positive correlation between research instruments and are also having good reliability. Regression analysis reflected that meta-cognitive awareness predicts study habits among university students. Regression analysis also suggested that learning strategies including resource management strategies and cognitive strategies significantly moderates the relationship between meta-cognitive awareness and study habits. It is also explored gender differences on learning strategies, meta-cognitive awareness and study habits. Future implications of the study were also discussed.
