Article 2: Background Of The Study
• Practical work was rarely happening in most schools because standard equipment and chemicals were too expensive to purchase.
• The need to carry out practical chemistry on a much more reduced scale, in order to save chemicals, time, and ease disposal problems became increasingly important.
• The benefits of micro-scale in the context of developing countries are exemplified by a small number of studies only (bradley, 2000)
• A few limitations exists in the practice of micro-scale chemistry techniques (bradley,1999)

Objective
• To explore the possibility to use micro-scale chemistry approach as a means to perform practical activities in chemistry classes, hence reducing the need for highly equipped laboratories, but also providing opportunities for students to engage in a process of active learning

Research Questions
• What is the teachers’ opinion about the MSCE approach?
• What is the students’ opinion about the MSCE approach?
• What is the impact of the MSCE approach on cognitive learning?

Research design
• Quasi-experimental design

Sample / Population
• 195 science students• 145 male and 50 female aged between
17–19 years participated in the study• Control school: 107 students (all boys)• Experimental school: 80 students (38
boys, 50 girls)

Sampling technique
• Purposive sampling

Instrument
• Student achievement test• Observation • Interviews • Questionnaires

Data Analysis Procedure
• Independent sample t-test• Descriptive statistic

Main Findings
• The overall teachers’ and students’ reactions to the MSCE approach were vastly positive
• Most students’ were excited with the micro-scale experiments experience and they it easy, more interactive and enjoyable, allowing them to carry out experiments for themselves, collaborate with peers and communicate with their teachers freely

Implications
• The MSCE approach developed in this study with exemplary lesson materials, containing adequate procedural specifications are feasible for use in A-level chemistry classes
• Effective in providing positive learning experiences for students.
