Abstract
Even though several studies have reported positive attitudinal outcomes from context-based chemistry programs, methodological obstacles have prevented researchers from comparing satisfactorily the chemistry-learning outcomes between students who experience a context-based program with those who experience a content-driven program. In this narrative inquiry we are able to address the question: how do the recalled experiences of a student and her teacher in context-based and concept-based chemistry programs compare? From the student’s unique perspective of experiencing both programs with the same teacher, we have constructed our collective account around four themes; namely, the extent to which the student makes connections between chemistry concepts and real-world contexts, developing research independence through engaging in extended experimental investigations related to contexts, learning chemistry concepts through contexts, and conceptual sequencing in a context-based program. The student reported real-world connections between chemistry concepts and contexts, found her engagement in the context-driven tasks interesting and productive, and identified connected sequences of concepts across the contexts studied. Despite difficulties for teachers who are required to shift pedagogies, the student’s lived experiences and outcomes from a context-based program provide some encouragement in working through these issues.

Notes
While there are different ways of defining context-based learning, the trial pilot chemistry syllabus in Queensland defines context as “a group of learning experiences that encourages students to transfer their understanding of key concepts to situations that mirror real life” (Queensland Studies Authority 2004, p. 11). Generally, a context-based approach and related science-technology-society (STS) curricula adopt an alternative rationale for learning experiences for students than traditional or conceptually focused programs. The focus in a context-based approach is on the application of science as a means of developing scientific understanding in such a way as to develop students’ capacities to function as responsible participants in their everyday lives (Aikenhead 2006; Bennett 2005).
We group context-based and STS approaches because Bennett (2005) found it too difficult to distinguish between implemented programs aligned with each approach. Both approaches adopt an alternative rationale to more conventional programs. The focus in context-based and STS programs is on the application of science to develop students’ capacities to function as responsible participants in their everyday lives (Aikenhead 2006; Bennett 2005).

8.
Imagine you were starting year 11 again and you actually had the choice of one of the two approaches, which one would you choose and why?
Sample Questions from Interview Two
-
1.
Compared with last year, in what ways were the writing requirements similar and different this year?
-
2.
How do you think the writing that you had to do for last year’s tasks and this year’s tasks compares in terms of understanding the concepts behind it?
-
3.
How do you think that affects your understanding of the concepts that you’re doing in those two different tasks?
-
4.
I just remind you that in the last interview you said that you learnt things in more depth. Can you explain to me what you meant by you learnt it in more depth?
-
5.
So when you say you have learnt things in more depth can you give me an example of differences between this year and last year? How did you learn something in more depth this year?
-
6.
And also in the last interview you made a comment about how you personally like to see how the chemistry is applied to real situations. You said you like to see the purpose of the chemistry. Can you explain what you meant by this?
