Contribution

Owing to the introduction of educational standards, the focus of school science curricula in many countries has changed (Abd-El-Khalick et al., 1993; Hofstein, 2004; van Joolingen, de Jong, & Dimitrakopoulou, 2007). Nowadays, inquiry skills are increasingly required (e.g. KMK, 2007; NRC, 2012). To adequately train students in this regard, teachers should be prepared by acquiring inquiry skills themselves (Gyllenpalm, Wickman, & Holmgren, 2010; KMK, 2010). However, some studies show that teachers have problems in conducting experiments individually and are mostly unfamiliar with the concepts of scientific inquiry (Gallagher, 1991; Gyllenpalm, Wickman, & Holmgren, 2010). Moreover, some authors argue that aspects of scientific inquiry are hardly taken into account in university teacher training (Hofstein & Lunetta, 2004; Seung, Bryan, & Butler, 2009).

While many studies focussing on inquiry skills of students or teachers (e.g. Baxter & Shavelson, 1994; Gallagher, 1991), there appears to be little empirical research on teacher education in this area. But it is important to understand what foundations are laid here and where there is still potential for development. Thus, the aim of this research is to describe the inquiry skills of pre-service teachers and to review learning opportunities in the context of universities’ teacher education. Thereby, we exemplarily view at chemistry pre-service teachers. In particular, we investigate the following research questions:

(1) Which inquiry skills can be identified in experimental procedures of chemistry pre-service teachers?

(2) Which learning opportunities regarding inquiry skills do pre-service teachers perceive in their learning biography?

In the present study, inquiry skills are regarded as skills required to perform a process of knowledge acquisition by using different methods such as literature research, experimentation or observation. Since experimentation is an important method of science (Driver, Leach, Millar, & Scott, 1996), the proposed research will focus on the inquiry skills that are required for conducting experiments. These skills are linked to the elements of experimentation: (a) asking questions, (b) generating hypotheses, (c) planning an experiment, (d) conducting an experiment, and (e) evaluating evidence (e.g. Hofstein, 2004). Various authors have already specified skills required for experimentation (e.g. Lunetta, & Tamir, 1979). We have summarised them in a catalogue of inquiry skills (Patzwaldt, Kambach, Upmeier, & Tiemann, 2013) including several inquiry skills for each element of experimentation. For example “generating hypotheses” contains (b1) investigating sources of information, (b2) consulting previous knowledge, (b3) consulting experimental data, (b4) formulating hypothesis (identifying dependent and independent variables, selecting variables, selecting a relation to hold between two or more variables), and (b5) checking the plausibility of the hypothesis. Since these skills relate to cognitive activities, our catalogue also contains many inquiry skills referring to practical activities (e.g. arranging equipment).

To investigate the inquiry skills of pre-service teachers we use hands-on investigation tasks as they serve as a benchmark in many studies (e.g. Baxter & Shavelson, 1994). Furthermore, we apply the method of “Concurrent Think Aloud” (Ericsson & Simon, 1993) and “Focused Interviews” (Merton, Fiske, & Kendall, 1990) as well as video analysis to get a deeper understanding of inquiry processes.

The results of our study are to provide a more accurate description of the aspects of inquiry skills and allow identifying learning opportunities in learning biographies of pre-service teachers.

Method

In order to analyse pre-service teachers’ inquiry skills, we developed seven experimental tasks in which they are asked to investigate a causal relationship in a chemical context. In line with the five elements of experimentation (see above) each experimental task consists of five subtasks. In order to solve the task, laboratory equipment, chemicals, and short texts with background information were available. We asked 25 chemistry pre-service teachers to solve these tasks on their own and to talk aloud all their thoughts at the same time. This method of “Concurrent Think Aloud” (Ericsson & Simon, 1993) has been used in order to obtain in-depth knowledge about the processes and problems involved in inquiry processes. In addition we adapt the method of video analysis to analyse aspects that are not accompanied with thoughts, such as for example the use of devices. Finally, participants recapitulated their experimental processes as well as their learning opportunities regarding inquiry skills in a “Focused Interviews” (Merton, Fiske, & Kendall, 1990). So we were able to identify their meta-knowledge about experimentation and individually perceived learning opportunities. A theory-driven catalogue of inquiry skills (Patzwaldt, Kambach, Upmeier, & Tiemann, 2013) served as a theoretical framework in this study. Based on that we designed a coding guideline to analyse videos and think aloud protocols. We have considered 5 categories. For this study, we describe them as follows: - Questioning: formulating a question that is to be studied - Hypothesizing: defining variables, formulating hypotheses - Planning: describing, how the experiment will be practically conducted - Conducting: practically preparing measurements, measuring, observing, documenting measurements - Evaluating: analysing and/or interpreting data, reflecting, referring to hypothesis Each of these categories comprised further subcategories, providing a detailed description of individual skills. There has also been a sixth category called ‘Others’, which includes actions and thoughts, which could not be assigned to a specific inquiry phase. These are for example ‘dealing with problems’, ‘reading the given information’ or ‘talking off topic’. Furthermore, we coded whether the participant is running through the exploration phase or if he is dealing with one of the 5 subtasks. Consequently, we were able to analyse in which subtask the proposed skills and problems occurred. As a result of coding, we obtained a list of observable skills as well as diagrams showing the individual chronological sequence of an inquiry process.

Expected Outcomes

Overall, the duration of individual inquiry processes took a wide range from its minimum of 18 min to its maximum of 1 h 35 min with a median of 43 min. In every video, conducting the experiment took the longest time. Also, there was no pre-service teacher who formulated a research question as the basis for subsequent investigation. Every participant has formulated a hypothesis and described an action plan. The phase of evaluating has been very short or even ignored. In the first part of our analysis, we evaluated the think aloud protocols and found a variety of inquiry patterns. These different patterns seemed to be independent from the task, as they could be observed in every experimental task. Furthermore, these inquiry patterns were consistent with theory claiming that inquiry processes do not follow only one characteristic pattern (e.g. McComas, 1998). In contrast to our expectations, the video analyses did not reveal additional findings, since students already verbalized their actions. Consequently, these data were part of think aloud protocols. As the analysis of interview transcripts shows, the participants rarely experimented during their school education. Therefore, most of them consider their inquiry skills to be low. Otherwise, four participants are already skilled laboratory assistants and consequently feel well educated. However, all interviewed pre-service teachers hardly perceived learning opportunities relating to inquiry in university chemistry teacher education. These findings are in line with findings from Hofstein and Lunetta (2004) as well as Seung, Bryan, and Butler (2009) and indicate a lack in our universities teacher training. An important contribution of the study is the development of a coding guideline, which serves as a tool to analyse inquiry processes. We are therefore able to provide specific interventions to improve inquiry skills.
