WHY PROCESS ANALYSIS?

‒ Learning process is affected by previous

learning experiences, and that these

experiences influence each other

between and within tasks (Molenaar &

Chiu, 2013).

‒ When we want to investigate how

individuals and groups engage to

learning, there is a need to consider both

order (sequential) and temporality

(temporality) of meaningful events, to

better understand how learning is shaped

in a situation.

EVENT DATA ‒ How often a certain event occurs in the data?

‒ Time stamped information

1) Need to categorise the data.

- Data driven approach (e.g. logdata, navigational

data)

- Theory driven categories (events under theoretical

interest)

2) Problems

- Some events might occur often

- Categories needs to be reduced

- Often includes multiple rounds of analysis

Sequential and temporal analysis is based on

the events that are recorded or categorised

from the raw data as they occur (involve time

stamps and some event information) and

result often in abstracted models that mirror

reality

WAYS TO DO PROCESS ANALYSIS?

‒ Multiple methods and techniques to do it,

such as

- Educational datamining from logdata (Malmberg et al 2015;2016).

- Process discovery (Malmberg et al., 2015, Sobocinsky et al., 2017)

- Lag sequential analysis (Malmberg et al., 2017, Kurki et al., 2017)

- T-pattern analysis (Kuvalja & Whitebread, 2014)

ANALYSIS PART II

1. Composing a process model to identify how groups

progress in their SSRL

(https://fluxicon.com/disco/)

- Fuzzy miner (Günther & Van Der Aals, 2007)

- More significant events are emphasized

- Highlights more important paths

2. Mine less structured processes

- Physiological synchrony

occured with the groups

who struggled with the

task.

- Earlier research has also

indicated, that

physiological synchrony is

correlated with group

tension and negative

expressions (Monster et

University of Oulu

‒ Aim:

- To explore how young children’s emotion and behaviour regulation manifests in socio-emotionally challenging situations in authentic educational settings and how the teacher’s presence makes a difference to it

‒ Context:

- Authentic open day-care activities, 2-5 year old children and teachers

‒ Data:

- Video-data of the activities. Focus in socio-emotionally challenging situations

Page 31: WHY PROCESS ANALYSIS? · University of Oulu EVENT DATA ‒How often a certain event occurs in the data? ‒Time stamped information 1) Need to categorise the data. -Data driven approach

What can we find out about children’s strategy use from this data?

Frequency of strategy use and their

quality (categorization of strategies)

Which

strategies

occur

together?

Which

strategies occur

teacher

interference?

Further research interests → Research questions

How do children respond to other children’s

behaviour in a challenging situation? Do

certain strategies cause another child to

respond in a certain way?

→ Research question How are the strategies

associated sequentially with other strategies?

What kinds of children’s behaviour makes

teachers interfere to children’s activities?

Does teacher interference, in turn, make

children use different strategies?

→ How are the strategies of children

associated sequentially with teacher

interference?
