Readers build a mental representation of text during reading. The coherence building processes readers use to build a mental representation during reading is key to comprehension. We examined the effects of self- explanation on coherence building processes as undergraduates (n =51) read five complementary texts about natural selection and…

In this experiment we investigated whether the presentation of domain principles within one text facilitates reading to learn from multiple exemplar texts that feature the importance of the principles. There were five texts about natural selection: a principles text, which described principles of natural selection, and four exemplar-based texts…

Evolutionary trees are central to learning about evolutionary processes, yet students at all educational levels struggle to read and interpret them. The synthetic tree-reading model (STREAM), based on published and not yet empirically tested models, was tested to determine whether the assumed hierarchy of the model could be substantiated and how…

When reading scientific text, readers must draw inferences when the author does not make relations explicit; readers also need to pick up on causal relations that the author "does" make explicit. We collected think-aloud protocols from 86 undergraduate biology students reading 7 brief, illustrated passages about the immune system. After…

The purpose of this study was to investigate bridging inferences and learning when students with low topic knowledge read multiple complementary biology texts. Using a think-aloud protocol, we assessed students' (n = 74) cognitive processes while they read one text about principles of natural selection and three texts about examples of natural…

This study investigated the effects of task relevance instructions and topic beliefs on reading processes and memory for belief-related text. Undergraduates received task instructions (focus on arguments for vs. against) before reading a dual-position text. In Experiment 1 (n = 88), a reading time methodology showed no differences in reading time…

Teaching and learning evolution is challenging. Biology education research shows that the underlying evolutionary concepts are poorly understood among students. This prevents a meaningful understanding of the central biological concepts. The instructional format of self-explanation prompts seems to be promising to respond to these difficulties.…

We investigated the online and offline effects of learner and instructional characteristics on conceptual change of a robust misconception in science. Fifty-nine undergraduate university students with misconceptions about evolution were identified as espousing evaluativist or non-evaluativist epistemic beliefs in science. Participants were…

While researching student assumptions for the development of the Biology Concept Inventory (BCI; http://bioliteracy.net), we found that a wide class of student difficulties in molecular and evolutionary biology appears to be based on deep-seated, and often unaddressed, misconceptions about random processes. Data were based on more than 500…

This study examined students' active roles in constructing knowledge when learning new information in the domain of biological evolution. A computer-based connectionist methodology was developed to provide a way to present students with new information while the experimenter provides probe statements congruent with or contradictory to the…
