1The answer reveals that the respondents fa il to understand that a new nucleus w ill be produced when a radioactive atom is broken.

2 According to the view o f constructivists, a person’s ideas w ill survive school education and form

an important basis fo r new learning.

3The solution is to consider lay ideas and combine factual knowledge w ith practical or political factors.

D ifferent types o f radioactive elements w ill make different health effects, according to characteristics o f each type.

It may be argued that the population should have a sufficient understanding o f radiation phenomena to secure individual safety as w ell as democratic decisions. To attain this, it is necessary fo r the communicators o f radiation inform ation to be fam iliar w ith the laypeople’s perceptions o f these phenomena. A questionnaire survey was conducted to examine non-experts’ conceptions o f radiation phenomena. The survey revealed an incomplete understanding o f concepts such as radioactive decay, h a lf-life and absorption o f radia tio n and a lack o f differentiation o f between radiation and radioactive materials. Many respondents did not distinguish between sources o f ionising radiation and other environmental hazards. Nuclear power plants and submarines were the most feared sources o f radiation. There are indications that the lay understanding o f radiation phenomena and risk is to a large extent formed by mass media and that “school knowledge” o f these phenomena is not applied in situations belonging to the “real w orld”To resolve this problem, new teaching and inform ation procedures are needed. These should take into account the learners’ perceptions and should integrate “school knowledge”w ith considerations belonging to the “real w orld”.

Numerous research studies demonstrate consistently that teaching promotes both language acquisition and academic Kasper, 1994; Krueger & Ryan, 1993; Snow & B rinton,Wesche, 1993). Students receiving linked instruction perform better in language courses than those not receiving such instruction (Kasper, 1997). They reap the benefits o f significant

content-based second language success (Grabe & Stoller, 1997; 1997; S tryker & Leaver, 1997;

gains in the second language, e.g., in the receptive skills o f listening and reading (Burger et al., 1997; Ready & Wesche, 1992) and in the productive skills o f w ritin g(Burger, 1989) and speaking (B urger &Chretien. 2001).They also achieve comparable or even better mastery o f d isciplinary content than ESL students or native English-speaking students not receiving content-based language instruction (Andrade &M akaafi, 2001; B abbitt, 2001; Kasper, 1994; W inter, 2004).

The topic sentence is “content-based second language teaching promotes both language acquisition and academic success.”The w rite r uses literature evidence to support the idea in term s o f speaking, reading and w ritin g.
