What Keeps a Young Adult Active in the Faith?

We’ve all heard the story before. A child grows up in a Christian home and seems completely committed to the faith. When the child grows up and leaves home, however, he leaves his faith behind. This, of course, is devastating to his parents, and they wonder what they did wrong. Should they have spent more time at church? Should they have emphasized apologetics (reasoned arguments in support of the Christian faith) more? Should they have limited his circle of friends more? Should they have sent him to a Bible college before letting him go off into the real world? What could they have done to make him realize that faith is important throughout the course of his life?

This is a real fear for many parents. They understand how important faith is in a person’s day-to-day life, and they want to spend eternity with their children. How can they avoid the heartache of seeing their children leave the faith? Not surprisingly, there are people who offer answers to that question. Some groups insist that children must be firmly grounded in a Christian worldview. As a result, they offer courses that they claim will help young adults keep their faith in a hostile world. Others insist that the problem lies in the fact that most young adults don’t know how to defend their faith against attacks. Thus, you need to firmly ground them in apologetics in order for them to keep their faith.

The core assumption involved with both of these “answers” is that young Christians just don’t know enough. They don’t know how to analyze the presuppositions that people use in forming their worldviews. They don’t know how to answer the objections that those who are skeptical of the Christian faith raise. They don’t know what parts of the Bible to read for guidance. If we could just teach them all the things they need to know, they will be firm in their faith for the rest of their lives.

Unfortunately, that core assumption is wrong. As a result, while things like worldview classes and apologetics books might be useful and helpful, they will do little to keep a young adult in the faith. What actually keeps a young adult active in the Christian faith? The answer might surprise you, but it really shouldn’t.

Not a CDC Coverup…A Case of Using the Wrong Analytical Method

Posted by jlwile on September 2, 2014

Sometimes, you can get the job done even when you use the wrong tool.  However, sometimes the wrong tool produces the wrong results.

Sometimes, you can get the job done even when you use the wrong tool. However, sometimes the wrong tool produces the wrong results.

The “news story” headline is astounding: “Fraud at the CDC uncovered, 340% risk of autism hidden from public.” The article says that data in a 2004 CDC study on the relationship between the Measles, Mumps, and Rubella (MMR) vaccine and autism were purposefully hidden so it could deny a relationship between the two. Those hidden data supposedly show that some who got the MMR vaccine were significantly more likely to become autistic than those who didn’t. According to the article, this shows that the original study is “fraudulent,” and there is now a petition to get the study retracted. It also calls into question the other studies that the CDC often cites to show that there is no relationship between vaccination and autism. And this article has to be reliable. After all, it is on CNN’s website, right?

Well, not exactly. If you go to the article, you will see “NOT VERIFIED BY CNN” at the top, and you will find a CNN producer note that this website is the network’s “user-generated news community.” So the article wasn’t written by someone at CNN. It was written by a blogger. Does that mean it’s not reliable? Of course not. I read several blogs regularly, and I find most of the articles written on them to be very reliable. In fact, I would say that some blogs are more reliable than some standard media outlets! The question, of course, is whether or not this particular blog article is reliable. When you look into the details, you find that it’s not.

The article’s big claim is that by including data which were supposedly covered up by the CDC, you can find that African American boys have a 340% increased risk of autism if they got the MMR vaccine. This conclusion, however, was “hidden due to pressure from senior officials.” Of course, to make such a claim, someone must have done some sort of study. The article itself tells you nothing about that study, but the CNN Producer Note at the top indicates that it was a study done by Dr. Brian Hooker (a bioengineer) and was published in a journal called Translational Neurodegeneration. An update to that note indicates that the journal has pulled the study, and the journal says this is “because of serious concerns about the validity of its conclusions.”

That doesn’t sound very good, but then again, maybe the journal has been pressured by the CDC to participate in their elaborate coverup. Fortunately, I was able to read the study before it was pulled, and I have to agree with the journal’s decision. The study’s conclusions are obviously wrong, because it used the wrong kind of tool to evaluate the data.

I write this blog post with a somewhat heavy heart. Apologia is in the process of producing Exploring Creation with Chemistry, Third Edition, which is an update of the high school chemistry course I wrote. Updating science books is a good thing, and when Apologia updated the Human Anatomy and Physiology course that I co-authored, I was very happy with the result. The new edition of that course is better than the old edition, no question about it. I wish I could say the same thing about the new edition of this chemistry course. So far, however, I cannot.

Now please understand that I haven’t seen the entire updated course yet. Although Apologia’s catalog indicated the new course would be available in July, they have delayed the release of the book. To help families who plan to use the new edition for this academic year, they have posted the first three modules of the course online. That’s what I have reviewed. There were 16 modules in the original course, and assuming this holds true for the new edition, that means I have reviewed only about 3/16 of the course.

In addition, please understand that since I wrote the original course, I am probably not as objective as I would like to be when evaluating the new edition. After all, I wrote what I thought was the best explanation of general chemistry that I could possibly give. Perhaps I can’t be satisfied with any update. However, I was very satisfied with the update of the Human Anatomy and Physiology course that I co-wrote, so I really hope I am being as objective as possible. I am certainly willing to believe that there’s a better way to teach chemistry than what I developed. I just don’t think this is it.

Finally, I have to say that I know one of the authors of the new edition personally (Rusty Hughes), and I consider him to be an excellent teacher. I also really like him as a person. I don’t want him (or the other author, who I do not know) to take offense. It’s just that many people have asked for my thoughts on this new edition, and I feel compelled to write them.

First Day of Class

Today was my first day teaching general chemistry at Anderson University. I promise I won’t be reporting on every class session, but I couldn’t resist talking about this one. I started the class with a little demo. Prior to class, I had soaked a Q-tip in a slightly acidic solution of phenolphthalein, an acid/base indicator. In presence of an acid, it is clear. In the presence of a base, it is pink. I used the Q-tip to write the name of the course (Chem 2110) on a large sheet of paper, and it dried clear. I soaked another Q-tip in a solution of potassium ferrocyanide (which is a light yellow color) and wrote my name on the same piece of paper, right over where I had written the course name. It also dried clear. When I set it up, then, the students saw a blank sheet of paper.

I then sprayed the paper with a very weak solution of sodium hydroxide. The base caused the phenolphthalein to turn pink, revealing the class name. It had no effect on the potassium ferrocyanide. I then sprayed the paper with a weakly acidic solution of iron (III) chloride. The acid caused the phenolphthalein to turn clear again, so the course name went away. The iron (III) chloride reacted with the potassium ferrocyanide to bring out my name in blue. I love that demo, and at least a few of the students seemed to appreciate it.

After going over the syllabus and discussing the mechanics of the course, I decided to start by giving one of the best descriptions of science I have ever heard. It comes from Dr. Henry F. Schaeffer III, the Graham Perdue Professor professor of Chemistry at the University of Georgia. He is one of the most important chemists of our time, and here is what he says about science:1

The significance and joy in my science comes in those occasional moments of discovering something new and saying to myself, ‘So that’s how God did it.’ My goal is to understand a little corner of God’s plan.

I told the students that as far as I am concerned, that’s what science is all about – figuring out how God did it and trying to understand a small piece of God’s amazing plan for His creation. I then went on to discuss the introductory material for the course.

I was pleased to find out that two of the 61 students in my class had used my high school chemistry book! I wrote that book to prepare students to study chemistry at the college level, and I have received many notes from students, parents, and teachers indicating that it has. It will be interesting to see whether or not these two students have a similar experience.

It looks like the semester is off to a good start!

Another Study Shows College Does Not Erode Faith – For Most Christians

Posted by jlwile on August 21, 2014

About a year ago I discussed a study that indicated a college education makes a person more likely to retain his or her faith. Recently, a new study on essentially the same topic was published in the same academic journal. It looked at data in a different (and very interesting) way, but its conclusions generally support those of the previous study.

The author, Dr. Philip Schwadel, used a well-known data set called the General Social Survey (GSS) for the years 1973 to 2010. He then looked at the years in which the respondents were born. He found that he had plenty of data for people born after 1900 and before 1980, so he focused on them. This gave him 38,251 people to analyze, which is an excellent sample size. In the GSS, the people are asked what their religious preference is: Protestant, Catholic, Jewish, some other religion, or no religion. They are also asked about their education and what kinds of degrees they have. Dr. Schwadel wanted to determine whether or not a college degree had any effect on a person answering “no religion.”

He found that people who were born from 1900 to 1964 were more likely to say they had no religion if they had a college degree. However, the amount by which they were more likely to say that dropped fairly steadily from 1915-1964. For those born in 1965, a college degree had no effect on whether or not they answered “no religion.” After 1965, having a college degree made a person less likely to indicate they had no religion. As the author says:1

Results from hierarchical age-period-cohort models using more than three and a half decades of repeated cross-sectional survey data demonstrate that the strong, positive effect of college education on reporting no religious affiliation declines precipitously across birth cohorts. Specifically, a bachelor’s degree has no effect on non-affiliation by the 1965–69 cohort, and a negative effect for the 1970s cohorts.

If we dig a bit deeper into the study, however, we find something even more interesting.

No, I am not going to earn another degree. You can’t teach this old dog any new tricks. However, for the first time since 1995, I will be teaching a college chemistry class. I have to admit that I am a bit nervous about it, simply because it has been so long. Of course, I am also excited about it for exactly the same reason. While I truly enjoy interacting with students over the internet, it will be fun to go back to the classroom and interact with students who are right there in front of me!

It’s not that I never get to interact with students in that way. After all, I travel to all sorts of homeschool conventions where I get to interact with lots of students and parents. Indeed, one of my favorite convention experiences was a session where I did nothing but answer student questions. In addition, I have been a guest lecturer at many universities, both in the U.S. and other countries. However, it has been nearly 20 years since I spent an entire semester teaching one group of students.

Whose students will be subjected to my presence for an entire semester? The science majors at Anderson University, about which I have written before (here and here). It is one of the few Christian universities at which I would be comfortable teaching, because it doesn’t have a long list of beliefs to which its professors must subscribe. Instead, it takes the mission of a university seriously – to tackle tough questions in as open-minded a way as possible.

I have added a new blog category called “College Chemistry,” in the hopes that I can write about my experiences over the course of this semester. I really have no idea whether or not I’ll actually do that. I’ll just have to see how it goes. As a final note, this doesn’t mean I am making a change in my career’s focus. I believe God has called me to work with homeschoolers, and I will continue to write and speak for them. This is (most likely) a one-time thing. It fills a one-time need that Anderson University currently has.

Yet Another Study Confirms The Effectiveness of Home Education

As far as I know, I first encountered homeschool graduates when I was on the faculty at Ball State University. The ones I met stood out, even in a crowded chemistry or physics classroom. The more I researched homeschooling, the more I came to learn that this was the norm. On average, homeschool graduates are better prepared for college than their peers (see here, here, here, and here, for example). As a result, I started working with homeschoolers, and I began to understand why my homeschool graduates at Ball State University stood out: Homeschooling is a superior form of education for most students.

The data continue to support this fact. Consider, for example, a study that was published in the March 2013 edition of Catholic Education. The author examined the academic records of 408 students at Ave Maria University, a Roman Catholic university in South Florida. It is a fairly young university, founded in 2003 by the same man who founded Domino’s Pizza. In my mind, it makes perfect sense that a pizza man would open a university. The two seem to go together! Specifically, the university was founded as a conservative alternative to some of the more liberal Roman Catholic universities that exist in the U.S. As a result, it attracts a lot of homeschoolers, most of whom are Roman Catholic.

In the sample the author studied, there were 137 public school graduates, 142 students who graduated from catholic schools, and 129 homeschool graduates. The author compared four things among the three groups of students: SAT or ACT score, college grade point average (GPA), GPA by major, and GPA in the university’s “core” curriculum. The results are very interesting, and they demonstrate yet again that homeschooled students are simply better prepared for college than their publicly- and privately-schooled counterparts.1

Confirmation of a Creationist Prediction Becomes Even More Stunning

Posted by jlwile on August 11, 2014

Nature is filled with amazing designs, which leads me to the conclusion that it is the product of a Magnificent Designer. Of course, many scientists disagree with that conclusion, and some of them try to argue against it by pointing out examples of what they think are bad designs in nature. One of the oft-cited examples is the retina of the human eye. As Dr. Michael Shermer puts it:1

The anatomy of the human eye shows that it is anything but “intelligently designed.” It is built upside down and backwards, with photons of light having to travel through the cornea, lens, aqueous fluid, blood vessels, ganglion cells, amacrine cells, horizontal cells, and biploar cells, before reaching the light-sensitive rods and cones that will transform the signal into neural impulses.

To understand what he is saying, look at the illustration above. When light hits the surface of the eye’s retina, it has to travel through layers of cells that essentially connect the retina to the rest of the nervous system. Only then can it reach the light-sensitive cells, called rods and cones, and be converted into a signal that can be sent to the brain. This, of course, seems backwards to most evolutionists. According to them, if the retina were designed intelligently, the rods and cones would be at the retinal surface so they are the first thing the light hits. That way, the connecting neurons could be placed behind the rods and cones so they don’t interfere with the light in any way.

Like most arguments inspired by evolution, the more we learned about the human retina, the less reasonable this argument became. Back in 2007, a study published in the Proceedings of the National Academy of Sciences of the USA showed that light doesn’t have to travel through the connecting neurons to reach the rods and cones. Instead, as shown in the illustration above (which appeared on the cover of the journal), there are special cells, called Müller cells, that collect the light and guide it to the rods and cones.2

Three years later (in 2010), an analysis published in Physical Review Letters concluded:3

The retina is revealed as an optimal structure designed for improving the sharpness of images.

The authors of the analysis showed that the position of the rods and cones in the retina combined with the way the Müller cells guide the light to them make them much less sensitive to light that is scattered within the eye itself. This, in essence, reduces the “noise” that the rods and cones would get from errant photons, making the overall image sharper and clearer.

I blogged about this previously, pointing out that it is precisely what creationists predicted and quite opposite what evolutionists maintained. I am bringing it up now because further research has confirmed the creationist prediction in an even more stunning way!

Road Salt Changes Butterflies, Perhaps for the Better

Posted by jlwile on August 7, 2014

Living in Indiana, I see snow plows spreading salt on the roads every winter. I don’t think much about them, because I have seen them all my life. However, I ran across an interesting study that indicates the salt they spread actually affects some of the insects that live near the road. Sodium chloride (the main ingredient in road salt) is such a ubiquitous chemical in nature that I never thought about how road salt might affect the flora and fauna that live near the side of the road, but the study indicates that for butterflies, the effect is significant.

The authors studied flora near the side of salted roads and found that the amount of sodium in the plants can be as much as 30 times what exists in the same plants that live more than 100 meters from the side of the road. That’s not very surprising, since most roads get salted quite a bit, especially during winters with lots of snow and ice. The surprising aspect of the study is the profound effect these elevated salt concentrations had on monarch butterflies that eat roadside milkweed while they are caterpillars.

The authors found that compared to monarch butterflies that ate milkweed plants in prairies far from the road, the male monarchs that ate salted roadside milkweed had much stronger flying muscles. The females were different, however. They had larger eyes than their prairie-raised counterparts.1 To confirm that it was really the salt having this effect and not some other chemical that might be found near the roadside, the authors reared cabbage white butterflies in the lab. They saw exactly the same effect – the males that ate a high-salt diet had stronger flying muscles, while the females had larger eyes.

Instant Cooperation Among Organisms

Anyone who has been reading this blog for a while knows that I am fascinated with mutualism – the phenomenon whereby organisms of different species live together in a mutually-beneficial way (see here, here, here, here, and here, for example). I think it is probably a glimpse of what nature was like before the Fall. Based on what I see in mutualism, I think that lots of species were designed to cooperate with one another, and many of the pathological relationships we see today are corrupted versions of previously-beneficial ones.

Evolutionists have a different view, of course. The generally-accepted view is that mutualism starts out with one species trying to exploit another species. Here, for example, is how the text Symbiosis: An Introduction to Biological Associations, Second Edition puts it:1

Indeed, it is difficult to conceive of two organisms starting out in a mutualistic association. Most mutualistic symbioses probably began as parasitic ones, with one organism attempting to exploit another one.

To be fair, the authors of this text do allow for another option. There are some relationships between organisms that seem neither harmful nor beneficial. Barnacles that live on whales, for example, seem to neither harm nor help the whales in most cases. These kinds of relationships are called commensal, and the authors allow for mutualism to start out as a commensal relationship and then evolve into a mutualistic one.

The key, however, is the first sentence in the quote. They say it is difficult to conceive of two organisms starting out in a mutualistic relationship. Why? Because evolutionists cannot allow for a grand design in nature. They can’t look at the relationships in an ecosystem and see how they fit together in an overall plan. Instead, they have to imagine some scenario in which relationships are cobbled together by selfish organisms that are only concerned with their own survival. If organisms live in a mutually-beneficial relationship today, it is only because they evolved together (in a process called coevolution) from a negative relationship or at least a relationship that didn’t begin as a mutually-beneficial one.

A new study indicates that at least in some cases, this evolutionary-inspired idea is wrong.
